The user interface may be configured to display the decrypted graphic and receive a user input responsive to the decrypted graphic. The server may authenticate the electronic device based, at least in part, on the user input."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure user presence detection and authentication","description":"This disclosure relates generally to a system and method for authenticating an electronic device may comprise a server configured to transmit an encrypted object, the encrypted object having an image ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9614827","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.
