Abstract

A method and system for the secure distribution of content over a communications network such as the Internet where a content owner distributes content broken down into blocks to one or more content sources, the content sources serving as distribution points to subscribers, with the content owner retaining control over the distribution transaction. A subscriber requesting a content item from a content owner receives a list of content sources with available blocks of the content item in addition to the subscriber determining blocks available from peers on available peer-to-peer networks, and uses this information to determine a more optimal distribution of blocks of the content.

Claims

1. A method for secure distribution of a content item over a communications network, comprising:

packaging the content item into a plurality of blocks of data;

distributing at least one block of data from the plurality of blocks of data for the content item to at least one of a content source and a peer-to-peer network, wherein the at least one content source and peer-to-peer network serve as a distribution point for the block of data;

receiving a request from a subscriber for the content item, the content item made available over the communications network; and

providing to the subscriber a list identifying at least one content source, wherein the listed content source makes available to the subscriber at least one block of data for the content item.

2. The method according to claim 1, further comprising:

verifying an authorization for the subscriber to access the content item; and

providing to the subscriber a list identifying at least one content source as a function of verifying the authorization, wherein the listed content source makes available to the subscriber at least one block of data for the content item.

3. The method according to claim 1, wherein the block of data represents a portion of the content item broken down to facilitate distribution of the content item over the communications network.

4. The method according to claim 1, wherein the at least one block of data for the content item includes at least one metadata block, wherein the metadata block contains metadata for the content item.

5. The method according to claim 1, wherein the subscriber is a viewer process running on behalf of a content subscriber.

6. The method according to claim 1, wherein the provided list identifying at least one content source is prioritized geographically.

7. The method according to claim 6, wherein the provided list identifying at least one content source is prioritized geographically as a function of a subscriber location.

8. The method according to claim 1, wherein the provided list additionally includes load information for the at least content source.

9. A method for secure distribution of a content item over a communications network, comprising:

receiving from a content owner a block of data for the content item;

receiving from a subscriber a request for the block of data for the content item, the request automatically generated without a user interaction as a function of a prior request to a content owner for the content item;

adding an additional data item to the block of data for the content item as a function of the received request; and

sending the block of data to the subscriber as a function of the received request.

10. The method according to claim 9, further comprising:

verifying with the content owner an authorization for the subscriber to receive the block of data as a function of the received request.

11. The method according to claim 9, wherein the block of data represents a portion of the content item broken down to facilitate distribution of the content item over the communications network.

12. The method according to claim 9, wherein the subscriber is a viewer process running on behalf of a content subscriber.

13. The method according to claim 9, wherein the additional data item is a digital watermark item.

14. The method according to claim 9, wherein the request includes at least one of a public key and a subscriber item.

15. The method according to claim 14, further comprising:

encrypting the block of data as a function of the request.

16. A method for secure distribution of a content item over a communications network, comprising:

receiving from a content owner the content item;

dividing the content item into a plurality of blocks of data in order to facilitate the distribution of the content item over the communications network;

receiving from a subscriber a request for a block of data for the content item, the request automatically generated without a user interaction as a function of a prior request to the content owner for the content item;

adding an additional data item to the block of data for the content item as a function of the received request; and

sending the block of data to the subscriber as a function of the received request.

17. The method according to claim 16, further comprising:

verifying with the content owner an authorization for the subscriber to receive the block of data as a function of the received request.
