Reporting an Experience on Design and Implementation of e-Health Systems on Azure Cloud
Electronic Health (e-Health) technology has brought the world with
significant transformation from traditional paper-based medical practice to
Information and Communication Technologies (ICT)-based systems for automatic
management (storage, processing, and archiving) of information. Traditionally
e-Health systems have been designed to operate within stovepipes on dedicated
networks, physical computers, and locally managed software platforms that make
it susceptible to many serious limitations including: 1) lack of on-demand
scalability during critical situations; 2) high administrative overheads and
costs; and 3) in-efficient resource utilization and energy consumption due to
lack of automation. In this paper, we present an approach to migrate the ICT
systems in the e-Health sector from traditional in-house Client/Server (C/S)
architecture to the virtualised cloud computing environment. To this end, we
developed two cloud-based e-Health applications (Medical Practice Management
System and Telemedicine Practice System) for demonstrating how cloud services
can be leveraged for developing and deploying such applications. The Windows
Azure cloud computing platform is selected as an example public cloud platform
for our study. We conducted several performance evaluation experiments to
understand the Quality Service (QoS) tradeoffs of our applications under
variable workload on Azure.Comment: Submitted to third IEEE International Conference on Cloud and Green

Advancing Healthcare Security: A Cutting-Edge Zero-Trust Blockchain Solution for Protecting Electronic Health Records
The effective management of electronic health records (EHRs) is vital in healthcare. However, traditional systems often need help handling data inconsistently, providing limited access, and coordinating poorly across facilities. This study aims to tackle these issues using blockchain technology to improve EHR systems' data security, privacy, and interoperability. By thoroughly analyzing blockchain's applications in healthcare, we propose an innovative solution that leverages blockchain's decentralized and immutable nature, combined with advanced encryption techniques such as the Advanced Encryption Standard and Zero Knowledge Proof Protocol, to fortify EHR systems. Our research demonstrates that blockchain can effectively overcome significant EHR challenges, including fragmented data and interoperability problems, by facilitating secure and transparent data exchange, leading to enhanced coordination, care quality, and cost-efficiency across healthcare facilities. This study offers practical guidelines for implementing blockchain technology in healthcare, emphasizing a balanced approach to interoperability, privacy, and security. It represents a significant advancement over traditional EHR systems, boosting security and affording patients greater control over their health records. Doi: 10.28991/HIJ-2023-04-03-012 Full Text: PD
Integrated, reliable and cloud-based personal health record: a scoping review.
Personal Health Records (PHR) emerge as an alternative to integrate patient’s health information to give a global view of patients' status. However, integration is not a trivial feature when dealing with a variety electronic health systems from healthcare centers. Access to PHR sensitive information must comply with privacy policies defined by the patient. Architecture PHR design should be in accordance to these, and take advantage of nowadays technology. Cloud computing is a current technology that provides scalability, ubiquity, and elasticity features. This paper presents a scoping review related to PHR systems that achieve three characteristics: integrated, reliable and cloud-based. We found 101 articles that addressed thosecharacteristics. We identified four main research topics: proposal/developed systems, PHR recommendations for development, system integration and standards, and security and privacy. Integration is tackled with HL7 CDA standard. Information reliability is based in ABE security-privacy mechanism. Cloud-based technology access is achieved via SOA.CONACYT - Consejo Nacional de Ciencia y TecnologĂaPROCIENCI
A Scalable Multi-Layered Blockchain Architecture for Enhanced EHR Sharing and Drug Supply Chain Management
In recent years, the healthcare sector's shift to online platforms has
spotlighted challenges concerning data security, privacy, and scalability.
Blockchain technology, known for its decentralized, secure, and immutable
nature, emerges as a viable solution for these pressing issues. This article
presents an innovative Electronic Health Records (EHR) sharing and drug supply
chain management framework tailored to address scalability, security, data
integrity, traceability, and secure data sharing. The framework introduces five
layers and transactions, prioritizing patient-centric healthcare by granting
patients comprehensive access control over their health information. This
access facilitates smoother processes, such as insurance claims, while
maintaining robust security measures. Notably, our implementation of
parallelism significantly bolsters scalability and transaction throughput while
minimizing network traffic. Performance evaluations conducted through the
Caliper benchmark indicate a slight increase in processor consumption during
specific transactions, mitigated effectively by parallelization. RAM
requirements remain largely stable. Additionally, our approach notably reduces
network traffic while tripling transaction throughput. The framework ensures
patient privacy, data integrity, access control, and interoperability, aligning
with traditional healthcare systems. Moreover, it provides transparency and
real-time drug supply monitoring, empowering decision-makers with actionable
insights. As healthcare evolves, our framework sets a crucial precedent for
innovative, scalable, and secure systems. Future enhancements could focus on
scalability, real-world deployment, standardized data formats, reinforced
security protocols, privacy preservation, and IoT integration to comply with
regulations and meet evolving industry needs
The Evolution of Access Control in Cloud Security: A Survey of Key Literature
Cloud Computing is a distributed model that enables users to access, meet and exchange resources and resource requirements hosted by various service providers. Authentication of requesting users and the permitting of their rights of access are extremely necessary in order to avoid unauthorised or unlawful access to cloud services. In the cloud scenario, access control of distributed resources is most critical. Access control is a basic aspect of the security of information that is directly linked to the fundamental features of confidentiality, honesty and availability. This article provides a literature analysis of the Cloud Computing Access Control Mechanism
