Blockchain-based Personal Health Data Sharing System Using Cloud Storage

Abstract

With the advent of rapid development of wearable technology and mobile computing, huge amount of personal health-related data is being generated and accumulated on continuous basis at every moment. These personal datasets contain valuable information and they belong to and asset of the individual users, hence should be owned and controlled by themselves. Currently most of such datasets are stored and controlled by different service providers and this centralised data storage brings challenges of data security and hinders the data sharing. These personal health data are valuable resources for healthcare research and commercial projects. In this research work, we propose a conceptual design for sharing personal continuousdynamic health data using blockchain technology supplemented by cloud storage to share the health-related information in a secure and transparent manner. Besides, we also introduce a data quality inspection module based on machine learning techniques to have control over data quality. The primary goal of the proposed system is to enable users to own, control and share their personal health data securely, in a General Data Protection Regulation (GDPR) compliant way to get benefit from their personal datasets. It also provides an efficient way for researchers and commercial data consumers to collect high quality personal health data for research and commercial purposes.

Blockchain and AI-based Solutions to Combat Coronavirus (COVID-19)-like Epidemics: A Survey

“…Along with the advance of blockchain, there are some new consensus algorithms such as Proof-of-stake (PoS), Byzantine Faulty Tolerant (BFT) [24]. Blockchain has proved its success in healthcare and biomedical applications with promising performances in terms of healthcare data privacy [25], secure data management [26], [27], and transparent medical data storage [28], [29]. Therefore, it is possible to apply in solving healthcare issues related to coronavirus epidemic.…”

Dwarna: a blockchain solution for dynamic consent in biobanking

“…From a legal standpoint, Berberich and Steiner [69] mull the question of who the data controller is in the blockchain structure, where everyone has a copy of some or all of the data. Thus, ever since the GDPR came into effect, research has started looking at making blockchain-based systems that comply with the regulation [70,71].…”

“…The focus of these systems is normally the use of the blockchain to store consent for how personal data should be shared, thereby enforcing individuals' control [70,71]. This is also the case in My Health My Data, a system that aims to make patients more aware of their data and facilitate medical data sharing for research and healthcare through dynamic consent.…”

A Review on the Role of Blockchain Technology in the Healthcare Domain

“…In [85], the authors proposed an efficient approach to share continuous IoT data using blockchain. They classified the data into different categories based on data characters (static and dynamic) and data acquisition (instant and continuous).…”
