COMPUTING SYSTEM RECORD SECURITY ARCHITECTURE

BACKGROUND

Computing systems are currently in wide use. As one example, a computing system stores data as entities or other data records, and commonly includes process functionality that facilitates performing various processes or tasks on the data. Users log into or otherwise access the computing system in order to perform the processes and tasks. The data can include user data as well as entities or records that are used to describe various aspects of the computing system.

The data records (or entities) can be of any of a variety of different types. For example, in an enterprise system such as a customer resource management (CRM) or enterprise resource planning (ERP) system, a record can comprise data for an organization. Some examples include sales records, customer records, opportunity records, employee records, etc. In the context of a calendaring application, for example, an event record includes data for a particular event, such as a meeting. In one particular example, a meeting record can define a date, time, location, subject matter or description, as well as associated users or invitees for a meeting event.

The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.

SUMMARY

A computing system record security architecture comprises, in one example, a record generation component configured to receive a record generation request that includes a set of attributes and to generate a record in a computing system based on the record generation request, wherein the record includes the set of attributes and an owner property that identifies a first user as an owner of the record. The architecture comprises a record security component configured to receive a record modification request that requests a modification to the record, to analyze an identifier in the record modification request that identifies a second user as a sender of the record modification request, and to process the record modification request based on an analysis of the identifier in the record modification request relative to the owner property of the record.

DETAILED DESCRIPTION

The present disclosure generally relates to a security architecture for creating computing system records and enforcing record ownership privileges. Before describing embodiments of the security architecture in detail, a brief overview of record creation and ownership will be provided for the sake of illustration, but not by limitation.

In one particular example, a first user creates an event record (e.g., a meeting record) by defining a set of attributes, including a set of invitees and other event data such as location, data, time, etc. This event record is stored in the first user's system, and an event message comprising a record generation request is sent to the invitees. For instance, the first user's email server sends an email to the email server(s) of the invitees to replicate the event record in the invitees' system(s) as well. This type of architecture is often referred to as an email replication system, as opposed to a system that uses cross-server calls directly between servers. It is noted that the mailboxes of the invitees can be on the same server and/or different servers from the first user.

The first user is considered the event organizer, and thus the owner of the event record. The organizer, or owner, has a set of ownership privileges over the record which allows the organizer to modify the record, including updating and/or deleting the record.

In response to the requests sent by the first user, the invitees can accept or decline the event invitation. In this example, copies of the event record are created and stored within the invitees' system(s). Thus, the invitee users do not access the owner's event record directly, but rather copies of the event record created in the invitee's mailbox or other server component.

In some scenarios, when a non-owner invitee user declines or rejects the event invitation, or attempts to modify the event record data (e.g., changing the time or location), the user's client sends out an event message that is improperly asserted or interpreted as an event modification or cancellation request, as if the non-owner invitee were actually the owner of the event record. That is, the non-owner invitee asserts ownership privileges over the record resulting in the record being inadvertently modified or cancelled. This is often referred to as “hijacking” the event record from the owner. Record hijacking may occur unintentionally, or intentionally (e.g., a non-owner user intentionally generates an event message in an attempt to hijack the event record from the owner). In either case, the system does not accurately determine whether it was the owner or organizer of the event who sent out the update or cancellation request, and thus may honor unauthorized requests.

FIG. 1 is a block diagram of one example of a computing system record security architecture 100 configured to prevent record hijacking, regardless of whether the hijack attempts are intentional or unintentional. Before describing architecture 100 in further detail, it is noted that for the sake of illustration, but not by limitation, examples will be described herein in the context of event records (e.g., meeting records), and replicating or synchronizing the records between associated users (e.g., invitees) using email messages. However, this is by way of example only, other types of records and systems for communicating records to associated users are within the scope of the described subject matter.

Architecture 100 includes a computing system 102 that is accessible by one or more users through one or more user interface displays. In the illustrated example, users 104, 106, and 108 are illustrated accessing computing system 102 using respective client devices 110, 112, and 114. Client devices 110, 112, and 114 can be any of a wide variety of computing devices including, but not limited to, desktop computers, laptop computers, personal digital assistance, mobile phones, tablet computers, e-reader devices, etc. Further, a given user may access architecture 100 using a plurality of different user devices.

As illustrated, user 104 interacts with user interface display(s) 116 with user input mechanism(s) 118, user 106 interacts with user interface display(s) 120 having user input mechanism(s) 122, and user 108 interacts with user interface display(s) 124 having user input mechanism(s) 126. In FIG. 1, three users are illustrated interacting with computing system 102, for sake of illustration. However, in other examples, any number of users may interact with computing system 102. Further, computing system 102 may interact with other system(s) 128 used by other users.

Users 104, 106, and 108 can access computing system 102 locally or remotely. In the illustrated example, users 104, 106, and 108 use respective client devices that communicate with computing system 102 over a wide area network, such as the Internet. In one implementation, users 104, 106 and 108 utilize their client devices to store and retrieve data relative to “cloud-based” servers. In another example, components can be run at least partially from client devices 110, 112, and 114.

The users interact with the user input mechanisms in order to control and manipulate computing system 102. For example, using the user input mechanisms, the users can access data in a data store 130 and/or implement functionality of a record generation and processing system 132 and a messaging system 134.

User interface displays 116, 120 and 124 can be generated in any of a variety of different ways. In one example, computing system 102 includes a display system 136 having a user interface component 138, one or more sensors 140, and can include other components 142 as well. User interface component 138 is configured to generate user interface displays that are rendered on a client device, for a web browser or other interface. For instance, web pages can be requested, dynamically generated, and transmitted for rendering on the client devices. Sensor(s) 140 are configured to detect inputs to display system 136. In one example, systems 132 and 134 can include sensors configured to detect inputs to those systems.

In another example, one or more of client devices 110, 112, and 114 have client applications installed thereon to generate the respective user interface displays and detect inputs from the user.

User input mechanisms 118, 122, and 126 sense physical activities, for example by generating the user interface displays that are used to sense user interaction with computing system 102. The user interface displays can include user input mechanisms that sense user input in a wide variety of different ways, such as point and click devices (e.g., a computer mouse or track ball), a keyboard (either virtual or hardware) and/or a keypad. Where the user device used to display the user interface display is a touch-sensitive display, the inputs can be provided as touch gestures. Similarly, the user inputs can be provided by voice inputs or other natural user interface input mechanisms as well.

Computing system 102 also includes one or more communication interfaces 144, one or more processors 146, and can include other components 148 as well. Communication interface(s) are configured to communicate with client devices 110, 112, and 114, as well as other system(s) 128.

Processor(s) 146 comprises a computer processor with associated memory and timing circuitry (not shown). The processor is illustratively a functional part of system 102 and is activated by, and facilitates the functionality of, other systems, components and items in computing system 102.

While FIG. 1 shows a variety of different functional blocks, it will be noted that the blocks can be consolidated so that more functionality is performed by each block, or they can be divided so that their functionality is further distributed. It should also be noted that data store 130 can be any of a variety of different types of data stores. Further, data store 130 can be stored in multiple data stores. Also, the data store(s) can be local to the environments, agents, modules, and/or components that access them, or they can be remote therefrom and accessed by those environments, agents, modules and/or components. Similarly, some can be local while others are remote.

Computing system 102 can include applications that are executed using an application component that facilitates functionality within computing system 102. By way of example, an application component can access information in data store 130. For example, data store 130 can store data and metadata. The data and metadata can define workflows, processes, entities and a wide variety of other information. By way of example, entities stored in data store 130 can comprise or otherwise define items within computing system 102. For instance, entities in an enterprise system can include account entities that define various features of an account, customer entities that define various features of a customer, sales entities that define various features of sales that can occur during a sales process, and many other types of entities or objects. For instance, the entities can include or other define events, such as meetings. Further yet, entities can comprise documents, such as articles and emails, to name a few. The entities can be stored in data store 130 as records 150. Data store 130 can include user profiles 151, and can include other items 152 as well.

Record generation and processing system 132 is illustratively configured to generate and process records, such as records for meetings or other events. In one example, system 132 comprises one or more calendar servers.

System 132 includes a record generation component 154, a record modification component 156, a record owner identification component 158, a record security component 160, a display system controller 162, and can include other items 164 as well. Using display system controller 162, record generation component 154 can control display system 136 to generate and render user interface displays that receive record generation requests to generate records 150 in data store 130. For instance, through the user interface displays, user 104 defines a meeting event for which a record 150 is stored in data store 130.

FIG. 2 illustrates one example of a meeting record 200. Meeting record 200 comprises a plurality of fields 201 storing attributes for the meeting record including, but not limited to, a meeting title property 202, a date property 204, a time property 206, a location property 208, an owner or organizer email address (or ID) property 210, an owner or organizer unique identifier property 212, and associated users or invitees property 214, a description property 216, a meeting ID field 218 that uniquely identifies the meeting, and can include other properties 220 as well. Meeting record 200 can be stored in any suitable form including, but not limited to, a table.

Referring again to FIG. 1, record modification component 156 is configured to modify records 150 stored in data store 130. For instance, an owner of a given event record may issue a modification request to update the event record (e.g., cancel the event, change the location or time of the event, add additional recipients, etc.). Record owner identification component 158 is configured to identify the owner of a given record and record security component 160 is configured to enforce ownership or other privileges on records 150. For instance, record security component 160 includes a record hijack prevention component 166 that is configured to prevent record hijacking by unauthorized users. This is discussed in further detail below.

In the illustrated example, architecture 100 uses email (or other messaging) to replicate records for associated users (e.g., meeting invitees). As shown in FIG. 1, system 132 includes a record replication component 168 having a messaging system controller 170 configured to control messaging system 134. This is discussed in further detail below. Briefly, however, when a user (e.g., user 104) generates or modifies a record 150 using components 154 and/or 156, record replication component 168 operates to replicate that record for associated users. In the case of a event record having a set of invitees, messaging system controller 170 controls messaging system 134 to generate and send a message (i.e., an email in the present example) to each of the invitee users such that the record is replicated in those user's systems as well. It is noted that the invitee users can reside on the same system (e.g., the same email server) as the owner who generated the record or a different system or server (e.g., such as systems 128).

Messaging system 134 comprises, in one example, one or more email servers. As shown in FIG. 1, messaging system 134 includes a message generation component 172, a message processing component 174, one or more mailboxes 176, a display system controller 178, and can include other components 180 as well. Display system controller 178 is configured to control display system 136 to generate user interface displays that facilitate functionality for a user to create, edit, and send emails using component 172, as well as to view emails received in the user's mailbox 176. Message processing component 174 is configured to process messages received by messaging system 134, such as to parse an email to identify various properties and other data.

In the illustrated example, message generation component 172 includes a unique identifier generator 182 that uses an identifier generation algorithm 184 to generate unique identifiers for users of architecture 100. This is discussed in further detail below. In one example, the unique identifiers can be stored in user profiles 151.

As discussed above, in one example, systems 132 and 134 include calendar server(s) and email server(s) configured to perform various email processing and calendaring operations described herein. Although illustrated as separate components in FIG. 1, the calendar and email servers can be the same server or set of servers. A user may utilize a same account for managing both email and calendar data.

In the illustrated example of FIG. 1, architecture 100 generates and associates a unique identifier for each record 150 that identifies the owner of the record. In one example, record generation component 154 receives a record generation request that includes a set of attributes and generates a record 150 based on the request. For instance, an event record includes a set of attributes that define an event, such as a set of invitees. This set of attributes is stored in record 150 along with a unique identifier that uniquely identifies the user as the owner of the record. This unique identifier is utilized by component 160 to control and provide security with respect to subsequent event messages to prevent non-owner users from taking ownership of the record incorrectly, thereby hijacking the event record from the actual owner.

In one example, which is discussed in further detail below, the unique identifier can be provided as a property that is added to an email transport header of the event messages. The unique property is, in one example, a protected property which cannot be spoofed. Spoofing refers to a practice of forging source address and/or related message information to misrepresent an email identity. By changing the information, an individual can make an email message appear to originate from a trusted source when it in fact originates elsewhere.

FIG. 3 illustrates one example of an email header 300 having a set of fields 302. In one example, header 300 can be stored as a row in a header table, where the row includes a variety of information about the message in an account corresponding to a particular user. In the illustrated example, some or all fields 302 are controlled by the sending email server such that they cannot be set or spoofed by client devices 110, 112, and/or 114. That is, if client device 110, under the control of user 104, attempts to set the fields in header 300, message generation component 172 will overwrite these fields when sending messages to the associated users.

In the illustrated example, fields 302 includes a from field 304, a to field 306, a cc field 308, a subject field 310, a date field 312, a return path field 314, a unique identifier field 316, a message ID field 318, a verification value field 320, and can include other fields 322 as well. For sake of illustration, the from field 304 identifies the email address of the sender, the to field identifies the email address of the recipient, and the cc field identifies email addresses of any users that are “carbon copied” on the email. Subject field 310 includes the subject of the email, date field 312 includes a date when the email was sent, the return path field 314 identifies the path for sending a return email, and message ID field 318 provides a unique identifier for the message. In one example, message ID field 318 includes a system time and/or a sequence number.

Unique identifier field 316 comprises the unique identifier for the user for which the email is being sent. Field 316 thus comprises data obtained and stamped by the email server and is outside the control of an email sender who may be engaged in spoofing. Thus, even if a recipient of an email is able to view the transport header and identify the unique identifier in field 316, the recipient cannot use the unique identifier to hijack the meeting record because the recipient's email server will override this field of the email if the recipient attempts to spoof the unique identifier in a record hijack attempt.

In one example, the unique identifier comprises or is based in part on the user's email address (or ID). In another example, the unique identifier is different than and/or generated independent from the user's email address.

A user's email address may change over time, in some scenarios. For instance, a user of an organization may be given a new alias, for example if the user's name changes or they are given a different position. Further, email addresses are generally known by others and could be a target during a meeting hijack attempt. In one example, unique identifier generator 182 uses algorithm 184 to generate a unique identifier for the user that is immutable with respect to the user. As such, even if the user's mailbox 176 is moved or the user is assigned a new email address (e.g., the user's alias changes), the unique identifier of the user does not change.

In one particular example, the unique identifier generated by unique identifier generator 182 for user 104 is based on a unique identifier of the mailbox 176 assigned to user 104. For instance, a mailbox globally unique identifier (GUID) can be used. The mailbox GUID comprises a value set in computing system 102 when the mailbox is created, and remains the same for the lifetime of the mailbox. In other words, the mailbox GUID comprises a primary key for the mailbox, and is a unique value that distinguishes the individual mailbox from all other mailboxes. Alternatively, or in addition, the unique identifier generated by unique identifier generator 182 can be based on a unique object distinguished name that is defined when the mailbox is created.

In one particular example, the unique identifier comprises a plurality of attributes that have mutually exclusive situations in which the attributes can change. For instance, the unique identifier can comprise a combination of a first attribute (e.g., mailbox GUID) and a second attribute (e.g., unique object distinguished name that is assigned to the mailbox). As such, even if one of the attributes changes over time, the other attribute will not, thus resulting in the unique identifier remaining immutable with respect to the user.

These, of course, are examples of identifier generation algorithm 184. Any suitable unique identifiers can be utilized.

Referring again to FIG. 1, architecture 100 includes a verification component that is configured to ensure that the unique identifier of the sender in field 316 is valid and has not been modified prior to being received. For instance, the verification component is configured to detect if a user or system attempts to tamper with the unique identifier in field 316. For example, but not by limitation, the verification component can use encryption, a hash function, and/or check sum generation that uses a check sum function or algorithm that is known to the sending and receiving email servers.

In the illustrated example, message generation component 172 includes a verification value generator 186 and message processing component 174 includes a verification value analyzer 188. Verification value generator 186 is configured to generate a check sum or hash value based on some or all of the email header. For instance, the verification value can comprise a check sum generated on the unique identifier in field 316 of example email header 300. The verification value can be stored in verification value field 320 shown in FIG. 3.

Verification value analyzer 188 corresponds to generator 186 and is configured to determine whether the verification value in field 320 is valid and indicates that the unique identifier in field 316 is not erroneous and has not been tampered with.

FIG. 4 is a flow diagram illustrating one example of a method 400 for generating a record. For sake of illustration, but not by limitation, method 400 will be described in the context of generating an event record in architecture 100.

At block 402, record generation component 154 receives a record generation request from a first user (e.g., user 104). For example, in the request user 104 identifies email addresses of a set of event invitees (e.g., users 106, 108, and/or users of system(s) 128). The record comprises a meeting or other event having a set of event attributes 404, associated users (e.g., event invitees) 406, and can include other data 408 as well. Examples of event attributes include, but are not limited to, location, time, subject matter/topic information, etc. In one example, the event invitees are identified by their user email addresses selected by the first user in the record generation request.

At block 410, the method identifies the first user as the record owner (e.g., the event organizer) and, at block 412, unique identifier generator 182 generates a unique identifier of the record owner. In one example, the unique identifier is immutable and uniquely identifies the owner user (user 104 in the present example) from among all other users of architecture 100.

At block 414, record generation component 154 generates and stores the record with the event attributes 404 and the unique identifier generated at block 412.

At block 416, record replication component 168 replicates the records for each of the associated users (i.e., event invitees in the present example). In one example, for each invitee user, messaging system controller 170 controls messaging system 134 to generate an email comprising an event invitation for the invitee user. This is represented at block 418. The event invitation can include the event attributes 404 and/or associated users 406. At block 420, the unique identifier generated at block 412 is added to a protected header (or other portion) of the email. A verification value is generated based at least in part on the unique identifier. This is represented at block 422. At block 424, the verification value is added to the header (or other portion) of the email and the email is sent to the invitee user at block 426.

At block 428, the method determines whether the owner modifies the record. For example, the owner may decide to change the location or time of the event, cancel the event, and/or add invitees to the event. For instance, the owner may decide to forward the event to one or more additional users to be invited to the event.

If so, at block 430 the method verifies the owner by comparing the owner identifier to the event record. At block 432, the record is updated and blocks 416-426 can be repeated to replicate the updated record for the other users.

FIGS. 5-1 and 5-2 (collectively referred to as FIG. 5) are a flow diagram of one example of a method 500 for receiving and processing an event message. For sake of illustration, but not by limitation, method 500 will be described in the context of record security component 160 processing an email pertaining to an event in architecture 100.

At block 502, message processing component 174 receives an email (or other message) for a given user pertaining to an event. At block 504, the method determines whether the event record exists. If not, the event record is created in data store 130. This is represented by block 506. It is noted that the event creation at block 506 can be automatic. This is represented by block 508. Alternatively, the user can be prompted for confirmation of the event record creation. This is represented by block 510. At block 512, message processing component 174 parses the email to identify the unique identifier of the owner and the event attributes. In the example of FIG. 3, the unique identifier is obtained from field 316 which indicates the sender of the email for which the event record is created.

At block 514, the method can use a verification value provided in the email to verify the unique identifier upon which the unique identifier and attributes are stored in the event record. This is represented by block 516.

If the event record does exist at block 504, the method proceeds to block 518 in which the method determines whether the email comprises an event message asserting owner privileges. For instance, in one example the method determines whether the email purports to update the meeting attributes, or to cancel the meeting. If the event message does not assert owner privileges (e.g., it is simply an email message from an invitee with information about the event), the method proceeds to block 520 in which the email is delivered to the recipient.

At block 522, message processing component 174 parses the email to identify the unique identifier of the sender (e.g., field 316 in FIG. 3) and/or a verification value based on the unique identifier (e.g., field 320 in FIG. 3). The method uses the verification value to verify the unique identifier extracted from the email. This is represented by block 524. This verification can validate the unique identifier to ensure that it has not been corrupted or tampered with since the email message was generated from the sending email server.

At block 526, if the unique identifier is not verified, indicating that it is erroneous or corrupted, the method proceeds to block 528 which prevents the event message from modifying the event record. For instance, the email can be blocked or discarded. This is represented by block 530. In another example, the email is marked at out-of-date or already processed to prevent processing of the message against the event record. This is represented by block 532. Alternatively, or in addition, a non-delivery report (NDR) or “bounce” message can be sent to the sender of the email to indicate that it has not been processed at the recipient end. This is represented by block 534.

If the unique identifier is verified, the method proceeds to block 536 in which the event record is accessed. For example, the email received at block 502 can include a meeting identifier that is matched against a meeting ID field 218 for the corresponding record.

At block 538, the method determines whether the unique identifier extracted at block 522 corresponds to (e.g., matches) the unique identifier of the owner from the event record. If not, the method proceeds to block 528 to prevent the event message from modifying the event record.

If the unique identifier from the email corresponds to the event record, the method proceeds to block 540 in which the event message is processed to modify the event record. This can be done automatically, which is represented by block 542. Alternatively, or in addition, the recipient user can be prompted for confirmation as to whether the event message should be processed against the user's event record. This is represented by block 544.

FIG. 6 is a block diagram of one example of an architecture 600 in which users utilize different server systems. For example, user 104 uses client device 110 and user 108 uses client device 114 to access a server system 602. Server system 602 includes a calendar server 604 and an email server 606 which are, in one example, similar to systems 132 and 134 discussed above with respect to FIG. 1. A data store 608 stores event records 610 for users 104 and 108.

Server system 602 communicates with a server system 612 over a network 615, such as the Internet. Server system 612 is accessed by a user 614 using a client device 616 and user 618 using a client device 620. Server system 612 includes a calendar server 622 and an email server 624 which are, in one example, similar to systems 132 and 134 discussed above with respect to FIG. 1. A data store 626 stores event records 628 for users 614 and 618.

It can thus be seen that the present discussion provides significant technical advantages. For example, it provides a record security architecture that securely manages and controls record generation and modification to enforce ownership privileges over the records. The security architecture provides protection to prevent users from taking ownership of the records incorrectly, thereby hijacking the records to assert ownership privileges to which the users should not have access to. The architecture prevents users from being incorrectly recognized as the event organizer, or record owner, and validates meeting messages to prevent the messages from being processed against the event records if the meeting message is not coming from a legitimate owner of the record. This keeps the records secure while reducing or preventing inadvertent data loss, for example by preventing meetings from being erroneously cancelled or modified. Further yet, the architecture provides a framework to protect the transmission of the unique identifiers to prevent the identifier from being spoofed.

The present discussion has mentioned processors and servers. In one embodiment, the processors and servers include computer processors with associated memory and timing circuitry, not separately shown. They are functional parts of the systems or devices to which they belong and are activated by, and facilitate the functionality of the other components or items in those systems.

Also, a number of user interface displays have been discussed. They can take a wide variety of different forms and can have a wide variety of different user actuatable input mechanisms disposed thereon. For instance, the user actuatable input mechanisms can be text boxes, check boxes, icons, links, drop-down menus, search boxes, et cetera. They can also be actuated in a wide variety of different ways. For instance, they can be actuated using a point and click device (such as a track ball or mouse). They can be actuated using hardware buttons, switches, a joystick or keyboard, thumb switches or thumb pads, et cetera. They can also be actuated using a virtual keyboard or other virtual actuators. In addition, where the screen on which they are displayed is a touch sensitive screen, they can be actuated using touch gestures. Also, where the device that displays them has speech recognition components, they can be actuated using speech commands.

A number of data stores have also been discussed. It will be noted they can each be broken into multiple data stores. All can be local to the systems accessing them, all can be remote, or some can be local while others are remote. All of these configurations are contemplated herein.

Also, the figures show a number of blocks with functionality ascribed to each block. It will be noted that fewer blocks can be used so the functionality is performed by fewer components. Also, more blocks can be used with the functionality distributed among more components.

FIG. 7 is a block diagram of a cloud computing architecture 700. Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location or configuration of the system that delivers the services. In various embodiments, cloud computing delivers the services over a wide area network, such as the internet, using appropriate protocols. For instance, cloud computing providers deliver applications over a wide area network and they can be accessed through a web browser or any other computing component. Software or components of architecture 100 as well as the corresponding data, can be stored on servers at a remote location. The computing resources in a cloud computing environment can be consolidated at a remote data center location or they can be dispersed. Cloud computing infrastructures can deliver services through shared data centers, even though they appear as a single point of access for the user. Thus, the components and functions described herein can be provided from a service provider at a remote location using a cloud computing architecture. Alternatively, they can be provided from a conventional server, or they can be installed on client devices directly, or in other ways.

The description is intended to include both public cloud computing and private cloud computing. Cloud computing (both public and private) provides substantially seamless pooling of resources, as well as a reduced need to manage and configure underlying hardware infrastructure.

A public cloud is managed by a vendor and typically supports multiple consumers using the same infrastructure. Also, a public cloud, as opposed to a private cloud, can free up the end users from managing the hardware. A private cloud may be managed by the organization itself and the infrastructure is typically not shared with other organizations. The organization still maintains the hardware to some extent, such as installations and repairs, et cetera.

In the embodiment shown in FIG. 7, some items are similar to those shown in FIG. 1 and they are similarly numbered. FIG. 7 specifically shows that some or all components of architecture 100 are located in cloud 702 (which can be public, private, or a combination where portions are public while others are private). Therefore, user 704 (e.g., users 104, 106, and/or 108) uses a user device 706 (e.g., client devices 110, 112, and/or 114) to access those components through cloud 702.

FIG. 7 also depicts another embodiment of a cloud architecture. FIG. 7 shows that it is also contemplated that some elements of architecture 100 are disposed in cloud 702 while others are not. In one example, data store 130 can be disposed outside of cloud 702, and accessed through cloud 702. In another example, record generation and processing system 132 can be disposed outside of cloud 702, and accessed through cloud 702. In another example, messaging system 134 can be disposed outside of cloud 702, and accessed through cloud 702. In another example, display system 136 can be disposed outside of cloud 702, and accessed through cloud 702. In another example, at least some components of computing system 102 can be disposed on user device 706. This is represented by block 708. Regardless of where they are located, the elements of architecture 100 can be accessed directly by device 706, through a network (either a wide area network or a local area network), they can be hosted at a remote site by a service, or they can be provided as a service through a cloud or accessed by a connection service that resides in the cloud. All of these architectures are contemplated herein.

It will also be noted that architecture 100, or portions of it, can be disposed on a wide variety of different devices. Some of those devices include servers, desktop computers, laptop computers, tablet computers, or other mobile devices, such as palm top computers, cell phones, smart phones, multimedia players, personal digital assistants, et cetera.
