Senator Al Franken has raised questions about the privacy and security implications of the fingerprint reader on Apple's new iPhone 5S. "If someone hacks your password, you can change it—as many times as you want. You can't change your fingerprints," Senator Franken wrote. He also pressed Apple for additional details on the protection available to users against law enforcement access to biometric data. In Congressional testimony, EPIC has previously warned that biometric identifiers will "allow for greater data collection and tracking of individuals."
