Blockchain technology for protection of biomedical documents in healthcare society

Blockchain is around a decade-old technology that initially came with Bitcoin to protect digital monetary transactions with consensus and mining incentives. Later on, blockchain technology is adopted by different domains, including banking, healthcare and governance, to mention a few. The Healthcare industry is massive in a world where data security is indispensable. Since biomedical research documents are content-sensitive with evidence-based research, it is essential to see data integrity and non-repudiation besides other security attributes. Blockchain is the technology found suitable for achieving the desired level of security for biomedical documents. This paper investigates the present state-of-the-art on the application of Blockchain to biomedical databases. Our contribution is to analyse and compare existing methods with a tabulated study. Based on specific investigations, we conclude that biomedical databases are protected through blockchain technology, making those data more reliable and helping to provide effective diagnosis and treatment to the patients in the hospital.
