Abstract

Digital watermarking technology is an important means of copyright protection. This article decomposes RGB for the color image and embeds the algorithm of multiple watermarks in the grayscale image of R, G. The algorithm increases the amount of watermark embedded and solves the interference problem of embedding multiple watermarks. The experiment proves that the algorithm of embedding watermark in the frequency domain has better robustness to resist Shearing attack, Gaussian noise attack and JPEG compression attack.
