专利摘要显示，本申请提供了一种基于区块链的关联关系查询方法、装置与存储介质。该方法包括：配置查询程序模块对第一关注主键进行椭圆曲线乘法计算，得到第一查询中间结果，并推送至区块链；配置合作程序模块收到区块链的通知，根据第一查询中间结果确定第一查询结果，推送至区块链；配置合作程序模块对第二业务主键进行椭圆曲线乘法计算，得到第二查询中间结果，至少将第二查询中间结果推送至区块链；配置查询程序模块接收到区块链的通知，根据第二查询中间结果计算得到第二查询结果，并与第一查询结果比对，得到有效关联关系结果。通过将隐私计算过程与区块链密切整合，计算的过程均在区块链上留痕，解决了对隐私计算过程的监督和审计不易操作的问题。
The patent summary shows that the application provides a linkage search method, device and storage medium based on the block chain. This methodology includes: the configuration search program module, which calculates the elliptical curve of the first concern key by multiplying it to the block chain; the configuration cooperation process module, which receives notification of the block chain from the first concern key; the configuration cooperation process module, which determines the first search result based on the first query intermediate result and sends it to the block chain; the configuration cooperation process module, which calculates the elliptical curve of the second business key by multiplying the second query intermediate result, and at least forwards the second query intermediate result to the block chain; the configuration search process module, which receives notification of the block chain based on the second query intermediate result, which calculates the second search result and is compared to the first search result, is effectively linked to the result. By closely integrating the privacy calculation process with the block chain, the calculation process leaves marks on the block chain, resolving the problems of monitoring and auditing the privacy calculation process, which are not easy to operate.
