Passwords have to be ever longer and more complex in order to be secure, which makes them hard to remember.
For the modern day smartphone user, a quick scan of a thumb is faster and just as secure, if not more so – and fingerprints are not forgettable.
As biometrics develops and becomes further embedded to larger purposes (as predicted by Deloitte) they could have a massive benefit for businesses conscious about improving cyber security.
While the fingerprint has been accepted as a means to unlock features alterative biometric technologies, such as voice, facial and iris recognition, are less used. The research showed only 3% of the UK population are making use of these features. This might seem like a surprisingly low statistic, but perhaps this is one which is going to surge over the short-term. After all, the idea of biometrics has seemingly been normalised by the fingerprint scanner.
