To protect personal patient information and comply with regulations, data security is a necessary aspect of the healthcare business. Systems in the healthcare business that are based on the block chain are beneficial to both medical professionals and patients. The use of block chain technology in the healthcare industry as a useful tool for decentralizing patient health information, monitoring pharmaceutical goods, and increasing payment options is swiftly gaining support. Because patient data is written on paper and stored in filing cabinets, it is simple to protect and secure it. However, all data is now saved digitally, such as patient records, which are now stored on computers, servers, and storage devices. Poor wireless network security, data breaches, legacy system use, malware, viruses, and other hostile attacks are all risk considerations in health care. When compared to other businesses, one of the key reasons to safeguard health care data is that healthcare companies gather and keep extremely detailed patient records, including patient names, dates of birth, addresses, and social security numbers. This paper aims to discuss the issues and solutions to achieving digital healthcare using blockchain technology.
