Application: Information provision system, information provision method, and non-transitory computer-readable medium (Patent ID: US20240048391A1)

The patent filed by NEC Corp. describes an information provision system that utilizes a distributed ledger and blockchain technology to securely provide information. The system involves an information accumulation server and an information provision server, with the former acquiring and accumulating information containing public and private data, while the latter transforms private information into hash values, registers it on a distributed ledger, and responds to information provision requests by comparing hash values and transmitting information accordingly. The system ensures data integrity and authenticity by verifying hash values and detecting falsified private or public information.

Furthermore, the patent outlines a method for information provision using the described system, emphasizing the acquisition, transformation, registration, and transmission of information in response to requests. The method involves searching the distributed ledger and information accumulation server using retrieval keys, transforming private information into hash values, and comparing these values to ensure accuracy before transmitting data to requesters. By following this method, the information provision system can securely manage and provide access to public and private information, safeguarding against falsification and ensuring the integrity of the data exchanged.
