I've already lost track of how many spy codes are in images. There are so many ways of burying "metadata" in those formats - it's what they were MADE for - and programs that claim to "strip" it are probably "accidentally" forgetting something.
This looks like one more whack at it - I'm not sure from reading that it is a tremendously NEW thing - I'm not sure how they plan to change, say, a .GIF file (not that that didn't have open-ended spy data storage protocols built in already). Are they doing so?

True, especially not just protecting against steganographic high freq noise , but imparting a color table inefficiency of color pallete to encode guid info and simple checksum.
always be wary of the "optimized color table" of compressed images.
The best solution is to have a tool rerender and image, rotate slightly, recrop slightly, add high contrast checkboard border, and over-mix clumpy white noise blended speckle and then save using your own (not the graphics card library) jpeg or png compression for color table choices.
.... not that I ever have anything to hide or anything.
