DEMRISEC: security enhancement of patient data in decentralized medical records with IPFS

연구 분야: Databases

Every minute, attackers with some form of breach target the healthcare industry. The most targeted components in this context are electronic health records (EHRs), electronic medical records (EMRs), and personally identifiable information (PII). The healthcare industry is implementing technologies that ensure security and privacy to prevent such incidents. This is accomplished through blockchain technology, as cryptography is one of its foundational components. Blockchain technology guarantees the validity, integrity, and confidentiality of data throughout the network. However, large files cannot be conveniently stored directly on the blockchain. Decentralized and distributed blockchain technology is used in conjunction with the InterPlanetary File System (IPFS) to address this challenge. In this essay, we propose a secure healthcare system that combines a global file system with blockchain technology. The primary goals of this endeavor are to enhance data user control, storage management, security, and privacy. To achieve this, the Edward-curve Digital Signature Algorithm (EdDSA) is used as a consensus mechanism for authentication. The InterPlanetary File System (IPFS), which utilizes a built-in hashing algorithm, is added as off-chain storage to safeguard file integrity. All information exchange across nodes is encrypted. Tests were conducted to evaluate the effectiveness, security, and privacy of the proposed system. The findings of our analysis and comparison with previously offered schemes indicate that the suggested system performs better in terms of security and privacy. The results obtained from the experiment demonstrate that the proposed system offers significant improvements over previous systems. It exhibits faster file upload speeds, a higher transaction rate, and achieves efficient encryption using fewer bits.
