Snitch's porn detection algorithms have been optimized to analyze an image for key properties normally found in pornographic content. Pornographic material comes in many different varieties, and so the techniques used to identify it must handle these variations. The software must take into account many different factors when assigning a weighting to an image or a video frame capture.
A prime example of this can be seen in the comparison between a 'pokemon porn' style image and a regular image, see figure 1. Immediately a number of factors that distinguish the two types of image are apparent.
When it comes to detecting the differences between cartoon porn and regular porn, all these factors, and many more besides, factor in to applying an accurate suspicion rating for a given image. The algorithms in Snitch products take all these factors into account. Each factor applies a variable weighting to the final calculation. The weighting assigned for a given factor can be either positive or negative, depending on other detected factors.
One might feel that the detection of cartoon porn is of low importance when scanning a computer for porn, given the fact that compared to normal pornography it is hand drawn, the characters are fictitious and any depicted activity is not real, so this type of content must be benign.
However several recent court cases would seem to indicate that some cartoon porn can be considered illegal. This report outlines a case where a man was found to have 'visual representations of child sexual abuse' on his computer after having downloaded porn featuring child characters from the Simpsons. A similar case is discussed here.
Snitch and Snitch Plus use a complicated weighting algorithm that has been adjusted over years of experimentation. The result of these efforts has produced a SkinScan™ engine with superb accuracy, far beyond the capabilities of any competing technology.
