In the traditional electronic health record (EHR) management system, each medical service center manages their own health records, respectively, which are difficult to share on the different medical platforms. Recently, blockchain technology is one of the popular alternatives to enable medical service centers based on different platforms to share EHRs. However, it is hard to store whole EHR data in blockchain because of the size and the price of blockchain. To resolve this problem, cloud computing is considered as a promising solution. Cloud computing offers advantageous properties such as storage availability and scalability. Unfortunately, the EHR system with cloud computing can be vulnerable to various attacks because the sensitive data is sent over a public channel. We propose the secure protocol for cloud-assisted EHR system using blockchain. In the proposed scheme, blockchain technology is used to provide data integrity and access control using log transactions and the cloud server stores and manages the patient’s EHRs to provide secure storage resources. We use an elliptic curve cryptosystems (ECC) to provide secure health data sharing with cloud computing. We demonstrate that the proposed EHR system can prevent various attacks by using informal security analysis and automated validation of internet security protocols and applications (AVISPA) simulation. Furthermore, we prove that the proposed EHR system provides secure mutual authentication using BAN logic analysis. We then compare the computation overhead, communication overhead, and security properties with existing schemes. Consequently, the proposed EHR system is suitable for the practical healthcare system considering security and efficiency.

Abstract Background Forensic dental identification relies on the collection and comparison of antemortem and postmortem dental data and dental evidence. There are software solutions capable of archiving postmortem (PM) and antemortem (AM) data, with search and comparative tools which are user-centric and do not allow open search options and data mining of all dental related data, except through the use of coded data. This reduces interoperability and raises dental data incompatibility challenges. Blockchain technology could help introduce a trusted, secure, and holistic ecosystem in the electronic health record (EHR) system with a forensic interface accessed by experts in forensic pathology and forensic odontology for the purpose of identifying human remains and retrieve identifying data of compatible missing persons from the health and dental electronic record system, with the further advantage of protecting data breaches, redundancies, inconsistencies, and errors. Blockchain technology, and a forensic chain, can enhance forensic data management and human identification process by managing the missing person lists, create AM data repositories as shared data with the EHRs of living individuals, create PM data repositories of recovered from identifying autopsies unidentified persons, and support the preliminary comparison of compatible biological profiles during the final reconciliation phase. Conclusion In this hypothesis, author investigates possible applications of blockchain technology as a holistic technical and interoperability solution for managing both health/dental data for a medical as forensic human identification use.

Blockchain technology has the potential to transform healthcare delivery by facilitating data sharing between providers and electronic health record (EHR) systems. However, significant roadblocks stand in the way of widespread implementation of this technology across the healthcare industry. Our blockchainbased data-sharing solution addresses two of the most critical challenges associated with using blockchain for health data sharing: protecting sensitive health information and deploying and installing blockchain software across diverse hospital environments. Since transparency is a fundamental feature of blockchain, we enabled user- and group-based secret sharing by adding purpose-built software that leverages a collection of well-established cryptographic algorithms. To streamline deployment, we built a containerized solution that guarantees portability, simplifies installation, and reduces overhead maintenance costs associated with administration. To ensure ease of implementation in a hospital system, we designed our blockchain solution using a distributed microservices architecture that allows us to encapsulate core functions of our system into isolated services that can be scaled independently based on the requirements of a particular hospital system deployment. As part of this architecture, we built core components for securely handling cryptographic secrets, interacting with blockchain nodes, facilitating large file sharing, enabling secondary-index based lookups, and integrating external business logic that governs how users interact with Smart Contracts. The innovative design of our blockchain solution, which addresses critical data security, deployment, and installation challenges, provides the healthcare community with a unique approach that has the power to connect providers while protecting sensitive data.
