A Review on Detection of LSB Matching Steganography

Jiaohua Qin, Xuyu Xiang and Meng Xian Wang
LSB matching steganalysis techniques detect the existence of secret messages embedded by LSB matching steganorgaphy in digital media. This study presents a survey of LSB matching steganalysis methods for digital images. Firstly, study described the structure of LSB matching steganalysis, which includes three parts: LSB matching steganography, detectors for LSB matching and the evaluation methodology. Secondly, study classified the existing detection algorithms into two categories according to the fact that the main contribution of the algorithm is detector or estimator. For the detectors, study classified the existing various methods to two categories, described briefly their principles and introduced their detailed algorithms. For the estimators, study introduced the existing two estimating methods for LSB matching. Finally, study concluded and discussed some important problems in this field and indicated some interesting directions that may be worth researching in the future.
