Rich models for steganalysis of digital images
We describe a novel general strategy for building steganography detectors for digital
images. The process starts with assembling a rich model of the noise component as a union …

Ensemble classifiers for steganalysis of digital media
Today, the most accurate steganalysis methods for digital media are built as supervised
classifiers on feature vectors extracted from the media. The tool of choice for the machine …

” Break our steganographic system”: the ins and outs of organizing BOSS
This paper summarizes the first international challenge on steganalysis called BOSS (an
acronym for Break Our Steganographic System). We explain the motivations behind the …

Steganalysis of JPEG images using rich models
In this paper, we propose a rich model of DCT coefficients in a JPEG file for the purpose of
detecting steganographic embedding changes. The model is built systematically as a union …

Automatic detection of object-based forgery in advanced video
Passive multimedia forensics has become an active topic in recent years. However, less
attention has been paid to video forensics. Research on video forensics, and especially on …
