1) Ultrasonographic identification
声像图鉴别
2) image authentication
图像鉴别
1.
This paper proposes a fragile watermarking method for image authentication,in the method,the original image is firstly divided into 8×8 blocks,then choose the region to be protected.
该方法首先对图像进行8×8分块,计算每一块的DCT值,然后选择所要保护的区域,确定完全属于该区域的分块,并提取这些分块的特定位置的低频分量,采用Hash函数加密生成相应的具有固定长度的数字摘要,然后选取该数字摘要的若干位作为脆弱水印,并把其隐藏到该区域其余的DCT分块中去,以实现水印检测时不需要任何额外信息,试验表明这是一种行之有效的图像鉴别方法。
