In recent years, advanced in digital technologies have created significant changes in the way we reproduce, distribute and market Intellectual Property (IP). DRM for multicast contents is complicated risk, the further technology development and human demand, this approaching is still being researched by the scientist and all by the company which is conducting in piracy management reduced, and every country has national policy to make this consortium to limit piracy properties, based on this paper research development, just only two approaching to reduce piracy in DRM they are Industrial Property (IP) and Copyright. In this paper, we are not only figuring and analyzing about the processes to reduce and limit the piracy and unprotected copy law but also describing about the encryption process, watermarking and digital signature process algorithms. The basic concepts of this encryption process for web-based multicast content in DRM are implemented in Java. We conduct this method is a computerized through web based application system approaching to reduce unprotected copy and piracy. Which is used in DRM for multicast content in every section, by providing a fundamental in information technology development, we believe this research is reliable to prove that is unprotected copy, and piracy can be reduced by protecting with this paradigm.

Recently, with the diversification of media services and the development of smart devices, users have more opportunities to use digital content, such as movies, dramas, and music; consequently, the size of the copyright market expands simultaneously. However, there are piracy sites that generate revenue by illegal use of copyrighted works. This has led to losses for copyright holders, and the scale of copyrighted works infringed due to the ever-increasing number of piracy sites has increased. To prevent this, government agencies respond to copyright infringement by monitoring piracy sites using online monitoring and countermeasure strategies for infringement. However, the detection and blocking process consumes a significant amount of time when compared to the rate of generating new piracy sites. Hence, online monitoring is less effective. Additionally, given that piracy sites are sophisticated and refined in the same way as legitimate sites, it is necessary to accurately distinguish and block a site that is involved in copyright infringement. Therefore, in this study, we analyze features of piracy sites and based on this analysis, we propose an intelligent detection technique for piracy sites that automatically classifies and detects whether a site is involved in infringement.

본 연구는 디지털 콘텐츠의 불법복제와 관련하여 이에 영향을 미치는 다양한 요인을 분석하고자 이러한 행위가 비교적 빈번하게 발생한다고 판단되는 대학 현장에서의 불법행위에 초점을 두고 사용자의 윤리적 성향과의 상관관계를 분석하였다. 합리적 행동이론을 토대로 디지털 콘텐츠 불법복제의도, 태도, 주관적 규범, 불법복제 적발시 예상되는 처벌의 심각성 등의 연구요인을 도입하고 설문조사를 통해 연구모형의 타당성을 검증하였다. 295개 설문자료를 이용하여 가설 검증을 시도한 결과, 처벌의 심각성은 주관적 규범과 태도에 영향을 미치며, 이 두 요인은 디지털 콘텐츠 불법복제의도에 유의한 영향을 미치는 것으로 나타났다. 또한 윤리인식 설문이론을 토대로 하는 상대주의 개념을 조절변수로 설정하여 연구모형을 구성하는 계수간의 차이를 분석하고 시사점도 함께 논의하였다.

In recent years, digital content has become easily accessible because of internet technology. Representative examples of such digital content include various types, such as music, TV, (program, sport, drama etc.) and films. However, there are cases where internet technology is used in illegal ways without the authorization of the copyright holder for digital content. Such actions have a direct impact on copyright owners' profits and further affect the development of the digital culture industry adversely. Therefore, in this study, we analyze features to detect piracy sites that cause copyright infringement. Further, we develop a piracy site detection crawler based on these features and present the analysis of its performance.

As used product transactions are currently on the rise, the demand for transactions of secondhand digital content will grow in the future; thus, learning to make secure transactions while avoiding cyber attacks becomes an important issue. In this paper, we combine the new buyer's secret key, the new buyer's watermark to embed in resold digital content, and the reseller's encrypted watermark, which can prove legal ownership of the reseller. Using the privacy homomorphism property of RSA and exponential calculus, the original seller of digital content can verify the legality of the reseller and the new buyer. We also reduced the load of encryption/decryption digital content using a partial encryption/decryption algorithm to make our protocol more efficient and practical. In the proposed protocol, the seller is not able to conduct piracy and easily frame any other innocent secondhand buyer when a case of piracy is found. In fact, piracy can be clearly traced using the privacy homomorphism property of RSA and the embedded watermark mechanism. Further, in the proposed protocol, the seller himself can trace the piracy using exponential calculus. Since it is unnecessary to trust third party participation, the conspiracy problem is resolved and the new buyer is not required to participate in the dispute. Moreover, the seller, reseller and new buyer can simultaneously benefit from the secondhand transaction.

본 연구는 디지털 콘텐츠 저작권 침해가 가장 빈번히 일어나는 대학 교육 현장에서의 침해행위에 영향을 미치는 다양한 요인의 분석에 주된 목적이 있다. 이를 위해 합리적 행동이론에 이론적 기반을 두고, 대학의 학부 및 대학원 재학생의 저작권 침해의도와 태도, 사회적 영향, 저작권 침해 적발시 예상되는 처벌수준, 재미, 콘텐츠 접근의 용이성, 저작권 관련 지식수준, 촉진조건 등의 요인을 도입하고 설문조사를 통해 모형의 타당성을 검증하였다. 335개 설문자료를 이용하여 가설 검증을 시도한 결과, 태도와 사회적 영향은 모두 침해의도에 유의한 영향을 미치며, 사회적 영향, 재미성, 콘텐츠 접근의 용이성 등이 태도의 선행요인으로 유의한 것으로 분석되었다. 다만 지식수준이 태도에 미치는 영향은 미미한 것으로 나타났다. 사회적 영향의 선행요인도 접근 용이성, 처벌의 심각성 그리고 촉진조건 순으로 모두 유의한 영향을 미치는 것으로 분석되었다. 그 외 본 연구결과의 학술적, 정책적 시사점도 함께 제시하였다.

To counter-attack against piracy, the movie industry is continuously developing new technologies for the protection of intellectual properties, only to find them instantly useless especially in the digital age. This study shifts the focus from technology to customer behavior, and analyzes customer behaviors vis-à-vis piracy using economic models. The theoretical model of optimal holdback strategy under the threat of piracy was derived and the result shows that holdback can be used as a tool not only for hedging the loss due to piracy, but also for reducing piracy. Based on the theoretical model, we suggested proper holdback strategy for each type of movie piracy.

The wide use of digital media during the past few years, has led to an increase of digital piracy and tampering. To deal with these problems, the concept of digital fingerprinting has been introduced. Digital fingerprinting is an effective method to identify users who might try to redistribute multimedia content. In this paper, we propose new digital image fingerprinting techniques using watermark shifting scheme and concept of domain.

본 연구에서는 학생들의 디지털 콘텐츠 불법복제를 방지하기 위한 교사들의 태도와 노력에 미치는 다양한 요인을 분석하고자 하였다. 본 연구는 Ajzen과 Fishbein에 의해 개발된 합리적 행동 이론에 기반을 두고 있다. 177명의 현직 교사를 대상으로 실시한 설문 결과를 토대로 이루어졌으며, 가설 검증을 위해 PLS(Partial Least Square) 모형이 사용되었다. 검증 결과, 학생들의 디지털 콘텐츠 불법복제를 방지하기 위한 의도에 교사의 태도와 사회적 영향력이 긍정적인 영향을 미칠 것이라는 가설은 유의한 것으로 나타났다. 또한, 교사의 인식수준과 불법복제에 대한 처벌수준도 의도에 직 간접적으로 영향을 미치는 것으로 나타났다. 그러나 태도나 의도에 영향을 미칠 것으로 예상한 교사의 효능감에 대한 가설은 기각되었다. 연구 가설의 검증을 통해 결론적으로, 학술적이고 실질적인 결과들이 논의되었다.

As the global smartphones market is growing at a brisk pace, their associated mobile applications are becoming increasingly ubiquitous in our daily life. The growth of mobile application business is explosive. Like other digital contents businesses, illegal downloads of copyrighted mobile applications become major obstacle in the future of the industry. In spite of anti-piracy efforts, the phenomenon has been getting worse. It is necessary to change the focus of current deterrence policies and strategies. This study investigates the factors influencing smartphone applications piracy behavior. For better understanding of illegal behavior, a research model of potential determinants for the piracy behavior is developed and empirically tested via path analysis using structural equation modeling. Findings show that social factors, beliefs concerning benefits from piracy, self-efficacy, and habit have significant effects on attitude toward smartphone application piracy. The result also shows perceived risks and facilitating conditions were not significantly related to their attitude. Implications for research and practice are discussed.
