| Abstract | ||
| Image watermarking is widely used as a tool for copyright protection and authentication. We propose to embed two visible watermarks in a host image for enhancing protection and strength. If one of watermarks is tampered, the other watermark is used as a support to the first one. We propose three watermarking schemes called visible dual watermarking using wavelet transform; two schemes are working in wavelet domain and the other is a mixture of spatial and wavelet domains. The Proposed watermarking method is robust against attacks like DCT, DWT and JPEG compression schemes, and some geometric manipulation like image resizing. | ||
