Abstract: The techniques disclosed herein may include receiving proximity messages during a first time period via a wireless personal area network. Each proximity message may include a proximity identifier calculated using a unique identifier for a proximate electronic device. In addition, the techniques may include retrieving, from a database, a set of device identifiers corresponding to devices in the first electronic device's contact list. The techniques may include for each message: determining whether the proximity identifier of the proximate electronic device matches a device identifier, thereby determining matching proximity messages. Moreover, the techniques may include generating an event score for the first time period based on the matching proximity messages, the event score having a probability that an event has occurred between the first electronic device another device. Also, the techniques may include determining whether an event has occurred by comparing the event score to an event threshold.
