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. Covering recent advances in the field of mathematics, statistics and scientific computing, the book presents innovative work by leading academics, researchers and experts from industry.

th It is our great pleasure to present in this volume the proceedings of the 7 Inter- tional Workshop on Digital Watermarking (IWDW) which was held in Busan, Korea, during November 10-12, 2008. The workshop was hosted by the by Korea Institute of Information Security and Cryptology (KIISC) and sponsored by MarkAny, BK21 CIST (Korea University), ETRI. Since its birth in the early 1990s, digital watermarking has become a mature e- bling technology for solving security problems associated with multimedia distri- tion schemes. Digital watermarks are now used in applications like broadcast mo- toring, movie fingerprinting, digital rights management, and document authentication, to name but a few. Still, many research challenges remain open, among them security and robustness issues, reversibility, and authentication. Continuing the tradition of previous workshops, IWDW 2008 also featured besides papers dealing with digital watermarking contributions from other related fields, such as steganography, ste- nalysis, and digital forensics. The selection of the program was a challenging task. From more than 62 subm- sions (received from authors in 15 different countries) the Program Committee - lected 36 as regular papers. At this point we would like to thank all the authors who submitted their latest research results to IWDW 2008 and all members of the Program Committee who put significant effort into the review process, assuring a balanced program. In addition to the contributed papers, the workshop featured three invited lectures delivered by Y. Q. Shi, C. -C."

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."

The tools of crime constantly evolve, and law enforcement and forensic investigators must understand advanced forensic techniques to ensure that the most complete evidence is brought to trial. Paramount also the need for investigators to ensure that evidence adheres to the boundaries of the legal system, a place where policy often lags behind new innovations. Crime Prevention Technologies and Applications for Advancing Criminal Investigation addresses the use of electronic devices and software for crime prevention, investigation, and the application of a broad spectrum of sciences to answer questions of interest to the legal system. This book fosters a forum for advancing research and development of the theory and practice of digital crime prevention and forensics.

Central to understanding and combating digital crime is the ability to develop new methods for the collection and analysis of electronic evidence. New Technologies for Digital Crime and Forensics: Devices, Applications, and Software provides theories, methods, and studies on digital crime prevention and investigation, which are useful to a broad range of researchers and communities. This field is under constant evolution as the nature of digital crime continues to change and new methods for tracking and preventing digital attacks are developed.
