Abstract

A system for tracking the location of electronic devices and prohibiting unauthorized operation thereof includes a control unit, configured for wireless communication with an electronic device, the electronic device having a basic input/output system (BIOS) associated therewith. The control unit is configured to remotely disable the electronic device in the event the electronic device is detected to be beyond a programmed radius for a programmed duration, in accordance with a specifically defined level of security, wherein the extent to which the electronic device is disabled by the control unit is dependent upon the specifically defined level of security.

Claims

1. A system for tracking the location of electronic devices and prohibiting unauthorized operation thereof, comprising:

a control unit, configured for wireless communication with an electronic device, the electronic device having a basic input/output system (BIOS) associated therewith;

the control unit configured to remotely disable the electronic device in the event the electronic device is detected to be beyond a programmed radius for a programmed duration, in accordance with a specifically defined level of security;

wherein the extent to which the electronic device is disabled by the control unit is dependent upon the specifically defined level of security.

2. The system of claim 1, wherein the control unit is configured for both temporary disablement and permanent disablement of the electronic device.

3. The system of claim 2, wherein:

the control unit is configured for a first level of security in which the electronic device is temporarily disabled by encryption of the device BIOS and data stored thereon;

the control unit is configured for a second level of security in which the electronic device is temporarily disabled by overwriting of the device BIOS and data stored thereon;

the control unit is configured for a third level of security in which the electronic device is disabled by blowing of selected electrically programmable fuses of the device BIOS and circuitry therein, wherein operation of the electronic device is capable of being restored at least once after disablement thereof, and

the control unit is configured for a fourth level of security in which the electronic device is permanently disabled by blowing of selected electrically programmable fuses of the device BIOS and circuitry therein.

4. The system of claim 3, wherein the control unit is further configured to restore operation of the electronic device disabled in accordance with the first level of security by transmission of an encryption key thereto.

5. The system of claim 3, wherein the control unit is further configured to restore operation of the electronic device disabled in accordance with the second level of security by reloading the device BIOS and data stored thereon from a stored location.

6. The system of claim 3, wherein the control unit is further configured to operation of the electronic device disabled in accordance with the third level of security by blowing of additionally selected electrically programmable fuses of the device BIOS and circuitry therein.

7. The system of claim 3, wherein the electronic device is configured for disablement according to one of the levels of security, notwithstanding a previous disablement executed according to another of the levels of security immediately prior thereto.

8. The system of claim 3, wherein the control unit is configured to transmit a signal to activate one or more alarm indicators on the electronic device whenever the device is no longer within the programmed proximity and/or whenever the electronic device ceases to send proximity signals back to the control unit.

9. A method for tracking the location of electronic devices and prohibiting unauthorized operation thereof, the method comprising:

programming a control unit to remotely disable an electronic device in wireless communication therewith, in the event the electronic device is detected to be beyond a programmed radius for a programmed duration, in accordance with a specifically defined level of security, the electronic device having a basic input/output system (BIOS) associated therewith;

wherein the extent to which the electronic device is disabled by the control unit is dependent upon the specifically defined level of security.

10. The method of claim 9, wherein the control unit is configured for both temporary disablement and permanent disablement of the electronic device.

11. The method of claim 10, further comprising:

inputting a first set of tracking parameters into the control unit so as to implement a first level of security in which the electronic device is temporarily disabled by encryption of the device BIOS and data stored thereon;

inputting a second set of tracking parameters into the control unit so as to implement a second level of security in which the electronic device is temporarily disabled by overwriting of the device BIOS and data stored thereon;

inputting a third set of tracking parameters into the control unit so as to implement a third level of security in which the electronic device is disabled by blowing of selected electrically programmable fuses of the device BIOS and circuitry therein, wherein operation of the electronic device is capable of being restored at least once after disablement thereof, and

inputting a fourth set of tracking parameters into the control unit so as to implement a fourth level of security in which the electronic device is permanently disabled by blowing of selected electrically programmable fuses of the device BIOS and circuitry therein.

12. The method of claim 11, wherein the control unit is further configured to restore operation of the electronic device disabled in accordance with the first level of security by transmission of an encryption key thereto.

13. The method of claim 11, wherein the control unit is further configured to restore operation of the electronic device disabled in accordance with the second level of security by reloading the device BIOS and data stored thereon from a stored location.

14. The method of claim 11, wherein the control unit is further configured to operation of the electronic device disabled in accordance with the third level of security by blowing of additionally selected electrically programmable fuses of the device BIOS and circuitry therein.

15. The method of claim 11, wherein the electronic device is configured for disablement according to one of the levels of security, notwithstanding a previous disablement executed according to another of the levels of security immediately prior thereto.

16. The method of claim 11, further comprising transmitting a signal from the control unit to activate one or more alarm indicators on the electronic device whenever the device is no longer within the programmed proximity and/or whenever the electronic device ceases to send proximity signals back to the control unit.
