Abstract

A system that incorporates teachings of the present disclosure may include, for example, a proxy system having a controller to submit to law enforcement agency an identity of a source that conceals its identity with one or more anonymous Internet Protocol addresses. Other embodiments are disclosed.

Claims

1. A method, comprising:

receiving from a law enforcement agency (LEA) an anonymous Internet Protocol (IP) address accompanied with a time stamp;

determining from the anonymous IP address and the time stamp at least one of an identity of the anonymous source and an IP address of customer premise equipment (CPE) used by the anonymous source to engage in Internet activities; and

submitting to the LEA at least one of the identity of the anonymous source and the IP address of the CPE used by the anonymous source.

2. The method of claim 1, wherein the LEA comprises an agency operating in conformance with the Communication Assistance for Law Enforcement Act (CALEA), and wherein the LEA detects the anonymous IP address from Internet activities of an anonymous source.

3. The method of claim 1, wherein the anonymous source is a subscriber of a privacy service that generates the anonymous IP address.

4. The method of claim 3, wherein the privacy service comprises a proxy system, wherein Internet traffic produced by the CPE is redirected to the proxy system utilizing the IP address assigned to the CPE by a network element of an Internet Service Provider (ISP) network from which the CPE operates, and wherein the proxy system creates the anonymous IP address to conceal the IP address of the CPE when the CPE communicates with third party devices.

5. The method of claim 1, wherein identity of the anonymous source comprises at least one of a name of the anonymous source, an address of the anonymous source, and an identity of an ISP network from which the CPE operates.

6. The method of claim 1, wherein the LEA utilizes the IP address of the CPE to monitor the CPE.

7. The method of claim 1, comprising enabling the LEA to monitor Internet traffic of the CPE responsive to receiving a request from the LEA.

8. The method of claim 1, comprising disabling the use of the anonymous IP address by the CPE responsive to receiving a request from the LEA.

9. The method of claim 1, comprising disabling subsequent generation of anonymous IP addresses for the CPE responsive to receiving a request from the LEA.

10. The method of claim 1, comprising selectively disabling generation of anonymous IP addresses for the CPE for establishing communications between the CPE and one or more websites identified in a request supplied by the LEA.

11. The method of claim 1, wherein the time stamp comprises at least one of a date, and time of day, wherein the CPE corresponds to a residential gateway, wherein the residential gateway operates in a media communication system, and wherein the media communication system corresponds to at least one of an ISP network, an Internet Protocol Television communication system, a cable TV communication system, a satellite TV communication system, a Public Switched Telephone Network, a Voice over IP (VoIP) communication system, and a IP Multimedia Subsystem combining the PSTN and VoIP communication systems.

12. The method of claim 1, comprising:

recording anonymous IP addresses used by the CPE and corresponding usage periods; and

comparing the anonymous IP address and time stamp supplied by the LEA to the recorded anonymous IP addresses and corresponding usage periods to identify the CPE and the IP address used by the CPE at a time when the anonymous IP address and corresponding time stamp is received from the LEA.

13. The method of claim 12, comprising determining the anonymous source from a subscriber database according to the identified CPE.

14. A computer-readable storage medium, comprising computer instructions for determining from an anonymous Internet Protocol (IP) address and a time stamp supplied by a law enforcement agency (LEA) at least one of an identity of an anonymous source and an IP address of customer premise equipment (CPE) used by the anonymous source to engage in concealed Internet activities.

15. The storage medium of claim 14, comprising computer instructions for submitting to the LEA the identity of the anonymous source and/or the IP address of the CPE responsive to receiving from the LEA an anonymous IP address and a time stamp indicating when the anonymous IP address was detected in use by the LEA.

16. The storage medium of claim 15, comprising computer instructions for:

recording anonymous IP addresses used by the CPE and corresponding usage periods; and

comparing the anonymous IP address and time stamp supplied by the LEA to the recorded anonymous IP addresses and corresponding usage periods to identify the CPE and the IP address used by the CPE at a time when the anonymous IP address and corresponding time stamp is received from the LEA.

17. The storage medium of claim 16, comprising computer instructions for determining the anonymous source from a subscriber database according to the identified CPE.

18. The storage medium of claim 14, wherein the computer-readable storage medium operates in a proxy system that conceals the identity of the CPE from third party devices.

19. The storage medium of claim 14, comprising computer instructions for enabling the LEA to monitor packet traffic of the CPE responsive to receiving a request from the LEA.

20. The storage medium of claim 14, comprising computer instructions for disabling subsequent generation of anonymous IP addresses for the CPE responsive to receiving a request from the LEA.

21. A proxy system, comprising a controller to submit to a law enforcement agency (LEA) an identity of a source that conceals its identity with one or more anonymous Internet Protocol (IP) addresses.

22. The proxy system of claim 21, wherein the identity comprises at least one of an IP address of a customer premise equipment (CPE) concealed with an anonymous IP address by the proxy system and a subscriber of services provided by the proxy system, and wherein the controller is adapted to conceal the identity of the source with assistance from a privacy unit that redirects Internet traffic of the CPE to the proxy system.

23. The proxy system of claim 21, wherein the controller is adapted to receive from the LEA an anonymous IP address and a time stamp indicating when the anonymous IP address was detected in use by the LEA to determine the identity of the source.

24. The proxy system of claim 23, wherein the controller is adapted to:

record the one or more anonymous IP addresses used by a CPE of the source and corresponding one or more usage periods; and

compare the anonymous IP address and time stamp supplied by the LEA to the recorded anonymous IP addresses and corresponding usage periods to identify the CPE.

25. The proxy system of claim 24, wherein the controller is adapted to identify a subscriber associated with the CPE from a subscriber database according to the identified CPE.
