Porn detection & cleaning tools have algorithms for picking up readable documents and then checking them for porn content. The software begins by comparing keyphrases against a repository of phrases of interest to the user. These include adult based content to do with homosexuality and adult terminology; coarse language such as racism related items, articles about violence, hate or any such unacceptable items; detection of rights abuse; all of these can be detected and then displayed as the obtained scan results in the result screens. If any suspicious items are found they can be marked for hands-on checks by the software operator and the decision made about what to do with the individual files in the necessary way.

Image file detection should always be done when using software to test your system files , to uncover any items that must be deleted. Inappropriate online material often takes image form, and some of the time viewers of this type of content keep copies for themselves on the HDD so they can be viewed again. So it's essential for porn detectors to segregate suspect and normal images, and show these in the most meaningful way for the operator of the software to analyze. Categorizing the files can involve testing of the files to ascertain whether any porn material exists. One suspicious factor is checking the presence of skin tones present in the image. But discovering skin pigment isn't the main factor because family photos sometimes do have similar color ranges to skin. Therefore if skin coloring is present in the image several testing cycles are then used to analyze them further, to pull out the adult images from standard ones; like image feature isolation, background isolation, etc. Files detected are then organized and tabulated for review.

Washing a dirty computer having a big set of offending data files, may be done by one of the many special purpose detection executables which are now available from the net.
