A day after Apple unveiled its new iPhone X — a device that its owner can unlock using facial recognition — Sen. Al Franken is pressing the tech giant to detail the privacy and security safeguards it has in place for biometric data.

To Franken, the concern is that Apple could use the so-called faceprints it collects through its new unlocking system, called Face ID, "to benefit other sectors of its business, sell it to third parties for surveillance purposes, or receive law enforcement requests to access it facial recognition system — eventual uses that may not be contemplated by Apple customers," the lawmaker said in a letter to the company Wednesday.
