One or more sensors detect a first user's finger being pressed against a first fingerprint scanner, where the first user's finger has a first user's fingerprint that comprises fingerprint ridges that form fingerprint grooves. A light source on a rotating platform transmits offset light against the first user's finger as the light source rotates on the rotating platform. A camera captures shadow images of shadows in the fingerprint grooves. One or more processors receive and analyze the shadow images in order to determine a shape and depth of the fingerprint grooves. The processor(s) generate a first digital fingerprint file that represents the shape and depth of the fingerprint grooves, and store the first digital fingerprint file for use in future biometric verification of the first user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-dimensional fingerprint scanner","description":"A method and/or computer system generates a three-dimensional image of a fingerprint.
