In recent years, multimedia authentication techniques have been widely used in the integrity and content authentication of digital media. Current multimedia authentication schemes can be divided into 2 categories according to the authenticator: digital signature-based and digital watermarking-based. In this paper, a comprehensive overview of current tamper detection and authentication methods based on the digital watermarking is presented. We discuss authentication watermarking system and its desirable features, common methods of attack and their countermeasures, and survey some popular authentication watermarking schemes, finally give some suggestions for future researches.
