Your heartbeat could be your password!

Sometimes I thought science is a wonderland not "Alice and the wonderland", Sometimes any thing you see in your dream or you considered that It could only be happen in dream or in movies because something are really beyond imaginations, but scientist are there in the science labs to caught all your dreams and imagination and bring them all in a real world.
Suppose you have a number of accounts on different sites, usually you do what give a same password to all of your accounts because to keep a record of all your password is hectic.Scientist claims that as the thumb print of every person in the world is different likely this ,the heart beat of every person in the world is different from others ,so congratulations to all of you that nobody in world have the unique heartbeat as you have. So they have decided that to use our own heartbeat as our password.A technology in the works might soon allow you to unlock your hard drive by simply touching your keyboard. Your unique heartbeat, emitted through your fingertip, would be your password.Scientist are working to translated a human heartbeat into an encryption key using an electrocardiograph reading from an individual's palm. Their unique series of thump-thumpa generated a secret key.Your heartbeat is so different that that pattern never actually repeats. You will never get the same exact timing of beats twice. So the encryption scheme is based on the math behind chaos theory, which dictates that outcomes are highly sensitive to initial conditions, leading to widely divergent outcomes.
