Your heart rate can be Password

Various ways attempted to make the security system is impenetrable. More recently, researchers to innovate by creating new security system that uses the rhythm of the heart.
As proclaimed Dailymail, Wednesday (02/15/2012), a person's heart rhythm can be used as their password, and open up the possibility of the presence of an electronic device that can be opened only to take it.
Every person has a unique heartbeat and tidfak nothing beats a really similar to each other. However, researchers from China found a way to mathematically make instant identification on a person's heart rate, and use it as a password. 

"Because of the electrocardiogram signal varies from person to person, and can be used as a new tool for the introduction of biometrics," said the researchers at the National Chung Hsing University in Taichung, Taiwan.
Lead researcher Chun-Liang Lin uses two charts from the palms of the hands of an electrocardiogram, to determine the mathematical properties are unique in their heart rate. In this way, they found that the numbers obtained can be used as a password, and that the system is very safe.
Lin's research system that currently requires a graphics elektrokadiogram of each palm. Then, figure the readings are stored and used to reading the next code.
Lin said, the goal is to build the system to an external hard drive and other devices that can be decrypted and encrypted just by touching it.
