An End-to-End secured Blockchain framework for Internet of Things based smart Healthcare

Supply chain challenges can be overcome by using the latest technology, Blockchain, which is exploding in popularity. The decentralised, distributed nature of the blockchain enables enormous networks of independent, decentralised individuals and organisations to grow and operate with ease. Immutable, transparent, and kept in a distributed ledger using consensus methods, the data in the blockchain can't be altered. There has been a huge increase in the amount of data generated by the Internet of Things, which connects millions of computers and sensors. As part of this study, researchers suggest a secure authentication and data access between Blockchain and IoT end-users. In the wireless transmission research field, scalability of network data transfer is a major topic. The integrity, data quality, and originality of the data on the transmission line must all be maintained. To provide a secure route of communication, this paper investigates the use of Blockchain terminology for file sharing. A clustering infrastructure is used to forecast the internal correlation of bounded nodes and peers. Secure data flow between producers, suppliers, and customers becomes critical in this context in order to maintain responsiveness to market fluctuations. That is why this study is focused on introducing a privacy-preserving approach to data transmission. There are two techniques recommended for privacy preservation: Data Sanitization and Data Restoration. The original data is cleaned before transmission via blockchain technology, and the data is transformed into sanitised data. SCM data exchange with block chain technology will be tested by comparing it with traditional methods in terms of security.
