Abstract

A watermark is a data stream inserted into multimedia content. It contains information relevant to the ownership or authorized use of the content. A watermark which could be recovered without a priori knowledge of the identity of the content could be used by Web search mechanisms to flag unauthorized distribution of the content. Since media will be compressed on these sites, a mark detection algorithm that operated in the compressed domain would be useful. We describe a watermark algorithm which operates in the compressed domain and does not require a reference
