Abstract

This research is about the development of e-forensic tool that extract & analyze different forms of digital evidence that individuals come across in a disaster scene. The tool utilizes digital forensic techniques which makes the tool efficient in any disaster analysis situation. In order for the forensic evidence to be selected as legal evidence, the evidence needs to be proven that it is in its original state with no forgery involved. This is where the e-forensic tool comes in, as its ability to collect digital evidence during investigation has proven; that the tool can keep the evidence in its original state and increase the integrity by generating hash TAG and adding the forensic evidence to a password encoded file.

본 연구는 재해현장에서 발생한 다양한 형태의 디지털 증거물을 채집 분석하는데 있어 디지털 포렌식 기법에 입각하여 효율적으로 재해 현장 디지털 데이터를 채증할 수 있는 e-Forensic 툴 개발에 관한 것이다. 현장에서 채집한 다양한 디지털 증거물이 법적 증거물로 채택되기 위해서는 디지털 증거물이 위변조가 없는 원본과 동일한 상태임을 입증해야만 하는데 이를 본 e-Forensic툴을 이용하여 검증하였다. 이 툴을 활용하면, 현장 수사 중 디지털 파일을 증거로 수집하는 경우에 현장에서 바로 해시값을 생성, 암호화된 디지털 파일에 부가함으로써 디지털 파일의 원본과 사본의 동일성을 보장하고 현장 증거의 무결성을 향상시킬 수 있는 효과가 있음을 증명하였다.
