 | Watermarking | | Watermarking research has given rise to very
powerful techniques. Formerly, these techniques were primarily aimed at
multimedia applications where the models and constraints had similar
characteristics. Today a new generation of applications is emerging that
poses exciting possibilities for watermarking techniques. These new
applications most commonly have different goals, requirements and
constraints, which do not necessarily coincide with those of multimedia
applications. As a consequence, the conventional design paradigm has to be
revised. One aspect of this revision involves a shift from static
cover-objects, such as images, audio, and video, to more dynamic ones, such
as data streams. Another aspect requires paralleling the changes in the
governing security considerations. The final aspect concerns the adoption of
a new model of attack channel, which would tend to include fewer malicious
elements, making a watermarking-based approached more viable. With this
point of view, we pose three research proposals that address the preceding
three areas. Our research takes a multiple-pronged approach that applies the
ideas and principles of watermarking to physical-layer communication and
network-security problems. In addition, we are analyzing the security
aspects of many watermarking applications and improving the existing
techniques and protocols with reference to the prevalent security paradigm.
