Heart beat is your new encryption key!
According to New Scientist every ones heartbeats in a very unique rhythm. It is so unique that there is no chancing of you beating the same beat twice. An electrocardiograph (ECG) would know the difference. They shall probably use your bit to create a secret key.
This is how it works: some of you might remember when you are generating a certificate the computer asks you to move your mouse of do some keyboard activity to generate random number to start creating that unique key to encrypt.
This works based on Chaos theory. Chaos theory is a field of study in mathematics, with applications in several disciplines including physics, engineering, economics, biology, and philosophy. Chaos theory studies the behavior of dynamical systems that are highly sensitive to initial conditions, an effect which is popularly referred to as the butterfly effect. Small differences in initial conditions (such as those due to rounding errors in numerical computation) yield widely diverging outcomes for chaotic systems, rendering long-term prediction impossible in general.
So your heartbeat is used to generate randomness and let Chaos theory generate your supper secrete key for encryption.
Looks like we all have a random heart! Happy Valentine’s Day to all
