> About the talk:
>
> Steganography is used to hide the occurrence of communication.
> Recent suggestions in US newspapers indicate that terrorists use
> steganography to communicate in secret with their accomplices. In
> particular, images on the Internet were mentioned as the
> communication medium. While the newspaper articles sounded very
> dire, none substantiated these rumors.
>
> To determine whether there is steganographic content on the
> Internet, this talk presents a detection framework that includes
> tools to retrieve images from the world wide web and
> automatically detect whether they might contain steganographic
> content. To ascertain that hidden messages exist in images, the
> detection framework includes a distributed computing framework
> for launching dictionary attacks hosted on a cluster of loosely
> coupled workstations. We have analyzed two million images
> downloaded from eBay auctions but have not been able to find a
> single hidden message.
