Abstract

A method for locating an electronic device such as a stolen portable computer. The method includes initiating a phone call; receiving automatic number identification (ANI) information; and terminating the phone call before the call is answered. The received ANI information may then be provided to law enforcement agencies so that they may retrieve the electronic device. The act of initiating and terminating may be performed by a computer or a modem.

Claims

1. A method, performed by an electronic device at a first location, for enabling an owner to determine the location of the electronic device in response to a detected attempt to circumvent security measures incorporated into the electronic device, the method comprising:

initiating a phone call to a target location via a communication network providing automatic number identification (ANI) information without alerting a user of the electronic device;

maintaining the phone call for a predetermined period of time only sufficient to allow the communication network to transmit to the target location ANI information identifying the first location; and

terminating the phone call in response to the expiration of the predetermined period of time.

2. The method of claim 1 wherein the act of initiating includes dialing a phone number of the owner.

3. The method of claim 2 further comprising updating the owner phone number only if a predetermined password is provided.

4. The method of claim 2 further comprising updating the owner phone number only if a predetermined password is provided, wherein the owner phone number is stored on a computer program storage device by a computer manufacturer.

5. The method of claim 1 wherein the acts of initiating, maintaining, and terminating are repeated at random time intervals.

6. The method of claim 1 wherein the acts of initiating, maintaining, and terminating are repeated at constant time intervals.

7. The method of claim 1 wherein the act of initiating occurs upon detection of an act selected from the following acts:

(a) formatting a hard disk drive of the electronic device,

(b) modifying CMOS memory of the electronic device, and

(c) receiving an incorrect password associated with the electronic device.

8. The method of claim 1 wherein the act of initiating without alerting the user comprises muting a speaker on the electronic device.

9. The method of claim 1 wherein the act of initiating includes dialing at least one of a long distance phone number and a local phone number.

10. The method of claim 1 wherein the act of initiating and the act of terminating are performed by a modem.

11. A program storage device storing instructions that when executed by an electronic device at a first location, enables an owner to determine the location of the electronic device in response to a detected attempt to circumvent security measures incorporated into the electronic device by performing a method comprising:

initiating a phone call to a target location via a communication network providing automatic number identification (ANI) information without alerting a user of the electronic device;

maintaining the phone call for a predetermined period of time only sufficient to allow the communication network to transmit to the target location ANI information identifying the first location; and

terminating the phone call in response to the expiration of the predetermined period of time.

12. The program storage device of claim 11 wherein the acts of initiating, maintaining, and terminating are repeated at random time intervals.

13. The program storage device of claim 11 wherein the acts of initiating, maintaining, and terminating are repeated at constant time intervals.

14. The program storage device of claim 11 wherein the act on initiating occurs upon detection of an act selected from the following acts:

(a) formatting a hard disk drive of the electronic device;

(b) modifying CMOS memory of the electronic device; and

(c) receiving an incorrect password associated with the electronic device.

15. A computer containing the program storage device of claim 11.

16. A modem containing the program storage device of claim 11.

17. The program storage device of claim 11, wherein the act of initiating includes dialing a phone number of the owner.

18. The program storage device of claim 17, wherein the method further comprises updating the owner phone number only if a predetermined password is provided.

19. The program storage device of claim 17, wherein the method further comprises updating the owner phone number only if a predetermined password is provided, and the owner phone number is stored on a computer program storage device by a computer manufacturer.

20. The program storage device of claim 11, wherein the act of initiating without alerting the user comprises muting a speaker on the electronic device.

21. The program storage device of claim 11, wherein the act of initiating includes dialing at least one of a long distance phone number and a local phone number.

22. The program storage device of claim 11, wherein the act of initiating and the act of terminating are performed by a modem.
