yes to me it read like it was manipulating metadata somehow, not the images themselves, but the article directly contradicts that. and that would be useless as soon as someone saves it as a flat image file or screenshots and cuts it out. i’m assuming for this tool to work it needs to be changing the image directly through some sort of watermark-like system.
this seems interesting, but how does it actually work? “invisible changes to the pixels” is vague and the article does not go into more detail of the actual method of manipulation or the ways that an invisible input can affect visible changes in the output.
