Hidden Copyright Mark in Digital Images using Watermarking Technique: A Review

This paper presents a hybrid image watermarking technique for data hiding on high entropy areas of an image. The basic idea of proposed technique is based on embedding of watermark in original image using hybrid DWT SVD watermarking algorithm to produce watermarked image. Then performance of proposed algorithm will be analyzed and compared with existing DWT SVD technique which has been applied to entire image. The proposed algorithm will give best result as embedding watermark on high entropy areas only rather than on entire image. The image watermarking technique on high entropy area is more robust than using entire image. The results will prove that proposed technique improve both capacity and quality of embedded information.
