The user workstation receives credentials information and a second security answer. The user workstation then generates an encryption key. Further, the user workstation uses the encryption key to decrypt the encrypted text and extract the first security answer. Then, the user workstation compares the second security answer with the first security answer and authenticates the second username if the second security answer is the same as the first security answer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure offline authentication","description":"A user workstation stores a vendor identifier and encrypted data comprising a first string of randomized data, a second string of randomized data, and encrypted text, the encrypted text further compri","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9602284","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.
