Abstract

An encryption system, method, and computer program product are provided. After the receipt of encrypted content, a plurality of coordinates associated with a location of a device are identified. In use, the content is decrypted utilizing the coordinates.

Claims

1. A method, comprising:

receiving encrypted content;

identifying a plurality of coordinates associated with a location of a device; and

decrypting the content utilizing the coordinates.

2. The method of claim 1, wherein the coordinates are identified utilizing at least one of a global positioning system and tri angulation.

3. The method of claim 1, wherein the device includes a set-top box.

4. The method of claim 3, wherein the set top box is adapted for receiving content via a satellite content, provider.

5. The method of claim 3, wherein the set top box is adapted for receiving content via a content provider.

6. The method of claim 1, wherein the coordinates are encrypted.

7. The method of claim 1, wherein an acceptable range of current coordinates is generated based on the coordinates.

8. The method of claim 7, wherein the acceptable range of current coordinates is based on a predetermined amount of error.

9. The method of claim 7, wherein the acceptable range of current coordinates is compared with predetermined coordinates.

10. The method of claim 9, wherein the predetermined coordinates are determined during registration of the device.

11. The method of claim 9, wherein the predetermined coordinates are stored in a look-up table.

12. The method of claim 9, wherein the predetermined coordinates are stored in read-only memory.

13. The method of claim 9, wherein a key is enabled based on the comparison.

14. The method of claim 13, wherein the encrypted content is decrypted utilizing the key.

15. The method of claim 1, wherein the content is encrypted utilizing a key.

16. The method of claim 1, wherein a key is included with the encrypted content, and the content is decrypted utilizing the coordinates and the key.

17. A method, comprising:

identifying and communicating a plurality of coordinates associated with a location of a device; and

encrypting content utilizing the coordinates.

18. A system, comprising:

a processor for identifying a plurality of coordinates associated with a location of a device, and decrypting content utilizing the coordinates.

19. The system of claim 18, wherein the processor is coupled to memory via a bus.

20. The system of claim 18, wherein the processor is a component of a set top box.
