Modern locks that protect our maps from outside interference, are protected only by honest people. Keys to them are divided into two types – physical and digital. But physical key can be faked, and numeric codes to steal.
Each new method of protecting fraudsters invent new methods of hacking, so the rivalry between them and the banks converted to the latter in a very difficult and very expensive technology race.
The essence of the protection offered by the Dutch team is reduced to one of the quantum-mechanical absurdities, according to which the photon is aimed at the target, at the same time falls in the set of its places. Suppose your card covered with a thin layer of transparent material, consisting of a plurality of metal nanospheres. The reader sends an ATM on the strip from multiple photon beam (one can even). These photons hitting every once in a lot of places, start multiple scattering on balls, and when they come to the surface, then draw a picture on it light, which depends only on the internal structure of the layer, that is, on the relative position of the scattering beads, and which can not be played .
In this identification procedure, built on a standard recipe “request-response” cheater essentially not able to intervene.
First, the small number of photons contained in the “request” not enough to get an idea about the “reply”. The authors of the new method compared to the situation with the game at the bowling alley when you throw ten balls, and they immediately fall in two hundred different pins.
Second, even if the fraudster somehow learns how to be answer, he can not play it. Conventional, classical methods, such as fingerprint or retinal pattern, does not protect against intruders and reproduced with surprising ease. So, Ian Krissler, a member of one of the largest hacker networks Chaos Computer Club (CCC), said a few days ago that he was able to copy the fingerprint German Defense Minister Ursula von der Lyayen, using images taken by an ordinary camera.
Do the same thing with fingers Frau Merkel, he could not because she prefers to speak with his hands clasped, but ordinary street poster gave him the opportunity to copy the pattern of her retina.
In order to simulate the response of a quantum picture credit card, he would have to create a coating with absolutely the same molecular structure as the original.
The system proposed by the Dutch scientists, can be implemented in the banking system is relatively simple, using cheap and readily available technologies, where the most expensive unit – laser emitting pulses of coherent light, each consisting of several tens of photons.
The authors of the method claim that it can be used not only in the protection of bank cards, it can be easily used in the maps, omissions, security systems banking and public buildings, and even car keys.
