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

AMENDED CLAIMS received by the International Bureau on 31 JuI 2006 (31.07.06)
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, and wherein the message can be unscrambled by different sets of first and second keys.
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 pans 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 parry, 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 parry charge different amounts to the first and second recipients for access to the same message.
26
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 pans 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 pans 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.
18. An article of commerce that implements at least part of 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, such that sets of the keys will resolve to substantively different versions of the message.
19. The article of commerce of claim 18, further comprising a memory that stores the message of claim 1 according to the scrambled sequencing.
20. The article of commerce of claim 19, wherein the memory is read-only.
21. The article of commerce of claim 19, wherein the memory is non-volatile.
22. The article of commerce of claim 19, wherein the memory comprises a spinning media.

24. The article of commerce of claim 18, further comprising a telephony device that digitizes a voice as the message, and that transmits the scrambled multiple pans of the message.
25. The article of commerce of claim 23, wherein the telephony device uses an IP (Internet Protocol) technology to carry the scrambled multiple parts of the message.
26. The article of commerce of claim 18, further comprising a computer that receives the scrambled multiple parts of the message, uses the second key to de-scramble the message, and stores the message.
27. The article of commerce of claim 18, further comprising a device that receives the scrambled multiple pans of the message, uses the second key to de-scramble the message, and display the message as a moving image on a display screen.
28. The article of commerce of claim 19, wherein the device comprises a television.
29. The system of claim 18, wherein at least one of the multiple parts is encrypted.

38. The method of claim 37, wherein the different hosts are geographically separated from one another.
39. The method of claim 37, 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.
40. The method of claim 39, wherein the first and second keys are provided by a secure key management infrastructure.
41. The method of claim 40, wherein the secure key management infrastructure comprises a third party different from the first and second entities.
