eHealth Data Access Management with Privacy Protection by using Blockchain Technology and Attribute based Encryption
Ashmila KP
Abstract: eHealth is a connection of health related organisations to transfer medical data. Medical data are the private information of each patient. People consults so many doctors, each of them stores prescriptions in their servers. Sharing of medical data through any unsecure media causes unauthorised access or misuse of information. The usage of blockchain and attribute based encryption allows the secure sharing of medical and personnel data between health organizations, establishing trust among parties involved. However, due to the replication of the blockchain on multiple nodes, a significant amount of storage space is required, which may not have an immediate purpose. To address this issue, the proposed solution combines the Ethereum blockchain with IPFS distributed storage technology to create a data sharing platform that prioritizes data security. The proposed model uses Attribute-based encryption (CP-ABE). Which is considered as more secure than traditional public-key encryption.
