windows and phone application sans

Hello, there will be two software, one for the computer and the other for the mobile phone. We will write an object or creature(animal, man, women) we want, this creature or object will not be blurred or displayed while watching a movie or surfing the internet. In other words, it will work on the screen instantly and if the selected object appears on the screen as an image, it will censor it and prevent it from appearing.
