With the rapid development of the Internet, more attention has been paid to information security and copyright issues in the network, and people's copyright awareness has gradually been set up. Based on signal processing and image processing, I have studied embedding digital watermark into DCT domain. Through people's copyright awareness has gradually been set up. The maintenance of copyright has become a hot topic, and the development of digital watermarking has solved this problem for people [1]. Thus, watermarks are embedded in color images. Before I add watermark data, I scramble the watermark data. By contrast, the watermark algorithm embedded in the DC component of the RBG model is robust.
