No matter how you design the camera the system is not secure. The entire concept is, in fact, impossible to implement. All I need to do is take a picture, retouch it however I want, then project it back into the camera using a high-quality lens system.
Yes in principle, you control the camera's environment so you control all the incident light, but other replies suggest it would be hard in practice.
The real question is this: would it be more or less effort than obtaining the master key via a bribery/blackmail/infiltration/intimidation/ninja attack against cannon ?
