Abstract: Method and devices are directed to uniquely identifying content in a highly distributed content delivery system such that an origin of unauthorized content use may be more accurately determined. Content received from a content owner is distributed to a persistent security database and a key manager, which manages encryption and decryption keys for content that may be already encrypted. Decrypted content is fingerprinted or watermarked by a fingerprinter/watermarker module such that a recipient of content is identifiable, and saved in a separate database. Information about fingerprinted/watermarked content may be reported back to content owner for tracking purposes. A key wrap module wraps and attaches aggregator's encryption key to the content before it is transmitted to downstream service operators or users.

Abstract: A system, apparatus, and method are directed to providing and securely viewing secure content. In one embodiment, a secure player provides secure screening/previewing of secure content, such as a motion picture, by a member of an awards organization. A content key is employed to selectively encrypt at least a portion of a content stream. The content key is encrypted with a screener key. The encrypted content key is embedded into the secure content. The screener key is encrypted using public/private key pair that is bound to the secure player. The secure content may be distributed on a medium, such as a DVD, high definition DVD, and the like. The secure player is configured to receive the medium, screener key, and a screener identity. The screener identity and screener key are employed by the secure player to decrypt and enable secure viewing of the content.

Abstract: A system and method for providing end-to-end security of content over a heterogeneous distribution chain is provided. A content owner provides content to an aggregator that receives the content and processes the content. The processing may involve decrypting the content and associating at least one of a unique fingerprint and a watermark to the decrypted content. The unique fingerprint and a watermark to the decrypted content provide identifying characteristics to the content. Additional content-based fingerprints may be used to monitor quality of consumer experience for Video and Audio. The content may be sent in a decrypted state to a client or in an encrypted state. When the content is encrypted the aggregator wraps and encrypts the content with a signature such that an end-to-end flow of the content may be determined. Application Level encryption is used to provide network/distribution medium transparency as well as persistent encryption.
