Impenetrable ATMs Thanks to Einstein | Digital Trends Spanish

ATMs are a fast and convenient way to obtain cash, however it is not always the safest.

As technology advances, we see more and more sophisticated ways used by thieves to hack into these devices and thus access the passwords entered by users.

For this reason, a group of researchers from Canada and Switzerland proposed a system that would make it possible to manufacture super-secure ATMs.

For this, the scientists have been based on the Albert Einstein theory of relativity, their intention is to replace the PIN with a kind of mental game that allows the ATM to verify that, indeed, the user is the owner of the account at the one that accesses.

For this, scientists have relied on the test of tricolor, which is a difficult-to-solve mathematical problem that theorists have studied for many years.

This problem begs the question: How can you color a huge shape map with three tones so that the same colors never touch?

Scientists propose to bring this concept to ATMs and suggest giving all users a device containing a unique colored map with a pre-programmed tri-color solution.

How would it work?

To withdraw money, the device would be connected to an external outlet of the ATM, which in this case would be the verifier.

The machine would consult the user’s device and despite the complexity of the tricolor, the device could respond immediately because it has been programmed for that.

Finally, the cashier would verify the identity and deliver the money thanks to the correct responses from the user’s device.

Scientists even propose the use of two devices to make the level of security based on the three-color maps even higher.

“The underlying idea is precisely the same as that of a police officer investigating and asking two separate questions of two suspects in different rooms, so that they cannot communicate,” the investigators explain.

“If they tell the same version of the story, it is a good indication that they are telling the truth.”

According to experts, the reason the devices could not communicate is based on Einstein’s theory of special relativity, which in other respects limits the speed at which information travels.

“With special relativity it seems quite reasonable to believe in this non-computational but physical assumption that information cannot go faster than the speed of light,” the authors add.
