Abstract :
In order to avoid forgery problem used in the traditional seal and meet the security requirement of the digital documents, a watermark scheme against counterfeit for signature image is proposed. Watermark embedded in the seal image can improve the seal security, prevent the secret document from the illegal modification and realizes the function of identity authentication and non-repudiation.
