Abstract
User interaction with multiple domains is facilitated while preventing cross-domain transfer of data from those domains. A compositioning domain facilitates this interaction in a secure manner in which cross-domain transfer of data is prevented. This includes obtaining pixel information from the domains via one or more read-only communication paths, providing a user interface to the user, which includes providing a display buffer including at least some of the pixel information obtained from each domain of the domains for display to the user, and maintaining an in-focus domain state. The in-focus domain state indicates which domain of the domains is currently in-focus. User input from the user based on the user interface is provided by a user input handler directly to the currently in-focus domain indicated by the in-focus domain state absent transfer of the user input to the compositioning domain.
