A methodology for profiling paraphilic interest in Child Sexual Exploitation Material users on peer-to-peer networks

This paper describes the development of a novel methodology for profiling paraphilic interest in the search behaviour of users of online peer-to-peer (P2P) networks - a major vector for the exchange of Child Sexual Exploitation Material (CSEM). The profiling methodology focuses on problematic paraphilic interests, involving illegal or non-consensual activities associated with the sexual victimisation of children. This work extends an earlier typal analysis carried out by Hammond et al. (2009. An examination of problematic paraphilic use of peer to peer facilities. In Advances in the analysis of online paedophile activity (pp. 65-73). Paris: MAPAP Project) in which a distinct problematic paraphilic typology was uncovered in the search behaviours of P2P users. The methodology described focuses on the subsequent development of a latent class model that underpins the operation of the profiling application. The composite profiling process is described. Finally, we discuss the prospective applications of this profiling process and the implications of our methodological design. We identify a series of recommendations for future research and for the design of profiling and risk appraisal processes with application to online CSEM offending behaviour.
