Apple is investigating ways that future iOS devices could store the biometric details of suspected criminals in cases of theft (via AppleInsider).

An Apple patent published today by the U.S. Patent and Trademark Office describes "Biometric capture for unauthorized user identification", by using an iPhone or iPad's Touch ID feature, camera, and other sensors.

ipadmini4touchid
The proposed system augments typical Touch ID verification by capturing and storing information about a potential thief after six fingerprint unlocking attempts have failed and the wrong passcode is inputted 10 times (after which a "cool down" period or a complete data wipe is activated, depending on user setting).

In another variation, a single failed authentication triggers the capture of fingerprint data and the device takes a picture of the user via the front-facing camera.

In yet other embodiments, the system can be configured by the user to enable or disable various triggers and scenarios in which the biometric capture protocols are activated. The patent also specifies how other data could be logged in the background to supplement the biometric capture, including time stamps, device location, speed, air pressure, audio data, and more.

Flowcharts illustrate different implementations of the security system.

After capture, the data is stored either locally on the device or sent to a remote server for evaluation, while purges of data are activated when the system determines that it is no longer required.

In suggested uses that are likely to be controversial, Apple describes how the server-side aspect of the system could potentially cross-reference the captured biometric and photo information with an online database containing information of known users. Currently, the fact that Touch ID fingerprint data is stored locally and not in a centralized database is considered to be a significant security benefit to users.

There's no reason to believe Apple will implement the forensic technology in an upcoming consumer product, but the patent does highlight Apple's continuing research into how to harden security on mobile devices beyond passcode screens and Touch ID.

Running that print against all the other known Touch ID users would be nice but the security/privacy implications of storing fingerprints on a server would be a huge issue. Perhaps the phone uploads the theif's print and photo to iCloud, which could then be turned over to police by the owner, and run against criminal databases.

some privacy issues here. Just cause u pick up an iPhone and touch the home button does not mean u am a thief, warranting my details to be captured .
No, but if you attempt 10 unsuccessful unlocks of a phone that's in Lost Mode with the owners contact information on the lock screen, I'd say your intentions are pretty clear.

And seems like fodder for the next FBI request too. "You can collect biometric data from thieves so now release fingerprint data on this suspect proving they were operating their phone at time XZY in location ABC."

What a brilliant idea. Wonder how much the technology would cost now to implement because it would be no doubt passed onto the consumer in the phone's price.
What? The technology is already in the phone. This is just a software implementation.

The 'human rights' mob in the UK will go insane over this. Criminals have a right to anonymity, too, apparently.

This has a great potential of reducing theft in the long run.
