The iPhone X's face unlock and the fifth amendment don't mix

Earlier this week, Apple unveiled its new flagship smartphone, the iPhone X. Its marquis feature is a front-facing array of sensors it calls the TrueDepth camera, designed to recognize and track a user's face. It replaces the fingerprint scanner as the biometric method for unlocking the phone. The iPhone X isn't the first device to include this feature. Windows Hello (which is mainly for laptops and tablets), and the Samsung Galaxy S8 also incorporate a facial recognition login, though the latter is based around an iris scanner rather than a whole face match. But Apple has especially made the security of its iPhone a critical aspect of its marketing, refusing in 2016 to unlock the San Bernardino gunman's iPhone.
