Blockchain-enabled Data Governance for Privacy-Preserved Sharing of Confidential Data. (arXiv:2309.04125v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
In a traditional cloud storage system, users benefit from the convenience it
provides but also take the risk of certain security and privacy issues. To
ensure confidentiality while maintaining data sharing capabilities, the
Ciphertext-Policy Attribute-based Encryption (CP-ABE) scheme can be used to
achieve fine-grained access control in cloud services. However, existing
approaches are impaired by three critical concerns: illegal authorization, key
disclosure, and privacy leakage.
To address these, we propose a blockchain-based data governance system that
employs blockchain technology and …
