Biometric Feature-Type Transformation: Making templates compatible for secret protection
Meng-Hui Lim, Andrew Beng Jin Teoh, Jaihie Kim · IEEE Signal Processing Magazine · 2015
Biometrics refers to physiological (i.e., face, fingerprint, hand geometry, etc.) and behavioral (i.e., speech, signature, keystroke, etc.) traits of a human identity. As these traits are unique to individuals, biometrics can be used to identify users reliably in many authentication applications, such as access control and e-commerce. Most biometric authentication systems offer great convenience without requiring the users to possess or remember any secret credentials. For applications that demand greater security, biometrics can be used in complement with passwords and security tokens to offer a multifactor authentication.
