Technology continue expending on a daily basis. A team of Indian researchers has developed a first-of-a-kind human authentication through teeth for mobile. The team says that the app acquires biometric samples using the camera on a mobile handset.
Just like face authentication, the app has specific markers that register the teeth of a human for authentication. The name of the study is “Deepteeth: A Teeth-Photo Based Human Authentication System for Mobile and Hand-Held Devices”. It has been authored by Geetika Arora, Rohit K Bharadwaj, and Kamlesh Tiwari from the Birla Institute of Technology and Science (BITS), Pilani.
How the Teeth Lock Authentication works
Explaining the functioning of the app, the team, wrote that the region of interest (RoI) is extracted using markers and the obtained sample is then enhanced using contrast limited adaptive histogram equalization (CLAHE) for better visual clarity.
Furthermore, the team noted to their best knowledge, this is the first work on teeth-photo-based authentication for any mobile device, adding the results have shown “perfect accuracy.” The app, using the front camera of your mobile device, acquires the impression of your teeth first. This is followed by ROI extraction and enhancement. The next function of the app is “deep feature extraction” followed by “enrol/verify and identify.”
The next step is where the authentication really begins. The enrolled extraction then compares the teeth impression with the database, following which the app makes the “decision” on whether or not it matched with the right person.
In conclusion, the authors write that they observed that the less explored teeth-photo has very high recognition and identification accuracy with the special feature proposed in the study.
According to the study, the proposed model works perfectly with a small size sample and is, therefore, power-efficient and suitable for mobile devices.
