基于差分隐私的隐私保护数据发布研究综述

Research Overview of Privacy Protection Data Release Based on Differential Privacy

随着大数据时代的发展,利用数据分析和发布等发挥数据价值的需求与日俱增,如何保护隐私数据和防止敏感数据信息的泄露成为数据安全领域研究的重点。差分隐私是2006年Dwork提出的一种新的隐私保护机制,在数据分享时定义隐私,保证数据可用性的数据发布面临的隐私保护问题,防止基于背景知识的攻击。本文介绍差分隐私的基础理论和目前数据发布的研究进展,总结差分隐私在其他领域的应用。

With the development of the era of big data,the demand for exploiting the value of data through data analysis and publishing is increasing.How to protect private data and prevent the leakage of sensitive data has become a key issue in the security field.Differential privacy is a new privacy protection mechanism proposed by Dwork in 2006.It defines privacy during data sharing,guarantees the privacy protection problems faced by data release that guarantees data availability,and prevents attacks based on background knowledge.This article introduces the basic theory of differential privacy and the current research progress of some data release,and summarizes the application of differential privacy in other fields.
