Abstract (en)
[origin: EP2747071A1] The method involves drawing a graphics (32) that is to be represented on a monitor (30), by client applications (11, 12) in a client specific region (22) i.e. overlay buffer, of a memory e.g. frame buffer, of a graphics circuit. A tamper-resistant identity indicator (31) that belongs to the client applications, is drawn in a memory area (21) outside the client specific region. The client specific region is displayed on the monitor by using a display controller (20). The indicator from the memory area is simultaneously displayed on the monitor using an overlay functionality of the controller. Independent claims are also included for the following: (1) a computer system (2) a computer program product comprising instructions for performing a method for displaying a tamper-resistant identity indicator on a monitor.
