Recipient address masking in computer communications

Abstract

A messaging system for masking addresses from sending processes. The messaging system maintains a message service profile and a service-address profile. The messaging system accesses recipient data. Sending processes are able to send messages to the messaging system in a form such that each message has an message type and list of recipients. The messaging system is able to determine which of a set of sending services is to be used to send the message, based on the message-service profile. The service-address profile stores information about where in the structure of recipient data the appropriate address for the selected service is located. The addresses corresponding to the named recipients, for the services determined by the messaging system, can be retrieved by from recipient data. The message system can then provide the recipient address to the appropriate sending services to send the message.

Description

FIELD OF THE INVENTION

[0001] The present invention is directed to an improvement in computing systems and in particular to an improvement in sending messages to recipients using address masking.

BACKGROUND OF THE INVENTION

[0002] In computer systems, and particularly in e-commerce environments, it is typical that messages are sent to recipients using different potential sending services. For example messages may be sent by email, fax or other electronic gateways available to a sending system. Typically a system sending a message to a recipient has available to it the message to be sent, the recipient name, the sending service to be used and the address for the recipient to be utilized by the sending service. Thus where a sending system is forwarding a fax the recipients name and fax name will be used and a fax service called by the sending system to have the message sent to the recipient.

[0003] It is also known to interpose a messaging system between a sending system and the sending services. Such a messaging system will potentially automate the management of messages being sent using sending services.

[0004] With such systems, there is a potentially significant overhead for the sending system in maintaining information concerning the address of the recipient and the preferred method of receiving messages from the sending service. Similarly there is a potentially costly overhead involved in the sending system supporting new communication methods. For example where a secure electronic communications link is added to a system the sending system will require modification to support such a communication service.

[0005] It is therefore desirable to have a messaging system that is able to permit messages to be sent without the sender process specifying the service to be used for the message. It is also desirable to have a messaging system to permit new services to be added without requiring modifications to the sender process.

BRIEF DESCRIPTION OF THE DRAWINGS

[0036] FIG. 1 is a block diagram showing components of the messaging system of the preferred embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0037] FIG. 1 shows in a block diagram view components of the messaging system of the preferred embodiment. sender processes 10 are shown in FIG. 1 as being representative of different sending systems, or a single sending system that generate messages to be forwarded to recipients. Recipient data 12 is a collection of data that matches recipient name or identifier with recipient addresses. Messaging system 14 is shown containing message-service profile data 16 and service-address profile data 18. Also shown in FIG. 1 is a collection of sending services 20 comprising example fax service 22, email service 24 and a service denoted other service 26. Administrator 28 is also shown in FIG. 1.

[0038] In the preferred embodiment, sender processes 10 do not maintain information as to which sending service is to be used for forwarding a message, or the addresses to which messages are to be sent. Each one of sender processes 10 is able to generate messages to be sent to one or more recipients. In the preferred embodiment, a sender process will simply pass messaging system 14 the message and the names of the intended recipients. No address or method of delivering the message necessarily specified by sender processes 10. In the preferred embodiment, messaging system 14 arranges for the appropriate sending service to be used and the correct address for the recipients to be included with the message to be sent by one of sending services 20. The recipient address for the message is masked from sender processes 10.

[0039] Addresses for recipients are, however, maintained within the system of the preferred embodiment. FIG. 1 shows recipient data 12 as being a separate database. Recipient data may be created and maintained using different processes. For example, administrator 28 may directly maintain the data. Users may be given access to the data also to add or update information. In an e-commerce environment, applications run from a web server may manage the recipient data, based on browser input. Recipient data 12 is intended to include recipient names and addresses for the recipients for the appropriate different sending services.

[0040] It will be understood that a recipient name is typically the name of a person or organization but in certain circumstances can be an identifier that has meaning in the context of the system. For example, the preferred embodiment may be implemented for internal communications in a company where all messaging is sent based on employee number. In the description of the invention, name or identifier may be used to express data signifying a particular message recipient.

[0041] Messaging system 14 includes message-service profile 16. In the preferred embodiment, this data is created and maintained by administrator 28 using tools provided in messaging system 14. Message-service profile 16 maintains data to specify a sending service or services for a message. In the preferred embodiment, messages are defined to have types and message-service profile 16 associates sending services with those types. For example, a message may be defined to be an order type or an invoice type. The sending service used will potentially differ based on the type of the message.

[0042] It is also possible, however, for message-service profile 16 to be a sophisticated combination of preferences for the selection of sending services, based on recipient name and/or message or sending services characteristics. For example, urgent messages to particular recipients may be sent by both fax service 22 and email service 24 whereas confidential messages may be sent using other services 26.

[0043] Messaging system 14 also includes service-address profile 18. This profile specifies, for each sending service in sending services 20, where in recipient data 12 the appropriate address for the sending service wilt be found,

[0044] In operation, after sender processes 10 sends a message with designated type and intended recipients to messaging system 14, message-service profile 16 is accessed. Messaging system 14 in this way determines which sending services 20 are to be utilized for forwarding the message to the recipients. In the preferred embodiment, the sending service selected is based on a the message type for the message to be sent. Message service profile 16 is accessed to look up which sending service (or services) is specified for the message type in question.

[0045] Service address profile 18 is then accessed to determine where in recipient data 12 the appropriate address is located for the sending service to be used. For example, where recipient data 12 is a database of records having fields, service-address profile 18 will indicate which field contains addresses used by a given one of sending services 20. Service-address profile 18 maintains a link between the sending service and the location of an address within the structure of recipient data 12.

[0046] Once the appropriate link to recipient data 12 has been obtained from service-address profile 18, messaging system 14 accesses recipient data 12 to obtain the address (or addresses) for the recipient (or recipients) corresponding to the sending services to be used. The message is then sent from messaging system 14 to the appropriate sending service in sending services 20, with the address retrieved. Where there are multiple recipients or multiple services to be used, messaging system 14 ensures that the services are accessed to provide for communication of all messages to all recipients in the appropriate manner.

[0047] The maintenance of the system of the preferred embodiment benefits from the architecture described above. A new sending service may be added to sending services 20 without requiring changes to sender processes 10. Where a new sending service is added to sending services 20 administrator 28 will update message service profile 26, as appropriate. Service address profile 18 will be changed to add a new link to recipient data 12, indicating the location of the appropriate address in the structure of recipient data 12. The sender process functionality remains as previously defined, messages are forwarded to messaging system 14 with the type and the indicated recipients. The inclusion of the new sending service, and the addresses required for the new service, are masked from sender processes 10.

[0048] Although a preferred embodiment of the present invention has been described here in detail, it will be appreciated by those skilled in the art that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
