Abstract
Implementations relate to user authentication and spoof detection for a device using a fingerprint sensor and additional device sensors. In some implementations, a computer-implemented method includes analyzing a fingerprint image from a fingerprint sensor of a device, to determine fingerprint detection score(s). If these scores meet fingerprint validity thresholds by greater than a respective particular range, a positive authentication indication is provided. Respective sensor data is obtained from additional sensors of the device, such as an inertial measurement unit, ambient light sensor, proximity sensor, touchscreen, etc. If one or more fingerprint detection scores meet their fingerprint validity thresholds within the respective particular range, respective context scores are determined for the sensor data of each additional sensor. If the context scores meet respective context validity thresholds, the positive authentication indication is provided, or otherwise a negative authentication indication is provided.
