If you can slightly distort an image to make NN produce any classification you want that opens many interesting options for steganography. Funniest application

If you can slightly distort an image to make NN produce any classification you want that opens many interesting options for steganography. Funniest application would be distorting individual characters of the printed text so that OCR engine and human would "see" two totally different but meaningful messages. There's likely not enough complexity in the OCR NN to do that, but who knows.
