高效用移动数据的隐私保护发布

Privacy-preserving Publication of Mobility Data with High Utility

Vincent Primault, Sonia Ben Mokhtar, Lionel Brunie

摘要:

每天通过不同的手段收集越来越多的移动性数据,例如,移动电话运营商。这些数据有时会在应用简单的匿名化技术后发布,这可能会导致严重的隐私威胁。本文提出了一种新的解决方案,其新颖性是双重的。首先,我们介绍了一种算法,该算法旨在隐藏用户在行程中停留的地方(即兴趣点),通过沿其轨迹强制执行恒定的速度。其次,我们利用用户见面的地方来交换他们的轨迹,从而混淆攻击者。

英文摘要:

An increasing amount of mobility data is being collected every day by different means, e.g., by mobile phone operators. This data is sometimes published after the application of simple anonymization techniques, which might lead to severe privacy threats. We propose in this paper a new solution whose novelty is twofold. Firstly, we introduce an algorithm designed to hide places where a user stops during her journey (namely points of interest), by enforcing a constant speed along her trajectory. Secondly, we leverage places where users meet to take a chance to swap their trajectories and therefore confuse an attacker.
