Blockchain-Based Business Intelligence System Architecture for a Trusted Open Budget Initiative
Keywords:
Decision Support System, Data Warehouse, Blockchain, CryptographyAbstract
This paper presents an innovative decision support system architecture that integrates blockchain technology to ensure the authenticity, traceability, and non-repudiation of data in the context of public finance. In contrast to traditional architectures limited to ETL processes, data warehouses, application server, and user interfaces, this approach introduces a blockchain layer to secure datasets. The system generates a cryptographic fingerprint (hash) for each dataset, signs it with a private key, and records the pair (hash, hash_signed) within the blockchain. This design allows users to independently authenticate datasets using the public key, thereby guaranteeing data integrity even in the event of central server failure. The proposed architecture was implemented on Ubuntu 22.04, and the experimental results demonstrate the technical feasibility of this solution for critical decision-making systems requiring high availability and maximum confidence in data.
