What's that steganography?
(too lazy to look it up)
TL;DR: Steganography is the practice of hiding secret messages in otherwise non-secret mediums.

I hadn't heard of the name either, but here's something I found that might help: Steganography: How to Hide Secret Data Inside an Image or Audio File in Seconds « Null Byte :: WonderHowTo

Watermarked or not, every one of the better photos that I've posted to the Internet in the last 19 years has been stolen - multiple times.

Great, 5-star images that are visible on the Internet WILL BE stolen. If your images posted to the Internet are not being stolen, it's only because they are not considered good enough to steal.

Unfortunately, stolen images are a sign that your images are outstanding. Sick, but true...

Your post took 4 times the effort of googling. I don't want to spoil it...

Did you try to get a compensation for these stolen photos? Or just take them down?

I came across this article: Google shows how easy it is for software to remove watermarks from photos - The Verge that I thought some around here might be interested in, particularly if you're watermarking your images for protection.

There's a short video that shows the theory behind their paper, and there are links to the actual document if you are one of those boffin types that can do math with the alphabet.

Given the pace of AI these days I'm not surprised at this. Even using the content-aware filter in Photoshop can achieve reasonable results. But am I right in saying that in order to protect the photographer's copyright, the EXIF data in a photograph can NEVER be removed?

EXIF and XMP data can easily be removed. In Photoshop for instance the Save for Web option with the Metadata set to None will do this.

Legitimate reasons for doing this may include reducing file size, removing sensitive information etc.

I am always under the impression that folks who are interested in "burgling" tend to head for places which look easier rather than the homes with 50 million dollar security systems. Obviously watermarks can be removed, but it is an extra step and I think would deter, even if it doesn't totally prevent, thievery.

Simplisticly, steganography is a way of encrypting data into an image in a way that is impossible to detect without the encryption key.

Watermarks ruin the photo. I've had my photographs stolen a few times by newspapers and such. Honesly I dont care much as its been small reproductions. People use my photos all the time in non commercial ways which is fine by me. Sharing images is such a great thing to be able to do.

I hate Pinterest though. My photos are on lots of boards and come up in searches on the topics but I cant see them because you have to have an account ! I'm blocked from viewing my own photos but they still show up in searches to drive clicks to Pinterest. Aarrgh.

Decent publishers quickly find me as the source of the photo but generally the pay is so low that I rarely go through the hassle of getting paid. I guess I've could have bought a lens or two over the years.

Thanks! Yes, I appreciate that, but what I really meant was, can the exif data be removed from a jpeg once it's been published online?

Yes very easily. In fact many web services strip the exif before sending it to the users browser. Anyone downloading your image can also strip exif by simply opening it and re-saving it without exif data. This can also be automated or scripted.

The problem is, the watermark with every passing year is becoming less and less like a good security system and more like a sign on the door saying "don't steal our stuff".

Many of the gallery sites like 500px and and 1x prevent downloading of images, but that doesn't stop anyone from screenshot-pasting and saving at low quality. I have not seen a lot of my work get appropriated as I'm not that great, but I did have one photo make some pretty heavy rounds on social media with the watermark removed by just cropping down the photo. It bothered me a bit at first as people generating traffic revenue off ill gotten material is frustrating, but I doubt it had any real financial significance.

No need for screenshots. All images can be downloaded directly by standard browser features. Its just 4 or 5 clicks instead of 2.

Obviously any content which your browser downloads anyway to display is easy to save as a file.

But I agree with Rondec that the most efficiency have any means which make all this a little effort. People are lazy.
It is not a unique 50 million painting we talk about, which would be worth substantial effort.
