Popis: | In this paper, a wavelet based scheme for digital image watermarking is presented. This proposed scheme inserts two watermarks in an image which serves two different purposes. The first one is inserted using blind watermarking technique while second one acts as fragile watermark. As it is blind watermarking technique, there is no need of original image at the time of watermark extraction. The insertion of watermark is based on selection of suitable coefficients which are obtained after applying two-level wavelet decomposition. The result produced by this watermarking scheme is good as compared to conventional watermarking techniques. |
