电子健康记录 (EHR) 允许患者使用开放渠道（即互联网）在家庭成员、医疗保健提供者和其他第三方数据用户之间控制、共享和管理他们的健康记录。因此，在这样的环境中，隐私、机密性和数据一致性是主要挑战。尽管基于云的 EHR 解决了上述讨论，但它们容易受到各种恶意攻击、信任管理和服务器之间的不可否认性。最近，由于不可篡改的特性，引入了区块链技术作为实现隐私和安全保护的 EHR 共享的吉祥解决方案。受上述争论的启发，我们提出了 BFHS，一种基于区块链的细粒度安全 EHR 共享机制。在 BFHS 上，我们使用基于密文策略属性的加密 (CP-ABE) 对 EHR 进行加密，并将其上传到行星际文件系统 (IPFS) 进行存储，同时通过代理重加密对匹配索引进行加密并保存在医疗联盟区块链中。此外，我们创建了信用评估机制并将其纳入智能合约。智能合约、代理重加密、信用评估机制和 IPFS 协同工作，为患者提供值得信赖的 EHR 共享环境和动态访问控制界面。深入的对比和实验分析表明，所提出的BFHS具有更全面的安全特性，更具有实用性。而匹配索引通过代理重新加密进行加密，并保存在医疗联盟区块链中。此外，我们创建了信用评估机制并将其纳入智能合约。智能合约、代理重加密、信用评估机制和 IPFS 协同工作，为患者提供值得信赖的 EHR 共享环境和动态访问控制界面。深入的对比和实验分析表明，所提出的BFHS具有更全面的安全特性，更具有实用性。而匹配索引通过代理重新加密进行加密，并保存在医疗联盟区块链中。此外，我们创建了信用评估机制并将其纳入智能合约。智能合约、代理重加密、信用评估机制和 IPFS 协同工作，为患者提供值得信赖的 EHR 共享环境和动态访问控制界面。深入的对比和实验分析表明，所提出的BFHS具有更全面的安全特性，更具有实用性。

A fine-grained and secure health data sharing scheme based on blockchain

Electronic health record (EHR) allows patients to use an open channel (ie, Internet) to control, share and manage their health records among family members, healthcare providers and other third party data users. Thus, in such an environment, privacy, confidentiality, and data consistency are the major challenges. Although cloud-based EHR addresses the aforementioned discussions, these are prone to various malicious attacks, trust management and non-repudiation among servers. Recently, due to the property of immutability, blockchain technology has been introduced to be as an auspicious solution for achieving EHR sharing with privacy and security preservation. Motivated by the above debates, we present BFHS, a blockchain-based fine-grained secure EHR sharing mechanism. On BFHS, we encrypt the EHR using ciphertext-policy attribute-based encryption (CP-ABE) and upload it to the interplanetary file system (IPFS) for storage, while the matching index is encrypted via proxy re-encryption and kept in a medical consortium blockchain. In addition, we created a credit assessment mechanism and incorporated it into the smart contract. Smart contracts, proxy re-encryption, a credit evaluation mechanism, and IPFS all work together to give patients with a trustworthy EHR sharing environment and a dynamic access control interface. The thorough comparison and experimental analysis show that the proposed BFHS has more comprehensive security features and is more practicable.
