Abstract: With the development of internet and digital of the multimedia information, and aiming at protecting the digital image, digital watermarking used for image authentication has been a hot research focus. The image authentications research status and analysis of aggressive behavior were proposed. Some typical image authentication algorithm was introduced. Finally, the future development of digital watermarking for image authentication was also analyzed and conjectured.
Key words: image authentication; semifragile watermarking; tamper detection
