Information Technology (IT) services have become an inherent component in almost all sectors. Similarly, the health sector has been recently integrating IT to meet the growing demand for medical data exchange and storage. Currently, cloud has become a real hosting alternative for traditional on-permise software. In this model, not only do health organizations have access to a wide range of services but most importantly they are charged based on the usage of these cloud applications. However, especially in the healthcare domain, cloud computing deems challenging as to the sensitivity of health data. This work aims at improving access to medical data and securely sharing them across healthcare professionals, allowing real-time collaboration. From these perspectives, they propose a hybrid cryptosystem based on AES and Paillier to prevent the disclosure of confidential data, as well as computing encrypted data. Unlike most other solutions, the proposed framework adopts a proxy-based architecture to tackle some issues regarding privacy concerns and access control. Subsequently, this system typically guarantees that only authorized users can view or use specific resources in a computing environment. To this aim, they use eXtensible Access Control Markup Language (XACML) standard to properly design and manage access control policies. In this study, they opt for the (Abbreviated Language for Authorization) ALFA tool to easily formulate XACML policies and define complex rules. The simulation results show that the proposal offers simple and efficient mechanisms for the secure use of cloud services within the healthcare domain. Consequently, this framework is an appropriate method to support collaboration among all entities involved in medical information exchange.

Introduction. The development of effective digital medicine tools is an intensive and complex process that requires the interdisciplinary efforts of a wide range of experts, from scientists and engineers to ethics experts and lawyers. Digital medicine products have great potential for improving medical measurement, diagnosis and treatment. One of the main challenges for the healthcare sector is to address the issue of fast, convenient and secure exchange of information about patients’ health. Service-oriented architectures of such products may accomplish many of the challenges facing healthcare systems. The purpose of the paper is to develop an information and software module ExchangeDMD to ensure the accumulation, storage and exchange of diagnostic medical data in accordance with modern medical information standards to maintain the interoperability function as one of the leading principles of digital medicine. Results. A special adaptive architecture of digital medicine infrastructure has been developed, which enables an integrated solution of data exchange between participants of providing medical services, which is carried out with the help of web services. The specifics of different types of medical information are analyzed and taken into account in accordance with the access regime for its processing. The module structure has been developed and implemented in software, which has three main levels: central virtual storage (virtual data center to implement certain functions), remote administration segment (technical support and administration network) and user segment (mobile devices and user-patient applications). Conclusions. The ExchangeDMD information and software module is designed to ensure the accumulation of patient data, integration between the various units within the system, as well as to ensure the management of this data by health care personnel. The ExchangeDMD module is built using the international standard HL7 CDA, which enables formalizing electronic medical records using RIM (information model links) to attract the necessary directories and classifiers when creating medical records and documents.

Electronic Medical Record (EMR) is basically the digital equivalent of paper records, or charts at a clinician’s office. EMR assist and make easier the services rendered by a wide range of medical practitioners such as physicians, nurses, pharmacists and many others, hence, increasing the safety of patients. It's importance in the health sector cannot be overemphasized. The designed framework aims at identifying security challenges in the use and adoption of EMR, to design and implement a framework that will address issues identified in the use and adoption of EMR. This study presented a security framework to improve the security and privacy issues of EMRs by adopting Role Based Access Control and RSA cryptography. Role Based Access Control (RBAC) model was used because of its flexibility to support minimal functionality and its simplistic mode of assigning roles and permissions to users. In conclusion, this research was able to improve the security of EMRs and hence will increase its acceptance by health institutions which will bring about improved health services, especially in developing countries were manual record system are still prominent.

Internet of Medical Things (IoMT) is a kind of Internet of Things (IoT) that includes patients and medical sensors. Patients can share real-time medical data collected in IoMT with medical professionals. This enables medical professionals to provide patients with efficient medical services. Due to the high efficiency of cloud computing, patients prefer to share gathering medical information using cloud servers. However, sharing medical data on the cloud server will cause security issues, because these data involve the privacy of patients. Although recently many researchers have designed data sharing schemes in medical domain for security purpose, most of them cannot guarantee the anonymity of patients and provide access control for shared health data, and further, they are not lightweight enough for IoMT. Due to these security and efficiency issues, a novel lightweight privacy-preserving data sharing scheme is constructed in this paper for IoMT. This scheme can achieve the anonymity of patients and access control of shared medical data. At the same time, it satisfies all described security features. In addition, this scheme can achieve lightweight computations by using elliptic curve cryptography (ECC), XOR operations, and hash function. Furthermore, performance evaluation demonstrates that the proposed scheme takes less computation cost through comparison with similar solutions. Therefore, it is fairly an attractive solution for efficient and secure data sharing in IoMT.

BACKGROUND Blockchain is a distributed storage technology that provides a powerful tamper-proof technique through a distributed ledger and decentralized network. Initially, blockchain was primarily used for cryptocurrency in the financial field. However, it has attracted attention in various fields such as media, logistics, and medical care. Notably, various studies are being conducted to use blockchain in the medical field, where data reliability and integrity are essential. Representative medical blockchain research includes decentralized medical system design, secure data sharing schemes, and access control for privacy-preservation while sharing electronic medical records (EMRs). OBJECTIVE Our goal is to design a blockchain-based EMR sharing system that provides high reliability and scalability so that electronic medical records can be shared safely and efficiently. The system protects patients' privacy in medical data through a medical information exchange process that includes data encryption and access control. METHODS We propose a blockchain-based EMR sharing system that allows patients to manage the medical records scattered across multiple hospitals and share them with other users. Our patient information exchange (PIE) chain protects the patient's EMR from security threats such as counterfeiting and privacy issues during data sharing. Also, it guarantees high scalability by using distributed data sharing methods to share regardless of the size or type of EMR quickly. To check the proposed system's performance, we performed a simulation of the EMR sharing process and compared it with previous works on blockchain-based medical systems. RESULTS The simulation model is implemented using Hyperledger Fabric, an open source blockchain framework. Experimental results show that it takes an average of 10.1 ms to download 1MB of EMR on the proposed system. Moreover, it provides high scalability as it can rapidly share various data, regardless of size and type. The proposed system proposes a distributed ledger structure and a security level-based access control scheme to prevent data forgery attacks by a malicious user and unauthorized access. Moreover, it ensures high reliability by preventing data loss and privacy leakage due to sniffing and spoofing attacks with a data re-encryption scheme. CONCLUSIONS This paper proposes the PIE system, a Medical system that guarantees high reliability and scalability. The PIE system protects the EMR of the Patient created in the medical service process from threats such as personal information leakage and forgery. Through the distributed data sharing process based on blockchain, the EMR of the Patient can be quickly shared regardless of the data size. Our contribution paves the way for a patient-centered EMR sharing environment to integrate and manage patient medical information through the proposed blockchain-based Medical system.

Cloud computing is one of most fast developing technology and many organizations are now offering a wide range of cloud services. Although the services provided are the same there is no common programming language, technology and protocol to access the entirety of the cloud services. Client who use a service provided by a certain organization are often limited and confined to that specific organization its structure and technologies. A Cloud federation is one solution to that interoperability through which computing resources of one Cloud Service Provider is rented or sold to another service provider or the services provided by one Cloud Service Provider is replicated into another Cloud Service Provider without having to lose any functionality and performance. This process is a tedious task and is prone to multiple limitations. In this paper we proposed the architectural framework and algorithm for the possible interoperability between the cloud service providers based on SLA in prospective of health sector as the application of cloud in health sector is highly needed in future.

In the past years, the Internet of Things (IoT) used in different applications and very wide range of fields (e.g. cloud services, smart environments, logistics, social and personal domains, and healthcare services). The IoT included a variety of components and devices such as RFID devices, wireless sensors, actuators, and wireless networks. Also, the IoT with smart devices adopted in various companies, organizations and public services systems. For instance, some devices like Notebooks and smartphones have been used to perform different management activities and duties. These smart devices relied on data exchange and data storage resources in clouds computing services. In this context, the saved data and exchanged data required protection against hacking operations, transferred with more secure communications channels, and safe storage environment in the clouds and local storage systems. In this paper, we proposed some encryption algorithms to tackle the issue of data confidentiality in the IoT applications. This research provided analysis and investigation of these encryption algorithms in light of components of the designs, versions of these algorithms, encryption keys, block size, round functions and the techniques used in the designs.

On the basis of Internet of Things (IoT) technologies, Community Medical Internet of Things (CMIoT) is a new medical information system and generates massive multiple types of medical data which contain all kinds of user identity data, various types of medical data, and other sensitive information. To effectively protect users’ privacy, we propose a secure privacy data protection scheme including transmission protection and access control. For the uplink transmission data protection, bidirectional identity authentication and fragmented multipath data transmission are used, and for the downlink data protection, fine grained access control and dynamic authorization are used. Through theoretical analysis and experiment evaluation, it is proved that the community medical data can be effectively protected in the transmission and access process without high performance loss.
