Speech Title: Personal Authentication Systems with Graphics
Abstract: Currently, the most commonly used personal authentication method is a text-based password system. In this talk, several graphical password systems that can replace text-based password systems will be introduced, and a new personal authentication system using a graphical password system will be introduced. The existing text-based authentication solutions bring in the trade-off issue between security and usability. The main reason is short passwords are easy to remember but not secure enough as they are vulnerable to password guessing or shoulder surfing attacks. In contract, long passwords can ensure security, but they raise usability issues due to the difficulty of memorising, recalling, and inputting passwords. In this talk, number of image-based authentication solutions will be proposed. The next-generation personal authentication system to be introduced in this talk has strong security and high usability.
Biography: Gi-Chul Yang received his M.S. degree from Department of Computer Science, the University of Iowa, USA in 1986 and Ph.D. degree in Computer Science and Telecommunications Program from the University of Missouri, USA in 1993. Currently, he is a Professor at Mokpo National University, where he has been working since September 1993. He was also a Director of Information & Computing Institute, School of Information Engineering and University Library at Mokpo National University.
His research interests include Artificial Intelligence (AI) and Human-Computer Interaction (HCI). He published the research articles more than 200 and got several patents. He was working on personal authentication schemes and published papers in various Journals including ‘TIM: Secure and Usable Authentication for Smartphones’ to be published in Journal of Information Security and Applications. He is, currently, pursuing to develop more secure and user-friendly authentication system using EEG data and AI technique. He was a Visiting Scholar at Heriot-Watt University, University of Hamburg, University Institute of Lisbon and University of Porto in 2002, 2015 and 2022 respectively. He collaborated with professors at Linkoping University, University of Zurich, University of Missouri, University of Auckland, Drexel University, Queen Mary University in London, Surrey University and University of Hawaii. He is an author of several books (written in Korean) and was an editor of Springer’s Transactions of Engineering Technologies. He gave keynote speeches and served as a committee member of various international conferences including a conference chair and co-chair. He is, also, an editorial board member of International Journals such as American Journal of Computer Science and Technology (AJCST) and Journal of Image and Graphics (JOIG).
