DRM is the ability to brand digital contents with features that ensure copy Protection and affect the way in which digital contents are played back. DRM is a technology that enables the secure distribution, promotion and sale of digital contents on the Internet. The DRM Client System that operates on the untrusted user environments has to meet the requirements of the contents owner, including copyright and contents protection. After the DRM Client System is installed on the untrusted user environments, it verifies and plays digital contents. With these procedures it cuties out user authentication, contents decryption, and license management. During these procedures, the sensitive data, including authentication information, decryption data and license data, must be secured against any illegal access from users. The goal of this thesis is to introduce the implementation of Secure Storage Device which can protect user's authentication key, cryptographic key, and license data in safe where the DRM Client System is running.

The increase in number of streaming platforms and contents thereof, owing to an advancement of cloud environment, has triggered the rapid proliferation of illegally replicated contents as well as legal contents. This necessitates the development of technology capable of discriminating the copyright infringement of various contents. The Korea Copyright Protection Agency operates a video content demonstration system using AI, but it has limitations on distortions such as resolution changes. In this paper, we propose the powerful mechanism using skeleton, which is resistant against distorted video contents and capable of discriminating copyright infringement of platforms streaming illegal video contents. The proposed mechanism exploits the calculation of Hamming distance to the original video by converting collected data into binary ones for the efficient calculation. As a result of the experiment, the proposed mechanism have demonstrated the discrimination of illegally replicated video contents with an accuracy of 94.79% and average magnitude of 215KB.

The purpose of this study is to explore ways to resolve the conflicting issues that are currently applied in medical Act and medical privacy Act through the comparative Analysis of the Privacy Act and the Medical Information Protection Act foreign. the results run to establish the Public Health Act coming for the protection of health information is a characteristic of many countries, France in Europe, the United States and Canada had been running an independent medical information laws are enacted. Prescribes penalties of up to a fairly systematic method from the case records of patients would not have occurred in the management and implementation of the law and the protection of the author of the book focuses on the subject of medical records and physician records between patient confidentiality and privacy it can be seen that the method defined in. This indicates the need for the establishment of an independent medical information laws to protect all records relating to the patient systematically Korea also.

Protection of personal information has significant meaning in current information age. Information of crime victim is one of top in value in that divulgence of the information to perpetrators may threat safety of the victim or cause psychological demage as $2^{nd}$ harm if disclosed to public. Legal system protects the information with scattered statutes including Criminal Procedure Act. Existing studies have been limited to discussion of the single statute without integrated approach. Bearing necessity of the approach in mind, as issues of protection system this research proffers too broad subject of eligible inspection of case document, inactive practice of identity management cards and omission of personal information, and inappropriate punishment on the disclosure or divulgence. After reviewing systems of foreign jurisdictions to get useful implications, this paper suggests several measures with two separate aspect of legal provisions and protection practice.

In recent years, multinational companies' pirate cases for traditional knowledge and genetic resources are growing. Meeting of International Authorities(MIA) agreed that traditional knowledge documentation should be included in the non-patent literature part of the Patent Cooperation Treaty(PCT) minimum documentation as a means of protection. In Korea, Korean Intellectual Property Office(KIPO) and Rural Development Administration(RDA) have played a leading role in traditional knowledge-related protection activities. KIPO's Korean Journal of Traditional Knowledge(KJTK) was selected as a PCT minimum documentation in 2008, and has been serviced through Korean Traditional Knowledge Portal(KTKP) since 2007. RDA has published several books which contain traditional agricultural knowledge and Korean local food information compiled from 1997 to now. Traditional knowledge of RDA is searchable in KTKP from 2010.In this paper, we introduce overview of activities for protection and utilization of traditional knowledge.

As the integrated and large-scale information is extended due to an advanced information system, a possibility of leaking out privacy increases as the time passes by. As a result, the necessity of using a privacy impact assessment (PIA) is emphasized because it can analyze and minimize the element of invasion of privacy. However, an essential audit for personal information protection is not fulfilled because most of the information system audit supervises over physical, managerial, and technical security items of system architecture area so that general items are the only things being checked. Consequently, this paper proposes that in order to minimize the invasion of personal information, the privacy impact assessment should be done. It also presents a procedure and method of personal information protection audit according to the result of the assessment. After applying the suggested method to two projects, it was confirmed that the improvements for protecting personal information were drawn from this paper.

The method of suppressing recidivism through punishment centered on punishment is showing limitations through criminal policy research in many countries. As an alternative to this, a restorative judicial law aimed at returning criminals to members of society through reconciliation and coordination of community members, victims, and perpetrators is emerging as a paradigm for crime prevention and recidivism. Sweden is a representative welfare state and is confirming positive effects through correction of criminals based on restorative justice. In addition, it has a stable system related to the legal protection welfare system, and maintains a low recidivism rate and social security through scientific and reasonable operation using evidence-based principles in the evaluation and certification process of operating programs. However, research on the legal protection system implemented in advanced welfare and correctional countries, including Sweden, is still insufficient in Korea. Therefore, this study aims to explore the direction of the domestic legal protection system through a review of Swedish criminal policy and legal protection system, and to identify insufficient areas and complementary points of the domestic system to lay the foundation for improving the domestic legal protection welfare system and expanding business.

The current juvenile law has to be improved in the following respects: First, there is no clear and objective basis for the process divided into criminal and protective dispositions. Second, the spirit of legislation to protect the boy is understandable, but when reviewing the application process of the juvenile law to actual juvenile crimes, it is hard to find such spirit. Third, in dealing with juvenile protection cases, the outcome and process of disposal should be reflected in the boy's protection ideology. Finally, efforts should be made to shorten the processing period of the case, curb the transfer of violent criminals to juvenile detention center, and integrate the latter part of the first and sixth disposition.

In this study, hydrophobically modified fumed silica was added to the PVDF coating to improve corrosion protection performance. Two types of silane modifiers, trimethylchlorosilane (TMCS) and hexamethyldisilazane (HMDZ), were used for hydrophobic modification of the fumed silica. The composition of modified fumed silica was analyzed by Fourier transform infrared, X-ray photoelectron spectroscopy, and elemental analysis. The dispersion of modified fumed silica in the PVDF coating was observed by the transmission electron microscopy, and the hydrophobicity of PVDF coating was analyzed by the water contact angle. Surface properties were examined by the field emission scanning electron microscopy and scanning probe microscopy. Potentiodynamic polarization was conducted to confirm corrosion protection performance of PVDF coating in terms of hydrophobically-modified fumed silica contents. As a result, the average surface roughness and the water contact angle of the PVDF coating increased with modifier contents. The results of the potentiodynamic polarization test showed an increase of the E_corr values with increase of the hydrophobicity of PVDF coating. Thus, it clearly indicates that the corrosion protection performance of PVDF coating improved with the addition of the hydrophobic-modified fumed silica that prevents the penetration of moisture into the PVDF coating.
