Previously, when people needed anonymity in photos, you have to pixellate their faces. Now, with Kiteman's Unique Pixellation Indication Device (K.U.P.I.D.) you don't need to.
Step 1: Background.
Computer-based pixellation lowers the resolution of digital images, merging details and averaging tonal data to render individual features unrecognisable.
But haven't you ever suspected that some clever bugger somewhere could undo it? We've all seen those spy films where they keep enhancing passport-sized photos until they can see the faces of people reflected in the subject's pupils...
Maybe I'm just being paranoid, but K.U.P.I.D. is a guaranteed barrier to such processes.
