Application: Data management system, data management method, and data management program (Patent ID: US20240031131A1)
The patent filed by Denso Corp describes a data management system that utilizes blockchain technology to store original data and verify if it has been tampered with. The system includes a storage device for the original data and at least one node storing a blockchain. The processor in the node selects a hash function from a list, acquires a hash value of the original data, and stores it along with hash function identification information on the blockchain. This allows for verification of data integrity by comparing the original hash value with a verification hash value obtained using the same hash function.
Furthermore, the system includes provisions for acquiring the original data corresponding to a request, verifying its integrity by comparing hash values, and providing the data if it has not been tampered with. The method also involves storing the original data in association with the original hash value and utilizing an external hash value calculation device for hash value calculations. Additionally, the patent includes claims for a data management method and a non-transitory computer readable storage medium storing a program that enables the processor to store, select hash functions, acquire hash values, and store hash function identification information on the blockchain. Overall, the patent outlines a comprehensive system for secure data management and verification using blockchain technology.
