PREDAVANJE - Prof. Alex Chichung Kot, IEEE Fellow

Summary: With the advances in digital technology, manufacturing cost of digital cameras, mobile phones and PDAs is dropping and digital broadcasting is becoming mature. The transmission of digital media through internet is getting very popular. Not only multi-level images, video and audio are in digital form, binary images are also digitized in the applications including legal documents, digital books, contracts, electronic drawings and biometrics data.

This lecture provides a review on the latest development in data hiding for authentication in binary images. In particular, security in black and white, an emerging technology for the digital media will be delivered. Different data hiding techniques for binary images using pattern based, contour based, and transform domain based will be discussed and analyzed. Distortion measure scheme is proposed to match with the human visual perception. Data hiding technology combined with secured authentication techniques will be discussed for secured media transmission and tracking. Privacy in biometric data and image forensic will also be discussed in the lecture.

A brief introduction of the research activities in the School of EEE, NTU and the opportunities in getting SINGA Scholarships to pursue PhD degree in NTU will be given at the end of the talk.

Speaker: Prof. Kot has been with the Division of Information Engineering at the School of Electrical and Electronic Engineering (EEE), Nanyang Technological University, Singapore since 1991 as Head of the Division since 1996 for eight years. He is currently Professor and the Associate Chair\Vice-Dean (research) for the School of EEE, overseeing the research activities for the School with 190 faculty members.
