Quantum physics may be key to more secure credit cards

first_imgby: Dianne DepraThe onslaught of hacking cases just this year has highlighted the frail security that credit card companies are providing consumers. However, researchers from the University of Twente and the Eindhoven University of Technology may have found the solution, improving credit card security with the help of quantum physics.In a study published in the journal Optica, the researchers developed an authentication method that is impossible to copy, acting as a more secure version of a “Q&A” system. The method works by taking advantage of the quantum-physical fact that it is possible for photons (light particles) to be in several places at once.For the method to work, a credit card or any card that requires security, such as an identification card or building pass, is fitted with a dry white paint layer. Although paper-thin, the layer of paint contains nanoparticles in the millions. If a photon is directed at the paint, it will bounce around the nanoparticles until it finds a way out.A bank, for instance, sends out a unique light pattern for every transaction. Think of this as the “question.” The “answer” will be the resulting light pattern formed as the photon looks for a path to escape. A transaction will only be approved by the bank if the resulting pattern achieved is correct. continue reading » 1SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblrlast_img read more
