Digital Image Authentication Based on Convolution Coding
Xinhong Zhang · Jisuanji gongcheng · 2008
A color image authentication algorithm is presented.Message of each pixel is convolution encoded by encoder.After the process of parity checking and block interleaving,redundant bits are offset embedded in the image.Tamper can be detected and restored in pixel-level without accessing original image.Experimental results show the authentication algorithm has good performance in tamper detection,localization and image reconstruction.
