Abstract

With the advancement of cloud computing, data storage, and security have become crucial. The growing adoption of cloud services by companies, accompanied by increased threats from cybersecurity, highlights the importance of privacy and ownership of user data. Between 2022 and 2023, there has been an increase of around 48% in cloud security threats, emphasizing the urgent need for strong security solutions. To face these challenges, in this project, we propose integrating the Ethereum network's blockchain technology with a database located in the PostgreSQL cloud. The proposed solution aims to provide bidirectional data synchronization and strict control of access mechanisms. Blockchain technology ensures immutability and transparency of transactions, while PostgreSQL provides efficient and scalable storage. Through rigorous testing in an adaptive traffic control scenario, the results obtained indicate that this solution offers a significantly high level of security due to the decentralization of data, confirming that this solution is effective, and making it a powerful new option to improve security in cloud environments. In conclusion, the solution proposed in this project not only increases information security but also demonstrates the practical feasibility of integrating blockchain with cloud relational databases. This two-way alignment improves protection against cyberattacks and ensures that user data is protected from unauthorized access and malicious changes.
