The device fingerprint may include pairs of expected values for each of the internal storage cells and a corresponding probability that the storage cell will assume the expected value. Storage cells that have expected values varying over the multiple temperatures may be excluded from the fingerprint. A device is authenticated by a similarity algorithm that uses a match of the expected values from a known fingerprint with power-up values from an unknown device, weighting the comparisons by the probability for each cell to compute a similarity measure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Temperature-profiled device fingerprint generation and authentication from power-up states of static cells","description":"A method, system and computer program product for generating device fingerprints and authenticating devices uses initial states of internal storage cells after each of a number multiple power cycles f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8495431","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.
