Research and Development of Digital Image Steganography Detecting System
Yumin Wang · Jisuanji gongcheng · 2005
Of all the stegnography medias, digital image is the most common one. This paper proposes a scheme about digital image steganography detecting system and discusses the key technologies in detail,such as the linearity forecast model of normal image wavelet packet decomposition coefficient, the arithmetic of image character creating based on wavelet packet decomposition and the designment of classifier using fisher linear discriminant. It also introduces the functions and the purposes of the system, moreover, tests and evaluats system performance. At the end , it points out improving direction.
