As a kind of covert communication technology, stegangoraphy can transmit cryptography using public cover on the internet. However, the behavior is easy to be found because of the cover distortion. To solve this problem, we define two distortion functions to measure the impact of embedding secret. They are called cover perception distortion (CPD) and statistical property distortion (SPD). Then a security stegangoraphy strategy can be generated adaptively by minimizing the two distortion functions. The experiment results demonstrate the effectiveness of our work.
