Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a biometric authentication system having anti-spoofing capabilities. A biometric authentication system can use a vibrating component of a mobile device to determine whether the mobile device is oriented in a self-portrait orientation or in an orientation other than the self-portrait orientation based on a vibration response signal received from sensors on the mobile device. In response to determining that the mobile device is oriented in an orientation other than the self-portrait orientation, the biometric authentication system can prevent access attempts to one or more secure systems.
