Abstract

The most liked blockchain healthcare application at present is safeguarding our critical medical data. There are many security issues that the healthcare sector must deal with. Between July 2021 and June 2022, 692 significant healthcare data breaches were revealed. The thieves grabbed information from banks, credit cards, health data, and genomic tests. Data on the blockchain is incorruptible, decentralized, and transparent, which makes it perfect for security applications. Furthermore, blockchain protects the confidentiality of medical data by being transparent and private, hiding anyone’s identity with intricate and secure algorithms. Patients, medical professionals, and healthcare providers may simply and securely exchange the same information thanks to the technology’s decentralized nature. Blockchain applications enable the accurate identification of medical errors, including risky ones. Blockchain technology significantly contributes to the handling of fraud in clinical trials. In this case, the technology may increase data efficiency in the healthcare sector. By supporting a distinct data storage pattern, the system can aid in preventing data manipulation in the healthcare industry. It guarantees adaptability, connectivity, accountability, and data access authentication. The confidentiality and safety of health records are essential for different purposes. Healthcare data can be digitized and protected in a decentralized manner with blockchain technology.
