摘要

A method for digital content protection comprises generating a plurality of frame keys, retrieving a plurality of frames from digital content, and at least one of encrypting and decrypting the digital content with a different frame key that dynamically changes for each frame of the plurality of frames. A storage device comprises a computer-readable medium including encrypted digital content stored thereon, wherein the encrypted digital content is encrypted with a frame key that is different for each frame of the encrypted digital content. A content player comprises a computer-readable medium including instructions stored thereon, that when executed cause a processor to decrypt encrypted digital content by reconstructing a plurality of frame keys that are different from each other that are used to decrypt each frame of the encrypted digital content.
