Abstract: Systems and techniques are described for facilitating sharing information. Some embodiments can receive a set of data items that is to be analyzed for sharing, analyze the set of data items based on a first set of criteria to obtain a subset of the set of data items that is a likely candidate for sharing, and present the subset of the set of data items to a first user. Additionally, some embodiments can receive a set of users that is to be analyzed for sharing information, analyze the set of users based on a second set of criteria to obtain a subset of the set of users with whom the information is likely to be shared, and present the subset of the set of users to the first user.

Abstract: A first device periodically transmits a first audio signal that encodes a first code over an audio channel that is shared between the first device and a second device, and the second device periodically transmits a second audio signal that encodes a second code over the audio channel. When the first device receives the second audio signal over the audio channel, the first device extracts the second code from the second audio signal and sends the second code to a server. When the second device receives the first audio signal over the audio channel, the second device extracts the first code from the first audio signal and sends the first code to the server. If the server receives the first code from the second device and/or the second code from the first device, the server can conclude that the first device is in proximity to the second device.

Abstract translation: 第一设备周期性地发送通过在第一设备和第二设备之间共享的音频信道上对第一代码进行编码的第一音频信号，并且第二设备周期性地发送通过音频通道对第二代码进行编码的第二音频信号。 当第一设备通过音频通道接收第二音频信号时，第一设备从第二音频信号中提取第二代码，并将第二代码发送到服务器。 当第二设备通过音频通道接收第一音频信号时，第二设备从第一音频信号中提取第一代码并将第一代码发送到服务器。 如果服务器从第二设备接收到第一代码和/或从第一设备接收第二代码，则服务器可以断定第一设备在第二设备附近。
