But image similarity is not the same as face recognition. I just uploaded the photo the author gave to Clearview, and it returned none of the photos Clearview found – just other front-facing flatly-lit mugshots of other people. Of course Google can do this internally (and FAcebook could do it even better) – but the public-facing image search does not do what Clearview purports to do.
