US military laser 200 meters distance identification capabilities: A laser designed for the US military is able to identify a person to 200 meters using his heart rate.

Could facial, digital or voice recognition technologies have found their heiress? The US military has a new technology - which is presented as a laser - to identify a person within 200 meters through his heart rate, reports the journal of MIT. The cardiac signature of an individual is unique, as are his fingerprints and his iris. This laser, called "Jetson" and designed for the Pentagon, works through classic clothing, but not a combination of ski or astronaut.

At present, the technology takes a little time: 30 seconds. A lapse of time that the US military might not benefit on the ground. Another disadvantage is that the person being analyzed must sit or stand all along the identification. Interviewed by MIT Review, Steward Remaly of the Pentagon's Counter Terrorism Technical Support Office said the technology could be improved: "I'm not going to say it can be done from space, but longer distances should be possible ".

Outside the military, the laser could also be useful in the health sector, since a doctor could remotely monitor the heart rate of his patients.

A laser that could be more effective than facial recognition


The device is based on vibrometry, which detects surface movements caused by heartbeat. The research team then developed algorithms that could extract the cardiac signature based on the laser signals. Ultimately, this technology could be more reliable than facial recognition, which can be deceived by wearing a beard, sunglasses or headbands and requires a front view, difficult to obtain by drone.

This is confirmed by the MIT Review Wenyao Xu, from the State University of New York at Buffalo, which also developed a remote heart sensor that only works on a perimeter of 20 meters: "compared to the data facial biometrics is more stable and can achieve an accuracy of over 98% ".

The US military also uses other biometric recognition techniques such as analyzing the gait of an individual to identify him.
