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

摘要

Securing the watermark insertion (embedding), and a method and system for detection of data flow structure and the substrate , by using the embedded CPU may include the step of inserting a watermark in a video signal. The embedded CPU may be controlled by using a security processor via a secure bus. The watermark may be inserted in the compressed video signal that can be switched through a compression / decompression engine. The watermark can be inserted in a decompressed video signal and may be induced to pass through the compression / decompression engine. Requests can be sent to the embedded CPU from a main CPU via the security processor and the secure bus. The watermark may be encrypted using a secure processor. Secure bus may be unable to connect to any device not on the main CPU or chip. The chip can be disabled when the embedded CPU is disabled (disabled). A section of a video signal (section) are can be classified, may be selected for insertion.
