TRUSTED COMPUTING PLATFORM FOR RESTRICTING USE OF DATA

摘要

A client/server system has a client platform (1001) adapted to provide restricted use of data provided by a serve (1109). The client platform (1001) comprises a display (1005), secure communications means, and a memory containing image receiving code (1004) for receiving data from a server (1109) by the secure communication means and for display of such data. The client platform (1001) is adapted such that the data received from a server (1109) is used for display of the data and not for an unauthorised purpose. A server (1109) adapted to provide data to a client platform for restricted use by the client platform comprises a memory containing image sending code (1103) for providing an image of data executed on the server (1109), and secure communications means for secure communication of images of data to a client platform (1001). The server (1109) is adapted to determine that a client platform (1001) is adapted to ensure restricted use of the data before it is sent by the image sending code (1103).
