关于城市与移动供应商之间的数据之争（CS CY）---刘持诚

电动滑板车正在改变着人们的交通习惯。为了监督踏板车的使用情况，洛杉矶交通部提出了一个规范，要求踏板车公司提供踏板车使用的详细数据。在这项工作中，我们首先认为洛杉矶交通部要求使用新规范的数据要求是没有必要的，因为所提出的使用案例可以通过现有的规范来满足。其次，我们证明，即使是现有的规范，要求公司发布停放的滑板车的实时数据，也会使使用滑板车的个人隐私受到威胁。然后，我们提出了一种算法，在发布停放的踏板车数据时，可以实现正式隐私和实用性保障，让城市当局在保护骑行者隐私的同时，满足他们的使用需求。

原文题目：On the Data Fight Between Cities and Mobility Providers

原文：E-Scooters are changing transportation habits. In an attempt to oversee scooter usage, the Los Angeles Department of Transportation has put forth a specification that requests detailed data on scooter usage from scooter companies. In this work, we first argue that L.A.'s data request for using a new specification is not warranted as proposed use cases can be met by already existing specifications. Second, we show that even the existing specification, that requires companies to publish real-time data of parked scooters, puts the privacy of individuals using the scooters at risk. We then propose an algorithm that enables formal privacy and utility guarantees when publishing parked scooters data, allowing city authorities to meet their use cases while preserving riders' privacy.
