Abstract
In view of the characteristics of the electronic seal and the special security requirement, we improved watermarking algorithms based on the discrete cosine transform, which can fight back a variety of attacks. The improved algorithm was used in effectiveness and integrity of electronic seal. Finally, the algorithm analysis was tested in a variety of common attacks. The results showed that the extracted watermark information can keep a higher accuracy rate.
