New smart security system

A new smart security system, Vibwrite, that senses finger vibrations to verify users. The security system could use to gain access to homes, apartment buildings, cars, appliances anything with a solid surface.

“Everyone’s finger bone structure is unique, and their fingers to apply different pressures on the surfaces. So, sensors that detect subtle physiological and behavioral differences can identify and authenticate a person,” said Yingying (Jennifer) Chen, a professor in the Department of Electrical and Computer Engineering at Rutgers University-New Brunswick.

Current smart security access systems mainly depend on traditional techniques that use intercoms, cameras, cards or fingerprints to authenticate users. However, those systems require costly equipment, complex hardware installation and diverse maintenance needs.

According to researchers, the goal of VibWrite is to allow user verification when fingers touch any solid surface. VibWrite integrates passcode, behavioral and physiological characteristics. It builds on a touch-sensing technique by using vibration signals. The new smart security is different than traditional security systems.


“Smart access systems that use fingerprinting and iris-recognition is very secure, but they’re probably more than 10 times as expensive as our VibWrite system, especially when you want to widely deploy them,” said Chen, who works in the School of Engineering and is a member of the Wireless Information Network Laboratory (WINLAB) at Rutgers University-New Brunswick.

The new security system allows user to choose from PINs, lock patterns or gestures to gain secure access. The authentication process can perform on any solid surface beyond touch screens and on any screen size. It is resilient to “side-channel attacks”. It also combats several other types of attacks.

However, the VibWrite system is low-cost and uses minimal power. It includes an inexpensive vibration motor and receiver, and it can turn any solid surface into an authentication surface. Both hardware installation and maintenance are easy, and “VibWrite probably could be commercialized in a couple of years,” Chen said.

In trials, the VibWrite verified legal users with more than 95 percent accuracy and the false positive rate is less than 3 percent.
