ABAC Scheme on Electronic Health Records Using Hyperledger Fabric

In this modern world, data is getting more significant with new emerging tech- nologies, and a transparent system must be made security mechanisms.For example, an Electronic Health Record (EHR) that records patient in digital format across different healthcare settings. The ulti- mate benefits of Blockchain technology are to safeguard pave path for health centers, clinics, medicals. A high-level invulnerable required prevent the rising cybersecurity threats targeting these organizations. fulfills HIPAA regulation protective barrier transparency by many fields. Attribute-based access con- trol (ABAC) scheme provides effective authentication autho- rization model considers attributes from user, instead roles, grant permission user access. This makes it easier Certificate Authorities (CA) manage permissions assigning specific rights privileges based on individual’s characteristics. Thus, writing policies will secure as one requested can only view if they satisfy policy’s criteria.
