An object of the present invention for solving the problem is a database connected to a user computer from a database and a user computer for classifying and storing run time information of a multimedia file stored in a recording medium which is one of a CD and a DVD for each recording medium. Receives run time information of at least one multimedia file stored in a medium, compares the received run time information with run time information previously stored in the database, and stores a recording medium connected to the user computer. It is to provide a recording medium authentication processing system including a server for authentication processing.

In the recording medium authentication processing system according to the present invention, a recording medium connected to a user computer from a database and a user computer for classifying and storing run time information of a multimedia file stored in a recording medium which is one of a CD and a DVD for each recording medium. Receive run time information of one or more multimedia files stored therein, and compare the received run time information with the run time information previously stored in the database to authenticate the recording medium connected to the user computer. It characterized in that it comprises a server for processing.

In the recording medium authentication processing system according to the present invention, the server transmits the multimedia file stored in the recording medium to the user computer in response to the recording medium authentication processing result.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a diagram schematically illustrating a system for providing a multimedia file download service according to the present invention. The system according to the present invention comprises a file providing server 10, a DB (15) and a user computer (20).

The file providing server 10 is a server that transmits a multimedia file to the user computer 20 and downloads the multimedia file to the user computer 20. The file providing server 10 provides a predetermined website to which the user computer 20 can access. The file providing server 10 authenticates a recording medium such as a CD 30 inserted into a CD ROM drive of the user computer 20 as described below. The file providing server 10 includes multimedia files to be downloaded by the user, and transmits the multimedia files to the user computer 20 according to the authentication result.

The DB 15 is a database provided with authentication information for authenticating the CD 30. The file providing server 10 authenticates the CD 30 by referring to a database built in advance in the DB 15. The DB 15 may be attached to the file providing server 10, may be provided in the server of the producer of the multimedia file such as the record producer, the file providing server 10 may be provided in a form that can be viewed on the web.

Hereinafter, a process of providing a multimedia file download service according to the present invention performed by the above system will be described with reference to FIG. 2.

The user first purchases a recording medium containing a multimedia file offline. In this embodiment, a music file produced in the MP3 format is illustrated as a multimedia file, and the CD 30 is illustrated as a recording medium. However, in addition to this, the multimedia file may be various video files and the like, and the recording medium may be a DVD or the like.

The user who purchased the CD 30 containing the multimedia file inserts the CD 30 into the CD ROM drive of the user's computer 20, and the website provided by the file providing server 10 on the Internet by the user's computer 20. (S10) Then, the user selects a menu requesting a download from a menu in the website and requests the file providing server 10 to download the MP3 file. (S20) At this time, the user requests a download. The MP3 file is the same file as any one of several MP3 files contained in the CD 30 previously purchased by the user.

For such a download request, it is preferable to provide a separate icon in the file providing server 10 for a download request command by the user who purchased the CD 30. As a result, the user can select the transmission by the content purchase on the general website and the transmission according to the free download request for the person who purchased the CD 30 according to the present invention.

Meanwhile, the file providing server 10 receiving the download request transmits an application program to the user computer 20 to perform a subsequent process. (S30) The application program is installed in the user computer 20 and the CD 30 is installed. As a program for reading the predetermined identification information contained in the file providing server 10 and transmitting it, it is provided in the same manner as the Active X control. The transmitted application is automatically executed in the user computer 20 (S40), and thus identification information for the CD 30 is transmitted from the user computer 20 to the file providing server 10. (S50) ID information is unique information for identifying the CD 30 inserted into the recording medium drive (CD ROM drive) of the user computer 20, which will be described later.

On the other hand, in the present embodiment illustrates a state where the user first inserted the CD 30 in the CD ROM drive of the user computer 20, if the CD 30 is not inserted into the user computer 20 The application program transmitted in step S30 will check the absence of the CD to display a message requesting the user computer 20 to insert the CD into the drive.

The file providing server 10 that has received the identification information at step S50 compares the identification information with the authentication information that it holds in advance, and identifies whether the CD 30 contains the MP3 file requested by the user. If it is determined that the CD 30 inserted in the user computer 20 is a recording medium containing the MP3 file requested by the user, the file providing server 10 requests the download. The MP3 file is transferred to the user computer 20 and provided. (S70)

By this process, the user who previously purchased the CD 30 offline can download and provide the same file as the multimedia file included in the CD 30 purchased by the Internet. Therefore, since the user can be provided with the same file on the web for the files purchased at a reasonable price, the user can enjoy the music while storing the file conveniently in a portable MP3 player or the like. Accordingly, there is no fear of illegal distribution of content by converting and distributing the file in the CD 30 purchased by the user into a separate digital file, and the purchase of the CD 30 includes the purchase of digital content (multimedia file). The effect is to activate the offline CD (30) purchase, which contributes to the activation of the music market.

Hereinafter, the above-described identification information and authentication information will be described in more detail.

The identification information is the unique information of the CD 30 contained in the CD 30, and the authentication information is authenticated by performing the comparison process in step S60 by the file providing server 10 as described above with respect to the identification information. This information is provided in advance. Accordingly, the identification information can be implemented in various ways, and the authentication information is provided in such a manner that the file providing server 10 is provided in advance by the record producer and stores the identification information in advance.

Such identification information may be configured as an authentication file that is generated and stored in a separate file on the CD 30. In this case, for example, the authentication file includes one additional file in the CD 30 for storing several music files, but the additional file is configured to include authentication data for authentication. The authentication information is configured as the same data as the authentication data included in the file for authentication. Accordingly, the identification information and the authentication information to be compared in step S60 are completely identical. In the case of adding such an authentication file, it is possible to assign a unique authentication number to each CD, so that authentication of individual CDs is possible. On the other hand, this method has the disadvantage that the file providing server 10 has to provide the authentication information for all the CDs produced, so the amount of authentication information to be provided is huge and the authentication information must be updated immediately after the CD is produced for all CDs. There is a disadvantage in that the new file must be added to the CD 30 so that it cannot be applied to a CD that is already manufactured and distributed.

As another example, the identification information may be configured as a unique serial number assigned to the CD. All CDs currently produced are assigned a unique serial number by the author, and all CDs with the same title are assigned the same serial number. As such, when the serial number of the CD is used as the authentication number, since the CD having the same title has the same identification information, the enormous amount of data is reduced as all CDs must be managed individually. On the other hand, even if the CD of the same title is produced by another producer or additionally produced by the same producer because the serial number is different, this must be a separate update process.

As another example, the identification information may be configured to include data extracted from a plurality of sites in the CD. That is, the data extracted from the various parts in the CD 30 are combined and used as one authentication data, and this authentication data is provided in the DB 15 as authentication information. The identification information transmitted in step S50 also becomes data extracted in the same manner by the application program. According to this method, there is an advantage that it can be applied to existing CDs because it does not add a separate authentication file. However, there is a disadvantage that the process of obtaining authentication information combining data extracted from the parts of the book number for the CD 30 is not easy in the present situation. For some CDs, such data extracted from a plurality of sites is provided by a manufacturer and provided by a company using the same, but a large number of CDs do not provide such data. Therefore, there is a disadvantage that it is somewhat difficult to build a database for authentication information.

As another example, the identification information may be configured as information on the run time of the file recorded on the CD 30. FIG. 3 shows an example of a database that should be built as authentication information in the DB 15 in this case. One CD 30 includes several MP3 files (typically 6 to 10 MP3 files), and CD serial number, CD name (record name, etc.) to identify the CD 30. , The names of the songs included, and respective fields for the runtime of each song are provided in the database. At this time, the run time for each song is a time required for each MP3 file to be reproduced. In the case of a music file, each piece of music is provided as second data within a range of about 3 to 5 minutes for each song.

In this way, the runtime of all the songs contained in one CD 30 is stored for each song and provided as authentication information. In step S50, as the identification information, the runtimes of all the songs currently stored in the CD 30 inserted in the user computer 20 are transmitted to the file providing server 10, and the file providing server 10 transmits these runtimes to the DB ( Compared with the authentication information stored in 15), the CD 30 is authenticated when both match.

At this time, the authentication of the CD 30 may be performed by comparing the runtimes of any one of the songs, or by comparing the runtimes of the plurality of songs, respectively, or by comparing the runtimes of the entire songs, respectively. It may be. At this time, in determining whether the runtime transmitted as the identification information in step S50 with respect to the individual songs is consistent with the runtime included in the authentication information, it may be based on whether or not both runtimes are completely matched. It is preferable to comply with whether or not it is the same within an error range. Typically, a digitalizing error occurs in the process of converting music recorded in an analog state into digital data, and the range of this error is usually within 1 second for a typical music file. Therefore, considering that there is a slight error between the runtime provided as the authentication information and the runtime of the song recorded on the actual CD 30, for a song having a difference within a range within 2 seconds when comparing the identification information and the authentication information. It is determined that the same run time. According to this, even when there is a designation error, authentication may be made in consideration of this. In addition, according to this method, the certification may be somewhat inaccurate when comparing a single song, but in general, when comparing all six to ten songs contained in one CD, the problem of certification inaccuracy is almost insignificant. There will be no.

According to such a run-time comparison method, there is an advantage in that acquisition is easy because data on the run time is provided by a producer at the time of producing a record. In addition, there is no inconvenience in producing a separate file because it uses the runtime data provided by the producer at all times without using a separate authentication file for certification of the CD. Also, there is an advantage in that the present invention can be applied to provide an authentication and download service.

According to the present invention as described above, a user who previously purchased a CD offline can receive and provide the same file on the Internet as the multimedia file included in the CD he purchased. Therefore, the user can enjoy the music while conveniently storing the file in a portable MP3 player or the like, and there is no fear of illegal distribution of content such as converting the file in the CD purchased by the user into a separate digital file and distributing it. It also contributes to the activation of.

In the above, the preferred embodiment of the present invention has been illustrated and described, but the present invention is not limited to the specific embodiments described above, and the technical spirit of the present invention and the following by those skilled in the art to which the present invention pertains. Various modifications and variations will be possible within the scope of equivalents of the claims to be described therein, and such variations will fall within the protection scope of the present invention.
