An anonymous reader sends this quote from Forbes:
"... it is an almost certainty that within the next few years, three biometric options will become standard features in every new phone: a fingerprint scanner built into the screen, facial recognition powered by high-definition cameras, and voice recognition based off a large collection of your vocal samples. ... We store an enormous amount of our most intimate and personal information on cell phones. Businesses today are already struggling with policies regarding bringing devices from home, and it’s only going to get more difficult.

There are separate questions as to whether these technologies are ready for such a wide-scale deployment."
