Machine-to-machine (M2M) communication devices communicate and exchange information with each other in an independent manner to perform necessary tasks. The machine communicates with another machine over a wireless network. Wireless communication opens up the environment to huge vulnerabilities, making it very easy for hackers to gain access to sensitive information and carry out malicious actions. This paper proposes an M2M communication system through the internet in Tele-Robotics and provides network performance security. Tele-robotic systems are designed for surgery, treatment and diagnostics to be conducted across short or long distances while utilizing wireless communication networks. The systems also provide a low delay and secure communication system for the tele-robotics community and data security. The system can perform tasks autonomously and intelligently, minimizing the burden on medical staff and improving the quality and system performance of patient care. In the medical field, surgeons and patients are located at different places and connected through public networks. So the design of a medical sensor node network with LEACH protocol for secure and reliable communication ensures through the attack and without attack performance. Finally, the simulation results show low delay and reliable secure network transmission.

Although doctors are increasingly interested in electronic systems of registering medical record, but in practice such systems are used less. Mobile devices provide a new way for accessing users to data of health cares and services in a secure environment and user-selection. Mobile health cares' systems (M-health) are considered as a solution to reduce health care costs without reducing the quality of patient care. In this paper we are going to develop a common architecture for mobile health cares' services using NFC in order to facilitate providing health cares to people anywhere and anytime using the mobile devices that are connected to wireless communication technology, to be able to provide required services by a secure and available structure for patient' information in hospitals and health centers and treatment, especially intensive care units, emergency or patients needed home care. Also it can be avoided from forgery and misuse of physicians' stamp in current versions with this system by preparing electronic version using NFC technology.

AbstractIntroductionElectronic medical records (EMRs) are considered superior in documentation of care for medical practice. Current disaster medical response involves paper tracking systems and radio communication for mass-casualty incidents (MCIs). These systems are prone to errors, may be compromised by local conditions, and are labor intensive. Communication infrastructure may be impacted, overwhelmed by call volume, or destroyed by the disaster, making self-contained and secure EMR response a critical capability.ReportAs the prehospital disaster EMR allows for more robust content including protected health information (PHI), security measures must be instituted to safeguard these data. The Wireless Internet Information System for medicAl Response in Disasters (WIISARD) Research Group developed a handheld, linked, wireless EMR system utilizing current technology platforms. Smart phones connected to radio frequency identification (RFID) readers may be utilized to efficiently track casualties resulting from the incident. Medical information may be transmitted on an encrypted network to fellow prehospital team members, medical dispatch, and receiving medical centers. This system has been field tested in a number of exercises with excellent results, and future iterations will incorporate robust security measures.ConclusionA secure prehospital triage EMR improves documentation quality during disaster drills.DeMersG, KahnC, JohanssonP, BuonoC, ChiparaO, GriswoldW, ChanT.

Connected health is the convergence of medical devices, security devices, and communication technologies. It enables patients to be monitored and treated remotely from their home or primary care facility rather than attend outpatient clinics or be admitted to hospital. Patients’ data and medical records within a connected health system should be securely transmitted and saved for further analysis and diagnosis. This paper presents a reconfigurable wireless system for electrocardiogram (ECG) monitoring which can be deployed in a connected health environment. Efficient field programmable gate array (FPGA) implementation for the ECG encryption block has been carried out on the RC10 prototyping board using the advanced encryption standard (AES) algorithm. Results presented have shown that the proposed AES implementation outperforms the existing FPGA-based systems in different key performance metrics and that ECG signals acquired using the VitalSens device can be encrypted/decrypted in real-time. A software based evaluation approach has been also performed to validate the proposed hardware implementation. The proposed solution can be deployed for electronic archiving of health records information systems and health monitoring technologies in personalized medicine.

As the aging population of society continues to intensify, the series of problems brought about by aging is becoming more and more serious. Because the health problem of the elderly brings many social problems, people have paid close attention to it. Fortunately, as a typical smart healthcare system, wireless body area networks (WBANs) present quit nice medical care for people, especially the aged. However, personal health information is very sensitive. But, the common communication channel is used in WBANs and any malicious entity can initiate a security attack on WBANs. To ensure secure communication and privacy-preserving which are the premise of the sound development of WBANs, an improved and efficient certificateless authentication scheme with conditional privacy-preserving is proposed in this paper on the basis of analyzing the most recent presented certificateless authentication scheme for WBANs. The proposed scheme also provides batch authentication to decrease authentication and communication cost. A rigid security proof demonstrates that our proposed scheme resists every type of security attack and can provide condition privacy-preserving. The performance analysis shows that our proposed scheme has some advantages in computation and communication cost.

Full textAbstract:
With the massive deployment and application of intelligent systems such as smart life, smart medical care, and smart transportation, it is becoming more common for heterogeneous wireless networks such as WiFi, Zigbee, and Bluetooth to coexist in the same physical space. To improve the communication efficiency under the coexistence of heterogeneous wireless networks, this paper proposes an asynchronous data transmission method based on CTC technology, which constantly monitors the sleep and wake-up cycles of heterogeneous devices, makes full use of the wake-up cycle of the receiving terminal, and uses asynchronous methods to achieve cross-technology transmission of data packets. We also give a specific implementation scheme and use the program to simulate the transmission effect. The results show that our proposed method effectively reduces data transmission time and balances channel transmission throughput.

Full textAbstract:
In recent years, interval-valued Pythagorean fuzzy number is playing a more and more important role in decision management. It is a more effective and powerful tool to handle fuzzy information in decision problems. The multicriteria decision-making theory has been widely used in solving practical problems, such as the risk assessment of financial investment, engineering and construction, medical and health care, and information security. The main purpose of this paper is to apply a new interval-valued Pythagorean fuzzy decision-making method to practice and to analyze and solve the problem of wireless communication infrastructure. In this paper, a new interval-valued Pythagorean fuzzy ranking method, extending scope of application of the VIKOR method to interval-valued Pythagorean fuzzy set, is proposed. In order to adapt to actual needs, subjective and objective weights are combined to solve decision-making problems to enhance its practicality, validity, and effectiveness. An example of wireless communication infrastructure problem is provided to illustrate the rationality of this method and verify its advantages.

The wireless body area network (WBAN) which consists of wearable or implantable sensor nodes, is a technology that enables pervasive observing and delivery of health related information and services. The radio-enabled implantable medical devices offer a revolutionary set of applications among which we can point to precision drug distribution, smart endoscope capsules, glucose level observers and eye pressure detecting systems. Devices with WBAN are generally battery powered due to sensitivity and criticality of the data carried and handled by WBAN, reliability becomes a critical issues. WBAN loads a high degree of reliability as it openly affects the quality of patient observing. Undetected life-threatening circumstances can lead to death. A main requirement is that the health care professionals receive the monitored data correctly in emergency situations. The major objective is to achieve a reliable network with minimum delay and maximum throughput while considering power consumption by reducing unnecessary communication.

Full textAbstract:
Abstract:Health-care professionals have a broad range of needs for information and cooperation while working at different points of care (e.g., outpatient departments, wards, and functional units such as operating theaters). Patient-related data and medical knowledge have to be widely available to support high-quality patient care. Furthermore, due to the increased specialization of health-care professionals, efficient collaboration is required. Personal mobile information tools have a considerable potential to realize almost ubiquitous information and collaborative support. They enable to unite the functionality of conventional tools such as paper forms, dictating machines, and pagers into one tool. Moreover, they can extend the support already provided by clinical workstations. An approach is described for the integration of mobile information tools with heterogeneous hospital information systems. This approach includes identification of functions which should be provided on mobile tools. Major functions are the presentation of medical records and reports, electronic mailing to support interpersonal communication, and the provision of editors for structured clinical documentation. To realize those functions on mobile tools, we propose a document-based client-server architecture that enables mobile information tools to interoperate with existing computer-based application systems. Open application systems and powerful, partially wireless, hospital-wide networks are the prerequisites for the introduction of mobile information tools.

Full textAbstract:
Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2016.Zimbabwe has a fairly developed health-care delivery system that is served by public and private hospitals at district, provincial and national level. The public health-care system is the largest provider of health-care services and caters for the majority of the population but this is done in a resource-restricted context, typical of a developing context. In this context, this research sought to establish the potential of mHealth Technologies in Zimbabwe’s maternal health sector using Parirenyatwa and Harare hospitals as case studies. The reviewed body of knowledge, which was largely a comparative assessment of mHealth technology adoption in developing countries, indicated that the full adoption of the prevailing eHealth strategy in Zimbabwe remains hamstrung by the slow pace of policy implementation. This is a qualitative study and data was collected with unstructured interviews. Purposive and snowball sampling were used to recruit the participants. The gathered data was analyzed through content and thematic analysis. Four broad themes emerged from the primary data collected during the interviews and these include: trends in information dissemination in Zimbabwe’s Public Health System; information needs for expectant women and midwives; the prevalence of ICT use in Zimbabwe’s Public Health System, and mobile technology use in the maternal health sector in Zimbabwe. The research was able to establish that while there is a high proliferation of smartphone use among most expectant women, this has not translated into their use for health information-related purposes.

Thesis (DPhil (Informatics))--Cape Peninsula University of Technology, 2018.As in many parts of the world, the need for healthcare services is increasing rapidly in South Africa. Owing to many official languages in the country, health service delivery is continuously challenged by spoken language and semantics. The challenges result to poor health services in many areas of the country. Thus, this study was undertaken with the aim: to develop a framework which can be used to guide the selection and implementation of mobile systems in the translation of language semantics for improved healthcare service delivery in South Africa. For this purpose, the study was based on one significant research question: How can the challenge(s) of semantics and language translation in South African healthcare delivery be addressed using mobile systems? In achieving the aim of the study, a qualitative study was conducted using the semi-strtructured interviews to collect the data. The analysis of the data was carried out using the hermeneutic approach within the interpretative paradigm, which was guided by two theories, actor network theory (ANT) and diffusion of innovation (DOI). The ANT was used to focus on the interaction and relationship between human and non-human actors within a heterogeneous networks, in the activities of healthcare. The DOI was employed to examine how mobiles systems can be diffused, in addressing the challenges and barriers which the health facilities encounter from language perspective. The case study approach was followed, based on three cases, two healthcare organisations, and a community in the northern part of South Africa were used in the study. Based on the analysis of the data, the influencing factors were found, and interpreted. The interpretation helps gain deeper understanding of the challenges, from which a framework (see Figure 6.5 in Chapter 6) was developed. From an understanding of the factors that influence language semantics, and its translaton by using mobile systems, challenges in the South African healthcare can be reduced, and quality improved. The way in which the theories were used brought a fresh perspective to the study. In practice, the framework can be used by both healthcare practitioners and ICT specialists to guide the selection, use and support of mobile systems for the translation of language semantics in South Africa. The complementary use of ANT and DOI in the study contributes methodologically.

Full textAbstract:
The public healthcare sectors within developing nations face a lot of challenges because of constrained resources available to them. The South African public healthcare sector is no different. Although it serves the majority of the South African population, most of the financial resources are directed towards the private sector, which serves very few individuals when compared to the public healthcare sector. Apart from that, other challenges that the National Department of Health has to deal with include the lack of sufficiently trained healthcare employees who can work on the different levels of the public healthcare sector, as well as the burden of diseases such as HIV and Aids, tuberculosis and other chronic diseases. In order to improve service delivery, the National Department of Health is introducing Information and Communications Technology interventions that can increase efficiency and reduce costs, thereby improving the quality of service delivery. This research delivers an m-health application user experience framework to be proposed to the National Department of Health in South Africa, in order to assist in scaling up of m-health applications. The m-health applications that can benefit the South African population if scaled up successfully include those that can be used in remote data collection, treatment and compliance, accessing patients records, remote monitoring, communication and training for healthcare workers and applications that can be used for education and awareness. The study focused on three domains: the Human-Computer Interaction domain, public healthcare domain and Health Informatics domain. The proposed framework was realized by investigating mobile user experience components, mobile health requirements and the South African public healthcare domain components that contribute to the m-health user experience framework. This research was conducted through the interpretivist philosophy. Due to the exploratory nature of the study, an application of qualitative methodology was used. The conceptual theoretical framework was validated through a single case study approach by m-health user experience experts, who reside in South Africa. Data were analysed inductively. An m-health user experience framework was provided at the end of the study. An m-health user experience framework can assist the National Department of Health to look into design issues, address m-health requirements and put the domain needs in place, thus enabling the Department to successfully scale up implementations of m-health applications nationwide.

Dans cette thèse, nous avons proposé des solutions originales et performantes pour l’économie d’énergie dans les réseaux de capteurs sans fil (RCSF). Ces contributions s'organisent autour de deux grands axes : les réseaux de capteurs génériques et les réseaux de capteurs sans fil dédiés aux applications santé. Dans un premier temps, nous avons réalisé un état-de-l’art des mécanismes d'économie d’énergie pour les RCSF. Nous avons ensuite proposé deux solutions originales : la première optimise le déplacement d’une station de base, ainsi que la façon dont les données sont stockées dans les capteurs et routées vers le puit mobile ; la seconde optimise le déploiement de chargeurs mobiles, qui une fois dans le réseau permettent de satisfaire la demande en énergie des nœuds via la transmission d’énergie sans fil sur plusieurs sauts. Dans un second temps, nous nous sommes intéressés plus particulièrement aux applications des RCSF pour la supervision de patients à distance. Nous avons introduit une nouvelle classification des techniques économes en énergie adaptées à la spécificité de ces applications santé. Nous avons ensuite proposé une nouvelle architecture pour la supervision de patient à distance à l’aide de capteurs sans fil qui permet de prolonger la durée de vie des capteurs et de la station de base. Cette solution prend en compte l’environnement du patient et l’hétérogénéité des appareils. Nos résultats montrent que la durée de vie des réseaux de capteurs sans fil peut être étendue en utilisant les différentes stratégies proposées. L’efficacité de ces approches a été confirmée à l’aide de nombreuses expérimentations numériques et simulationsIn this thesis, we propose new strategies for energy conservation in wireless sensor networks, so that the operational time of these networks can be extended. The work can be divided into two main focus area, namely general wireless sensor networks, and healthcareoriented wearable sensor networks. In the first part of this thesis we provide a comprehensive survey of the existing energy-efficient mechanisms. Then, we propose two new solutions: the first one optimizes the displacement of a mobile base station as well as buffer usage and data routing at sensor nodes; the second one optimizes the deployment of wireless chargers in the network to satisfy the energy demand of the sensors. The second part of this thesis is dedicated to healthcare application where wearable sensors are used to remotely supervise a patient. We begin with a state-of-the-art of the energy-efficient techniques existing in the literature. We then introduce a new energy-efficient architecture that allows to optimize the lifetime of both the sensor and the base station. This is a context-aware solution that takes into consideration heterogeneous devices. Our results show that the lifetime of the sensor networks can be extended using the proposed strategies. All the results obtained are supported by numerical experiments and extensive simulations

Human body is a complex system organized at different levels such as cells, tissues and organs, which contributes to 11 important organ systems. The functional efficiency of this complex system is evaluated as health. Traditional healthcare is unable to accommodate everyone's need due to the ever-increasing population and medical costs. With advancements in technology and medical research, traditional healthcare applications are shaping into smart healthcare solutions. Smart healthcare helps in continuously monitoring our body parameters, which helps in keeping people health-aware. It provides the ability for remote assistance, which helps in utilizing the available resources to maximum potential. The backbone of smart healthcare solutions is Internet of Things (IoT) which increases the computing capacity of the real-world components by using cloud-based solutions. The basic elements of these IoT based smart healthcare solutions are called "things." Things are simple sensors or actuators, which have the capacity to wirelessly connect with each other and to the internet. The research for this dissertation aims in developing architectures for these things, focusing on IoT-based smart healthcare solutions. The core for this dissertation is to contribute to the research in smart healthcare by identifying applications which can be monitored remotely. For this, application-specific thing architectures were proposed based on monitoring a specific body parameter; monitoring physical health for family and friends; and optimizing the power budget of IoT body sensor network using human body communications. The experimental results show promising scope towards improving the quality of life, through needle-less and cost-effective smart healthcare solutions.

Three decades of mobile phone diffusion, thousands of mobile-phone-based health projects worldwide ("mHealth"), and tens of thousands of health applications in Apple's iTunes store, but fundamental questions about the effect of phone diffusion on people's healthcare behaviour remain unanswered. Empirical, theoretical, and methodological gaps in the study of mobile phones and health reinforce each other and lead to simplifying assumptions that mobile phones are a ubiquitous and neutral platform for interventions to improve health and healthcare. This contradicts what we know from the technology adoption literature. This thesis explores the theoretical link between mobile phone diffusion and healthcare access; develops and tests a new multidimensional indicator of mobile phone adoption; and analyses the effects of phone use on people's healthcare-seeking behaviour. My mixed methods research design - implemented in rural Rajasthan (India) and Gansu (China) - involves qualitative research with 231 participants and primary survey data from 800 persons. My research yields a qualitatively grounded framework that describes the accessibility and suitability of mobile phones in healthcare-seeking processes, the heterogeneous outcomes of phone use and non-use on healthcare access, and the uneven equity consequences in this process. Quantitative analysis based on the framework finds that mobile phone use in rural India and China increases access to healthcare, but it also invites more complex and delayed health behaviours and the over-use of scarce healthcare resources. Moreover, increasing phone-aided health action threatens to marginalise socio-economically disadvantaged groups further. I present here the first quantitative evidence on how mobile phone adoption influences healthcare-seeking behaviour. This challenges the common view that mHealth interventions operate on a neutral platform and draws attention to potential targeting, user acceptance, and sustainability problems. The framework and tools developed in this thesis can support policy considerations for health systems to evaluate and address the healthcare implications of mobile phone diffusion.

The advances in communication technologies have resulted in a significant shift in the workplace culture. Mobile computing devices are increasingly becoming an integral part of workplace culture. Mobility has several advantages to the organisation, one such example is the “always online” workforce resulting in increased productivity hours. As a result, organisations are increasingly providing mobile computing devices to the workforce to enable remote productivity at the organisations cost. A challenge associated with mobility is that these devices are likely to connect to a variety of networks, some which may insecure, and because of their smaller form factor and perceived value, are vulnerable to loss and theft amongst other information security challenges. Increased mobility has far reaching benefits for remote and rural communities, particularly in the healthcare domain where health workers are able to provide services to previously inaccessible populations. The adverse economic and infrastructure environment means institution provided devices make up the bulk of the mobile computing devices, and taking away the ownership, the usage patterns and the susceptibility of information to adversity are similar. It is for this reason that this study focuses on information security on institution provided devices in a rural healthcare setting. This study falls into the design science paradigm and is guided by the principles of design science proposed by Hevner et al. The research process incorporates literature reviews focusing on health information systems security and identifying theoretical constructs that support the low-resource based secure deployment of health information technologies. Thereafter, the artifact is developed and evaluated through an implementation case study and expert reviews. The outcomes from the feedback are integrated into the framework.

Full textAbstract:
In developing countries, acute respiratory infections (ARIs) are responsible for two million deaths per year. Most victims are children who are less than 5 years old. Pneumonia kills 5000 children per day. The statistics for cardiovascular diseases (CVDs) are even more alarming. According to a 2009 report from the World Health Organization (WHO), CVDs kill 17 million people per year. In many resource-poor parts of the world such as India and China, many people are unable to access cardiologists, pulmonologists, and other specialists. Hence, low skilled health professionals are responsible for screening people for ARIs and CVDs in these areas. For example, in the rural areas of the Philippines, there is only one doctor for every 10,000 people. By contrast, the United States has one doctor for every 500 Americans. Due to advances in technology, it is now possible to use a smartphone for audio recording, signal processing, and machine learning. In my thesis, I have developed an Android application named Smart Auscultation. Auscultation is a process in which physicians listen to heart and lung sounds to diagnose disorders. Cardiologists spend years mastering this skill. The Smart Auscultation application is capable of recording and classifying heart sounds, and can be used by public or clinical health workers. This application can detect abnormal heart sounds with up to 92-98% accuracy. In addition, the application can record, but not yet classify, lung sounds. This application will be able to help save thousands of lives by allowing anyone to identify abnormal heart and lung sounds.

Full textAbstract:
Modern implantable and body worn medical devices leverage wireless telemetry to improve patient experience and expand therapeutic options. Wireless medical devices are subject to a unique set of regulations in which monitoring of the available frequency spectrum is a requirement. To this end, implants use software protocols to assess the in-band activity to determine which channel should be used. These software protocols take valuable processing time and possibly degrade the operational lifetime of the battery. Implantable medical devices often take advantage of a single chip transceiver as the physical layer for wireless communications. Embedding the channel assessment task in the transceiver hardware would free the limited resources of the microprocessor. This thesis proposes hardware modifications to existing transceiver architectures which would provide an automated channel assessment means for implantable medical devices. The results are applicable beyond medical device applications and could be employed to benefit any low-power, wireless, battery-operated equipment.

Full textAbstract:
With the current advancement in micro-and nano-fabrication processes and the newly developed approaches, wireless implantable devices are now able to meet the demand for compact, self-powered, wireless, and long-lasting implantable devices for medical and health-care applications. The demonstrated fabrication advancement enabled the wireless implantable devices to overcome the previous limitations of electromagnetic-based wireless devices such as the high volume due to large antenna size and to overcome the tissue and bone losses related to the ultrasound implantable devices. Recent state-of-the-are wireless implantable devices can efficiently harvest electromagnetic energy and detect RF signals with minimum losses. Most of the current implanted devices are powered by batteries, which is not an ideal solution as these batteries need periodic charging and replacement. On the other hand, the implantable devices that are powered by energy harvesters are operating continuously, patient-friendly, and are easy to use. Future wireless implantable devices face a strong demand to be linked with IoT-based applications and devices with data visualization on mobile devices. This type of application requires additional units, which means more power consumption. Thus, the challenge here is to reduce the overall power consumption and increase the wireless power transfer efficiency. This chapter presents the state-of-the-art wireless power transfer techniques and approaches that are used to drive implantable devices. These techniques include inductive coupling, radiofrequency, ultrasonic, photovoltaic, and heat. The advantages and disadvantages of these approaches and techniques along with the challenges and limitations of each technique will be discussed. Furthermore, the performance parameters such as operating distance, energy harvesting efficiency, and size will be discussed and analyzed to introduce a comprehensive comparison. Finally, the recent advances in materials development and wireless communication strategies, are also discussed.

The wireless body area network (WBAN) which consists of wearable or implantable sensor nodes, is a technology that enables pervasive observing and delivery of health related information and services. The radio-enabled implantable medical devices offer a revolutionary set of applications among which we can point to precision drug distribution, smart endoscope capsules, glucose level observers and eye pressure detecting systems. Devices with WBAN are generally battery powered due to sensitivity and criticality of the data carried and handled by WBAN, reliability becomes a critical issues. WBAN loads a high degree of reliability as it openly affects the quality of patient observing. Undetected life-threatening circumstances can lead to death. A main requirement is that the health care professionals receive the monitored data correctly in emergency situations.

Full textAbstract:
The widespread and fast-developing information technologies, especially wireless communications and the Internet, have allowed for the realization of greater automation systems than ever in health-care industries: E-health has become an apparent trend, and having a clinic at home or even anywhere at anytime is no longer a dream. E-health, including telemedicine featured by conducting health-care transactions over the Internet, has been revolutionizing the well-being of human society. Traditionally, common practices in the health-care industry place tremendous burdens on both patients and health-care providers, with heavy loads of paper-based documents and inefficient communications through mail or phone calls. The transmission of medical data is even messy for cases in which patients have to transfer between different health providers. In addition, the medical documents prepared manually are prone to errors and delays, which may lead to serious consequences. The time, energy, and resources wasted in such processes are intolerable and unimaginable in any fast-paced society. For these problems, e-health provides powerful solutions to share and exchange information over the Internet in a timely, easy, and safe manner (Balas et al., 1997). Incorporating fast and cost-efficient Internet and wireless communication techniques has enabled the substantial development of e-health. The use of the Internet to transmit sensitive medical data, however, leaves the door open to the threats of information misuse either accidentally or maliciously. Health-care industries need be extremely cautious in handling and delivering electronic patient records using computer networks due to the high vulnerabilities of such information. To this extent, security and privacy issues become two of the biggest concerns in developing e-health infrastructures.

Full textAbstract:
The advancement in the field of information and communication technology has generated a great deal of information that was not possible to access earlier. Healthcare systems are one of the most beneficial applications using wireless medical sensor technologies, which can facilitate patient care within homes, hospitals, clinics, disaster sites, and the open environment. The integration and sharing of such information can contribute significantly to a better understanding of patients' health conditions and therefore to improving the quality of healthcare provided to them. However, in order to achieve sufficient levels of collaborative use of information among healthcare-related practitioners, there is a need to overcome a number of issues such as privacy and interoperability, among others. This chapter discusses two of the main challenges encountered before healthcare information systems can collaboratively share patients' records, namely privacy and interoperability.
