We propose a plan to reduce the operational risk of domestic cryptocurrency exchanges for protecting cryptocurrency exchange users and establishing a stable operating environment. For market participants using cryptocurrency exchanges, cryptocurrency exchange risk is greater than the price risk. In the cryptocurrency market, illegal transactions using the anonymity of cryptocurrency are occurring frequently. In addition, loss accidents due to cybercrimes and insider corruptions are continuing. And the resulting losses are passed on to the users of the exchange. In terms of operational risk, we analyze the current situation of domestic cryptocurrency exchanges and present the direction of development of each exchange platform to attract and protect users.

With the recent development of deep learning technology, computer vision-based AI technologies have been studied to analyze the abnormal behavior of objects in image information acquired through CCTV cameras. There are many cases where surveillance cameras are installed in dangerous areas or security areas for crime prevention and surveillance. For this reason, companies are conducting studies to determine major situations such as intrusion, roaming, falls, and assault in the surveillance camera environment. In this paper, we propose a real-time abnormal behavior analysis algorithm using object detection and tracking method.

Awareness that smartphones can be used as tools for criminal activity is prevalent in many organizations, but the functionally smartphone-like smartwatch's potential as a criminal tool is being overlooked. Considering this situation, this research verifies the possibility of information leakage through an insider's smartwatch in a situation where smartphones are controlled by security regulations and technologies, but smart watch are not. By analyzing information related application usage and Wi-Fi connection generated in the smartwatch during the verification process, forensic information and limitations are identified. Finally, this research proposes preventive methods to prepare for potential smartwatch-related crimes, and reconsiders awareness of the possibility of using smartwatches as criminal tools.

It is said that we live in an age of technology. And indeed, science and technology do play key roles to our life of happiness, but they are equally central in all events that threaten it. Science and technology are the means we often turn to in seeking solutions to our problems, and in turn are often the apparent sources of new problems. Thus it is not surprising that they have two aspects at the same time. CCTV has been presented to us as a technical solution to security problems. With the help of CCTV, we can more effectively prevent, detect, and prosecute crimes. With the help of CCTV, both public and private spaces can be made more secure. But of course, CCTV also has a down side. The down side most prominently anticipated has been loss of privacy and proliferation of surveillance. It is largely this potential problem with CCTV that has been regulated against. It is said that one reason for imposing a limitation on individual privacy is the societal interest in the prevention of crime. Accordingly a balance between the need to prevent crime through the use of CCTV and the duty to respect the privacy interests of individual citizens is in need of redress. In other hand, two theories of socio-political philosophy may have provided useful ways of understanding the role of CCTV in contemporary society. Firstly, neo-Marxist frameworks, for instance, stress the use of CCTV to police existing unequal socioeconomic divisions within society and the dominance of particular forms of order based upon materialist agendas. Secondly, Foucauldian frameworks contend that Foucault's notion of panoptic surveillance underpinning (self) disciplinary society is an appropriate template for understanding CCTV in late-modern society. In order to find a new point of valance between security and privacy in the use of CCTV, the participation of each citizen in the discourse to make the new norm is necessary. And to prevent its political misuse, their surveillance, or check for the potential surveillance-power is required.

With the recent changes in the social environment, the growth in the so-called 'five major crimes' has been highlighted as one of the causes of anxiety in Koreans' lives. Many attempts have been made to solve this problem; however, it is still difficult to secure the location information of the socially vulnerable in emergency situations and to precisely identify the features and clothing of criminals and track them using current image analysis technology. Therefore, the development of precision positioning technology and support services along with intelligent security service technology based on spatial information has been given a high priority. This study suggested measures that could be continuously applied to link technologies and services with high linkability by analyzing technologies based on spatial information and other fields. To establish measures for linkage between intelligent security technology and other technologies and services, this study analyzed the existing technologies and research trends in intelligent security technology, and reviewed linkable services according to five criteria established to evaluate their linkability. Based on this analysis, three technologies with high linkability were ultimately selected, and measures for linkage were established. It is expected that the linkage measures derived using the objective evaluation criteria will serve as a stepping stone for promoting active technology linkage and commercialization in the future, even after the completion of this study.

Human trafficking is a booming underground business and is the fastest growing and criminal activity in today's society. The use of coercion or fraud marks the territory of trafficking. Most people trafficked suffer constant threats, violence, and forced acts while imprisoned by their traffickers. Such human trafficking entails significant problems not only for the victims but also for the economies and community health. Large corporations overseas have also been known to partake in the sex slave industry. Another hidden cost to the global economy is the cost of law enforcement and anti-trafficking measures being implemented. Further, sex Trafficking carries many potential health consequences, one of the biggest risks is HIV infection. That means, sex trafficking is an engine of the global AIDS epidemic with one study portraying nearly fifty six percent of all sex slaves having HIV or AIDS. Therefore, many of people are being infected with HIV and many other diseases every day through contact with the sex slave industry costing millions to society and the global economy. in this study, the author presents a case study of trafficking against Nepalese women. Nepalese women being trafficked are found to have a high prevalence of HIV infection. In conclusion and discussion, a few of solutions needed to be addressed for controling human trafficking for sex slavery suggested.

School violence is now considered not only as a problem for a victim and a offender themselves, but also as a social problem that requires responsibilities of school, home, society, and even nation. Crimes and risk factors are various inside and outside of school. In terms of solving those problems, this study examines the actual condition of school violence among students. In addition, it is considered what efforts are conducted by police to establish a safe school environment and the problems that derive from it. Futhermore, this study aims to discuss the ways of using the private security with regard to dealing with school violence. In this society, the expectation of security service from the police is increased as time passed. However, police has limited resources, thus it is beyond their practice. Policing has changed from being monopolized by government to cooperating with various security agents. Community is not considered as the subject for enforcing the law anymore, but as the cooperator for effective policing. With regard to the limitation of police force, using the private security is an effective alternative. Therefore, it is required that private security should be assigned legal authority and shared information with schools in order to patrol the blind spot. Finally, school violence prevention efforts should be conducted by applying physical and electronic security.

Nowadays Internet is the greatest and most participating media of prompting expression with 37 million users in Korea. Internet enables collective communications between social members and contributes to form sound public opinions and to develop democracy while it has negative aspect to distribute massively crime by illegal posting which is forbidden by the Criminal Act. Criminal actors who involve to diffuse information on Internet consist of three categories of information provider, user and internet service provider. Illegal posting generated on Internet is originated from IP and the criminal regulation on it is useless and meaningless because of its countless of users and ambiguous boundary with liberty for expression. Accordingly, the only criminal policy means to prevent danger by illegal posting on Internet is to regulate ISP which saves illegal posting and mediates contacts among users. In spite of it, legislation to regulate ISP is unprepared. The prudent legislative review should be done. And it should be accordance with the doctrines of propriety and vagueness of the principle of "nulla poena sine lege".
