Binary image authentication algorithm based on digital signature
一种基于数字签名的二值图像认证算法

This paper proposed a new binary image authentication algorithm based on digital signature for protecting binary image completely. It used the digital signature to certificate the uniform blocks and used the normalization pretreatment to certificate the non-uniform blocks. False alarms could be eliminated by joint certification. The experiments and the analysis show that the content of binary text images can be protected completely by appending very short digital signature to the original image. With fine v...
