The WebStego system was developed with the intention to give researchers working in the field of image steganography and steganalysis access to practical implementation of selected algorithms developed by the members of the DDE laboratory. In its current form, WebStego contains steganalytic techniques for digital images in the BMP, GIF, and JPEG formats. The users can upload their images to this site and run steganalytic techniques on them. The output of the detection algorithms can be saved as a text file. This service is for educational and research purposes only. The development of WebStego has been funded by the Air Force Research Laboratory in Rome, NY via the research grant F30602-02-2-0093 New Generation Methods for Digital Security: Steganography, Steganalysis, and Authentication Watermarks.
