For the lack of removing signature information easily in the technology on digital signature,based on semantic watermarking technology,proposed the algorithm based on semantic watermarking.The basic idea of the algorithm was that,on the premise of not making any changes to the semantics of the text,embedded digital signature information through the algorithm of synonymy substitution.In addition,in the stage of data encryption,the comprehensive use of the DES algorithm and RSA algorithm make the cracking and tampering of signature information more difficult.Experiments testify that the algorithm itself is easy to realize,robust and strong anti-testing.
