Blockchain technology has become a new way to deal with the problems that healthcare data management has been having for a long time, especially when it comes to security and privacy. More and more, healthcare systems need to keep private patient information safe from leaks, illegal access, and changes. Cyberattacks are becoming more likely against traditional controlled data store models. This makes blockchain's autonomous design a hopeful answer. This study looks into how blockchain-based systems might be able to make hospital data handling safer and more private. By using blockchain's main features immutability, openness, and digital security healthcare providers can make sure that data is correct, make it safe for patients to share data, and keep strict privacy controls. This essay takes a look at how healthcare data is managed now, lists the main privacy and security issues, and gives a thorough breakdown of blockchain options. The study shows through a case study how blockchain can be added to current healthcare systems. Smart contracts and consensus methods are used to make sure that data transfers are trustworthy and accountable. The study also looks at how well blockchain systems work in terms of how fast transactions happen, how well they can be scaled, and how much they cost. It also looks at how well they protect data privacy and security.
