This was also an interesting and informative read because it helped me determine better sensitivity settings for various stego algorithms to minimize False-Positives while at the same time reducing False-Negatives.The carrier engine is the core of any steganography tool. It seems to show (compared to the study on False Positives) that a False-Negative is more likely than a False-Positive. One great thing about StegDetect is that it supports the ability to train the program on new, unknown algorithms as long as you have a clean set of images and a steg'ed set of images to 'train it' on.įor a savvy user, this sort of feature can help reduce the rate of False-Positives by improving the detection ability.Īnalysis of False-Negatives w/ StegDetect Nothing is perfect, and this is some research that was done on the reliability of StegDetect. StegDetect is a well known tool for detecting a variety of steganographic algorithms. Steganography For The Computer Forensics ExaminerĪ good primer on steganography in relation to 'the real world'Īnalysis of False-Positives w/ StegDetect Many different methods and programs exist to try and suss out whether an image is steg'ed or not, but here's a couple links to research papers on the reliability of certain tools: there's no guarantee it's THE ONLY needle in there! And worst of all, even if you find a needle. There are new methods of steganography being developed and theorized all the time, so detecting it is quite literally like looking for a needle in a haystack.
