| Abstract | This paper proposes blind fragile watermarking scheme along with the pixel-wise technique. Proposed scheme is capable enough in detecting tampered pixels and also able to provide security. For inserting watermark, 3-LSB substitution technique is used. As scheme is focus on blind watermarking technique that's why, embed self-watermark into the image. Self-watermark is generated by applying some set of operations on the pixel value of host image. For the generation of watermark: Firstly, generate secret matrix from the secret key . Secondly, generate pixel matrix from 5MSBs of pixel. Then, generate image matrix from pixel and secret matrices. Finally, generate final matrix consisting 3 rows and 1 column and this matrix gives 3LSBs which will be embedded into the host image to generate watermarked image. Security is provided by secret key and by using the concept of RSA algorithm. |
