论文摘要
我们提出了一项分散的数字联系跟踪服务，该服务通过设计来保留用户的隐私，同时遵守最高的安全标准。我们的方法基于蓝牙，并衡量人的实际相遇，接触时间段，并估计接触的距离。我们追踪用户的联系以及传染病的可能传播，同时防止用户的位置跟踪，以保护其数据和身份。我们根据流行病学模型来验证并改善跟踪的影响。我们从法律角度比较了一种集中式和分散的方法，并认为选择比例性和数据最小化的分散方法。
We propose a decentralized digital contact tracing service that preserves the users' privacy by design while complying to the highest security standards. Our approach is based on Bluetooth and measures actual encounters of people, the contact time period, and estimates the proximity of the contact. We trace the users' contacts and the possible spread of infectious diseases while preventing location tracking of users, protecting their data and identity. We verify and improve the impact of tracking based on epidemiological models. We compare a centralized and decentralized approach on a legal perspective and find a decentralized approach preferable considering proportionality and data minimization.
