Abstract:
1. A method comprising: determining a first geo-location history of a wireless device based on a signal received from the wireless device, the signal indicating a device identifier associated with the wireless device and a first geo-location associated with the device identifier, the first geo-location corresponding to a previous point in time; sending an authentication challenge to the wireless device, the authentication challenge comprising a question about a second geo-location history of a user of the wireless device; receiving a response to the authentication challenge, wherein the response is provided by the user and specifies a second geo-location; and determining whether the user is successfully authenticated based on a comparison of the first geo-location history of the wireless device with the second geo-location history of the user, wherein determining whether the user is successfully authenticated is further based on a distance between the first geo-location and the second geo-location.
