Steganography in a Video Conferencing System

We describe a steganographic system which embeds secret messages into a video stream. We examine the signal path which typically includes discrete cosine transformation (DCT) based, lossy compression. Result is the technical realisation of a steganographic algorithm whose security is established by indeterminism within the signal path.
