BLOCKCHAIN-BASED EXPENSE PROCESSING DATA MANAGEMENT SYSTEM AND METHOD AND COMPUTER PROGRAM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/071650
Kind Code:
A1
Abstract:
A blockchain-based expense processing data management system may comprise: a transmitting/receiving unit configured to receive expense processing information including card transaction information and expenditure proof information from an expense user's user device or an external server; a hash extracting unit configured to generate a hash value corresponding to the expense processing information; a data processing unit configured to divide the card transaction information into financial information, personal identification information, and general transaction information, and divide the financial information and the personal identification information into a plurality of partial data; a transmitting unit configured to upload the plurality of partial data and the hash value to a blockchain network; and a storing unit configured to store the general transaction information and the expenditure proof information. Using the expense processing data management system, it is possible to reduce the load and cost required to ensure security when providing expense processing data to a user by dividing the main information of the expense processing data into several data pieces, distributing and storing them on the blockchain network, and allowing the user to download corresponding information from the blockchain network.
