基于行程编码的二值图像数字隐写算法
Steganography Algorithm on Binary Images Based on Run-Length Encoding
摘要
Abstract
Aimed at the characteristics of binary images,with two colors and the pixels being sensitive to the modification,a steganographic algorithm is proposed for binary images based on run-length encoding.Dividing thecover image into blocks firstly,then the pixels in each block are run-length encoded in zigzag scanning order and the secret bits are embedded by modifying the larger runs.When modifying the runs,the strategy of run splitting and run combining is adopted and the"flippability"of the pixels corresponding to the modified runs is considered. Moreover,utilizing the principle of steganography based on error-correcting code,the shared keys are introduced to further strengthen the security.Experimental results and the analysis show that the proposed algorithm has a considerable embedding capacity,a good visual imperceptibility and a high security.关键词
