Abstract
A handheld device 300 generates a verification image to indicate that the device is operating in a secure domain. The verification image is generated in dependence upon secure data stored within a secure region 324 of a memory 310 and user input data captured from a user input device 314, 316, 320. The secure data may be data defining a three-dimensional object. The user image data may be captured from accelerometers 314 defining a viewpoint of the secret three-dimensional object.
