New biometric technology is effective and inexpensive

Science & Technology October 31, Rutgers University professor of Chinese Chen Yingying led the team developed a new type of biometric technology, called VibWrite, who can detect vibration touch of a finger to verify user.

Since the appearance of Apple's face recognition, various types of biometrics have emerged. We have previously reported using arterial blood flow or heart beat frequency to unlock. But today may be the most cost-effective recognition technology, because the key components of this VibWrite are cheap vibration motors, shock absorbers, and computer chips, and do not even need a touch screen, and its cost is only 1/10 of that of fingerprint recognition. .

Specifically, when the finger presses the unlocker, it absorbs part of the vibration of the vibration motor, and then reflects the remaining vibration back to the unlocker, which changes the trajectory of the vibration transmission. Because each person's skeletal structure is different, each person's vibration is different, VibWrite is to identify the user by judging different types of vibration. In the experiment, the recognition success rate of VibWrite was 95%.

Chen Yingying, the head of this research, is a professor at the Rutgers School of Engineering. His research interests include sensors, Internet of Things, and cyber security. She is also a visiting professor at Princeton University and a member of the editorial board of IEEE. In 2010, she received the Google Research Award, and received the IEEE's Technology Innovation Award in 2017. There are also several international awards.

In fact, Professor Chen proposed the concept of VibWrite in June this year. At that time, he published the paper in the form of a paper on the IEEE and won the best paper award. Not long ago, Professor Chen showed VibWrite's finished products at the computer security conference in Texas. The VibWrite at the conference was installed under a wooden panel with 9 digital vibration points. The user can press these number keys or draw graphics to unlock.

At present, VibWrite is still a prototype stage, and researchers will conduct more tests in the next step, for example, under different temperature and humidity environments. If you complete a variety of tests, can be used for home unlocking, unlocking the doors, and even safe areas, if Apple has this technology, you can cut off the bangs it?
