Description

  The present invention relates to a data protection technique for information storage media used for rental, such as CDs (compact discs) and DVDs (digital versatile discs) that store content data related to copyrights such as music and movies.

In CD and DVD information storage media that store music and video content, the data does not deteriorate even when duplicated by ripping. For the purpose of copyright protection, copy control data is stored together. Digital duplication is controlled (for example, Patent Document 1). In recent rental shops, those that are rented with a new rental permission are controlled by this copy control data so that they cannot be digitally copied.
JP 2003-16726 A

  It is not acceptable from the viewpoint of copyright protection to allow unlimited copying in the current situation where data can be copied without deterioration, but for example, even if a music CD (CD-DA) is borrowed from a rental shop, digital copying is not possible at all. So, the charm of using a rental is too little.

  Therefore, the present invention proposes an information storage medium, a server, and a rental method using these, which can establish a new rental method considering the viewpoint of copyright protection.

  The rental information storage medium according to the present invention reproduces stored content when the content, copy control data for controlling copying of the content, and the information storage medium is inserted into a medium reader of a computer. Through a playback program for operating the computer as playback means, a display program for operating the computer as display means for displaying on the display device a user interface for inputting instructions for copying content to another information storage medium, and the user interface When a copy command is input, an access program for operating the computer as an access means for accessing the server for user authentication via the Internet, and when an authentication result is returned from the server via the Internet, the copy controller Thus suppressing the copy control by the data, the replication program for operating a computer as a replication means for replicating the content to another information storage medium, and characterized by storing the.

  The server according to the present invention is a server that can be connected to the user terminal used by the rental member and the information terminal of the rental shop via the Internet, and includes member number data from the user terminal connected via the Internet. When the authentication request is received, it is confirmed whether or not the member number is registered in the database. If the member number is registered, the authentication result is returned to the user terminal and compared with the member number. Authentication result data is stored, and the stored membership number and authentication result data can be viewed on an information terminal of a rental shop.

  The rental method according to the present invention is a rental method using the information storage medium of the present invention and the server of the present invention, wherein the information storage medium is lent to a rental member at a rental shop, and the information storage medium Is inserted into the medium reader of the user terminal used by the rental member, the computer of the user terminal operates as a reproducing means for reproducing the content stored in the information storage medium and stores the content in another information storage. It operates as a display means for displaying a user interface for inputting a command to be copied on a medium on a display device. When a copy command is input through the user interface, the computer transmits to the server for user authentication via the Internet. The server that operates as an access means to access and receives the access When receiving the authentication request including the member number data from the terminal, it is confirmed whether the member number is registered in the database. If the member number is registered, the authentication result is returned to the user terminal, The authentication result data is stored in comparison with the member number, and the stored member number and authentication result data can be viewed on the information terminal of the rental shop, and the authentication result is transmitted from the server via the Internet. When returned, the computer of the user terminal operates as a copy unit that suppresses copy control by copy control data and copies content to another information storage medium.

  According to the rental information storage medium of the present invention, from the viewpoint of copyright protection, digital copying can be controlled by copy control data, for example, no copying can be performed. On the other hand, when a rental member wishes to copy, a mechanism is permitted to copy the content after accessing the predetermined authentication server via the Internet connection and performing user authentication according to the stored program. Can be built. By adopting a method of permitting copying by Web authentication, it is possible to easily charge for copyrights for copying, which contributes to the construction of a rental system in consideration of copyright.

  In addition, according to the server of the present invention, the comparison data between the rental member's membership number and the content copy information can be viewed on the rental shop information terminal. Charges for the number of times of copying can be collected for rental members who return storage media. The fee can include the amount related to copyright, which contributes to the construction of a rental system that considers copyright.

  Further, according to the rental method of the present invention, if the rental member wishes to copy while controlling the copy by using the information storage medium of the present invention as a rental product, the copy fee including the copyright-related amount is charged. Copying content can be permitted after charging. Therefore, it is possible to realize a rental method that takes copyright into consideration, and contribute to the construction of a rental system that is commensurate with the current situation in which digital copying has become commonplace.

  FIG. 1 shows a schematic configuration of a system according to the rental method of the present invention. Overall, an information terminal installed in the rental shop RS, a personal computer (PC) 2 as a user terminal equipped with a drive for inserting a CD 1, and a server 3 for user authentication that established a website were connected via the Internet. It has a configuration. Note that the PC 2 is not limited to a user-owned one, and may be any terminal that can be used by the user such as a kiosk terminal.

  In the rental shop RS, the CD 1 is rented out as an information storage medium in this example. This CD 1 is a music CD that has been subjected to digital rights management (DRM), stores music of a predetermined artist as content, and stores copy control data for controlling duplication. The copy control data is data such as the above-mentioned Patent Document 1, Japanese Patent Publication No. 2003-5000789, and Japanese Patent Publication No. 2003-523595, and can be heard without difficulty in a playback device such as a mini component or a portable player. Even if you try to make a digital copy with the built-in CD drive, it is impossible. Therefore, although reproduction and recording from CD1 to MD (minidisc) and from CD1 to tape using minicomponents and the like are allowed, copying by ripping using PC is not allowed. Also, CD identification information that can specify the type of CD, such as ISRC (International Standard Recording Code) and disc ID, is recorded on the CD 1 of this example.

  A rental member who borrows such a CD1 from the rental shop RS inserts the CD1 into a CD drive, which is a medium reading device of the PC2, and thereby plays the PC2 as a playback means for playing back the content stored in the CD1. Can be operated. For this reason, the CD 1 is of a multi-session type as shown in FIG. 2, stores contents in the audio session 1o on the inner circumference side, and stores various programs in the data session 1d on the outer circumference side. In the innermost lead-in area, a TOC area (not shown) is provided for disk management.

  When CD1 is inserted into the CD drive of PC2, the automatic playback function works, the playback program stored in data session 1d is read by the CPU of PC2, and PC2 operates as playback means. For example, the PC 2 operating as the reproducing means displays a user interface UI as shown in FIG. 2 on the display device. In the user interface UI of this example, a music cover image UI1 (for example, an artist image) is displayed in the center portion, and a music title UI2 is displayed in the lower left corner of the cover image UI1. When the cursor is placed on the title UI2 and clicked, the corresponding music is read from the audio session 1o and reproduced.

  In addition, an end button UI3 is displayed in the upper right corner of the user interface UI, and when the cursor is placed on the end button UI3 and clicked, an end command of the playback means is input. When the end of the playback means is instructed, the PC 2 discharges CD1 from the CD drive together with the end of the playback means according to the discharge program stored in the data session 1d of CD1. In other words, when the CD 1 is inserted into the CD drive, the playback means is automatically activated by the PC 2 and is ejected from the CD drive when the playback means is completed, which helps copy control.

  In the case of this example, the user interface UI displayed on the display device by the PC 2 operating as the playback means includes a CD creation button UI4 for executing content duplication. This CD creation button UI4 is a user interface for inputting a command to copy the content stored in CD1 to another CD (secure CD), and is displayed on PC2 in accordance with the display program stored in data session 1d of CD1. Is done.

  When the cursor is placed on the CD creation button UI4 and clicked, a copy command is input, and the PC 2 operates as an access means according to the access program including the URL stored in the data session 1d of the CD1, and the authentication server 3 connected to the Internet. To access. In the PC 2 operating as an access means, a browser is launched and a Web site established on the server 3 is displayed.

  As a result, the site screen B shown in FIG. 3 is displayed in the browser on the display device of the PC 2. On this screen, move the cursor to the member number input field B1 and input the member number from the keyboard or the like. Then, move the cursor to the CD creation button B2 for which the content stored in the CD1 is desired and click it. Along with the data for identifying the own device, the identification data of CD1 including the CD identification information such as the ISRC (for example, recorded in the TOC), the member number data, and the authentication request are transmitted to the server 3. When canceling replication, a cancel button B3 at the bottom of the screen can be clicked.

  In response to this, if the member number is registered in the database, the server 3 returns an authentication result to the PC 2 to permit copying. At the time of this authentication processing, the server 3 stores the data of the authentication result in comparison with the member number, and can view the stored member number and the data of the authentication result on the information terminal for the store clerk installed in the rental shop RS. Like that.

  The flow after renting the CD 1 as described above and inserting it into the CD drive of the PC 2 is shown in the flowcharts of FIGS.

  When the CD 1 is inserted into the CD drive of the PC 2 (S1), the playback program is automatically activated on the PC 2 to start the playback means (S2), and the user interface UI shown in FIG. (S3). Then, it is determined whether a copy command is input through the CD creation button UI4 in the user interface UI (S4). While there is no click on the CD creation button UI4 and no copy command is input, it is determined whether there is a click on the title UI2 of the music stored in the CD1 (S5), and if there is a click, the corresponding music is played. (S6) Further, click on the title UI2 is further determined. If the title UI2 is not clicked, it is determined whether or not the end button UI3 is clicked (S7), and the process returns to the click on the CD creation button UI4 (S4) unless the end button UI3 is clicked, that is, the playback means end command is input. . When the end button UI3 is clicked, CD1 is ejected from the CD drive (S8), and the playback means is terminated.

  If the CD creation button UI4 is clicked in step S4, the server 3 is accessed via the Internet, and the PC 2 displays the site screen B of FIG. 3 in the browser (S9). When the CD creation button B2 is clicked, the data including the input data in the member number input field B1 is transmitted to the server 3 to request authentication. When the server 3 receives the authentication request from the PC 2, the server 3 checks whether or not the membership number is registered in the database of the server 3, and only returns an authentication result permitting copying to the PC 2 if it is registered ( S10).

  By this authentication processing, the server 3 stores in a predetermined table that the content copy of the CD 1 has been performed once in comparison with the member number, and stores the number of copies and the member number data at the information terminal of the rental shop RS. Make it available for viewing. The number of times of copying is incremented every time there is an authentication request from the PC 2. The number of copies to be stored may be simply the number of times, but the date, time when the authentication request is made, and the CD number based on the CD identification information of CD 1 may be added information.

  When the authentication result is returned from the server 3, the PC 2 operates as a copying unit that copies the content stored in the CD 1 to another CD-R (for example, a DRM-secure CD) according to the copying program (S11). The PC 2 operating as a duplication unit notifies the CD-R to be written on the screen so as to be inserted into the CD drive, and starts duplication when the corresponding CD-R is inserted into the CD drive.

  The PC 2 that starts duplication temporarily suppresses duplication control by the copy control data of the CD 1, copies the content from the CD 1 to its own hard disk, and then copies this to another CD-R inserted into the CD drive. Execute the process to write to. The copy control data as described above is added to the copy to be written on the CD-R, and the copy control data is stored in the CD-R together with the copy content so that the re-copy is controlled. This re-copying control can be, for example, a control that prohibits re-copying to another CD, but enables transfer to a DRM compatible portable player or the like.

  With the above processing flow, the rental member can copy the content stored on the borrowed CD 1 to another CD-R / RW or the like after user authentication. The duplication fee is collected when the CD1 is returned to the rental shop RS. That is, according to the comparison data stored in the server 3, the payment terminal shown in FIG. 6 is displayed on the information terminal of the rental shop RS, and accordingly, the copying fee for the number of times of copying is collected at the time of return. Can do.

  In the illustrated settlement screen, the rental member's membership number and the copy number details authenticated by the server 3 are displayed as the CD number and date according to the CD identification information unique to each rental CD 1, and further at the rental shop RS. A check column for whether or not payment has been added is displayed. Such a settlement screen may be a method of storing and displaying the data sent from the server 3 at the information terminal, or a method of reading and displaying the data of the server 3 by the browser function of the information terminal.

  As in this embodiment, if management based on the above-described CD identification information unique to the CD 1 is incorporated in the server 3 for authentication, a different replication fee is set depending on the type of CD. Management such as setting a duplication permission period becomes possible. Alternatively, depending on the type of CD, direct copying from the CD to the CD-R is not permitted, and management such as permitting writing to the CD-R by performing DRM-controlled download from the server after authentication is also possible. It is. In addition, when collecting the additional fee for copying, there is an advantage that the actually borrowed CD and the CD number in the server record can be inquired and confirmed.

  As mentioned above, although one Embodiment of this invention was described, it is not restricted to said example. For example, CDs and CD-R / RWs are taken as examples of information storage media, but DVDs can also be applied. A CD drive can be applied to a DVD drive or the like, and a user terminal PC can also be applied to a DVD / HDD recorder or the like.
