Abstract: A system is described for authenticating a user on a client device using the user's mobile device and utilizing the audio channel. An authentication server receives a request from the client to initiate a session for the user, creates the session, and sends a session token back to the client along with a request for authentication. The client broadcasts an audio transmission containing the token to the mobile device over an audio channel using data-over-sound transmission. The mobile device receives the transmission via a microphone, obtains the token and the server identity from the transmission, and sends user credentials that are stored on the mobile device along with the token identifying the session directly to the authentication server. The server verifies the received credentials, confirms the token, and logs the user into the session.

Abstract: Hybrid application delivery is described which utilizes both remote access and downloading of content over the network. When a user requests an application that is not locally available, a remoting session is first established to allow the user to begin using the application. While the user is accessing the remote session, a process is initiated to download the content of the application to the end user's device. This process may execute in the background while the user continues to use the application over the remote session. Once the process of downloading the content of the application is complete and the application is installed, a local session of the application is started and the user may switch to the local session. The system also synchronizes changes to user data made on the server during the remoting session with the end user's computing device.
