A fast CAM-based Watermarking extraction on FPGA

摘要

A CAM-based (Content Addressable Memory) system for fast Watermarking extraction has been proposed and implemented on hardware system using FPGA device. The system has a simple structure, does not employ any Central Processor Units (CPUs) or complicated algorithms for extracting hidden information. The authors take advantages of CAM which has an ability of parallel multi-match mode for designing the system. This increases the decryption performance of the Watermarking extraction system. The fast proposed system is applied to fast Watermarking extraction on 2-dimension (2-D) data.
