Researchers at the University at Buffalo (UB) have developed a computer security system that uses heart dimensions for identification.

UB professor Wenyao Xu says the system measures the heart via low-level Doppler radar, continually monitoring the organ to ensure no unauthorized party uses someone else's computer.

Xu notes the radar presents no health risks, as its signal strength "is much less than Wi-Fi." He also says the system is unique compared to other heart-based biometrics systems because "no one has done a non-contact remote device to characterize our hearts' geometry traits for identification."

The system not only eliminates the need for user login authentication, but guarantees the computer will not function for someone else, making logging off unnecessary.

"We would like to use it for every computer because everyone needs privacy," Xu says.

The work will be presented next month at the ACM International Conference on Mobile Computing and Communication (MobiCom) in Snowbird, UT.
