SYSTEM AND METHOD FOR PROCESSING PERSONALLY IDENTIFIABLE INFORMATION BASED ON BLOCKCHAIN

摘要

The present invention relates to a blockchain-based personal information processing system and method, and when a smart contract is created between an information subject node having personal information and a third party node that provides a service required by the information subject, the smart contract is a blockchain system. When registering, and requesting a personal information request query from the third-party node to the blockchain system, the blockchain system checks the rules of the smart contract to determine whether to provide personal information. According to the present invention, since the personal information is controlled based on the terms recorded in the smart contract, it is possible to improve the controllability of the information subject to the personal information, and transaction processing of personal information (call history, usage history, etc.) By recording, it is possible to not only transparently check the personal information processing history, but also to track it if necessary. As a result, the rights of the data subject to personal information can be improved.
