Child and adolescent sexual abuse on the internet, Authorship attribution, Stylometry, Pedophilia, Police investigationAbstract
Objectives: Identify the current state of the art of scientific research in the field of authorship attribution applied to investigations of sexual crimes against children and adolescents over the Internet involving written material. Propose a methodology for using authorship attribution to identify suspected authors of texts with content that encourages child and adolescent sexual abuse.Methodology: This is a qualitative research that uses the Systematic Review of Literature to identify works that deal with the techniques of authorship attribution in order to seek scientific evidence of its application to problems similar to the one addressed in the present study.
Results: The current state of the art of scientific research that relates the use of authorship attribution techniques to texts on the internet that encourage the practice of sexual abuse of children and adolescents is presented and, from this, a methodology is proposed to identification of authors of texts with those characteristics.
Conclusions: It is concluded that there is not an abundance of scientific research on this topic, which suggests that it is an open field for further studies. It is also concluded that it is fully possible to apply the techniques of authorship attribution in the identification of the probable authors of texts that aim to guide and encourage the practice of child and adolescent sexual abuse, which is explained by the proposed methodology.
