Attacks and Counteratacks of Digital Watermarking

Digital watermarking systems have gained a large interest in both research and industry in the past few years.Many of new wa-termarking algorithms have been presented,at the same time,many of new watermarking attack algorithms also been presented.These at-tack algorithms will accelerate the development of digital watermarking technique.we systematically review proposed attacks on digital wa-termarking,and we introduce some familiar digital watermarking benchmark.
