The method comprises acquiring an image of a finger of a user; identifying a set of minutia points in the image; generating a code by a transformation of the minutia points, the transformation including: (i) creating a matrix from features of the minutia points; (ii) obtaining characteristic invariants of the matrix; and (iii) the code being formed based on the characteristic invariants of the matrix; and outputting the code in association with the user or the finger. The characteristic invariants may be the eigenvalues of the matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for fingerprint encoding, identification and authentication","description":"Computer-readable media tangibly embodying computer-readable instructions stored in a memory and executable by a processor of a computer, wherein execution of the computer-readable instructions cause ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9690972","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
