ToothPic proposes breakthrough software solutions and services based on camera identification, i.e., the ability of detecting which camera shot a certain photo or video. This is possible because every sensor leaves an invisible unique fingerprint on the photos it takes, due to imperfections in the manufacturing process. ToothPic Search is a large-scale image search engine for camera identification in forensic investigations. ToothPic Authenticate enables secure and user-friendly multifactor user authentication by recognizing the smartphone camera. It also allows to generate camera-dependent cryptographic keys to sign with your mobile or for antipiracy solutions.
