Abstract: Cloud computing is a widely recognized and established method. A vast number of individuals worldwide depend on cloud computing as a means to exchange data and securely store information. However, one of the prime concerns is security of the data over the cloud for storage and access purposes. Currently, the usage of blockchain technology has become a prevalent innovation that may effectively address security issues in cloud computing. It is a distributed data management platform that ensures confidentiality, privacy, and data integrity without the need for any intermediate organization. This research paper aims to integrate blockchain's inherent security features with data anonymization techniques to enhance cloud security and privacy. One other factor that is important is the trust among the entities that are involved during the process of cloud security through blockchain. The amalgamation of these technologies could revolutionize how sensitive data is protected in the cloud, offering a more secure and private environment. In this paper, comprehensive literature work pertaining to cloud security has been elaborated in consideration to the blockchain techniques utilization along with the anonymization methods. Data anonymization provides privacy by concealing identifying information; however, achieving a balance between privacy and data usefulness is complex, which motivates the work in this context. The main contribution is the comprehensive comparative evaluation and analysis of the reviewed literature while considering parameters like throughput, privacy, cost, scalability, performance, and reliability towards the blockchain based approaches for cloud security along with factors such as anonymity type, differential privacy and orientation of the approach in the anonymization side. Moreover, statistical evaluation of the studies has been done based on the inferences drawn. This paper also highlights the current research challenges for future works.
