摘要:
该文提出了一种用于图像鉴定的脆弱水印方法。该方法利用小波变换提取图像的特征信息 ,采用Hash函数加密生成数字摘要作为脆弱水印 ,给出了整数小波域基于平移窗的多比特水印的非线性嵌入方案 ,并实现了脱离原图的高概率水印检测方法。实验结果表明这是一种行之有效的图像鉴定方法。
Abstract:
T his paper proposes a f ragile watermarking method for image authent icat ion. In the method, the orig inal image’ s feature is ext racted using the w avelet t ransform and encrypted by the Hash funct ion, so the w atermark sequences are generated f rom the message digest. It realizes a nonlinear multiple bits embedding method based on a shif t ing window . This paper develops a secure detection algorithm w ithout original image, the high probability detect ion ability is ensured. Experiment s show the method is very useful for image authent icat ion.
