본 논문은 P2P(Peer-To-Peer) 환경이 가지는 장점과 DRM(Digital Rights Management) 기술이 가지는 장점을 결합하여, 서비스에 참여하는 사용자가 합법적으로 컨텐츠를 재판매 할 수 있는 방법을 제공 함으로써 컨텐츠 유통을 활성화 하는 방안을 제시한다. 사용자가 중앙 서버에서 구매한 컨텐츠나 이웃 피어(Peer)에게 구매한 컨텐츠를 재판매 할 경우, 실행권한 라이선스(Rights)를 중앙 서버의 권한 발급기(Rights Issuer)가 아닌, 판매하는 피어 측에서 권한을 위임 받아 직접 발급한다. 컨텐츠를 구매하면 결재가 진행되고, 해당 이익금은 판매한 피어와 해당 컨텐츠를 구매하기까지 참여한 피어의 경로를 분석하여 이익이 재분배 된다. 이러한 이익금 재분배 과정을 통해 합법적인 컨텐츠 유통의 활성화를 기대할 수 있고, P2P 네트워크 환경이 가지는 여러 장점과 DRM 기술의 장점을 융합하여 저비용의 신뢰할 수 있는 시스템 구축이 가능할 것으로 예상된다.

The study of the compatibility of EPUB DRM, granted by the Korea Copyright Commission, as a CT R & D project (Project Title: Development of standard reference software technology for the International Standard EPUB-based eBook DRM) developed standards such as profile standards for encryption, digital signature and authentication certificates and standards for technical terms of rights information. In 2012, these four standards have been established as the Korean Industrial Standards under the names of 'Encryption specification for EPUB DRM', 'the Digital signature specification for EPUB DRM', 'the Certificate specification for EPUB DRM', and 'Definitions of Right Terms for EPUB DRM' through the ODPF(Open Digital Standardization Forum) and the TTA(Telecommunications Technology Association). In spite of the establishment of the eBook DRM standards, however, the absence of the standard technology which supports the compatibility for issues and changes of licenses makes it unable to use eBooks served by different eBook distributors. This study tries to investigate technological approaches to methods of license issues supporting eBook DRM compatibility on the basis of the above-mentioned four EPUB DRM standards and to provide an industrially accepted technological model.

본 라이선스 통합관리시스템은 사용자에게는 소프트웨어 라이선스의 간편한 인증 요청과 재인증 절차를 제공하고 라이선스 발급하고 인증하는 관리자는 사용자의 현황 파악이 가능하며 언제 어디서나 간편하게 라이선스를 제공하여 많은 시간을 단축하고 라이선스 관리 비용을 절감한다. 효율적인 소프트웨어 인증관리시스템의 개발로 소프트웨어 불법적인 사용을 방지하여 건전한 생태계를 조성할 수 있다.

ePUB is one of the most pervasive eBook formats since it was announced as a 2009 standard in IDPF(International Digital Publishing Forum). ePUB is compressed as a ZIP Archive format and structured as a standard format of OCF. Domestically and internationally, eBook services applying DRM into ePUB have currently been active, while it does not satisfy various needs from business because it does not support preview service which is due to the encryption of the whole ePUB as a single key. This study suggests a way to apply diverse business models by providing eBook content based on ePUB multiple key encryption method, not by encrypting it simply as a single key. The encryption method which applies a multiple key encryption method is suggested as a practically appliable form together with licence issuing and delivery method and decryption method in eBook readers. The multiple key encryption method suggested in this study will make it possible to support partial preview services of ePUB based eBook content. It will be applied to diverse service models and enhance the security level better then single key based encryption method.
