The main objective of this project is to figure out the tampered area of the received image and recovering the hidden information in the tampered zones. To detect a image, RS Channel Coding algorithm is used to check bits and for recovery reference bits are used. The proposed scheme significantly outperforms recent techniques in terms of picture essence for both watermarked and recovered image. The watermark image quality is achieved through spending less bit-budget on watermark, while image recovery quality is considerably improved based on the performance of designed sce and channel codes.
