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 method comprising:

receiving, at a system comprising a processor, a request regarding a targeted area, the request being received from a requester;

receiving, by the system, identification information corresponding to a wireless device located within the targeted area;

determining, by the system, that a preference associated with the wireless device indicates that the identification information associated with the wireless device is not to be shared; and

sending, by the system and to the requester, a dummy identification corresponding to the wireless device.

2. The method of claim 1, wherein the request comprises a request seeking communication with a wireless device associated with the targeted area.

3. The method of claim 1, further comprising:

determining, by the system, location information indicating a location of the wireless device; and

determining, by the system, that the wireless device is located within the targeted area based upon the location information.

4. The method of claim 1, further comprising:

associating, by the system, the identification information with the dummy identification to form a stored association between the identification information and the dummy identification.

5. The method of claim 4, wherein receiving the request comprises receiving a plurality of requests associated with a plurality of wireless devices located within the targeted area.

6. The method of claim 5, wherein receiving identification information comprises receiving identification information for each of the plurality of wireless devices.

7. The method of claim 6, wherein associating the identification information with the dummy identification comprises associating the identification information for each of the plurality of wireless devices in a single dummy identification.

8. The method of claim 1, wherein the wireless device comprises a first wireless device, wherein the dummy identification comprises a first dummy identification, and wherein the targeted area comprises a first targeted area.

9. The method of claim 8, further comprising:

receiving, by the system, second identification information corresponding to a second wireless device associated with a second targeted area; and

associating, by the system, the second identification information with a second dummy identification in response to determining that the second wireless device is associated with the second targeted area.

10. The method of claim 1, further comprising:

receiving, by the system, a further request from a further requester, the further request relating to the targeted area; and

sending, by the system, the dummy identification to the further requester in response to receiving the further request.

11. The method of claim 1, wherein the dummy identification is associated with the targeted area.

12. A method comprising:

receiving, at a proxy server comprising a processor, a request for information relating to a targeted area, the request being received from a requester;

receiving, by the proxy server, identification information corresponding to a wireless device located within the targeted area;

determining, by the proxy server, that a preference associated with the wireless device indicates that the identification information associated with the wireless device is not to be shared; and

sending, by the proxy server and to the requester, a dummy identification corresponding to the wireless device.

13. The method of claim 12, further comprising:

determining, by the proxy server, location information indicating a location of the wireless device; and

determining, by the proxy server, that the wireless device is associated with the targeted area based upon the location information.

14. The method of claim 12, further comprising:

associating, by the proxy server, the identification information with the dummy identification to form a stored association between the identification information and the dummy identification.

15. The method of claim 14, wherein receiving the request comprises receiving a plurality of requests associated with plurality of wireless devices located within the targeted area, wherein receiving identification information comprises receiving identification information for each of the plurality of wireless devices, and wherein associating the identification information with the dummy identification comprises associating the identification information for each of the plurality of wireless devices in a single dummy identification.

16. The method of claim 12, wherein the wireless device comprises a first wireless device, wherein the dummy identification comprises a first dummy identification, and wherein the targeted area comprises a first targeted area.

17. The method of claim 16, further comprising:

receiving, by the proxy server, second identification information corresponding to a second wireless device associated with a second targeted area; and

associating, by the proxy server, the second identification information with a second dummy identification in response to determining that the second wireless device is associated with the second targeted area.

18. A method comprising:

receiving, at a system comprising a processor, a request regarding a pre-identified vicinity, the request being received from a requester;

receiving, by the system, identification information corresponding to a wireless device associated with the pre-identified vicinity;

determining, by the system, location information indicating a location of the wireless device;

determining, by the system, that a privacy setting associated with the wireless device is set to disallow communication of identification information associated with the wireless device;

in response to determining that the privacy setting is set to disallow the communication of the identification information, associating, by the system, the location information with a dummy identification; and

sending, by the system and to the requester, the dummy identification corresponding to the wireless device.

19. The method of claim 18, wherein determining that the privacy setting is set to disallow communication further comprises determining that the privacy setting is set to allow communication of the location information.

20. The method of claim 18, wherein the wireless device comprises a cellular telephone.
