The health economy has been an innovative technology since time-honored. Preserving andmaintaining patient data are essential in a routine life. Patient’s medical information is very important for every individual not only for patients but also for doctors who are examining them .We use the idea of Blockchain technology in healthcare to monitor these details and protect each person's personal information. Building a health information invention without the connectivity of a shady third-party infrastructure is a worry for the health economy. Due to the accessibility problems and leakage of information faced by the hospital management in other technologies.we come up with SHA-512(Secure Hashing Algorithm) which converts the patient information into the hash value using Ethereum platform.which will stop unauthorized entry.Electronic Health Records are essential to integrating with blockchain technology and smart contracts because SHA-512 offers greater protection than the other algorithms.
