Abstract: Technologies are disclosed to transfer responsibility and control over security from player makers to content authors by enabling integration of security logic and content. An exemplary optical disc carries an encrypted digital video title combined with data processing operations that implement the title's security policies and decryption processes. Player devices include a processing environment (e.g., a real-time virtual machine), which plays content by interpreting its processing operations. Players also provide procedure calls to enable content code to load data from media, perform network communications, determine playback environment configurations, access secure nonvolatile storage, submit data to CODECs for output, and/or perform cryptographic operations. Content can insert forensic watermarks in decoded output for tracing pirate copies.

Abstract: A method and system to digitally sign a content license associated with content, and to distribute content via a network in a geographically controlled manner, commences when a content requestor requests delivery of the encrypted content. A content delivery system performs a content to determine a geographic location associated with the content requestor. The content requestor authorization process may also determine geographic access criteria associated with the content, and whether the geographic location complies with the geographic access criteria. The content delivery system will release the content for delivery to the content requestor if the content location complies with the geographic access criteria.
