The false generated by the false data generator is deterministic and based upon external data inputs, thereby obfuscating whether or not the correct password has been entered."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chip lockout protection scheme for integrated circuit devices and insertion thereof","description":"A system for implementing a chip lockout protection scheme for an IC device includes an on-chip password register that stores a password externally input by a user; an on-chip security block that gene","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8484481","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.
