I’ve heard of something similar but rather than sending a suspicious QR-code looking information-image, the information can be encoded into a real picture (PNG for example) by adding the grayscale values of all the pixels in the “QR code-ish square” to the brightness (or r,g,b values) of the pixels of a real picture. This way the image being passed doesn’t look suspicious and the receiver has to have a unaltered/original version of the same picture to get the information out. They just subtract the brightness values of each corresponding pixel for example and are left with an image like what you’re using. You can also limit the information per pixel so that it doesn’t change the brightness more that 16 points for example so that the altered picture seems normal. There are even algorithms that more intelligently select which pixels to edit so as not to change the way the picture looks and raise suspicion but I forget how that works.

it’s interesting but this encryption is very very elementary and wouldn’t really be of any value just because the seed is an integer it is super susceptible to brute force attacks
