Everyone has their own unique fingerprint; there is no fingerprint that is the same. In fact many companies use hand and finger scanners for identity proof. Before students sit for the GMAT exam, they must undergo a series of finger scans before being permitted to take the exam.
This same theory will be utilized for the heart. It’s a fact that everyone’s heart rhythm is different, therefore scientists think they can take that uniqueness to protect personal information. A research team led by Ching-Kun Chen, an electrical engineer at National Chung Hsing University, in Taiwan, have developed an algorithm that turns an electrocardiograph (ECG) reading from your palm into an encryption key."He says the goal is to build the system into external hard drives and other devices that can be decrypted and encrypted simply by touching them," reports New Scientist magazine.
An innovative breakthrough like this would allow you to unlock your hard drive by touching your keyboard. Your heartbeat, which would be discharged through your finger, would be your password. How fascinating! By using this technology there would be little chance of hacking and would make banking online, checking e-mail, etc much safer and secure.
