Comprehensive Review for Big Data-Based Sensitive Information Secure Sharing Using Blockchain Techniques

Big Data (BD) has attracted much attention from science and industry. Recent developments in BD have raised significant security issues and increased the risk of BD data privacy breaches. The novel reviews recent research and advancements in sensitive data security and privacy. This review explores various blockchain services for BD, including blockchain for securing significant data acquisition, data storage, analytics, and privacy protection. It then discusses recent approaches to Blockchain based privacy preservation techniques and reviews consensus algorithms and various other cryptographic methods like Ciphertext-Policy Attribute-Based Encryption (CP-ABE), Elliptic Curve Cryptography (ECC) and Enhanced Privacy-Preserving Data Perturbation Algorithm (EPPDPA). Finally, discuss the accomplishments and drawbacks of recent methods, as well as highlight investigation open issues associated to the incorporation of blockchain into BD.
