You did a nice job of honing on the real issue here, for any real practical attempt to hide something in an image.
If an image comes under the slightest scrutiny at all, it's not to hard for someone who works with images a lot to tell if the file size is unusually
large for the image.
Take the ATS uploading file limit for example, it's 500k, so even ATS knows there are a lot of images smaller than 500k Most of my digital camera
images are in the ballpark of 400k. I could hide 100k in the image and make it 25% bigger, and that would probably avoid further scrutiny. But, 100k
isn't a lot. So unless you only have a handful of very small things you want to secure, hiding stuff in images doesn't seem very practical to me. I
like the video idea, that's a lot more practical, if you have more to secure, but it still has limits. Still one of the things I like about it is that
it's a little harder to pin down the exact size a particular video should be, than to pin down the size an image should be. So in addition to the
video being larger to begin with, you may not be limited to a 25% file size increase, you may be able to increase the file size by significantly more
than that and not arouse suspicion.
If you Google the terns security encryption faq, there's a document that talks about creating a virtual drive with VM workstation for security
purposes, in conjunction with another program hat involves some kind of encryption. I haven't tried it yet, but I've been thinking about it with all
the hackers and thieves out there. It sounds like it might take some effort to set up, but once you do, it's probably a lot easier to use than
reprocessing a bunch of images or videos. The author claims it's not easily detected, but I'm a little skeptical of that claim.
Actually, I'm not a security expert. For all I know that security and encryption FAQ was written by the NSA as a guide they hope terrorists will use
so it will be easy for them to crack!
But even if that's the case, I am only trying to keep my stuff secure from the hackers and thieves, as
long as it's good enough for that, the NSA issue doesn't concern me.
