플래시 메모리가 각종 IT 기기의 저장장치로 많이 사용되면서 범죄 관련 증거나 단서가 기기 내에 저장되는 경우가 증가하고 있다. 이러한 경우에 기기 내에 저장된 데이터를 완전히 삭제하기 위하여 안티 포렌식 기술인 와이핑 기법을 사용하는데 이에 대응하기 위해서는 플래시 메모리에 저장된 디지털 증거를 분석하기 위한 디지털 포렌식 기술이 필요하다. 플래시 메모리에 저장되어 있는 데이터를 복구하는 기법이 연구되었으나 특정한 상황을 가정한 특정 파일의 복원에 초점을 두고 있다. 하지만 디지털 포렌식 수사에서 범죄 증거뿐만 아니라 범죄 행위에 관련한 증거도 확보할 필요성이 있지만 이와 같은 연구가 미흡하다. 본 논문은 플래시 메모리에서 안티 포렌식 기술인 파일 와이핑으로 삭제된 파일에 대한 와이핑 증거 확보 기법을 제안한다. 제안 내용은 장치 내의 원본파일과 와이핑 파일로 추정되는 블록들을 검색한 후 갱신시각, 파일에 대한 정보를 통해 서로 비교하여 검증한다.

컴퓨터가 현대 생활의 필수 도구로 자리잡으면서 컴퓨터를 매개로 이루어지는 범죄행위에 대하여 법적인 처벌 문제가 중요하게 대두되고 있다. 컴퓨터범죄를 형사적으로 처벌하기 위하여는 디지털증거의 증거능력과 증명력이 인정되어야만 한다. 하지만 디지털증거는 그 특성상 조작, 손상, 멸실의 우려가 높다. 디지털증거가 형사소송법상 유효한 증거로서의 증거능력을 인정 받기 위하여는 데이터의 변형 없이 수집하고 때로는 손상된 디지털 증거를 복구하여 원본과 동일하게 복사하여 정확히 분석한 후 제출되어야 한다. 이와 관련된 학문 전반을 컴퓨터포렌식이라고 하는데 국내법 혹은 국제법적으로 유효한 절차 및 수단에 따라 관련 증거들을 수집하여 함은 물론이고 과학적인 논거들로 입증하는 것이 또한 매우 중요하다. 현재 국내법상 디지털증거에 관한 입법이 없으므로 일반적인 증거증력에 관한 규정과 일부 판례를 차용하여 증거능력과 증명력을 갖춘 컴퓨터포렌식 절차를 제안 한다.

성폭력은 강간, 강제 추행, 성희롱, 도촬 등 상대방의 의사에 반하여 성적 자기 결정권을 침해하는 모든 신체적 정신적 폭력을 말한다. 남성이 가해자이고 여성이 피해자인 경우가 많은 범죄 행위 중 하나이다. 그 중에서 성폭력의 하나인 성추행은 강제추행을 뜻한다. 강제추행이 성희롱과 다른 것은 '폭행이나 협박'을 수단으로 '추행'하는 것이다. 성추행은 성욕의 자극, 흥분을 목적으로 일반인의 성적 수치, 혐오의 감정을 느끼게 하는 일체의 행위(키스를 하거나 상대의 성기를 만지는 행위 등)로, 강제추행은 이러한 추행 행위 시 폭행 또는 협박과 같은 강제력이 사용되는 경우를 말한다. 본 논문에서는 엘리베이터 내에서 이러한 여성의 성 추행 사건을 컬러 히스토그램을 통하여 추출하도록 한다.

전자금융 사기범이 전화, SMS, 이메일을 통하여 통신회사, 경찰청, 검찰청 및 금융감독당국 등을 사칭하여 피해자로 하여금 사칭기관의 위장 홈페이지로 유도하여 피해자의 금융 정보를 불법적으로 취득하여 피해자의 금융자산을 인출해나가는 금융 분야에서 발생하는 특수 사기범죄의 피해가 줄지 않고 있다. 이에 대한 대책으로 금융감독당국과 금융회사는 지연인출제도, 카드론 취급 강화, 공인인증서 재발급 및 사용절차 강화, 대포통장종합관리시스템 구축 및 홍보 강화를 하고 있지만 이들 방법은 전자금융사고 피해가 추정되는 고객뿐만 아니라 그렇지 않은 대다수 정상적인 전자금융거래 이용자에 대한 전자금융거래의 불편을 야기하고 있으며 전자금융사고 발생중의 실시간 이상증후 탐지를 반영하고 있지 않다. 본 논문에서는 금융회사 홈페이지에서의 전자금융거래 이용자의 접속행위, 공인인증서 사용행위, 온라인 송금행위 측면에서 거래행위를 분석하여 전자금융사고 혐의 이상증후에 대해 금융회사의 실시간적이고 능동적으로 대응하는 방안을 제시한다.

This study aims to provide theoretical base in criminal law for engineers in the viewpoint of jurists to encourage interdisciplinary studies on cyber crimes. Apart from seriousness of discussion on torrent cyber crimes, a good effect of the internet networks such as sharing of information has bee emphasized while the evil influence of its side effect has been neglected. Therefore, this study suggests that we need to consider reinforcement of cyber ethics, and legal mind of IT technicians, strict security by managers, active efforts to develop legitimate contents by managers of web hardware and P2P, and reinforcement of punishments against crimes by internet users. And this study approaches new norms on computer and cyber crimes in interpretational sense of criminal law, and provides the theoretical base of the criminal law focusing on traditional theories, assumptions, and precedents involved in regulations against computer virus distribution.

In recent years, there have been opinions in which physicians are liable to the revocation of their medical license if they are sentenced to above a certain level for criminal charges regardless of the types of offenses. Accordingly, a revised bill of law was submitted in the National Assembly, and related discussions are thus expected to commence. Considering the morality and ethics or the level of the rule of law that the general public expects of physicians, as well as the license revocation system in other professional sectors, it is assessed that medical license revocation due to criminal convictions of physicians is appropriate to some degree. However, if a poorly devised system is established based on unrefined inferences or emotional judgements, unexpected side-effects are likely to arise. With regard to serious criminal acts that society generally perceives as unacceptable, it can be assessed that the revocation of physicians' licenses would appropriately protect the general public from threats. However, given the life-saving characteristics of high-risk medical practices, higher malpractice exposures, and social values, it is difficult to assess charges of professional negligence resulting in death(or in injury) and minor offences in the same manner as anti-social criminal offences are handled. Physicians need to be treated the same as any other professions. At the same time, they are engaged in administering medical treatment to patients in the face of great risks as professionals. Under the circumstances, a discussion on the introduction of a more specific and empirical system is needed by considering the intrinsic characteristics of medical treatment and the need for an equitable health and medical policy. Accordingly, based on the above judgment and perception, this study explores the code of ethics for physicians and medical license revocation related to criminal offences at home and abroad, and examines various legislative alternatives appropriate for the Republic of Korea. In doing so, the purpose of the study is to contribute to the development of a reasonable system for handling criminal offences by physicians.

The purpose of this study is to compare with the general and behavioral characteristics between simple and serial arsonists using the data derived from Scientific Crime Analysis System, Criminal Filing Search System, and Crime Information Management System. The analysis and findings reported here are derived from data extracted from 160 arsonists arrested by police officer. The independent variables included such socio-economic characteristic as arsonists' gender, age, occupation, education level, and previous criminal records of arsonists, and finally the general characteristics of the scene of fire settings. The dependent variable is whether or not serial fire setter. To achieve the purpose, the analysis of frequencies and cross-tab were conducted. According to frequence and cross-tab analysis, there are great differences of the general and behavior characteristics between two groups. In the comparison of simple and serial arsonists, serial arsonists are more likely to have previous criminal records, low socio-economic status, unmarried and no cohabitants than simple arsonists. furthermore, serial arsonists are more likely to use garbage papers for fire setting in the scene of the crime, to have mental or psychological problems, and to get involved in fire setting for the psychological pleasure than simple arsonists do. The present research has some obvious limitations. First, the analysis is based only on arsonists arrested by police officers. These may be considerable differences in arsonists arrested by police officers and fire setters not arrested by them. Additional research is needed to assess the extent to which these findings would apply to fire setters not arrested by police officer in Korea. Secondly, the data in this study are cross-sectional and simple cross-tab analysis are used. Potential limitation of cross-sectional data concerns the inability to specify the changes in measures as arsonists behavioral characteristics. Therefore, further studies need to use longitudinal data and more complicate statistical techniques such as correlation analysis, multiple regression analysis, or LISREL models to specify the casual relationships between dependent and independent variables for fire settings. Even if this study has some limitations, it is meaningful in which it first investigated the comparison of simple and serial arsonists focusing on the general and behavioral characteristics between two groups in Korea.

It is a general recognition that more serious criminal acts in a certain area of society should be given more serious condemation than the same general crimnal act. In particular, considering the purpose of the medical treatment and the trust relationship between the doctor and the patient, the sexual violence by doctor in medical field can not be placed on the same line as that of the general public. But the special legislation to solve this through criminal legal sanctions is not desirable. The basic principle of criminal law ist ultima ratio, so the principle of supplementality. It means to try to solve by all possible means and finally to enter with punishment. A flat and hasty Reaction without the considering of the speciality of medical treatment will cause serious cracking in that area. In addition, it will not be able to expect desirable results in legal practice by breaking down the legal system. Rather, administrative regulation is more efficient than punishment sanctions. But the best way is autonomous control by members of the medical area. Penalties in criminal law must make an enterance at the last, and administrative regulation should be timely intervene in specific situations through diversification. In conclusion, state interventions should be farthest in order to proceed to autonomous control of medical area.
