No? Is there any use for this besides people sharing Child Sexual Abuse imagery without being detected?
- wildzzz 4y agoAl Qaeda was hiding documents inside porn videos they were passing around. I'm guessing if you can find a video host that doesn't transcode the original file, you could publicly post these videos with special keywords for your comrades to discover.

It can make it easier to share state, and be more easily human-identified among other saves. Hiding one thing inside another doesn't necessarily require secrecy as part of the intent.
- daenz 4y agoI see your point, but that's not really a photo inside of another photo. What kind of secret photos do people need to be hiding inside of other photos?
- CogitoCogito 4y agoMaybe people just want to have some fun? Send a secret picture only to their friends? Or maybe they want to send an image while hiding it from a government censor? I'm sure you can come up with more examples if you use your imagination. Besides complaining about the potential use for child pornography is bizarre. If someone wanted to secretly send child porn to someone else, they could just encrypt it. It would be far more effective than this image packing method.

- CogitoCogito 4y agoNo and I'm a bit unclear how you inferred that. I am, however, making the claim that embedded images similar to the blog post are much easier to discover than it is to break encryption. Does that clarify things for you?
- josefx 4y agoA reporter might want to hide images that could be considered regime critical if they might be searched. Lots of nice pictures of healthy patriotic people, no suffering and starving people, empty shelves or grass stealing beggars to see. Or without leaving the country you might want to hide pictures of animal abuse if you took them without permission from the owner, in some places documenting animal abuse is even more illegal than committing it. Look at all those funny cat pictures, no cows rotting in their own shit to see officer.
- daenz 4y agoYou could do that by hiding a document in any other document with existing tools. A picture in a picture is pretty specific to the format of most online media consumption.
- avestura 4y agoThe fact that "Child Sexual Abuse imagery" is the only use case your brain could think of for Steganography says a lot about you. I wish I could report and block you a thousand times.
- bingu 4y agoConsidering how a technology could be mis-used shouldn't be frowned upon.
- daenz 4y agoReport me for what? Being realistic about what a "hide a picture in a picture" technology is probably going to be used for? What an extreme of overreaction. That's like inventing a "remote roadside detonation device" and claiming it will only be used for parades to activate confetti payloads. It's naive.
- josefx 4y agoAn invisible way to hide a signature comes to mind. Until the ownership comes into question no one will be aware that the image itself contains all proof needed. You could do something like Eurion and hide a pattern that only copiers can identify. Or do the same as color printers and encode hardware and user information as a pattern. DOOM 2016 hid satanic images in its sound files instead of other images, of course that was only an easter egg and not really useful outside of confirming that computer games are evil.
