Abstrakt přednášky:
Steganography communicates a secret message as an innocuous looking object concealing the fact that something important is being communicated. Steganography is therefore more devious than cryptography, since when someone uses the latter, everyone knows that something is being hidden. Throughout history, steganography has been used by spies, agents, dissidents, and criminals. But with the growing surveillance frequently mandated by governments, its importance will likely grow. The oldest documented uses come from the old Greece at 5 BC. With the advent of digitization, steganography has moved to the new media such as digital images, video, text, file systems, etc.
Design of steganographic algorithms used to be more art than a science. This talk will present method, which to our knowledge the first to principally design steganographic algorithms. Experimental results demonstrated unprecedented security with respect to the state of the art detection methods. More importantly, the method be quickly adapted to the new development of the field.
