본 발명은 인터넷이나 통신망 상에서 저작권자의 권리를 보다 확실하게 보호하는 기술에 관한 것으로, 특히 퍼블릭키이와 프라이베이트 키이를 이용하여 사용자를 인증하고 인터넷이나 통신망 상에서 그 인증된 사용자에 한하여 멀티미디어 콘텐츠를 제공받을 수 있도록한 멀티미디어 전송시스템의 저작권 보호 장치 및 방법에 관한 것이다. The present invention relates to a technology that more reliably protect the copyright holder's rights over the Internet or a communication network, in particular a public key The fryer bait key using it authenticates the user and receive multimedia content only to the authorized users on the Internet or a communication network It will be one of the copyright protection system and method of multimedia transmission systems to.

종래기술에 의한 멀티미디어 전송 시스템에 있어서는 사용자를 인증하는 기술이 확립되어 있지 않아 인터넷이나 통신망 상에서 유통되는 MPEG 파일이나 MP3 파일등이 저작권자의 허락없이 불법적으로 유출되는 경우가 빈번히 발생되었다. It was often occurs when the prior art is in the multimedia transmission system according to the technique does not been established a technique for authenticating a user such as an MPEG file or MP3 file distributed over the Internet or network illegally leaked without permission of the copyright holder.

이와 같이 종래기술에 의한 종래기술에 의한 멀티미디어 전송 시스템에 있어서는 합법적으로 사용자를 인증하는 기술이 확립되어 있지 않아 저작권자의 권리를 확실하게 보호할 수 없게 되고, 이로인하여 인터넷이나 통신망 상에서 건전한 상거래 문화를 정착시키는데 어려움이 있었다. Thus, in the multimedia transmission system according to the prior art, according to the prior art it is not legal because there is no established technique to authenticate a user can reliably protect the copyright holder's rights, which results establish a sound commerce culture on the Internet or network sikineunde was difficult.

따라서, 본 발명이 이루고자 하는 기술적 과제는 퍼블릭 키이(Public Key)와 프라이베이트 키이(Private Key)를 이용하여 합법적인 사용자를 인증하고, 그 인증된 사용자가 요구하는 멀티미디어 콘텐츠(예: MP3파일)가 통신망 상에서 불법적으로 유출되는 것을 방지하는 멀티미디어 전송시스템의 저작권 보호 장치 및 방법을 제공함에 있다. Accordingly, the object of the present invention is the public key (Public Key) and fry bait using a key (Private Key), and authenticates the legitimate user, the authenticated multimedia content requested by the user (such as MP3 files) to provide a copyright protection system and a method of multimedia transmission systems to prevent the illegal outflow over the communication network.

도 1은 본 발명의 목적을 달성하기 위한 멀티미디어 전송시스템의 저작권 보호장치의 일실시 예시 블록도로서 이에 도시한 바와 같이, 저작권자 데이터베이스(12)에 구매사실을 통보함과 아울러 자체적으로 구매상황을 관리하고, 저작권자 권리보호를 위해 프라이베이트 키이를 관리하는 뮤직아이 서버(MUSIC-i Server)(11)와; 1 is managing the purchase situation as well as its own and must inform the purchase fact the copyright database 12 as shown in this illustrated as an exemplary illustrative block diagram of a copyright protection system for the multimedia transmission system to achieve the object of the present invention; and kids and music server (MUSIC-i server) (11) to manage them fry bait keys for copyright protection of rights; 사용자 클라이언트(15)로부터 구매요구가 있을 때 상기 뮤직아이 서버(11)로부터 사용자 인증과 함께 프라이베이트 키이를 부여받은 후, 뮤직 데이터베이스(14)로부터 읽어온 해당 뮤직파일과 함께 그 프라이베이트 키이를 암호화 처리하여 다운로드하는 뮤직아이 클라이언트(MUSIC-i Client)(13)와; When a purchase request from the user client 15, the music kids after Fry Beit key grant it with the user authentication from the server (11), and music that Fry Beit key it encrypted with that read from the database (14) music files Music child client (MUSIC-i client) (13) for downloading to the processing; 상기 뮤직아이 클라이언트(13)로부터 공급받은 소프트웨어 형태의 플레이어와, 퍼블릭키이와 쌍을 이루는 프라이베이트 키이를 이용하여 그 뮤직아이 클라이언트(13)로부터 다운로드받은 뮤직파일(예: MP3파일)을 재생출력하거나, 다시 휴대형 플레이어측으로 다운로드하는 사용자 클라이언트(15)로 구성한 것으로, 이와 같이 구성한 본 발명의 작용을 첨부한 도 2를 참조하여 상세히 설명하면 다음과 같다. And the music child of the software type that received from the client 13 player, constituting the public key this pair fry bait key by using this, that music child downloaded music files from the client 13: the Play back (for example MP3 files), or , again be configured to the user client 15 to download the side of the portable player, it will be described in detail with reference to FIG. 2 accompanying the operation of the present invention constructed as described immediately above as follows.

사용자 클라이언트(15)가 합법적으로 파일을 공급받기 위해서는 인증을 받아야 한다. To get your client (15) is lawfully supplied files must be certified. 이를 위해 뮤직아이 클라이언트(13)는 뮤직아이 서버(11)측으로부터 사용자 인증을 받고, 이때 그 뮤직아이 서버(11)로부터 퍼블릭 키이와, 그 퍼블릭 키이와 쌍을 이루는 프라이베이트 키이(Pr_key)를 공급받는다. For this purpose, music child client 13 receives the user authentication from the music child server 11 side, wherein the music public key this way from the child server 11, the public key, this pair to supply the fry bait key (Pr_key) forming receive.

또한, 상기 뮤직아이 클라이언트(13)는 사용자 클라이언트(15)가 요구한 뮤직파일을 뮤직 데이터베이스(14)로부터 읽어온 다음 소프트웨어 플레이어와 함께 퍼블릭 키이(Pr_key)로 함호화 하여 그 사용자 클라이언트(15)측으로 다운로드 한다. Also, toward the music kids client 13 user client (15) to the luxury box of a music file requirement as a music database (14), public key (Pr_key) with read on the following software player from the user client (15) Download. 이때, 상기 프라이베이트 키이(Pr_key)는 상기 소프트웨어 플레이어에 삽입하여 다운로드하게 되며, 필요에 따라 별도로 다운로드할 수도 있다. In this case, the Fry bait key (Pr_key) is downloaded to the software inserted in the player, and may be downloaded separately, if necessary.

사용자 클라이언트(15)는 상기 뮤직아이 클라이언트(13)로부터 다운로드 받은 소프트웨어 플레이어를 상기 프라이베이트 키이(Pr_key)로 해독하여 목적한 뮤직파일의 음악을 감상할 수 있게 된다. User client 15 is able to listen to music of one music file, and the purpose of the software, players who download music from the child client 13 decrypts the key fry bait (Pr_key).

상기 사용자 클라이언트(15)의 일실시예로써 개인용 컴퓨터(PC)를 들 수 있는데, 이의 작용을 도 2를 참조하여 좀더 상세히 설명하면 다음과 같다. There can be mentioned a personal computer (PC) as an embodiment of the user client 15, if in more detail described with reference to Figure 2 the operation thereof follows.

피씨(22)는 인터넷(21)을 통해 상기 뮤직아이 클라이언트(13)로부터 상기의 설명에서와 같이 소프트웨어 플레이어(26)를 공급받는다. PC 22 is supplied with the software player 26, as shown in the above description from the music child client 13 via the Internet 21. 그 소프트웨어 플레이어(26)에서 MCP(MCP:Multimedia Copyright Protection) 디코더(26A)는 프라이베이트 키이(Pr_key)를 이용하여 MP3 파일(26B)를 복원하고, 그 복원된 MP3 파일(26B)이 MP3 디코더(26C)를 통해 원래의 음악파일로 복원된다. In the software player (26) MCP (MCP: Multimedia Copyright Protection) decoder (26A) is Fry restore bait key MP3 files (26B) using (Pr_key), and that the restored MP3 files (26B), the MP3 decoder ( through 26C) and restored to the original music file. 따라서, 사용자는 자기가 요청한 뮤직파일을 피씨(22)를 통해 감상할 수 있게 된다. Thus, the user is requested so he can listen to music files through a PC (22).

한편, 상기 피씨(22)에서 휴대형 플레이어(23)측으로 다운로드할 때 내부의 암호화기(24A)를 이용하여 멀티미디어 콘텐츠 예를 들어 뮤직파일을 암호화 처리하여 다운로드하게 되며, 반대로 그 휴대형 플레이어(23)로부터 업로딩되는 뮤직파일은 해독기(24B)를 통해 해독한 후 MCP 미디어(25) 및 소프트웨어 플레이어(26)를 통해 재생출력하게 된다. On the other hand, the using the PC 22, encryptor (24A) inside when downloading the side of the portable player 23 from and containing the downloaded cryptographic processing music files of multimedia content such as contrast, from the portable player 23 decoded music file to be uploaded through a decoder (24B) is then reproduced and output through the MCP media 25 and a software player (26).

이상에서 상세히 설명한 바와 같이, 본 발명은 퍼블릭 키이와 프라이베이트 키이를 이용하여 합법적인 사용자를 인증하고, 그 인증된 사용자가 요구한 멀티미디어 콘텐츠를 그 프라이베이트 키이를 이용하여 재생출력할 수 있게 함으로써 저작권자의 권리를 확실하게 보호할 수 있는 효과가 있다. As described above, the present invention is the public key The fryer bait key using this to authenticate a legitimate user, the authenticated user requests multimedia content copyright holder by allowing the Play back to the fryer bait key using this there is the effect that can be reliably protected rights.
