Abstract
Techniques are described for authentication using sound-based monitor detection. In some implementations, the sound (e.g., ultrasound) generated by a monitor is used to detect its presence in the vicinity of a (e.g., portable) computing device that is being used to capture image(s) to be provided to an image-based authentication system. While the computing device is being used to capture image(s) to be provided to the image-based authentication system, the sound data in proximity to the computing device can be captured and analyzed (e.g., using machine learning or other techniques) to determine whether the sound data exhibits a particular pattern and/or characteristics (e.g., signature) that indicates the presence of a monitor in proximity to the computing device. The presence (or absence) of a monitor can be used in determining whether to authenticate the user.
