A solution of anonymous email identification based on writing structural pattern

This paper presents a method to analyze the anonymous email in digital forensics. The FP-growth algorithm is used to analyze the user´s email in the method to get the user´s email writing structural pattern. The impact of the user´s writing structural pattern on analysis of anonymous email is different from each other. The AHP method is used to calculate the weight of a user´s different writing structural pattern. For a given anonymous email, writing structural pattern matching and weight calculation can help investigators to make a better decision and find out the author of anonymous email in forensic work.
