Ruchira Naskar received a B.Tech degree in Information Technology from West Bengal University of Technology in 2008, and an M.Tech degree in Information Technology from Indian Institute of Technology, Kharagpur in 2010. Since July 2010, she has been a research scholar in the Department of Computer Science and Engineering at Indian Institute of Technology, Kharagpur. Her research interest is in the areas of digital watermarking, multimedia content protection and cryptography. Currently she is working as an Assistant Professor at the National Institute of Technology Rourkela, India.Rajat Subhra Chakraborty has been an Assistant Professor in the Computer Science and Engineering Department of IIT Kharagpur since 2010. He received a Ph.D. in Computer Engineering from Case Western Reserve University (USA) and a B.E. (Hons.) in Electronics and Telecommunication Engineering from Jadavpur University (India) in 2005. His professional experience includes a stint as CAD Software Engineer at National Semiconductor, and a graduate internship at AMD Headquarters at Santa Clara (California). His research interests include Hardware Security including: design methodology for hardware IP/IC protection; Hardware Trojan detection and prevention through design and testing, attacks on hardware implementation of cryptographic algorithms; and reversible watermarking for digital content protection. Dr. Chakraborty has published over 45 articles in internationaljournalsandconferences. He has delivered keynote talks and tutorials at several international conferences and workshops, and has rendered his service as a reviewer and program committee member for multiple international conferences and journals. He is the co-author of three book chapters and two forthcoming books and was one of the recipients of the IBM Faculty Award for 2012. He holds one US patent, and two more international patents and one Indian patent have been filed based on his research work. Dr. Chakraborty is a member ofIEEE and ACM.
