Title : Graphical Passwords -- Security Analysis and a New Direction of Design

Speaker : Dr. Bin B. Zhu (Microsoft Research Asia)
Date : 8th May (Fri) 10:30AM ~ 12:00PM
Location : #208, Woojung CIC Building.

Abstract:
In this presentation, we’ll first provide a quick overview of our recent work on security, and then describe in detail our recent research on graphical passwords. For graphical passwords, we’ll focus on the most extensively studied click-based graphical passwords. We’ll present the typical click-based graphical password schemes, and analyze their security. We’ll show that all existing click-based graphical password schemes are vulnerable to guessing attacks. Then we’ll present a new direction to design click-based graphical passwords that can thwart guessing attacks.
