Every patient's information about medicine prescription and their history of illness in a medical record can be misguided or hacked, causing doctors a problem for proper treatment. Misplacement of medical records may lead to the wrong medication/surgery. Health care systems are less secure to storing secure medical record. Since block chain is a distributed, decentralized ledger, it has an important role in the safety measures of data and transactions. Block chain has been merging into the area of health care systems; it protects the medical record from hackers. These papers provide safety for medical records and allow patients to know about ongoing treatment and transaction procedures of it. Here only patients and doctors can act as information of record. Here, the patient data can not be accessed by any third party or others.
