Healthcare Based Block Chain Survey In IOT

Because block chain technology can improve distributed systems' security, dependability, and resilience, it has been gaining popularity. Research based on this technique has helped a number of fields, including data analysis, finance, remote sensing, and healthcare. The primary characteristics that make block chain technology appealing include distributed ledgers, decentralization, privacy, transparency, and data immutability. However, because there is a chance of a privacy breach, medical records that hold private patient information make this system extremely complex. The purpose of this project is to investigate block chain applications in the healthcare sector. We also include articles that touch on other topics, like the Internet of Things, information management, medicine supply chain tracking, and privacy and security issues. Lastly, we aim to investigate block chain concepts in the medical field by evaluating their advantages and disadvantages and providing direction to other studies in the field. We also provide a summary of the Block chain's techniques. Index Terms—IoT, Block Chain, Healthcare, Smart Contract, Etherum.
