The MPAA(Motion Picture Association of America) warned about serious problems of piracy due to nearly a quarter of all Internet traffic around the globe was related to Internet piracy. Thus, strong legal action is enforced for piracy over nationally through strengthen the copyright law. We in this paper conducted a survey to see whether netizens prefer to download just for the matter of their convenience. Our study becomes a motivation to consider about seriousness of piracy by comparing between Korea and foreign cases. To our surprise, the survey reveals that Korean netizens conspicuously aware of their downloading behaviors outpaces Canadian netizens. Canada lacks the basic protections for the digital environment and is a safe haven for Internet pirates.

This paper critically investigates the cultural phenomenon surrounding the news mobile phone app in which 'curation', relying on the news editing and adaption, has become much more significant than making the news directly. This study affirms the fact that a copying culture which is basically a combinative effect of duplication (alias) and imitation(mimesis) enables us enrich the human beings' creative activities. However, we need to warn the regressive aspects of copying culture challenging the journalistic principles. This study exemplifies a case of Pikicast, which has become the most rapid growing news content mobile app in Korea. By doing a case study, this paper suggests that 'social gift' should be given to the online users as a whole. The communal and social gift would be an alternative way to the unpaid crawling of the news resources from the digital commons by the news content curating corporation such as Pikicast.

Networking revolution provides users with data and resources sharing, distributed processing, and computer communication in cyberspace. However, users may use computers as a way of unauthorized access, system destruction, and leakage of the stored data. In recent trend, incresing of hacking instances which are from domestic as well as abroad reaches to the level of seriousness. It, therefore, is required to develop a secure system for the National Depense computing resources and deploy in practice in the working field as soon as possible. In this paper, we focuss on finding the security requirements of a network and designing Intrusion Detection System using statical intrusion detection and rule-based intrusion detection analysis through accumulating audit data.

Social network service is defined as an online service or communication service based on social relations among people applied the concept of social network. Social collaborative service included in social network service is characterized by the new value of modified content or recreated content made through collaborative creation process between members of the group. It has the remarkable merits such as sharing and collaboration. But, at the same time, it has the latent problems such as content reuse or copy that is not allowed for members to use. It has been emerged that UCC which is a typical example of recreated or modified content has the copyright issues in both creation and publishing step. To resolve this matter, we don't have many appropriate methods except CCL so far. So, in this paper, we define the problem and implement the UCC metadata manager to control metadata reflecting the feature of UCC. We draw the reference metadata element to identify original content utilized re-creation process. After that we define the R.Metadata Loader module based on the use case. Finally, the proposed UCC metadata manager provides the information of referenced content and lets us to identify the relationship between reference contents. So as to implement prototype, we use Kaltura which is CMS using open source and obtain functional extensibility of metadata manager by using open API.

Korea is constructing geospatial information application system for geospatial information utilization, but it is trying to establish a system for joint use of geospatial information system centering on Ministry of Land Transport and Transport due to the problem of sharing. The purpose of this study is to investigate and analyze the geospatial information application system operated by local governments, and to suggest the application of geospatial information application system using unmanned aerial images. As a result of the research, it was found that the functions of existing spatial information application system are concentrated on the public services and it is difficult to share and utilize data between administrative departments. In addition, the utilization of the system using unmanned aerial image has been suggested, and additional functions such as vector display, area calculation, and report generation have been derived to improve the usability of geospatial information application system. If additional functions of spatial information application system are added through further studies in the future, it will be possible to use it as a basic data of field survey and policy decision in related fields. And non-experts will be able to improve the efficiency of work by utilizing highly accurate geospatial information in various fields.

Online firms collect consumers' private information, which serves as a valuable database for marketing activities. In order to encourage consumers to provide their private information, online firms offer high quality websites for consumers who provide private information. However, identity theft, phishing, and pharming, become critical social issues, consumers started to avoid providing their private information to online firms. Thus, consumers often provide false or limited information, which lacks value for practical use for the online firms. The main issue raised in this study is to discuss how online marketing activities has influence on consumers attitude and information providing behavior. From the result, this paper found that websites reputation had greatest impact on willingness of providing information. Also this study revealed that unauthorized use is the key factor for increasing distrust and avoidance of providing information.

The activity to share personal daily life through social media is becoming more common. In this case, photographs as well as text are used a lot; it has been as easy as winking to clip others' photographs just as it's very easy to take and post pictures. If the picture is the photographic work protected by the copyright law, however, the clipping should be paid close attention. If you use others' photographic works without authorization, you infringe their copyright; if you post them on your social media such as blog, you infringe the right of reproduction, interactive transmission and exhibition. Even though the clipping is permitted, if you'd like to use the photographic works for a profit-making purpose, you should get additional authorization. Others' photographic works are occasionally altered and used for the purpose of avoiding the argument in relation to the infringement of copyright; this act means that it's the infringement of the right of reproduction, the right to preserve the integrity and the right of the production of derivative works for degrees of alteration. We can download others' photographic works with a few mouse clicks thanks to the technology of capturing the screen; we have to recognize that all the acts technically possible are not always legal.

Today, the world is evolving into a huge community that can communicate with real-time information sharing and communication based on the rapid advancement of scientific technology and information. Behind this information, the adverse effects of information assets, such as hacking, viruses, information assets, and unauthorized disclosure of information assets, are continually increasing as a serious social problem. Each time an infringement of the invasion and personal information leaks occur, many regulatory policies have been announced, including stricter regulations for protecting the privacy of the government and establishing comprehensive countermeasures. Also, companies are making various efforts to increase awareness of the importance of information security. Nevertheless, information security accidents like the leaks of industrial secrets are continuously occurring and the frequency is not lessening. In this thesis, I proposed a customized security policy methodology that supports users with various business circumstances and service and also enables them to respond to the security threats more confidently and effectively through not a monotonous and technical but user-centered security policy.
