One of the interesting new devices that is optional on the Canon
EOS-1D is a data verification device. The camera can be set to write
a code into the header of the digital file. The image file can then
be read by a device that will verify whether the image has been
changed at all even by one pixel.

What's to keep some software from modifying or deleting the verifiction data?

Ah well. The thought of digital image hackers crossed my mind, but that seemed too silly. Or, God forbid, a digicam virus waiting to infect your camera the minute you connect it to something.
