Abstract

A system for automatically locating a personal electronic object is described. The system comprises: a communicator; a location sensor; and a security controller. The security controller activates the location sensor to determine a location of the personal electronic object. When security of the system is compromised and access to a computer network or a wireless network is available, the location is transmitted through the communicator.

6. The device as recited in claim 4 wherein said storage device includes an erase device, the security controller operable to cause the erase device to erase data on the storage device.

7. The device as recited in claim 6 wherein the security controller causes the erase device to erase data in response to a signal from a remote location.

8. The device as recited in claim 1 wherein said stimulus is a remote trigger.

9. The device as recited in claim 1 wherein said stimulus is responsive to a physical tamper sensor.

10. The device as recited in claim 1 wherein said stimulus is responsive to an improper response by a user.

11. The device as recited in claim 1 wherein at least one of said at least two location sensors is selected at random.

12. The device as recited in claim 1 wherein at least one of said at least two wireless communicators is selected at random.

13. A method for automatically locating a personal electronic object comprising the steps of:

providing the personal electronic object with at least two location sensors and at least two wireless communicators;

detecting a security stimulus;

determining a location of the personal electronic object with at least one of said at least two location sensors; and

communicating said location of the personal electronic object with at least one of said at least two wireless communicators.

14. The method as recited in claim 13 wherein at least one of said at least two wireless communicators is a network interface.

15. The method as recited in claim 13 wherein the step of determining a location utilizes a global positioning system.

16. The method as recited in claim 13 further comprising the step of storing a series of locations of the personal electronic object wherein movement of the personal electronic object is tracked.

17. The method as recited in claim 16 wherein the step of communicating includes transmitting said series of locations of the personal electronic object.

18. The method as recited in claim 13 wherein said security stimulus is derived from a remote trigger.

19. The method as recited in claim 13 wherein said security stimulus is derived from a physical tamper sensor.

20. The method as recited in claim 13 wherein said security stimulus is derived from an improper response by a user.

21. The method as recited in claim 13 further comprising the step of randomly selecting a location sensor to determine said location.

22. The method as recited in claim 13 further comprising the step of randomly selecting a communicator before communicating.

23. The method as recited in claim 13 further comprising the step of randomly selecting an antenna before communicating.

24. A system for automatically locating a personal electronic object, said object having at least two global positioning system receivers and at least two wireless communication interfaces, the system comprising:

a stimulus sensor; and

a security controller;

wherein said security controller, in response to a signal from said stimulus sensor, utilizes at least one of said global positioning system receivers to determine a location of the personal electronic object and manages transmission of the location through at least one of said at least two wireless communication interfaces.

25. The system as recited in claim 24 further comprising a storage device for recording a series of locations of the personal electronic object wherein movement of the personal electronic object may be tracked.

26. The system as recited in claim 25 wherein said security controller transmits said series of locations of the personal electronic object through at least one of said at least two wireless communication interfaces.

27. The device as recited in claim 25 wherein said storage device includes an erase device, the security controller operable to cause the erase device to erase data on the storage device.

28. The device as recited in claim 27 wherein the security controller causes the erase device to erase data in response to a signal from a remote location.

29. The system as recited in claim 24 wherein said stimulus sensor detects a remote trigger.

30. The system as recited in claim 24 wherein said stimulus sensor detects physical tampering with the personal electronic object.
