ToothPic is a university spin-off of Politecnico di Torino, founded by researchers with years of experience in the fields of signal processing, camera sensor fingerprinting and multimedia forensics.

ToothPic develops patented technologies for camera identification, which allow to go back to which device took a certain photograph thanks to the imperfections of the photographic sensors. Based on these technologies, ToothPic has developed the most secure multi-factor authentication (MFA) system to date, in which the user is identified by demonstrating ownership of his smartphone.
