With the rapid development of network and multimedia technology,how to protect the multimedia information＇s security has become a hot topic in the international study,digital watermarking technology arises at this historic moment.Today digital watermarking technology has become a hot in the academic circle as the digital works copyright protection is more and more important.In this article,the current mainstream digital watermarking algorithm is briefly described,the DCT domain digital blind watermarking algorithm is proposed.The experimental results demonstrate that the watermarking algorithm satisfys invisibility and has good robustness for the JPEG Ccompression and noise.
