一种基于差分隐私的位置隐私保护算法

A Location Privacy Protection Algorithm Based on Differential Privacy

近年来,移动终端科技和GPS定位技术飞速发展,人们随时随地获取自身的位置信息数据成为现实。这给人们带来极大方便的同时也不可避免地带来了一系列问题,其中最突出的就是位置数据隐私保护问题。笔者提出一种结合差分隐私技术的位置隐私保护算法,力求在保证隐私保护程度的前提下,寻找到其与服务质量之间的平衡。

In recent years, mobile terminal technology and GPS positioning technology have developed rapidly. People can obtain their own location information data anytime and anywhere. This brings great convenience to people and inevitably brings with it a series of troublesome issues. The most acute and prominent one is the problem of location data privacy protection. The author proposes a location privacy protection algorithm combined with differential privacy technology, and strives to find a balance between it and the quality of service on the premise of ensuring privacy protection.
