본 발명은 P2P 기술 중 Peer To Peer 파일 교환 기술에 속하며 종래 이 분야의 기술은 Napster, 소리바다, Gnutella, Freenet등이 다양한 형태로 기술을 가지고 있으나, DRM과 컨텐츠 신뢰 인덱싱 기술을 이용하여 저작권 문제와 컨텐츠 신뢰 문제를 해결한 것이 본 발명의 획기적인 점이다.The present invention belongs to Peer To Peer file exchange technology among P2P technologies, and the prior art has various technologies such as Napster, Soribada, Gnutella, Freenet, etc. However, copyright issues and contents using DRM and content trust indexing technology Solving the problem of trust is a breakthrough of the present invention.
본 발명은 위의 기술들을 결합하여 새로운 디지털 멀티미디어 컨텐츠사업을 실현하고자 한다.The present invention combines the above techniques to realize a new digital multimedia content business.
본 발명은 저작권 보호를 위하여 DRM 기술을 적용할 것이며, 신뢰성문제를 해결하기 위해 컨텐츠 신뢰 인덱싱 기술을 적용할 것이고, Peer들 간의 원활한 파일교환을 위하여 근접 루트 탐색 기술을 적용할 것이다.The present invention will apply the DRM technology for copyright protection, apply the content trust indexing technology to solve the reliability problem, and apply the proximity root search technology for smooth file exchange between peers.
이를 위해 이루어야 할 기술적 과제는 DRM서버와 인증 패킷 교환이 가능한새로운 멀티미디어 파일 포맷의 제작, 이를 유일하게 재생할 멀티미디어 플레이어의 제작, 인증을 위한 하드웨어 락의 제작, 컨텐츠 신뢰 인덱싱 기술을 위한 데이터 지문 생성 및 인식 툴 제작, 근접루트 탐색을 위한 Traceraut 분석 툴 제작이다.The technical challenges to be achieved are the creation of a new multimedia file format that can exchange authentication packets with a DRM server, the creation of a multimedia player that plays it only, the creation of a hardware lock for authentication, and the generation and recognition of data fingerprints for content trust indexing technology. Build tool, Traceraut analysis tool for near-root search.
..
본 발명은 기본적으로 서칭 서버(10), 컨텐츠 신뢰 인덱싱 서버(20), DRM서버(30) 결제 서버(40), 컨텐츠 서버(50), 저작권보호가 가능한 새로운 멀티미디어 파일 포맷(60), 저작권 보호가 가능한 새로운 멀티미디어 플레이어(70), 하드웨어 키락(80)으로 구성된다.The present invention basically the search server 10, content trust indexing server 20, DRM server 30, payment server 40, content server 50, a new multimedia file format (60), which is copyright protected, copyright protection It is composed of a new multimedia player 70, a hardware key lock 80.
[도1]에서 처럼 하드웨어 락(80)을 장착한 최초의 Peer가 컨텐츠를 서칭 서버에서 검색하여 컨텐츠 제공자가 새로운 멀티미디어 포맷(60)으로 제작하여 컨텐츠 서버(50)에 제공한 파일을 전송 받으면 결제 서버를 통해 컨텐츠의 전송 요금을 지불하고 DRM서버는 이 사용자에 대해 이 파일에 대한 컨텐츠 사용 권한을 인증한다. 동시에 차후 Peer간의 교환을 위하여 서칭 서버에 파일 소유 기록을 등재한다. 컨텐츠를 전송 받은 Peer는 하드웨어 락(80)이 장착된 PC에서 저작권 보호가 가능한 새로운 멀티미디어 플레이어(70)으로 새로운 파일 포맷(60)으로 제작된 컨텐츠를 재생하며 재생 도중 일정지점에서 DRM 서버와 정기적으로 인증 패킷을 교환함으로써 컨텐츠사용권한을 확인한다.As shown in FIG. 1, the first Peer equipped with the hardware lock 80 retrieves the content from the search server, and the content provider makes a payment in the new multimedia format 60 and receives the file provided to the content server 50. You pay for the transfer of content through the server, and the DRM server authenticates the content usage rights to this file for this user. At the same time, the file ownership record is registered on the search server for exchange between peers. Peer received the content is a new multimedia player 70 with copyright protection in a PC equipped with a hardware lock (80) to play the content produced in the new file format (60), and regularly plays with the DRM server at a certain point during playback. The authority to use the content is checked by exchanging authentication packets.
이후 새로운 Peer가 동일한 파일에 대해 서칭서버(10)에 요청하게 되면 [도2] 와 같이 서칭서버(10)는 가장 근접한 컨텐츠 소유 Peer의 어드레스를 새로운Peer에게 제공하고 새로운 Peer는 컨텐츠 서버가 아닌 Peer에게 컨텐츠를 전송 받게 된다. 컨텐츠를 전송하기 전 컨텐츠를 소유한 Peer는 컨텐츠 신뢰 인덱싱 서버(20)에서 최초 전송 받은 컨텐츠에 변형이나 손상이 가지 않았는지 확인 받고 전송을 시작한다. 새로운 Peer는 컨텐츠 전송 금액을 결제서버(40)를 통해서 결제하고 결제서버(40)는 이 금액 중 일부를 컨텐츠를 제공한 Peer에게 환급하며, 동시에 차후 Peer간의 교환을 위하여 서칭 서버에 새로운 Peer의 파일 소유 기록을 등재한다.After that, when a new peer requests the search server 10 for the same file, the search server 10 provides the address of the closest content owning peer to the new peer as shown in FIG. 2, and the new peer is not a content server. You will receive the content. Peer who owns the content before transmitting the content and checks whether there is no deformation or damage to the content initially received from the content trust indexing server 20 and starts the transmission. The new peer pays the content transfer amount through the payment server 40, and the payment server 40 refunds some of this amount to the peer who provided the content, and at the same time, the file of the new peer on the search server for exchange between peers. List ownership records.
이러한 과정을 통하여 멀티미디어 컨텐츠는 기존의 형태에서처럼 네트웍에 심각한 부하를 일으키거나 저장공간의 부족을 일으키지 않으면서 멀티미디어 컨텐츠 사업의 사업성을 실현하고 나아가 이용자들도 금전적인 혜택을 공유할 수 있는 시스템을 구성한다.Through this process, multimedia contents realize the feasibility of the multimedia contents business without causing serious load on the network or lack of storage space as in the conventional form, and constitute a system that allows users to share financial benefits. .
