We are a group of researchers and developers at the ISIS Lab of the Polytechnic Institute of New York University.

About a year ago we started a project on improving the security and usability of the iPhone and other touch-based interfaces by applying our expertise in the areas of security, signal processing, pattern recognition, usability, and machine learning. iSignOn is the first of a series of spin-offs of this project.
