Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the method for exchanging, renting and reselling the use rights of the multimedia file according to the present invention. In the following description, the same or corresponding members will be denoted by the same reference numerals and detailed description thereof will be omitted.

1 is a system connection diagram of a method for exchanging, renting, and reselling a use right of a multimedia file according to the present invention. As shown in the present invention, the present invention is connected to an Internet communication network by an Internet access means such as ADSL or VDSL, or various home uses. Or it is an information providing system consisting of a web server that is connected to the ubiquitous communication network by the office device to provide information to the service user.

In FIG. 1, the present invention provides a web server 201 for distributing an application program to each user and allowing access through a predetermined subscription and authentication procedure, but having a security system through a firewall to manage user information and other servers. A firewall 205 connected to a front end of the web server to block access of a third party to protect the user information and album information from the outside and maintain security; and a digital media of each user connected to the web server at all times. A first online server 202 for separately storing files into individual albums, a second online server 203 connected to the web server at all times to store and manage file information from a multimedia medium of the user, and the web server A third online server 204 that is constantly connected to and stores and manages encryption keys generated at the time of exchanging and downloading files. Users 206 are connected to the service operator's web server through the Internet communication network, ubiquitous communication network to configure and manage digital media albums, and to share and resell digital media files by exchange. .

2 is a flow chart illustrating a method of exchanging, renting and reselling a use right of a multimedia file according to the present invention, in which a user connects to an operator's web server and shows a digital media file, such as mp3 or a first step (310) of confirming whether to convert to a file such as wma, a second step (320) of reading file information from the medium and checking whether or not there is overlap with a digital media album already registered in the online server; A third step (330) of converting the digital media file from the medium and uploading it to an online server; a fourth step (340) of selecting and playing the file from the digital media album of the user; And exchange, rent and re-use the right to use the file by selecting the person who wishes to share or resell the file by exchanging the file. It is configured to include the selected files in a fifth step 350 and their digital media album sheet and the sixth step of downloading the file to select the device to download the file (360).

The first step 310 is a step of confirming whether the user connects to the operator's web server and converts his or her own media, such as an audio CD, into a digital media file, for example, a file such as mp3 or wma. If it is determined to convert (311) to perform the conversion, the next step is performed. Otherwise, the method moves to the fourth step 340, which is the reproduction step of the file.

The second step 320 is a step of reading media information, for example CDDB information, from the media and checking whether the media media overlap with the digital media album. The user recognizes his or her multimedia media as a personal computer or the media. Inserting the information into the device (321), reading the media information from the medium (322), and whether there is a duplicate file in his album stored in the operator's web server, In step 323, the same album exists.

In the embodiment of the present invention, the media uses an audio CD in which music files are recorded. However, the present invention is not limited thereto, and the medium information may include a title, an artist, a playback time, and a file title. Size and the like. If there is no duplicate file in the album in step 323, the next step is performed. If there is a duplicate file, the process moves to the fourth step 340, which is a file reproducing step.

The third step 330 is a step of converting the digital media file from the medium and uploading it to the album. The media information read in the second step is first uploaded to a web server and then the music file is converted into a digital media file. 331 and uploads it to the online server again (332). At this time, the digital media album is automatically generated in the form of a blog or mini homepage through the CDDB inquiry of the second step, and thus the user can easily configure his album blog or mini homepage through his own media. It can be used to communicate with other users.

The fourth step 340 is a step of selecting and playing a file from a digital media album of the web server. The fourth step 340 confirms whether a file is to be played (341) and selects (342) a file to be played (343). .

The fifth step 350 is a step of selecting a file from his digital media album and selecting a partner to share or resell the file by exchanging the file, exchanging, renting, and reselling the use rights of the file. A step 351 of checking whether or not to exchange is performed, a step 352 of checking whether an exchange condition is satisfied, a step 353 of selecting a file to be exchanged, and a step 354 of selecting a partner to be exchanged.

If the user wants to exchange the file in step 351, the next step is performed. Otherwise, the process moves to the sixth step 360, which is a file download step, and if the exchange condition is satisfied in step 352, that is, the user himself / herself If the conditions of this need match the need of the opponent, the exchange is performed by selecting the file and the partner to be exchanged (355). Otherwise, if the owner owns what the partner needs, or vice versa, With the permission, a one-sided lease 356 of the file for lease is made.

The sixth step 360 is to download a file by selecting a file from the digital media album of the user and selecting a device to download the file. A selection 362 followed by a selection 363 of the device to download. If the file is not downloaded in step 361, the operation ends.

3 is a diagram illustrating each step of the method for exchanging, renting, and reselling a use right of a multimedia file according to the present invention. As shown, the present invention provides a method of reading and updating media information from a multimedia medium possessed by a user (410), extracting media information of the multimedia medium and uploading a file to an online server (420); Playing a file from the album or exchanging, renting, and reselling a use right of the file (430); downloading the file from the album (440); and a legal procedure for downloading the file. By the process (460) of obtaining information protection and use rights.

In step 410, the multimedia medium is inserted (411), media recognition and DB inquiry (412), whether to edit the DB (413) and automatically input (415) or manually input (414) It is configured to include a function to update its own DB (416). This is performed by the user according to the user menu by installing the application program after the user through the procedure, such as membership registration.

That is, when a user executes an application program and inserts a multimedia medium (audio CD in the embodiment of the present invention), the information of the CD is first read and connected to the CDDB server to inquire whether there is album information for the CD. At this time, if there is information, the information is automatically input in the process of extracting the media information described later, and the information cannot be arbitrarily modified by the user. If there is no information in the CDDB, the user enters the information directly. In this case, modification is possible even after uploading. This is to save the file information that can be recognized by the CDDB at the time of file upload on the server so that the information of the CDDB can be updated or the album information can be updated by the server operator or each user. It can facilitate securing of own CDDB through temporary storage of potential user input album information and continuous extraction of information from external CDDB company's database.

In step 420, file information is read from the multimedia medium and converted into a digital media file (421), and then the digital media file is uploaded to an online server using a temporary folder (422) or directly uploaded to an online server (423). It is configured to include a function.

That is, when the CDDB related processing is completed by the process 410, the actual process of extracting the digital media file from the CD occurs. In this case, two matters of stability and speed should be considered. After this extraction, ripping, the file and album information (including CDDB recognition information) are automatically uploaded to the online server using a temporary folder or directly to the online server without using the temporary folder. In order to protect the right to use the file according to the present invention, it is preferable to upload the file directly to the online server without using a temporary folder.

The process 430 may include a function of managing a file in the album of the user on the web server (431), playing the file (432), or exchanging, renting, and reselling the right to use the album or the file (433). .

As described above, when the CD is uploaded to the web server as a digital media file through steps 410 and 420, the user can use three functions: album and file management, file playback online, and album or file exchange. This may be extended to use the functions as various office and home devices that can access the ubiquitous network through connection with an office network or a home network according to a ubiquitous environment to be constructed later.

In order to exchange the album or the file in the process 430, the functions of collecting and managing the information of the digital media file, as well as the function of searching for a user similar to the user's taste or the album and file information of another user, are elements. In the method of exchanging files, the file permissions are transferred for a specified time.

That is, in order to allow the authority for a file connected to one ID to be set to another ID for a certain period of time, the present invention uses an automatic exchange method, a manual exchange method, and a sharing setting method as described later in FIG. 5. .

At the same time, the file play in step 430 is possible only in an album owned online, but even if the file is owned by another user, the file cannot be played. This is to achieve the object of the present invention that the exchange of files is a temporary transfer form of the license as described above, and the purpose of maintaining the order of the rights relationship by allowing only one person to use one file.

In step 440, the user accesses (441) his album, selects (442) a file to download, determines a location or device to download (443), and then preferentially receives condition information about the file from the web server. It is configured to include the ability to download (444).

The above download function is a file uploaded to the user's album on the web server, the file stored in his album or borrowed from another user, such as personal computer, MP3 player or MP3 mobile phone, etc. It is intended to be downloaded to the device of the company and made available for secondary use. The most important point is to protect the file from being copied or redistributed.

For such a download, the user first accesses his album online and selects a file to download, and then selects a device to be downloaded. In the case of a personal computer, the user only needs to specify a folder location. In case of downloading to MP3 mobile phone, etc., you can use UMS method to recognize and save the device connected to personal computer through USB cable as a removable disk or use COM port communication by dedicated program provided by the manufacturer of the device. The transmission method can be used. Of course, the above methods should be applied to digital rights management (DRM) technology described below in order to block the duplication or redistribution of files.

The process 460 includes a function of performing an encryption on a file (461), generating an encryption key, inputting a condition (462), and then sending the encryption key to an owner server, that is, a license server (463). do.

As described above, when the location to download the file is determined, the condition information about the file is first downloaded from the web server as described above. If the condition information is specified as its file, the file is downloaded without the DRM packaging process. If the information is recorded as a file rented from another user, it is downloaded through the DRM packaging process.

Here, the application of the DRM technology when downloading the file is to block the duplication or redistribution of the file through the right protection as described above. In the present invention, the DRM technology may be applied to an application program or the DRM packaging process. Can also be used to ensure that a commercial DRM solution is available.

In this case, before the process 460 of packaging the DRM, a process 450 for checking whether to borrow a file license is performed, and after the process 460, a process of transmitting the file or downloading the file 470 to a designated device is performed. Is performed. In other words, if the file is in an own album or is borrowed from another user, the file is downloaded to a designated device, and if the file is transferred to the other user's album after receiving a request from another user for a predetermined period of time.

In addition, when a user downloads a file from a web server to another device or rents a file between users for secondary use, the encryption period must be specified first in the process of encrypting the file and generating an encryption key. In addition, the generated encryption key should be stored and managed on the operator's web server. At this time, the storage and management deadline is automatically deleted when the usage period specified in the encryption key is expired so as not to put unnecessary load on the server.

4 is a diagram illustrating a method of exchanging a right to use a multimedia file according to the present invention. In the present invention, as a method of exchanging a right to use a file, an automatic exchange method and a manual method are used to transfer the right to use the file for a predetermined time. The exchange method, the shared setting method and the reservation exchange method were used.

First, as shown in FIG. 4, the user automatically creates a wish list as shown in FIG. 4 and automatically searches for a user who matches his list based on the file. If you have a comparison (502) whether you own the album, the file is automatically leased to the rental folder between the two (503) and stored in his album (504), or the list available for lease (505) after receiving the ID This is a method of selecting a file by 506 and storing it in its own album (504).

In contrast, the manual exchange method allows a user to search for a desired file (507), and then display the file if the owner of the file sets a lease condition (e.g., exchanges with the desired file). It is determined whether or not (508) and the exchange between the two by the process 503 to 506, and if there is no corresponding rental condition, the owner of the file via the online such as a short message or an e-mail online The lease request is made by using all possible means of communication. In this case, when the user searches for and listens to the album of another user, the user may play a limited form in the form of a pre-listening.

In addition, the sharing setting method is to set a share on a network in units of files or albums, and at the same time, the sharing time can be set at the same time and the use rights of the file can be transferred for a predetermined time. In this case, it is preferable that a series of processes are generally performed in a one-to-one dialogue 509 to discuss the lease conditions 510 and then exchanged by the processes 503 to 506.

Finally, in the reservation exchange method, each user requests a file to be exchanged to a web server operator (511), and the operator DBs (512) it based on a request list of a plurality of users so as to remind the user with the corresponding files. In step 503 to step 506, the file exchange can be performed. By further extending such a reservation exchange system, the digital media file can be sold online, which will be described later in FIG. 5 as another embodiment.

FIG. 5 is a flowchart illustrating a method for selling digital media files online according to another embodiment of the present invention. In another embodiment of the present invention, the web server operator becomes a distributor and receives a predetermined price from a consumer for a digital media file owned by the web server. This is a way of transferring rights.

That is, in FIG. 5, when the user completes authentication 601 according to a predetermined procedure, the seller permits access to his web server 602 and checks 603 whether there is a purchase request from the user. In this case, when there is a purchase request, the seller presents a list of digital media files that can be sold (604), and a user who makes a purchase request presents (605) a list that he / she wants to purchase.

When the sellable list and the list to be purchased are presented to each other, the user can pay the predetermined price, transfer ownership, and exchange the file owned by the user, i.e., exchange the right to use the file. To select (606). In this case, when the user selects a file exchange method, the process of confirming the intention of exchanging the right of use of the file is again performed (609), and finally, the transfer of the right of use of the file is made (610), and the user pays the price. If the user selects a method of purchasing a file, a file use right is sold 608 through a predetermined settlement 607 step. In the case where ownership of the file is sold or transfer of the use right of the file is performed by the two purchase methods as described above, the DRM packaging process as described above with reference to FIG. 3 is similarly performed.

Therefore, the sharing and resale method by exchanging multimedia files according to the present invention as described above can solve two problems of a service currently operated and provided by many companies. First, in the case of a business model provided by an online AOD service company such as Bugs Music, according to the present invention, while another user is listening to the music uploaded by the user, even if the user himself is allowed to temporarily use the music, This will solve the copyright issue. Secondly, in the case of a file download service provided by a company such as Pop Amp or Nepster, according to the present invention, the user can legally listen to and exchange music purchased from the company with another user. Likewise, it can be sold to other users.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions and changes may be made without departing from the technical spirit of the present invention. It is obvious to those who have it.

As described above, the present invention relates to a method and a system for exchanging or reselling digital media files, wherein each user accesses a web server of a service operator connected to the Internet or an extended communication network, and connects his digital media album. It has the effect of enabling the 1: 1 exchange of files, rental and resale by organizing, managing and renting or transferring rights with other users.
