Review on "Blockchain technology based medical healthcare system with privacy issues"

Healthcare has been the industry with the highest boom in terms of both revenue and data. With so much of electronic health records, the security has been the need of the hour. To make this critical information more secure, there has been an urge to use the blockchain technology. Therefore, researches came up with a solution of blockchain technology in medical healthcare that will not only protect data from being tampered but will also ensure that the data leakage is stopped. This technology could preserve data and thus guarantee reliability. And if this technology is used along with cloud computing technology, problems related to storage can also be vanished, because cloud is trusted for storing and managing data. Also, the blockchain can address the security issues of the cloud. Indeed, medical data sharing and storing with Blockchain-based cloud can address a lot of issues of medical data. The main aim of this paper is to present the current state-of-the-art on blockchain-based medical healthcare system. We have clearly discussed several existing works on the same domain and also presented a comparative study among the published works.
