Your HEART Size will be your Password! A New Development

Scientists have developed a new computer security system that lets you log in with a heart scan – using the dimensions of the organ as a unique identifier.

The system uses low-level Doppler radar to measure your heart, and then continually monitors your heart to make sure no one else has stepped in to run your computer.
The system, developed by researchers at University at Buffalo (UB) in the US, is a safe and potentially more effective alternative to passwords and other biometric identifiers.
It may eventually be used for smartphones and at airport screening barricades, researchers said.
“We would like to use it for every computer because everyone needs privacy,” said Wenyao Xu, assistant professor at UB.
The signal strength of the system’s radar is much less than Wi-Fi, and therefore does not pose any health threat, Xu said.
“We are living in a Wi-Fi surrounding environment every day, and the new system is as safe as those Wi-Fi devices. The reader is about five milliwatts, less than one percent of the radiation from our smartphones,” he said.
