Apple Eyes Way to Leave Fingerprints in the Cloud

Apple’s Patent – Finger Biometric Sensor Data Synchronization in the Cloud

The US Patent and Trademark Office recently has published a patent filing known as `Finger biometric sensor data synchronization via a cloud computing device and related methods’ illustrating a system to record fingerprints on one device through Apple’s Touch ID sensor and thereafter upload them to the cloud to sync them with other devices.

Apple had developed a technology which would sync the Touch ID data with the other mobile devices as well as point of sale system through iCloud. The Touch ID sensor, which was introduced in 2013, is available on the iPhone 5S as well as the latest iPhones and iPads and the sensor needs one’s fingerprint to access the device in order to make purchases using the payment system of Apple Pay.

Setting up a Touch ID can be done by registering one or more fingerprints on your device. Apple, in its patent filing has suggested that the Touch ID enrolment could be complicating for users such as in the case of multiple fingerprints, users or devices could be used. For instance, a couple had to register their fingerprints not only on their own iPhones and iPad, but on each other’s devices as well which seems complicating. Cloud based synchronization could eliminate the requirement of registering all the fingerprints on every device that is in use.

Fingerprint Date Encrypted – to iCloud

With the present technology, the problem is that the fingerprints are stored solely on an iOS device and Apple has explained on the Touch ID page - `iOS and other apps cannot access your fingerprint data, it is not stored on Apple servers, and it is never backed up to iCloud or anywhere else’.

As explained in the filing, one would need to validate their Apple ID account prior to registering their fingerprints, the way one would do on entering their pass code. The fingerprint data is then encrypted and sent to iCloud.

Now to use your fingerprint on an alternate device, one would have to verify them from a `to be matched’ set of fingerprints on the second device and the fingerprints on both devices need to match up with the one stored on iCloud. Going a step further, the second devices in this case could be an NFC enabled point-of-sale system, the one that could be used to buy products through Apple Pay.

NFC/Bluetooth to Sync Fingerprint Data 

The POS would have the fingerprint sensor that one would tap to validate the `to be matched’, set of fingerprints. The technology could utilises NFC or Bluetooth in order to sync the fingerprint data as a secured alternative to iCloud though it would be practical only for syncing two devices being in close proximity of each other.

This type of system would certainly make the process of setting up multiple fingerprints on multiple devices, easy though one of the security benefits of the present Touch ID is that Apple does not seem to store the fingerprints, online. Moreover, Apple would need to prove that the system is secured before the users consider storing their encrypted fingerprints in the cloud. Apple spokesperson had reported that the company does not make any comment on patent filings.
