To authenticate the user, activity data describing various activities are collected and stored. The activities may be categorized, for example, as work-related activities, personal-related activities, and social-related activities. The activity data may be utilized to generate challenge questions to present to the user. If the user answers enough of the challenge questions correctly, then the user may be successfully authenticated and granted access to one or more computing resources."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"User authentication based on probabilistic inference of threat source","description":"Aspects of the present disclosure are directed to authenticating a user requesting access to a computing resource.
