Abstract

Systems and methods are described for performing policy-managed, peer-to-peer service orchestration in a manner that supports the formation of self-organizing service networks that enable rich media experiences. In one embodiment, services are distributed across peer-to-peer communicating nodes, and each node provides message routing and orchestration using a message pump and workflow collator. Distributed policy management of service interfaces helps to provide trust and security, supporting commercial exchange of value. Peer-to-peer messaging and workflow collation allow services to be dynamically created from a heterogeneous set of primitive services. The shared resources are services of many different types, using different service interface bindings beyond those typically supported in a web service deployments built on UDDI, SOAP, and WSDL. In a preferred embodiment, a media services framework is provided that enables nodes to find one another, interact, exchange value, and cooperate across tiers of networks from WANs to PANs.

Claims

1. A system comprising:

means for encrypting a piece of electronic content;

means for associating a license with the piece of electronic content, the license comprising a control program, the control program requiring, as a condition of authorizing decryption of the piece of electronic content, possession of a set of one or more link objects logically connecting a first node object with a second node object, the license further comprising an encrypted version of a first key for use in decrypting the piece of electronic content;

means for sending the piece of electronic content to a remote computer system;

means for determining that the remote computer system has possession of a set of one or more link objects logically connecting the first node object with the second node object, wherein at least one of the one or more link objects comprises an encrypted version of a second key for use in decrypting the first key;

means for decrypting the second key using a key associated with the remote computer system;

means for decrypting the first key using the second key; and

means for decrypting the piece of electronic content using the first key.

2. The system of claim 1, in which the license further comprises a controller object securely binding the control program with the first key.

3. The system of claim 2, in which the controller object include a hash of a content key object and a control object, wherein the content key object comprises an encrypted version of the first key, and the control object comprises the control program.

4. A computer-readable medium comprising program code, the program code being operable, when executed by a computer system, to cause the computer system to perform actions comprising:

encrypting a piece of electronic content;

associating a license with the piece of electronic content, the license comprising a control program, the control program requiring, as a condition of authorizing decryption of the piece of electronic content, possession of a set of one or more link objects logically connecting a first node object with a second node object, the license further comprising an encrypted version of a first key for use in decrypting the piece of electronic content;

sending the piece of electronic content to a remote computer system;
