Abstract

Abstract Because of the wide acceptance of computers and digital devices in our daily lives, it is reasonable to conclude that people will use a computer to commit a crime, store the fruits of their crimes or contraband. So, it is necessary to improve traditional criminal investigation skills and develope new technologies. In this sense, digital forensic is the most promising part to counteract these crimes and digital forensic tool is a key. But in reality, it has limitations in choice of forensic tool for digital evidence acquisition and analysis, because there is no standard for tool's performance assessment or reliability. This thesis aims to provide test procedure for the verification of reliability of the digital evidence analysis tool. To do this, this thesis defines functional requirements of digital evidence analysis tool through the analysis of various digital evidence analysis tools. And then, verification items for tool's functional requirements are proposed. Also, test procedures and the expected results for each verification item are proposed and test results on existing forensic tools are presented.
