Adaptive steganographic algorithm on pixel-value differencing
摘要
Abstract
This paper proposed a new adaptive steganographic algorithm based on pixel-value differences between adjacent pixels. The algorithm realized embedding messages by combing the nature of image bit-planes with the human vision quality that eyes were not sensitive to the area where pixels changed frequently and acutely. It chose different embedding strategies according to the differences between the first five bit planes of two adjacent pixels, and modified the last three bit planes of them. Through the theoretical analysis and the experiment results, it proves that the algorithm can obtain high capacity and obtain strong steganography security. Besides,the algorithm has low complexity and can be easily realized.关键词
