Enabling the efficiency of Blockchain Technology in Tele-Healthcare with Enhanced EMR

- A blockchain is a growing list of records, called blocks, that are linked using cryptography. Each block contains
a cryptographic hash of the previous block, a timestamp and a transaction data. A blockchain consists of a structure of
data that represents a financial ledger entry, or a record of transactions. Each transaction is digitally signed to ensure its authenticity, therefore no one tampers with it. So the ledger itself along with an existing transactions within it are assumed to be with great integrity. The basic advantages of blockchain technology includes the features of
decentralization, Peer to peer network, immutability, security and transparency. If once the data has been re-entered into the record, it will not get deleted instead, it gets updated. Every block in the blockchain has a permanent
timestamp that indicates authentication and verification. Here, we promote the facility of having a smart contract between the patient and a healthcare sector. It highly concentrates in the field of diabetes as it is a rapidly growing disease in today’s world. It requires regular checkups to keep the disease in control. This paper consolidates the features of blockchain technology to produce an enhanced EMR in the field of diabetes.
