개발된 장치와 앱을 사용하면 시중에 나와 있는 범죄 예방 어플리케이션과는 다르게 스마트폰에서 물리적인 버튼을 사용하지 않고 사용자의 음성으로 이벤트를 발생시켜 자신의 위치정보를 미리 지정한 전화번호로 SMS를 보내고 자신의 스마트폰에서 사이렌을 자동으로 동작시킴으로서 위험한 상황에서도 편리하게 사용 할 수 있어 범죄 예방에 도움이 될 것이다.

The spatial distribution of crime incidences in urban neighborhoods is a reflection of their socio-economic environment and spatial inter-relations. Spatial interactions between offenders and victims lead to spatial autocorrelation of the crime incidences. The spatial autocorrelation among the incidences biases the interpretation of the ecological model in OLS framework. This research investigates residential crimes using residential burglaries and robberies occurred in the city of Columbus, Ohio, for 2000. In particular, the spatial distribution of incidence rates of residential crimes are accounted in OLS framework using eigenvectors, which reflect spatial dependence in crime patterns. Result presents that handling spatial autocorrelation enhanced model estimation, and both economic deprivation and crime opportunity are turned out significant in estimating residential crime rates.

Online game industry and item trade have grown up fast after 2000. And there has been a perspective that online game and item trade are the cause of the crimes, especially cyber crime like hacking, virus. But there was no positive research about the opinion, so this article studies the relations among online game, item trade and crime. The results suggest that online game and item trade maybe a cause of cyber crime and property crime. But online game and item trade don't increase the total number of crime. That means that online game and item trade substitute the way how crime happens. Online game and item trade substitute no-property crime to property crime.

A Study on the Countermeasures against International Computer Crime focusing on the Police Investigation Procedure. These days, much more intelligent, varied and advanced techniques for computer crimes have been used than for development of technology. In particular, it has been reported that the damages are enormous. Damages of some computer crimes can not be accurately reported. This study is to speculate specific types of computer crimes and obtain its prevention and countermeasures centering on the Police Investigation Procedure. In particular, it is to speculate international cooperation under the condition that global damages occur frequently due to preparation of advanced network environment.

Recently, because credit card crime using a personal credit information is increasing, professionalizing, and spreading the area, the loss occurring from credit card crime is enormous and is difficult to arrest and punish the criminals. At past, crime from forging and counterfeiting the credit card was originated by minority criminals, but at present, the types and appearance of credit card crime is very different to contrasting past crime. The numbers of people using credit card in the middle of 1990's was increasing and barometer of living conditions was evaluated by the number having credit card, therefore this bad phenomenon occurring from credit card crime was affected by abnormal consumption patterns. There is no need emphasizing the importance of personal credit card in this credit society. so, because credit card crime using personal credit card information has a bad effect, and brings the economic loss and harms to individuals, credit card company, and members joining credit card. Credit card crime using personal credit card information means the conduct using another people's credit card information(card number, expiring duration, secret number) that detected by unlawful means. And crime using dishonest means from another people's credit information is called a crime profiting money-making and a crime lending an illegal advance by making false documents. A findings on countermeasures of this study are as follows: Firstly, Diverting user's mind, improving the art of printing, and legitimating password from payment gateway was suggested. Secondly, Complementing input of password, disseminating the system of key-board protection, and promoting legitimations of immediate notification duty was suggested. Thirdly, Certificating the electronic certificates as a personal certificates, assuring the recognition by sense organ of organism, and lessening the ratio of crime occurrence, and restricting the ratio of the credit card crime was suggested.

메신저는 인터넷을 통해 실시간으로 대화를 주고받을 수 있는 소프트웨어로서 사용률이 점차 증가하고 있는 추세이다. 메신저의 사용률이 증가함에 따라 메신저를 사이버 범죄의 하나의 도구로써 이용하는 사례가 발생하고 있다. 메신저가 사이버 범죄에 악용되는 사례가 늘어나면서 전 세계적으로 MSN Messenger, AOL Instant Messenger, ICQ와 같은 외산 메신저 소프트웨어 대한 포렌식 연구가 활발히 진행 되고 있다. 본 논문에서는 현재 국내에서 사용되고 있는 메신저에 대한 포렌식 기법 연구를 통하여 범죄 발생 당시 용의자들의 정보를 획득하고 이를 컴퓨터 범죄 수사에 활용하는 방안을 제시한다.

최근 인터넷의 급속한 발전을 기반으로 국경을 초월하여 인터넷을 이용한 각종 해킹, 사이버 공격 및 범죄가 기하급수적으로 증가하고 있다. 이와 같은 상황에서 각종 침해사고로부터 시스템, 네트워크 및 중요한 정보를 보호하기 위한 다양한 보안 강화 시스템이 개발되어 적용 운용되고 있지만, 현재 적용되어 사용되고 있는 보안 강화 시스템들은 해킹, 공격 및 범죄가 발생된 후 이를 막기 위한 방법으로 수동적인 기능으로 사용되고 있다. 그 결과 해킹, 사이버 공격 및 범죄를 사전에 미리 방지하는 데는 한계를 갖고 있는 것이 사실이다. 때문에, 현재 역추적 분야에서는 해킹, 사이버 공격 및 범죄가 발생할 경우 능동적이고 실시간으로 빠른 추적이 가능한 보안 강화 시스템을 목표로 하는 연구가 진행되고 있다. 이에 본 논문에서는 TCP/IP 기반의 다양한 역추적 기술을 각각 분석하고 역추적 기술을 발전시키기 위한 요구사항을 분석하여 연구동향에 관하여 살펴보고자 한다. 본 논문은 참고문헌 [16]의 결과를 활용해 작성했으나, 표준화 동향과 요구사항, 요구사항에 근거한 기존 방식들의 특징을 제시하였다.

최근 발생한 사이버 범죄 경위를 살펴보면 범죄 목적이 분명하고 이를 달성하기 위한 수단이 치밀하여 비교적 높은 보안 수준을 가진 기업이라도 사이버 범죄 행위에 노출되어 피해를 입는 사례가 빈번히 발생하고 있다. 특히 기업환경에서 업무 효율을 높이기 위해 전자결재나 스마트워크 등을 도입하여 업무의 많은 부분이 컴퓨팅 장치에 의존적이 되면서 사이버 범죄에 대한 위협이 늘어나고 있다. 본 논문에서는 악성코드 또는 이를 이용한 악성행위로부터 기업 환경을 보호하기 위한 보안 시스템의 이상적인 요구사항에 대해 제안한다.

The guarantee of citizens' safety from crime is the reason for a nation's existence according to the social contract, and it is also a salient task in securing the citizens' right to the pursuit of happiness, which is a constitutional right expressing the nation's duty to its citizens. First, a procedure must be made mandatory that corresponds to the Miranda rule applied during the arrest of criminal suspect, which verifies whether there exists a risk of retaliatory crime to the victim of crime, crime reporter, or witness following their report of a crime or testimony. A measure to punish those who violate this should be devised. The second is the improvement of related laws and systems, such as expanding the scope of persons subject to protection from retaliatory crimes under the current law and strengthening information protection. Third, a retaliatory crime risk evaluation index must be developed, and the evaluation results must be quantified to clearly state measures and responsibilities, in detail, for personal safety at each level of intensity. The fourth is the expanded implementation of proactive personal safety measures for victims of crime and witnesses, as well as the development and application of advanced techniques. The last is a change in the perception s of those working for the judicial body. From the initial investigation stage of the crime to the diagnosis regarding the possibility of retaliation perpetrated on an ex-convict through psychological tests, systems of general cooperation, and mutual assistance must be established.

Needs about safety of residents are important in urbanized society, elderly and small-size family. People are looking for safety information system and device of CPTED. That is, Needs and Installations of CCTV increased steadily. But, scientific analysis about validity, systematic plan and location of security CCTV is nonexistent. It is simply put these devised in more demanded areas. It has limits to look for safety of residents by increasing density of CCTVs. One of the characteristics of crime is clustering and stong interconnectivity. So, exploratory spatial data of crime is geo-coded using 2 years data and carried out cluster analysis and space statistical analysis through GIS space analysis by dividing 18 variables into social economy, urban space, crime prevention facility and crime occurrence index. The result of analysis shows cluster of 5 major crimes, theft, violence and sexual violence by Nearest Neighbor distance analysis and Ripley's K function. It also shows strong crime interconnectivity through criminal correlation analysis. In case of finding criminal cluster, you can find criminal hotspot. So, in this study I found concept of hotspot and considered technique about selection of hotspot. And then, selected hotspot about 5 major crimes, theft, violence and sexual violence through Nearest Neighbor Hierarchical Spatial Clustering.
