In order to minimize the spread of these kind of photos, this paper proposes a method to prevent smartphones users to take pornographic photo. This paper proposes a built-in camera application that can detect the existence of pornographic aspect in a photo then it can automatically censor the pornographic part in real time. The main approach used in this paper is it recognizes the pornographic part of a photo by using pattern matching method, then it censors those parts automatically. If a smartphone user tries to take a pornographic photo, with this proposed system, then he/she will save a photo including the censors. The key feature of proposed method is its ability to censor only pornographic part of a photo automatically in real time. This proposed method is also implemented in common smartphone. It has been tested to practically run in low resource machine like a smartphone. This paper is designed to overcome the ambiguity of pornographic photo. For example, in some countries the existence of bra can be categorized as a pornographic part of a photo. Meanwhile in other countries, a pornographic part of a photo must contain nipples. The proposed method uses external files as pattern matching templates to find pornographic part in a photo. By using the external files, the proposed method can flexibly adjust its measurement of pornographic part in a photo according to the circumstance that it faces. For example, the proposed method uses different external file to identify pornographic part in a photo taken in West Countries and in East Countries. By using the proposed method, the spread of pornographic photo taken by smartphone can be decreased automatically and flexibly.
