Dual Watermarking is used forcopyright protection and authentication. In theproposed system, a Dual Watermarking Schemebased on BPCS and Alpha Channel maskingalgorithm, will be developed to improve therobustness and protection along with security.Our project implemented the BPCS (Bit Plane Complexity Segmentation) technique to embed data into bitmap files. The ultimate goal is to embed as much data as possible into a cover image without detection by human perception or statistical analysis. Our first attempt to implement this hiding technique was on 8-bit grayscale images as our cover object. After accomplishing that version, we manipulated it into a second version that was also capable of using 24-bit color images.First outline the BPCS embedding and extraction technique for grayscale images and explain the subtle differences in the color version. It will also compare and contrast the results of embedding data at different thresholds and capacities for both grayscale and color images.
