    • Systems and methods for proximity detection between electronic devices are disclosed. One or more electronic devices transmit signals to a proximity server, which determines whether the first electronic device may be proximate the second electronic device. The proximity server transmits a signal to the first electronic device and the second device, and in response to the signal, the first and second electronic devices activate an environmental sensor, collect at least one sample of environmental data, extract at least one feature set of the environmental data, generate a first obscured feature from the feature set, transmit the first and second obscured feature sets to the proximity server. The proximity server uses the first obscured feature set and the second obscured feature set to determine whether the first electronic device and the second electronic device are proximate.
    • 公开了用于电子设备之间的接近检测的系统和方法。 一个或多个电子设备将信号发送到接近服务器,接近服务器确定第一电子设备是否可能靠近第二电子设备。 邻近服务器向第一电子设备和第二电子设备发送信号,并且响应于该信号,第一和第二电子设备激活环境传感器,收集至少一个环境数据样本,提取至少一个特征集 的环境数据,从特征集合产生第一隐蔽特征,将第一和第二隐蔽特征集发送到邻近服务器。 接近服务器使用第一遮蔽特征集合和第二遮蔽特征集合来确定第一电子设备和第二电子设备是否接近。
