Abstract: A multi-factor user authentication framework using asymmetric key includes a host device, a user agent, a gesture system, and an authentication system. The multiple factors include a user credential as well as a user gesture that indicates that the user is present. The user interacts with the user agent via the host device in order to obtain access to something for which user authentication is needed. The authentication system maintains the user credentials, which are provided to authenticate the user in response to the authentication system determining that the user is present (which can be determined in different manners, such as using a personal identification number (PIN), biometric information regarding the user, geographic location of the gesture system, etc.). The user agent, gesture system, and authentication system can be implemented on the same device (e.g., the host device), or alternatively implemented across one or more different devices.
