Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copyrighted-material data exchange system and copyrighted-materials data exchange system that allow users to freely exchange copyrighted information such as music, images, or videos through a network or an optical disk medium. The present invention relates to a method and a copyrighted work data exchange program.

[0002]

2. Description of the Related Art In recent years, software such as Napster or Gnutella has been developed and has become popular. In such software, a file obtained by digitizing a copyrighted work such as music information is copied between users via a network. With these software, the music information owned by one user is copied to the hard disk of another user one after another through the network, and many users can enjoy the music. Further, the copying of data by these software is not performed from a specific downloading computer, but is performed between computers between users. Therefore, there is an effect that the utilization efficiency of the entire network is improved by avoiding the situation where the access concentrates on a specific computer or the network.

[0003]

[Problems to be Solved by the Invention] However, Napste
The r or Gnutella system has the problem of ignoring copyright. That is, if the users copy the copyright information to each other by such a system, the sales of CDs, music tapes, etc. will decrease, and the income that the copyright holder can earn will decrease. Along with this, if the copyright holder does not create new music or video data, the user will not be able to enjoy the new music, resulting in a disadvantage.

In order to solve such a problem, SDMI (Se
Cure Digital Music Initiative) and other organizations have been established to propose new technologies. That is, data such as music is encrypted, and key information for decrypting the encryption is given only to a person who paid a proper price. Such a system is preferable to the copyright holder, but it is annoying to the user. For example, a user who once used a free system such as Napster may prefer the free system and may not use the paid system. In addition, there is no way to stop the music information, which is obtained after paying the price, when it is later transferred using a system such as Napster. Also, if the key information can be obtained by illegal means,
After all, since it will be possible to listen to music for free, there is a possibility that an illegal copy means for obtaining key information will appear.

Therefore, in the present invention, the copyrighted material data exchange can be promoted without the occurrence of such illegal copy, and the free exchange of the copyrighted material data between users can be promoted while paying the legitimate reward to the copyright holder. It is intended to provide a system, a copyrighted material data exchange method, and a copyrighted material data exchange program.

That is, in response to a transfer request for music information, data transfer between the receiver-side user terminal A and the sender-side user terminal B of the music information is permitted.

The billing processing means 108 includes the server computer 16 and the deposit computer 14 shown in FIG. 2, and ends the transfer of the music information between the receiver side user terminal A and the sender side user terminal B. After that, a billing process is performed on the deposit account of the recipient user who has obtained this music information, and the reward is paid to the deposit account of the sender user. The user registration means 110 includes the server computer 16 and the user database 18 shown in FIG. 2, and when the user identification means 102 recognizes a new user who is not a registered user, an ID number, a password, etc. The user registration is performed by adding identification information for user identification and setting bank account information (account number, personal identification number, etc.) for billing and reward processing.

The copyrighted material information registration means 112 is a server computer 16 and a music database 17 shown in FIG.
User-owned copyright information stored in the copyright storage means (corresponding to the hard disks 11 and 13) of the user terminals A and B, for example, music information and music database 17. Compare copyrighted material information that has been paid, such as music information, and if the copyrighted material information you own without paying the copyright fee, such as music information, is found, charge the user. After
The copyright information, eg, music information, is stored in the music database 17
Register with. The user identification means 102, the search result notification means 104, the data transfer permission means 106, the charging processing means 108, the user registration means 110, and the copyrighted material information registration means 112 are connected to the communication network D through a communication interface 118.

The copyrighted material search / transfer request means 114 is shown in FIG.
Which includes the computer 10 or 12 shown in FIG. 2, generates a copyrighted material search request with the login of the user terminal A or B, and matches the user's request based on the search result notified to the search request. It is configured to issue a data transfer request to the user who owns the product information. The data transfer means 116 is configured to include the computer 10 or 12 shown in FIG. 2, and in response to the data transfer request, the receiver side terminal A and the sender side terminal B are accompanied by the data transfer permission of the data transfer permission means 106. Data of copyrighted material information, for example, music information is transferred between them.
The copyrighted material search / transfer request means 114 and the data transfer means 116 are connected to the communication network D through the communication interface 120.

Next, the processing operation for exchanging copyrighted material data in the system configured as described above in the embodiment of the present invention will be described with reference to FIG. FIG. 4 shows client software SFX operating at the user terminals A and B and server software S operating at the center.
7 is a flowchart showing a procedure of a data exchange process performed by Xs in cooperation with each other.

In step SP1 of FIG. 4, the user terminals A and B log in. For example, when the user terminal A logs in to the copyright management server C using the client software SFX, step S
In P1, the user identification means 102 determines whether the user terminal A is a registered user or a new user. If the user terminal A is a new user, the process proceeds to step SP2, and the user registration means 110 operates to perform user registration. That is,
In step SP2, a user number (or user ID) for identifying the user, a password,
Processing such as transfer of bank account information is performed for exchanging money.

When the user registration is completed, the processing proceeds to step SP3, and the copyright information registration means 112 operates to register the copyright information, such as music information, into the music database 17. That is, in this step SP3, the client software S
The FX scans the inside of the hard disk 11 owned by the user terminal A. In this scan, a list of music information for which the user terminal A has paid the copyright fee in the past is retrieved from the music database 17, and the hard disk 1
1 compared to the internal file. As a result, the list of the music files owned by the user terminal A by paying the copyright fee is confirmed, and the server software SX running on the server computer 16 is notified. Further, when the music information owned by the user terminal A is found at the time of scanning without paying the copyright fee, the billing processing means 108 operates and a new information is added to the user terminal A. Billing is done. In this way, the list information of the music files owned by the user terminal A is completed.

Further, in step SP4, the copyrighted material information registration means 112 operates so that the list information of the music files owned by the user terminal A is changed to the user terminal A.
Is registered in the music database 17 together with the ID information indicating Such processing is performed for all users who have logged in. As a result, the latest information of the music information stored in the hard disk of each user is stored in the music database 17 as a list.

Each music information is recorded in a format as shown in FIG. That is, the music information 22 is recorded as compressed data subsequent to the header information 21 indicating the name of the artist and the song name. Following this, the owner information 23 is recorded as the ID of the user who paid the copyright fee, and finally the parity 24 calculated throughout the entire data is recorded.
Has been added.

Next, the process proceeds to step SP5, and waits for a command request from each user. For example, assuming that the user terminal B has logged in to the copyright management server C and the user terminal B issues a search command, the search result notifying unit 104 operates and the processing is performed in step S.
In P6, the music database 17 is searched for a file corresponding to the requested keyword of the user terminal B. If the user terminal B inputs a song name, an artist name, or the like as a keyword, the user terminal B finds data matching the request of the user terminal B from among a lot of user information stored in the music database 17, and the search result is obtained. The list is notified to the user terminal B. After that, the process returns to step SP5 and enters the standby state.

Based on the notified search result list, the user terminal B specifies the ID and file name of the user who has the music data that matches his request, and notifies the copyright management server C. Along with this, when the data transfer permission unit 106 configured by the server software SX operates and accepts the transfer request of the music information designated by the user terminal B, the process proceeds to step SP7, and between the designated users. Allow data transfer.

For example, when the user terminal B requests a music file owned by the user terminal A, the data transfer means 116 composed of the user client software SFX of the user terminal A and the client software of the user terminal B. Data transfer means 1 composed of SFX
16 and communicates with the hard disk 1 of the user terminal A.
1 is transferred to the hard disk 13 of the user terminal B via the communication network D such as the Internet. By this transfer, the user terminal B can play and enjoy the music file owned by the user terminal A.

When such file transfer is completed, the processing shifts to step SP8, and the charging processing means 108 operates to perform the charging processing. That is, a predetermined amount of money (for example, 100 yen) is deducted from the deposit account of the user terminal B that newly obtained the file. For the deposit account of the user terminal A that provided the file, for example, 1
0 yen is paid as a bounty. Of the 100 yen obtained from the user terminal B, the remaining 90 yen after deducting 10 yen paid to the user terminal A is paid as the operating cost of the system and the copyright fee to the copyright holder. Such money balance processing is realized by the server computer 16 exchanging information with the deposit computer 14 regarding the data transfer result, and the deposit computer 14 updating the deposit data accumulated in the deposit database 15.

On the other hand, if the data transfer is canceled halfway due to some trouble, money is paid according to the size of the data actually transferred. For example, if the transfer is interrupted when exactly half of the music data is transferred, 50 yen will be deducted from the account of the user terminal B. In addition, the user terminal A is paid a reward of 5 yen. Also, the user terminal B can perform a new search after this. For example, if the user of another user terminal has the same data, the other half of the data can be transferred from the user of another user terminal. In this case, when the data transfer to the user of another user terminal is completed, the user terminal B pays an additional fee of 50 yen. Further, another user terminal can obtain a reward of 5 yen.

When the billing process is completed, the process proceeds to step S.
After shifting to P9, the owner information 23 is changed for the file transferred to the hard disk 13 of the user terminal B. That is, as shown in FIG.
The portion containing D is replaced with the ID of the user terminal B as shown in FIG. Further, the parity 24 is also recalculated and updated. After this, the processing is step SP5.
Return to and continue to wait for new instructions from new users.
Similarly, the user terminal B can obtain new music data.

Therefore, in the data exchange system according to the present embodiment, the music data obtained as described above is obtained by correctly paying the copyright fee.
The user terminal B can listen to this music proudly. In addition, the user terminal A that has provided the data can obtain a reward of 10 yen as a price for the infrastructure provided by itself. Further, the user terminal B that has acquired the music data in this manner can further transfer the music data in response to a transfer request from another user. By cooperating with the distribution of music data in this way, the user terminal B can also receive a reward. Therefore, if the user terminal B continues to provide the data and transfers the music data to, for example, 10 users,
It is also possible to recover the money (100 yen) originally paid as the copyright fee as a reward.

Therefore, according to the present embodiment as described above, by paying the bounty to the user who provided the data based on the correct method, the attractiveness of this copyrighted-material data exchange system is improved, and the existing Napster is changed. It is considered that users will migrate from such systems. Also, for the user, since this system has a great merit, it is expected that there will be less demand for destroying the system.

In the first place, the user who provided the file provides his / her own hard disk to the public, constantly connects the network to prepare the environment, and provides convenience to other users. That is, when applied to the conventional sales form, it corresponds to making the same efforts as a CD shop in which compact discs and the like are lined up in a store and the copyright holder and other users are in contact with each other. Therefore, it is natural that the bounty is paid to the user who provided the file. Also, due to the payment of the bounty in this way, this work data exchange system can be used by the sender of the existing Napst
It will be more attractive than a system like er.
As a result, users such as Napster will naturally migrate to this system and copyright protection will be realized. Moreover,
The copyright holder who creates music, images, video images, etc. is paid a valid copyright fee each time a new user appears. As a result, a large amount of copyright fees will be paid to authors who have created popular works, high quality music, images, video images, etc. will be created, improving the cultural level. You can

Further, in the copyrighted material data exchange system according to the present embodiment, in order to prevent falsified music data from being distributed, for example, when data transfer is performed in step SP7, parity information embedded in the data, etc. You can also check to make sure the data you are transferring is correct. At this time, the parity 24 can be used, or the tampering can be found by calculating and comparing data that extracts the characteristics of the music information 22. By thus configuring the system so as to prevent data tampering, it becomes possible to construct a system that is highly satisfactory for the user.

Next, another embodiment of the literary work data exchange system according to the present invention will be described with reference to FIG.
In FIG. 1, the case where the data transfer is performed through the Internet has been described, but in this case, when the data amount is large, it takes time and the efficiency may be low in some cases. Therefore, as shown in FIG. 5, a case where data is transferred using the optical disk medium 31 instead of the Internet will be described.
In FIG. 5, the music data for which the user terminal A has already paid the copyright fee is recorded on the optical disc medium 31. That is, as the owner information 23, the ID of the user terminal A
Are recorded in the music data recorded on the optical disc medium 31. The same reference numerals as those in FIG. 1 denote the same components as those in FIG.

In this way, the optical disk medium 31 which the user of the user terminal A originally owned is reproduced by the optical disk reproducing device 32 of the user terminal A, and the optical disk medium 3 is reproduced.
A case in which the music information stored inside 1 is transferred to the hard disk 13 owned by the user terminal B via the computer 12 will be described.

The user terminal B notifies the server software SX of a request to transfer the music data inside the optical disc medium 31 through the client software SFX. Upon receiving such a transfer request, the server software SX advances the process to step SP7 to transfer data between the designated optical disk medium 31 and hard disk 13. Since this transfer does not go through the Internet, it is completed in a short time.

When the file transfer is completed, the process proceeds to step SP8 and the billing process is performed. That is, the user terminal B that newly obtained the file pays a predetermined amount (for example, 100 yen) from its own account. Further, the owner information 23 recorded inside the file is read out,
Money of 10 yen is paid to the user terminal A as a reward. Of the 100 yen obtained from the user terminal B, the remaining 90 yen after deducting 10 yen paid to the user terminal A is paid as the operating cost of the system and the copyright fee to the copyright holder. Such money balance processing is realized by the server computer 16 exchanging information with the deposit computer 14 regarding the data transfer result, and the deposit computer 14 updating the deposit data accumulated in the deposit database 15.

When the billing process is completed, the process proceeds to step S.
After shifting to P9, the owner information 23 is changed for the file transferred to the hard disk 13 of the user terminal B. That is, as shown in FIG.
The portion containing D is replaced with the ID of the user terminal B as shown in FIG. Further, the parity 24 is also recalculated and updated. The post-processing returns to step SP5 and continues to wait for a new instruction from a new user.

By performing the processing as described above, it becomes possible to exchange data not only via a network but also through a medium such as an optical disk and protect the interest of the copyright holder. The user terminal B can also store the music information thus obtained in another medium and copy it to the user of another user terminal C.
At this time, if the user of the user terminal C pays the copyright fee, the user of the user terminal B can obtain a part of the copyright fee. Therefore, the user of the user terminal B also promotes copying in the correct method according to the present system. To do. In this way, the music data is copied one after another, but the profit of the copyright holder is secured at all stages.

In the above embodiment, the case where music information is exchanged between users has been described, but the present invention is not limited to this, and the same applies to images, videos and other copyrighted work information. Of course, it can be applied as follows.

[0050]

As described above, according to the literary work data exchange system, the literary work data exchange method, and the literary work data exchange program of the present invention, when the literary work information files are exchanged between users, the recipient Users pay money as copyright fees, so the rights of the copyright holders are protected,
It can contribute to the development of music and other copyright industries. Moreover, the sender user can obtain a part of the money paid by the receiver user as a reward, which makes the system attractive. Therefore, while paying the legitimate reward to the copyright holder without the unauthorized copying,
It is possible to promote free exchange of copyrighted work data between users.
