Special Issue on:
Information Theoretic Issues in Digital Watermarking
Digital watermarking has been proposed as a mean to provide
data authentication and copyright protection of multimedia against
unauthorised uses. According to the watermarking approach, a digital
code, i.e. the watermark, is unperceivably embedded into the data
in such a way that a piece of information, e.g. the identity of
data owner, or the authorised consumers, is indissolubly tied to
the data itself. Later on, such an information can be used to prove
ownership, to trace the dissemination of the data through the network,
or to authenticate it ensuring that no modifications occurred since
creation time. After an initial period characterised by the development
of a plethora of watermarking algorithms, some of them theoretically
sound others based on heuristic reasoning, times are now ripe to
ground digital watermarking on a solid theoretical basis. By modelling
the watermarking process as a communication task, in which the watermark
acts the part of the to-be-transmitted signal, and host data, along
with attacks, that of channel noise, considerable insight can be
got into the performance of watermarking in terms of reliability,
capacity, error probability. It is the goal of this special issue
to present works analysing the watermarking process from an information
theoretic point of view, trying to obtain general results on watermark
reliable recovery, watermark capacity, optimum watermark detection,
channel coding for improved performance and so on.
Topics of interests include (but are not limited to):
- Mathematical modelling of watermark embedding and
detection processes
- Reliable watermark recovery
- Estimation of watermark capacity
- Optimum watermark detection
- Channel coding techniques for digital watermarking
- Bounds on error probability
- Attacks modelling
