安全存储医疗记录的区块链方法研究
The Utilizing Blockchain-Based Method of the Secure Storage of Medical Records

针对医疗信息系统中存在的医疗信息记录存储的安全和隐私保护问题,结合区块链和云存储技术,提出了一个医疗记录安全存储方案.该方案利用区块链来保存医疗记录的公共信息、匿名身份和访问权限,使医疗记录的真实数据加密保存在链下存储结构中,有效实现了病人对个人医疗数据的所有权和访问权限的控制以及对敏感医疗数据的安全存储.
The security and privacy preserving of medical information records in medical information system has been addressed.A scheme for secure storage of medical records based on block chain and cloud storage technology has been proposed.It uses block chain to store public information,anonymous identities and access rights of the medical records,and the encrypted real data of the medical records is stored in the off-chain cloud storage structure.It realizes the control of the patient’s ownership and access permission to the personal medical data,and secure storage of sensitive medical data
