Abstract Steganalysis has become a hot topic recently in academia with steganograph widely used in Internet. Based on research results of Least Significant Bit (LSB) steganography in BMP images,this paper describes a run length detecting algorithm and gives the principle and realization of algorithm.The algorithm based blind detection is practical, effective, easily achieved and need not training image database when certain hypothsis conditions are met.
