초록

최근 스마트폰이 널리 보급됨에 따라 이용자의 다양한 정보들이 스마트폰에 저장되고 있다. 그 중 위치정보는 특정 시간의 이용자의 위치나 이용자의 관심지역, 경로 등을 나타낼 수 있으므로 범죄수사 시 유용한 자료로 활용될 수 있다. 그러나 위치 정보에 대한 기존의 포렌식 연구는 단순히 사용흔적이나 위치정보에 대해 확인하는데 그치고 있다. 따라서 본 논문은 안드로이드 스마트폰에 저장되는 위치정보를 로그, 이미지, 각종 애플리케이션 등 다각적으로 접근하여 분석하고, 계층적 군집화를 이용한 통합적인 위치정보 분석모델을 제안한다. 본 논문에서 제안한 모델은 위치정보 분석의 효율성을 높이고 사건에 대한 정보를 제공함으로써 범죄수사과정에 도움이 될 것으로 기대된다.

Recently, as smartphones are widespread, a variety of user's information is created and managed in smartphones. Especially the location information 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 and arson cases, there is a lack of research on location information for digital forensics. In this paper, we analyze the location information from logs, images, and applications on android, and we suggest the integrated model for analyzing location information. The proposed model may be useful in criminal investigation by improving the efficiency of data analysis and providing information about a criminal case.
