Abstract
A method is disclosed to authenticate a local interface for a network attached projector. The method provides a projector, an information storage medium comprising first information, and a communication link capable of communicating with the projector and with the information storage medium. The method defines access rights for the first information. Upon receiving a request for access to the first information from the projector, the method determines if the requestor has access rights to the first information. If the method determines that the requester has access rights to the first information, then the method provides the first information to the projector. Alternatively, if the method determines that the requestor does not have access rights to the first information, then the method denies access to the first information.
