Abstract

A system and method for providing a secure user interface in a shared resource environment. Various aspects of the present invention may comprise establishing a first wireless communication link between a first system and a user interface system. A first wireless communication port may, for example, establish such a wireless communication link. A first secure communication pathway may be established between the first system and the user interface system. A first secure communication module may, for example, establish such a secure communication pathway. A second wireless communication link may be established between a second system and the user interface system. A second wireless communication port may, for example, establish such a wireless communication link. A second communication pathway between the second system and the user interface system may be established. A second communication module may, for example, establish such a communication pathway.
