Abstract

An anonymous location wireless network service for use in a wireless network. The service provides content providers with the location of network users without revealing their identities. The service includes a wireless network having a proxy server, a network communication link to a plurality of web sites, and a wireless communication link to a plurality of handheld devices. The proxy server blocks identity by reading the location and identity information of network devices, generating dummy identifications, relating the dummy identifications to the identity information, storing the relationships in a memory storage, and forwarding the location information and dummy identifications to the global computer network. Upon receiving messages from the global computer network, the proxy server reads the dummy identifications, looks up the related identification information in the memory storage, and forwards the data to the appropriate network devices.

Claims

1. A proxy server comprising:

at least one computer processor; and

at least one tangible computer-readable storage medium having instructions that, when executed by the at least one processor, cause the at least one processor to at least;

determine that each of multiple wireless devices is associated with a predetermined vicinity;

determine respective identification information corresponding to each of the wireless devices; and

associate the respective identification information corresponding to the wireless devices to a dummy identification in response to determining that each of the wireless devices is associated with the predetermined vicinity.

2. The proxy server of claim 1, wherein:

the multiple wireless devices, the dummy identification, and the predetermined vicinity are, respectively, first wireless devices, a first dummy identification, and a first predetermined vicinity; and

the instructions, when executed by the at least one processor, further cause the at least one processor to;

determine that each of multiple second wireless devices is associated with a second predetermined vicinity;

determine respective identification information corresponding to each of the second wireless devices; and

associate the respective identification information corresponding to the second wireless devices to a second dummy identification in response to determining that each of the second wireless devices is associated with the second predetermined vicinity.

3. The proxy server of claim 1, wherein the instructions, when executed by the at least one processor, further cause the at least one processor to:

receive a request from a requester relating to the predetermined vicinity; and

send the dummy identification to the requester in response to (i) receiving the request and (ii) determining that the wireless devices are associated with the predetermined vicinity.

4. The proxy server of claim 1, wherein the instructions, in causing the at least one processor to associate the respective identification information corresponding to the wireless devices to the dummy identification, cause the at least one processor to associate each of the wireless devices to the dummy identification, wherein the dummy identification is associated with the predetermined vicinity.

5. The proxy server of claim 1, wherein the instructions, when executed by the at least one processor, further cause the at least one processor to send, to a requester, the dummy identification and geographic information corresponding to the wireless devices.

6. The proxy server of claim 1, wherein the respective identification information corresponding to the wireless devices includes a distinct device identification corresponding to each of the multiple wireless devices.

7. The proxy server of claim 1, wherein:

associating the respective identification information to the dummy identification forms an association; and

the dummy identification cannot be used to send messages to the wireless devices without use of the association.

8. The proxy server of claim 1, wherein the dummy identification associated with the respective identification information for the multiple wireless devices is a single dummy identification.

9. A computer-implemented method, for providing a privacy service, comprising:

determining, at a tangible proxy server, that each of multiple wireless devices is associated with a predetermined vicinity;

determining, at the proxy server, respective identification information corresponding to each of the wireless devices; and

associating, at the proxy server, the respective identification information corresponding to the wireless devices to a dummy identification in response to determining that each of the wireless devices is associated with the predetermined vicinity.

10. The computer-implemented method of claim 9, wherein:

the multiple wireless devices, the dummy identification, and the predetermined vicinity are, respectively, first wireless devices, a first dummy identification, and a first predetermined vicinity; and

the method further comprises;

determining that each of multiple second wireless devices is associated with a second predetermined vicinity;

determine respective identification information corresponding to each of the second wireless devices; and

associate the respective identification information corresponding to the second wireless devices to a second dummy identification in response to determining that each of the second wireless devices is associated with the second predetermined vicinity.

11. The computer-implemented method of claim 10, wherein the respective identification information corresponding to the wireless devices includes a distinct device identification corresponding to each of the multiple wireless devices.

12. The computer-implemented method of claim 9, wherein:

associating the respective identification information to the dummy identification forms an association; and

the dummy identification cannot be used to send messages to the wireless devices without use of the association.

13. The computer-implemented method of claim 9, wherein the dummy identification associated with the respective identification information for the multiple wireless devices is a single dummy identification.

14. The computer-implemented method of claim 9, further comprising:

receiving a request from a requester relating to the predetermined vicinity; and

sending the dummy identification to the requester in response to (i) receiving the request and (ii) determining that the wireless devices are associated with the predetermined vicinity.

15. The computer-implemented method of claim 9, wherein associating the respective identification information corresponding to the wireless devices to the dummy identification includes associating each of the wireless devices to the dummy identification, wherein the dummy identification is associated with the predetermined vicinity.

16. The computer-implemented method of claim 9, further comprising sending, to a requester, the dummy identification and geographic information corresponding to the wireless devices.

17. A computer-implemented method, for providing a privacy service, comprising:

receiving, at a privacy-service system having at least one computer server, from a requester, a request regarding a pre-identified vicinity;

receiving, at the privacy-service system, identification information corresponding to a wireless device associated with the pre-identified vicinity; and

sending to the requester, from the privacy-service system, a dummy identification corresponding to the wireless device.

18. The computer-implemented method of claim 17, wherein the request seeks communication with a wireless device associated with the pre-identified vicinity.

19. The computer-implemented method of claim 17, further comprising:

determining, at the privacy-service system, location information indicating a location of the wireless device; and

determining, at the privacy-service system, that the wireless device is associated with the pre-identified vicinity using the location information.

20. The computer-implemented method of claim 17, further comprising:

determining, at the privacy-service system, that a privacy setting relating to the wireless device is set to allow communication of location information corresponding to the wireless device and disallow communication of the identification information; and

the privacy-service system, in response to determining that the privacy setting is set to disallow communication of the identification information, associating the identification information to the dummy identification, in a memory, to form a stored association between the identification information and the dummy identification.
