Privacy-Preserving Data Sharing in Decentralized Environments using Blockchain Technology

Thesis Abstract

Abstract


Decentralized data sharing offers numerous benefits but raises significant privacy concerns. This research focuses on the utilization of blockchain technology to enable privacy-preserving data sharing in decentralized environments. The study begins with a comprehensive review of decentralized data sharing, privacy challenges, and existing approaches. A detailed methodology for privacy requirements analysis, blockchain platform selection, and smart contract design is presented. The implementation phase involves the development of a privacy-preserving data sharing framework, integration of smart contracts for access control, and performance evaluation. The results are analyzed, compared with traditional methods, and visualized to demonstrate the privacy enhancements achieved. The thesis concludes with a summary of research contributions, implications, and recommendations for future work in the field of privacy-preserving data sharing in decentralized environments. This research is expected to provide valuable insights and practical solutions for addressing privacy concerns in decentralized data sharing using blockchain technology.
