The server verifies the signing target data and the verification information for a predetermined period of time, forms long-term verification information forming information by extracting predetermined information included in the long-term signature data, and transmits the long-term verification information forming information to the verifier terminal. The server receives from the verifier terminal a long-term verification information forming function value calculated using a predetermined function by adding the original data to the transmitted long-term verification information forming information, and verifies the long-term verification information using the received long-term verification information forming function value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Server generating basic signature data using signing target data, electronic signature value and timestamp","description":"A long-term signature verification server receives long-term signature data configured using signing target data, verification information for verifying the signing target data, and long-term verifica","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628281","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.
