Unlock the phone with lips, ears and heartbeat

Many unique biometric security methods are being developed to meet the increasing needs of users.

Currently, Fingerprint sensor and Face ID type face recognition are two of the most prevalent biometric security methods.

Not only is it safe, biometric security also helps users never forget passwords because passwords are the characteristics of their bodies.

However, fingerprint sensors and face recognition are not the only methods.

Use lips to unlock

Engineers at Hong Kong Baptist University have developed a model that can analyze human lips, including the shape, texture and movement of the lips.

The Florida State University in Tallahassee also pursues similar goals but uses sound waves.

This method achieves outstanding security among voice biometric security methods.

Called VoiceGesture , the Florida State system can turn smartphones into Doppler radar devices, use loudspeakers to transmit high-frequency sound and then record feedback via mic when the user speaks the login password.

Both of these methods achieve an outstanding level of security among voice biometric security methods.

Biometric vibration of the skin

Researchers at the University of Michigan have come up with a solution that enhances the quite unique voice biometric security.

They developed a device that wears a collar, earpiece or glasses, using an accelerometer to measure tiny vibrations on the face, neck and chest area when speaking.

Although the integration of this technology into a user device takes time, it will bring voice biometric security to a new level.

Biometric heart rate

The heart rate biometric system of State University researchers in New York uses Doppler radar to search and receive individual information about the heart rate of each user.

Unlock electronic devices with a heart rate measurement system.

This mechanism will continuously monitor user heart rate to ensure that the user is using the system.

That means that instead of just asking the user to enter the password for the first time, the system will monitor the heartbeat continuously. If the heart rate changes, which means another user is using the system, the protection mechanism will automatically lock.

Security by smell . people

The Polytechnic University of Madrid study is based on the principle that each user has a different smell, and that the identity can achieve an accuracy of over 85%.

However, the error rate of up to 15% is still too high and in some cases it is not acceptable. Apple's Face ID technology currently only has a 1/1 million error rate.

Madrid Polytechnic University said it needed more time to improve the accuracy of the technology.

Biometrics by . butt

Engineers at the Institute of Advanced Industrial Technology in Tokyo devised a unique way to prevent car theft.

This biometric system uses multiple 360 ​​sensors attached to the driver's seat to analyze the shape, size, and power distribution points of the driver's butt. And so, only people with the right identifier of the buttock will start the vehicle.

The car will have a way of unlocking unexpectedly.

New level of fingerprint security

The common problem with fingerprint sensors is that users must be exposed to very small areas on the front or back of a mobile device.

However, the VibWrite biometric system of Rutgers University and the University of Alabama is based on finger vibrations instead of fingerprints.

Since not using a fingerprint sensor device, this system is cheaper and can be deployed on any surface, from opening a car door to opening a desktop computer. High accuracy - over 95%.

 

More than once the idea of ​​using human ears for biometric security is named. Everyone has different ear shapes and this feature can help create a smart security system like fingerprints.

However, it will be uncomfortable for users to unlock smartphones every time to apply to their ears.
