When the determination unit determines that the captured image is unsuitable for the biometric authentication, the determination unit does not perform the biometric authentication by the authentication unit and causes the notification unit to issue the notification."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Biometric authentication device","description":"A biometric authentication device includes a biometric information sensor to read biometric information of a user, a biometric information storage unit to pre-register biometric information of a regis","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11461449","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.
