A METHOD AND SYSTEM FOR SECURE WATERMARK EMBEDDING AND EXTRACTION DATA FLOW ARCHITECTURE

摘要

A method for a secured watermark inserting and a detection data flow structure and a system thereof are provided to secure the insertion and detection of watermark in a compressed video domain. A system for a digital media processing comprises a watermark system chip. The watermark system chip comprises a main part CPU(111), an embedded CPU, and a secure processor. The embedded CPU inserts watermark within the video signal. The embedded CPU is controlled the secure processor through the securing bus.
