Modern medicine has grown to an insurmountable level over the past decades. Today, this sector of human life is a high-tech industry, where all areas that can save lives of previously hopeless patients are successfully developing. The technical equipment of health care facilities has been substantially improved, it has become possible to diagnose diseases at an early stage and to quickly restore the working capacity of patients. Nevertheless, with all the advantages and capabilities of modern technology in this area, there are many problems. One of the most significant is the provision of privacy of medical information, which should be considered from both sides, both technical and regulatory. Ensuring the confidentiality of data in medical systems depends on the correct and timely organization of managing access to medical information. The US Health Insurance Portability and Accountability Act (HIPAA) is the most widespread and comprehensive regulatory document for the security of medical data. Regarding the Ukrainian normative documents, they realize the rights of the patient to receive information about their state of health, and medical systems do not have a certificate on the compliance of a comprehensive system of protection of information in accordance with the requirements of normative documents on the technical protection of information. In this article, the authors are considering designing an access control model that solves the problem of providing information security for medical systems and is based on access control based on roles with minimal constraints. The model to be developed should determine the actions and resources that are available to the user, as well as provide individual access to resources. The authors examined the existing models of access control, identified the advantages and disadvantages that formed the basis of their own model. The paper describes the creation of a role-based security policy that defines the information flows permitted by the system, based on the international regulatory document HIPAA. With the help of the developed model, it is possible to execute its storage in different ways and in any case, it is very easy to convert into a relational database

Purpose – In recent years, many development projects of the medical systems encounter difficulties and eventually fail. Failure is often due to very complicated and changeable medical procedures and the inconsistent understanding between system stakeholders, especially the healthcare providers, and information technology staff. Many research results also indicate that poor communication easily results in negative consequences during the implementation of the medical information system. To effectively overcome this obstacle, the purpose of this paper is to propose an enhanced Delphi method to assist in reaching consensus during the software development with some additional steps. Design/methodology/approach – As an alternative to the traditional way to elicit pertinent feedback from respondents, the enhanced Delphi method stresses the systematic, flexible, and cyclic stages to construct a questionnaire with viewpoints from different types of panelists and a self-assessment procedure as a validating step to measure the improvements in the system implementation. Findings – The better communication between the members of project team does increase the comprehensive assessment of a project. Originality/value – Based on a practical case, the enhanced Delphi method really demonstrates good performance and effectiveness.


The medical environment, combined with IT technology, is changing the paradigm for medical services from treatment to prevention. In particular infrastructure technologies such as big data and internet of things are being used in conjunction with the cloud as ICT convergence digital healthcare technology is applied to hospital medical systems. In particular, as medical services are used with IT devices, the quality of medical services is increasingly improving to make them easier for users to access. Medical institutions seeking to incorporate IoT services into cloud health care environment services are trying to reduce hospital operating costs and improve service quality, but have not yet been fully supported. In this paper, a patient information collection model from H-IoT(Hospital IoT)_system, which has established a cloud environment, is proposed. The proposed model prevents third parties from illegally eavesdropping and interfering with patients' biometric information through IoT devices attached to the patient's body at hospitals in cloud environments that have established H-IoT systems. In the proposed model, patients are now eligible for medical service by installing an IoT device, and medical staff can analyze patient disease information so that patients who visit the hospital can collect and receive treatment for diseases related to their eating habits. The disease information analyzed in the proposed model minimizes hospital work to facilitate the treatment and management of prescriptions according to the degree of disease in patients. On average, the time required for medical staff to collect and analyze IoT patient information was 7.8 percent lower than previous techniques. The results of 11.1% improvement in server efficiency for processing IoT patient information were obtained. The IoT medical information transmitted from IoT devices was 16.3% lower than the traditional technology, using diffusion band technology

Abstract:DIOGENE 1 has been a mainframe-based centralised HIS with a star network of communication operating on a daily basis with 120 nursing ward units since 1978. Together the limited and costly growth capabilities of such a system with its extreme difficulty in cooperating jointly with other heterogeneous medical systems, with the need for faster networking expansions, led to the new design of a distributed architecture called DIOGENE 2. In 1989, a migration process between DIOGENE 1 and DIOGENE 2 was initiated and is now on the verge of being achieved. During the time of this new expansion of the HIS, it has been easy to cooperate with the decentralisation process of the new hospital organisation as well facilitating the integration of new functionalities like i.e. new WIS architectture, medical office patient histories, integration based upon PCs with UNIX based client/server platforms. That approach combines the handling of paragraphs structured patient records with the use of medical natural language processing and semi-automatic encoding as well. Amongst these new functionalities the P ACS are associated with image manipulation platforms called OSIRIS for X-Ray images as well as other tools devoted to molecula biology and genetics up to the ExPASy server on Internet using WWW Mosaic which is accessible from all over the world. The distributed architectture appears well suited not only for the integration of these new functionalities but to keep them growing as smoothly as possible.

Telemonitoring is not a new term, in information technology (IT), which has been employed to remotely monitor the health of patients that are located not in common places, such hospitals or medical centers. For that, wearable medical sensors, such as electrocardiography sensors, blood pressure sensors, and glucometer, have commonly been used to make possible to acquire the real-time information from the remotely located patients; therefore, the medical information is further carried, via the Internet, to perform medical diagnosis and the corresponding treatments. Like in other IT sectors, there has been tremendous progress accounted in medical sectors (and in telemonitoring systems) that changes the human life protection against several chronic diseases, and the patient’s medical information can be accessed wirelessly via Wi-Fi and cellular systems. Further, with the advents of cloud computing technology, medical systems are now more efficient and scalable in processing, such as storage and access, the medical information with minimal development costs. This study is also a piece of enhancement made to track and monitor the real-time medical information, bounded in authorized area, through the modeling of private cloud computing. The private cloud-based environment is designed, for patient health monitoring called bounded telemonitoring system, to acquire the real-time medical information of patients that resided in the boundary, inside medical wards and outside medical wards, of the medical center. A new wireless sensor network scenario is designed and modeled to keep or monitor the patients’ health information whole day, 24 hours. This research is a new secured sight towards medical information access and gives directions for future developments in the medical systems.

Abstract With the rapid development of medical information, the medical cyber system is rapidly transforming, and medical information sharing faces new challenges. Blockchain technology is a revolutionary technology. It has the characteristics of tamper-proof and privacy-preserving, and has natural protection for big data systems, that can be used in medical systems. In this paper,we proposed to store medical cyber physical data in a mixed blockchain with private blockchain and consortium blockchain in order to realize the secure storage of medical cyber physical data by the tamper-resistant and sharing of blockchain technology. In the system, a threshold signature system based on blockhain is also proposed. Aiming at the situation that medical accidents are easy to occur in multidisciplinary joint consultation in the medical process, this paper proposes to use threshold signature for joint consultation. Using the security and threshold of threshold signature, treatment can be carried out when the threshold number is reached, and medical data can be uploaded to the consortium blockchain. The security analysis and performance analysis show that the scheme has advantages in safety and performance and is suitable for the medical environment to a certain extent.

Most recent advances in the study of ancient Mesopotamian medical texts have disclosed information pertaining to the fields of diagnosis, prognosis and therapy and are now available for a comparative study with other ancient medical systems. However, in the framework of Assyriological studies there are still methodological problems that need to be addressed. Disregarding a retrospective diagnostic approach, this paper aims at highlighting the cultural–historical relevance of the medical information reported in cuneiform texts, assuming data related to skin imperfections and ailments as a case study. After a brief overview of the sources from ancient Mediterranean and Near Eastern cultures that may be referred to the modern medical specialty of dermatology, the specificities of Mesopotamian medicine and dermatology will be presented. Two examples, dedicated to the reconstruction of the ancient Mesopotamian view on the skin and the body, will demonstrate how relevant sources may be fruitfully analysed in a cultural–historical context.

Abstract Recent years have witnessed significant progress of workflow systems in different business areas. However, in the medical domain, the workflow systems are comparatively scarcely researched. In the medical domain, the workflows are as important as in other areas. In fact, the flow of information in the healthcare industry is even more critical than it is in other industries. Workflow can provide a new way of looking at how processes and procedures are completed in particular medical systems, and it can help improve the decision-making in these systems. Despite potential capabilities of workflow systems, medical systems still often perceive critical challenges in maintaining patient medical information that results in the difficulties in accessing patient data by different systems. In this paper, a new cloud-based service-oriented architecture is proposed. This architecture will support a medical workflow system integrated with cloud services aligned with medical standards to improve the healthcare system.
