Attacks analysis for keyed blind multiresolution watermarking algorithm
ACOS'07 Proceedings of the 6th Conference on WSEAS International Conference on Applied Computer Science - Volume 6（2014）
摘要
This paper presents noise and compression attacks results for a blind multiresolution watermarking scheme based on a modified Xia's algorithm. The results are based on Levels 2, 5 and 8 of a DWT scheme at different scale factors (α) used in the watermark insertion.
