A Novel Approach for JPEG Steganography,nts 1 or -1. The candidates for removing and inserting are searched among all non rounded AC coefficients after quantization. The proposed search technique flags the most appropriate coefficients, which provide less degradation after modification. The proposed data hiding technique based on the modi

A High Capacity Steganographic Algorithm in Color Images,icients at the same frequency in YUV components are selected respectively to compose a triplet as the message carrier, then decide the embedding capacity in each triplet according to the property of the triplet. The modulus 2 or modulus 4 arithmetic operations are applied to the valid triplet to emb

Introduction: What’s Wrong with Literature?atermarking techniques is vulnerable to an intra-video collusion attack because it provides grounds to make statistical inference about information within consecutive frames. An algorithm using bootstrapped time series is proposed to exploit this vulnerability. Experimental results demonstrate that
