Information hiding algorithm based on three-pixel block
一种基于三像素点分块的信息隐藏算法*

This paper proposed a new hiding algorithm.It hid information by using the size relation of three pixel values.To hide information,divided the cover image into three-pixel blocks,changed the first and the third pixel value to modify the size relation.In addition,used Arnold transformation to scramble the secret image and used chaotic sequence to randomly embed information.The experimental results show that the algorithm realizes easily and has big hiding capacity,good security and invisibility.When the embe...
