Behavioral and physiological biometrics – a marriage made in heaven

This is a guest post by Zia Hayat, founder and CEO of Callsign. Ever since Apple introduced the Touch ID fingerprint scanner to the iPhone 5S in September 2013, biometrics as a means of identifying consumers has swiftly moved from the realms of science fiction to science fact. Now, using a person's physiological attributes as a means of identification is moving beyond the fingerprint, as Samsung's Note 7 is capable of iris scanning and users of Apple's iPhone X are now able to open their phone with merely a glance. But following recent data breaches and a landmark court case in Illinois, physiological biometrics find themselves on the backfoot, with behavioral biometrics now offering a more robust and secure alternative. Traditional physiological biometrics aim to replace "things that you know" – passwords, PINs, memorable information, etc. – with "things that you are".
