System and method for partial encryption of frame-based electronic content

摘要

Various embodiments of a system and method for partial encryption of frame-based electronic content are described. Embodiments may include a partial encryption component configured to receive electronic content that includes multiple frames to be displayed according to a chronological sequence. In various embodiments, such frames may include multiple key frames and multiple reference frames. For each reference frame, content of one or more other frames may be dependent on the content of that reference frame. In various embodiments, for each key frame, content of frames to be displayed subsequent to that key frame may not be dependent on content of any frame preceding the key frame in the chronological sequence. In various embodiments, the partial encryption component may be configured to generate partially encrypted content by encrypting a portion of the electronic content without encrypting other portions of the electronic content (e.g., at least some key frames and reference frames).
