Abstract
There are provided systems and methods for gesture and motion detection using a device radar component for user authentication. A user's device may include a miniaturized radar component that is capable of detecting objects, gestures, and motions within an area around the device in a three-dimensional manner, such as a user hand, arm, or other body part that may perform a motion or gesture. A service provider, application, or another user may generate and transmit an authentication request to the user that may include some query for the user to perform one or more actions or gestures. The user may perform the actions or gestures in response to the query, which may be detected by the radar component and processed to determine whether to authenticate the user. In some embodiments, the gesture may be performed using a virtual projection or real objects in the environment nearby the device.
