The increasing number of data breaches in the healthcare sector is causing serious problems in management and storage. In addition, traditional security methods being used to protect healthcare applications are proving ineffective. This is why emerging technologies such as blockchain are offering new security approaches and processes for healthcare applications, providing data confidentiality and privacy.
