An algorithm of applying Bedford's law to detect credit fraud in e-commerce is proposed in the paper and the feasibility is studied. The weakness of the algorithm for detecting financial fraud via Benford correlation coefficients is analyzed and a new detection method for e-commerce fraud defined as credit algorithm based on Bedford's law is established, providing better performance of reliability...
Huffman codes replacement algorithm is a new steganographic method by replacing Huffman codes to hide information. The advantages are simple computation, large capacity, good imperceptibility, and so on. However there is no steganalytic method can be used for the new algorithm. A statistical model of the Huffman codes replacement is presented by steganalysising a MP3 algorithm and a steganalysis scheme...
