Active User Authentication on Mobile Devices

Computer Science and Engineering
Lecture / Panel
 
For NYU Community

Speaker: Vishal Patel, Rutgers University

Most mobile devices use passwords, pin numbers, or secret patterns for authenticating users.   However, as long as the device remains active after an initial authentication, there is usually no mechanism by which to verify that the originally-authenticated user is still the one in control of the device.  As a result, unauthorized individuals may be able to use a compromised device to improperly gain access to personal information.  A solution to this problem is active authentication: an authentication scheme that continuously monitors the user's identity even after initial access has been granted. 

In this talk, I will first describe new methods for continuous identity verification based on behavioral and physical aspects of a user's interaction with a device.  I will then highlight some issues and solutions pertaining to the use of continuous authentication in practice.   In particular, I will discuss attribute-based methods we have developed for face-based active authentication. I will also present a general method for quickly detecting intrusions with lower false detection rates in mobile active authentication systems.
