摘要: Techniques for information hiding have become increasingly more sophisticated and widespread. With high-resolution digital images as carriers, detecting hidden messages has considerably difficult. This paper describes an approach to in that uses a wavelet-like decomposition build higher-order statistical models of natural images. Support vector machines are then used discriminate between untouched adulterated
