Abstract

There is provided a method and system to enforce delay of access to encrypted digital content. The system includes a receiving module to receive a request for digital content and register a request time responsive to the receiving the request for digital content. The request for digital content includes a digital content identifier that identifies encrypted digital content. Next, a content distribution module communicates digital content information based on the request for digital content. The digital content information includes the encrypted digital content. Finally a license distribution module communicates a license that delays access to the encrypted digital content based on the request time.

Claims

1. A system to enforce delay of access to encrypted digital content, the system including:

a license distribution module to communicate a license that delays access to the encrypted digital content based on the request time.

2. The system of claim 1, wherein the license is utilized by a decryption engine to ignore a request to decrypt the encrypted digital content.

3. The system of claim 1, wherein the license is utilized by a decryption engine to grant a request to decrypt the encrypted digital content.

4. The system of claim 3, wherein the license includes a decryption delay time that is added to the request time to enforce the delay of access to the encrypted digital content.

5. A system to enforce delay of access to encrypted digital content, the system including:

a receiving module to receive a request for digital content and register a request time responsive to receiving the request for digital content, the request for digital content including a digital content identifier that identifies the encrypted digital content;

a content distribution module to communicate digital content information based on the request for digital content, the digital content information including the encrypted digital content; and

a license distribution module to communicate a license that enables decryption of the encrypted digital content, the license distribution module to delay the communication of the license, based on the request time, to delay access to the encrypted digital content.

6. The system of claim 5, wherein the license distribution module is to delay the communication of the license for a license delay time after the request time.

7. The system of claim 5, wherein the encrypted digital content includes any one of a group of encrypted digital content including video digital content, multimedia digital content, and audio digital content.

8. The system of claim 5, wherein the digital content information includes a plurality of encrypted digital content that are respectively associated with a plurality of licenses that delay decryption of the respective encrypted digital content.

9. The system of claim 5, wherein the encrypted digital content is associated with policy information that requires that an advertisement be played.

10. The system of claim 9, wherein the advertisement includes any one of a group including a commercial presentation, a public announcement, and a legal warning.

11. A system to enforce delay of access to unencrypted digital content, the system including:

a receiving module to receive a request for digital content and to register a request time responsive to the receiving the request for digital content, the request for digital content including a digital content identifier that identifies the unencrypted digital content; and

a content distribution module to communicate the unencrypted digital content, the content distribution module to delay communication of the unencrypted digital content, based on the request time, to delay access to the unencrypted digital content.

12. The system of claim 11, wherein the content distribution module delays the communication of the unencrypted digital content for a content delay time after the request time.

13. The system of claim 12, further including an advertisement distribution module to communicate an advertisement responsive to receipt of the request for digital content and before the content distribution module is to communicate the unencrypted digital content.

14. The system of claim 12, wherein the advertisement includes any one of a group including a commercial presentation, a public announcement, and a legal warning.

15. A method to enforce delay of access to encrypted digital content, the method including:

receiving a request for digital content that includes a digital content identifier that identifies the encrypted digital content;

registering a request time responsive to the receiving the request for digital content;

communicating digital content information based on the request for digital content, the digital content information including the encrypted digital content; and

communicating a license that delays access to the encrypted digital content based on the request time.

16. The method of claim 15, wherein the license is utilized by a decryption engine to ignore a request to decrypt the encrypted digital content.

17. The method of claim 15, wherein the license is utilized by a decryption engine to grant a request to decrypt the encrypted digital content.

18. The method of claim 17, wherein the license includes a decryption delay time that is added to the request time.

19. A method to enforce delay of access to encrypted digital content, the method including:

receiving a request for digital content that includes a digital content identifier that identifies the encrypted digital content;

registering a request time responsive to receiving the request for digital content;

communicating digital content information based on the request for digital content, the digital content information including the encrypted digital content; and

communicating a license that enables decryption of the encrypted digital content, the communicating the license delayed, based on the request time, to delay access to the encrypted digital content.

20. The method of claim 19, wherein the communicating the license is delayed for a license delay time after the request time.

21. The method of claim 19, wherein the encrypted digital content includes any one of a group of encrypted digital content including video digital content, multimedia digital content, and audio digital content.

22. The method of claim 19, wherein the encrypted digital content information includes a plurality of encrypted digital content that are respectively associated with a plurality of licenses that delay decryption of the respective encrypted digital content.

23. The method of claim 19, wherein the encrypted digital content is associated with policy information that requires that an advertisement be played.

24. The method of claim 23, wherein the advertisement includes any one of a group including a commercial presentation, a public announcement, and a legal warning.

25. A method to enforce delay of access to unencrypted digital content, the method including:

receiving a request for digital content that includes a digital content identifier that identifies the unencrypted digital content;

registering a request time responsive to the receiving the request for digital content; and

communicating the unencrypted digital content, the communication of the unencrypted digital content delayed, based on the request time, to delay access to the unencrypted digital content.

26. The method of claim 25, wherein the communicating the unencrypted digital content is delayed for a content delay time after the request time.

27. The method of claim 26, further including communicating an advertisement responsive to receipt of the request for unencrypted digital content and before the communicating the unencrypted digital content.

28. The method of claim 26, wherein the advertisement includes any one of a group including a commercial presentation, a public announcement, and a legal warning.

29. A tangible machine readable medium storing a set of instructions that, when executed by a machine, cause the machine to:

receive a request for digital content and register a request time responsive to the receipt of the request for digital content, the request for digital content including a digital content identifier that identifies encrypted digital content;

communicate digital content information based on the request for digital content, the digital content information including the encrypted digital content; and
