Electronic Health Record Monitoring System and Data Security Using Blockchain Technology

Abstract

Bangladesh should have owned a decentralized medical record server. We face a lot of issues, such as doctor’s appointments, report organization in one spot, and report follow-ups. People now bring a large number of papers to the doctor’s chamber. They carry prescriptions, reports, and X-ray files, among other things. It complicates everyone’s life as a result. All of the reports must be reviewed by doctors on a regular basis. It is difficult to read old reports on a regular basis, and patients do not receive the correct medications or treatment. Doctors also find it extremely difficult to comprehend handwritten prescriptions. Data security, authenticity, time management, and other areas of data administration are dramatically improved when blockchain (smart contract) technology is linked with standard database management solutions. Blockchain is a groundbreaking, decentralized technology that protects data from unauthorized access. After smart contracts are implemented, the management will be satisfied with the patients. As a result, maintaining data privacy and accountability in the system is tough. It signifies that the information is only accessible to those who have been authenticated. This study focuses on limiting third-party engagement in medical health data and improving data security. Throughout the process, this will improve accessibility and time efficiency. People will feel safer during the payment procedure, which is the most significant benefit. A smart contract and a peer-to-peer encrypted technology were used. The hacker will not be able to gain access to this system since this document uses an immutable ledger. They will not be able to change any of the data if they gain access to the system. If the items are found to be defective, the transaction will be halted. Transaction security will be a viable option for recasting these problems using cryptographic methodologies. We developed a website where patients and doctors will both benefit because of the use of blockchain technology to ensure the security of medical data. We have different profiles for doctors and patients. In the patient profile, they can create their own account by using a unique address, name, and age. This unique address will be created from the genesis block. The unique address is completely private to the owner, who will remain fully secure in our network. After creating an account, the patient can view the doctors’ list and they can upload their medical reports such as prescriptions and X-rays. All the records uploaded by the patient will be stored on our local server (Ganache). The records are stored as hashed strings of the data. Those files will also have a unique address, and it will be shown in the patient profile. After granting access, the doctors will be able to view their records in the respective doctor’s profile. For accessing the options such as uploading, viewing, or editing the data, Ethereum currency (a fee) will have to be paid in order to complete the request. On the other hand, doctors can enter their profile using their name and unique address. After logging in, they can view their name, unique address, and the list of patients that have granted access to the doctor to view their files. On our website, the front end is handled by JavaScript, ReactJS, HTML, and CSS. The backend is handled by Solidity. Storage is handled by Ganache as the local host. Finally, this paper will show how to ensure that the procedure is as safe as feasible. We are also maintaining transparency and efficiency here.

Preserving the Privacy of Healthcare Data over Social Networks Using Machine Learning

“…Then, using the discovered vest node and the same principle to identify multiple vest accounts, the author can quickly identify multiple vest accounts. Assigning credibility levels to other nodes using the Sybil Rank algorithm [ 4 ] involves using the random walk algorithm. According to the standardized and degree value findings, the nodes with a lower credibility value are placed at the bottom of the list.…”

“…Among them, abnormal users are one of the standard methods criminals use to attack healthcare social networks. For example, merchants distort product value orientation for commercial interests [ 1 – 3 ]; criminals use multiple vests to deceive Internet users, steal information, or even online fraud [ 4 – 6 ]. According to statistics, the types of abnormal users also show a variety of forms due to different types of healthcare social networks.…”

Survey on Security and Interoperability of Electronic Health Record Sharing Using Blockchain Technology

“…We compiled findings on the various privacy-preserving EHR approaches and evaluated their effectiveness. The data access times and storage costs are relatively high compared to the other existing approaches but considering the data privacy, security, data integrity and interoperability factors, the use of blockchain could be a significant approach for healthcare systems (Akhter Md Hasib et al, 2022;Chelladurai and Pandian, 2022;Mantey et al, 202;Mahajan et al, 2022;Watford et al, 2019).…”

“…They are the on-premise approach (Loukides et al, 2014;Fan et al, 2018;Guo et al, 2018;Xia et al, 2017), the cloud-based approach (Tu et al, 2010;Hamid et al, 2017;Li et al, 2013;Liu et al, 2015) and the blockchain-based approach (Akhter Md Hasib et al, 2022;Chelladurai and Pandian, 2022;Mantey et al, 2022;Mahajan et al, 2022).…”

Analysis of Blockchain in the Healthcare Sector: Application and Issues

“…The present paper presents a thorough examination of the aspects and issues concerning the use of blockchains in EHRs. For example, Alla et al (2018) [60] indicated that the patient could lose control across the prevailing EHRs in the course of live actions, despite the fact that the service provider constantly retains the principal stewardship.…”
