Abstract

An anonymous communication module that provides full conversational anonymous messaging and voice/video communication between two or more parties interacting over a wireless/landline network. An anonymous messaging module accepts an anonymous initiation message to a public address to trigger the start of an anonymous voice/video conversation between a message originator and a message recipient. An anonymous communication module performs intercept and address substitution on a message and/or voice/video call transmitted between two or more parties via an anonymous communication service. The anonymous communication module substitutes a real address in the source field of an intercepted message and/or voice/video call, with an anonymous address mapped to that real address, and substitutes an anonymous address in the destination field of an intercepted message and/or voice/video call with a real address mapped to that anonymous address. The anonymous communication module then forwards the newly formatted message and/or voice/video call to an intended message/call destination.

Claims

1. Apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another, comprising:

an anonymous digital voice communication module to form a digital packet gateway between said at least two actively interacting digital voice communication devices, said anonymous digital voice communication module anonymizing said active two-way digital packet voice communication by substituting for a real address in source fields of digital packets associated with said active interaction passing therethrough with an anonymous address, and substituting for an anonymous address in destination fields of digital packets associated with said active interaction passing therethrough with an affiliated real address, before forwarding said intercepted digital packet voice communication to an intended destination associated with said real address;

wherein anonymity is maintained between said at least two digital voice communication devices vis-à

-vis each other.

2. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said real address comprises:

a mobile directory number.

3. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said real address comprises:

an Internet Protocol (IP) address.

4. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said digital packet voice communication comprises:

Voice over Internet Protocol (VoIP).

5. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said digital packet voice communication comprises:

video.

6. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said digital packet voice communication comprises:

a short message.

7. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said digital packet voice communication comprises:

a multimedia message (MMS).

8. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, wherein said digital packet voice communication comprises:

an instant message (IM).

9. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 1, further comprising:

an internal address mapping database to affiliate real addresses to at least one anonymous address, for each of said at least two digital voice communication devices.

10. The apparatus to anonymize at least two digital voice communication devices actively interacting in two-way digital packet voice communication with one another according to claim 9, wherein:

said anonymous digital voice communication module intercepts said digital packet corresponding to said active two-way digital packet voice communication;

queries said internal address mapping database to determine said anonymous source address to substitute in for said real source address supplied in said digital packet, queries said internal address mapping database to determine said real destination address to substitute in for said anonymous destination address supplied in said digital packet, and forwards a newly, anonymously-addressed digital packet to an intended destination digital voice communication device.

11. A method of providing full conversational anonymous voice communication between two or more digital voice communication devices, comprising:

intercepting an anonymously addressed digital voice packet transmitted between two or more digital voice communication devices;

substituting for a real source address associated with said digital voice packet with an anonymous source address, in said intercepted digital voice packet;

substituting for an anonymous destination address associated with said intercepted digital voice packet in a destination address field of said intercepted digital voice packet with a real destination address for an intended destination digital voice communication device; and

forwarding said intercepted digital voice packet to said intended destination.

12. The method of providing full conversational anonymous voice communication between two or more digital voice communication devices according to claim 11, further comprising:

querying an internal address mapping database to affiliate said real destination address with said anonymous destination address; and

querying said internal address mapping database to affiliate said real source address with said anonymous source address.
