The disclosed embodiments relate to a system that authenticates and/or identifies a user of an electronic device based on passive factors, which do not require conscious user actions. During operation of the system, in response to detecting a trigger event, the system collects sensor data from one or more sensors in the electronic device. Next, the system extracts a feature vector from the sensor data. The system then analyzes the feature vector to authenticate and/or identify the user, wherein the feature vector is analyzed using a model trained with sensor data previously obtained from the electronic device while the user was operating the electronic device.

Identifying and authenticating users based on passive factors determined from sensor data

The disclosed embodiments provide a system that authenticates a user of an unattended device. In response to sensing a presence of the user in proximity to the unattended device, the system makes a call from the unattended device to an authentication service to authenticate the user. In response to the call, the authentication service authenticates the user based on recently collected sensor data, which was obtained from one or more sensors in a portable electronic device belonging to the user. If authentication succeeds, the system allows the user to proceed with an interaction with the unattended device.
