Now Broadcasting system of TV has been developed from analogue to digital we call that IPTV(Internet Protocol Television) or DCATV(Digital Cable Television). But, The characteristics of digital broadcasting is the high-quality contents of easily and almost no damage piracy, and Copyright loss is increasing by Internet, P2P(Peer to Peer) and personal path. Nevertheless user's permissions that recorded and reuse of broadcasting can't restraint, And Training Materials etc. use of fair program needs to be separated from illegality. In this paper using a digital certificate permit the use of stored program to authorized user and user of fair purpose, And illegal distribution of restriction design and implement a distribution system.

Digital broadcasting and digital CATV and IPTV will continue in the competition, regardless of how the content of the program was broadcast over the Internet distribution and the damage of piracy is also growing. Excellent quality of the content of the digital CATV sales of DVD and high-density storage media because there is no difference in content and quality is the problem of illegal distribution. However, users can record and reuse program in the position of the guaranteed rights, and the purpose of training in fair and illegal recording and distribution needs to be separate from it. In this paper using a digital certificate recorded by the user and the process to ensure the purpose of illegal distribution of pharmaceutical distribution system design and implementation of the program was broadcast.

Vast amount of information is generated and shared in this active digital As the digital informatization is vividly going on now, most of documents are in digitalized forms, and this kind of information is on the increase. It is no exaggeration to say that this kind of newly created information and knowledge would affect the competitiveness and the future of our nation. In addition to that, a lot of investment is being made in information and knowledge based industries at national level and in reality, a lot of efforts are intensively made for research and development of human resources. It becomes easier in digital era to create and share the information as there are various tools that have been developed to create documents along with the internet, and as a result, the share of dual information is increasing day in and day out. At present, a lot of information that is provided online is actually being plagiarized or illegally copied. Specifically, it is very tricky to identify some plagiarism from tremendous amount of information because the original sentences can be simply restructured or replaced with similar words, which would make them look different from original sentences. This means that managing and protecting the knowledge start to be regarded as important, though it is important to create the knowledge through the investment and efforts. This dissertation tries to suggest new method and theory that would be instrumental in effectively detecting any infringement on and plagiarism of intellectual property of others. DICOM(Dynamic Incremental Comparison Method), a method which was developed by this research to detect plagiarism of document, focuses on realizing a system that can detect plagiarized documents and parts efficiently, accurately and immediately by creating positive and various detectors.

Recently, with the increasing use of smart phones, security issues, such as safety and reliability of the use of the Android application has become a topic to provide services in various forms. An Android application is performed using several important files in the form of an apk file. On the other hand, they may be subject to unauthorized use, such as the loss of rights and privileges due to the insertion of malicious source code of these apk files. This paper examines the Android environment to study ways to define the threats related to the unauthorized use of the application source code, and based on the results of the analysis, to prevent unauthorized use of the application source code. In this paper, a system is provided using a third body to prevent and detect applications that have been counterfeited or forged illegally and installed on Android devices. The application provides services to existing systems that are configured with only the service server that provides users and applications general, This paper proposes the use of a trusted third party for user registration and to verify the integrity of the application, add an institution, and provide a safe application.

Beginning in 1990's, 3D filmmaking reappeared. As almost every job in filmmaking is digitalized, 3D takes advantage of its new software and hardware, and digital friendly customers as well. One reason why Korean cinema should take 3D seriously is that it can resolve the old and tough problem of unemployed human resources in film production. Another reason is the cooperation programs in which universities and 3D companies can join. 3D cinema can create new cinema goers who don't belong the regular viewer. The totally new experience of 3D can bring people to the movie theaters, and this will add up the total movie customers that expand the whole film industry. The newly designed 3D also could take care of piracy of movie file uploading and downloading through internet. 3D cinema would be precious alternative for film industries of Korea.

Due to the rapid progress in network technology, many research on content security technologies is also being conducted in the mobile digital content sector. In the meantime, content protection has been immersed in preventing illegal copying, certifying, and issuance/management certificates, but still have many vulnerabilities in managing or authenticating confidential information. This study aims to strengthen confidential information about content based on dual management of content download rights through mobile phone numbers or device numbers. It also protect replay-attack by building a secure mobile DRM system where digital content is safely distributed based on a three-stage user authentication process. In addition, blockchain-based content security enhancements were studied during the primary/secondary process for user authentication for the prevention of piracy and copyright protection. In addition, the client authentication process was further improved through three final stages of authorization in the use of illegal content, considering that legitimate users redistributed their content to third-party.

The needs for small size and low power consumption of information devices is being implemented with SOC technology that implements the program on a single chip in Internet of Thing. Copyright disputes due to piracy are increasing in semiconductor chips as well, arising from disputes in the chip implementation of the design house and chip implementation by the illegal use of the source code. However, since the final chip implementation is made in the design house, it is difficult to protect the copyright. In this paper, we deal with the analysis method for extracting similarity and the criteria for setting similarity judgment in the dispute of source code written in HDL language. Especially, the chip which is manufactured based on the same specification will be divided into the same configuration and the code type.

They insist that there is no more new stuff in modern art to change every circumstance rapidly. According to this situation, they recreate the works which are made with the existed idea or materials, and also transform creative concept which cites the existing functions with modern meaning. Furthermore they can look into any data everywhere from their daily routine using the internet. And this must become one of the general forms which they imitate others' works which are referred or chosen in modern art. These social complextion is called a parody and pastich is technique of the Post Modernism which is the existence of past. Using the new construction, the parody and pastich which can accomplish some better value and bring other meanings makes original recreation with the concept of copying and repeating. It keeps changing and is shaping up to be different aspect so far. Every field has a little different term using its own expression but it keeps empathizing each other a same essential meaning. Although it is like universal mode of expression, It is fact that the public cannot distinguish what is creation, imitation, or piracy. This thesis shows the concept of it and files for terms which is using like that. At last it selects some artist who worked with parody and pastich analyses and compares them and their works.
