Abstract :
In this paper we propose a novel pixel-wise fragile watermarking scheme which is able to detect tampered pixels with very high probability. Based on a new technique called Image-Dependent Seed (IDS), the proposed method is not only efficient but also secure against many known attacks. Furthermore, the proposed scheme can be simply implemented with only bit-wise AND and Exclusive-OR operations.
