    Sorted Index Numbers for Privacy Preserving Face Recognition

    This paper presents a novel approach for changeable and privacy preserving face recognition. We first introduce a new method of biometric matching using the sorted index numbers (SINs) of feature vectors. Sinc...

    Gait Recognition Using Wearable Motion Recording Sensors

    This paper presents an alternative approach, where gait is collected by the sensors attached to the person's body. Such wearable sensors record motion (e.g. acceleration) of the body parts during walking. The ...

    Talking-Face Identity Verification, Audiovisual Forgery, and Robustness Issues

    The robustness of a biometric identity verification (IV) system is best evaluated by monitoring its behavior under impostor attacks. Such attacks may include the transformation of one, many, or all of the biom...
