Abstract: A number of devices co-located at a geographic location can broadcast and receive tokens. Tokens can be exchanged using a communication link having limited communication range. Tokens that are received by a device can be stored locally on the device and/or transmitted to a trusted service operating remotely on a network. In some implementations, the tokens can be stored with corresponding timestamps to assist a trusted service in matching or otherwise correlating the tokens with other tokens provided by other devices. The trusted service can perform an analysis on the tokens and timestamps to identify devices that were co-located at the geographic location at or around a contact time which can be defined by the timestamps. A group can be created based on results of the analysis. Users can be identified as members of the group and invited to join the group.

Abstract translation: 位于地理位置的多个设备可以广播和接收令牌。 可以使用具有有限通信范围的通信链路来交换令牌。 由设备接收的令牌可以本地存储在设备上和/或被发送到在网络上远程操作的受信任的服务。 在一些实现中，令牌可以以对应的时间戳存储，以协助可信服务以匹配或以其他方式将令牌与由其他设备提供的其他令牌相关联。 信任的服务可以对令牌和时间戳进行分析，以识别在时间戳可以定义的联系时间周围或周围地理位置处共处的设备。 可以根据分析结果创建一个组。 用户可以被识别为该组的成员，并被邀请加入该组。
