Abstract
The digital information revolution has brought about profound changes in our society
and our lives. The many advantages of digital information have also generated new
challenges and new opportunities for innovation. This thesis discusses the issues
regarding multimedia data hiding and its application to multimedia security and
communication, addressing both theoretical and practical aspects, and tackling both
design and attack problems.
In the fundamental part, we identify a few key elements of data hiding through
a layered structure. Data hiding is modeled as a communication problem where
the embedded data is the signal to be transmitted. Various embedding mechanisms
target different robustness-capacity tradeoffs. We study this tradeoff for two major
categories of embedding mechanisms. In addition, we have found that the un-
evenly distributed embedding capacity brings difficulty in data hiding. We propose
a comprehensive solution to this problem, addressing the considerations for choosing
constant or variable embedding rate and enhancing the performance for each case.
In the design part, we present new data hiding algorithms for binary images,
grayscale and color images, and videos, covering such applications as annotation,
tamper detection, copy/access control, fingerprinting, and ownership protection. The
designs provide concrete examples regarding the choice of embedding mechanisms,
the selection of modulation/multiplexing technique(s) for hiding multiple bits, and
the handling of uneven embedding capacity. Data hiding can also be used in video
communication to convey side information for additional functionalities or better
performance. This is demonstrated by the novel approaches for real-time transcoding
and error concealment.

Because many data hiding applications are in a competitive environment where
an adversary has an incentive to obliterate the embedded data, testing the systems’
robustness and security via attacks is important. In the attack part, we discuss a
number of attacks and countermeasures for data hiding systems. Our investigation
begins with three specific types of watermarking schemes, in which full knowledge of
the watermarking algorithms is available. We then study the attack problems for
digital music under a unique competitive environment, in which the watermarking
algorithms are unknown to analysts.
