Disclosed is a system configured to process content to enable tracing of at least one of a multitude of subsequent uses of content by at least one user. The system provides for: making markable content from content, iteratively marking the markable content with information such as use information; and later extracting at least one of the iteratively applied marks.

Tracing content usage

The present invention is a system for securing broadcasting content locally at receiving stations that may be remote to a broadcaster. Embodiments of this invention implement controllable and renewable security measures, compatible with many other content processing and display systems. These security measures may include re-encrypting received broadcast content using locally generated keys, watermarking the received broadcast content, and logging both processing and display of broadcast content.
