摘要


Since smartphones and mobile internet became popular, mobile advertisement fraud and anti-fraud are two competitors. One tries to suppress the other. Every time a new fraud method is utilized, a specially designed antifraud method will come out soon. We propose a mobile anti-fraud method that uses the rough set theory to end this circle. This method does not target any particular fraud method but observes the differences between user groups. As long as the fraudsters do not own the related data of natural user groups, it is almost impossible for fraudsters to avoid being detected by this method.
