发明名称 System, method, and apparatus for securely providing content viewable on a secure device
摘要 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, or over a network, or 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.
