Theoretical Analysis and Detection of Jphide

Jphide is a steganography method based on control-mode table. It is more complex than other methods. Besides, there is no good method to attack it. This paper analyzes the structure of embedding message, selection process and embedding mode. It finds two statistical characteristics. It gives a detecting method, which can estimate the length of secret message as rate is 10%～50%.
