A brain scan can replace passwords once
Text passwords are difficult to remember and easy to break, so many manufacturers work with biometrics - fingerprint sensors on ThinkPad laptops and Apple phones, by eye identification on ZTE smartphones. It is not necessary to remember a fingerprint, and it is more difficult to fake it - although, of course, it is not impossible.
Scientists have proposed a new method : encephalogram.
New technology Brainprint from scientists at Binghamton University suggests the use of a set of electrodes for encephalogram. The system shows 500 images to a person and records the brain's response to them. The technology with one hundred percent accuracy guessed one person out of thirty. Scientists do not offer to start the supply of laptops with encephalogram caps. The Brainprint technology, if it continues to show its effectiveness, can be used at facilities with an increased level of security, including in banks and military bases.

Images are selected for the purpose of receiving certain emotional responses. This is a picture of a piece of pizza, boat, sushi, actress Anne Hathaway, various words. Researchers say that they chose such images to which each person would respond differently. This improves accuracy.
To test the safety of technology, its creators have tried to fool Brainprint. One of the methods included the effect of a flashing lamp in order to “synchronize” the work of the brain of two test subjects. This method did not work - Brainprint did not work.
The main idea of this technology is to recognize a personality by its thinking - no brain activity is visible to anyone. It is important that the user does not have to think about identification, that is, the technology can be used so that the user does not know about it, the developers write.
