The steganograhy is the art of transmitting secret messages without raising any suspicion of secret communication taking place. This is usually achieved by hiding the message into innocuous looking objects, e.g. digital images. Steganalysis, is the opposite meaning that we want to detect the presence of hidden messages. Our goal is the development of approaches that works well in practice, which is very difficult due huge variety of images typically used by users. We have developed an unique approach estimating this variety from the observed images. Steganography is a joint project with Oxford University.
