Biometric security, i.e. fingerprint readers or facial recognition, is a very hot topic recently and it seems that due to its latest technology, the Pentagon definitely leads.
As reported by MIT Technology Review, we are talking about an infrared laser called Jetson, which allows identification of people after beating their heart, and more specifically, movements on the surface of the skin caused by heartbeat. Until now, this type of skills associated us with superheroes like Daredevil rather than actual technologies, but apparently it’s time to change the approach, because the new laser works just like that, even from a distance of 200 meters.
Detecting heartbeats and comparing them with a specific database, the laser can identify a human with 95% efficiency in the optimal conditions tested (because as you can easily guess, it will be much harder for him when there are many people in one place). The undoubted advantage of this biometric solution is the fact that it can not be deceived like face recognition or fingerprint reader, because the rhythm of the heart can not be copied or changed.
According to Wenyao Xu from the State University of New York in Buffalo, who is also responsible for the invention of the heart sensor, but working with a maximum of 6 meters: – Compared to face recognition, cardiac biometrics is more stable and can achieve up to 98% efficiency. Unfortunately, there are also disadvantages, at least for now, because as you can easily guess, this technology will be developed due to its huge potential. Currently, we have to reckon with the fact that the laser works on bare skin or through thin material, such as a T-shirt, but thicker clothes, such as a jacket or jacket, make it useless.
What’s more, the system needs 30 seconds to create a profile and the object must remain motionless at this time. However, as shown in the Combat Terrorism Technical Support Office (CTTSO) dated from 2017, work on Jetson has been going on for a long time and eventually the aforementioned time is to be reduced to less than 5 seconds. What does the Pentagon have to do with it? Of course, it targets military surveillance systems, but the laser can also have practical and commercial applications, e.g. as a smartphone security system or to monitor hospital patients.
