Reliability of data reports can be determined by a device that receives a number of reports from different sources. One method includes: receiving data reports from devices. The data reports are associated with an occurrence of an event. The method also includes determining reliability data representing reliability of the data reports. The reliability can be determined based on one or more different defined characteristics such as the location at which a data report was generated relative to the location of the event, whether the data report was the most recently-received data report and/or the number of data reports reporting that an event is ongoing relative to the number of data reports reporting that the event is no longer ongoing. The method can also include determining whether a data report includes information indicative of a false positive report or a false negative report.
