Compression Tolerant Watermarking for Image Verification
Digital Watermarking is seen as a viable solution to authentication of multimedia data and hence its security, especially in a networked environment. In this paper we present a new watermarking technique to add a code to digital images in spatial domain. This technique is further shown to be robust under common compression schemes, including lossy compression schemes. Watermark embedding is done keeping in mind the limitations of Human Visual System.We have used a procedurefor error diffusion so as to minimize the chances of image tampering. For the verification of the image, original uncorrupted image is not required. Experimental results show that the watermark is robust to P E G compression. KEYWORDS Watermarking, image authentication, image compression, compression-tolerance.
