A Novel Architecture for Continuous Authentication using Behavioural Biometrics

Abstract

With technological advancements and the increasing use of computers and internet in our day to day lives, the issue of security has become paramount. The rate of cybercrime has increased tremendously in the internet era. Out of the numerous crimes, identity theft is perhaps the one that poses the most dangers to an individual. More and more voices strongly declare that the password is no longer a reliable IT security measure and must be replaced by more efficient systems for protecting the computer contents. Behavioural biometrics is an emerging technology that resolves some of the major flaws of the previous scheme. We first present an overview of behavioural biometrics, followed by a comprehensive literature survey of techniques. Then, we propose a novel system for authentication which uses the concept of a logical DNA integrating multiple factors to build a user profile. This model is known as ‘BehavioAuth’. The new model demonstrates an accuracy of 96% with FAR and FRR being negligible (3% and 3.3% respectively). Finally, we compare the new model with the currently existing mechanisms.
