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.
