password protect or encript SD card

user753,

I would think that the cheapest and easiest thing to do would be to buy a spare 16 or 32g card, and give your guest the camera with the spare (formatted) card in it.

Disabling the wifi would not stop them from taking your card out and putting it in a card reader.

When they give you your camera back, just format the spare card and start all over again, loaning it out over and over.

Those 16 or 32g cards are not very expensive any more.

Thanks for your reply,

How would putting a different card in the camera stop someone from downloading the images either by usb cord or by wifi in the interval between when I give them the camera and it is returned if they take the camera with them to a different location (which they do) without my supervision?

This seems to be a trust issue. If you cannot trust the individual to follow the rules, don’t lend them the camera.

Also, I’m not understanding the point of all this.  After all, the individual could put their own card in the camera, take images to that, then put the original card back.

Not possible with that camera. With older models, for example my 7D, it is possible to run third-party software to encrypt raw files and then later decrypt them in a computer. You can still view the latest pictures stored in the camera RAM until you power off the camera. Enough about that here in this forum.

Canon created OSK-E3 for 1Ds III, 1D III and 1D IV. With that you could verify pictures and also use encryption. The verification function was cracked but never the encryption. I don't know if you can find the software these days.

user753,

What do you care what they do with their own photos?

If you lend them a camera with a brand new card, and they take some photos and then save them to a computer or upload them to the web, what do you care?

They're not your pictures.
