Quantum Secure Authentication to prevent credit card frauds

A team of researchers from the Netherlands has proposed a security system for credit cards and passports that would leverage the power of quantum mechanics to create a fraud-proof method for authenticating, dubbed Quantum Secure Authentication (QSA).

The new technology, which is claimed to be impossible to copy, will leverage the fact that photons can be present in several places at once.

QSA will use a strip of nanoparticles fitted in the credit card with a thin dry white paint layer, which will make a photon, when directed towards the strip, to bounce around the nanoparticles until it escape back to the surface, creating the pattern to authenticate the card, revealed a study published in the journal Optica.

The security measure will be able to confirm the identity of any person or object, including debit and credit cards, even if essential information like the complete structure of the card when stolen.

The authentication process, rooted in quantum properties of light, will destroy the information being transmitted by collapsing the quantum nature of the light when hackers attempt to observe the Q and A exchange.

QSA that will function based on an advanced model of "classical multiple-scattering key" system is anticipated to offer a security measure that is resistant to any hacking effort.
