계층적 군집화를 이용한 스마트폰 위치정보 포렌식 분석 모델

Abstract

Today, as digital devices are widespread, a variety of user’s private information is created and managed in digital form. Especially the location information in a smartphone can show the user’s position at a specific time and the user’s area of interest, which could be very useful during criminal investigation. Although the location information plays an important role in solving the crimes such as serial murder, rape, arson cases, etc, there is a lack of research on location information for digital forensics. In this paper, we analyze the artifact and the location information from android logs, images, and applications on android devices, and we suggest the integrated model for analyzing location information using hierarchical clustering algorithm. The proposed model may be useful in criminal investigation by improving the efficiency of data analysis and providing information about a criminal case.
