VLSI Implementation of Reversible Watermarking using RCM
Main Article Content
In this paper the design and implementation of image watermarking algorithm called reversible contrast mapping (RCM) is given. Watermarking is to embed the one important information into the cover media to provide the security to data. Reversible watermarking is one of the important scheme of the watermarking which is useful when reconstruction of original image from watermarked data is necessary after using it like medical and military images. We have used reversible contrast mapping (RCM) algorithm for inserting watermark of size 64×64 in original image of size 128 128. It is integer transform applied on pixel pairs. It gives high embedding rate at lower mathematical complexity and it does not require data compression with lowest complexity.
