20150006561
The present invention relates generally to online requests effected over computer networks such as the Internet and, more particularly, to methods and systems for handling online requests based on information known to a service provider.
Computer networks such as the Internet allow users to make various online requests. For example, a user can make a request for an online transaction (e.g., a request to purchase a product or service offered on a network site, a request to transfer funds to or from a financial account, etc.); a request for a delivery of a product or service to a particular place (e.g., a request to have food delivered to a house or other building); a request for an access to online private content (e.g., a request to access an online email account); a request for a download of data (e.g., a request to download a video file, an audio file, a software upgrade file, streaming video, streaming audio, etc.); etc.
In order to handle an online request made by a user, a network element (e.g., a server) processes information related to the online request and provided by the user. For example, where a user makes a request to purchase a product or service offered on a network site using a credit card, a server operated by a card issuing bank that issued the credit card typically processes credit card information (e.g., a card number, an expiry date, and/or a cardholder's name) provided by the user in order to approve or deny the online transaction attempted to be made by the user; where a user makes a request to have a given product or service delivered to a house or other building, a server operated by an entity responsible to effect this delivery typically processes a civic address of the house or other building provided by the user in order to determine where to deliver the product or service; where a user makes a request to access an online email account, a server operated by an entity providing the online email account typically processes a user name and password provided by the user in order to identify and control access to the online email account; etc.
Handling of an online request made by a user often involves verifying whether information related to the online request and provided by the user has been legitimately used by the user and/or can be trusted. For example, where a user makes a request to purchase a product or service offered on a network site and provides credit card information for this purpose, a verification as to whether the user is legitimately providing the credit card information is typically made in an effort to counter fraudulent online transactions; where a user makes a request to have a given product or service delivered to a house or other building and provides a civic address for this purpose, a verification as to whether the civic address is valid may be made in an effort to avoid delivery to a wrong or invalid address; etc.
While there are techniques for verifying whether information related to an online request and provided by a user making the online request has been legitimately used by the user and/or can be trusted, these techniques are sometimes inconvenient, cumbersome, and/or ineffective. In particular, existing techniques may be ineffective in situations where the information provided by the user is incorrect, out of date, or susceptible to fraud.
Accordingly, there remains a need for improvement in verifying whether information related to an online request and provided by a user making the online request has been legitimately used by the user and/or can be trusted.
As embodied and broadly described herein, the present invention provides a method comprising: obtaining first information, the first information relating to an online request made using a communication apparatus; using a logical identifier assigned to the communication apparatus to obtain second information, the second information pertaining to a profile associated with the logical identifier; comparing the first information to the second information; and performing an action related to handling of the online request based on a result of the comparing.
The present invention also provides an apparatus comprising an interface for receiving messages and a processing unit coupled to the interface. The processing unit is responsive to receipt of a message at the interface for: obtaining first information, the first information relating to an online request made using a communication apparatus; using a logical identifier assigned to the communication apparatus to obtain second information, the second information pertaining to a profile associated with the logical identifier; comparing the first information to the second information; and performing an action related to handling of the online request based on a result of the comparing.
The present invention also provides a computer-readable medium storing a program element for execution by a computer. The program element comprises: first program code for causing the computer to obtain first information, the first information relating to an online request made using a communication apparatus; second program code for causing the computer to use a logical identifier assigned to the communication apparatus to obtain second information, the second information pertaining to a profile associated with the logical identifier; third program code for causing the computer to perform a comparison of the first information to the second information; and fourth program code for causing the computer to perform an action related to handling of the online request based on a result of the comparison.
The present invention also provides a method comprising: receiving a first message conveying a logical identifier; consulting a database on a basis of the logical identifier to obtain information known to a service provider involved in assigning the logical identifier; processing the information to generate a second message to be used in handling an online request made using a communication apparatus to which is assigned the logical identifier; and transmitting the second message.
The present invention also provides an apparatus comprising an interface for receiving a first message conveying a logical identifier and a processing unit coupled to the interface. The processing unit is operative for: consulting a database on a basis of the logical identifier to obtain information known to a service provider involved in assigning the logical identifier; processing the information to generate a second message to be used in handling an online request made using a communication apparatus to which is assigned the logical identifier; and causing said interface to transmit the second message.
The present invention also provides a computer-readable medium storing a program element for execution by a computer. The program element comprises: first program code for causing the computer to receive a first message conveying a logical identifier; second program code for causing the computer to consult a database on a basis of the logical identifier to obtain information known to a service provider involved in assigning the logical identifier; third program code for causing the computer to process the information to generate a second message to be used in handling an online request made using a communication apparatus to which is assigned the logical identifier; and fourth program code for causing the computer to transmit the second message.
These and other aspects of the invention will become apparent to those of ordinary skill in the art upon review of the following description of embodiments of the invention in conjunction with the accompanying drawings.
A detailed description of embodiments of the present invention is provided herein below, by way of example only, with reference to the accompanying drawings, in which:
It is to be expressly understood that the description and drawings are only for purposes of illustration of example embodiments of the present invention and are an aid for understanding. They are not intended to be a definition of the limits of the invention.
In this embodiment, the communication apparatus 12 comprises a computing device 16 and a network interface unit 18. For example, the computing device 16 may be implemented as a personal computer (PC) such as a desktop computer, a laptop computer, or a tablet PC. The computing device 16 is provided with at least one input device such as a keyboard, a mouse, a touchscreen, a stylus, a microphone, etc., as well as a display and possibly one or more other output devices (e.g., speakers) that enable interaction between the user 10 and the computing device 16. The computing device 16 is operative to run a software application implementing a network browser (e.g., a web browser) with which the user 10 can interact via the display (and possibly one or more other output devices) and the at least one input device in order to access and interact with network sites of the public packet-switched network 14.
The network interface unit 18 enables the communication apparatus 12 to exchange data with the public packet-switched network 14 via a communication link 20. For example, in various embodiments, and depending on the nature of the communication link 20, the network interface unit 18 may be implemented as a modem such as a broadband modem (e.g., a digital subscriber line (DSL) modem or a cable model or a narrowband modem (e.g., a dial-up modem). Although it is shown as being a separate component in
The communication link 20 may traverse one or more network elements and comprise one or more physical links and one or more logical links. For example, the communication link 20 may comprise a physical link 17 between the network interface unit 18 and a network element 21. The physical link 17 may comprise a copper twisted pair, a coax cable, an Ethernet link, a fiber optic link (e.g., fiber to the premises (FTTP)), a fixed wireless link, a satellite link, or a combination thereof. Depending on the nature of the physical link 17, the network element 21 may be a DSL access multiplexer (DSLAM), a cable modem termination system (CMTS), or another type of network element. The communication link 20 may also comprise a dedicated logical link 19 between the network element 21 and another network element 23 that provides access to the public packet-switched network 14. For instance, the network element 23 may be a network access server (NAS), a router, etc. It will be appreciated that the communication link 20 may take on many forms in various embodiments.
While in this embodiment the communication apparatus 12 comprises the computing device 16 and the network interface unit 18, it will be appreciated that the communication apparatus 12 may comprise other components in other embodiments.
In order to exchange data with the public packet-switched network 14, the communication apparatus 12 is assigned a logical identifier. The logical identifier, which may be assigned to the computing device 16 or the network interface unit 18, may be an Internet Protocol (IP) address (e.g., in compliance with IPv4 or IPv6) or a proprietary address, label or tag. The logical identifier may be statically assigned to the communication apparatus 12 in which case it does not change over time (e.g., a static IP address). Alternatively, the logical identifier may be dynamically assigned to the communication apparatus 12 in which case it may change over time (e.g., a dynamic IP address).
The logical identifier may be assigned to the communication apparatus 12 by a network element that is part of the communication link 20 (e.g., the network element 23 in embodiments where it is a network access server). This network element may assign the logical identifier to the communication apparatus 12 when the communication apparatus 12 is activated (e.g., when the network interface unit 18 and/or the computing device 16 is/are powered-up) or otherwise regains network connectivity and/or at certain time intervals which may range from an hour or less to several months or more. For instance, in embodiments where the logical identifier is a dynamic IP address, the network element assigning the dynamic IP address to the communication apparatus 12 may do so in accordance with the Dynamic Host Configuration Protocol (DHCP) using a pool of IP addresses accessible to that network element. It will be recognized that assignment of the logical identifier to the communication apparatus 12 may be effected in various ways in various embodiments.
As mentioned previously, the user 10 can use the communication apparatus 12 to access and interact with network sites of the public packet-switched network 14. These network sites are implemented by servers 301 . . . 30N connected to the public packet-switched network 14. The servers 301 . . . 30N and the network sites that they implement are operated, managed or otherwise associated with various entities, including, for example, companies, governmental organizations, non-profit organizations, and individuals.
Each of the servers 301 . . . 30N comprises suitable hardware, firmware, software, control logic, or a combination thereof for implementing a plurality of functional components, including an interface and a processing unit. The interface of each of the servers 301 . . . 30N is adapted to receive and send data (e.g., in the form of messages) from and to communication apparatus (such as the communication apparatus 12) connected to the public packet-switched network 14 as well as other elements (e.g., computers or databases) communicatively coupled to that server but not necessarily connected to the packet-switched network 14. The processing unit of each of the servers 301 . . . 30N is adapted to effect various processing operations to implement that server's functionality.
Interaction of the user 10 with a network site implemented by a server 30n (1≦n≦N) typically involves the network browser implemented by the computing device 16 interacting with the server 30n in order to allow the user 10 to view, hear or otherwise be exposed to content (e.g., web pages) of the network site via the display and/or one or more other output devices of the computing device 16, and possibly to input information (e.g., by entering text, selecting an option, etc.) and/or one or more commands (e.g., by clicking on a graphical button or a hyperlink) via the at least one input device of the computing device 16.
Occasionally, during his/her interaction with the network site implemented by the server 30n, the user 10 may use the communication apparatus 12 to make an online request. The online request can be any request made online, i.e., any request made by way of the communication apparatus 12 transmitting data over the public packet-switched network 14. The online request can be a request for anything which can be requested online. For example, in various embodiments, the online request may be:
a request for an online transaction (e.g., a request to purchase a product or service offered on the network site implemented by the server 30n; a request to pay a bill for a previously obtained product or service via the network site; a request to transfer funds to or from an account, such as a bank account or an online wallet account, via the network site; a request to buy or sell securities (e.g., stocks, bonds, etc.) via the network site; a request to make a donation to a charity or other institution through the network site; etc.);
These examples are presented for illustrative purposes only and should not be considered limiting in any way since, as mentioned above, the online request can be a request for anything which can be requested online.
In making the online request while interacting with the network site implemented by the server 30n, the user 10 provides via the communication apparatus 12 information related to the online request. This information, which is hereinafter referred to as “request-related information”, can take on various forms depending on the nature of the online request being made. For example:
It will be appreciated that these examples are presented for illustrative purposes only since, as mentioned above, the request-related information can take on many different forms depending on the nature of the online request being made.
The request-related information may be provided by the user 10 via the communication apparatus 12 in various ways. For example, the user 10 may use the at least one input device of the computing device 16 to input the request-related information and cause this information to be sent by the communication apparatus 12 to the server 30n (or another computer associated with the server 30n) over the public packet-switched network 14. Alternatively, the request-related information may have been previously stored in a memory of the computing device 16, in which case the user 10 may use the at least one input device of the computing device 16 to cause the communication apparatus 12 to send the request-related information to the server 30n (or another computer associated with the server 30n) over the public packet-switched network 14.
Continuing with
Depending on the nature of the online request, in some embodiments, the request handling element 51 may be communicatively coupled to the server 30n via a communication path 79. The communication path 79 may be established over the public packet-switched network 14 and/or another network 59 (e.g., a financial network). For example, this may be the case where the online request is a request for an online transaction and the request handling element 51 is a transaction validation server remote from the server 30n. In such embodiments, the request handling element 51 comprises suitable hardware, firmware, software, control logic, or a combination thereof for implementing a plurality of functional components, including an interface and a processing unit. The interface of the request handling element 51 is adapted to receive and send data (e.g., in the form of messages) from and to servers, other computers and/or other elements (e.g., databases). The processing unit of the request handing element 51 is adapted to effect various processing operations to implement that element's functionality. In other embodiments, the request handling element 51 may be part of the server 30n. For example, this may be the case where the online request is a request for an access to online private content that is provided by the server 30n, a request for a download of data that is provided by the server 30n, or a request for a delivery of a product or service offered on the network site implemented by the server 30n.
As shown in
Specific contents of the database 53 will depend on the nature of the online request made by the user 10 and the functionality of the request handling element 51. A specific example of potential contents of the database 53 will be considered later on.
For now, suffice it to say that, in some embodiments, upon processing the request-related information provided by the user 10 via the communication apparatus 12, the request handling element 51 may use the personal information included in the record that is contained in the database 53 and that includes information matching the request-related information, in order to handle the online request made by the user 10. In these embodiments, by virtue of being used to handle the online request, the personal information included in the record that is contained in the database 53 can also be viewed as information related to the online request.
In some embodiments, the request handling element 51 and the database 53 may be part of separate network elements and communicatively coupled to one another via a communication link, which may traverse one or more network elements and comprise one or more physical links and one or more logical links. In other embodiments, the request handling element 51 and the database 53 may be part of a common network element. In yet other embodiments, the database 53 may be distributed amongst a plurality of network elements and/or physical locations.
With continued reference to
Interaction between the profile information server 34 and the request handling element 51 takes place over a communication link 61. The communication link 61 may be established over a network 63, which may comprise part of the public packet-switched network 14, a financial network and/or another network, and may traverse one or more network elements and comprise one or more physical links and one or more logical links. For example, the communication link 61 may be a dedicated and secure link established between the profile information server 34 and the request handling element 51. It will be recognized that the communication link 61 may be implemented in various manners in different embodiments.
The profile information server 34 has access to a profile information database 36. In some embodiments, the profile information server 34 and the profile information database 36 may be part of separate network elements and communicatively coupled to one another via a communication link, which may traverse one or more network elements and comprise one or more physical links and one or more logical links. In other embodiments, the profile information server 34 and the profile information database 36 may be part of a common network element. In yet other embodiments, the profile information database 36 may be distributed amongst a plurality of network elements and/or physical locations.
Referring additionally to
The profile in a record 40m (1≦m≦M) includes information known to a service provider involved in assigning the logical identifier that is associated with that profile. The service provider may be an access service provider (ASP, also sometimes called a regional access network provider (RANP)) that may or may not be an internet service provider (ISP). For example, the information in the record 40m may include:
This example of information content of a profile is presented for illustrative purposes only and should not be considered limiting in any respect. Generally, a profile that is associated with a given logical identifier assigned to a communication apparatus can include any information known to a service provider involved in assigning the given logical identifier to the communication apparatus.
An example process by which the profile information database 36 may be populated is described later on. For now, suffice it to say that the profile information database 36 stores the records 401 . . . 40M that associate profiles to logical identifiers.
The profile information server 34 is operative to use information included in the profile information database 36 as part of its interaction with the request handling element 51 in order to handle the online request made by the user 10 using the communication apparatus 12. To that end, the profile information server 34 comprises suitable hardware, firmware, software, control logic, or a combination thereof for implementing a plurality of functional components, including an interface and a processing unit. The interface of the profile information server 34 is adapted to receive and send data (e.g., in the form of messages) from and to the request handling element 51, and possibly other servers, computers and/or other elements (e.g., databases) communicatively coupled to the profile information server 34 via communication links (not shown) that may be established over the public packet-switched network 14 and/or another network and that may traverse one or more network elements and comprise one or more physical links and one or more logical links. The processing unit of the profile information server 34 is adapted to effect various processing operations to implement that server's functionality.
Operation of the profile information server 34, its interaction with the request handling element 51, as well as operation of other network elements, will now be illustrated in the context of an example where the online request made by the user 10 using the communication apparatus 10 is a request for an online transaction. More particularly, in this example, it is assumed that the user 10, while interacting with the network site implemented by the server 30n, makes a request to purchase a product or service offered on the network site using a particular credit card.
Accordingly, for purposes of this example, and with reference to
Also, for purposes of this example, the transaction validation server 51 has access to the aforementioned database 53, With additional reference to
Thus, referring to
The network site then prompts the user 10 to provide payment information to pay for the selected product or service. In this example, the user 10 thus proceeds to enter credit card information (e.g., a card number, an expiry date, and/or a cardholder's name) regarding the particular credit card. The user 10 then indicates his/her intent to submit an order to purchase the selected product or service using the entered credit card information, for instance, by selecting a “submit order” option on the network site.
At this point, the computing device 16 of the communication apparatus 12 transmits to the server 30n a message 102. In this example, the message 102 conveys (i) order information indicative of the selected product or service; (ii) purchase amount information indicative of an amount to be paid to purchase the selected product or service; and (iii) the credit card information entered by the user 10 to purchase the selected product or service. The message 102 may also convey the logical identifier assigned to the communication apparatus 12. Alternatively, the logical identifier assigned to the communication apparatus 12 may not be conveyed by the message 102 but may already be known to the server 30n due to prior interaction between the computing device 16 and the server 30n.
Since it travels over the public packet-switched network 14, the information to be transmitted to the server 30n as part of the message 102 may be encrypted by the computing device 16 prior to being transmitted to the server 30n. This encryption may be effected using the Secure Socket Layer (SSL) protocol or some other encryption technique, by virtue of interaction between the computing device 16 and the server 30n.
Upon receiving the message 102, the server 30n processes the message 102, possibly decrypting one or more of its portions, and proceeds to send a message 104 to a payment gateway 60. The payment gateway 60 is a network element that is connected to a financial network 68 and that is used by the server 30n to process online transactions attempted to be made via the network site implemented by the server 30n. The financial network 68 interconnects a plurality of servers or other computers associated with banks and/or other financial institutions, including, in this example, the transaction validation server 51 that is associated with the card issuing bank and a server 70 that is associated with an acquiring bank, i.e., a financial institution that is used by an entity, in this case, a merchant, which operates, manages or is otherwise associated with the server 30n.
The message 104 sent to the payment gateway 60 may be identical to the message 102, i.e., it may be a relayed version of the message 102. Alternatively, the message 104 may be generated by the server 30n based on the message 102 and possibly other information known to the server 30n (e.g., the logical identifier assigned to the communication apparatus 12, if not conveyed by the message 102 but already known to the server 30n). In this example, the message 104 conveys (i) the purchase amount information indicative of an amount to be paid to purchase the selected product or service; (ii) the credit card information entered by the user 10 to purchase the selected product or service; and (iii) the logical identifier assigned to the communication apparatus 12. Here again, information conveyed by the message 104 may he encrypted prior to transmission to the payment gateway 60.
Upon receiving the message 104, the payment gateway 60 processes the message 104, possibly decrypting one or more of its portions. Based on content of the message 104, the payment gateway 60 determines that it originates from the server 30n and proceeds to send a message 106, over the financial network 68, to the server 70, which is associated with the acquiring bank used by the merchant associated with the server 30n. The message 106, which can be viewed as a request for transaction authorization, is intended to elicit from the financial network 68 a response as to whether the online transaction requested by the user 10 is approved or denied. In this example, the payment gateway 60 generates the message 106 based on the message 104 such that the message 106 conveys (i) the purchase amount information indicative of an amount to be paid to purchase the selected product or service; (ii) the credit card information entered by the user 10 to purchase the selected product or service; and (iii) the logical identifier assigned to the communication apparatus 12.
The server 70 receives the message 106 and processes it to gain knowledge that a transaction involving the merchant associated with the server 30n is attempted to be effected. Based on the credit card information conveyed by the message 106, the server 70 proceeds to send a message 108 to the transaction validation server 51 over the financial network 68. The message 108 may be identical to the message 106, i.e., it may be a relayed version of the message 106. Alternatively, the message 108 may be generated by the server 70 based on the message 106 and possibly other information known to the server 70. In this example, the message 108 conveys (i) the purchase amount information indicative of an amount to be paid to purchase the selected product or service; (ii) the credit card information entered by the user 10 to purchase the selected product or service; and (iii) the logical identifier assigned to the communication apparatus 12.
The transaction validation server 51, which is associated with the card issuing bank that issued the particular credit card that has been used by the user 10 in making the request to purchase the selected product or service, receives the message 108. The transaction validation server 51 proceeds to process the message 108 to determine whether the online transaction requested by the user 10 is to be approved or denied.
As part of its operation, in accordance with an embodiment of the present invention and as a measure to counter fraudulent online transactions, the transaction validation server 51 uses personal information regarding a party to which has been issued the particular credit card used by the user 10 in order to determine whether the online transaction requested by the user 10 is to be approved or denied.
More particularly, in this embodiment, the transaction validation server 51 consults the database 53 to identify' a particular one of the records 571 . . . 57p that includes information matching the credit card information conveyed by the message 108. Upon identifying the particular one of the records 571 . . . 57p, the transaction validation server 51 obtains therefrom personal information regarding a party to which has been issued the particular credit card associated with that particular record. Specifically, the transaction validation server 51 obtains one or more elements (e.g., a name, a phone number, a civic address, and/or an email address) of the personal information included in the particular one of the records 571 . . . 57p.
For purposes of this example, assume that the transaction validation server 51 obtains from the particular one of the records 571 . . . 57p a name of the party to which has been issued the particular credit card used by the user 10 and associated with that particular record. It will be appreciated that, in other examples, various other elements of the personal information included in the particular one of the records 571 . . . 57p may be obtained by the transaction validation server 51 and used in determining whether the online transaction requested by the user 10 is to be approved or denied. It will also be appreciated that, in some cases, the personal information used by the transaction validation server 51 in determining whether the online transaction requested by the user 10 is to be approved or denied may be obtained by the transaction validation server 51 directly from the credit card information entered by the user 10 and conveyed by the message 108. For example, in some cases, the credit card information entered by the user 10 and conveyed by the message 108 may include a cardholder's name appearing on the particular credit card (i.e., the name of the party to which has been issued the particular credit card), in which cases this name may be obtained by the transaction validation server 51 directly from the message 108, rather than being obtained from the particular one of the records 571 . . . 57p.
Thus, in accordance with an embodiment of the present invention, the transaction validation server 51 effects a verification as to whether the name of the party to which has been issued the particular credit card used by the user 10 corresponds to a name included in a profile associated to the logical identifier assigned to the communication apparatus 12 used by the user 10. To that end, the transaction validation server 51 interacts with the profile information server 34 to effect this verification on a basis of the logical identifier assigned to the communication apparatus 12 and conveyed by the message 108.
With reference to
The profile information server 34 receives the message 110 and proceeds to process it. More particularly, in this embodiment, the profile information server 34 extracts the logical identifier assigned to the communication apparatus 12 and conveyed by the message 110, and consults the profile information database 36 in an attempt to find a particular one of the records 401 . . . 40M that corresponds to this logical identifier.
If the profile information server 34 is unable to find a particular one of the records 401 . . . 40M that corresponds to the logical identifier assigned to the communication apparatus 12 and conveyed by the message 110, the profile information server 34 may send to the transaction validation server 51 a message (not shown) indicating that no profile associated with this logical identifier, and thus no name included in such profile, can be found. Upon receiving this message, the transaction validation server 51 may take remedial action. For example, the transaction validation server 51 may deny the online transaction attempted to be made using the communication apparatus 12 without performing any further processing operation to assess whether it should he approved or denied. Alternatively, the transaction validation server 51 may perform additional processing operations to determine whether the online transaction requested by the user 10 is to be approved or denied, including processing operations to re-assess legitimacy of the online transaction requested by the user 10, i.e., to probe more deeply into whether the user 10 legitimately used the credit card information conveyed by the message 108. For instance, these additional processing operations may effect conventional verifications, such as a card security code (CSC) verification whereby the user 10 is asked to enter the particular credit card's CSC; an address verification system (AVS) whereby the user 10 is asked to enter a billing address for the particular credit card which is compared to an actual billing address known to the card issuing bank; a phone call to a party to which the card issuing bank issued the particular credit card to verbally confirm legitimacy of the online transaction requested by the user 10, etc.
For purposes of this example, assume that a particular one of the records 401 . . . 40M corresponds to the logical identifier assigned to the communication apparatus 12 and conveyed by the message 110. The profile information server 34 thus finds the particular one of the records 401 . . . 40M, which associates the logical identifier assigned to the communication apparatus 12 (and conveyed by the message 110) to a profile including information known to a service provider involved in assigning the logical identifier to the communication apparatus 12. This information includes personal information regarding a party to which the service provider provides a network access service. In this case, this personal information includes a name of the party to which the service provider provides a network access service. Based on the message 110, which requests a confirmation as to whether the logical identifier assigned to the communication apparatus 12 is associated with a profile which includes a name that corresponds to name of the party to which has been issued the particular credit card used by the user 10, the profile information server 34 obtains from the particular one of the records 401 . . . 40M the name of the party to which the service provider provides a network access service.
The profile information server 34 proceeds to compare the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) to the name of the party to which has been issued the particular credit card used by the user 10 (conveyed by the message 110). Based on a result of this comparison, the profile information server 34 performs an action related to validation of the online transaction requested by the user 10 using the communication apparatus 12. More specifically, in this embodiment, the action performed by the profile information server 34 comprises generating and transmitting to the transaction validation server 51 a message 112 that indicates whether the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) corresponds to the name of the party to which has been issued the particular credit card used by the user 10 (conveyed by the message 110). This action is related to validation of the online transaction requested by the user 10 since the message 112 will be used by the transaction validation server 51 to validate the online transaction, as discussed below.
The transaction validation server 51 receives the message 112 and processes it to learn whether the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) corresponds to the name of the party to which has been issued the particular credit card used by the user 10 (conveyed by the message 110). As discussed below, the transaction validation server 51 handles the request for the online transaction made by the user 10 in different manners depending on whether the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) corresponds to or does not correspond to the name of the party to which has been issued the particular credit card used by the user 10 (conveyed by the message 110).
If the message 112 indicates that the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) does not correspond to the name of the party to which has been issued the particular credit card used by the user 10 (conveyed by the message 110), the transaction validation server 51 concludes based on the message 112 that legitimacy of the request for the online transaction made by the user 10 is not established. This may result in the online transaction being denied by the transaction validation server 51 without performing any further processing operation to assess whether it should be approved or denied. Alternatively, this may result in the transaction validation server 51 performing additional processing operations to determine whether the online transaction requested by the user 10 is to be approved or denied, including processing operations to re-assess legitimacy of the request for the online transaction made by the user 10, i.e., to probe more deeply into whether the user 10 legitimately used the credit card information conveyed by the message 108. For instance, and as mentioned above, these additional processing operations may effect conventional verifications, such as a card security code (CSC) verification, an address verification system (AVS), a phone call to verbally confirm legitimacy of the online transaction requested by the user 10, etc.
On the other hand, if the message 112 indicates that the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) corresponds to the name of the party to which has been issued the particular credit card used by the user 10 (conveyed by the message 110), the transaction validation server 51 concludes based on the message 112 that legitimacy of the request for the online transaction made by the user 10 is established. In other words, the transaction validation server 51 concludes based on the message 112 that the request for the online transaction made by the user 10 is legitimate, i.e., that the user 10 legitimately used the credit card information entered at step 200 and conveyed in the message 108.
The transaction validation server 51 proceeds to perform other processing operations to determine whether the online transaction requested by the user 10 is to be approved or denied. Approval or denial of the online transaction can be determined based on various factors. For example, based on the additional information (e.g., a credit limit, a balance due, etc.) included in the particular one of the records 571 . . . 57P and the purchase amount information indicative of an amount to be paid to purchase the selected product or service that is conveyed by the message 108, the transaction validation server 51 may determine whether the online transaction is to be approved or denied. It will be appreciated that approval or denial of the online transaction may be determined by the transaction validation server 51 based on other factors.
Upon determining whether the online transaction is approved or denied, the transaction validation server 51 sends a message 114 to the server 70 over the financial network 68. The message 114 indicates whether the online transaction is approved or denied. If the online transaction is denied, the message 114 may indicate (e.g., by a code) a reason for this denial, such as insufficient funds, an unavailable bank link, etc.
The server 70 receives the message 114 and processes it to know whether the online transaction is approved or denied. If approved, the online transaction is eventually settled via a settlement process involving the acquiring bank and the card issuing bank. This settlement process is well known and thus not described herein.
The server 70 proceeds to send a message 116 to the payment gateway 60. The message 116 may be identical to the message 114, i.e., it may be a relayed version of the message 114. Alternatively, the message 116 may be generated by the server 70 based on the message 114. The message 116 indicates whether the online transaction is approved or denied and, if applicable, may indicate a reason for denial of the online transaction,
Upon receiving the message 116, the payment gateway 60 processes it and proceeds to send a message 118 to the server 30n. Generated by the payment gateway 60 on a basis of the message 116, the message 118 indicates whether the online transaction is approved or denied and, if applicable, may indicate a reason for denial of the online transaction. Information conveyed by the message 118 may he encrypted by the payment gateway 60 prior to being transmitted to the server 30n.
The server 30n receives the message 118. The server 30n processes the message 118, possibly decrypting one or more of its portions, to ascertain whether the online transaction is approved or denied. Approval or denial of the online transaction (and a reason for denial, if applicable) may be recorded by the server 30n for future reference. The server 30n proceeds to send a message 120 to the computing device 16 of the communication apparatus 12 in order to communicate approval or denial of the online transaction to the user 10. Since it travels over the public packet-switched network 14, information conveyed by the message 120 may be encrypted by the server 30n prior to being transmitted to the computing device 16.
Upon receiving the message 120, the computing device 16 processes the message 120, possibly decrypting one or more of its portions, so as to communicate approval or denial of the online transaction to the user 10. For example, this may be achieved by displaying a “transaction approved” or “transaction denied” message (or any conceivable variant thereof) on the display of the computing device 16.
It will thus be appreciated that validation of the online transaction requested by the user 10 can be effected using information known to the service provider involved in assigning the logical identifier to the communication apparatus. This enables the transaction validation server 51 to conveniently and efficiently establish legitimacy of the request for the online transaction made by the user 10 in a way that is transparent to the user 10.
While the above-described example illustrates one possible manner of verifying whether the name of the party to which has been issued the particular credit card used by the user 10 corresponds to a name included in a profile associated to the logical identifier assigned to the communication apparatus 12 used by the user 10, it will be appreciated that this verification may be effected in various other manners in other embodiments.
For example,
The transaction validation server 51 sends a message 110* to the profile information server 34 over the communication link 61. In this embodiment, the message 110* can be viewed as a request to obtain a name included in a profile that is associated with the logical identifier assigned to the communication apparatus 12 (and conveyed by the message 108). The message 110* thus conveys the logical identifier assigned to the communication apparatus 12.
The profile information server 34 receives the message 110* and proceeds to process it. More particularly, in this embodiment, the profile information server 34 extracts the logical identifier assigned to the communication apparatus 12 and conveyed by the message 110*, and consults the profile information database 36 in an attempt to find a particular one of the records 4030nthat corresponds to this logical identifier.
If the profile information server 34 is unable to find a particular one of the records 401 . . . 40M that corresponds to the logical identifier assigned to the communication apparatus 12 and conveyed by the message 110*, the profile information server 34 may send to the transaction validation server 51 a message (not shown) indicating that no profile associated with this logical identifier, and thus no name included in such profile, can be found. Upon receiving this message, the transaction validation server 51 may take remedial action. For example, the transaction validation server 51 may deny the online transaction attempted to be made using the communication apparatus 12 without performing any further processing operation to assess whether it should be approved or denied. Alternatively, the transaction validation server 51 may perform additional processing operations to determine whether the online transaction requested by the user 10 is to be approved or denied, including processing operations to re-assess legitimacy of the online transaction requested by the user 10, i.e., to probe more deeply into whether the user 10 legitimately used the credit card information conveyed by the message 108. For instance, these additional processing operations may effect conventional verifications, such as a card security code (CSC) verification whereby the user 10 is asked to enter the particular credit card's CSC; an address verification system (AVS) whereby the user 10 is asked to enter a billing address for the particular credit card which is compared to an actual billing address known to the card issuing bank; a phone call to a party to which the card issuing bank issued the particular credit card to verbally confirm legitimacy of the online transaction requested by the user 10, etc.
For purposes of this example, assume that a particular one of the records 401 . . . 40M corresponds to the logical identifier assigned to the communication apparatus 12 and conveyed by the message 110*. The profile information server 34 thus finds the particular one of the records 401 . . . 40M, which associates the logical identifier assigned to the communication apparatus 12 (and conveyed by the message 110*) to a profile including information known to a service provider involved in assigning the logical identifier to the communication apparatus 12. This information includes personal information regarding a party to which the service provider provides a network access service. In this case, this personal information includes a name of the party to which the service provider provides a network access service. The profile information server 34 thus obtains from the particular one of the records 401 . . . 40M the name of the party to which the service provider provides a network access service.
The profile information server 34 proceeds to perform an action related to validation of the online transaction requested by the user 10 using the communication apparatus 12. In this embodiment, the action performed by the profile information server 34 comprises generating and transmitting to the transaction validation server 51 a message 112* that conveys the name obtained from the particular one of the records 401 . . . 40M, i.e., the name of the party to which the service provider provides a network access service. This action is related to validation of the online transaction requested by the user 10 since the message 112* will be used by the transaction validation server 51 to validate the online transaction, as discussed below.
The transaction validation server 51 receives the message 112* and processes it. More particularly, the transaction validation server 51 compares the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M of the database 36) to the name of the party to which has been issued the particular credit card used by the user 10 (obtained from the particular one of the records 571 . . . 57P of the database 53 at step 240). Based on a result of this comparison, the transaction validation server 51 performs an action related to validation of the online transaction requested by the user 10 using the communication apparatus 12. More specifically, in this embodiment, the action performed by the transaction validation server 51 comprises validating the online transaction requested by the user 10 in different manners depending on a result of this comparison.
If the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) does not correspond to the name of the party to which has been issued the particular credit card used by the user 10 (obtained from the particular one of the records 571 . . . 57P), the transaction validation server 51 concludes that legitimacy of the request for the online transaction made by the user 10 is not established. This may result in the online transaction being denied by the transaction validation server 51 without performing any further processing operation to assess whether it should be approved or denied. Alternatively, this may result in the transaction validation server 51 performing additional processing operations to determine whether the online transaction requested by the user 10 is to be approved or denied, including processing operations to re-assess legitimacy of the request for the online transaction made by the user 10, i.e., to probe more deeply into whether the user 10 legitimately used the credit card information entered at step 200 and conveyed in the message 108. For example, as mentioned above, these additional processing operations may effect conventional verifications, such as a card security code (CSC) verification, an address verification system (AVS), a phone call to verbally confirm legitimacy of the online transaction requested by the user 10, etc.
On the other hand, if the name of the party to which the service provider provides a network access service (obtained from the particular one of the records 401 . . . 40M) corresponds to the name of the party to which has been issued the particular credit card used by the user 10 (obtained from the particular one of the records 571 . . . 57P), the transaction validation server 51 concludes that legitimacy of the request for the online transaction made by the user 10 is established. In other words, the transaction validation server 51 concludes that the request for the online transaction made by the user 10 is legitimate, i.e., that the user 10 legitimately used the credit card information entered at step 200 and conveyed in the message 108.
The transaction validation server 51 proceeds to perform other processing operations to determine whether the online transaction requested by the user 10 is to be approved or denied. Approval or denial of the online transaction can be determined based on various factors. For example, based on the additional information (e.g., a credit limit, a balance due, etc.) included in the particular one of the records 571 . . . 57P and the purchase amount information indicative of an amount to be paid to purchase the selected product or service that is conveyed by the message 108, the transaction validation server 51 may determine whether the online transaction is to be approved or denied. It will be appreciated that approval or denial of the online transaction may he determined by the transaction validation server 51 based on other factors.
Upon determining whether the online transaction is approved or denied, the transaction validation server 51 sends the message 114 to the server 70 over the financial network 68, as described above in connection with
While this variant illustrates another possible manner of verifying whether the name of the party to which has been issued the particular credit card used by the user 10 corresponds to a name included in a profile associated to the logical identifier assigned to the communication apparatus 12 used by the user 10, it will be appreciated that this verification may be effected in various other manners in other embodiments.
Although the example considered above relates to an online transaction involving an online purchase using a credit card, principles described herein apply to other types of online transactions, including, for example, those involving online purchases or payments using other payment objects (e.g., digital cash, electronic checks) or online fund transfers involving accounts (e.g., bank accounts, online wallet accounts).
Also, while in the example considered above the online request made using the communication apparatus 12 is a request for an online transaction, principles described herein apply to other types of online requests, including a request for a delivery of a product or service to a particular place, a request for an access to online private content, a request for an access to a private network, a request for a download of data, or any other request that can be made online.
In addition, while in the example considered above the online request made using the communication apparatus 12 is handled on a basis of a name known to a service provider involved in assigning the logical identifier to the communication apparatus 12, other information known to the service provider and part of the profile associated with this logical identifier may be used in other cases, depending on the nature of the online request being made. For example, where the online request is a request for a delivery of a product or service to a particular place, a civic address known to the service provider may be used to handle the requested delivery; where the online request is a request for a download of data to the communication apparatus 12, a bandwidth known to the service provider to he available to the communication apparatus 12 may be used to handle the requested download of data; etc.
Furthermore, while in the above-considered example certain messages are exchanged between various elements of the architecture depicted in
Moreover, although in the above-considered example the transaction validation server 51 interacts with the profile information server 34, it will be appreciated that, in other embodiments, other network elements may interact with the profile information server 34 as part of a process to handle an online request made by the user 10 via the communication apparatus 12. For example, in some embodiments, and depending on the nature of the online request, the payment gateway 60, the server 70, the server 30n or any other network element may interact with the profile information server 34 as part of a process to handle an online request made by the user 10 via the communication apparatus 12.
Also, while the above-described example relates to an online request made over the public packet-switched network 14, it will be recognized that principles described herein can be applied to an online request made over a private packet-switched network.
Turning now to
This example will illustrate one possible manner by which an association between the logical identifier assigned to the communication apparatus 12 and a profile including information known to a service provider involved in assigning the logical identifier to the communication apparatus 12, may be stored in the profile information database 36 as part of one of the records 401 . . . 40M.
In this example, a given service provider owning, managing or otherwise associated with one or more network elements of the communication link 20 connecting the communication apparatus 12 to the public packet-switched network 14 provides a network access service to a given party (who may or may not be the user 10) occupying, owning, managing or otherwise associated with premises where the communication apparatus 12 is located. In order to benefit from the network access service, the given party has a business relationship with the given service provider. As part of this business relationship, the given party interacts with the given service provider (e.g., during a registration or service activation phase) to provide personal information regarding itself For example, this personal information may include a name, a gender, a date of birth or an age, a nationality, a correspondence language, a civic address (e.g., a residential or work address), a phone number (e.g., a residential, work, VoIP or mobile phone number), an email address, and/or an IM identifier of the given party. If the given party is more than one person, personal information regarding each such person may be provided. During interaction with the given service provider, the given party also indicates a service point location (e.g., a service address) where the network access service is to be delivered, selects a level of service to be obtained, provides billing information (e.g., a billing address and/or credit card information) to pay for the network access service, etc. Interaction between the given party and the given service provider may take place via a customer service representative of the given service provider or via a web site implemented by the given service provider.
The given service provider stores in the profile information database 36 a profile associated with the given party, in which is included information provided by the given party while interacting with the given service provider and possibly other information not obtained from the given party but pertaining to the network access service provided to the given party.
In this example, the infrastructure described above in connection with Figure I and partly shown in
Also, in this example, the network element 21 of the communication link 20 connecting the communication apparatus 12 to the public packet-switched network 14 is an access multiplexer under control of the given service provider. In one embodiment, the access multiplexer 21 may be a DSLAM.
The access multiplexer 21 is connected to the network element 23, which, in this embodiment, is a network access server (NAS) operated by the given service provider. The NAS 23, which may also sometimes be referred to as a broadband remote access server (BRAS), a remote access server (RAS) or a broadband access server (BAS), provides access to the public packet-switched network 14. Communication between the access multiplexer 21 and the NAS 23 can take place over the dedicated logical link 19 between these elements. The dedicated logical link 19, which may traverse an intervening access data network (not shown), can be implemented in various ways. For example, in one embodiment, the dedicated logical link 19 may be implemented as an asynchronous transfer mode (ATM) permanent virtual circuit (PVC). In another embodiment, the dedicated logical link 19 may be implemented as a virtual local area network (VLAN). It will be appreciated that various other implementations of the dedicated logical link 19 are possible.
The access multiplexer 21 allows data arriving from the NAS 23 along given ATM PVCs, VLANs or other dedicated logical links to be sent over corresponding physical links via corresponding one of its ports, and vice versa. Thus, the access multiplexer 21 can be said to implement a mapping 134 between, on the one hand, dedicated logical links and, on the other, ports of the access multiplexer 21. In this example, the mapping 134 implemented by the access multiplexer 21 relates the dedicated logical link 19 to the port 104 of the access multiplexer 21, In two example embodiments, the mapping 134 can be maintained by either the access multiplexer 21 or the OSS 122.
The infrastructure shown in
In this example, the NAS 23 is operative to maintain a pool 127 of logical identifieres that can be used by various communication apparatus, including the communication apparatus 12. In some embodiments, the pool 127 of addresses may be built up as a cooperative effort between the NAS 23 and the OSS 122, while in other embodiments, it may not be necessary for the OSS 122 to be involved in creating the pool 127 of logical identifiers. In still other embodiments, the pool 127 of logical identifiers may be maintained by the authorization element 142, and may be made accessible to the authorization element 142 without needing to pass through the NAS 23.
The profile information server 34, and the profile information database 36 that it has access to, can be linked to other components of the infrastructure of
As previously mentioned, in some embodiments, the profile information server 34 and the profile information database 36 may be part of separate network elements and communicatively coupled to one another via a communication link, which may traverse one or more network elements and comprise one or more physical links and one or more logical links. In other embodiments, the profile information server 34 and the profile information database 36 may be part of a common network element. In yet other embodiments, the profile information database 36 may be distributed amongst a plurality of network elements and/or physical locations. Also, it should be appreciated that the profile information database 36 may be managed, maintained and/or updated by an entity that may be the given service provider or a different entity.
It will be appreciated that numerous modifications and variations of the infrastructure of
Reference is now made to
It is recalled that once the logical identifier 193 has been obtained from the pool 127 of logical identifieres (either by the NAS 23 or by the authorization element 142), the NAS 23 assigns the logical identifier 193 to the dedicated logical link 19.
In an embodiment where the profile information server 34 is connected to the NAS 23 by the link 175, the fact that the NAS 23 assigns the logical identifier 193 to the dedicated logical link 19 allows the NAS 23 to construct and maintain a mapping 144 between, on the one hand, various dedicated logical links (such as the dedicated logical link 19 and others) and, on the other, logical identifieres corresponding to those dedicated logical links.
In an embodiment where the profile information server 34 is connected to the authorization element 142 by the link 177, the logical identifier 193 and the identity of the dedicated logical link 193 to which it is assigned are sent back by the NAS 23 to the authorization element 142, and it is the authorization element 142 that maintains the aforementioned mapping 144 between dedicated logical links and logical identifieres corresponding to those dedicated logical links.
Of course, those skilled in the art will be able to think of other ways of causing the communication apparatus 12 to send the access request 184 over the logical connection 182 between the communication apparatus 12 and the NAS 23, as well as other ways of assigning a logical identifier to the dedicated logical link 19 and thus to the communication apparatus 12. It should further be mentioned that, in some cases, the establishment of the aforementioned PPPoE, PPP and/or IPCP sessions may not be required. This is particularly the ease where the dedicated logical link 19 is a VLAN.
In view of the preceding description, and in particular given the previously described mappings 124, 134 maintained in the OSS 122 and/or the access multiplexer 21 and the mapping 144 maintained in the NAS 23 or the authorization element 142, the following describes how one can create an association between logical identifieres and service point locations.
Specifically, with reference to
Next, the profile information server 34 may be operative to combine the intermediate mapping 166 (received from the OSS 122) with the aforementioned mapping 144 (received from the NAS 23 or the authorization element 142), thus creating a final mapping 176 between, on the one hand, logical identifieres and, on the other, service point locations of communication apparatus having logical connections with the NAS 23 which traverse respective dedicated logical links to which those logical identifieres have been assigned. In this example, the final mapping 176 would specify that the logical identifier 193 corresponds to the service point location of the communication apparatus 12, i.e., the location of the service point where the communication apparatus 12 is located.
It is recalled that the profile associated with the given party and stored in the profile information database 36 by the given service provider includes the service point location where the network access service is to be delivered to the given party. Thus, based on the final mapping 176 specifying that the logical identifier 193 corresponds to the service point location of the communication apparatus 12, the profile information server 34 associates, in the profile information database 36, the profile associated with the given party to the logical identifier 193 assigned to the communication apparatus 12.
From the above, it should be apparent that the profile information database 36 can be populated with logical identifieres and profiles associated with these logical identifieres.
While the above-described example illustrates one possible technique for populating the profile information database 36, it will be appreciated that other techniques may be employed in other embodiments. For example, in some embodiments, the aforementioned credentials, which may be hard coded or programmably installed on the communication apparatus 12 or entered by the user 10 of the communication apparatus and which may be included in the access request 184 sent by the communication apparatus 12 to the NAS 23, can be used to associate the logical identifier 193 assigned to the communication apparatus 12 to the profile associated with the given party and stored in the profile information database 36. Specifically, these credentials, which are known by the service provider to have been provided to the given party, may be linked by the given service provider to the profile associated with the given party. Upon receiving the credentials as part of the access request 184 and assigning the logical identifier 193 to the communication apparatus 12, the given service provider may associate, in the profile information database 36, the profile associated with the given party to the logical identifier 193 assigned to the communication apparatus 12.
It will also be appreciated that, in embodiments where the logical identifier is dynamically assigned to the communication apparatus 12 (e.g., a dynamic IP address), the profile information database 36 may be updated accordingly.
Although in embodiments described above the communication apparatus 12 is directly connected to the communication link 20, it will be appreciated that, in some embodiments, the communication apparatus 12 may be connected to a router that is connected to the communication link 20 and that may be connected to one or more other communication apparatuses at premises where the communication apparatus 12 is located. In such embodiments, the router may perform network address translation (NAT) for packets passing therethrough. Depending on the type of NAT performed, in some cases, the logical identifier assigned to the communication apparatus 12 may include a portion identifying the router and a portion identifying the communication apparatus 12 connected thereto. For instance, the logical identifier assigned to the communication apparatus 12 may include an IP address assigned to the router, as well as a port number of a port of the router to which is connected the communication apparatus 12 or a local IP address assigned to the communication apparatus 12 by the router.
Also, while in embodiments considered above the profile information server 34 interacts with the request handling element 51 using the information included in the particular one of the records 401 . . . 40M in the profile information database 36 without the user 10 being explicitly informed of this fact, in other embodiments there may be mechanisms to notify the user 10 of this fact or confirm with the user 10 that he/she allows this information to be used by the profile information server 34 in its interaction with the request handling element 51. For example, in some embodiments, an applet, widget or other suitable element may be implemented to notify the user 10 via the computing device 16 (e.g., via a pop-up window) of the interaction between the profile information server 34 and the request handling element 51 and possibly to allow the user 10 to confirm whether information (or control which information) included in the particular one of the records 401 . . . 40M in the profile information database 36 can be used by the profile information server 34 as part of this interaction. As another example, the given party (who may or may not he the user 10) occupying, owning, managing or otherwise associated with premises where the communication apparatus 12 is located may have previously authorized the service provider providing the network access service to the communication apparatus 12 (e.g., during a registration phase) to use information contained in the particular one of the records 401 . . . 40M as part of a process to handle an online request made via the communication apparatus 12.
In addition, although embodiments described above considered online requests that the user 10 can make using the communication apparatus 12 while interacting with network sites implemented by the servers 301 . . . 30N, it will be appreciated that, in other embodiments, the user 10 may make an online request during a telephone call established (at least partly) over the public packet-switched network 14 (or a private packet-switched network) and such online request may be handled using principles described herein. In such embodiments, the communication apparatus 12 may comprise a VoIP phone, a Plain Old Telephone Service (POTS) phone equipped with an analog terminal adapter (ATA), or a soft phone (i.e., a computer equipped with telephony software). For example, during a call with a representative a customer service representative or other employee) of a given entity (e.g., a company, governmental organization, non-profit organization, etc.), the user 10 may make a certain request. In doing so, the user 10 may verbally provide request-related information that may need to be verified in order to handle the user's request. In this case, a server operated by the given entity may determine the logical identifier assigned to the communication apparatus 12 (based on packets received during the call) and may use this logical identifier to exchange messages with the profile information server 34 in order to effect verification of the request-related information provided by the user 10. Interaction between the server operated by the given entity and the profile information server 34 may be similar to interaction between the request handling element 51 and the profile information server 34.
Those skilled in the art will appreciate that, in some embodiments, certain functionality of a given component described herein (e.g., the profile information server 34 or the request handling element 51) may be implemented as pre-programmed hardware or firmware elements (e.g., application specific integrated circuits (ASICs), electrically erasable programmable read-only memories (EEPROMs), etc.) or other related elements. In other embodiments, a given component described herein (e.g., the profile information server 34 or the request handling element 51) may comprise a processor having access to a code memory which stores program instructions for operation of the processor to implement functionality of that given component.
