Secure Surveilance Camera
Have you watched impossible heists on Discovery?
In it a surveillance camera is replaced by one that transmits a fake image by the intruders and the security officers have no clue that they are staring at a fake image. Another trick is to physically hang a picture in front of the camera to fool the security officers.
If the camera has the ability to digitally sign the photo using cryptographic keys embedded within the camera, then a replaced camera can be instantly detected and an alarm generated.
The focusing apparatus of the camera can determine the distance of the object and generate a warning if most of the camera is covered by an image at close distance.
