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. An agent resident in a portable electronic device, the agent configured to:

communicate with a remote server; and

send information relating to the identification of said portable electronic device;

wherein a communication between the server and the agent is unapparent to a user of the portable electronic device, and

wherein said information permits the determination at the server as to whether said portable electronic device is reported lost or stolen.

2. The agent as in claim 1 resident in a location normally inaccessible to an operating system of the portable electronic device.

3. The agent according to claim 1 configured to permit otherwise normal operation of the portable electronic device.

4. The agent according to claim 1 configured to communicate with the server at spaced-apart intervals.

5. The agent according to claim 1 configured to send local time and/or date to the remote server.

6. The agent according to claim 1 configured to:

run in small increments in order not to noticeably slow operation of the portable electronic device;

hook into a timer routine of a processor in said portable electronic device; and

/or

access an interrupt request line of a processor in said portable electronic device.

7. The agent according to claim 1 comprising:

a first computer readable program code embodied in a first one of a plurality of computer readable media in the portable electronic device, said first computer readable program code adapted to be loaded into RAM in the portable electronic device and executed by a processor in the portable electronic device to initiate communication with the remote computer and send information to the remote computer relating to the identification of said portable electronic device; and

a second computer readable program code embodied in a second one of said plurality of computer readable media, said second computer readable program code adapted to be executed by the processor to check the RAM for a signature relating to the first computer readable program, said second computer readable program code being further adapted to be executed by the processor to install a copy of said first computer readable program code in said first one of said plurality of computer readable media.

8. The agent according to claim 1, wherein said portable electronic device is connectable to a telecommunications system and said telecommunications system is connected to a remote computer, the agent configured to:

check availability of at least one communication port;

initiate communication with the remote computer through an available one of said at least one communication port; and

prepare the portable electronic device to transmit unique location information to the remote computer.

9. The agent according to claim 1 connectable bi-directionally to the remote computer, the agent further configured to:

receive a string of data containing at least one instruction from the remote computer; and

take at least one action in response to said at least one instruction.

10. The agent according to claim 1, wherein the portable electronic device also includes a backup agent.

11. A method for monitoring or tracing a portable electronic device having an agent, comprising:

a. the agent communicating with a remote server;

b. the agent sending information relating in part to the location of said portable electronic device to said server; and

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

12. The method of claim 11 wherein,

the agent initiates the communication, and

the information permits determination at the server as to whether the portable electronic device is lost or stolen.
