In the meantime, he participates actively in international academic organizations and performs advisory work to government agencies and academic organizations.
Title: Using Meaningful Digital Shadow Images to Recover a Secret Message
Abstract: Secret sharing is an important technique to ensure well protection of transmitted information by dividing a secret message into several shadows that are held among a set of participants. In this talk, I will introduce a novel secret sharing method using two meaningful digital images with cheating detection. It allows a dealer to share a secret message into two different meaningful images through the guidance of the turtle shell magic matrix. Then, after performing a permutation operation, two meaningful shadow images are generated and distributed to two participants. The secret message can be reconstructed only when both participants cooperate by releasing real shadow images. Honest participant in this method can easily detect whether the other participant is cheating via presenting a faked shadow. Experimental results show that this method ensures high quality of shadow images and good embedding capacity. The cheating detection process is also effective and very easy to implement.
Prof. James C.N. Yang,
National Dong Hwa University, Taiwan
CHING-NUNG YANG received the B.S. degree and the M.S. degree, both from Department of Telecommunication Engineering at National Chiao Tung University. He received Ph.D. degree in Electrical Engineering from National Cheng Kung University. He is a professor in the Department of Computer Science and Information Engineering at National Dong Hwa University. Also, Prof. Yang is currently a Fellow of IET (IEE) and an IEEE senior member. He has published several hundreds of journal and conference papers in the areas of information security, multimedia security and coding theory. He is the guest editor of a special issue on "Visual Cryptography Scheme" for Communication of CCISA, and a coauthor of a series of articles on "Image Secret Sharing" for the Encyclopedia of Multimedia. He is the coeditor of two books "Visual Cryptography and Secret Image Sharing" published by CRC Press/Taylor & Francis, and "Steganography and Watermarking" published by Nova Science Publishers, Inc. He serves as a technical reviewer for over 30 major scientific journals in the areas of his expertise, and serves as editorial boards of some journals. Also, has served chairs, keynote speakers, and members of program committees of various international conferences. He is the recipient of the 2000, 2006, 2010, 2012, and 2014 Fine Advising Award in the Thesis of Master/PhD of Science awarded by Institute of Information & Computer Machinery. His current research interests include coding theory, information security, and cryptography.
Title: Covering Codes for Applications in Steganography
Abstract:Steganography is an important research area combining methods and techniques coming from cryptography and image processing. This talk introduces covering code based steganography, which has wide and practical applications in modern digital environment. The covering code, using error correcting code (ECC), based steganography was first proposed by Crandall to improve embedding efficiency and meanwhile reduce the number of modified bits. Many ECC-based steganographic schemes were accordingly proposed, e.g., using Hamming code, BCH code, and Golay code. This talk will briefly describe some steganographic schemes using Hamming+1, Hamming-like, Golay+1, Golay+2, and unequal error protection (UEP). When considering ECC-based steganography on pixel domain, the ECC-based steganographic approach has tight relations between the well-known data hiding technologies LSB and OPAB. This talk we describe these three approaches, which are different ways to change bits for embedding secret data. On the other hand, we also introduce how to apply ECC-based steganography on non-pixel domain, e.g., frequency domain and AMBTC compression domain.
