Patent attributes
This disclosure describes techniques that permit a user of a client device to authenticate their identity to a service provider using location-based telemetry data associated with the client device that is captured unobtrusively by a service provider over a predetermined time interval. More specifically, a Location-based identity authentication (LIA) system is described that is configured to develop authentication challenges that are based on the location-based telemetry data, such as location data, transaction data, calendar data, and event data. In one example, a client device may transmit an authentication request that relates to a set of service features available to a user identity. The LIA system may transmit a subset of the authentication challenges to the client device to authenticate the user identity. The LIA system may further receive to the subset of authentication challenges, and further, verify the user identity based at least in part on the number of correct responses.
