Differential privacy-based service analysis method and apparatus

Abstract

This specification provides differential privacy-based service analysis methods and apparatuses. According to the methods, the methods include at least one service analysis stage, and any service analysis stage includes at least one round of operations. An nround of operations of the service analysis stage include the following steps: obtaining target data, where the target data are obtained by performing anonymization processing on to-be-processed data; performing predetermined service analysis on the target data; and if the service analysis succeeds, ending the service analysis stage; or if the service analysis fails, determining an (n+1)round of privacy budget, and sending the (n+1)round of privacy budget to the multiple user devices. As such, in a process of performing differential privacy processing on data, a privacy budget can be adaptively adjusted to enhance flexibility of a privacy protection process and improving availability of privacy protection data.
