Patent ID: 8911507

Claim:
A computer-implemented method for mitigating mobile device loss, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: identifying historical data specifying a plurality of location-time pairs for a mobile computing device, wherein each location-time pair specifies a past location for the mobile computing device and a time corresponding to the past location; identifying a current location-time pair for the mobile computing device based on a current location of the mobile computing device and a current time; determining, using a machine-learning technique trained using the plurality of location-time pairs, that the current location-time pair deviates from an expected location-time pair due to a statistical likelihood of the mobile computing device being at the current location at the current time falling below a predetermined threshold; performing a security measure on the mobile computing device in response to determining that the current location-time pair deviates from the expected location-time pair, wherein performing the security measure on the mobile computing device comprises presenting a challenge comprising a communication disguised as originating from a human contact to verify that an authorized user of the mobile computing device is in possession of the mobile computing device and to conceal from a potential thief that the potential thief is being tested by the challenge.
