Blockchain with cloud for handling healthcare data: A privacy-friendly platform
In addition to its unique characteristics, health care data make it an attractive target for criminals. Additionally, healthcare data is highly regulated by US & EU privacy and security laws and international laws governing data storage in the cloud. The value of healthcare data and these regulatory requirements have motivated organizations to use blockchain to protect data. Blockchain will facilitate effective data exchange while maintaining patient privacy and data protection. Cloud data has long been a draw for cyber attackers. Today, cloud health data has been their latest interest. The cloud-based application that theoretically transforms the operation and communication of existing healthcare networks is EHR. The EHR is a digital file comprising the personal details of citizens/patients (name, photo, address, age, etc.) and health (existing diseases, previous surgeries, allergies, blood type, allergies, vaccinations, etc.). Maximizing cost efficiency is one of the drivers for integrating cloud services in health care. The return on investment for healthcare services is better when using cloud solutions. The cloud infrastructure includes a centralized medical record entry point, allowing many clinicians to display laboratory reports or consult patient notes. Loud technologies would allow researchers to explore these data and analyses public health more accurately. Cloud technology is not the best way to handle the medical services and records of the healthcare system. Nevertheless, this technology allows patients and physicians access to software that will enhance patient care. The Cloud also provides an excellent opportunity to utilize patient data on a health computer scale to draw insights on health and allow patients to manage personal details quickly and efficiently. There are hurdles in introducing emerging technologies and threatening privacy violations, but health services will utilize this increasingly growing and valuable technology with the appropriate training and framework. As part of this paper, we present a patient-centric healthcare data management solution that uses blockchain technology as a storage mechanism that helps to ensure patient privacy.

Paper, 2022
In terms of data transparency, provenance, authenticity, verification, data provenance, propositions, reliability, transparency, and safety, today's healthcare data management systems face significant hurdles. Blockchain refers to a decentralized network of computer nodes that may survive together without needing to rely on one another and preserve identical data. The use of blockchain technologies for the provision of safe and confidential healthcare managing data had also attracted considerable interest. In terms of accurate diagnosis and care through safe and secure intelligence sharing, blockchain is also converting traditional care methods into more dependable methods. Blockchain technology has the potential to contribute to personalized, authentic, and secure healthcare in the future by combining every actual relevant data to a particular patient and displaying it in a modern, safe healthcare environment. By using blockchain as a framework, we examine both the recent and current changes in the healthcare industry in this article. Together with problems and answers. This paper identifies challenges and opportunities for implementing blockchain technology in healthcare and summarizes health-related blockchain products and key players offering solutions across different applications. In doing this, our research extends and complements existing blockchain research in healthcare.

The need for patient-centered electronic records that can store and retrieve the myriad details of a patient's medical history as documented during treatment has increased dramatically. These records are vital for future care, billing, or treatment. The distributed ledger technology known as Blockchain enables us to store this data and start and enable use at lightning speed while keeping the system transparent and secure. Using a distributed system with ledger capability allows for the safe and interoperable storage of records. With the elimination of mediators in financial and data transactions and in verifying data authenticity and ownership records, blockchain technology promises to alter the current state of digital asset transactions radically. Its extensive files and easy access to patients' medical histories are two of the most critical issues in healthcare, and its immutability, decentralization, and openness make it an ideal solution. Interoperability, the ability of various health organizations and software product makers to connect and exchange data securely and smoothly, is crucial to healthcare systems' practical and successful operation. Lack of interoperability is the root cause of many difficulties in contemporary healthcare, including data silos and disparate workflow tools. To solve this problem, a system that allows safe, recognized medical records to be kept in separate databases should be implemented. Using fog computing, which can decentralize data processing and handle massive amounts of data, we reviewed the literature and performed a system overview of blockchain technology in this study. Our ongoing experimental study highlights areas where current systems are lacking and suggests potential avenues for further research.
BLOCKCHAIN HEALTHCARE: REDEFINING DATA OWNERSHIP AND TRUST IN THE MEDICAL ECOSYSTEM
IAEME PUBLICATION, 2020
As healthcare systems migrate towards digitized data management, the secure and privacy-preserving exchange of medical information becomes paramount. Traditional centralized infrastructures suffer from vulnerabilities, data breaches, and limited patient control, jeopardizing both security and autonomy. Enter blockchain technology, a distributed ledger infrastructure offering a paradigm shift in healthcare data sharing. This paper delves into the transformative potential of blockchain in securing sensitive medical data while empowering patients with control over their information. We explore how blockchain's immutable and tamper-proof nature fosters data integrity, minimizing the risk of unauthorized access and malicious alterations. Patients are further empowered through fine-grained access control mechanisms, allowing them to grant or revoke access to specific institutions and individuals, thereby promoting autonomy and privacy. The paper dives deeper into addressing privacy concerns inherent to blockchain's transparency. We detail strategies such as data encryption, zero-knowledge proofs, and permissioned blockchains, showcasing how patient information can remain confidential even within a distributed ledger system. We also recognize the challenges of scalability, regulation, and existing infrastructure integration, outlining potential solutions and future research directions. Ultimately, this paper argues that blockchain technology holds immense promise for revolutionizing healthcare data exchange. By enhancing security, promoting patient autonomy, and facilitating seamless data interoperability, blockchain paves the way for a future of personalized and efficient medical care. The road ahead requires addressing technical and regulatory hurdles, but the potential benefits for secure and patientcentric data management are undeniable. This paper serves as a roadmap for harnessing the power of blockchain to empower patients, safeguard their privacy, and ultimately transform healthcare for the better.
Future Internet
Electronic health records (EHRs) play an important role in our life. However, most of the time, they are scattered and saved on different databases belonging to distinct institutions (hospitals, laboratories, clinics, etc.) geographically distributed across one or many countries. Due to this decentralization and the heterogeneity of the different involved systems, medical staff are facing difficulties in correctly collaborating by sharing, protecting, and tracking their patient’s electronic health-record history to provide them with the best care. Additionally, patients have no control over their private EHRs. Blockchain has many promising future uses for the healthcare domain because it provides a better solution for sharing data while preserving the integrity, the interoperability, the availability of the classical client–server architectures used to manage EHRS. This paper proposes a framework called HealthBlock for collaboratively sharing EHRs and their privacy preservation. Dif...

Healthcare data are considered sensitive and confidential, and storing these sensitive data in traditional (i.e., centralized) databases may expose risks, such as penetration or data leaks. Furthermore, patients may have incomplete health records since they visit various healthcare centers and leave their data scattered in different places. One solution to resolve these problems and permit patients to own their records is a decentralized personal health record (PHR); this can be achieved through decentralization and distribution systems, which are fundamental attributes of blockchain technology. Additionally, the requirements for this solution should be identified to provide practical solutions for stakeholders. This study aims to identify the key requirements for PHRs. A design science methodology was utilized to meet the study objectives, and thirteen healthcare experts were interviewed to elicit the requirements and the previous studies. Thirty-three requirements are defined, and...
