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
Droplet: Decentralized Authorization for IoT Data Streams
This paper presents Droplet, a decentralized data access control service,
which operates without intermediate trust entities. Droplet enables data owners
to securely and selectively share their encrypted data while guaranteeing data
confidentiality against unauthorized parties. Droplet's contribution lies in
coupling two key ideas: (i) a new cryptographically-enforced access control
scheme for encrypted data streams that enables users to define fine-grained
stream-specific access policies, and (ii) a decentralized authorization service
that handles user-defined access policies. In this paper, we present Droplet's
design, the reference implementation of Droplet, and experimental results of
three case-study apps atop of Droplet: Fitbit activity tracker, Ava health
tracker, and ECOviz smart meter dashboard
Blockchain inspired secure and reliable data exchange architecture for cyber-physical healthcare system 4.0
A cyber-physical system is considered to be a collection of strongly coupled communication systems and devices that poses numerous security trials in various industrial applications including healthcare. The security and privacy of patient data is still a big concern because healthcare data is sensitive and valuable, and it is most targeted over the internet. Moreover, from the industrial perspective, the cyber-physical system plays a crucial role in the exchange of data remotely using sensor nodes in distributed environments. In the healthcare industry, Blockchain technology offers a promising solution to resolve most securities-related issues due to its decentralized, immutability, and transparency properties. In this paper, a blockchain-inspired secure and reliable data exchange architecture is proposed in the cyber-physical healthcare industry 4.0. The proposed system uses the BigchainDB, Tendermint, Inter-Planetary-File-System (IPFS), MongoDB, and AES encryption algorithms to improve Healthcare 4.0. Furthermore, blockchain-enabled secure healthcare architecture for accessing and managing the records between Doctors and Patients is introduced. The development of a blockchain-based Electronic Healthcare Record (EHR) exchange system is purely patient-centric, which means the entire control of data is in the owner's hand which is backed by blockchain for security and privacy. Our experimental results reveal that the proposed architecture is robust to handle more security attacks and can recover the data if 2/3 of nodes are failed. The proposed model is patient-centric, and control of data is in the patient's hand to enhance security and privacy, even system administrators can't access data without user permission
Using Blockchain to Achieve Decentralized Privacy In IoT Healthcare
With the advent of the Internet of Things (IoT), e-health has become one of
the main topics of research. Due to the sensitivity of patient information,
patient privacy seems challenging. Nowadays, patient data is usually stored in
the cloud in healthcare programs, making it difficult for users to have enough
control over their data. The recent increment in announced cases of security
and surveillance breaches compromising patients' privacy call into question the
conventional model, in which third-parties gather and control immense amounts
of patients' Healthcare data. In this work, we try to resolve the issues
mentioned above by using blockchain technology. We propose a blockchain-based
protocol suitable for e-health applications that does not require trust in a
third party and provides an efficient privacy-preserving access control
mechanism. Transactions in our proposed system, unlike Bitcoin, are not
entirely financial, and we do not use conventional methods for consensus
operations in blockchain like Proof of Work (PoW). It is not suitable for IoT
applications because IoT devices have resources-constraints. Usage of
appropriate consensus method helps us to increase network security and
efficiency, as well as reducing network cost, i.e., bandwidth and processor
usage. Finally, we provide security and privacy analysis of our proposed
protocol.Comment: 6 page
Block-Chain-Based Vaccine Volunteer Records Secure Storage and Service Structure
Accurate and complete vaccine volunteer’s data are one valuable asset for clinical research institutions. Privacy protection and the safe storage of vaccine volunteer’s data are vital concerns during clinical trial services. The advent of block-chain technology fetches an innovative idea to solve this problem. As a hash chain with the features of decentralization, authentication, and resistibility, blockchain-based technology can be used to safely store vaccine volunteer clinical trial data. In this paper, we proposed a safe storage method to control volunteer personal /clinical trial data based on blockchain with storing on cloud. Also, a service structure for sharing data of volunteer’s vaccine clinical trials is defined. Further, volunteer blockchain features are defined and examined. The projected storage and distribution method is independent of any third person and no single person has the complete influence to disturb the processing.
Blockchain for Genomics:A Systematic Literature Review
Human genomic data carry unique information about an individual and offer
unprecedented opportunities for healthcare. The clinical interpretations
derived from large genomic datasets can greatly improve healthcare and pave the
way for personalized medicine. Sharing genomic datasets, however, pose major
challenges, as genomic data is different from traditional medical data,
indirectly revealing information about descendants and relatives of the data
owner and carrying valid information even after the owner passes away.
Therefore, stringent data ownership and control measures are required when
dealing with genomic data. In order to provide secure and accountable
infrastructure, blockchain technologies offer a promising alternative to
traditional distributed systems. Indeed, the research on blockchain-based
infrastructures tailored to genomics is on the rise. However, there is a lack
of a comprehensive literature review that summarizes the current
state-of-the-art methods in the applications of blockchain in genomics. In this
paper, we systematically look at the existing work both commercial and
academic, and discuss the major opportunities and challenges. Our study is
driven by five research questions that we aim to answer in our review. We also
present our projections of future research directions which we hope the
researchers interested in the area can benefit from
