Abstract

An embodiment of the present invention provides a random response-based personalized privacy protection method and device, wherein the method is applied to the client, including: obtaining the target sensitivity value input by the user to collect target privacy data, the target privacy The data corresponds to a plurality of sensitive values, and the target sensitive value is a sensitive value among the plurality of sensitive values; using a preset personalized random response model, the target sensitive value is disturbed to obtain a disturbed sensitive value; Wherein, the model is a response model that introduces the weight of each sensitive value of the target privacy data, and the model makes: the probability of outputting the real value for the sensitive value with high weight is lower than the probability of outputting the real value for the sensitive value with low weight The probability. This solution can solve the problem of over-protection of some privacy data and insufficient protection of some privacy data in the process of privacy collection in the existing random response-based related technologies.

Description

technical field [0001] The invention relates to the technical field of privacy data protection, in particular to a random response-based personalized privacy protection method and device. Background technique [0002] The data is a reflection of the specific situation of the surveyed object in real life. In order to carry out various surveys and studies, researchers (data collectors) usually ask questions to the surveyed objects (data providers / participants / respondents) through questionnaires and other methods to obtain the required survey data. However, the respondents' answers often contain extremely sensitive personal information, and the direct collection of these data by data collectors may lead to serious personal privacy leakage. [0003] In the prior art, Warner proposed for the first time in 1965 the use of Randomized Response (RR) technology (hereinafter referred to as W-RR) to collect privacy-sensitive data. The localized privacy protection mechanism based on RR...
