Each of the service apparatuses transmits, to the cooperation apparatus, a request to acquire user information of a user specified by an identification (ID) indicated by the ciphertext data and stored in the other service apparatus, together with the ciphertext data. Upon receiving the re encrypted data transmitted by the cooperation apparatus, the service apparatus acquires an ID by decrypting the re encrypted data using a private key, reads out user information, and transmits the user information to the other service apparatus."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cooperation service providing system and server apparatus","description":"Upon receiving ciphertext data transmitted by each service apparatus, a cooperation apparatus according to an embodiment generates re encrypted data by performing re encryption processing for the ciph","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813386","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.
