“…In most of the blockchain-based solutions, confidentiality is maintained using cryptographic tools to ensure that data is not readable by unauthorized users [100], [107], [131]. We found that most popular encryption algorithms are Attribute-based Encryption (ABE) [91], Proxy Re-Encryption (PRE) [90], and symmetric encryption (e.g., AES) [11]. Integrity of EHR data is all about consistency and completeness, and also refers to their safety.…”

Blockchain is the revolutionary invention of the twentieth century that offers a distributed and decentralized setting to communicate among nodes in a list of networks without a central authority. On the other hand, an electronic health records (EHRs) is the electronically stored health information in a digital format.EHRs are normally shared among healthcare stakeholders and facing power failure, data misuse, lack of privacy and security, and audit trail. Blockchain is a leading technology among others to address the limitations related to EHRs. It can provide a safer and secured decentralized environment for exchanging EHRs data. There are three categories of blockchain-based potential solutions have been proposed to handle EHRs: conceptual, prototype, and implemented. This study focused on a Systematic Literature Review (SLR) to find and analyze articles proposed either conceptual or implemented to manage EHRs using blockchain. The study analyzed 99 papers that were described from various publication categories. The deep technical analysis focused on evaluating articles based on privacy, security, scalability, accessibility, cost, consensus algorithms, and type of blockchain used. The SLR found that the blockchain technology is promising to provide decentralization, security, and privacy that traditional EHRs often lack. Moreover, results obtained from the detailed studies would provide potential researchers with a reference as to which type of blockchain to choose for future development. Finally, future research directions, in the end, would direct enthusiasm to combine new blockchain-based systems to properly manage EHRs.

“…Often, a third party who requests access to the owner of EHRs, follows a public-key encryption process [99]. For instance, ABE [91] allows third parties to get access rights from some attributes such as "doctor" and "hospital". Authorization is the process where a patient or hospital authorizes someone to get access to his EHRs.…”

Cloud computing has increased its service area and user experience above traditional platforms through virtualization and resource integration, resulting in substantial economic and societal advantages. Cloud computing is experiencing a significant security and trust dilemma, requiring a trust-enabled transaction environment. The typical cloud trust model is centralized, resulting in high maintenance costs, network congestion, and even single-point failure. Also, due to a lack of openness and traceability, trust rating findings are not universally acknowledged. “Blockchain is a novel, decentralised computing system. Its unique operational principles and record traceability assure the transaction data’s integrity, undeniability, and security. So, blockchain is ideal for building a distributed and decentralised trust infrastructure. This study addresses the difficulty of transferring data and related permission policies from the cloud to the distributed file systems (DFS). Our aims include moving the data files from the cloud to the distributed file system and developing a cloud policy. This study addresses the difficulty of transferring data and related permission policies from the cloud to the DFS. In DFS, no node is given the privilege, and storage of all the data is dependent on content-addressing. The data files are moved from Amazon S3 buckets to the interplanetary file system (IPFS). In DFS, no node is given the privilege, and storage of all the data is dependent on content-addressing.

“…The underlying blockchain technology network model provides a method of storing distributed data, ensuring the stability and effectiveness of the model network. Use encryption technology for digital signatures and highly encrypted account information to ensure data transmission [6] and secure access-CCP replaces third-party intermediaries [7] to provide technical support for trade security and user confidence. In the blockchain system, the data generated by the participants' transactions are packaged into a data block.…”

With the progress of economic globalization and human beings have entered the era of knowledge economy, the growth of enterprises is facing multi-level competition. With the increase of users' personal development, the diversity of needs puts forward higher requirements for enterprises in the face of a complex market environment. The purpose of this article is to cater to the needs of the times, to further expand and optimize its own information sharing model, and to propose a new supply information sharing management model based on embedded systems. Mainly use regional chain technology to conduct research in the following aspects, including the theoretical basis of regional chain and information sharing, and the comprehensive analysis and management of existing information sharing models in the supply chain. Through a comprehensive analysis of the data, this paper concludes that the values of AVE are all above 0.5, and the values of CR are all higher than 0.8, so it can be considered that the convergence validity of the model is good.
