steganographySteganography
Steganography refers to the science of invisible communication. Unlike with cryptography, where the goal is to secure communications from an eavesdropper, steganographic techniques strive to hide the very presence of the message itself from an observer. In our research on image steganography and steganalysis techniques, funded by AFOSR, we have contributed in three fundamental areas. The first involves designing novel steganographic and steganalysis techniques, devising a methodology for steganographic security and establishing a benchmark to evaluate the performance of several widely used steganography and steganalysis techniques with regard to embedding rate versus detectability. The second area is concerned with incorporating information-fusion techniques into the steganalysis problem. In practice, since the steganalyst will not be able to know which steganographic technique is being used by the embedder, a methodological approach is absolutely essential in fusing the decisions of a variety of steganalyzers. For this purpose, various fusion strategies are considered and composite steganalyzers for practical scenarios are constructed. The third area is cover-image selection, which is a fundamental and unexploited resource for steganographic embedding. To reduce detectability by state-of-the-art steganalysis techniques, a number of statistical measures are devised and used in selecting the cover image. This approach is further extended to the computation of the steganographic embedding rate of a given cover image.
