Re: Digital camera a security risk?
It's not a concern for me in regard to any situation I've been in. If it were a concern, I would just strip the EXIF data.
These are possibilities to be aware of. It could be valuable information for bloggers in repressive countries, for example. |

| I would say that TO ME this is not a very big deal except for two things...
1. The thumbnail issue. IF (and this is a big if because I haven't ran across it yet) you have a camera that takes big thumbnails that can be enlarged, then it is bad because if you crop a picture or cover something in a picture someone could possibly still see the original image. I think this is a valid concern from a security perspective as I think has been shown.
However most cameras take very small thumbnails and as such those thumbnails get very very pixilated when enlarged. So much so that there is no detail what so ever. But still it may be enough to show information or detail that you may not wish to show.
2. There seems to be a lot of *unknown* data in there that no one, so far, has been able to definitively show what it is. While I don't think that any of that code is important you never know. I don't like unknown quantities 
However I feel that if you could read that code it would probably image or camera information.
Now with regards to #1 above, if a program like PhotoShop or similar could reconstruct the original image in original size before any manipulation of the image was done, from that code or thumbnail then that could be a big problem. But from my informal tests with other image software I don't see any way to do that. |
