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 cryptographic system that 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.

2. The system of claim 1, wherein the message includes digitized video data.

3. The system of claim 1, wherein at least one of the multiple parts is encrypted.

4. The system of claim 1, wherein the first key varies across the multiple parts of the message.

5. The system of claim 1, wherein the first and second keys are related according to a graphically recognizable mathematical formula.

6. The system of claim 5, wherein the formula defines a triangle.

7. The system of claim 1, wherein the first and second keys are provided by a secure key management infrastructure.

8. The system of claim 7, wherein the message is sent from a first party to a second party, and the secure key management infrastructure comprises a third party.

9. The system of claim 8 wherein at least one of a sender of the message and the third party charges a fee for providing at least some aspect of the secure key management infrastructure.

10. The system of claim 8 wherein at least one of a sender of the message and the third party limits access to the message using a pay per play subscription model.

11. The system of claim 8 wherein a sender broadcasts the message in scrambled format to first and second recipients, and at least one of the sender and the third party charge different amounts to the first and second recipients for access to the same message.

12. The system of claim 1, wherein the first key is a public key and the second key is a private keys.

13. The system of claim 1, wherein a first portion of the system is implemented as software on a sending computer, and the sending computer transmits the multiple parts of the message in a scrambled sequence.

14. The system of claim 13, wherein the sending computer embeds the message with information that instruct specific tests or processes at the recipient.

15. The system of claim 13, the sending computer transmits the multiple parts of the message using a virtual private network technology.

16. The system of claim 13, wherein a second portion of the system is implemented as software on a recipient'"'"'s computer.

17. The system of claim 16, wherein the software on the recipient'"'"'s computer authenticates the message.
