Biometric Authentication for a Mobile Personal Device

Secure access is prerequisite for a mobile personal device (MPD) in a personal network (PN). An authentication method using biometrics, specifically face, is proposed in this paper. A fast face detection and registration method based on a Viola-Jones detector is implemented, and a face-authentication method based on subspace metrics is developed. Experiments show that the authentication method is effective with an equal error rate (EER) of 1.2%, despite its simplicity
