Although steganography -- the practice of hiding a secret message within an innocuous cover medium -- is hardly new, detecting the presence of hidden messages has become considerably more difficult with the advent of high-resolution digital images as carriers. We have been developing statistical techniques to detect (but not necessarily decipher) the presence of hidden messages within a digital image. The basic approach works by finding predictable higher-order statistics of "natural" images within a multi-scale decomposition, and then showing that embedded messages alter these statistics. |
