Strengthening public health surveillance through blockchain technology

In this 2019 paper published in AIMS Public Health, Bhattacharya et al. argue for the benefits of using blockchain technology in public health surveillance. Noting the transparency and trust aspects of the technology, as well as the benefits of ” data security and privacy, cost-effectiveness, and verifiability of data,” the authors discuss four primary ways blockchain can be applied to healthcare activities, including community disease surveillance. “Blockchain could help independent organizations to manage data more efficiently during pandemics,” they note, particularly in unison with machine learning and AI techniques. They conclude that blockchain-based disease surveillance “can be more effective and rapid than traditional surveillance in terms of coverage, durability, consensus, selective privacy, uniqueness, and timing.”
