Over the years, we talked a lot about removing passwords on Spark.
We have looked at software solutions such as biometric options such as OpenID and facial recognition and gait analysis.
We heard about the study of "subconscious code"-
Unusual combination of neuroscience and cryptography.
We even explored the narrative code.
Yes, with the story!
This week, it's all about the vibration power of your bones.
Specifically, the bones in your hand.
Researchers at the University of Rutgers are moving beyond fingerprints and touch screens to develop a touch
Use the unique vibration signal in the bones as a proven sensing technology.
It's called VibWrite.
Chen Yingying is a professor of engineering at Rutgers University and director of the Laboratory of data analysis and information security.
She spoke to Spark host Nora Young about the VibWrite system, which is still in the prototype phase.
How does it work?
Yingying: we need to have a pair of vibration motors and a receiver.
Therefore, they are small sensors of the size of the coin and need to attach two sensors to the surface or below the surface.
When people's fingers touch the solid surface, the vibration signal will capture the behavior and physiological features reflected by people's bone structure, bones, contact surfaces, and the touch and size of the fingers.
In addition, the way you enter PIN and lock modes is also very unique for everyone.
So, even if we have the same password, the way I enter the password will be different from the way you enter the password?
Yes, because our behavior is different and our physiological features are different, which can be extracted by capturing vibration signals.
We are looking for something unique about everyone so that we can distinguish you from me. So cool!
What does it feel when you use it?
In fact, people don't feel the vibration signal, because the signal we use is in the high frequency band, so the human ears can't hear the vibration signal.
So you don't feel anything when you press your finger or slide on a table or door panel.
Can you please draw me a picture of where this authentication system can be used?
Our vision is that it can be used for many intelligent access systems, such as entrance doors for high-rise enterprise buildings or apartment buildings.
Also in the hotel room. -
You put your finger or palm on the door of the hotel and you will have access to your hotel room.
If you have a car, you can put your palm on the door and open your car to get you on the bus.
Improve home safety in smart homes and smart appliances at the entrance.
For example, we don't usually want a small child or an elderly person to operate a hot stove and dryer.
So, in this sense, it can also be used to help in this environment.
