The re-authentication can happen without any knowledge and/or action on the part of the user. The re-authentication mechanism can invalidate and/or keep track of the previous security token, such that when a subsequent request is received that includes the previous security token, the new security token can be invalidated, and the user caused to re-authenticate, as receiving more than one request with the previous security token can be indicative that the user's token might have been stolen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic token renewal for device authentication","description":"Approaches are described for automatically generating new security credentials, such as security tokens, which can involve automatically re-authenticating a user (or client device) using a previous se","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9608974","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.
