Conclusion is like below. First, as a private security area's mutual relationship and development device, it is necessary to bring up corresponding-terror expert. Second, a privatized corresponding-terror research center is necessary. Third, the importance of privatization's role for the corresponding-terror prevention law establishment. It is considered that a diversified examination research that can minimize a violation of human rights by bringing up various corresponding-terror expert, paradigm shift of workers related security area, and construct corresponding- terror education equipment as well as education content, it is not a special group's authority, should be continued by a following research. Academical area of terrorism's construction is necessary. You need to approach by private initiatively boldly with the academic world as an active mutual cooperation politically, culturally, socially, internationally, etc, rather than developing national institute initiatively. Also, in a following research, an academical research about a correlation of crime, war, terror should be done deeply, variously. It is necessary to establish an academic foundation of terror study.

Digital forensics refers to finding electronic evidences related to crimes. As cyber crimes are increasing daily, digital forensics for finding electronic evidences is also becoming important. At present, various aspects of digital forensics have being researched including the overall process model and analysis techniques such as network forensics, system forensics and database forensics for digital forensics. Regarding database forensics, only analysis techniques dependent on specific vendors have been suggested. And general process models and analysis techniques which can be used in various databases have not been studied. This paper proposes an integrated process model and analysis technique for database forensics. The proposed database forensics model (DFM) allows us to solve problems and analyze databases according to the situation and purpose, and to use a standard model and techniques for various database analyses. In order to test our model(DFM), we applied it to various database analyses. And we confirmed the results of our experiment that it can be applicable to acquisition in the scene as well as analysis of data relationships.

The 「Act on Special Cases concerning the Punishment of Crimes of Domestic Violence」 still has various problems in the legal system and enforcement process. Contrary to the original intention of the legislation, it is operated very passively in terms of state intervention and punishment of domestic violence actors in actual operation. Even if it is treated as a home protection case, if you look at the details of the protection disposition, there is a problem that the decision on the protection disposition is biased towards a specific type of protection disposition. In order to improve this, the need for cooperation and active intervention between state agencies is required. In addition, it is necessary to establish a legal basis for a request for personal protection by recognizing the status of a victim who reported domestic violence as a crime reporter. In addition, in order to secure the effectiveness of the protective disposition, it is necessary to strengthen sanctions for non-compliance or violations of the protective disposition.

Since there are no related laws and regulations in the Korean private investigation industry, anyone can freely operate it if they report the business to the tax office. The reality is that companies hire PI to investigate rival companies and employees for specific reasons, as they generally rely on individual requests. The Korean PI industry is divided into two parts. The first are retired police officers and investigators who have experience in criminal investigation. The second are private citizen who can conduct investigation service activities runs a PI agency after everyone has registered with the tax office. It is no exaggeration to say that the current legal conflicts and legal problems that arise in the PI service cannot be ruled out because civilians are relatively less knowledgeable than PIs and legal experts. Therefore, in order for PI industry to operate stably in Korea, we will first study the concept and type of PI industry, comparative analysis of past PI laws, current status and reality of PI industry, and study the current status and references.

Recently, in the cyberspace, the posts that have only insults and abuses without the fact are getting spread rapidly as a trend, it makes the damage to people also, and the social concerns have been raised about its phenomenon. Meanwhile, because of the insulting actions that performed in cyberspace, the results of infringement of personal rights conditions getting difficult to repair. Also, it is difficult to find who the person who acts as a perpetrator is. So, it is hard to report a crime or sued for damages, also, it is really difficult to deal with a criminal contempt. Also, cause of a lot of deficient areas, the Cyber Insult Crime act is need and strengthened penalties or Mitigation about the crime subject to victim's complaint are need. However, give the criminal penalties to criminal is sufficient. So, to construct a new special criminal law, it is not advisable. Thus, governed by the Criminal Code Section 311 is preferably.

Biographical information about people is usually collected and provided by a company or an institute which has a specific standard to select people for service. Recently, user oriented contents service like Wikipedia has started biographical information service, Wikipedia Biography Portal, in which users select people and freely describe about them. This study collected 500 biographical data from three categories of Wikipedia biography portal such as criminals, faculty, and directors. The contents of data from each category were analyzed with the word frequency and the divergence indicator to identify the characteristics of each category. As a result, divergency indicator is effective to represent the differential factors of each category. This study provides word clouds of top 100 word with divergence indicator and top 100 common words of three categories with word frequency as a guide for users to write about a person in these categories and for editors to accept and monitor the biography from users.

Recently, video-taping equipment such as CCTV have been seeing more use for crime prevention and general safety concerns. Since these video-taping equipment operates all throughout the day, the need for security personnel is lessened, and naturally costs incurred from managing such manpower should also decrease. However, technology currently used predominantly lacks self-sufficiency when given the task of searching for a specific object in the recorded video such as a person, and has to be done manually; current security-based video equipment is insufficient in an environment where real-time information retrieval is required. In this paper, we propose a technology that uses the latest deep-learning technology and OpenCV library to quickly search for a specific person in a video; the search is based on the clothing information that is inputted by the user and transmits the result in real time. We implemented our system to automatically recognize specific human objects in real time by using the YOLO library, whilst deep learning technology is used to classify human clothes into top/bottom clothes. Colors are also detected through the OpenCV library which are then all combined to identify the requested object. The system presented in this paper not only accurately and quickly recognizes a person object with a specific clothing, but also has a potential extensibility that can be used for other types of object recognition in a video surveillance system for various purposes.

An unmanned aerial vehicle(UAV), commonly known as a drone, is an aircraft without a human pilot aboard, which is operated by wireless device. A drone provides the capability for the aerial search and traffic control as a police equipment. It has benefits for the missions for the aerial photography with the high resolution camera which can replace eye-dependent search processes. Moreover it has advantage of retrieving several times for the recorded videos. However, if the law enforcement agency misuse and overuse a drone for investigations and search missions without certain regulations and principles, it breaches privacy and personal information infringement. In this paper, we issue a lawful challenges on drone operations and discuss solutions to those challenges.
