Systems and methods for electronically leashing a user to a mobile device. A user is authenticated on the mobile device and initial sensor data (e.g., radio signal readings, accelerometer readings, image/video, audio) is collected. Based on a timer or other triggering event, additional sensor data is captured and evaluated. Based on the evaluation of the sensor data, a value representing a likelihood of whether the device remains in possession of the user is determined. Upon determining that this value is less than a threshold, the user is required to reauthenticate on the mobile device to further engage with the device or particular features on the device. |
