Before discussing the role of blockchain in healthcare data security, what is blockchain technology? And how does it work? Let’s explain it briefly.
What is blockchain technology? ➤ Role of blockchain in healthcare data security
Blockchain is a decentralized digital ledger, which is distributed among different nodes (computers). Each node contains a full copy, and each block contains a fixed amount of data. Whenever new data is added, it is added to a new block. These changes are updated on each node. Blockchain data is resistant to being changed, deleted, or edited.
Because it uses a cryptographic hash function. which can detect attempts to modify data. This technology is best known for cryptocurrencies, especially Bitcoin, but it is also being used in other areas.
Healthcare data and security requirements
Healthcare data is usually personal and sensitive. which includes the patient’s medical history, treatment, diagnosis, and other health-related information. If this data falls into the hands of criminals. However, it may violate patient privacy and cause harm to healthcare providers. To understand the importance of healthcare data security, it must be remembered that ensuring the privacy and security of healthcare information is a matter of patient rights and trust.
Blockchain technology and Healthcare data security (Role of Blockchain in healthcare data security)

Which is not in blockchain technology. Because every node in the blockchain has a copy, even if a single node is attacked, the entire system’s data is protected.
Data Integrity Assurance:
Blockchain technology helps ensure data integrity. Each block is cryptographically hashed. It is connected to the previous block. In this way, if a block’s data is changed, it will not immediately match the entire chain. It can detect attempts to change.
Privacy and Encryption:
Data can be encrypted using blockchain. which only authorized persons can access. Encryption ensures data privacy. Protects against data breaches. In the healthcare sector, patient information can only be shared with the medical provider, and the possibility of falling into the hands of third parties is reduced.
Chain of custody of blockchain in healthcare data security
An important aspect of healthcare data is the chain of custody or history of data transfers. Blockchain technology can record the chain of custody of data in a reliable, and automated manner. Accurate records are kept of when, how, and by whom any information is accessed. which can be used later for audit.
Identity verification of blockchain in healthcare data security
Blockchain technology can be useful in identity verification. It is very important to verify a user’s identity before gaining access to healthcare data. The process of identity verification can be automated and secured using blockchain.
