In this paper, we present an intellectual property management and protection (IPMP) system in a broadcasting environment to provide mechanisms for copyright and contents protection that are compliant with the MPEG-2 and MPEG-4 IPMP Extension (IPMPX) specifications. The technology for processing IPMP related information was exploited, and a terminal model has been successfully designed and implemented. In addition, interoperability, which is the main objective of MPEG-2/4 IPMPX, has been addressed in detail. The experimental results show that the implemented system performs the IPMP process well, meeting the requirements of a broadcasting environment.

I would like to analyze the customers accommodation availability of the provisional 'smart board,' having specific mode and style, as a circulation platform of digital contents with using a statistic model in order to find a way and means to activate legal circulation of convergence individual products. The smart board means a circulation platform for both users' convenience and copyright protection, by being conveniently able to upload personal convergence digital contents or apply various licence to the uploaded contents according to the purpose of use. Under these premises of the smart board, this paper is going to focus on verifying to find out which factors, such as users' profile attributes, contents using behaviors, awareness of licence and etc, influence on the intention of using the smart board of general users by using a logistic regression model.

Film has been used widely since Auguste and Louis Lumiere hold the first private screening in 1895. Star Wars Episode II: Attack of the Clones directed by George Lucas released on May 16, was the first motion picture both to be shot completely on a high definition digital 24-frame system and to be projected by digital projectors. Its success showed us that the digital cinema era is imminent. Digital Cinema will enable the studios and movie distributors to low the expenses of making and delivering film prints and dissemination of it can put the entire digital cinema ecosystem in great jeopardy. Therefore DRM and other security policies are used for digital cinema content protection. In this paper it will be discussed how the digital cinema platform can package (encooe & encrypt), transport, and project the digital cinema contents safely.

As wireless Internet speads widely, circulation of various types of digital contents become active. Therefore, it is necesary to make a mobile-based DRM (Digatal Rights Management) system to protect digital contents from illegal reproduction and to give proper rights to contents users, In this paper, we present a mibile security system, which protects the copyright for digital contents offered throughout the mobile environment. Our security system is focused on presenting mobile-based DRM architecture. Especially, considering mobile device's decrying power, we adopted partial encryption scheme. For this, wecompared and evaluated the performant of each contents encryption scheme (the entire encryption scheme and the partial encription scheme) and proved that a proper DRM system for current wireless devices is the partial encryption system. Our mobile DRM system can be very efficient to protect contents on the wireless Internet environment.

The use of digital imaging technique and digital contents based on internet has grown rapidly for last several years, and the needs of digital image protection become more important. For the purpose of copyright protection on digital image, the verification of authentication techniques like content authentication, ownership authentication, illegal copy and etc are needs. Digital watermarking, the invisible encryption technique to insert digital watermarking into image, the sophisticated perceptual information should be used for providing transparency and robustness of images on watermarking process. In this paper, we implement the algorithm for preventing forged attack. ownership protection and authentication by transforming the wavelet algorithms in frequency domain in terms of human visual system.

The technique of developing Digital Contents have still not be a standard, and it is cause some problems in the Digital Contents's creating, circulation and consumption, So solve the problem, MPEG suggest MPEG-21 framework. In the standard, The IPMP take charge of the Digital Contents's protection and management, and also it is the same as the rights expression language REL and the dictionary defining the word of REL. But. the study of the IPMP is later than the study of REL and RDD, such as the other study of the MPEG-21 standard. So, there is few system based REL and RDD. In this paper, in order to management and protect contents right. So facing the latest standard, we designed and implementation the Tool Server and the License Server based on REL/RDD.

It is issued that protecting and managing a copyright are very important to a digitization of multimedia content. All of these techniques are for developing solution about protection and management of the copyright and media service. These have been at the head of the growth of the whole media service, but cause problems such as a illegal copy and distribution. To solve these problems, researchers are performing many projects. We analyze the trend of a multimedia service IPMP(Intellectual Property Management and Protection), DMP(Digital Media Project), ENTHRONE(End-to-end Qos through Integrated Management of Content, Networks and Terminals), and DRM(Digital Rights Management).

It requires protection technologies to permit consumer to store a digital broadcasting content and at the same time to protect the intellectual property from illegal action. There is content encryption as one of protection technologies. In this paper, we proposed a protection scheme for digital broadcasting content that broadcasting server. Multiplexes the encryption key into MPEG-2 TS(transport stream) to be able to encrypt received TS at set top box. The proposed method is to modify PMT(program map table) for the information related encryption key and to multiplex key as TS packets. After then the encryption key is extracted from TS stream which is encrypted in set top box.

The wisdom contents consists of an ordinary person's ideas and experience. The Wisdom Market [1] is an online business model where wisdom contents are traded. Thus, the general public could do business activities in the Wisdom Market at ease. As the wisdom contents are themselves the thought of persons, there exists many similar or duplicated contents. Existing copyright protection schemes mainly focus on the primary author's right. Thus, it's not appropriate for protecting the contents of Collective Intelligence that requires to protect the rights of collaborators. There should exist a new method to be dynamic capable of combining and deleting rights of select collaborators. In this study, we propose collective copyright authentication scheme suitable for the contents of Collective Intelligence. The proposed scheme consists of collective copyright registration, addition and verification protocols. It could be applied to various business models that require to combine multiple rights of similar contents or to represent multiple authorships on the same contents.

Recently, the standard work of the copyright of the Digital content is not completed. And the content providers are developing self's copyright protecting technique. here is some problem such as the confusion existed in the copyright protecting and management system. The reason is that the company using different technique when developing the Digital Contents. Now, there is a standard working leaded by the MPEG. It's called MPEG-21 Multimedia framework and the REL is parted of the Intellectual Property Management and Protection included the framework. And the REL's standard working is completed. The Intellectual Property Management and Protection system contain license server, tool server, metadate server and consume server. In this paper, In order to management and protect the Digital Content copyright, We applying the REL, One of the contents of the MPEG-21 framework to design and implementation the License Server manage the settlement and the consumption information and the Tool Server manage and transport the Tools used from Digital Contents formation to the Digital Contents consumption.
