In a preferred approach, the physical object is used to create a digital representation (of the physical object) that, together with some uniqueness associated to the user, gives rise to a key generator seed value. Without knowledge of (a) the physical object itself, (b) how the physical object characteristic is converted (to a digital representation), and (c) the uniqueness value, an attacker cannot reproduce the key generator seed (or the key(s) generated from that seed)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Using everyday objects as cryptographic keys","description":"This disclosure involves the notion of using physical objects to generate public key-based authenticators and, in particular, to use “everyday” physical objects to create a generator seed for a key ge","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9729318","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.
