Analysis of digital watermarking algorithm based on SVD

The first application of singular value decomposition(SVD) to digital watermarking in 2002[1] has attracted scholars' attention ever since. Currently, because of the stability of singular value decomposition and the algebraic characteristics of images, many robust watermarking algorithms based on singular value decomposition have been proposed. This paper introduces the application of SVD to a digital watermarking algorithm. Through four experiments, the paper shows that the SVD-based algorithms evoke problems of uncertainty, as copyright ownership cannot be determined.
