As digital economy has dramatically evolved, new intellectual property rights protection has emerged as a pivotal issue which companies need to actively restxnid to. At the new digital era, the possession of new intellectual property rights determines the company values, and thus the protection of new intellectual property rights is getting more importance in the dimension of global competitiveness. The paper analyzes the changing aspect of digital economy and e-commerce paradigm, and explores the protection plan of new intellectual property rights focusing on e-commerce and digital goods transaction so that it can help the companies to strengthen their global competitiveness. After various case studies, we can find out that even though the companies have difficulty in settling out the strategies and policy due to the radical change of cycle in internet-centered digital economy, companies need to establish the systemic strategic plan to protect the new intellectual property rights stage by stage. Also, appropriate legal, institutional basis to protect the new intellectual property rights should be rearranged. The unsloved problems which relates with the protection of new intellectual property rights will be left for next research project.

GPS(Global Positioning System) service is more important than other wireless services. The GPS is necessary protected from any other interference signals. Therefore, GPS protection ratio was calculated on the basis of bit error rate(BER) in this paper. Simulation results show that the allowable maximum interference power is -190 dBm/Hz and the ratio of interference to noise(I/N) is -16 dB. The achieved protection ratio is available to be applied as the protection criteria of GPS in considering the implementation margin of 4 dB. As a result, the proposed protection ratio of GPS is expected to give standard for a stable GPS service.

In an information society, privacy protection is one of the most important ethical issues. In medical institutes in which personal medical information is collected and stored, in addition, a privacy breach can cause a serious damage on personal lives. This study attempted to develop privacy concern measurement tool in personal medical information to measure patients' concern on their medical information from medical service consumers' perspective and verify its validity. For this, privacy concern measurement tool in personal medical information was developed based on the results of previous studies. After performing Exploratory Factor Analysis(EFA) and Confirmatory Factor Analysis(CFA) on the measurement tool, its reliability and validity were verified. It appears that the measurement tool would be useful in developing decent privacy protection policy after investigating citizens' concern on the protection of personal medical information and domains they are interested in. For medical institutes as well, they would be helpful in coming up with a reasonable plan after figuring out problems in the protection of personal medical information and current status.

It is de-identification that emerged to find the trade-off between the use of big data and the protection of personal information. In particular, in the field of medical that deals with various semi-identifier information and sensitive information, de-identification must be performed in order to use medical consultation such as EMR and voice, KakaoTalk, and SNS. However, there is no separate law for medical information protection and legislation for de-identification. Therefore, in this study, we present the current status of de-identification of personal information, the status and case of de-identification of medical information, and finally we provide issues and solutions for medial information protection and de-identification.

Many studies have been done on secure operating system using secure kernel that has various access control policies for system security. Secure kernel can protect user or system data from unauthorized and/or illegal accesses by applying various access control policies like DAC(Discretionary Access Control), MAC(Mandatory Access Control), RBAC(Role Based Access Control), and so on. But, even if secure operating system is running under various access control policies, network traffic among these secure operating systems can be captured and exposed easily by network monitoring tools like packet sniffer if there is no protection policy for network traffic among secure operating systems. For this reason, protection for data within network traffic is as important as protection for data within local system. In this paper, we propose a secure operating system trusted channel, SOSTC, as a prototype of a simple secure network protocol that can protect network traffic among secure operating systems and can transfer security information of the subject. It is significant that SOSTC can be used to extend a security range of secure operating system to the network environment.

As of July 1. 2001, the Law of Information 8t Telecommunication Protection has been compulsory to audit protection status on national information and Telecommunications Infra facilities such as communication, electricity, waterworks, airport, railway, primary facilities of government and the first financial circles. In U.S. institutions, organizations and corporations in each field are trying to prepare for Safe Har-bor agreed on Internet privacy regulation between U.S. and Europe to be effective in 2003. The Safe Harbor was motl-vated by strict European standard. Other countries make privacy and information protection law according to their own interest. Therefore Korean technical experts have to develop the law responding to national interest and public welfare. Besides scientific Held, experts in the field of politic, economy and academy also have to work hard to develop the law.

In wavelength-division-multiplexing(WDM) networks a link failure may cause the failure of several high-bit-rate optical channels, thereby leading to large data loss. Recently, various protection and restoration mechanisms have been proposed to efficiently deal with this problem in mesh networks. Among them, dedicated path protection(DPP) is a promising candidate because of its ultra-fast restoration time and robustness. In this work we investigate the issue of planning and optimization of WDM networks with DPP. Integer linear programming(ILP), in particular, is one of the most common exact method to solve the design optimization problem for protected WDM networks. Traditional ILP formalizations to solve this problem rely on the classical flow or route formulation approaches, but both these approaches suffer from a excessively high computational burden. In this paper, we present a variable-aggregation method that has the ability of significantly reducing the complexity of the traditional flow formulation. We compare also the computational burden of flow formulation with variable aggregation both with the classical flow and route formulations. The comparison is carried out by applying the three alternative methods to the optimization of two case-study networks.

This study applied the Theory of Reasoned Action by Fishbein & Ajzen(1975) as the grounded theory and adopt sanctions of the General Deterrent Theory and protection motivation of the Protection Motivation Theory as the antecedents to discuss the theoretical factors and the cases of application in the field of information security. Then, it adopted subjective norm, a variable of the Theory of Reasoned Action, as a parameter to analyze the causality of sanctions, perceived vulnerability, response cost, and self-efficacy with the intention to follow the information security policies. As a result, all of the antecedents except for sanctions had causality with the intention and subjective norm proved its mediating effect as a parameter between the antecedents and the intention.

In order to achieve the goal of protecting medical images, some existing watermark techniques for medical image protection mainly focus on improving the invisibility and robustness properties of the method, in order to prevent unnecessary medical disputes. This paper proposes a novel copyright method for medical image protection based on visual secret sharing (VSS) and cellular automata transform (CAT). This method uses the protected medical image feature as well as VSS and a watermark to produce the ownership share image (OSI). The OSI is used for medical image verification and must be registered to a certified authority. In the watermark extraction process, the suspected medical image is used to generate a master share image (MSI). The watermark can be extracted by combining the MSI and the OSI. Different from other traditional methods, the proposed method does not need to modify the medical image in order to protect the copyright of the image. Moreover, the registered OSI used to verify the ownership and its appearance display meaningful information, facilitating image management. Finally, the results of the final experiment can prove the effectiveness of our method.
