Biometrics in use
Biometrics falls into the third category of security modalities: (1) what we have: e.g. key, RFID card or ID card; (2) what we know: e.g. password, PIN, challenge/response answers like mother's maiden name or first pet; and (3) what we are: e.g. biometrics, such as our fingerprint, face, iris, etc.
Many people are familiar with biometrics as a security measure at airports or police stations, where they often use a fingerprint as a form of identification, but there are many other uses outside of law enforcement. Biometrics, like any modality, is a not a solution to all problems, but is very effective as one of many layers to provide secure yet convenient authentication to complete a transaction.
Jason Chaikin, president of Vkansee, lays out some of the future uses of biometrics.
Integrating biometrics into our most personal of devices offers convenience and security. The capacitive fingerprint technology in today's devices has been available for more than a decade, and new technologies are in development to enable other biometric authentication, such as iris scanning. These devices use integrated hardware channels like Apple's Enclave and Qualcomm's TrustZone to provide a secure ecosystem to keep biometric data private, making biometrics one of the most secure way to protect a mobile device.
Application of biometrics has proven successful at significantly reducing fraud at ATM and self-serve kiosks. Brazil is an example of widespread application of biometrics reducing fraud at the ATM. Online banking is beginning to use biometric subsystems in mobile devices to access account information and, in some cases, like Chase, even perform cash management without passwords.
Sharing, loss and management of dorm key cards is an ongoing challenge to facility managers. Biometrics, primarily fingerprint access control systems, have been employed to improve operations. USC, for example, has deployed fingerprint access control in each of its 14 dorms to manage entrance to residential dorms. Integrating biometrics into student management systems also provides a platform beyond physical access control, such as ID confirmation for test-taking, cafeteria and book shop purchases, attendance to sporting events and varieties of other services.
