论文摘要
随着数据驱动方法的兴起，用于交通预测，事故预测和分析驾驶行为，个人GPS轨迹数据已成为企业和新兴数据市场的重要资产。但是，作为个人数据，GPS轨迹需要保护。特别是由于数据泄露，GPS数据所有权的验证是一个具有挑战性的问题。水印通过将出处信息编码到数据中来促进数据所有权验证。由于时空数据属性和数据修改的易于，GPS轨迹水印尤其具有挑战性。结果，现有方法仅嵌入最小的出处信息，缺乏鲁棒性。在本文中，我们提出了W -Trace - 一种基于傅立叶变换的新型GPS轨迹水印方法。我们证明了W-Trace在两个现实世界中的GPS轨迹数据集上的有效性和鲁棒性。
With the rise of data-driven methods for traffic forecasting, accident prediction, and profiling driving behavior, personal GPS trajectory data has become an essential asset for businesses and emerging data markets. However, as personal data, GPS trajectories require protection. Especially by data breaches, verification of GPS data ownership is a challenging problem. Watermarking facilitates data ownership verification by encoding provenance information into the data. GPS trajectory watermarking is particularly challenging due to the spatio-temporal data properties and easiness of data modification; as a result, existing methods embed only minimal provenance information and lack robustness. In this paper, we propose W-Trace - a novel GPS trajectory watermarking method based on Fourier transformation. We demonstrate the effectiveness and robustness of W-Trace on two real-world GPS trajectory datasets.
