Abstract
The passive continuous authentication method uses biometric feedback to perform the authentication processes. Computer software and sensors are provided to acquire, memorize, and authenticate both the user's hard (facial) and soft (clothing) biometric information. A registration phase compels the user to register his/her face image into a registration database. Subsequently, the system permits the user to login the system based on facial recognition of the image presented by an attached webcam of the system. During a computing session the system repetitively authenticates the user's identity by comparing the user's acquired face image (hard biometric) to the registered face image in the database. A clothes color histogram (soft biometric) is also computed. The hard biometric recognition mainly decides the authentication result. Otherwise, clothes color histogram matching takes place to decide the result. When the user leaves the terminal the screen locks up. Successful authentication unlocks the screen upon user return.
