Blockchain-Based Academic Information System to Enhance Data Security

Abstract

In the rapidly evolving digital era, educational institutions face significant challenges in managing and securing academic data. Academic data, which includes sensitive information such as student records, faculty details, grades, and attendance, is vulnerable to risks like theft, fraud, and information leakage. This research aims to develop and implement a blockchain-based academic information system to enhance data security and transparency in educational institutions. The research method used is Rapid Application Development (RAD), which allows for quick software development through rapid iterations and active user involvement. The research stages include requirements planning, system design, construction, and implementation and testing. The developed system is designed to store academic data on an encrypted blockchain ledger, with each data change recorded as a new, immutable transaction. The research results show that the implementation of blockchain technology is effective in maintaining the integrity and security of academic data. The system can prevent data manipulation through cryptographic mechanisms, hashing, and consensus. Additionally, transparency in academic data management is increased, allowing all authorized parties to verify data in real-time without third-party involvement. System testing shows a significant improvement in academic data security compared to traditional centralized systems. The evaluation of transparency and user satisfaction levels also indicates that this system provides a positive experience and meets user needs in various aspects. Overall, this research confirms that blockchain technology can be an innovative solution to address the challenges of academic data security and transparency in educational institutions, providing significant benefits to all stakeholders.
