    Contact tracing is a tool for controlling infectious disease outbreaks. To foster widespread adoption, established tracing protocols focus on smartphone users. As a result, user groups who cannot afford a compatible smartphone cannot carry it continuously are left out. This work introduces the Contact Tracing Wristband (CWB) and its integration into Google and Apple’s Exposure Notification protocol. The wristband’s low-cost and versatility bring tracing to additional users and thus enhance the efficacy of tracing.

    Contact tracing helps to predict and prevent the spread of viruses. This work proposes Tracey for decentralized, privacy-preserving tracing. Unlike automated tracing solutions that operate in the background, such as the widespread governmental Corona Tracing Apps, our system builds on manual contact exchanges to ensure reliable contact tracing even for groups and venues. The devices share secrets that allow anonymous notifications using the health authorities’ trusted database. This work illustrates the concept, provides initial security analysis, first results, and gives an outlook on possible extensions.
