Abstract
The application provides a method for attack detection in biometric authentication. The method may be implemented by a mobile terminal device, and comprises: obtaining sensor data of the mobile terminal device, wherein the sensor data is collected when the mobile terminal device performs biometric authentication, and the sensor data comprises acceleration sensor data of the mobile terminal device indicating accelerations of the mobile terminal device in x, y, and z axes of a three-dimensional space, and/or gyroscope data of the mobile terminal device indicating angular velocities in the x, y, and z axes of the three-dimensional space; and inputting the sensor data into an attack determination model to determine whether an attack occurs in the biometric authentication, wherein the attack determination model is trained by using sensor training data obtained based on sensor data of the mobile terminal device collected when the mobile terminal device performed biometric authentication historically.
