Last time this type of detection software was mooted, for child sex abuse images, it used small squares of the image against a known model of such images, which meant sending it off to a server via background scanning.

I guess this could use skin, nipple, and genital detection using a similar model. Which sounds shit, prone to false positives, and easy to circumvent.

Would it upload images for manual checking it wasn’t sure of? That was how the pedo scanner would work.
