Abstract

A device for providing a security breach indicative audio alert. The device includes: a security monitor adapted to detect a security breach in device and a loudspeaker, the device wherein including a secure audio alert generating hardware, adapted to participate, in response to the detection of the security breach, in a generation of a security breach indicative audio alert. The secure audio alert generating hardware is connected to an audio mixer that is adapted to mix the security breach indicative audio alert signal with audio signals generated by a software controlled audio source to provide a mixed signal. The audio mixer is further adapted to provide the mixed signal to the loudspeaker that reproduces the mixed signal as sound.

Claims

1. A method for providing a security breach indicative audio alert, the method comprises:

detecting a security breach in a device that comprises a loudspeaker;

responding to the detection of the security breach, by a secure audio alert generating hardware, a security breach indicative audio alert signal;

mixing the security breach indicative audio alert signal with audio signals generated by a software controlled audio source to provide a mixed signal; and

reproducing the mixed signal as sound via the loudspeaker.

2. The method according to claim 1 wherein the generating comprising repetitively generating a security breach indicative audio alert signal.

3. The method according to claim 1 wherein the generating comprises repetitively generating a security breach indicative audio alert signal, for a predefined alert period.

4. The method according to claim 1 wherein the generating comprises randomly altering at least one characteristic of the security breach indicative audio alert signal.

5. The method according to claim 1 wherein the generating comprises dynamically altering at least one characteristic of the security breach indicative audio alert signal.

6. The method according to claim 1 further comprising:

generating, in response to the detection of the security breach, by at least a secure icon generating hardware, a security breach indicative icon; and

overlaying the security breach indicative icon over a background image.

7. The method according to claim 6 wherein the generating comprises replacing a software-generated mouse icon by the security breach indicative icon.

8. The method according to claim 6 wherein the generating comprises:

providing location information representative of a required location of the security breach indicative icon; and

wherein the overlaying comprises overlaying the security breach indicative icon at the required location.

9. The method according to claim 6 wherein the generating comprises retrieving security breach indicative icon image information from one time programmable elements.

10. (canceled)

11. A device for providing a security breach indicative audio alert, the device comprises:

a security monitor adapted to detect a security breach in the device and a loudspeaker;

a secure audio alert generating hardware, adapted to participate, in response to the detection of the security breach, in a generation of a security breach indicative audio alert; and

an audio mixer, coupled to the secure audio alert generating hardware, wherein the audio mixer is adapted to mix the security breach indicative audio alert signal with audio signals generated by a software controlled audio source to provide a mixed signal and to provide the mixed signal to the loudspeaker so that is adapted to reproduce the mixed signal as sound.

12. The device according to claim 11 wherein the secure audio alert generating hardware is adapted to repetitively generate a security breach indicative audio alert signal.

13. The device according to claim 11 wherein the secure audio alert generating hardware is adapted to repetitively generate a security breach indicative audio alert signal for a predefined alert period.

14. The device according to claim 11 wherein the secure audio alert generating hardware is adapted to randomly alter at least one characteristic of the security breach indicative audio alert signal.

15. The device according to claim 11 wherein the secure audio alert generating hardware is adapted to repetitively generate a security breach indicative audio alert signal to dynamically alter at least one characteristic of the security breach indicative audio alert signal.

16. The device according to claim 11 wherein the secure audio alert generating hardware is adapted to repetitively generate a security breach indicative audio alert signal.

17. The device according to claim 11 further comprising:

a display, a secure icon generating hardware, and a display image unit;

wherein the secure icon generating hardware is adapted to participate, in response to the detection of the security breach, in a generation of a security breach indicative audio alert;

wherein the secure icon generating hardware is coupled to the display image unit that is adapted to cause the display to display a background image and a security breach indicative audio alert that is overlaid over the background image.

18. The device according to claim 16 wherein the device is adapted to replace a software-generated mouse icon by the security breach indicative audio alert.

19. The device according to claim 16 wherein the secure icon generating hardware is adapted to provide location information representative of a required location of the security breach indicative audio alert;

and wherein the display image unit is adapted to cause the display to overlay the security breach indicative audio alert at the required location.

20. The device according to claim 16 wherein the secure icon generating hardware is adapted to provide predefined location information from one time programmable elements.

21. An information processing apparatus comprising a device of claim 11.
