Abstract Watermarking, as a new technique mainly used for IPR protection and authentication, has become a research hotspot not long after its appearance. Many effective watermarking algorithms have been proposed. But the mature of watermark technology is not enough for IPR, protection. Confronted with current various attack method, a secure watermarking architecture must be built to standardize the whole process,, from watermark insertion to detection. The AQUARELLE system is a good example for showing how IMPRIMATU--an architecture for
IPR, protection is operated. The secure flaws of IMPRIMATUR and AQUARELLE system wa-
terinarking protocol will also be pointed out. Further, a new secure watermarking architecture will be proposed. Its effectiveness will make up for the flaws mentioned above.
