This paper proposes on the blocking method of Internet harmful sex sites by accoustic signal processing. Pre-existing methods mainly focused on directory-based blocking and words-based blocking. But these methods are not completely blocked the Internet harmful sites. Therefore, we propose the content-based blocking method which compose of the image-based blocking and the accoustic-based blocking. In this paper, we mainly deal with the accoustic -based blocking method. Finally, the effectiveness of this system is demonstrated by several experiments.

This paper proposes on the acoustic signal processing blocking method of Internet pornographicl sites by calculating correlation values between prototype acoustic signals and input acoustic signals. Pre-existing blocking methods mainly focused on directory-based bled(fin and pornographic related words-based blocking. But these methods are not completely blocked the Internet harmful pornographicl sites by several situations. For this, this paper proposes the content-based blocking method which composes of the image-based blocking and the acoustic-based blocking. This paper, mainly, deals with the acoustic -based blocking method. Finally, the effectiveness of this system is demonstrated by several experiments.
