New security system uses pulse rate as password


New security system uses pulse rate as password


The researchers have developed a new security system that recognizes the heartbeat if a person and uses it as the password. This offers hope of electronics that the people can simply use to unlock them.

The heartbeats never repeat themselves and that of every individual is unique. The Chinese researchers have found out a way to identify the heartbeat of a person mathematically in just an instant and use this as password.

The electrocardiogram signals will vary between each individual and they can be used as a tool for the biometric recognition, claims the researchers of the National Chung Hsing University in Taiwan.

The research is led by Chun Liang Lin and is conducted by using two ECG readings taken from the palms of the person to find out the distinctive mathematical attributes of the heartbeat.

This number can be used as password and the system will be very secure. Earlier, the biometric security systems were making use of fingerprints and these can be tricked occasionally by photographs.

The new system of Lin taken the ECG reading of the user from both the palms and a key that is based on the reading will be stored and used as password for the later de-cryptions.

Lin insists that the ultimate aim is to build up a system for the external hard drives and similar devices that can be encrypted and decrypted just by touching them.
