스마트폰을 이용한 산업기술유출 사건에서의 모바일포렌식 조사방법 연구

Abstract

The industry plays a pivotal role in the economic aspect. it is responsible for people’s work sites and lives. Moreover, the technologies, what companies possess, are national wealth of South Korea. However, if companies industrial technologies are leaked by espionage, then it leads country to possibly lose the economic power. These all sorts of industrial technology leakage are occurred with trivial methods such as sending files in real-time through Smartphone and storing data into Smartphone. In other words, one can control the national economy through the small devices. Advancement of Smartphone technology have accomplished to store a lot of high-definition data recently. Therefore, industrial espionage occasionally uses Smartphone to easily leak industrial technologies in the industrial sites. When media data is stored in Smartphones, photos, videos, and thumbnails are generated in various paths. The results of the analysis of these data are attached to this study. Especially, it is not easy to detect industrial technology leakage, given that the industrial security investigation is not a forced investigation by a court warrant but a voluntary investigation by consent of the suspects. Moreover, due to the characteristic of digital evidence, the court strictly interprets the admissibility of digital evidence. Therefore, it is not easy to prove the crime. In this study, we would like to suggest a method of on-site mobile forensics investigation into the exploitation of technology using Smartphones among various industrial technology leakage cases. Especially it is a voluntary investigation, not a forced investigation. Therefore, it is a way to secure the evidence in the field while maintaining the integrity of digital evidence as well as the voluntariness of the suspects.
