Now we are facing with a possibility of having crimes, which have been only possible offline, in cyber spaces as well.Especially, a recent growth in the use of SNS, promoted by popularization of smart phones, also has led an abrupt increase in cyber crime. It would be important to have a understanding of cyber crime and its characteristics by type as well as factors associated with each type of cyber crime in order to devise appropriate preventive measures against cyber crime. However, most of the previous studies on cyber crimesolely made through literature review or indirect approaches. Therefore, this study has been designed to conduct the interview with actual suspects(criminals) of cyber crime to address factors of cyber crime and to devise specific preventive measures and countermeasures against cyber crime. Especially, among various types of cyber crime, this study aims at addressing the 'trades' and 'financial transaction' of crimes committed using the information and communication network and the 'cyber libel/insult'of crimes committed using unlicensed contents, which have been soared recently and become significant issues. The findings of this study could be beneficial for the society since it has managed to conduct the interview and reveal relationships among major factors of cyber crime. The findings of this study could be used for devising and developing proper preventive and countermeasures against cyber crime, in turn reducing and preventing its damage.

일반적인 사이버 범죄 중에서 포탈사이트 게시판에 명예를 훼손할 목적으로 글을 올린 경우를 생각해보자. 인터넷 웹브라우저 내용을 출력하거나 화면캡쳐 도구를 이용하여 생성한 파일은 웹브라우저 내용을 클라이언트가 임의로 수정하여 출력하거나 화면캡쳐 파일을 수정할 가능성이 존재하고 무결성 보장이 힘들다. 본 논문에서는 실제 내컴퓨터의 모니터에서 보이는 화면은 얼마든지 조작이 가능함을 예를 들어 보일 것이며 화면캡쳐 파일의 무결성 보장을 위한 시스템을 제시하려고 한다.

Internet is in rapid growth from technology to total social environment, so technical and syntax based cyber crime is evolved but also psychological and semantic based one is showing. In this paper, we analyze the cyber-crime cases announced by police, then classify it into social and technical influence. After that, we study the profiling method on psychological view point of cyber-crimes. We expect that it is possible to classify cyber-crimes into the categories rapidly and take less time to analyze and response.

Social Network Service(SNS) users are increasing globally. Within that trend, 'SNS attacking' victims are increasing in social network service space like KakaoStory, facebook, or Instargram as people damage others' personality or reputation. In this paper is to investigate and analyze awareness of negative behavior attributed to disinhibition effect with undergraduates who are the group of people using social network service the most diversely in smart environment and devise preventive measures to reduce social network service attacking victims and attackers. In social network service space, undergraduates are hardly aware of other people's personality, defamation, or invasion of privacy, and the level of guilt they feel towards social network service attacking is seriously low. To solve this problem, this study suggests preventive measures so that they can be equipped with awareness and regulations right for this social network service age and can prevent negative behavior resulted from disinhibition effect.

인터넷의 진화에 따라 우리사회는 매우 빠르게 변화하고 있으며, 이러한 변화를 선도한 인터넷은 앞으로도 개인 맞춤형, 사물 지능화 등으로 진화를 거듭하여 우리 삶에 더욱 큰 변화를 가져올 것이다. 경제적 측면에서도 인터넷을 기반으로 한 다양한 형태의 융합이 산업발전의 새로운 패러다임으로 대두되어 전력, 교통 등 산업간 융합이 가속화되고, 첨단 융합보안기술로 고(高)부가가치 신규 시장의 창출이 가능해질 전망이다. 그러나 인터넷, IT의 발전과 더불어 사이버 공격의 특성이 과거 호기심이나 자기 과시적 행태에서 조직적이고 금전적인 이익을 노리는 방향으로 확산되고 있으며, 인터넷의 익명성과 비대면성으로 인해 불건전 정보의 유통, 저작권 침해, 명예 훼손, 언어폭력 등 개인과 사회의 피해가 점증하고 있는 상황이다. 본고에서는 이러한 환경변화에 맞추어 융합을 통한 가치 창조적 정책 및 선진 인터넷 기반마련, 깨끗하고 안전한 인터넷 이용환경 조성, 글로벌 협력체계 강화 등의 전략 목표 달성을 통해 신뢰할 수 있는 인터넷 및 방송통신융합의 가치창조와 진흥이라는 미션을 완수하기 위한 한국인터넷진흥원의 주요 중점 추진과제를 정리하였다.

The purpose of this study examined how post-traumatic stress, caused when internet users in web portal or social media are defamed in cyberspace, influence on coping behaviour, through the Theory of Reasoned Action's two major factors: Attitude on behaviour and subjective norm. In so doing, it aims to provide a technical and political solution that would fundamentally prevent future victims in cyberspace. In an effort to examine its research theory, a survey was conducted on people who have had the experience of being defamed in cyberspace. The results showed, first, hypersensual has no significant influence over attitude on behaviour and subjective norm. Second, intrusion has no significant influence over attitude on behaviour and subjective norm. Third, avoidance showed significant influence over attitude on behaviour and subjective norm. Fourth, attitude on behaviour and subjective norm showed significant influence on behaviour. This study has both theoretical and practical significance; Unlike previous studies on cyber defamation with qualitative research method, this study employed quantitative method through theory-based approach. In other words, the researcher did not arbitrarily set variables, but utilized the Theory of Reasoned Action for examination.
