Detection of Double MPEG Compression Based on First Digit Statistics,PG compression which often occurs in digital video tampering. The doubly MPEG compressed video will demonstrate different intrinsic characteristics from the MPEG video which is compressed only once. Specifically, the probability distribution of the first digits of the non-zero MPEG quantized AC coef

A Time Series Intra-Video Collusion Attack on Frame-by-Frame Video Watermarking,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

Scalability Evaluation of Blind Spread-Spectrum Image Watermarking,G coded bitstreams. We develop two multi-channel watermarking schemes with blind detection, based on additive spread-spectrum watermarking: one employs the DCT domain, the other the DWT domain. We obtain watermark scalability by combining detection results from multiple channels modeled by Generaliz
