Abstract

The invention provides a data processing method and device based on privacy protection and a server. The method comprises the steps of: after receiving a second tag column containing ciphertext data of data tags corresponding to identification information arranged according to a first sequence, combining a first server with a second feature column containing feature numbers which are arranged according to the same sequence and respectively correspond to the same identification information; dividing ciphertext data of a plurality of data tags contained in the second tag column into a pluralityof data groups corresponding to different feature numbers; performing statistics to obtain the ciphertext sum of the data tags of each data group; receiving a first inquiry request initiated by a second server, and returning the ciphertext sum of the data tags of the data set while confirmation information is returned to the second server through the first inquiry request, so that cooperation withthe second server in a one-way network environment can be realized; and jointly carrying out data processing related to the category type feature data based on privacy protection.

Description

technical field [0001] This specification belongs to the technical field of the Internet, and in particular relates to a data processing method, device and server based on privacy protection. Background technique [0002] In many data processing scenarios, it often happens that one data party (for example, denoted as the first data party) holds characteristic data corresponding to a set of identification information (for example, category-type characteristic data), while another data party (for example, , denoted as the second data party) holds data tags corresponding to the same set of identification information. Sometimes, the second data party needs to cooperate with the first data party so that the characteristic data held by the first data party can be used to jointly carry out corresponding target data processing. [0003] However, before processing the above-mentioned target data, the second data party often needs to evaluate and process the data quality and use effe...
