Projects

2GesturePIN

A secure PIN-based authentication mechanism for Smartwatches

ClickPattern

A new secure version of Android Pattern lock resilient to smudge and side channel attacks...

CAPPCHA is a promising alternative to CAPTCHA, which is based on physical nature of human instead of cognitive task. CAPPCHA challenge consist of tilting the smartphone to a specific degree displayed on the screen. The rationale behind CAPPCHA is to use something that the user can do easily while the malware cannot.

Color Wheel PIN

Color Wheel Pin: Usable and resilient ATM authentication.

BrightPass

Using Screen brightness to improve authentication security.
