Google's developers are working on a project that aims to replace passwords with a frictionless solution involving behavioural biometrics and other authentication tools such as voice and face detection.Known as Project Abacus, the continuous authentication solution works by authenticating user data such as typing speed, but also uses facial and voice recognition.The project is the result of collaboration with 33 Universities, tested with 40tb of data across 28 states.Demonstrated at the Google I/O last Friday, the solution achieved a better false acceptance rate than fingerprint and Pin code authentication in the testing.In a demonstration on stage, Project Abacus was able to clearly tell the difference between two users, which means the security measure could eventually do things like lock down all of the apps in real time when someone who isn't you picks up the phone.
