Abstract:At this stage,people can get all the information from all over the world without leaving home,and the source of theseinformation is mainly based on the digital resources on the network. To guarantee the copyright and authenticity of these resources hasalways been the focus of research. The digital watermarking technology is undoubtedly the best way to solve this problem. This paperintroduces the four types typical algorithms of digital watermarking and the type of the attack. Finally,it puts forward the index ofevaluating the advantages and disadvantages of the digital watermarking algorithm.

Keywords:digital watermarking;typical algorithm;copyright protection
