Abstract

A system for locating and monitoring electronic devices utilizing a security system that is secretly and transparently embedded within the computer. This security system causes the client computer to periodically and conditionally call a host system to report its serial number via an encoded series of dialed numbers. A host monitoring system receives calls from various clients and determines which calls to accept and which to reject by comparing the decoded client serial numbers with a predefined and updated list of numbers corresponding to reported stolen computers. The host also concurrently obtains the caller ID of the calling client to determine the physical location of the client computer. The caller ID and the serial number are subsequently transmitted to a notifying station in order to facilitate the recovery of the stolen device. The security system remains hidden from the user, and actively resists attempts to disable it.

Claims

1. A method for monitoring a portable electronic device having a location, comprising:

determining in a monitoring computer that communication to a portable electronic device should be established;

preparing a message in the monitoring computer;

sending the message from the monitoring computer to the portable electronic device;

silently and invisibly receiving the message in the portable electronic device, wherein the portable electronic device performs a security action based on the message;

the monitoring computer receiving, from the portable electronic device, information indicating the location of the portable electronic device; and

the monitoring computer sending said information to one or more of an email inbox, a mobile telephone, a pager and a fax machine.

2. The method of claim 1, further comprising the monitoring computer awaiting establishment of the communication between the monitoring computer and the portable electronic device before sending the message.

3. The method of claim 1, further comprising the monitoring computer initiating a session to communicate with the portable electronic device.

4. The method of claim 1, wherein the monitoring computer determines that the communication should be established if the portable electronic device has been reported to the monitoring computer as being lost or stolen.

5. The method of claim 1, wherein the monitoring computer establishes the communication.

6. The method of claim 1, wherein:

the communication comprises multiple partial communications that are made intermittently, and

the monitoring computer controls one or more of a period of intermittency and a time of establishment of the multiple partial communications.

7. The method of claim 1, wherein the monitoring computer requests establishment of a communication.

8. A server for monitoring portable electronic devices, configured to:

determine that communication should be established with a portable electronic device;

prepare a security message for the portable electronic device if the portable electronic device has been reported to the server as being lost or stolen; and

send the security message to the portable electronic device in a communication that is unapparent to a user of the portable electronic device.

9. The server according to claim 8, further configured to ascertain whether or not the portable electronic device has been reported lost or stolen by accessing a flag corresponding to the portable electronic device.

10. The server according to claim 9, further configured to:

set the flag to indicate whether or not the portable electronic device is lost or stolen; and

set further flags corresponding to further portable electronic devices to indicate whether each of the further portable electronic devices are lost or stolen.

11. The server according to claim 10, wherein each set flag is a serial number of a corresponding lost or stolen portable electronic device in a list of lost or stolen portable electronic devices, and wherein the server is configured to ascertain whether or not the portable electronic device is lost or stolen by comparing a serial number of the portable electronic device with serial numbers in the list.

12. The server according to claim 9, configured to set a secondary flag for the portable electronic device indicating that the portable electronic device has communicated with the server after being reported as lost or stolen.

13. The server according to claim 8, configured to:

receive, from the portable electronic device, unique location information related to the portable electronic device; and

send the unique location information to one or more of an email inbox, a mobile telephone, a pager and a fax machine.

14. The server according to claim 8, configured to:

accept a communication initiated by an agent in the portable electronic device, said communication comprising unique location information related to the portable electronic device; and

send the unique location information to one or more of an email inbox, a mobile telephone, a pager and a fax machine.

15. The server according to claim 8, wherein the communication uses a dedicated communication line between the portable electronic device and the server.

16. The server according to claim 8, configured to receive a serial number of the portable electronic device while communicating with the portable electronic device.

17. The server according to claim 8, configured to communicate with the portable electronic device via one or more of a wire, a wireless medium, a satellite, a cable and a modem.

18. The server according to claim 8, configured to record one or more of date and time of the communication, said date and time being local to the portable electronic device.

19. The server according to claim 8, configured to:

communicate with the portable electronic device using repeated, intermittent, partial communications, and

control one or more of a period of intermittency and a time of establishment of the partial communications.

20. A server for monitoring portable electronic devices, configured to:

determine that a communication should be established with a portable electronic device;

communicate with the portable electronic device in a communication that is unapparent to a user of the portable electronic device;

ascertain whether or not the portable electronic device has been lost or stolen by accessing a flag corresponding to the portable electronic device;

prepare a security message for the portable electronic device if it is lost or stolen; and

send the security message to the portable electronic device.
