Abstract

An integer wavelet based multiple logo-watermarking scheme for copyright protection of digital image is presented. A visual meaningful binary logo is used as watermark. The process of watermark embedding is carried out by transforming the host image in the integer wavelet domain. To construct a blind watermarking scheme, wavelet coefficients of HH and LL bands are modified depending on the watermark bits. To add the security, permutation is used to preprocess the watermark. From the experimental results it can be observed that proposed method is robust to a wide variety of attacks. Comparison with the existing methods shows the superiority of the proposed method
