A novel multimodal behavioral biometric technique is implemented to authenticate/identify users by the way they interact with the input devices namely mouse and keyboard. It is also shown how behavioral biometrics is more efficient and secure than physiological biometric systems and moreover the most secured system is that which uses combination of both. This paper explains how the user will first be enrolled into the system. Sufficient number of samples will ensure the accuracy of the system. During verification, the user data will be first matched with that of the database and a probability module will decide over most probable user to be authenticated. The database matching process and simple probability calculation will ensure a time efficient system.
