Impenetrable captcha

    Now captcha always and everywhere, and the competition between robot generators and recognition degenerator robots has led to the fact that it is often difficult for a person to read captcha.

    It can go along the path of crosswords / children's blocks - drawing a house - the answer is “a word of three letters” - and the database for this glyph has a dozen correct options “house”, “house”, “house”, “building”, “her- with windows "?

    PS - yes, it is necessary to impose very simple noise dynamically on the picture. - so that the bot could not compare the pictures themselves. And to recognize non-font images by a neural network - you get sick.
