Abstract
Blockchain technology has an enormous scope to revamp the healthcare system in many ways as it improves the quality of healthcare by data sharing among all the participants, selective privacy and ensuring data safety. This paper explores the basics of blockchain, its applications, quality of experience and advantages in disease surveillance over the other widely used real-time and machine learning techniques. The other real-time surveillance systems lack scalability, security, interoperability, thus making blockchain as a choice for surveillance. Blockchain offers the capability of enhancing global health security and also can ensure the anonymity of patient data thereby aiding in healthcare research. The recent epidemics of re-emerging infections such as Ebola and Zika have raised many concerns regarding health security which resulted in strengthening the surveillance systems. We also discuss how blockchains can help in identifying the threats early and reporting them to health authorities for taking early preventive measures. Since the Global Health Security Agenda addresses global public health threats (both infectious and NCDs); strengthen the workforce and the systems; detect and respond rapidly and effectively to the disease threats; and elevate global health security as a priority. The blockchain has enormous potential to disrupt many current practices in traditional disease surveillance and health care research.
Highlights
In recent years, blockchain technology has gained significant attention among several diverse areas and domains, including healthcare, as it offers a safer and distributed database that can operate effectively without the need for a centralized administrator
It could help track information for ongoing public health blockchain technology can be shared among a network of computers
Apart from that, it was emphasized by Woods that this combination of Artificial Intelligence (AI) with blockchain could tackle the security threats faced by the Internet [21]
Summary
Blockchain technology has gained significant attention among several diverse areas and domains, including healthcare, as it offers a safer and distributed database that can operate effectively without the need for a centralized administrator. Apart from that, blockchain has gained a lot of attention and interest as an effective platform to improve both the authenticity and transparency of healthcare data in the institutions and hospitals ranging from maintaining permissions in electronic health records (EHR) to streamlining the processing of patient claims [1]. According to Angraal et al, the highlight of the blockchain environment is that once there is digital validation, Big Data Cogn. 22 of According to Angraal et al, the highlight of the blockchain environment is that once there is digital the network itself validates transaction, secures the transaction history, and allows forallows assetsfor to validation, the network itselfthe validates the transaction, secures the transaction history, and be transferred directly between parties [2].
