Information related to the medical field is extremely sensitive to privacy issues and involves a lot of personal information. Medical data must be accurately and securely stored in this era of big data due to the growing amount of information in the healthcare industry. Sharing up-to-date medical data, nevertheless, can be difficult and dangerous due to the possibility of privacy breaches. This paper suggests access control based on attributes and the blockchain framework- based storage solution for healthcare information security to address these problems. Before storing medical data in the blockchain system, it may be made secure and impenetrable through developing associated crypto contracts, the plan leverages attribute-based access management to allow dynamic and granular access to that data. Moreover, IPFS technology is incorporated into this solution to ease the blockchain’s storage burden. Experiments demonstrate that the suggested system in this study, which combines Demonstrations reveal that the scheme proposed in this paperwork on the combination of access control of attributes and blockchain technology will not only takes care of the storage and uprightness of medical data but also have more productivity while accessing the medical information.
