Touch ID

The iPhone 5S' fingerprint sensor is a nice piece of technology, but what is Apple's contingency plan when it gets hacked? One might easily imagine lifting fingerprints from say, a beer mug, and then 3D fabbing a little finger cot that pulses with some of that mysterious "essence of life" that the sensor requires. It is doubtful whether the average user's iPhone would warrant extreme hacking effort, but judging from the eclectic mix of cash, bitcoins, and single-malts already offered on the hacker websites, understanding how this technology works is more than a passing fancy.

Not surprisingly Apple's touch ID can read prints in any orientation, and apparently can be satisfied by toes and even cat paws. Last year, Apple acquired Authentec, which makes a variety of different kinds of scanners, for $356 million. Some details from the Authentec patent hint that the device senses electric flux, and measures the changes when a finger is introduced into an electromagnetic circuit set up by an RF emitter. The sensor itself appears to be an "RF-capacitive" device although the exact physics is not completely detailed.

There are many ways that Apple might go about keeping its devices secure in the face of hacker onslaught. When the pace of technology is significantly faster than the ability to understand and crack it, the innovator need only create the proper level of uncertainty, and the odd, isolated hack would be rendered more-or-less a novelty, rather than a general tool of corruption. For example, there is no rule saying all the fingerprint sensors must use the same exact technology. Furthermore by introducing regular updates which increase the type and level of security, a successful hack might win the occasional bottle of Glenlivet, but not hold up to general use.

Fingerprint verification makes natural biometric measures, like heartbeat or brain waves look downright useless. Ultimately however, we may choose a directly active, and covert means to electronically verify ourselves to our devices. A ring, for example, could emit a simple unlock sequence, as could a small implanted oscillator circuit that chirps out a regular and personalized shibboleth. When wearing a smartwatch, Google Glass, and who knows what else, device verification should be centralized and seamless. Considering the sensor size itself, with real estate and battery life at a premium, the idea of a bulky, single-function sensor hardly cuts it anymore in the new smartphone world.

Many factors could potentially contribute to the life-sensing capabilities of the new iPhone sensor. Moisture, blood oxygenation, flow, might be just a few. If integrated more closely with a camera system, either concentrically or inline, other powerful capabilities — imagine for example, detecting melanoma deep below the skin — may similarly emerge.

For now, the iPhone 5S is more secure than it was with simply a 4-digit passcode, but it's far from unbeatable. In fact, in less than a week after release day people figured out how to beat the Touch ID sensor. Germany's Chaos Computer Club has already demonstrated such a hack using a lifted fingerprint, as seen in the video below. This doesn't mean your iPhone 5S is insecure — if people want your data, and your data specifically, they will often find a way to get it — but now we have conclusive proof that Touch ID can be beat with sub-NSA level technology.
