Contents
Steganography deals with hiding information into covert channels in order to conceal messages. It is in this way a supplement (not a replacement) to encryption since it aims at preventing information from being seen and not from being understood.
While steganography focusses on the message to be hidden, watermarking has its focus on the covert channel. In fact, watermarking is a branch of information hiding that originated from the need for copyright protection of digital media; it intends to hide information about the medium, the watermark, into the medium in order to prove its ownership.
The course gives an overview of the most popular information hiding techniques/systems in the research community or industry. It presents furthermore attacks on these systems as well as methods to countermeasure these attacks.
