To illustrate, two devices may generate and exchange a list domain information queries and a list of domain information items, respectively. The lists may be encrypted by respective private keys of the devices. Each device may double-encrypt the respective received list using the respective private key, reorder the double-encrypted list, and transmit the reordered double-encrypted list to the other device. The reordered double-encrypted list of domain information items may be compared to the double-encrypted list of domain information queries to identify indices of domain information queries that match domain information items while maintaining privacy of the domain information queries and domain information items at the devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems, devices, and methods for private query and exchange of domain information","description":"Aspects of the present disclosure provide systems, methods, apparatus, and computer-readable storage media that support private querying and exchanging of domain information, such as Domain Name Syste","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11271894","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.
