Professor C.C. Chang was born in Taichung, Taiwan on
Nov. 12th, 1954. He obtained his Ph.D. degree in
computer engineering from National Chiao Tung
University. He's first degree is Bachelor of Science in
Applied Mathematics and master degree is Master of
Science in computer and decision sciences. Both were
awarded in National Tsing Hua University. Dr. Chang
served in National Chung Cheng University from 1989 to
2005. His current title is Chair Professor in Department
of Information Engineering and Computer Science, Feng
Chia University, from Feb. 2005.
Prior to joining Feng Chia University, Professor Chang was an associate professor in Chiao Tung University, professor in National Chung Hsing University, chair professor in National Chung Cheng University. He had also been Visiting Researcher and Visiting Scientist to Tokyo University and Kyoto University, Japan. During his service in Chung Cheng, Professor Chang served as Chairman of the Institute of Computer Science and Information Engineering, Dean of College of Engineering, Provost and then Acting President of Chung Cheng University and Director of Advisory Office in Ministry of Education, Taiwan.
Professor Chang's specialties include, but not limited to, data engineering, database systems, computer cryptography and information security. A researcher of acclaimed and distinguished services and contributions to his country and advancing human knowledge in the field of information science, Professor Chang has won many research awards and honorary positions by and in prestigious organizations both nationally and internationally. He is currently a Fellow of IEEE and a Fellow of IEE, UK. And since his early years of career development, he consecutively won Outstanding Youth Award of the R. O. C., Outstanding Talent in Information Sciences of the R. O. C., AceR Dragon Award of the Ten Most Outstanding Talents, Outstanding Scholar Award of the R. O. C., Outstanding Engineering Professor Award of the R. O. C., Chung-Shan Academic Publication Awards, Distinguished Research Awards of National Science Council of the R. O.

On numerous occasions, he was invited to serve as Visiting Professor, Chair Professor, Honorary Professor, Honorary Director, Honorary Chairman, Distinguished Alumnus, Distinguished Researcher, Research Fellow by universities and research institutes. He also published over 850 papers in Information Sciences. In the meantime, he participates actively in international academic organizations and performs advisory work to government agencies and academic organizations.
Title: Extended Exploiting- Modification- Direction Data Hiding with High Embedding Capacity
Abstract: Data hiding is referred as a famous and effective technique for delivering secret message security, in which the secret message is conceled in a cover medium during transmission. At present, reference matrix based sata hiding schemes is limited. In this talk, i'll introduce an extended exploiting-modification-direction(EMD)data hiding scheme to enhance the embedding capacity. An extended EMD reference matrix is established to guide the hiding procedure such that the embedding capacity can achieve as large as 2.5 bpp. Experimental results revearl that the proposed scheme maintains better embedding capacity than some state-of-the-art schemes while keeping great image quality.
