New Classification of Digital Image Watermarking Attacks
数字图像水印攻击方法新分类*

A digital image watermarking attacks was analysed and a new classification which can improve proposed watermar-king attack classifications was proposed.Watermarking benchmark afford an evaluation for watermarking algorithms.Based on the literatures,the recent watermarking benchmark Certimark was introduced and the typical projective translation and rotation attack algorithms in Checkmark and Stirmark were compared.
