摘要

当试图在组织之间共享数据时,行业仍然面临挑战,特别是当数据来自不同的数据库管理系统(DBMS)和不同的DBMS模式时。另一个担忧是,隐私法可能要求某些类型的数据在本地访问策略下受到保护。我们描述了一个使用下一代数据库访问控制(NDAC)和数据块矩阵(DBM)的安全数据共享解决方案。讨论了一个临床试验数据用例,以及使用Hyperledger Fabric的DBM的概念验证实现的描述。所描述的解决方案允许访问数据所在的位置,而不是交换或集中存储。此外,它通过使用一种满足“删除权”要求的分布式账本技术,解决了传统区块链使用与隐私法规之间的冲突。

A Distributed Ledger Technology Design using Hyperledger Fabric and a Clinical Trial Use Case
Industry continues to be challenged when attempting to share data among organizations, especially when the data comes from different database management systems (DBMS) and different DBMS schemas. Another concern is that privacy laws may require some types of data to be protected under local access policies. We describe a secure data sharing solution using Next-generation Database Access Control (NDAC) and the Data Block Matrix (DBM). A clinical trial data use case is discussed, as well as a description of a proof-of-concept implementation of the DBM using Hyperledger Fabric. The solution described allows data access where the data resides, rather than exchanging or being centrally stored. Additionally, it solves the conflict between conventional blockchain use and privacy regulations, by using a form of distributed ledger technology that meets ‘right to erasure’ requirements.
