Abstract

This study looks into the role blockchain technology can play in improving the safe sharing of data between various parties in emergency management. It seeks to explore how blockchain, coupled with attribute-based access control, can address the issues in centralized data platforms and transform the nature of decentralized data governance. The five core research questions focus on improving data security and privacy, the role of ABAC in dynamic policy adaptation, data sharing efficiencies and reliability, minimizing risks of single-point failures and unauthorized access, and the feasibility of using Hyperledger Fabric for real-world applications. By applying a quantitative research approach, the study assesses how blockchain and ABAC can influence data security, policy adaptation, and system reliability in emergency management. The results are confirmed in terms of significant improvements in data security due to blockchain; the ease of dynamic policy adaptation; better efficiency in sharing data; risk mitigation; and validation of the feasibility of using Hyperledger Fabric for applications in emergency management. This research contributes to the understanding of decentralized data governance and underscores the importance of blockchain in enhancing emergency response systems.
