摘要/Abstract

摘要： 医疗数据的安全管理是确保患者隐私安全、有效开展医学诊疗与相关研究的关键。然而,现有的医疗数据管理方案大多存在透明度低、共享性差和无法保证患者隐私数据安全性的问题。通过设计一种“主-侧”链结构的可编辑区块链模型,提出了面向医疗联盟链的安全、可追责的医疗数据管理方案。该模型主链保存患者电子病历的最新信息,侧链记录历史修改证明,实现了数据管理的透明性和可追责性。引入变色龙哈希函数、秘密共享和可验证签名技术,只有通过验证的医疗机构的系统管理员才能够参与构建完整陷门,确保了医疗数据修改过程的正确性与安全性。经过安全性分析和相关实验模拟,该方案在计算开销、通信负载方面的性能较好,且在存储开销方面存在优势,表明了该方案的有效性和可行性。

Abstract: Secure management of medical data is crucial for ensuring the security of patient privacy and effectively conducting medical treatments and related research.However,most existing medical data management solutions have the problems of low transparency,inadequate sharing and fail to secure patient privacy.By designing an editable blockchain model with a “main-side” chain structure,a secure and accountable healthcare data management scheme for healthcare consortium chain is proposed.Its main chain stores current information about the patient’s electronic medical record,while the side chain records historical proof of modification,enabling the transparency and traceability of data management.Introducing chameleon hash function,secret sharing and verifiable signature technology,only verified system administrators of healthcare organizations are able to construct the complete trapdoor,which ensures the correctness and security of the medical data modification process.Security analysis and related experiment simulation show that,the proposed scheme performs well in computational overhead and communication load,as well as storage efficiency,which demonstrates its effectiveness and feasibility.
