Original Data Security Kit OSK-E3

Hi

Not an fan of CANON or NIKON, but just read that their is a new application "Original Data Security Kit OSK-E3" for Canon professional EOS system "Verification Kit DVK-E2, the Original Data Security Kit OSK-E3 can detect whether an image has been changed since it was captured by the camera. In addition to data verification, Original Data Security Kit OSK-E3 supports image encryption for protection of critical images." from http://www.dpreview.com/news/0702/07022207eos1dmarkiiiaccs.asp

I wonder if we will see a similar application as it looks an interesting feature.

What if you adjust contrast or exposure? This may be useful for legal imaging but or ordinary users like myself it would be a waste of time.

Not being sarcy, but how do envisage it helping your photography?
