Abstract: An illustrative geolocation authentication system designates a movement feasibility corroboration factor as a location corroboration factor for the geolocation authentication system to authenticate geolocations of mobile devices. Based on the designating of the movement feasibility corroboration factor, the geolocation authentication system determines a first reported geolocation of a mobile device associated with a first time and a second reported geolocation of the mobile device associated with a second time. Given that the mobile device is located at a true geolocation at the second time, the geolocation authentication system then determines, based on the first and second reported geolocations of the mobile device, a feasibility metric indicative of a likelihood that the second reported geolocation of the mobile device is the true geolocation at the second time. Corresponding methods and systems are also disclosed.

Abstract: An exemplary geolocation authentication system receives user input representative of customized authentication settings that designate a location corroboration factor from a plurality of location corroboration factors that correspond to independent ways of determining geolocations of mobile devices. The system receives, from a mobile device located at a true geolocation, a reported geolocation of the mobile device. Then, in response to the receiving of the reported geolocation, the system accesses a datapoint that characterizes a correlation between the reported geolocation of the mobile device and the true geolocation of the mobile device. The datapoint characterizes the correlation based on the location corroboration factor designated by the customized authentication settings. The system further determines, based on the datapoint, a custom confidence metric representative of a likelihood that the reported geolocation is the true geolocation. Corresponding methods and systems are also disclosed.
