Data batch retrieval method, system and equipment based on privacy calculation and medium

The invention relates to a data batch retrieval method, system and device based on privacy computing and a medium. After a queried party receives a retrieval instruction, unique identification values corresponding to all original data are grouped; therefore, the central platform can determine that the query data provided by the query party corresponds to the unique identification value in a certain group or a plurality of groups in the array, and sends the corresponding group number to the queried party, so that the queried party only needs to provide the original data related to the received group number to the central platform, and the query efficiency is improved. And all data does not need to be submitted to a central platform, and meanwhile, a batch retrieval method is combined, so that the retrieval time is greatly shortened, and the retrieval efficiency is improved. 本申请涉及一种基于隐私计算的数据批量检索方法、系统、设备及介质，通过在被查询方接收检索指令后，将所有原始数据对应的唯一标识值进行分组，从而使的中心平台可根据要求查询方提供的查询数据对应为唯一标识值确定其在数组中某一分组中，或者多个分组中，则将对应的分组编号发送至被查询方，这样
