The present invention relates to a method and apparatus for protecting original content in a streaming service of multimedia paid content.

Currently, multimedia videos or music are being streamed through many Internet sites, and many of them are paid contents that are expensive and time-consuming to produce. There is a need for measures to protect content producers and content service providers by preventing unauthorized use that may occur when these contents are serviced through the Internet, and by providing services centered on legitimate users.

Since multimedia contents are often large, it takes a lot of time to transmit the entire file, so a large number of multimedia contents are provided in the form of streaming that is played during transmission. The streaming service is a transmission service in which content files are divided into pieces, transmitted in order according to the playback order, received by the receiving party, and played immediately. This streaming service is initiated by a content request to the streaming server on the service provider side. When the request is made according to the server's content address and transport protocol, the service is enabled. It is to be done.

Currently, the streaming service for music or video on the Internet is made by direct location information on the content. The location of the multimedia file within the web page is designated as a link, and the user clicks the link and clicks the link. By providing the service by playing, if the location information of the paid multimedia contents is exposed in addition to the legitimate user, the file can be unfairly accessed. Furthermore, the file is exposed to other users, thereby exposing a great damage to the content owner. to be.

This process is described in more detail as follows. For example, if the 'music.mp3' file on the xx.xx.xx.xx site is exposed to users on an illegal site, the 'http: //xx.xx' .xx.xx / music.mp3 'can be inserted into the website's web page. In the above manner, multimedia files such as mp3, wma, and asf are clicked on the homepage's link to be played by the player (MS Media Player, WinAmp, etc.) on the user's computer. This method requires a program that can be played separately from the corresponding web page so that the file to be transmitted can be played immediately.

Similarly, in the case of a link through a media server, simply linking the streaming multimedia link address (mms: // ～~~) using the streaming protocol directly to the homepage, the user has to click on the link (MS MediaPlayer). , WinAmp, etc.) You can easily stream files in wma or asf to MMS protocol. This method is characterized by the need for a program that can play streaming music using the ActiveX control provided by Windows or using a separate MMS protocol so that music can be transmitted immediately.

Without accessing the original multimedia file directly, the media server can be accessed using an asx file containing the location information. The asx file is a file for the playlist of the content files such as mms and wma at a specific address in the server. This allows access to multiple multimedia files in addition to individual content.

Since these approaches are not originally considered to be paid, there is a disadvantage in that it is impossible to determine whether a request for a corresponding content file is justified, and there is a disadvantage in that service information is exposed as it is.

The present invention relates to an apparatus and a method for a streaming service of paid multimedia content as described above, and does not directly expose information about the content to the user, but prior to the user's request before the content is transmitted It is an object of the present invention to provide a method for determining the validity of and a device implementing the same.

In the present invention, unlike requesting stream data directly from a content service provider, and receiving and playing the stream data, the user purchases a right to use multimedia content and receives a secured link URL for the corresponding content. It is intended to be able to provide multimedia services to visitors by inserting into the. The asx file is used to transfer the asx file containing the storage address list of the file to be played by the user's real-time request. The server receives the asx file, which is the file list file from the server, and the user computer receives the contents of the asx file. By requesting transmission, the content is received and played. This method has the disadvantage that anyone can request and receive the presented asx file, receive and play the content, and copy and take the link so that an unspecified user can use the original content indefinitely.

Accordingly, an object of the present invention is to enable a user to easily check the user's right to the corresponding content based on information about the user, and to prevent unauthorized use of the original content, based on the user's request for the content. It comprises a right authentication step, and hiding the information about the original content file transmitted to transmit the content file for the authenticated user request.

The present invention allows content playback to be started using an asx file containing a list of content files to be played. This is not a way that the asx file is inserted into the bulletin board page 20 in the form of a link. In (20), a link URL to the authentication processing unit 13, which is a server application of the content service server 11 instead of the asx file address, is inserted, and the authentication processing unit 13 is operated by this link URL, so that The request is verified and the asx file for the corresponding content is generated only for the verified content request, and is transmitted to the user's computer to transmit the content.

At this time, when the content request to the authentication processing unit 13, the content request authentication module 14 by verifying that the user's authentication key is justified by verifying that the request for authentication of the request is generated asx file generation The module 15 generates an asx file for the corresponding content and sends it to the user computer 19.

The insertion of the content request link URL into the web page to the authentication processing unit 13 may be illustrated as follows. In the user web page 20, "<embedded src = link URL>", "<a href=link URL> Or a link URL to the authentication processing unit 13, which is a server application of the content service server 11, is inserted and exposed through another user's separate tag.

To this end, the device of the present invention is a secure link URL generation unit 12 for generating a link URL including an authentication key for authenticating the rights of the customer when the purchase of paid content occurs, and the user computer 19 An authentication processing unit 13 including a content request authentication module 14 for authenticating a content transmission request from the server, an asx file generation module 15 for generating an asx file for the corresponding content, and stream data of the corresponding content; It consists of a media server 16. 1 is a block diagram of a security processing apparatus for transmitting a request for paying multimedia contents according to the present invention.

The user who wants to connect the content to his or her bulletin board or blog and purchases the content from the service provider's content service server 11 and secured the link URL for the corresponding content generated by the secure link URL generation unit 12 This link is a link to the authentication processing unit 13, which is a server program installed in the content service server 11, and a content designation code and a variable to be passed to the authentication processing unit 13 when the authentication processing unit 13 is called. Characterized by the code for the authentication key for the content. An example of such a link URL is as follows.

http://server1.mmbox.com/link_cert.asp?sid=359750&code=01048957D464C03C5

The illustrated link URL calls the server program 12 running on the content service server 11 and passes the SID and code as variables. sid means a code (359750) for designating content, and code is an authentication key (01048957D464C03C5) for authenticating the request, and is composed of content purchaser information for a corresponding URL and purchase conditions such as a pay-per-use or a term-based service. The authentication key is generated by encrypting a combination of purchase conditions such as a purchaser ID from the customer DB 17 and a use period or usage when generating a link according to content purchase, and this generating method is outside the scope of the present invention. It is excluded from the configuration.

For the content transmission request by the secured content link URL from the user computer 19, the authentication processing unit 13 of the content service server 11 analyzes the content request authentication key and considers the justification of the corresponding authentication key and purchase conditions. The validity of the request is verified, and an asx file for the corresponding content is generated according to the purchase condition and transmitted to the user computer 19 through the network.

2 is a flowchart of a method for authenticating a secure processing link URL of paid multimedia contents according to the present invention, which is inserted into a bulletin board page 20 downloaded to a user's computer 19 when a user uses a buyer's bulletin board. When the content service server 11 is requested to transmit the content through the processed link URL, the content service server 11 transmits the asx file through the following steps.

The first step (S21) is to check the check sum of the authentication key of the variable for the content request from the user computer 19 to determine whether it is a valid authentication key, the operation for generating an asx file for the valid authentication key Continue or generate an authentication key error page.

Step 2 (S22) verifies whether the link expiration period included in the authentication key has been exceeded, and if the expiration period is exceeded, a trial period expiration guide page is generated.

Step 3 (S23) is a step of verifying whether the link purchased by the customer is valid. The customer DB 17 and the content DB 18 are searched for the content and user information to be linked, and the requested customer information and content information are requested. Is valid and generates an error page if the request is invalid.

Step 4 (S24) stores the usage history, such as the link usage log and the user-related IP address log.

Step 5 (S25) generates an asx file for transmitting and playing the content.

Step 6 (S26) transmits the web page or file generated in the authentication process to the customer.

The present invention provides a content that allows a customer who pays a certain price for multimedia content to receive a link to the content from a service provider and insert it into his or her bulletin board or blog to provide streaming service to users who use their bulletin board. In the method, it is characterized in that configured to prevent unauthorized use of the content by unauthorized users by securely processing the content link URL when the content request.

The present invention inserts a link URL for the content on a web page such as a homepage, a bulletin board, or a blog, and a customer pays for the content, and streams his or her own stream to users connected by accessing arbitrary users. In the provision of the service, the link URL can be secured so that the content transmission request from the user's computer 19 can verify whether the authorized link URL is used. It can prevent damage such as additional network load due to transmission. Looking at the effects of the invention in detail as follows.

First, only paid members who have paid a certain price for the content are suitable to service the paid content by creating and providing a secured link that can receive the corresponding content by streaming service.
