Research on Security Storage and Access Control System of Big Data in Universities Based on Blockchain Technology

With the rise of the big data era, universities are encountering significant challenges in safeguarding data security and ensuring privacy protection. Blockchain technology, renowned for its decentralized, secure, and reliable distributed database features, offers a promising avenue for addressing the security and access control issues associated with big data in universities. Initially, this study examines the current state and prevalent challenges concerning the security storage and access control of big data within university environments. Subsequently, it provides an in-depth overview of blockchain technology and its potential application in enhancing data security within this context. Following this, a conceptual framework for a university-based big data security storage and access control system leveraging blockchain technology is proposed. This framework is elaborated upon, covering aspects such as data encryption, access control strategies, and consensus mechanisms. Finally, the efficacy and practicality of the proposed system in enhancing the security of big data storage and access control within universities are evaluated through experimentation, alongside an outlook on future research directions. This study aims to offer novel theoretical insights and practical guidelines for enhancing big data security storage and access control within university settings.
