The derived-account management apparatus creates derived-account information which becomes valid when the survival condition is satisfied so that the derived-account information includes both the derived-account credence element information which becomes invalid when a validity term of the public key certificate expires and a biometric information template of the user which is valid regardless of this validity term. Accordingly, even if an authentication element as a root (public key certificate) becomes invalid, a derived authentication element (biometric information template) can be prevented from becoming invalid."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Account management system, root-account management apparatus, derived-account management apparatus, and program","description":"A root-account management apparatus generates an electronic signature based on a survival condition and a secret key when an authentication result of a user of a client apparatus is proper, and transm","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8499147","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.
