Digital forensics and multimedia forensics are rapidly growing disciplines whereby electronic information is extracted and interpreted for use in a court of law. These two fields are finding increasing importance in law enforcement and the investigation of cybercrime as the ubiquity of personal computing and the internet becomes ever-more apparent. Digital forensics involves investigating computer systems and digital artefacts in general, while multimedia forensics is a sub-topic of digital forensics focusing on evidence extracted from both normal computer systems and special multimedia devices, such as digital cameras.This book focuses on the interface between digital forensics and multimedia forensics, bringing two closely related fields of forensic expertise together to identify and understand the current state-of-the-art in digital forensic investigation. Both fields are expertly attended to by contributions from researchers and forensic practitioners specializing in diverse topics such as forensic authentication, forensic triage, forensic photogrammetry, biometric forensics, multimedia device identification, and image forgery detection among many others.Key features: Brings digital and multimedia forensics together with contributions from academia, law enforcement, and the digital forensics industry for extensive coverage of all the major aspects of digital forensics of multimedia data and devicesProvides comprehensive and authoritative coverage of digital forensics of multimedia data and devicesOffers not only explanations of techniques but also real-world and simulated case studies to illustrate how digital and multimedia forensics techniques workIncludes a companion website hosting continually updated supplementary materials ranging from extended and updated coverage of standards to best practice guides, test datasets and more case studies

th The 8 International Workshop on Digital Watermarking (IWDW 2009) was hosted by the University of Surrey, Guildford, Surrey, UK, during August 24- 26, 2009.As with previous workshops,IWDW 2009 aimed to providea balanced program covering the latest state-of-the-art theoretical and practical devel- ments in digital watermarking, steganography and steganalysis, and the eme- ing area of image forensics. The selection of the program was a challenging task for the Technical Programme Committee members and reviewers, who ensured the highest quality and reputation of the workshop. From around 50 submissions received from authors in 14 countries, the c- mittee selected 26 regular papers (22 oral and 4 poster presentations). In - dition to the contributed papers, the workshop featured three keynote lectures on watermarking, cryptography and forensics kindly delivered by internati- ally renowned experts, Ingemar Cox, Fred Piper and Ed Delp, respectively. The regular papers and keynote lectures can be found in this proceedings volume. First of all, we would like to thank all the authors, speakers, reviewers and participants for their signi?cant contributions to the success of IWDW 2009.

This book constitutes the thoroughly refereed post-conference proceedings of the 7th International Workshop on Digital Watermarking, IWDW 2008, held in Busan, Korea, in November 2008. The 36 regular papers included in the volume were carefully reviewed and selected from 62 submissions. Areas of interest to the conference are mathematical modeling of embedding and detection; information theoretic, stochastic aspects of data hiding; security issues, including attacks and counter-attacks; combination of data hiding and cryptography; optimum watermark detection and reliable recovery; estimation of watermark capacity; channel coding techniques for watermarking; large-scale experimental tests and benchmarking; new statistical and perceptual models of content; reversible data hiding; data hiding in special media; data hiding and authentication; steganography and steganalysis; data forensics; copyright protection, DRM, and forensic watermarking; and visual cryptography.

This book features selected papers from the 5th International Conference on Mathematics and Computing (ICMC 2019), organized by the School of Computer Engineering, Kalinga Institute of Industrial Technology Bhubaneswar, India, on February 6 – 9, 2019.
