Successfully developed the phone unlocking method ... with the heart

Researchers from the American University of Buffalo have successfully developed a new biometric tool that allows the heart to be unlocked for phones or computers.

Most current biometric security methods encounter an inconvenience, that is, users must actively activate to log in. However, with the new biometric method using heart rate, you can open the passive lock, just by placing your finger on a cushion.

The Cardiac Scan system uses the same shape and size of the heart as a basis for identification.

According to The Register, the researchers created an authentication system called Cardiac Scan that uses the very shape and size of the heart as a basis for identification. The research team at the University of Buffalo in the US hopes that the new technology will soon replace traditional passwords and fingerprints.

New method of measuring heart rate app to determine heart shape and size. The measuring system only takes 8 seconds to determine the shape and heart rate. After that, the system will continuously monitor the heart's condition. This means that if another person sits in front of the device, the system will automatically lock or log out of the account.

The wave output from the scanner is quite low, so it does not affect the user's health.

The maximum distance to monitor heart rate can be up to 30 meters. This is a great condition for Cardiac Scan application at the airport security department

The study's lead author, Wenyao Xu, assistant professor at Buffalo University, said the wave output from the scanner is quite low, so it does not affect user health.

Wenyao Xu also affirmed that, because humans do not have the same heart, the change in size and position will help the scanner to verify each person's identity. Moreover, heart rate involves many biological functions so it is difficult to forge or hide in a living body.

Xu believes technology can be applied on any computer or smartphone to enhance security for users.

The scanner will only work when your heart is beating.

To test the scanner, the team conducted tests on 78 people. The results of user authentication reached 98.61% accuracy, the error rate was only about 4.42%. Testers had to sit quietly in front of the scanner for about 1 meter during the test. Body movement and noise may affect the accuracy of the scanner. Even, the system will not work because the body movement is too strong.

The sensor in Cardiac Scan operates at 2.4GHz to 5kHz, the same frequency as Wi-Fi and Bluetooth. However, the group confirmed that the movement signal from the heart was not interrupted.

This is a rather bold and useful biometric idea. Because the scanner will only work when your heart is beating, and the heart is more difficult to steal than fingerprints.

Cardiac Scan took up to 3 years to develop. The group is expected to introduce the technology at Mobicom - the October International Conference on Computing and Mobile Networks in Utah, USA.
