#24I am not exactly buying the premise here, if you train a CNN on useful semantic categories then the representations they generate will be semantically meaningful (so the error shown in blog wouldn’t occur). I dislike the general idea of iCloud having back doors but I don’t think the criticism in this blog is entirely valid. Edit: it was pointed out apple doesn’t have semantically meaningful classifier so the blog pos…

#26I've also implemented perceptual hashing algorithms for use in the real world. Article is correct, there really is no way to eliminate false positives while still catching minor changes (say, resizing, cropping, or watermarking).

these people also have no incentive to find you innocent for innocent photos. If they err on the side of false-negative, they might find themselves at the wrong end of a criminal search ("why didn't you catch this"), but if they false-positive they at worse ruin a random person's life.
