Abstract: A system and method is provided for sharing mobile device location information. The method includes receiving signals by a mobile device and determining by the mobile device a first location of the mobile device at a first time based on the signals received by the mobile device. Time data is accessed by the mobile device and the mobile device determines based on the time data that the first time is in a first time window. The first location is transmitted to a particular user device at least responsive to the first time being in the first time window. The mobile device determines a second location of the mobile device at a second time based on the signals received by the mobile device. A first error is applied to the second location at least responsive to the determining of the second location at the second time, and the second location is transmitted including the first error to the particular user device.

Abstract: A location anomaly for a mobile device can be detected using non-location information from the mobile device. The non-location information does not include data from a location based device, such as a GPS. A probabilistic model is created using historical non-location information accumulated from the mobile device. Current non-location data is compared with the probabilistic model to determine a probability associated with the current non-location information. If the probability is less than a predetermined or configurable threshold, a location anomaly is detected. A notification of the location anomaly may be displayed and/or transmitted in response to detecting the location anomaly.
