Re: Where do you go to authenticate Canon photos?

Call Canon - there's a data verification kit for these kind of things. Unfortunately the format has been cracked anyhow. Exiftool was a great suggestion.
Besides that, something every photographer knows about - hot pixels are unique to each sensor but change slowly over time. You can authenticate pictures to a camera if you can create samples from that camera.

The ideas about order are good too, a simple progression is self-heating as you use it increases the variance of the noise. You can track sensor temperature, battery temperature and battery voltage as well.

Theoretically all of these could be faked though, with a sophisticated enough attacker. They would have to be knowledgeable enough to research like 'script kiddies' do though.
