Abstract: Information hiding technology and information hiding analysis technology are widely used in many fields in recent years. Information hiding technology includes steganography and digital watermark. Steganalysis is the attack on steganography, which includes detecting, destroying and cracking. LSB embedding is the very common method to hide message in digital images. Here two statistical methods to detecting the continuous embedding in image LSBs are proposed, which are μ test and X2 test. Some analyses about false negativ negative and false positive are also given in theory. With the experiments, both algorithms can detect the embedding information in LSBs and the approximate size of the message can also be determined.
