A Cryptographic System Based on Blockchain and Attributes For Sharing Medical Data

Medical information contains a great deal of personal data and is quite sensitive to privacy concerns. Given the increasing volume of information in the healthcare sector, medical data must be appropriately and safely kept in this big data era. However, sharing current medical information can be risky and challenging because of the potential for privacy violations. To solve these issues, this study proposes a blockchain framework-based storage solution for healthcare information security along with attribute-based access control. The concept uses attribute-based access management to enable dynamic and granular access to medical data, which can be made secure and impenetrable before being stored in the blockchain system by creating related crypto contracts. 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.
