디지털 음악상품의 유료화 서비스를 위해 P2P 서비스 업체들은 콘텐츠를 다운로드 할 때 주는 자와 받는 자간에 포인트를 주고받는 것이 일반화되어 있었다. 그러나 이러한 방식은 다운로드 건별로 사용료를 지급해야 할 권리자와 콘텐츠를 명확하게 연결할 수 있는 콘텐츠 식별 방법이 없는 상태에서 진행되는 것이다. 따라서 명확한 음악식별이 중요한데, 불특정 다수가 제공하는 콘텐츠는 일반적으로 정보가 부정확하고 일관성이 결여되어 있어 해시 기술이나 음악인식 기술 등의 신뢰할 수 있는 콘텐츠 식별 방법을 이용하여 저작권 관리를 하여야 한다. 본 연구에서는 해시 기술 및 콘텐츠 인식 기술을 융합하여 두 기술의 장점만을 활용함으로써 해시 기술의 빠른 속도와 콘텐츠 인식 기술의 편리함을 동시에 제공한다. 이를 바탕으로 저작권 DB 관리 방법, 요금 결제 및 정산 방법 등을 이용하여 P2P 서비스의 유료화를 구현하고자 한다.

In this paper, a research model was designed to investigate the factors affecting the purpose intentions to the online paid knowledge contents in China. The research model includes the contents characteristics, recognition of copyright, recognition of paid, the theory of planned behavior factors. In this research, the data was collected by online survey, and in final analysis, 457 users' questionnaires were used. The empirical paper proves research hypothesis by using SPSS 25.0 and AMOS 23.0. The results of the study are as follows: the contents characteristics partially give positive effects to attitude. In addition, recognition of paid and planning behavior theory factors have positive effects to purpose intentions. This paper provides a useful scheme to promotion the purpose of purchase for paid online knowledge contents.

The core of contents monetization is the consumer's willingness to pay. In the past, the terrestrial contents can be used through the frequency for free. As the terrestrial contents use via online services has been increased, the importance of willingness to pay for the broadcasting contents is getting bigger. To find critical factors which can influence on the willingness to pay for the terrestrial contents, independent factors are categorized into three. The independent factors are users' awareness for copyright protection, contents characteristics, and platform characteristics. The results show that attitude for paying, subjective norms for copyright protection, rapid providing of contents, quality of service, social critical point, and expected service value are found out as significant factors. This result implies that it is necessary to enhance platform competitiveness to survive in convergence environment and customer relationships should be reinforced to maintain them as loyal customers.

The advance of communication and networking technology enables high bandwidth multimedia data transmission. The development of high performance compression technology such as H.264 also encourages high quality video and audio data transmission. The trend requires efficient protection system for digital media rights. We propose an efficient digital media protection system using elliptic curve cryptography. Only key parameters are encrypted to reduce the burden of complex encryption and decryption in the proposed system, and the digital media are not played back or the quality is degraded if the encrypted information is missing. We need a playback system with an ECC processor to implement the proposed system. We implement an H.264 decoding system with a configurable ECC processor to verify the proposed protection system We verify that the H.264 movie is not decoded without the decrypted information.
