Combining Blockchain and Relational Database Management for Secure Accounting Information System
The Accounting Information System(AIS)serves as a core module in Enterprise Resource Planning(ERP).Traditionally designed as a centralized system,AIS exhibits drawbacks such as single points of failure,scalability is-sues,security concerns,and lack of flexibility.To address these challenges,we propose a distributed AIS system that integrates Consortium Blockchain and Relational Database Management System(RDBMS),providing support for tamper-proof transactions and authenticaions.By embedding blockchain within relational tables,we store trustworthy informa-tion in the database in an anti-tampering manner,enabling data traceability and verification.The entire system is col-laboratively maintained by multiple authorized participants,ensuring secure integration of AIS data and explicit data ownership through a dual-signature scheme.To support large-scale queries,an optimization algorithm based on Dy-namic Bloom Filter Tree(DBFT)has been applied,aiming to minimize the overall time cost of query and verification operations.The experimental evaluation indicates that the proposed method has successfully implemented blockchain-based identity verification and tamper tracing in the AIS system,leading to a significant enhancement in the efficiency of large-scale analytical queries and verifications.
