Abstract:

Since many transactions worldwide are now digitalized, data security, data sharing, fast access to data, and protecting data integrity have been considered necessary. With each passing day, our dependence on computers in our daily lives and data formation in parallel with this dependence is a part of the natural whole. This large data community has also increased the importance of data security. The word that has been heard most recently about data security is blockchain. Blockchain is a public digital ledger that records transactions across multiple computers, designed to ensure secure data sharing and maintain decentralized data transaction integrity, and cannot be changed retrospectively afterward. In recent years, cloud-based Electronic Health Records (ESK) have become the focus of attention of many researchers for remote access to patient data. The accuracy and confidentiality of patient data is a significant concern in the healthcare industry. This study proposes a new blockchain-supported solution for sharing health data between cloud service providers while providing access control and control for IHC records. The proposed method aims to transition from the management and control of the patient's electronic health records by the health sector to a patient-centered application where the patients' data are in control.
