Just like typical fingerprints, everyone has a typical heartbeat and the idea is inspiring the latest US military identification device.
According to the Technology Review report, based on the requirements of special operations forces, the US Department of Defense used this principle to develop an infrared laser device, capable of identifying enemy soldiers. Remote by relying on their characteristic heart rate.
The new Defense Ministry device, Jetson, uses a laser-contact non-contact vibration measurement (laser vibrometer) to detect skin surface movements caused by human heartbeat. This device is an application based on current technologies, which are being used on remote vibration measuring devices for special structures, such as wind turbine blades.
This laser device is able to penetrate clothing and achieve 95% accuracy for identification within a distance of 200 meters back, and it is able to extend the distance further.
Steward Remaly, defense official in the Pentagon's Office of Supporting Counter-Terrorism Operations, told Technology Review: "I am not saying that you can do that in space, but from a longer distance is possible. "
This technology is still in the early stages of development. This laser device cannot penetrate thick layers of clothing and the goal is to sit or stand still, the new identification is effective. The device takes about 30 seconds to read the target's identity. Also need to create a database of heart rate signals.
If the above limits are ignored, the heart rate remote identification will add a new biometric security method, in addition to other methods such as retinal scanning, face detection or fingerprints. Hands, which are playing more and more roles in our daily lives. For example, many smartphones are now using identity security measures through fingerprints and voices.
Even though Jetson is still far from perfect, the identification of the distance through the heartbeat provides some advantages over other traditional identity methods. For example, someone's heartbeat signal will not be corrected like a face or fingerprint.
Representatives of the Anti-Terrorist Technology Department explained that: "Being able to measure the typical heartbeat signals of an individual in a long distance will add the ability to identify the environment when the environmental conditions and changes in face appearance can prevent ability to use face recognition system. "
The office also emphasized that very simple changes to a person's appearance, such as hair, sunglasses or hats, can make remote biometric identification tools useless, but work hiding one's typical heart rate is more difficult.
