Non-Forensic Odontological Biometrics

While techniques such as biometric face recognition observe facial landmarks and local texture for identification and verification, temporal variability and long term impact of aging reduce recognition accuracy considerably. Facial bone and moreover dental structures, are, however, both exposed directly and much less variable and are routinely used in forensic applications. We propose to use novel optical and ultrasound signal acquisition mechanisms to obtain non-invasive images of dental structures avoiding issues associated with radiographic techniques and review the persistent features of the oral cavity and their suitability to biometric recognition with a view to longterm stability and amenability to detection and liveness testing.
