Eight to eighty, now more or less everyone is speaking louder on the smartphone. Presently practically all telephones have face open or biometric frameworks.  But now the days of unlocking the phone by showing face or with fingers are over. The phone will open when you show your teeth! You must be thinking that what is the matter.

This time Indian scientists have made a technique to unlock the phone by showing teeth. Finger impression open is very well known on cell phones.  However, over the years, the popularity of Face Unlock has surpassed all other authentication methods.

The technology can be used on mobiles and other handheld devices. Scientists say that a special map has already been made for it. The app will collect biometric information using the mobile camera. Other applications open the telephone by taking a gander at the face, but this app has the advantage of unlocking the phone using human teeth.
The study of unlocking the phone with the help of teeth is called diphtheria. The study was published by Geetika Arora, Rohitke Bhardwaj, and Kamlesh Tiwari of Birla Institute of Technology and Science (BITS), Pilani. It has been said that mobiles and other handheld devices can be used for authentication by taking pictures of human teeth.

Elaborating on the effectiveness of the app, the scientists said that regions of interest (ROIs) are isolated using markers. From there it is amplified using Contrast Limited Adaptive Histogram Equalization. As a result, the clarity of the photo is better.

Scientists have further claimed that this method can be used to unlock the phone in a more accurate way. How the authentication of the phone will work through the image of the teeth, has been explained through a diagram in the research paper. First, the app will take pictures of your teeth using the front camera of the mobile phone. It was followed by Region of Interest Extraction and Enhancement. And then the app will enroll/verify and identify by extracting the deep feature.

The next step is to start the authentication task. This time the app will match the named extraction with the database. Then the app will decide whether the image matches the database or not.

Scientists also say that even if you have never used a toothpick to identify a person before, it is possible to use a toothpick to successfully identify a person.

Although the first training takes some time, after the training is complete, this technique will be able to work very efficiently.
