Personal location code
Methods and apparatus, including computer program products, for receiving a request from a requestor to locate a user. The request identifies a personal location code (PLC) for the user. It is determined if the request is allowed based on the PLC. If the request is allowed, the current location of the user is obtained based on the location of one or more devices associated with the user. The current location of the device is then provided to the requestor.
1. A method of controlling access to location information, comprising:
receiving, at a location server, a plurality of location requests to locate a target device, said plurality of location requests comprising a unique personal location code (PLC) that is distinct from identification information associated with a requesting device and distinct from identification information associated with said target device;
determining a validity of said PLC;
determining if said plurality of location requests exceed a predetermined number of location requests over a period of time;
obtaining a current location of said target device; and
providing said current location of said target device to said requesting device in response to a determination that said PLC is valid and that said plurality of location requests do not exceed said predetermined number of location requests over said period of time.
2. The method of controlling access to location information according to claim 1 , further comprising:
determining if said current location of said target device is private.
3. The method of controlling access to location information according to claim 1 , further comprising:
determining if said current location of said target device is in a set of approved locations.
4. The method of controlling access to location information according to claim 1 , further comprising:
determining if said unique received PLC has expired.
5. The method of controlling access to location information according to claim 1 , further comprising:
if said plurality of location requests is more than said predetermined number, alerting said target device.
6. The method of controlling access to location information according to claim 1 , further comprising:
limiting said current location of said target device to a predetermined granularity.
7. The method of controlling access to location information according to claim 1 , further comprising:
limiting said current location of said target device to a predetermined description.
8. The method of controlling access to location information according to claim 1 , further comprising:
at least one of charging and debiting an account associated with said unique received PLC for said request.
9. The method of controlling access to location information according to claim 1 , further comprising:
obtaining location for at least two target devices.
10. A method of controlling access to location information, comprising:
receiving, from a requesting device, a plurality of location requests comprising a unique personal location code (PLC), said received unique PLC being distinct from identification information associated with said requesting device and distinct from identification information associated with a target device;
sending said location request for a current location of said target device to a user device locator service; and
if said received unique PLC is determined to be a valid PLC and said plurality of location requests do not exceed a predetermined number over a period of time, providing location information associated with said target device to said requesting device.
11. The method of controlling access to location information according to claim 10 , further comprising:
tracking said current location of said target device over time.
12. The method of controlling access to location information according to claim 10 , further comprising:
tracking a time at said current location for said target device.
13. The method of controlling access to location information according to claim 10 , further comprising:
determining if said current location of said target device is private.
14. The method of controlling access to location information according to claim 10 , further comprising:
determining if said current location of said target device is in a set of approved locations.
15. The method of controlling access to location information according to claim 10 , further comprising:
determining if said unique received PLC has expired.
16. The method of controlling access to location information according to claim 10 , further comprising:
if said plurality of location requests is more than said predetermined maximum number, alerting said target device.
17. The method of controlling access to location information according to claim 10 , further comprising:
limiting said current location of said target device to a predetermined granularity.
