The advances and convergence of computational hardware, multimedia techniques and information
and communication technology (ICT) have brought about unprecedented opportunities for the world
economy. Information can be exchanged in various forms of media through interconnected networks
while multimedia processing techniques facilitate efficient manipulation and fusion of media with
stunning effects, which have already made a profound impact on the ways we communicate, learn and
entertain. However, these advanced technologies could also be exploited for malicious purposes such
as phishing, document forgery, copyright piracy and anti-forensics, to name a few. To prevent abuses of
theses technologies, the research of computational forensics, digital crime and investigation has emerged
in recent years as a new interdisciplinary area, aiming at improving information security, preventing
digital crime, and facilitating digital forensics and investigations.
The past few years have seen an exciting development of interests in the techniques revolving around
the issues of digital crime and forensic investigation. Although a number of quality books have been
published in the literature, the ever-advancing technology in this field entails a constant renewal of
systematic and comprehensive accounts of the latest researches and developments. Aiming at serving
this purpose, this book contains a collection of informative and stimulating chapters written by knowledgeable
experts and covers a wide spectrum of the state-of-the-art techniques for tackling the issues of
digital crime and forensic investigation. Each chapter is a self-contained treatment on one aspect of the
broad subject, allowing the readers to follow any order of their liking. The chapters are selected to suit
readers of different levels with various interests, making this book an invaluable reference for beginners
as well as experts alike.
