The authentication server authenticates the user of the mobile communication client and the self-aware two-dimensional code. Subsequently, the authentication server transmits designated information expressed by the self-aware two-dimensional code to the mobile communication client, on the condition that the user and the self-aware two-dimensional code are successfully authenticated. Consequently, the mobile communication client is able to acquire the designated information expressed by the self-aware two-dimensional code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication server, authentication system, authentication method, and program","description":"In an authentication system, a mobile communication client transmits to an authentication server a bit signal that includes an image capture bit sequence obtained by capturing an image of a self-aware","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9654291","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.
