Abstract

The approaches presented in the literature are not suitable for detection of children sexual grooming, because the proposals are usually limited to the identification of stages of communication between the predator and the victim. These approaches are inefficient due to the use of a unified profile to identify a sexual grooming stage. Our proposal takes into account the identification of the communication’s stage applying detached profiles, one for the victim and another for the predator. This approach, based on a stochastic technique (i.e. HMM), aims at the individual modeling of each profile to enhance the detection hit rate. The experiments achieved promising identification rates with results closer to 91%.
