Defending Delicate Health Information with Corda Blockchain Enabled MAC and UCON-Based Access Controls via IPFS

doi:10.23940/ijpe.24.01.p7.4855

Abstract

Abstract: Medical data is incredibly sensitive to privacy issues and comprises much personal information. Medical data must be correctly and securely kept in the era of big data due to the growing digitization of the healthcare industry. However, sharing current health information is challenging and prone to the danger of privacy breaches. This article suggests a healthcare information security storage solution based on the Mandatory Access Control and Usage Control (UCON) architecture and the Corda Blockchain to address these problems. The plan uses Mandatory Access Control (MAC) and Usage Control (UCON), which permits dynamic and granular access to medical data before storing the data on the blockchain, which can be made secure and impenetrable by creating relevant smart contracts. Furthermore, this solution integrates IPFS technology to alleviate the blockchain's storage load. Experiments show that the proposed scheme in this paper, which combines Mandatory Access Control (MAC), Usage Control (UCON), and blockchain technology, not only ensures the secure storage and integrity of medical information but also defines usage policies that specify how sensitive data can be used.

Key words: blockchain, health information, MAC, UCON, IPFS, corda
