A team of researchers from the Eindhoven University of Technology and the University of Twente have started to conduct experiments that would enhance the security of credit cards by using quantum physics.
This year’s hacking cases proved that credit card companies cannot ensure the security of their customers alone and researchers are stepping in to aid credit card companies and customers with the help of quantum physics.
A report from the Optical Society says that researchers have used quantum physics to develop a system known as Quantum Secure Authentication. This system will require the verification of a physical password or “key” to confirm that the credit card is unique even if the credit card itself was stolen.
Credit cards using this Quantum Secure Authentication will have strips of nano-particles and laser light will be used on the card to make it valid and ready for use. Researchers believe that by doing so, the credit card cannot be hacked. This method used by researchers is based on the fact that while in a quantum state the laser light reacts in different ways.
Scientists explained in depth how this laser light behaves while in a quantum state and how photons react in a publication of Optica journal.
The nano-particle strip that will be applied on the credit cards is basically a thin layer of paint made from millions of compressed particles. When the laser light is applied over this nano-particle strip will cause the photons to hit the light particles and jump between those light particles forming a pattern. The patters will be unique to every bank and transactions will be validated only if it matches the pattern of that bank.
The lead author of the study, Dr. Pepijn Pinkse, explained that this process is much like dropping several bowling balls that create hundreds of different impacts when they hit the ground.
The equipment that will be able to read these patterns is similar to CD players and contains a chip that can trace images very much like those used in projector designs, it also contains an image sensor.
Scientists believe that this can method could also be applied to the security systems of vehicles or buildings because of the low cost and the fact that is very easy to use.
