Abstract: Systems and methods for detecting hidden messages and information in digital files are described. In an embodiment, a method of detecting steganography in a compressed digital image includes extracting neighboring joint density features from the image under scrutiny. Steganography in the image may be detected based on differences in a neighboring joint density feature of the image.
