NEW YORK -- Sen. Al Franken is asking Apple for more clarity on privacy and security concerns he has with its use of fingerprint recognition technology in the new iPhone 5S.
The iPhone 5S, which went on sale Friday, includes a fingerprint sensor that lets users tap the phone’s home button to unlock their phone, rather than enter a four-digit passcode.
Franken said that the fingerprint system could be potentially disastrous for users if someone does eventually hack it. While a password can be kept a secret and changed if it’s hacked, he said, fingerprints are permanent and are left on everything a person touches, making them far from a secret.
Apple officials didn’t immediately return an email seeking comment on Franken’s letter.
But the Cupertino, Calif., company has said that this kind of technology significantly boosts security for users.
Apple says it’s not possible to convert a fingerprint from a police file into something the phone will recognize, as the sensor reads a sub-epidermal layer of the finger.
Meanwhile, anyone worried about fingerprint scan has the option of disabling the feature and sticking with the passcode.
