Biometrics are fast becoming an integral part of online security. From the familiar fingerprint to cutting-edge retina scanning and facial recognition technology, it is increasingly the go-to mechanism for protecting and providing access to sensitive data including money and confidential account information.
Until recently, biometric authentication had been discussed on a largely theoretical basis. Today, significant advances have now made it a truly viable and secure alternative to traditional forms of security, offering the opportunity to improve usability of services for its customers.
Biometric authentication uses an individual’s biological data to verify their identity. This data is nearly impossible to guess and is unique to a single person. Biometric systems can be very difficult to compromise, making them a favoured choice over other single-factor security methods or a welcome addition to multi-factor authentication for high security and enterprise security. But no method is without limitation and there is still a way to go until biometric authentication methods become affordable and trusted enough for widespread adoption.
Read about some of the biometric authentication methods being used today and the strengths and weaknesses they bring to the table on Information Security Buzz.
