Behavioral Biometrics is an established technology that verifies users based on patterns in their behavior. It identifies unique, individual regularities in the ways that people type and move, rather than identifying parts of their bodies (fingerprints or irises), things that they have (key fobs or phones), or things that they know (passwords or biographical details).
I-Check uses behavioral biometrics to analyze typing patterns of users which include the duration of pressing a key (press time) and how long it takes a user to find the next key (flight time). Typing patterns are determined based on analysis of the 44 keys used most of the time. The technology also investigates other metrics of how the individual interacts with the device while typing, using data from device incorporated sensors. I-Check recognizes people by the way they type.
