This book discusses blind investigation and recovery of digital evidence
left behind on digital devices, primarily for the purpose of tracing
cybercrime sources and criminals. It presents an overview of the
challenges of digital image forensics, with a specific focus on two of
the most common forensic problems. The first part of the book addresses
image source investigation, which involves mapping an image back to its
camera source to facilitate investigating and tracing the source of a
crime. The second part of the book focuses on image-forgery detection,
primarily focusing on "copy-move forgery" in digital images, and
presenting effective solutions to copy-move forgery detection with an
emphasis on additional related challenges such as blur-invariance,
similar genuine object identification, etc. The book concludes with
future research directions, including counter forensics. With the
necessary mathematical information in every chapter, the book serves as
a useful reference resource for researchers and professionals alike. In
addition, it can also be used as a supplementary text for
upper-undergraduate and graduate-level courses on "Digital Image
Processing", "Information Security", "Machine Learning", "Computer
Vision" and "Multimedia Security and Forensics".
