Apple’s new iPhone 5S, which comes with a fingerprint scanner, won’t store actual images of users’ fingerprints on the device, a company spokesman confirmed Wednesday, a decision that could ease concerns from privacy hawks.
Rather, Apple’s new Touch ID system only stores “fingerprint data,” which remains encrypted within the iPhone’s processor, a company representative said Wednesday. The phone then uses the digital signature to unlock itself or make purchases in Apple’s iTunes, iBooks or App stores.
