A novel method to ensure the security of the shared medical data using smart contracts: Organ transplantation sample

Abstract

In recent years, the rapid development in information technologies appears in the form of digitalization, all of the processes in the health domain. Among the state‐of‐art, virtual reality, artificial intelligence, and blockchain technologies are among the most mentioned. In addition, the exponential increase in data kept in the electronic environment causes traditional central applications to face new challenges. The most important of these are accountability, transparency, security, cost, and time efficiency. In this study, a model based on blockchain technologies has been proposed to increase the transparency, accountability, and security of multi‐stakeholder shared medical data by using smart contracts (SCs). In the first part, there are briefly introduced the current situation of the health domain, blockchain technology, hyperledger fabric (HLF) and SCs. Afterward, in line with the latest technological developments, the studies carried out using the blockchain framework related to organ/tissue transplantation were examined. Lastly, the proposed framework was designed based on blockchain technologies for organ/tissue transplantation by using the HLF environment. The blockchain technology not only provides more visibility, more security, and better outcomes but also enables to store data securely and cheaply without allocating extra resources to a trusted authority. Thus, it can be ensured that the system is more transparent and more accountable.

Blockchain for Organ Transplantation: A Survey

“…As can be seen from Table 4, the majority of research that describes their platforms suggests adopting Ethereum (11 out of 17) [19,[57][58][59]61,64,66,67,70,75,76]. In the remaining six studies, three adopted Hyperledger Fabric [56,65,72], one used Monero [69], and two did not specify the platform they used [68,71]. A recently published study [69] suggested a biometric authentication protocol that permits data processing and storage in an encrypted manner when integrated into a blockchain that is based on a cryptocurrency that prioritises privacy.…”

“…As can be seen in Table 4, eight out of ten research studies that discuss blockchain encourage utilising private blockchain [56,58,59,65,67,72,75,76], whilst the other two studies suggest using public blockchain [19,58]. Users have a definite advantage when using a private blockchain because of its improved security, easier authentication, and scalability.…”

Blockchain-Based Medical Decision Support System

“…The blockchain-based MDSS may be presented in the form of the formal system: Medical Decision Support System/Model/Method 1 2 3 Blockchain-based framework for organ and/or tissue transplantationframework for organ and/or tissue transplantation by using the fabric hyperledger environment [11] + + Private Ethereum blockchain-based end-to-end organ donation and transplantation system, which provides organ donation and transplantation management, guarantees the fairness and efficiency of the organ allocation process and patients' trust enhancing [22] + + Secured-smart blood and organ donation web developed blockchain-based system, which is transparent and only available only by authorized users by Ethereum Smart Contract [23] + + Blockchain-based organ allocation algorithms on the examples of kidney allocation for solving some of the existing issues in the area of organ donation -different organ allocation policies and guidelines in different countries, storing of data from stakeholders and the matching patients in the central point, etc. [24] + + Machine learning-based classification models for predicting the success of intrauterine insemination therapy [25] + The different components of artificial intelligence were used for selection of the embryos with high implantation potential and with proper ploidy status, for prediction of later embryo development, and for increase of pregnancy and live birth rates, i.e.…”

CovidBChain: Framework for access‐control, authentication, and integrity of Covid‐19 data

“…The authors also raise their concern about social division due to immune and unimmune people. The authors proposed a blockchain‐based data‐sharing approach in Reference 22 that offers the blockchain's reliability, integrity, and decentralization properties. The proposed framework was designed based on blockchain technologies for organ/tissue transplantation by using the Hyperledger Fabric environment.…”
