Decentralized Healthcare Management System Using Blockchain to Secure Sensitive Medical Data for Users

Abstract

AbstractHumans used machines that run manually to meet their needs. Nowadays, humans can interact with smart machines that perform tasks both manually and automatically, including work-related tasks. The growth of smart machines is increasing rapidly over a short period of time. Smart machines can work under certain protocols. The fundamental concept of smart machines is that they perform activities allocated to them. There are two types of smart machines: wired machines and wireless machines. Wired machines run their best; on the other hand, there are some issues with wireless machines. They failed to develop a permanent and private network, as well as provide data protection. Researchers consider this as a serious issue, so they partnered up with the industry sector and created an application to solve this issue. The application solution is “blockchain.” Blockchain is a process of actually collecting and growing the record list that gets interconnected with the help of certain protocols of cryptography. Every block contains a hash that is generated by associating with the previous block using transition data with a timestamp. Blockchain provides the public, private, consortium, and hybrid blockchains a wide range of built-in features. The scope of the industry sector is that the application can be used for a variety of purposes, such as security, transactions, and capability. And also this sector can also lead to practical applications such as healthcare management system. Blockchain applications in the healthcare management system require record sharing with efficient data interoperability and authentication. After building this application, we can use it for fraud detection, verification, and identification among others. Before, all systems built in the healthcare system were well-organized, but the problem was a lack of stringent authentication. The existing systems also focus on the healthcare system, but the problem is that there is no security for patient data as confidential medical records are moved from one hospital to another for specialized treatments. In this proposed system, we can build this application using blockchain with stringent authentication. By considering this problem, we can propose the ADS application. SADS stands for stringent authentication and decentralized storage using blockchain. Stringent authentication is the process of providing high security protocols to the network using cryptographic SHA-256 hash algorithm. This application can be implemented using Ethereum blockchain technology. Decentralized storage is utilized for blockchain. Decentralized storage is where breaking up of storage records takes place from one major server to multiple servers. This allows easy access to medical information and also helps to further research.KeywordsSmart machinesBlockchainCryptographyHealthcare systemIndustry sectorAuthenticationEthereum blockchain technologyDecentralized storage
