摘要

The security of digital watermarking methods is based on the assumption that their embedding and detection algorithms are kept secret. They are thus inconvenient for public review and widespread use. A watermarking algorithm that can be open while remaining secure is thus needed. Twelve models that are analogous to cryptanalysis models are described for evaluating the security of digital watermarking. They were used to evaluate the patchwork-based watermarking algorithm and identify its weakness. Two scenarios were then developed that strengthen this algorithm. The use of these models will further the development of an open secure algorithm.
