Abstract :
Digital watermarking used in image forensics has been extensively studied. First, we concluded the research level at home and abroad, including the comparison between the active and passive image forensics, the application of robust and fragile watermarking algorithms in image forensics. Then we proposed three key issues which are unsolved in the application of digital watermark in image forensics. Finally, we suggested the related solutions for the further study of forensic watermarks.
