论文摘要
在这项工作中，我们介绍了CCTV暴露 - 第一个评估潜在的隐私暴露于闭路电视（CCTV）摄像机的解决方案。目的是开发一种工具集，以从隐私的角度量化人类对CCTV摄像机的接触。我们的新方法是对个体的轨迹分析，再加上一个地理位置图映射的CCTV摄像机的数据库，并以最小而充分的元信息注释。为此，将基于全球定位系统（GPS）跟踪的CCTV暴露模型应用于不同情况下的个人隐私暴露。当前的调查提供了建模方法的应用示例和验证。在这项工作中开发和实施的方法和工具集提供了暴露事件的时间序列和位置序列，从而使暴露与单个活动和摄像机之间的暴露可能联系，并提供了有关个人接触CCTV摄像机具有高时空分辨率的主要统计信息。
In this work, we present CCTV-Exposure -- the first CCTV-aware solution to evaluate potential privacy exposure to closed-circuit television (CCTV) cameras. The objective was to develop a toolset for quantifying human exposure to CCTV cameras from a privacy perspective. Our novel approach is trajectory analysis of the individuals, coupled with a database of geo-location mapped CCTV cameras annotated with minimal yet sufficient meta-information. For this purpose, CCTV-Exposure model based on a Global Positioning System (GPS) tracking was applied to estimate individual privacy exposure in different scenarios. The current investigation provides an application example and validation of the modeling approach. The methodology and toolset developed and implemented in this work provide time-sequence and location-sequence of the exposure events, thus making possible association of the exposure with the individual activities and cameras, and delivers main statistics on individual's exposure to CCTV cameras with high spatio-temporal resolution.
