With the rapid development of Internet technology, the importance of the information security issues can’t be ignored more and more.In recent years, as the new communications technology, information steganography has gradually been widely studied and applied because of its unique concealment.Currently, steganography techniques based on digital image have been extensively studied, and steganography detection techniques have been widely developed. However, most of steganography detection technology is based on specific detectionthat is to say, only one or a class of steganographic algorithm is used for detection.In the meanwhile, with the limitation of different image format of steganographic carrier,specific steganography detection technology cannot meet a variety of steganography detection, analytical scientific research and applied practice.In this paper, current digital image steganography detection techniques are deeply studied, and the existing problems of actual application requirements and current steganography detection software are analyzed. A novel digital image steganography detection system is designed in this paper. In this detection system, steganography detection using BMP or JPEG images is supported. Simultaneously, thenine current main stream steganography algorithms are available to be detected, which is able to overcome the problems of single image format carrier supporting and lack of detect steganographic algorithms in existing steganography detection software. BMP, JPEG as the carrier.Through a variety of experiments, this system can detect nine steganography algorithm, including LSB replacement, LSB matching MLSB, JSteg, F5, OutGuess, MB1, MB2, JPhide. With the increasingof the embedding rate, the detection result will bebetter, It has practical application values and practical significant.
