The present invention relates to a digital content service system and method, and more particularly, to a system and method for providing digital content to a user through a communication network.

With the spread of the Internet, various cultures have been created and spread among Internet users. As one of these phenomena, it is common to see the recent Internet users decorate music to be played on a web page such as a bulletin board. In general, the playback of music on the web page is implemented in a format that includes the address of the sound source file provided by the music service provider in the source file of the web page.

1 is a view for explaining a conventional configuration for playing music in a web page.

In FIG. 1, the sound source service providing server 100, the user terminal 200, and the web server 300 are connected to each other through an internet network 400. In addition, the web server 310, 320 is shown to provide a web page (312, 322) that can play music, respectively.

When the web pages 312 and 322 include the address of the sound source file provided by the sound source service providing server 100, when the user terminals 210 and 220 access the web pages 312 and 322, the user terminal Music included in web pages 312 and 322 is output to 210 and 220.

In general, the sound source service providing server 100 provides a sound source for a fee. Therefore, in order for the user of the first user terminal 210 to include the address of the sound source file in the first webpage 312, the address of the sound source file must be provided from the sound service service providing server 100 at a fee.

However, since the address of the sound source file included in the web page can be easily confirmed by using a function such as viewing the source of the web browser, the user of the second user terminal 220 may use the sound source file from the sound source service providing server 100. Even without the address, the address of the sound source file included in the first web page can be copied and included in the source code of the second web page.

In the related art, a sound source is unfairly used in a state in which a fair price is not paid. Thus, the rights of a sound source copyright holder are seriously infringed.

Disclosure of Invention The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an online content service system and method that can protect the rights of a content copyright holder by preventing the illegal use of content on the Internet.

In order to achieve the above object, the online content service system according to the present invention includes a content providing unit, an authentication information storage unit, and a content storage unit. The content providing unit includes content when the content request information matches the pre-stored authentication information when receiving the content request information including the address information of the web page requesting the desired content and the content information corresponding to the content from the user terminal. The content response information is transmitted to the user terminal. The content storage unit stores the content, and the authentication information storage unit stores the authentication information.

Since the content is provided after the authentication procedure is performed using the address information of the web page requesting the content, it is possible to prevent the content from being unfairly used in the web page not registered in the authentication information.

The content request information may be transmitted by a user program on a user terminal driven by a server program on a content providing unit, and the server program may be driven by an address of a server program registered on a web page.

Since the address of the computer program for accessing the content file is included on the web page, not the address of the content file, even when the source code of the web page is checked, the address of the content file cannot be known.

To this end, when the content providing unit receives a request for purchasing content from the user terminal, the content providing unit may generate a server program corresponding to the content and provide the user with the address of the server program.

The web page should include the address of a server program for accessing the content file, which is generated and provided to the user when the user purchases the content.

Content information may include information of the user, and the content purchase time information. The content purchased by the user may be specified by the user and the time when the user purchased the content.

The server program may be a flash file, and the name of the flash file may be code that encrypts content information. Also, the user program is an ActiveX program, and the flash file may generate middleware that relays between the flash file and the ActiveX program.

The content response information may include an address of the content, and may include a sound source identifier or a decryption key to be delivered to the DRM player in addition to the content address.

In addition, the invention which implements the system invention in the form of a method is claimed together.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a schematic block diagram illustrating an embodiment of an online content service system according to the present invention.

In FIG. 2, the content providing server 500, the user terminal 600, and the web server 700 are connected to each other through an internet network 800. The content providing server 500 includes a content providing unit 510, an authentication information storage unit 520, and a content storage unit 530. The web server 700 includes a web page 702 on which content can be played. ).

The content played in the user terminal 600 is generally music content, but any type of content that may be played such as a still image or a video may be applied.

The user terminal 600 accesses a website provided by the content providing server 500 and requests a link generation for playing a desired content through a payment process.

When the content providing unit 510 receives a link generation request from the user terminal 600, the content providing unit 510 generates a flash file corresponding to the requested content, and the address (URL) of the flash file generated by the user terminal 600. ). At this time, the file name of the flash file is generated by an encrypted code having user information and link generation time information, and is a unique file name distinguished from the file name of other files.

The user terminal 600 copies and attaches the URL of the received flash file to the web page 702. Thereafter, when the user terminal 600 accesses the web page 702, the flash file is executed to store the authentication information in the authentication information storage unit 520, and the authentication procedure is performed.

Flash is Macromedia's web animation authoring tool that enables fast animations on web pages, with minimal file size, excellent animation features, and streaming technology.

As such, since the address of the computer program for accessing the content file is included on the web page, the address of the content file cannot be known even if the source code of the web page is checked. By using a flash file it is possible to perform a good operation with a small capacity.

The process of storing the authentication information and performing the authentication procedure will be described in more detail with reference to FIG. 3 below.

3 is a schematic block diagram of a user terminal and a content providing system of FIG. 2.

When the flash player 610 is executed, the flash player 610 generates the middleware 620 implemented in JavaScript in real time, and the file name and the webpage of the flash file 610 as the generated middleware 620. Pass the URL (referer) of 702. The file name of the flash player 610 and the URL of the web page 702 constitute an authentication key value.

A script is a set of statements that are translated and executed by a program other than a computer processor or compiler. A script is a short program or instruction written in a language other than a programming language.

In addition, middleware refers to software that connects servers and clients of different types in a distributed computing environment. In the present invention, the middleware plays a role of connecting the flash file and the ActiveX.

The middleware 620 transmits the received authentication key value to the authentication ActiveX 630. In the first connection to the content providing server 500 by the flash player 610, the authentication ActiveX 630 transmits the received authentication key value to the content providing server 500. The transmitted authentication key value is stored in the authentication information storage unit 520 as authentication information and the authentication information storing procedure is terminated.

Here, ActiveX is a technology provided to connect general applications with the web, and plays a role of connecting various general applications written in different characters and websites.

After the authentication information is stored, when the flash player 610 is executed, the authentication ActiveX 630 transmits the received authentication key value to the content providing server 500, and the content providing unit 510 receives the received authentication key value. And the stored authentication information is compared to determine whether to approve the authentication.

If the authentication fails because the received authentication key value and the stored authentication information do not coincide with each other, the authentication procedure is terminated. On the contrary, when the authentication is successfully performed because the received authentication key value and the stored authentication information match each other, the content provider 510 may request an identifier (ID) of the requested content, a URL of the content file, and a DRM player. The decryption key is encrypted and transmitted to the authentication ActiveX 630, and the authentication ActiveX 630 transmits the decryption key to the middleware 620 again.

The middleware 620 transfers the received information to the playback ActiveX 640 serving as a DRM player, and the playback ActiveX 640 decodes it and executes the received content identifier and content URL. Play it.

Here, DRM refers to technologies and services that protect the interests and rights of copyright-related parties by preventing unauthorized use of digital content, and stands for Digital Rights Management. DRM is a technology that protects the rights and interests of content providers, prevents illegal copying, supports the creation, distribution and management of contents such as charging royalties and payments.

The function of each module of the user terminal 600 is summarized as follows.

The flash player 610 is responsible for an external interface and generates middleware in real time. Also, the authentication key value and the play / stop command are transmitted to the middleware.

The middleware 620 generates an ActiveX installation code and transmits an authentication key value and a play / stop command to the authentication ActiveX 630.

The authentication ActiveX 630 performs an authentication procedure with the content providing server 500 using the authentication key value. In the case of a link not registered, a referer is registered and the content identifier and decryption key value obtained after authentication are transmitted to the middleware 620.

The playback ActiveX 640 plays the role of a DRM player that plays content using the content identifier and decryption key received from the middleware 620 and performs a play / stop function according to the command of the middleware 620. .

Here, the authentication ActiveX 630 and the playback ActiveX 640 may be implemented in one ActiveX file.

4 is a schematic flowchart illustrating an embodiment of an online content service method according to the present invention.

First, a link generation request of a desired digital media content is input from a user (S110). Subsequently, it is determined whether the user has completed the payment process (S120). When the payment process is completed, a flash file having an encrypted code having user information and link generation time information as a file name is generated (S130).

When the user attaches the flash file URL to a desired post on the Internet, the flash file is executed and at the same time, the file name of the flash file constituting the authentication key value and the URL of the created post are transmitted (S140).

When the authentication key value is transmitted, it is determined whether the transmission of the authentication key value is the first transmission (S150), and in the case of the first transmission, the transmitted authentication key value is stored as authentication information (S160), and when it is not the first transmission, It is determined whether the authentication key value matches the stored authentication information (S170), and only if it matches, the URL of the desired content, the identifier of the content, and the decryption key required to drive the DRM player are transmitted to play the content (S180). .

Since the present invention provides the content after performing the authentication procedure using the address information of the web page requesting the content, it is possible to prevent the unfair use of the content on the web page not registered in the authentication information, and thus, the content The rights of the copyright holder can be protected.

Although the invention has been described in terms of some preferred embodiments, the scope of the invention should not be limited thereby, but should be construed as a further refinement or modification of the embodiments supported by the claims.
