Abstract

Apparatuses and methods for facilitating anonymous messaging via a wireless network, directed to protection of information relating to a sender node. According to the disclosed apparatuses and methods, a node sending a message to one or more recipient nodes is provided with the option to conceal its identity, or at least a portion of its addressing information, from at least one recipient of the message. In order to provide compliance with applicable protocols, the sender may be assigned a temporary identifier for the purpose of transmitting the message to the recipient.

Claims

1. A method for sending an anonymous message from a first node to a second node, comprising:

receiving from the first node a first message addressed to the second node;

determining, based on privacy data, whether the first message is to be sent to the second node anonymously; and

if the first message is to be sent to the second node anonymously, generating a second message to the second node comprising at least a portion of the first message and having a sender identifier matching a temporary identifier.

2. The method as set forth in claim 1 further comprising:

associating the temporary identifier with the first node;

receiving from the second node a third message in response to the second message;

identifying a node associated with the sender identifier for the second message; and

forwarding the third message to the node associated with the sender identifier for the second message.

3. The method as set forth in claim 1 wherein the message containing privacy configuration data includes at least one of an activation instruction, a deactivation instruction, a modify instruction and an interrogate instruction.

4. The method as set forth in claim 1 wherein the message containing privacy configuration data includes a uniform resource identifier (URI).

5. The method as set forth in claim 4 wherein the uniform resource identifier is a Session Initiation Protocol (SIP) URI.

6. The method as set forth in claim 4 wherein the uniform resource identifier is a Telephone network (Tel) URI.

7. The method as set forth in claim 1 wherein the first node and the second node employ incompatible messaging protocols.

8. The method as set forth in claim 1 wherein the temporary identifier is retrieved from a database.

9. An application server configured to send an anonymous message from a first node to a second node, comprising:

a component configured to receive from the first node a request to conceal the identity of the first node;

a component configured to receive from the first node a first message addressed to the second node;

a component configured to determine, based on the request to conceal, whether the first message is to be sent to the second node anonymously; and

a component configured to generate a second message to the second node comprising at least a portion of the first message and having a sender identifier matching a temporary identifier if the first message is to be sent to the second node anonymously.

10. The application server as set forth in claim 9 further comprising:

a component configured to associate the temporary identifier with the first node;

a component configured to receive from the second node a third message in response to the second message;

a component configured to identify a node associated with the sender identifier for the second message; and

a component configured to forward the third message to the node associated with the sender identifier for the second message.

11. The application server as set forth in claim 9 wherein the message containing privacy configuration data includes at least one of an activation instruction, a deactivation instruction, a modify instruction and an interrogate instruction.

12. The application server as set forth in claim 9 wherein the message containing privacy configuration data includes a uniform resource identifier (URI).

13. The application server as set forth in claim 12 wherein the uniform resource identifier is a Session Initiation Protocol (SIP) URI.

14. The application server as set forth in claim 12 wherein the uniform resource identifier is a Telephone network (Tel) URI.

15. The application server as set forth in claim 9 wherein the first node and the second node employ incompatible messaging protocols.

16. The application server as set forth in claim 9 wherein the temporary identifier is retrieved from a database.

17. A user equipment device operable to configure a remote node for anonymous messaging, comprising:

a component configured to receive from a user privacy configuration data for outgoing messages from the user equipment device to external nodes;

a component configured to store the privacy configuration data for outgoing messages; and

a component configured to transmit to a remote application server a message containing the privacy configuration data for outgoing messages, wherein the configuration data is operable to instruct the application server to remove at least one identifier for the user equipment device from at least one outgoing message.

18. The user equipment device as recited in claim 17, further comprising a component configured to receive settings data from the application server.

19. The user equipment device as recited in claim 17, wherein the configuration data includes a uniform resource identifier (URI).

20. The user equipment device as recited in claim 19, wherein the URI is a SIP URI.

21. The user equipment device as recited in claim 19, wherein the URI is a Tel.URI.

22. The user equipment device as recited in claim 17, wherein the message to the application server contains at least one of an activate instruction, a deactivate instruction, a modify instruction or an interrogate instruction.

23. A method for sending an anonymous message from a first node to a second node, comprising:

receiving from the first node a first message addressed to the second node in a first messaging system, the message including data identifying the first node;

determining, based on a privacy tag setting in the first message, whether anonymous messaging is to be invoked;

if anonymous messaging is to be invoked, substituting the data identifying the first node with a temporary identifier; and

sending a second message to the second node using a second messaging system whereby the originating users identity cannot be derived by inspection.
