Block Chain:A Key role in health sector

A block chain is a way to circulate, public ledger, recording transaction and tracking assets, and of which immutability is guaranteed by a peer-to-peer network of computers, not by any centralized authority.  A block chain is a latest technology which consists of ordered records arranged in a form of blocks. Each data block contains a hash (digital fingerprint or unique identifier), timestamped batches of recent transactions, and a hash of the previous block.

With this mechanism, the data on the block chain network are immutable in all sectors along with an import role in healthcare sector

. In the world of healthcare today, there are two major attentions are required that must be addressed: data security and data ownership. It’s become more important in the post  pandemic situation of Covid 19. Sensitive medical records currently lack a secure structure, leading to data breaches with severe consequences. Many features of block chain technology, such as the immutability of the data stored in a block chain, are drawing the attention of the healthcare sector, and rosy prospects for many available cases are being discussed. Block chain technology is expected to improve medical record management and the insurance claim process, accelerate clinical and biomedical research, and advance biomedical and healthcare data ledger.

Block chain technology simplify the transition from institution-driven interoperability to patient-centred interoperability.

This technology also helps the Doctors to remote monitoring of their patient, Through this technology during the lockdown of COVID 19 Doctors have continuously monitored their patient in Mumbai, Chennai and lot many other cities.

 Block chain technology permits patients to assign access rules for their medical data, for example, permitting specific researchers to access parts of their data for a fixed period of time. With block chain technology, patients can connect to other hospitals and collect their medical data automatically..

From health application, Health Data Gateway to prevention of data everything can be taken care with the help of this advanced technology.
