Data hiding query method, apparatus and device, and computer program product

The invention relates to the field of data services, and provides a data hiding query method, device and equipment and a computer program product. The data hiding query method comprises the steps of obtaining comparison data and a first identification compression value corresponding to the comparison data, and determining an identification compression value set corresponding to the first identification compression value; converting to-be-compared data corresponding to the identification compression value set into to-be-compared values; and comparing the comparison data with the to-be-compared numerical values to obtain a comparison result, and determining a data hiding query result according to the comparison result. Through data conversion and numerical value comparison, data query and comparison are realized under the condition that data are not leaked. 本申请涉及数据业务领域，提供一种数据隐匿查询方法、装置、设备及计算机程序产品。所述数据隐匿查询方法包括：获取比较数据及所述比较数据对应的第一标识压缩值，确定所述第一标识压缩值对应的标识压缩值集合；将所述标识压缩值集合对应的待比较数据转化为待比较数值；将所述比较数据与各所述待比较数值进行比较，得到比较结果，根据所
