The present invention relates to a network-based paid content integrated management method and a system thereof, and more particularly, to a network-based convenient content management of a content distributor and a content distributor according to various systems for driving content within a legitimate scope. It relates to an integrated content management method and system.

In general, the transmission and reception of information based on a network is performed through a web site, which is a collection of web files on a particular subject including a start file called a home page.

These sites are divided into various types according to their purpose. For example, portal sites are the first or most frequently staying sites when users access the web.

Representative services provided by portal sites include website directory services, such as search engines for other sites, news, weather information, e-mail, securities, stock trading, telephone numbers, and map information. And sometimes even the role of community information plazas.

On the other hand, sites that are linked by a website directory service and provide only specific information or services that portal sites cannot provide are being developed one after another, and as a site for providing information on various e-commerce sites or specific purposes, for example, As paid content, sites that specialize in only video files for music files or movies have been developed.

Such a specific purpose website and the information (content) providing system through this has the advantage of providing more content according to the construction of more faithful data for any specific field, the user (client) through the desired content There is an advantage that the supplier can generate a profit through this, and if such content is paid, the advantage of e-commerce can be seen.

However, the distribution of copyrighted works (contents) is a problem in the electronic commerce, which is a form of distribution of the copyrighted works in the past was distributed in large quantities, distributed offline and the end user obtained and used it, but the network is a copyrighted work This is because the creators and end-users of the company can directly connect the content distributors and users (clients) across the walls of places and time media.

In particular, MP3 technology is used as a means of mass transfer of music works in conjunction with the Internet, and music works can be quickly and mass-produced on the Internet by compressing music works on the Internet as well as music works on CDs into MP3 files. Opportunities and possibilities for unauthorized copying, such as copyright infringement, are increasing.

Due to the need for copyright protection technology to block such indiscriminate copying distribution, a management system for profit distribution of copyright holders, producers, owners, etc. is required, which is one of the representative security techniques for protecting digital contents. A technology called Digital Rights Management (DRM) has been introduced that regulates the right to use digital content as information coupled to.

There are various business models according to the environment. Participants are divided into content creators, content providers, content distributors, copyright holders, content ID granting systems or unique number issuers, intellectual property databases, and users.

Broadly speaking, there are content creators including copyright holders and content distributors who have a right to distribute them, and the content distributors supply contents to users in conjunction with the DRM system in a paid system, and the playback means (browser) , The portable player) is restricted in the use of the content according to the DRM.

The functions of DRM can be divided into the protection of digital contents, management of usage rules, and management of billing system. Different companies with DRM technology are developing technologies using different methods.

As described above, digital contents are protected by encryption process to prevent illegal distribution or illegal use of contents in all processes from creation to distribution, use, and disposal. Only the user can decrypt and use the encrypted contents, and protect the contents by preventing them from being used without a key even if it is illegally distributed.

On the other hand, from the user's point of view, MP3 files as contents, for example music contents, are distributed in a new structure of communication and the Internet, and are merely media containing music information, such as existing CDs, rather than new recording types. In a position that recognizes its own value, it does not place its meaning in the medium or means of playing such content.

That is, in a music file, which is one content, it can be played in a browser in a streaming manner, or a downloaded one can be played in a browser. For a piece of content, this means a great meaning as to whether it is a streaming method or a download method. In addition, the company reserves the right to use the contents within the valid use range paid for.

In addition, it is possible to play what has been downloaded to the portable player via the network, and as a result, it is being adapted to the ubiquitous environment of connecting to the network from time to time to retrieve and use the content desired by the IT technology.

However, in the situation where the DRM method is not standardized, there is a problem in that the management of the paid content, in particular, the paid content management and the user (client) use of the content distributor are inconvenient in the transmission and reproduction of the paid content through the network.

In more detail, apart from the relationship (contract) with the copyright holder or the content creator in the participating entity of the DRM environment, the transaction of the content in the server / client system provides content to the user (client) and the user. I'm a content distributor.

The user pays a price to the content distributor and has a right to use any one of the content, including the activation of the browser as described above for the paid content and the transmission of the content to the portable player and its playback.

Accordingly, the content distributor should perform management to guarantee the user's legitimate scope of use for any one content.

By way of example, assume that one user purchases a music file through a server / client system and plays it in his / her browser.

The purchase is performed by a general e-commerce payment system such as credit card mobile payment, and the user downloads any one music file through the browser.

At this time, the user can connect the computer and the portable player through the terminal not only to play in the browser but also to transfer music files to the portable player of the user, but in this case, the encryption key is activated by the DRM. You cannot play music files.

Accordingly, the user again connects to the system (content distributor) via the network, and tries to download the music file to the portable player.

However, if the buyer and the content purchased by the buyer are not managed in the database by the system company, for example, if the purchase is simply performed for any one content without administration of the user database through login, the buyer is responsible for the content. Repurchase must be performed to download to the portable player.

On the other hand, even if a number of downloads are allowed through membership management, there are a number of devices (players) that play music files, and each of them is applied to each DRM, and each home appliance MP3 player has a different DRM system. And lacks compatibility with each other, so it can only be played on players that match the file.

As a result, the user must check the device (player) possessed by the user prior to the selection of the desired content, and then select the desired content accordingly.

In other words, the existing paid content management is not considered enough by the user (buyer), in particular, the user checks the device (player) possessed before the selection of the content desired by the user, and then according to the content desired by the user If you do not have any content applied to the device, the situation is spreading to the audience that it is impossible to use.

Furthermore, the purchase of content is related to the use of the content itself, and it is unreasonable to be bound to the device that plays the content, and it is arbitrary for the user to use it for any purchased content. In addition, as the user can have a plurality of devices of different models (for example, a dedicated player, a mobile with a player function), it is also arbitrary for the user to change the player to use arbitrarily. This is inconvenient to change the interface in the browser each time.

As a result, the management of network-based paid content up to now has been focused on security and encryption as a means of preventing illegal copying, and even at an advanced stage, DRM, which is being developed, has developed a content identification, secure transaction, and protection for copyright management. It is known as a management technology related only to the protection of contents such as monitoring, monitoring, and tracking.

Accordingly, the user's point of view is that the use of the content, even if the legitimate use range is quite inconvenient, and the management of the conventional paid content is an uncomfortable system in which the user is adapted to the ubiquitous environment as described above Eventually, it is rejected by the user, and it is a fatal factor that can be intuitively seen as a drop in revenue from the position of the content distributor who wants to generate revenue.

Accordingly, the present invention has been made to improve the above problems, the network-based paid content management method and the convenience of the user to use the paid content and the content distributor of the content distribution in accordance with various operation means using the content within the legitimate scope and its The purpose is to provide a system.

To this end, the present invention manages paid content as a server / client system, authenticates a user on the premise of login, and then forms a database according to the user to manage paid content.

In other words, the logged-in user connected to the system checks the paid content purchased through his database, accesses the database, and uses his paid content.

Once the database is established in the system for the purchased content, the user can freely use the paid content in the legitimate scope of use defined by DRM, especially the interface provided from the server / client system when connecting to the portable player. Through the content transmission to the portable player, the interface recognizes the DRM of the portable player connected to the browser, and accordingly to transmit the content containing the DRM from the database.

Hereinafter, the present invention with reference to the accompanying drawings in detail as follows.

Exemplary Drawings Figure 1 is a block diagram showing a paid content management system according to the present invention, Figure 2 is a block diagram showing a content delivery system for transmitting content in accordance with the various players in the paid content management system according to the present invention.

3 is a flowchart illustrating a paid content management method according to the present invention. [0038] FIG. 4 is an exemplary view showing an operation window as a GUI (graphical user interface) provided in a content management system according to the present invention.

The present invention provides a login step in which a user accesses a system on a premise that a user logs in to form a relational database with content purchased by a user in a server / client system through a network:

When the logged-in user purchases the content, the content database of the purchased content and the member database of the user are formed as a relational database as the relational database, and the browser is purchased through the operation window which is an interface to the logged-in user. Formation of purchase content that displays a list of content:

The browser recognizes the DRM format requested by the player connected to the user browser and activates the purchase content requested by the user from the list of purchase contents displayed through the operation window, and the content specified through the operation window. The browser is a network-based paid content integrated management method comprising the purchase content using step of transmitting to the player according to the content containing the DRM requested by the player from the content database.

In the purchase content use step, the activation of the purchase content through the operation window arranges the play mode adjacent to the list of the purchase content displayed on the operation window, and the play means installed in the browser by the server is a streaming method by the operation of the play mode. Characterized in that to play the purchased content.

In the purchase content use step, the activation of the purchase content through the operation window arranges the download mode adjacent to the list of the purchase content displayed on the operation window, and transmits to the designated space of the computer to which the browser belongs by the operation of the download mode. It is characterized by.

Here, in the step of using the content, the transmission of the DRM that is required by the player from the content database to the player includes setting the content of the content database to include a representative DRM, and including the operation window in the browser. As a control means, a system interface for recognizing a player and a DRM conversion unit are activated to recognize a player connected to the browser. When the DRM required by the recognized player and the DRM set in the content database are different, the browser is read from the content database. The content is transmitted to a storage space of a computer to which the computer belongs, and the DRM conversion unit encrypts the DRM of the content database, and then encrypts the DRM according to the player to transmit the content to the player.

In this case, when the content includes the text, the text may be further converted and transmitted according to the text display requirement of the player.

On the other hand, the content transfer from the browser recognition of the browser to the player is to install a plug-in in the browser to activate the operation window and to transmit the DRM recognition requested by the player and the update information for DRM conversion to the player to be installed and installed in the browser. It features.

Next, a paid content management system is provided as a server / client system for implementing this according to the network-based paid content management method, and a server including a database and a control element (program) according to the schema according to the paid content management method. Is built.

In general, such a system is implemented as a control window that includes a control element and is operated by a user through a browser, and a database is constructed for this purpose, for example, a detailed formation of fields and records or a content transmission method including a related protocol or DRM, Alternatively, since image realization and the like are realized by a person of ordinary skill in the art, detailed descriptions thereof will be omitted.

On the other hand, in the present invention, the operation means including the actuation of the operation window as the input / output means and the control means through mouse click with the GUI (Graphic User Interface) component included therein and the driving overall accordingly is referred to as "mode".

As a network-based paid content management system, the present invention provides a purchased content database 14 in which content purchased by a user who is a user is a relational database with the member database 12 in a content database 10 in which paid content is premised on subscription. Wow:

And a list display unit 18 for displaying the purchased content as an operation means for invoking the purchased content by a logged-in user connected to the network according to the purchased content database 14, and the purchased content of the list display unit 18. The playback mode 26 for activating the streaming means of playing to use the contents adjacent to the list, the download mode 28 for performing the storage to the computer to which the browser 20 belongs, and the browser 20 separately from them. The operation window 16 is an interface in which a player transfer mode 24 is formed to transmit the purchased contents from the purchased contents database 14 to the portable player 22 connected thereto via a medium.

A system for recognizing the DRM of the player 22 connected to the browser 20 and the storage space state of the player 22 by the control means triggered by the player transfer mode 24 included in the operation window 16. In accordance with the interface unit 30 and the DRM requested by the player 22 recognized by the system interface unit 30, the selected content in the content database 10 is DRM-converted and processed through the system interface unit 30. The network-based paid content management system including a DRM conversion unit 32 for transmitting to the player 22.

In this case, the DRM conversion unit 32 is a temporary storage unit 34 and the temporary storage unit 34 and the temporary storage unit 34 is stored in the temporary storage of the content is transferred to the storage space of the browser 20 from the content database 10; A decryption unit 36 for decrypting the transmitted DRM and an encryption transmission unit 38 for encrypting the decrypted content to the DRM requested by the player and transmitting the encrypted DRM through the system interface unit 30. do.

In addition, between the DRM conversion unit 32 and the system interface unit 30 recognizes the updated DRM format requested by the player 22 and performs decryption / encryption according to the updated DRM format. It is characterized in that the DRM management unit 40 which is transmitted from the 48 and installed as a plug-in is further included and mediated.

In addition, the DRM conversion unit 32 further includes a text combination unit 42 for converting the text according to the text display requirement of the player 22 when the content includes the text, and including the same in the content for transmission. It features.

On the other hand, the operation window 16 is formed with a player display unit 46 for displaying the connection state and recognition state of the player 22 and the recognized player storage space by the system interface unit 30, the player The player transfer mode 24 is disposed on the player display unit 46 such that the player transfer mode 24 is activated when the player 22 is recognized by the display unit 46.

As described above, the present invention provides a method for managing paid content based on a network and a system thereof, in which a user can easily use paid content in accordance with various systems for driving contents within a legitimate scope.

To this end, the present invention manages paid content as a server / client system, and as the user and the content purchased by the user are related, the purchase content database 14 is converted into a relational database from the member database 12 and the content database 10. The paid content is managed, and the user uses the paid content in the legitimate scope of use defined by the DRM as a database is established in the system for the paid content once purchased.

Accordingly, since the purchase content database 14 is first formed as the relational database, login is premised to use the system of the present invention.

That is, if a user is not specified for any purchased content, the formation of the relational database is difficult, and if such a relational database is not formed, the purchased content is only a one-time download service, and thus it is posted. Likewise, it becomes cumbersome to manage DRM for playing content in a plurality of playback means such as a browser, a portable player, or a mobile having a portable player function.

Therefore, it is premise that the relationship database between the user and the purchased content is formed. For this purpose, the premise is to log in before the purchase of any specific content. If the user is not registered, the purchase of the content is performed after the login. Be sure to

The purchase of the content is performed through a payment system in a general electronic commerce system, and at the same time as the purchase of the content is completed, the content is stored in the purchased content database 14 as a relational database.

In addition, as the purchase content database 14 is formed, the operation window 16 is activated as an interface that enables the user browser 20 to access the purchase content database 14, and the operation window 16 is activated. The user will use the purchased content.

The use of the content is largely classified into three types, one of which is a reproduction of a streaming format in a server / client system, and a reproduction means (not shown) is activated by an application program provided by a server.

The other is the download of DRM content that runs on the Windows operating system, which allows it to be used within legitimate ways, for example, to post purchased content to a blog in streaming format, and to deliver the content that you have purchased to your PC. Own storage.

The other is the transmission to the portable player 22 held by the user, and the content is transmitted in accordance with the DRM format required by the different portable players 22.

The operation window 16 for this includes a list display unit 18 in which a list of purchased contents is listed and displayed, and each list of the list display unit 18 is adjacent to the play mode to play the streaming means. And a download mode 28 for performing PC download, and a player transfer mode 24 for performing transfer to the portable player 22 is arranged as an operation means.

In particular, the player transmission mode 24 is provided so that a separate player display unit 46 is provided, and the content is transmitted in a state where the connection state and recognition state of the player 22 are confirmed by the system interface unit 30. do.

This is because the content cannot be transmitted when the system interface unit 30 does not recognize the player or when the player does not recognize the DRM format. Therefore, the player 22 recognizes and recognizes the player 22 when the player interface 46 is activated. This is to prevent the error or inconvenience of the user in advance by interworking the player transmission mode 24.

The player display unit 46 is displayed by the activation of the system interface, and the system interface unit 30 is activated at the same time as the operation window is driven.

In this case, when the player 22 is not connected to the browser 20, the player's recognition state is notified to the user through the player display unit 46, and the player 22 is connected to the browser 20. In this case, the connection of the player 22 and its internal storage state are notified.

At this time, the internal storage state of the player 22 is notified in the form of an explorer, and such an explorer is provided in an ActiveX form embedded in a web page, for example, and activated.

On the other hand, the system interface unit 30 is linked to the actuation of the operation window 16 and the DRM management unit 40, the operation window 16 is activated and at the same time the DRM management unit 40 is updated in communication with the server 48 The DRM information is installed in the browser 20 of the corresponding user, and the updated DRM information is the DRM information of the newly added or newly added player of the DRM format, and is extended with a plug-in.

As a result, in the present invention, as the purchased content is transmitted in accordance with the DRM format required by the different portable players 22, a control means triggered by the player transmission mode 24 is formed, which is applied to the browser 20. The content database 10 according to the system interface unit 30 that recognizes the connected DRM of the player 22 and the storage space state of the player, and the DRM requested by the player 22 recognized from the system interface unit 30. The DRM conversion unit 32 includes a DRM conversion process for transmitting the selected DRM-converted content to the player 22 through the system interface unit 30.

The content transmission to the player 22 by the DRM conversion unit 32 is mediated by the user browser 20, the browser 20 is responsible for the conversion transmission, which is a separate DRM for any one content The reason for having a content database as a plurality of contents to have is because of the construction of an unreasonable database for any one content from the distributor's point of view.

Therefore, the content database 10 is implemented as including a representative DRM, and since the format of the license in the DRM (player) is different for each player's DRM system, in order to transmit content to each other using a different DRM system. The DRM conversion process is required, and if the server 48 handles the DRM conversion process, the server 48 will follow a lot, so that the conversion to DRM for each player 22 can be handled by the client program. In other words, the server / client system minimizes the load of the server 48.

Accordingly, the DRM converter 32 transfers the contents from the DRM requested by the player to the storage space of the browser 20 in the contents database, and the DRM of the contents in the temporary storage 34. And a decryption unit 36 for decrypting the encrypted content, and an encryption transmission unit 38 for encrypting the decrypted content to the DRM requested by the player and transmitting the encrypted content through the system interface.

On the other hand, the user's browser 20 should be able to recognize a newly released player to which the new DRM has been applied, and it is also required to perform decrypt and encrypt to the new DRM.

In this request, the user's browser 20 is reactivated by the network connection with the server 48, and the player 22 requests between the DRM conversion unit 32 and the system interface unit 30 for this purpose. The DRM management unit 40 further includes a DRM management unit 40 that is recognized from the updated DRM format and is transmitted from the server and extended in a plug-in manner to perform decryption / encryption according to the updated DRM format.

In addition, the DRM conversion unit further includes a text combination unit 42 which converts the text according to the text display requirement of the player 22 from the system interface and includes the content in the content when the content includes the text. .

Therefore, in the present invention, the user does not need to recognize the player 22 possessed by the user, and this matter is performed by the operation window 16 and the control means, except that the operation window 16 includes the system. The interface unit 30 is provided with a player display unit 46 for displaying the connection state and recognition state of the player 22 and the recognized storage space of the player.

This is because when the player 22 is not connected to the browser 20 as described above, the content is not transmitted, and the content of the content depends on whether the operation window 16 recognizes the DRM of the player 22. The presence or absence of the transmission is determined, and the presence or absence of the content is also determined according to the storage space secured in the player 22, so as to notify the user of the connection state, the recognition state, and the storage space state of the player 22.

Therefore, in the content transmission to the player 22, the user recognizes the connection and recognition state of the player 22 through the player display unit 46, and then checks the storage space of the player to perform the content simply. Will be sent.

As described above, according to the present invention, as the purchase content database is established in the system for the paid content purchased by the user in relation to the user and the content purchased by the user, the paid content in the legitimate scope of use defined by DRM. Is used through the purchase content database, and in particular, when the portable player and the browser are connected, the content is transferred from the purchase content database to the portable player through an interface provided from the server / client system, and the interface is a DRM of the portable player connected to the browser. By converting and transmitting the content including the DRM required by the player according to this, it is convenient to manage the paid content of the content distributor (system company) and used for various playback means for driving the content within the legitimate scope. There is a fee that the effect of the content using the convenient.
