Abstract

A cable lock apparatus that is operated by the computer equipment that the apparatus is intended to protect, rather than by a key, is disclosed. According to a preferred embodiment of the invention, the cable lock is equipped with a hot-swappable computer interface, such as a Universal Serial Bus (USB) interface, for connecting to the computer. The user of the computer unlocks the cable lock by providing a password or other form of authentication to the computer. The computer transmits this authentication information, via the USB interface, to circuitry within the cable lock device, which validates the authentication information. If the authentication information validates properly, the cable lock device circuitry activates a motor or solenoid to mechanically release the cable lock.

Claims

1. A method comprising:

receiving authentication information from an information handling system;

validating the received authentication information with respect to information stored within non-volatile storage contained within a cable lock apparatus; and

in response to a determination that the received authentication information authenticates a user of the information handling system that is authorized to unlock the cable lock apparatus, unlocking the cable lock apparatus.

2. The method of claim 1, wherein the authentication information is a password.

3. The method of claim 1, wherein unlocking the cable lock apparatus includes releasing a padlock associated with the cable lock apparatus.

4. The method of claim 1, wherein the authentication information is received via a universal serial bus (USB) interface.

5. The method of claim 1, wherein unlocking the cable lock apparatus includes releasing the cable lock apparatus from the information handling system.

6. The method of claim 1, wherein the information handling system is selected from the group consisting of a mobile computer, a desktop computer, a personal digital assistant device, and a handheld computer.

7. A method comprising:

unlocking a cable lock apparatus, the steps for unlocking including;

establishing a connection between a computer and embedded electronics contained within the cable lock apparatus; and

providing authentication information to the computer for transmission to the embedded electronics, wherein the embedded electronics directs a mechanism within the cable lock apparatus to unlock the cable lock apparatus in response to a determination that the authentication information can be validated by the embedded electronics.

8. The method of claim 7, wherein establishing the connection includes attaching an electrical connector associated with the cable lock apparatus to the computer.

9. The method of claim 7, wherein the connection is administered according to a hot-swappable device interface specification.

10. The method of claim 9, wherein the hot-swappable device interface specification is a Universal Serial Bus (USB) interface specification.

11. A method comprising:

unlocking a cable lock apparatus, the steps for unlocking including;

establishing a connection between a computer and embedded electronics contained within the cable lock apparatus, wherein the connection is established via a hot-swappable interface; and

in response to the connection being established, providing authentication information to the computer for transmission to the embedded electronics, wherein the embedded electronics directs a mechanism within the cable lock apparatus to unlock the cable lock apparatus in response to a determination that the authentication information can be validated by the embedded electronics.

12. A program product comprising:

computer operable medium having computer readable code, the computer readable code being effective to;

receive authentication information from a computer;

validate the received authentication information with respect to information stored within non-volatile storage contained within a cable lock apparatus; and

in response to a determination that the received authentication information authenticates a user of the computer that is authorized to unlock the cable lock apparatus, unlock the cable lock apparatus.

13. The program product of claim 12, wherein the authentication information is a password.

14. The program product of claim 12, wherein the code that unlocks the cable lock apparatus includes code effective to release a padlock associated with the cable lock apparatus.

15. The program product of claim 12, wherein the authentication information is received via a universal serial bus (USB) interface.

16. An apparatus comprising:

an interface, wherein the interface allows for reception of authentication data from an information handling system;

validation circuitry, wherein the validation circuitry includes an authenticator which authenticates data received through the interface and determines whether a user of the information handling system is authorized to unlock a cable lock apparatus that locks the information handling system; and

an electromechanical lock mechanism that, when directed by the validation circuitry, releases the cable lock apparatus from a locked state.

17. The apparatus of claim 16, wherein the validation circuitry includes a programmable processor.

18. The apparatus of claim 16, wherein the electromechanical lock mechanism includes a solenoid that, when activated, causes a pin to retract.

19. The apparatus of claim 16, wherein the interface is a hot-swappable interface.

20. The apparatus of claim 19, wherein the hot-swappable interface is a Universal Serial Bus (USB) interface.

21. The apparatus of claim 16, wherein the electromechanical lock mechanism rotates a rotational lock component when directed by the validation circuitry.

22. The apparatus of claim 16, wherein the interface is configured to supply power from the information handling system to power at least one of the validation circuitry and the electromechanical lock mechanism.

23. The apparatus of claim 16 further comprising:

a second interface, wherein the second interface is configured to allow an additional peripheral to be connected through the second interface and first interface to the information handling system.

24. An apparatus comprising:

a hot-swappable computer interface, wherein the hot-swappable computer interface allows for reception of authentication data from an information handling system and the hot-swappable computer interface provides power to a cable lock apparatus;

validation circuitry, wherein the validation circuitry includes an authenticator which authenticates data received through the interface and determines whether a user of the information handling system is authorized to unlock a cable lock apparatus that locks the information handling system; and

an electromechanical lock mechanism that, when directed by the validation circuitry, releases the cable lock apparatus from a locked state.

25. An apparatus comprising:

an information handling system that includes;

one or more processors;

a memory accessible by the processors;

a power supply that provides power to the processors; and

a housing that stores the processors and the power supply; and

a cable lock that locks the information handling system, the cable lock including;

a computer interface, wherein the computer interface allows for reception of authentication data from the information handling system;

validation circuitry, wherein the validation circuitry includes an authenticator which authenticates data received through the interface and determines whether a user of the information handling system is authorized to unlock a cable lock apparatus that locks the information handling system; and

an electromechanical lock mechanism that, when directed by the validation circuitry, releases the cable lock from a locked state.
