Authentication and encryption methods are disclosed that can be used to establish the trust and secure communication between devices that conduct collaborative content screening. Delegation architecture may be based on ascertained screening capabilities of the sink device wherein the source device verifies that the sink device is capable and trusted to perform partial or whole screening operations delegated by the source. Alternatively, delegation architecture may be based on ascertained screening capabilities of the source device wherein the sink device verifies that the source device is capable and trusted to provide correct content credential and content use policy (“content credential”) that is needed for the sink device to determine whether content screening should be performed, and if yes, what content screening operations should be performed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device authentication in collaborative content screening","description":"Content screening operations, which can include watermark extraction and the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11468149","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.
