Evolutionary Survey On Data Security In Cloud Computing Using Blockchain

In recent times, data has become an inevitable factor in cloud computing. The word data eventually seeks its issue on privacy and security. With the rise of new technologies, the need for data storage has increased. Massive increase in the datasets has led to the evolution of cloud storage. The benefits of cloud computing are immense, but on the contrary there is an increasing risk to the security of the data stored in the cloud. This paper deals with a survey on the security issues which highlights the effectiveness of security that has been implied in the forms of cloud computing and blockchain technologies. The survey also includes a deep understanding of a PoW–based blockchain model using the blockchain technology. The idea behind this work is to provide a detailed survey about the blockchain technology which is growing tremendously.
