Telos Shield is a law enforcement-focused mobile application designed for the NIST mFIT Challenge, utilizing touchless mobile device fingerprinting system and the ONYX software development kit. The app employs a mobile device's GPS and camera to capture identifying data such as face images or documents. The ONYX SDK enables the capture of high-quality digital fingerprint images using existing camera sensors in various field conditions, processing them for accurate comparison against predefined templates, similar to touch-based livescan devices. The solution is optimized for high efficacy in diverse operational environments.
