CSE Speaker Series – Dr. Jun Zheng

On Friday, October 21, in Cramer 221 at 11:00 am, Dr. Jun Zheng from NMT will discuss Dissecting Android Pattern Unlock

Pattern unlock is one of the entry protection mechanisms in Android system for unlocking the screen. By connecting 4 to 9 dots in a 3×3 grid, the user can set up an unlock pattern which is equivalent to a password or a PIN. As an alternative to the traditional password/ PIN, the visual pattern has gained its popularity because of the potential advantages in memorability and convenience of input. In this talk, I will present the security threats facing by pattern unlock and its security weakness. Then I will describe our solution and some related work on how to improve the security of pattern unlock.
