![]() Steganography comes to my mind but despite several effort at cracking it, nothing works. The clue given to me was "anagram" although I could not make much sense of it. Springer, 2001.I've recently been linked by someone to this particular puzzle which seems to point to a hidden file within the image. Moskowitz( ed.)

This process is experimental and the keywords may be updated as the learning algorithm improves. These keywords were added by machine and not by the authors. The paper also outlines some extensions to the proposed embedding method. The method described herein uses a novel, topological approach to embedding. ![]() Furthermore, we claim that our method can also be used as a steganographic method on files stored in JPEG format. This paper describes a steganographic method that encodes the embedded data in the spatial domain, yet cannot be detected by their steganalysis mechanism. However, steganographic embeddings that encode embedded data in the JPEG coefficients are not detectable by their JPEG compatibility steganalysis. In recent work, Fridrich, Goljan and Du introduced a method that is surprisingly accurate at determining if bitmap images that originated as JPEG files have been altered (and even specifying where and how they were altered), even if only a single bit has been changed. ![]() Steganography and steganalysis of digital images is a cat-and-mouse game. ![]()
