Abstract

As healthcare services have become increasingly digitized, Electronic Health Records (EHRs) have become widely adopted, providing seamless data exchange among providers. Conventional EHRs, however, are extremely vulnerable to cyber threats because patients' sensitive data is centralized and transmitted electronically. The paper proposes a decentralized, privacy-preserving framework for managing EHRs on blockchains in order to address these security and privacy concerns. Using cryptographic techniques, such as homomorphic encryption and zero-knowledge proofs, the proposed system enhances security and ensures data integrity. Additionally, the model facilitates scalable, efficient, and secure access to patient records through the integration of cloud-based storage and blockchain. Using smart contracts, we also ensure compliance with healthcare regulations by regulating access control and authentication. As a result of performance evaluations, the proposed approach is demonstrated to be feasible, and the advantages it offers in terms of security, privacy, and efficiency are highlighted.
使用区块链的分散和隐私保护的电子健康记录框架
随着医疗保健服务日益数字化,电子健康记录(EHRs)已被广泛采用,在提供者之间提供无缝的数据交换。然而,传统的电子病历极易受到网络威胁,因为患者的敏感数据是集中的,并以电子方式传输。本文提出了一个分散的、保护隐私的框架,用于管理区块链上的电子病历,以解决这些安全和隐私问题。采用同态加密和零知识证明等密码学技术,提高了系统的安全性,保证了数据的完整性。此外,该模型通过集成基于云的存储和区块链,促进了对患者记录的可扩展、高效和安全访问。使用智能合约,我们还通过规范访问控制和身份验证来确保遵守医疗保健法规。作为性能评估的结果,所提出的方法被证明是可行的,并且它在安全性、隐私性和效率方面提供的优势被突出。
