Swiss system ups security and reliability of finger-based biometrics

Biometrics will not be the right answer for security, however they are often helpful — so long as they’re strong and effectively thought out. TouchID is all effectively and good, however you wouldn’t safe a nuclear website with it. Properly, motion pictures apart, you in all probability ought to safe a nuclear website with a fingerprint regardless. However this new system from Swiss researchers is a step in the proper path.

Lambert Sonna Momo headed up a collaboration between his firm, International ID, and the École polytechnique fédérale de Lausanne (EPFL), which combines the former’s biometric tech with the latter’s crypto chops.

On the biometric facet is a 3D vein imaging tech Sonna Momo helped put collectively. “These days you possibly can simply and cheaply create faux fingerprints,” he defined in an EPFL news launch. “2D vein recognition know-how is already used all through the world, however the system has its flaws. With 3D evaluation, the chance of counterfeits is actually non-existent.”

Basically, superficially related patterns are simply differentiated once you add one other dimension to the imaging. The scanner itself is comparatively low cost, too — round $300 — and has been examined with all kinds of folks and pores and skin varieties — it’s a serious consideration in biometric optics.

EPFL, for its half, created an equally vital facet of the system: the info dealing with and encryption. In any case, you possibly can’t reset your fingerprint, retina, or veins — as soon as they leak, they’re compromised without end. And essentially privateness is vital with such issues.

So EPFL’s crypto lab put collectively a homomorphic encryption scheme that enables the scanner and ID system to research information with out ever decrypting it. That additionally means information can reside on the device and connectivity may be disrupted with out disturbing security. A fringe profit of the scheme is that if the info is stolen or leaked, patterns constructed into it’ll level on the device from which it got here.

Sonna Momo is hoping the tech will show helpful in hospitals, the place optimistic identification is vital for care, and locations the place fast however correct IDs have to be established, like banks.
