Abstract

A cryptographic system splits a digital message into multiple parts, and scrambles sequencing of the multiple parts according to an algorithm requiring first and second keys to resolve. The keys can be related by a graphically recognizable mathematical formula, and can be implemented by a third party or other secure key management infrastructure, and can support pay-per-play subscription models. Scrambled messages can be stored on a CD, DVD or other memory, with the multiple parts being distributed on different storage hosts. Contemplated messages include digitized video or other movies, books, music, or any other type of information. Messages can be split according to color separations, video and audio tracts, frequency ranges, or in any other manner. Splitting of the message into the multiple parts can be used as a fingerprint in identifying a creator of the message.

Claims

1. A method of storing and retrieving data, comprising:

utilizing a cryptographic system to split a digital message into multiple parts, which are then stored on different hosts; and

using the cryptographic system to resolve locations and sequencing of the multiple parts of the message.

2. The method of claim 1, wherein the different hosts are geographically separated from one another.

3. The method of claim 1, wherein a first entity initiates storage of the message on the different hosts, and a second entity different from the first entity utilizes first and second keys to determine resolve the locations and sequencing of the multiple parts of the message.

4. The method of claim 3, wherein the first and second keys are provided by a secure key management infrastructure.

5. The method of claim 4, wherein the secure key management infrastructure comprises a third party different from the first and second entities.

6. The method of claim 1, wherein the message comprises a movie.

7. The method of claim 1, wherein the message comprises a book.

8. The method of claim 1, wherein the message comprises a music tract.

9. The method of claim 1, wherein the message is split into the multiple parts according to color separations.

10. The method of claim 1, wherein the message is split into the multiple parts according to video and audio tracts.

11. The method of claim 1, wherein the message is split into the multiple parts according to different frequency ranges.

12. The method of claim 1, further comprising using the splitting of the digital message into the multiple parts as a fingerprint in identifying a creator of the message.

13. The method of claim 1, further comprising storing different versions of the message using different scrambling first keys, providing different playback hosts with different de-scrambling keys, and transmitting the different versions of the message to the different playback hosts.
