  • Patent number: 7694328
    Abstract: An innovative security solution which separates a client into a Protected Context, which is the real files and resources of the client, and an Isolated Context, which is a restricted execution environment which makes use of virtualized resources to execute applications and modify content in the Isolated Context, without allowing explicit access to the resources in the Protected Context. The solution further consolidates user interfaces to allow users to seamlessly work with content in both contexts, and provide a visual indication of which display windows are rendered from content executed in the Isolated Context.

  • Publication number: 20070174246
    Abstract: A method includes receiving an event indicating an action associated with a first file has been performed by a user using a first client. The action is unrelated to transmitting the first file to another client. The method also includes automatically extracting content from the first file in response to the event using the first client and generating metadata to associate with the content, and transmitting, using the first client, the content and the metadata to a peer client if the peer client and the first client are currently operating and visible to each other on a network. The timing of the transmission is determined automatically after the event is received.

  • Publication number: 20060179441
    Abstract: A system and method provide access to a target object associated with a desired functionality. This is accomplished by creating an instance of a pre-existing object, replacing one or more functions of a table shared by all objects of the object's class, and triggering a call that ultimately causes the replacement functions to be called to allow access to the target object. The system includes software portions for enabling the method.
