In recent years,following the appear of many digital medium, as a technology of information safety, digital watermarking has been to be concerned by more and more people. At present, it exists many algorithms about digital watermarking of bitmap picture, but the digital watermarking pictures which are generated by these algorithms are easy to be exposed to attack ofcopy thatis the way which enemy copies digital watermarking from a production to another one. The algorithm about defend_false digital watermarking of bitmap picture integrates technology of cryptogram with technology of digital watermarking, and the digital watermarking pictures which are generated by the algorithm can overcome attack of copy.
