Dual Biometrics May Just Be the Authentication Solution We Need
A major problem with biometric authentication is that, when it doesn’t work, there are few good options to proceed with the authentication. Some vendors are trying to deal with this by using a simultaneous, multi-biometric method. For e.g One vendor, Sensory, is making serious headway in figuring out interesting ways to use dual biometrics. Sensory typically recommends allowing authentication from either — voice and facial recognition essentially act as each other’s backup, so if one says no, the other will still allow access. “We’re looking at the way your lips move when you say your passphrase,” Gordon Haupt, senior director of vision technologies at Sensory. That certainly should make spoofing more difficult. And Sensory enables the use of passphrases that change from user to user and are randomly decided by an algorithm. If it’s impossible for a thief to know the passphrase beforehand, that makes spoofing exponentially harder.
