Abstract: The present invention provides a framework for integration of biometric recognition methodologies of variable computation cost. The system of the present invention comprises a Detection Module (102) which captures images through a camera from a user and detects biometric data through a browser at the client platform; an Image Processing Module (104a and 104b) which enhances the quality of ROI images through relatively fast and relatively slow processing which will enhance the quality of biometric image; a Feature Extraction Module (106a and 106b) which extracts facial features by means of multiple methods which range from relatively computation-inexpensive to relatively computation- expensive from enhanced ROI images; a Feature Matching Module (108a and 108b) which calculated distances between the multiple feature vectors previously extracted and the multiple feature vector which has been stored in database; and an Authentication Module (110) which combines multiple distance scores obtained from Feature Matching process in order to undertakes decision of acceptance or rejection of user based on submission of applicable video-stream. In the present invention, biometric data is captured by means of an apparatus (i.e. camera) attached to the client platform. Upon capturing biometric data by utilizing camera, the processes of biometric detection, signal processing and feature extraction are executed. Concurrent execution of expensive and inexpensive computation would respectively result in relatively slow and relatively fast computation of the biometric feature vectors associated with the user of interest. The present invention allows integration of these relatively fast and slow assessments of biometric authenticity, and also for multiple progressive assessments based on the relative speed of these computations. (The most illustrative drawing is FIG. 1.0.)

Abstract: The system and method of the present invention for biometric authentication is based on challenge response interaction. In particular, the present invention relates to liveness establishment of a biometric authentication system based on challenge and response interaction using an apparatus attached to client platform. The system of the present invention comprising a user (112) which will be verified by utilizing face recognition authentication; a client device (114) comprising of a web browser (116) equipped with a response processor (108) and face detector (110) for capturing and detecting user facial images from visual input (114) and listening to speech obtained from audio input (112) and decode said speech into a response for authentication; an authentication server (116) for issuing challenge test, verifying user?s response and comparing user?s response based on specification of challenge-response interaction provided by user; and a storage (114) for storing at least user secret parameter and face template. The authentication server (116) for issuing challenge test, verifying user?s response and comparing user?s response based on specification of challenge-response interaction provided by user further comprising a challenge issuer (118); a response verifier (110); and a face recognition module (112). The present invention incorporates random challenge and response integrated with facial and speech recognition which provides for user to key in secret pattern and secret number prior to voicing out the result of the operation between random numbers combined with the keyed in secret number. The most illustrative drawing is FIG 2.
