Currently, under being related with confiscation method of digital store medium from the court of justice, "the sorting confiscation method of principle, the exceptional medium confiscation method" from in section3 no.106 of the criminal procedure code disregard the actual fields of investigation. What is more, there are many difficulties to execute cases by observing this for the achievement of confiscation purpose. At this point, I present the problems of the present confiscation search method and the desirable scene confiscation search method and the improvement program under the new technology circumstance.

Electronic medical records in the hospital information system are the important evidence related to the crime and are subject to search and seizure. In the case of a large general hospital, it is possible to search for seizures through cooperation of the staff, but it is impossible in small hospitals. The investigation agency copies the database of electronic medical records and then selects relevant content. This approach has an issue of excessive search and seizure. In this paper, we propose field selection procedures and methods for electronic medical records while ensuring integrity, reproducibility, and chain of custody. Currently, it is necessary to study the procedures and methods of search and seizure of medical information system so that it can respond to next changing cloud hospital information system.

이벤트 로그(Event Log)는 윈도우 운영체제에서 시스템 로그를 기록하는 형식으로 시스템 운영에 대한 정보를 체계적으로 관리한다. 이벤트는 시스템 자체 또는 사용자의 특정 행위로 인해 발생할 수 있고, 그러한 이벤트 로그는 시스템의 시작과 종료뿐만 아니라 기업 보안 감사, 악성코드 탐지 등 행위의 근거로 사용될 수 있다. 본 논문에서는 PC 종료 관련 실험을 통해 이벤트 로그와 ID를 분석하였다. 분석 결과를 통해 PC의 정상 및 비정상 종료 여부를 판단하여, 현장 압수·수색 시 해당 저장매체에 대해 선별압수·매체압수의 해당 여부 식별이 가능하다. 본 연구는 현장수사관이 디지털증거 압수·수색 시 절차적 적법성과 증거능력 확보의 근거 활용에 기여할 수 있다.

안티 포렌식 기술은 정보보안에는 효과적이지만 해당 기술을 악용하여 증거를 은닉하거나 증거 인멸에 사용할 경우 이로 인해 수사에 걸리는 시간이 길어지거나 수사관이 중요한 증거를 찾기 힘들게 만든다는 점에서 디지털 포렌식 수사에 악영향을 주는 요인으로 작용할 수 있다. 또한 우리나라의 경우 선별압수를 원칙으로 하지만 안티 포렌식 흔적이 발견될경우 전체압수가 가능해지기 때문에 수사관이 하드웨어 내에서 안티 포렌식 활동이 이루어졌는지 여부를 파악하는 것이중요하다. 따라서 본 연구에서는 안티 포렌식 중 File wiping 도구의 실행이 Windows 아티팩트에 남기게 되는 흔적을 분석하고 본 연구를 확장시켜 향후 연구의 방향성과 수사관들이 File wiping 도구의 실행 흔적을 손쉽게 파악할 수 있도록 할 수 있는 방안을 모색해보고자 한다.

Because of the evolution of mobile devices such as smartphone, the necessity of mobile forensics is increasing. In spite of this necessity, the mobile forensics does not fully reflect the characteristic of the mobile device. For this reason, this paper analyzes the legal, institutional, and technical considerations for figuring out facing problems of mobile forensics. Trough this analysis, this study discuss the limits of screening seizure on the mobile device. Also, analyzes and verify the mobile forensic data acquisition methods and tools for ensuring the admissibility of mobile forensic evidence in digital investigation.

The law enforcement agencies in the worldwide are confiscating or retaining computer systems involved in a crime/civil case, if there are any, at the preliminary investigation stage, even though the case does not involve a cyber-crime. They are collecting digital evidences from the suspects's systems and using them in the essential investigation procedure. It requires much time, though, to collect, duplicate and analyze disk images in general crime cases, especially in cases in which rapid response must be taken such as kidnapping and murder cases. The enterprise forensics, moreover, it is impossible to acquire and duplicate hard disk drives in mass storage server, database server and cloud environments. Therefore, it is efficient and effective to selectively collect only traces of the behavior of the user activities on operating systems or particular files in focus of triage investigation. On the other hand, if we acquire essential digital evidences from target computer, it is not forensically sound to collect just files. We need to use standard digital evidence container from various sources to prove integrity and probative of evidence. In this article, we describe a new digital evidence container, we called Xebeg, which is easily able to preserve collected digital evidences selectively for using general technology such as XML and PKZIP compression technology, which is satisfied with generality, integrity, unification, scalability and security.

It requires professional knowledge and much time to judge intellectual property rights infringement. The duties of customs administration are the balance between the propositon of trade facilitation through rapid clearance and the thesis of social security through exact examination. There is a view that the criminal procedure law control is necessary to the goods inspection of clearnce procedure if it is related to crimianl investigation. However, it seems that the customs law does not consider the goods inspection investigation as the investigation under judicial control, but only the mere administrative investigation. It can be said that the inspection of goods by customs law functioning as a clue of investigation is confined to the ordinary goods inspection, including the screening test. Searching for specific articles by specific informaition should be under the control of criminal procedure law because it constitutes the commencement of criminal investigation in criminal cases. This interpretation could be an opportunity as a harmonious operation between the goods inspection of customs clearance and the search and seizure of criminal procedure.
