A Reliable Digital Watermarking Algorithm Based On DCT-SVD Algorithm

Internet image works often use DCT and SVD based image digital watermarking techniques to indicate the attribution right of the work in the process of dissemination.Although this technique has good concealment, the false positive leads to the ambiguity of the attribution right of the work. This paper addresses this problem by proposing a method that uses the principal component of the watermarked image instead of the original singular value, and the experimental results show that the algorithm has strong robustness and security while also solving the problem of false positives leading to blurred attribution rights of works.
