Researchers at Rutgers University have developed VibWrite, a low-cost, minimal-power smart access system that can authenticate users by sensing their finger vibrations.

"Everyone's finger bone structure is unique, and their fingers apply different pressures on surfaces, so sensors that detect subtle physiological and behavioral differences can identify and authenticate a person," says Rutgers professor Yingying Chen.

The researchers note VibWrite combines passcode, behavioral, and physiological properties, and it permits users to opt for personal identification numbers, lock patterns, or gestures as methods for gaining secure access. Any solid surface can be used as a verification surface with the device, which includes an inexpensive vibration motor and receiver.

During testing, VibWrite authenticated legitimate users with more than 95% accuracy and a false positive rate of less than 3%.

A paper on the technology was presented Sunday at the ACM Conference on Computer and Communications Security (CCS 2017) in Dallas, TX.
