Biometrics is now emerging among the most popular, most effective and often most engaging cyber-defence mechanisms for ably protecting banking customers. By utilising the physical and/or behavioural characteristics that uniquely identify each individual, biometric technology is ideal for security authentication, either as a standalone method or as part of a multi-factor authentication solution. It is that exclusivity that biometrics enables for each customer that is fuelling rapid growth across many key areas of banking security.
