Abstract
The invention relates to a method for displaying information on a display device (D, D) of a terminal, particularly a mobile terminal, wherein the terminal contains a microprocessor unit in which a normal runtime environment (NZ) and a protected runtime environment (TZ) are implemented, wherein display data (DD, DD, DD', TDD) can be provided for reproduction on the display device (D, D) by means of the normal runtime environment (NZ) and the protected runtime environment (TZ). In this case, at least some display data (DD) provided by means of the normal runtime environment (NZ) are transferred to the protected runtime environment (TZ), which checks whether the transferred display data (DD) satisfy one or more security criteria, wherein if they do not satisfy at least one security criterion then the display data (DD) are rejected or are altered such that they can be distinguished from display data (TDD) provided by means of the protected runtime environment (TZ) when they are next reproduced on the display device (D, D).
