Blockchain in the Healthcare Domain and Performing Various Security Analysis

Blockchain is a promising technology that can be used to improve the healthcare system. It can be used to store patient data securely and prevent tampering. It can also be used to improve supply chain management by increasing transparency and interoperability. This work proposes a web-based application that uses blockchain to store patient’s data and retailer’s information. The application will also be able to send encrypted messages securely and anonymously. The application will be deployed on the Ethereum platform. The benefits of using blockchain in healthcare are Security: Blockchain is a secure way to store data because it is decentralized and encrypted. This makes it difficult for unauthorized users to access or tamper with data. Transparency: Blockchain is transparent, which means that all transactions are recorded on the blockchain and can be viewed by anyone. This can help to increase trust and accountability in the healthcare system. Interoperability: Blockchain can be used to connect different healthcare systems together, which can improve the flow of information. This can help to improve patient care. Immutability: Blockchain is immutable, which means that data cannot be changed once it is added to the blockchain. This can help to ensure the accuracy of data. The challenges of using blockchain in healthcare are Complexity, Cost, and Regulation. Despite these challenges, blockchain is a promising technology that has the potential to improve the healthcare system. This work is a step towards realizing the potential of blockchain in healthcare.
