US Patent 10397222 Authenticating a limited input device via an authenticated application

A limited input device, such as a camera, is authenticated based on a request received from an authenticated application. The application can request an application server to provide the application with a one-time authorization code. The request includes the device identifier associated with the camera. The server stores an association between the one-time authorization code and the device identifier of the camera, and provides the application with the one-time authorization code. The application provides the camera with the one-time authorization code. The camera transmits a request for an access token to the server, the request for the access token including the one-time authorization code and the device identifier associated with the camera. The server verifies the device identifier associated with the camera with that associated with the one-time authorization code, and upon a positive verification authenticates the camera by providing the camera with the access token.
