Regarding the security problem of information transmission in mobile terminal,this paper proposes a best matching steganography scheme,Matching steganography scheme Least Histogram Abnormality( M-LHA) based on Least Histogram Abnormality( LHA),and a model of information hiding system based on Android platform. M-LHA steganography preprocesses the secret information by replacement algorithm,and selects the swap that best matches the carrier image for steganography. It is proven that M-LHA algorithm has better relative entropy and more stable histogram distribution in comparison with the traditional LHA steganography algorithm,which can bring the effective improvement in the imperceptibility of steganography system. The information hiding system also meets the safety requirements for mobile terminal users.
