Bias Equalizer for Binary Probabilistic Fingerprinting Codeszed for probabilistic fingerprinting codes utilizing the encoding parameters. Although the proposed bias equalizer is highly dependent on collusion strategies, it can improve the performance of traceability for some typical strategies to which the conventional bias equalizer can not be applied.

Blind Median Filtering Detection Using Statistics in Difference Domainper, we focus on two topics: 1) an analysis of the statistics in the difference domain of median filtered images; 2) a new approach based on the statistical characterization in difference domain to overcome the shortages of the prior related works. Specifically, we derive the cumulative distribution

Textural Features for Steganalysisis. On the other hand, the data hidden in the image texture area has been known difficult to detect for years, and the modern steganographic schemes tend to embed data into complicated texture area where the statistical modeling becomes difficult. Based on these observations, we propose to learn and

JPEG-Compatibility Steganalysis Using Block-Histogram of Recompression Artifactsg the previous art, we work with the difference between the stego image and an estimate of the cover image obtained by recompression with a JPEG quantization table estimated from the stego image. To better distinguish recompression artifacts from embedding changes, the difference image is represente
