Nowadays, human senses are no longer the only means for secure identification. Specialists have conducted detailed investigation and research in this regard and have now come up with a biometric system that relies on scanning the human heart to determine its size, shape and rhythm, and hence leverage this unique data to authenticate.
The demonstration of this novel invention has been conducted by a team of researchers in the University of Buffalo in the United States. The development of this system, named Cardiac Scan, required three years of extensive work.
This unique tool scans and detects the geometry, shape and size of a person’s heart providing data which unique to each human being. The heart shape does not change, only when a person suffers from serious diseases.
The scanning of the heart is done with a Doppler 2.4 GHz radar. The procedure only takes eight seconds, after which the identification is continuous. This means that as long as the person is using their computer or smartphone, the system recognises them, and locking is automatically done as soon as the person is away or someone else attempts to connect.
This method is highly beneficial as it allows users to benefit from a passive, contactless and transparent tool, thereby alleviating the need for them to physically interact with a biometric player or to remember passwords.
Tested on 78 volunteers, Cardiac Scan obtained a success rate of 98% with people positioned a meter away from the Droppler radar. Currently, the apparatus is able to follow a person positioned up to 30 meters away, which for instance, would allow its usage in airports.
As for the waves emitted by the system, researchers assured that the signal power is inferior to that of the Wi-Fi and represents less than 1% of radiations emitted by a smartphone.
Using the heart as a biometric tool is nothing new. However, as of now, all the work carried out in this regard was related to the signature of the cardiac rhythm, which presents unique traits. Other articles have already investigated cardiac identification, a biometric technology established by a researcher in the Canadian University of Toronto, and which gave rise to the Nymi bracelet.
However, Cardiac Scan is a much simpler solution for users who only need to position themselves in front of the Droppler radar for a few seconds. Nevertheless, researchers still need to succeed in reducing the size of this device to integrate with a mobile or computer terminal.
This will, of no doubt, be the hardest task for them to achieve.
