The heart could be used as a password to unlock devices

The researchers managed to develop a biometric system capable of scanning people’s hearts to lock or unlock devices, using the size of the vital organ. The study is due to the University of Buffalo. These experts say their research represents the next step in the IT security industry, as no two people with equal hearts have been identified so far. Through the use of low-level Doppler radar, which continuously identifies and monitors the heart, it is possible to ensure that a blocked computer is not being used by another person.

The research team plans to present this technology at the International Mobile Computing and Communication (MobiCom) Conference, which will be held next month. Led by Wenyao Xu, of the Department of Computer Science and Engineering at the University of Buffalo, the researchers are trying to use this system on computers, condensing it to a dimension that can be inserted into the keyboards themselves and, possibly, also install it on smartphones.

The waves emitted by the radar system are weaker than Wi-Fi waves, so they pose no threat to our health, according to Xu. Who explained that the system reader is 5 milliwatts, that is less than 1% of the radiation emitted by our smartphones.

This scanner takes at least eight seconds to perform the initial heart scan and thus continuously recognizes the registered organ. IS based on the geometry of the heart, including shape, size and heart rate. Since hearts don’t vary in shape, it seems like a good way to protect a sensitive device.

Mechanical tension makes the heart stronger

In addition to being a secure system because it is not possible to duplicate a heart, the researchers reveal that the system is much better than other biometric systems, as it is a non-invasive and remote access without contact. The device can measure and monitor a heart from a distance of up to 30 meters.
