This paper develops techniques for discriminating between images which used as steganography cover. Algorithm is based on the hypothesis that a particular message embedding scheme leaves statistical evidence or structure that can be exploited for detection with the aid of proper selection of image features analysis. We pointed out the features of image that should be taken more seriously into account in the design of more successful steganography, weight for each of these features determined by using Analytic Hierarchy Process (AHP) which helps to maximize some of the features and gives weight according to the relation between these features. The proposed algorithm tested by using LSB image steganography, stego-image compared with the origin one which gives the promised results.
