A Digital Watermarking Technology Research Resisting to JPEG2000 Attack
SU Yan-yan · Journal of Suzhou University of Science and Technology · 2009
Based on the characteristic of JPEG2000 compression process, a new digital watermarking method is proposed while maintaining high detection ability to tamper. It accepts JPEG 2000 compression on the watermarked image to a pre-determined quality factor, and rejects malicious attacks. It is a fact that most of the coefficients of high frequency have the same relative energy relations after JPEG2000 compression,and Watson matrix is used to do quantitative modulation parameters. Experiments and theoretic analysis demonstrate a good performance in resisting to JPEG2000 compression and localizing tampered areas. A test of the invisibility, tamper detection capability and robustness of JPEG2000 compression is given.
