Abstract

Data sharing is pivotal in sectors such as healthcare, finance, and social networking. Encrypting sensitive data, while essential for privacy protection, introduces complexity to data sharing and poses privacy risks when leveraging cloud servers. Blockchain-based searchable encryption offers a balance between privacy preservation and data availability; however, user anonymity remains a significant concern. Traditional storage systems, which rely on centralized servers, limit data stability and scalability. To address these challenges, we have introduced BISE, a solution that leverages the power of blockchain to achieve data integrity, using searchable encryption for secure searches and IPFS for decentralized storage. Constructed on Hyperledger Fabric and IPFS, our system demonstrates efficiency through simulations. This integrated approach ensures data privacy, integrity, and availability, with efficient updates and queries, making it a robust solution for sensitive data sharing in various domains.
