“…Most of the research reviewed focused on blockchain’s use to strengthen HIT security or patients’ privacy during health data exchange or access; 53% (37/70) papers focused on addressing patients’ lack of control over the privacy and security of their data [ 10 - 46 ], and 40% (28/70) papers addressed blockchain’s ability to prevent data tampering [ 10 , 12 , 21 , 25 , 33 , 34 , 37 , 38 , 40 - 44 , 46 - 60 ]. Data breaches were addressed in 37% (26/70) papers [ 15 , 18 , 19 , 22 , 24 , 29 , 31 , 32 , 34 , 36 - 38 , 43 , 44 , 54 , 56 - 66 ], 9% (6/70) papers mentioned malicious attacks (eg, impersonation) that blockchain could potentially resolve [ 17 , 34 , 44 , 56 , 60 , 67 ], and 4% (3/70) papers focused on how blockchain can preserve patients’ anonymity while third parties accessed their health and medical records for activities such as medical research [ 41 , 42 , 68 ].…”

“…The EMR differs from the EHR as it focuses on the internal medical domain of health organizations and is not integrated between health care providers. Blockchain’s use for EHRs, EMRs, and other record systems in which records are originated and controlled by providers was discussed in 51% (36/70) papers [ 11 , 14 - 21 , 27 , 29 , 30 , 33 , 35 - 37 , 40 , 42 - 44 , 46 , 49 , 53 , 55 , 59 , 60 , 63 , 67 , 68 , 72 - 74 , 76 - 78 , 84 ]. Using blockchain to integrate various health record systems (EHR, EMR, PHR, etc), mHealth, and telemedicine platforms can contribute to patient empowerment and patient engagement by providing a synchronized view of patient information to patients and health care providers, to support patient decision making and control.…”

Background Blockchain offers a promising new distributed technology to address the challenges of data standardization, system interoperability, security, privacy, and accessibility of medical records. Objective The purpose of this review is to assess the research on the use of blockchain technology for patient care and the associated challenges and to provide a research agenda for future research. Methods This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. We queried the Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, Excerpta Medica dataBASE (EMBASE), and Web of Science databases for peer-reviewed research articles published up to December 2019 that examined the implementation of blockchain technology in health care settings. We identified 800 articles from which we selected 70 empirical research articles for a detailed review. Results Blockchain-based patient care applications include medical information systems, personal health records, mobile health and telemedicine, data preservation systems and social networks, health information exchanges and remote monitoring systems, and medical research systems. These blockchain-based health care applications may improve patient engagement and empowerment, improve health care provider access to information, and enhance the use of health care information for medical research. Conclusions Blockchain health information technology (HIT) provides benefits such as ensuring data privacy and security of health data, facilitating interoperability of heterogeneous HIT systems, and improving the quality of health care outcomes. However, barriers to using blockchain technology to build HIT include security and privacy vulnerabilities, user resistance, high computing power requirements and implementation costs, inefficient consensus algorithms, and challenges of integrating blockchain with existing HIT. With 51% of the research focused on medical information systems such as electronic health record and electronic medical record, and 53% of the research focused on data security and privacy issues, this review shows that HIT research is primarily focused on the use of blockchain technologies to address the current challenges HIT faces. Although Blockchain presents significant potential for disrupting health care, most ideas are in their infancy.

“…After all the findings for cloud-based e-health system security we would like to recommend to consider the papers ( [68], [78], [81], [82], [85]) on blockchain-based mechanism as it is more trending in recent days, the papers ( [74], [75], [76], [80]) on biometric-based mechanism for mobile devices. If anyone considering cryptographic methods for securing cloud-based e-health system then they should consider the papers ( [27], [30], [31], [42], [43], [63], [64] for AES based), ( [43], [64], [69] for RSA based) and ( [38], [42], [51], [53], [63], [65] for ABE based) hybrid system.…”

“…personally controlled E-HR system using blockchain technology where blockchain can be used for verifying the ownership of the patient's data, giving access permissions and ensuring the data integrity. In [81], to satisfy the criteria of distribution architecture a protocol named pseudonymbased encryption and different authorities (PBEDA) was proposed along with multi-tier blockchain technology in an e-health system. In [82], blockchain is used to protect the outsourced E-HRs from the illegal alteration as every operation on the outsourcing E-HRs is summed up to a transaction.…”

INTRODUCTION: The e-health (electronic health) system is one of many cloud services which uses computer or electronic systems and cloud technology as its main source of operations for storing and sharing patient's medical data between healthcare service providers and patients. The health data records are kept in a semi-trusted third-party supplier (i.e., cloud). Therefore, its security has become the main concern as the data should not be accessible to unauthorized person. OBJECTIVES: To provide a brief knowledge on the security aspects of cloud-based e-health systems for further improvement in the field of e-health system security. METHODS: This paper presents a literature survey on secure cloud-based e-health systems including ninety-four research papers related to secure cloud-based e-health systems collected from different sources till 2019. RESULTS: The security mechanisms used to secure cloud-based e-health systems are divided into three categories (i.e., crypto, non-crypto, and biometric-based). Also some health related security laws, security mechanisms, advantages and limitations of security mechanisms for all categories are presented. CONCLUSION: This paper will be helpful to do further researches in the research area of e-health system as it consists of the analysis of security mechanisms, security laws, advantages and limitations of the security mechanisms.

“…Since an indisputable property of the blockchain is promoting efficient, secure and verifiable information management [17,47,48], which, by default, facilitates auditability [49,50], it has tremendous potential in healthcare, particularly for cross-organizational environments. The literature refers to several applications of blockchain technology in healthcare, namely in guaranteeing electronic health record integrity [51][52][53][54][55][56][57], facilitating clinical information sharing [20,[58][59][60][61][62], protecting information acquired by remote monitoring systems [20,[63][64][65], and solving problems with both a finding's scientific credibility (e.g., missing data, endpoint switching or data dredging) in clinical trials [66] and with a patient's informed consent [17,67,68].…”

Current epidemiological changes promote a trend toward distributed care provision in the community. Digital platforms allowing the exchange of patient information are essential in optimizing community care. However, these digital platforms should present trustworthy environments. This article reports a study aiming to implement and evaluate a Logging Service based on blockchain technologies to guarantee the integrity of the activity logs of the Social Cooperation for Integrated Assisted Living platform. This platform of services was developed to support integrated care and assistance of communitydwelling older adults and uses the Fast Healthcare Interoperability Resources to promote information interoperability.
