  This paper presents a study on the advancement of computational models for
the analysis of illicit activities. Computational models are being adapted to
address a number of social problems since the development of computers.
Computational model are divided into three categories and discussed that how
computational models can help in analyzing the illicit activities. The present
study sheds a new light on the area of research that will aid to researchers in
the field as well as the law and enforcement agencies.
