Abstract

One Anti-scanning & printing digital watermark algorithm is studied which can be used in electronic seal Anti-counterfeiting system. Spread spectrum coding strategy is used for embedding the watermark of bigger capacity. The experimental results show that the algorithm can withstand pixel distortion and geometry distortion at the same time which can be used in digital watermark of the electronic seal anti-counterfeiting system and paper certificate and raised the security of watermark detection system in very great degree.
