The invention discloses a privacy intersection method and terminal equipment, which are characterized in that after data in a data set is divided, calculation of a target hash function is carried out, and the number of times of hash calculation is reduced. And meanwhile, the first information table and the second information table with the same dimension are subjected to multi-dimensional space mapping, so that the data are visually and quickly screened, and the calculation amount in the privacy intersection process is reduced. 本申请公开了一种隐私求交方法及终端设备，通过对数据集合中的数据分别进行划分后，进行目标哈希函数的计算，减少了哈希计算的次数。同时通过将第一信息表和相同维度的第二信息表进行多维空间的映射，直观快速对数据进行筛选，减少隐私求交过程中的计算量。
