Weakness in Watermarking and Steganography Tools
Software is now available to alter the extra information stored in files, making it possible to test the robustness of watermarking technologies and to detect and destroy stego'd information. Researchers are making progress in blind steganalysis techniques to detect messeges in carrier files without knowing the underlying technique.
- StegSpy — StegSpy allows identification of a “steganized” file. StegSpy will detect steganography and the program used to hide the message. The lastest version also identifies the location of the hidden content as well. StegSpy currently identifies the following programs: Hiderman, JPHideandSeek, Masker, JPegX, and Invisible Secrets.
