摘要： 经典的x2检测算法是目前公认的能唯一检测JPhide的最佳检测算法，但实际上检测准确度并不高。该文基于二次加密提出了一种新颖的JPhide加密检测方法，进行了一系列的实验考证。该方法克服了x2检测算法的缺点，可以较准确地进行JPhide加密检测，降低了误检率。并对该方法进行了进一步的展望。

Abstract: The classical x2 statistical attack is the only best JPhide Stego-detection method that is well-accepted. However, the detection accuracy is not high. This paper proposes a new JPhide Stego-detection method based on second steganography. This method is also proved by a list of experiments. It defends the deficiency of x2 statistical attack and can detect JPhide more accurately with less false detection. There is also a further expection of this method.
