Victim Impact Statement, adopted as a crime victims' right, has been implemented in Korean criminal justice system since 2007, and known that the statement enlarges victims' right in courts and alleviates their suffering resulted from the crime. The statement, however, has raised concerns of infringing on a defendant's procedural rights. Scholars and practitioners had focused more on the legal issue, overlooking psychological effect of the statement to decision-makers in courts. This research reviews fallacy of impact assessment and therapeutic effect from psychological perspective, and also suggests alternatives to assuage the concerns by admission of the statement.

Various opinions are expressed about the Internet Regulation. Some people argue that it is impossible to control because of the technical characteristics of Internet, while other people argue that it is easy to control. Recently in Korea, a move to reinforce the Internet Regulation through the extension of cyber real-name system is emerging, whereas the concern for its excessive infringement of the Freedom of Expression is increasing. This paper was intended to draw a reasonable direction for Internet Regulation in our society. And accordingly this paper tried to suggest a desirable direction of Internet Control in the future and to draw a criterion for domestic court judgement by analyzing cases of cyber defamation so far. The result of this study proposed that the Freedom for Expression be widely secured in the case of cyber defamation of criticism and political comments upon public officials and that the legitimacy and effectiveness of Internet Regulation be ensured. This result of study is expected to help establish the direction and principle of Internet Regulation in the future around Korea Communications Commission and Korea Communications Standards Commission.

The majority of recent intrusions reveal that the attackers do not use the previous intrusion techniques or network flaw, rather they tend to use the vulnerabilities residing inside the program, which are the running programs on the system or the processes for the service. Therefore, the security managers must focus on updating the programs with lots of time and efforts. Developers also need to patch continuously to update the program, which is a lot of burden for them. In order to solve the problem, we need to understand the vulnerabilities in the program, which has been studied for some time. And also we need to analyze the functions that contains some vulnerabilities inside. In this paper, we first analyzed the vulnerabilities of the standard C library, and Win32 API functions used in various programs. And then we described the design and implementation of the automated scanning tool for writing secure source code based on the analysis.

Disclosure of personal information to be carried out in one of the Administrative Publicity, Administrative agency as specific information about the person who has violated the obligation imposed by the law is an unspecified number people know is through the direct or Internet media it is to be disclosed in an unspecified number of people. This is, indirect sanctions so as to fulfill its obligations by the addition of psychological pressure that exposes the personal information of the fact that in breach of his obligations to the breach of duty and it has been an unspecified number of people know it is a means. However, publication of these personal information, infringement of the moral rights of the Constitution guarantees an individual, of course, not only a matter of law that the right to self-determination of the personal information, has continued also doubts for the effectiveness of the system. As a result, in this paper, to discuss legal issues with the disclosure of management personal information and its improvement measures, and expected to be able to take advantage of the efficient development of the future of personal information disclosure system.

According to the development of information system, many information system and application soft-ware are develop. However, cyber attack and incident have more increased to the development of them. To defend from cyber attack and incident, many organizations has run information security systems, such as Intrusion Detection System, Firewall, VPN etc, and employed information Security person till now But they have many difficulty in operating these information security component because of the lack of organizational management and analysis of each role. In this paper, We propose the formal Cause-Effect Model related with the information security system and administrative mission per each security. In this model, we regard information system and information system operator as one information component. It is possible to compose the most suitable information component, such as information system, human resource etc., according to the analysis of Cause-Effect Model in this paper. These analysis and approaching methodology can make effective operation of each limited resource in organization and effective defense mechanism against many malicious cyber attack and incident.

Automatic obfuscation is known to be the most viable method for preventing reverse engineering intentional1y making code more difficult to understand for security purposes. In this paper, we study and implement an obfuscation method for protecting MS Visual C++ programs against attack on the intellectual property in software like reverse engineering attack. That is, the paper describes the implementation of a code obfuscator, a tool which converts a Visual C++ source program into an equivalent one that is much harder to understand. We have used ANTLR parser generator for handling Visual C++ sources, and implemented some obfuscating transformations such as 'Remove comments', 'Scramble identifiers', 'Split variables', 'Fold array', 'Insert class', 'Extend loop condition', 'Add redundant operands', and 'Insert dead code'. We have also evaluated the performance and effectiveness of the obfuscator in terms of potency, resilience, and cost. When the obfuscated source code has been compared with the original source code, it has enough effectiveness for software protection though it incurs some run-time overheads.

Due to the development of Internet and the collection and usage of the individual information, the infringements of the personal data have been increased rapidly. Regarding the personal data protection in the medical industry, it is clearly described in 'Act on Promotion of Information and Communication Network Utilization and information Protection, etc.'. the law is ratified on the basis of the service provider, therefore, it has its own limitation to be applied to medical industry. Therefore, this paper is to set the security standard and to discuss the range of legal application and considerations on its basis for the domestic medical institution at the electronic medical record system. We exemplify specific applicable content of the electronic signature in the electronic medical record also, present a security assessment item in electronic medical system and set the criteria for the security standard in the medical industry.

Despite the early success story, the pan-industry diffusion of big data has been slow mostly due to lack of confidence of the value creation and privacy-related concerns. The problem leads us to the need to a stakeholder analysis on the adoption process of big data. The present study combines technology acceptance model, task-technology fit theory, and privacy calculus theory to integrate the positive and negative factors on the big data adoption. The empirical analysis was performed based on the survey from the current and potential big data users. Results revealed perceived usefulness, task-technology fit, and privacy concern are significant antecedents to the intention to use big data. Furthermore, there are significant differences in the perceptions of each constructs among groups divided by the types of big data use, with several exceptions. And the control effect was found in the magnitude of the relation between independent variables and dependent variable. The theoretical and politic implications of the analysis are discussed as to the promotion of big data industry.

The traditional text-based password is vulnerable guessing, dictionary attacks, keyloggers, social engineering, stole view, etc. these vulnerability effect more serious problem in a mobile environment. In this study, By using the pattern number to enter the password of an existing four-digit numeric password, User easily use to new password system. The technology on pattern based numerical password authorization proposed in this paper would intensify the security of password which holds existing 10 numbers of cases by authorizing a user and would not invade convenience of use by providing high security and making users memorize only four numbers like old method. Making users not have inconvenience and raising complexity, it would have a strength to an shoulder surfing attack of an attacker. So I study password system that represents the shape-based of number. I propose the new password system to prevent peeking attacks and Brute-force attack, and this proposal is to review the security and usability.
