In order to withstand the ever-increasing invasion of privacy by CCTV cameras and technologies, on par CCTV-aware solutions must exist that provide privacy, safety, and cybersecurity features. We argue that a first important step towards such CCTV-aware solutions must be a mapping system that provides both privacy and safety routing and navigation options. To the best of our knowledge, there are no mapping nor navigation systems that support privacy and safety routing options. In this paper, we explore the feasibility of a CCTV-aware routing and navigation solution. The aim of this feasibility exploration is to understand what are the main impacts of CCTV on privacy, and what are the challenges and benefits to building such technology. We evaluate our approach on seven (7) pedestrian walking routes within the downtown area of the city of Jyvaskyla, Finland. We first map a total of 450 CCTV cameras, and then experiment with routing and navigation under several different configurations to coarsely model the possible cameras' parameters and coverage from the real-world. We report two main results. First, our preliminary findings support the overall feasibility of our approach. Second, the results also reveal a data-driven worrying reality for persons wishing to preserve their privacy/anonymity as their main living choice. When modelling cameras at their low performance end, a privacy-preserving route has on average a 1.5x distance increase when compared to generic routing. When modelling cameras at their medium-to-high performance end, a privacy-preserving route has on average a 5.0x distance increase, while in some cases there are no privacy-preserving routes possible at all. These results further support and encourage both global mapping of CCTV cameras and refinements to camera modelling and underlying technology.

用于隐私、匿名和安全的闭路电视感知路由和导航的可行性研究。于韦斯屈莱——第一个受益于闭路电视感知技术的城市的案例研究。（预印本）

为了抵御闭路电视摄像机和技术对隐私不断增加的侵犯，必须存在同等的闭路电视感知解决方案，以提供隐私、安全和网络安全功能。我们认为，迈向此类 CCTV 感知解决方案的第一个重要步骤必须是提供隐私和安全路线和导航选项的地图系统。据我们所知，没有支持隐私和安全路线选择的地图或导航系统。在本文中，我们探讨了闭路电视感知路由和导航解决方案的可行性。此可行性探索的目的是了解闭路电视对隐私的主要影响是什么，以及构建此类技术的挑战和好处是什么。我们在芬兰于韦斯屈莱市中心区的七 (7) 条步行步行路线上评估了我们的方法。我们首先绘制了总共 450 个闭路电视摄像机的地图，然后在几种不同的配置下尝试路由和导航，以粗略地模拟现实世界中可能的摄像机参数和覆盖范围。我们报告了两个主要结果。首先，我们的初步发现支持我们方法的整体可行性。其次，对于希望将隐私/匿名作为主要生活选择的人来说，结果还揭示了一个数据驱动的令人担忧的现实。在对低性能端的摄像头建模时，与通用路由相比，隐私保护路由的距离平均增加了 1.5 倍。在中高性能端建模相机时，一条隐私保护路线的距离平均增加了 5.0 倍，而在某些情况下，根本没有隐私保护路线。这些结果进一步支持和鼓励闭路电视摄像机的全球映射以及对摄像机建模和底层技术的改进。
