Description

  The present invention relates to a copyright management support system, method and program for supporting accurate management of copyright licenses.

  Today, various contents are provided through various media such as television and movies. Various copyrights are related to such content, and a license is required to use such content. In view of this, an information processing system that simplifies the copyright processing such as a license and mediates / supports the copyright processing of the content copyright has been studied (for example, see Patent Document 1). In the technique described in this document, when the data transmitting / receiving apparatus receives the content from the copyright holder of the content, the data transmitting / receiving device recognizes the transmission line number of the transmission terminal by the transmission line number recognition mechanism. Next, the transmission line number is embedded in the content as a digital watermark by the digital watermark embedding device, and the watermarked content is returned. In addition, when the data transmitting / receiving apparatus receives content that requires the copyright owner's use (purchase) permission, the digital watermark detection apparatus detects the transmission line number embedded in the digital watermark and requests information on the transmission line number. Reply to the original.

In addition, the distribution of digital contents has been activated, and various content management systems are being studied. For example, a content sales system capable of easily selling or purchasing one or a plurality of digital contents subjected to copyright protection according to the type of data has been studied (see, for example, Patent Document 2). The content sales system described in this document sets product information composed of one or a plurality of digital contents, sells the product as a product, a content management unit that records and distributes the digital content included in the product, Is provided. In addition, a license management unit is provided that permits use of the digital content by setting a license issuance condition for each digital content and distributing the license. Then, the digital content is reproduced on the information terminal while communicating with the product management means, the content management means, and the license management means.

  Next, processing when performing copyright management support according to the present embodiment will be described. Here, an overall procedure (FIG. 7), an implementation status confirmation process (FIG. 8), and a new sales confirmation process (FIGS. 9 to 11) will be described in this order.

  When a copyright license is purchased, purchase contract information is registered (step S1-1). Specifically, the content information record 220 and the purchase contract information record 230 are generated and registered in the content information storage unit 22 and the purchase contract information storage unit 23, respectively.

  On the other hand, for the copyright license purchased and sold, an implementation status registration process is performed (step S1-2). Specifically, as will be described later, in the purchase contract information record 230 and the sales contract information record 240, the execution history is additionally registered sequentially.

  When a new copyright license is sold, a new sale confirmation process is performed (step S1-3). Here, it is confirmed whether there is any problem in relation to a purchase contract or other sales contracts with respect to a license of a copyright desired to be newly sold.

  Next, when a copyright license is sold, sales contract information is registered (step S1-4). Specifically, the sales contract information record 240 and the holdback record 241 are generated and registered in the sales contract information storage unit 24.

Each process executed in the above procedure will be described in detail below.
(Confirmation process of implementation status)
First, the implementation status confirmation process will be described with reference to FIG.

  The control unit 21 of the copyright management support server 20 executes execution information acquisition processing (step S2-1). Specifically, the implementation status confirmation processing unit 210 of the control unit 21 acquires implementation information. For example, in the user terminal 10, the implementation information input by specifying the work ID, the episode ID, the right type ID, and the right type detail ID is acquired.

  In addition, for example, in the case of a broadcast program on a television or the like, it is also possible to periodically obtain implementation information using a program guide published on the Internet or the like. In this case, a media correspondence table in which a right type ID and a right type detail ID are registered in correspondence with the media disclosed in the program guide is used. Then, the implementation status confirmation processing unit 210 searches the program guide using the titles of works and episodes recorded in the content information storage unit 22 as keywords. When the content matching the keyword is detected in the program table, the implementation status confirmation processing unit 210 identifies the right type ID and right type detail ID based on the media correspondence table. Then, the implementation status confirmation processing unit 210 records the implementation history in the purchase contract information storage unit 23 and the sales contract information storage unit 24 with the broadcast date of the program as the implementation date.

  Next, the control unit 21 of the copyright management support server 20 executes a limit number confirmation process (step S2-2). Specifically, the implementation status confirmation processing unit 210 of the control unit 21 counts the number of implementations recorded in the implementation history of the sales contract information record 240. Then, the number of executions is compared with the number of sales contract information record 240 limit.

  When the number of executions reaches the number limit (in the case of “YES” in step S2-2), the control unit 21 of the copyright management support server 20 executes a right period expiration process (step S2-3). Specifically, the implementation status confirmation processing unit 210 of the control unit 21 acquires the current date from the system timer. Then, the implementation status confirmation processing unit 210 updates and records the current date as the end date of the right period of the sales contract information record 240. Thereby, this sales contract can be terminated and a new sales contract can be concluded.

  Next, the control unit 21 of the copyright management support server 20 executes a confirmation process for the presence / absence of holdback (step S2-4). Specifically, it is confirmed whether or not the holdback record 241 associated with the sales contract information record 240 is registered.

  When the holdback record 241 is registered (in the case of “YES” in step S2-4), the control unit 21 of the copyright management support server 20 executes a holdback end process (step S2-5). ). Specifically, the implementation status confirmation processing unit 210 of the control unit 21 updates and records the current date as the end date of the holdback period. Thereby, this holdback can be terminated.

  When the number of executions has not reached the number limit (in the case of “NO” in step S2-2), or when the holdback record 241 is not registered (in the case of “NO” in step S2-4). Then, the implementation status confirmation process is terminated.

(Contract status confirmation process for new sales)
Next, the contract status confirmation process at the time of new sales will be described with reference to FIGS.
When performing a new sale, first, the browser program of the user terminal 10 is activated and the copyright management support server 20 is accessed.

  In this case, the control unit 21 of the copyright management support server 20 executes user authentication processing (step S3-1). Specifically, the copyright management support server 20 transmits login screen data to the user terminal 10 via the network. The login screen is displayed on the display of the user terminal 10 that has received the login screen data. This login screen has input fields for employee code and login password.

  When the send button is selected after inputting the employee code and the login password in each entry field of the login screen, the user terminal 10 transmits a login request to the copyright management support server 20. The login request includes data regarding the entered employee code and login password.

  The user authentication unit 211 of the control unit 21 that has received the login request uses the employee master in the master data storage unit to check whether the employee code and login password included in the login request are registered. When the user authentication is successful, the user authentication unit 211 provides menu screen data corresponding to the authority of the employee to the user terminal 10. Here, it is assumed that menu screen data including a selection button for executing a sales proposal is provided to an employee who has sales rights for a copyright license. Specifically, the content search button displayed on the menu screen is selected. In this case, the user terminal 10 transmits a search screen request to the copyright management support server 20.

  The control unit 21 of the copyright management support server 20 that has received the search screen request executes search condition setting processing (step S3-2). Specifically, the control unit 21 of the copyright management support server 20 provides content search screen data to the user terminal 10. Then, the content search screen is displayed on the display of the user terminal 10 that has received the content search screen data. This content search screen includes a keyword input field for searching for content. The genre and title name can be entered in the keyword input field of the content search screen. When the transmission button is selected after inputting the keyword, the user terminal 10 transmits a search request to the copyright management support server 20. This search request includes data related to the input keyword.

The control unit 21 of the copyright management support server 20 that has received the search request executes content search processing (step S3-3). This content search process will be described with reference to FIG.
Here, the control unit 21 of the copyright management support server 20 executes a record search process using the received keyword (step S4-1). Specifically, the search processing means 212 of the control unit 21 uses the content information storage unit 22 to search for the content information record 220 including the received keyword. If the content information record 220 can be extracted, the search processing means 212 identifies the work ID and episode ID of the extracted content information record 220.

Next, the control unit 21 of the copyright management support server 20 executes a process for identifying content whose right period remains in the purchase contract record (step S4-2). Specifically, the search processing means 212 extracts a purchase contract information record 230 including the specified work ID and episode ID from the purchase contract information storage unit 23. Next, the search processing means 212 specifies the right period in the extracted purchase contract information record 230. Then, the search processing means 212 obtains the current date from the system timer, specifies the purchase contract information record 230 whose end date of the right period has not reached the current date, and temporarily stores it in the memory.

  Next, the control unit 21 of the copyright management support server 20 executes a collation process for the exclusive period of the sales contract (step S4-3). The search processing means 212 identifies the sales contract information record 240 including the work ID, episode ID, right type ID, and right type detail ID of the purchase contract information record 230 specified in step S4-2, and this sales contract information record. The end date of the exclusive period recorded in 240 is acquired. Then, the work ID, episode ID, right type ID, and right type detail ID for which the exclusive period is set until the end date of the right period of the purchase contract information record 230 are specified, and the purchase contract information record 230 related thereto is temporarily stored. Delete from allocated memory.

  Next, the control unit 21 of the copyright management support server 20 executes a holdback period verification process (step S4-4). Specifically, the search processing means 212 specifies the holdback record 241 including the work ID, episode ID, right type ID, right type detail ID of the purchase contract information record 230 specified in step S4-2, Get the end date of the back period. Then, the work ID, episode ID, right type ID, right type detail ID set for the holdback period until the end date of the right period of the purchase contract information record 230 is specified, and the purchase contract information record 230 related thereto is temporarily stored. Delete from stored memory.

  And the control part 21 of the copyright management support server 20 performs the specific process of the content with the right period of a purchase contract remaining (step S4-5). Specifically, the search processing means 212 specifies the work ID and episode ID of the purchase contract information record 230 remaining in the memory. With respect to such a purchase contract information record 230, the purchased right remains. Thus, the content search process ends.

Then, the process returns to the contract status confirmation process shown in FIG.
Here, the control unit 21 of the copyright management support server 20 executes an output process of the available list (step S3-4). Specifically, the available list creation unit 213 of the control unit 21 extracts the content information record 220 including the identified work ID and episode ID, and creates the available list 300 (FIG. 12) in which the content is displayed as a list. . This available list 300 includes information on the title, episode title, and genre of the content information record 220 for each extracted content. Further, this available list 300 is associated with selectable icons for selecting each content.

  In this case, a display screen 500 including the available list 300 is output to the display of the user terminal 10 as shown in FIG. The selectable icon output to the display screen 500 stores the work ID and the episode ID in association with each other. When each icon is selected, a detailed request including data relating to the work ID and the episode ID associated with the selectable icon is transmitted to the copyright management support server 20.

  The control unit 21 of the copyright management support server 20 that has received the detailed request executes a copyright expansion list output process (step S3-5). Here, when content is selected in the available list 300 output on the display of the user terminal 10, the user terminal 10 transmits a detailed request including data relating to the work ID and the episode ID to the copyright management support server 20. To do.

The control unit 21 of the copyright management support server 20 that has received the detailed request acquires a purchase contract information record 230 and a sales contract information record 240 by using the received work ID and episode ID. A copyright expansion list 310 (time on the first axis (here, horizontal axis) and content, right type ID, right type description ID, target country, and language on the second axis (here, vertical axis) FIG. 12) is created. In the copyright development list 310, the right period and holdback period of each right are displayed using the acquired purchase contract information record 230 and sales contract information record 240. Then, the control unit 21 of the copyright management support server 20 transmits detailed screen data including the copyright development list to the user terminal 10. This detailed display screen data is provided with an input field 312 in which it is possible to set the right period for which sales are desired and the presence or absence of monopoly.

  The detailed display screen 510 shown in FIG. 12 is displayed on the display of the user terminal 10 that has received this data. By using this detailed display screen 510, it is possible to set a selection button for each right, a right period, and whether or not there is a monopoly.

  If there is a copyright for which license sales are desired, this copyright is selected in the copyright expansion list, and if necessary, using the input field 312, a right period (sales desired right period) for which sales are desired, Choose whether or not you wish to monopolize. When the transmission button on the detail display screen 510 is selected, the user terminal 10 transmits a confirmation request to the copyright management support server 20. This confirmation request includes the selected work ID, episode ID, right type ID, right type detail ID, target country, language, and data regarding the desired sales right period (sales desired target range data). Further, when the exclusive request is selected, the user terminal 10 includes data related to the exclusive flag in the confirmation request.

The control unit 21 of the copyright management support server 20 that has received the confirmation request executes confirmation processing (step S3-6). This confirmation process will be described with reference to FIG.
Here, the control unit 21 of the copyright management support server 20 acquires the right range desired for sale (the desired range for sale) (step S5-1). Specifically, the contract status acquisition processing unit 215 of the control unit 21 selects, from the user terminal 10, the selected work ID, episode ID, right type ID, right type detail ID, target country, language, and input sales. Obtain desired sales target range data including data on the desired rights period.

  And the control part 21 of the copyright management assistance server 20 performs the collation process with a purchase contract (step S5-2). Specifically, the contract status acquisition processing unit 215 of the control unit 21 uses the purchase contract information storage unit 23 to determine the work ID, episode ID, right type ID, right type detail ID, target country, and language included in the confirmation request. Use to retrieve the purchase contract information record 230.

  And the control part 21 of the copyright management assistance server 20 performs the confirmation process of the presence or absence of the shortage in a purchase contract (step S5-3). Specifically, the status confirmation processing unit 216 of the control unit 21 compares the right period of the purchase contract information record 230 acquired from the contract status acquisition processing unit 215 with the desired sales right period included in the confirmation request.

  For example, as shown in FIG. 13, when the purchased right period is period T1 and the desired sales right period included in the confirmation request is set as period T2, the right in period T11 is insufficient. As described above, when the right period of the purchase contract information record 230 is shorter than the desired sales right period included in the confirmation request (in the case of “YES” in step S5-3), the status confirmation processing unit 216 determines the shortage range. The output process is executed (step S5-4). In this case, the status confirmation processing unit 216 notifies the user terminal 10 that there is a shortage range, and an alarm that displays the shortage range is output on the display of the user terminal 10.

Next, the control unit 21 of the copyright management support server 20 executes collation processing for the same rights that have already been sold (step S5-5). Specifically, the contract status acquisition processing unit 215 of the control unit 21 uses the sales contract information storage unit 24 to set the work ID, episode ID, right type ID, right type detailed ID, target country, and language included in the confirmation request. Use to retrieve the sales contract information record 240.

  And the control part 21 of the copyright management assistance server 20 performs the confirmation process of the presence or absence of duplication in a sales contract (step S5-6). Specifically, the status confirmation processing unit 216 of the control unit 21 compares the right period of the sales contract information record 240 acquired from the contract status acquisition processing unit 215 with the desired sales right period included in the confirmation request. Here, when the exclusive period is set for the right of sale, the exclusive period is set for the right to sell, or the exclusive period is set for both, Check for duplication. Further, even when the holdback record 241 is set for the already sold right, it is confirmed whether there is an overlap with the desired sales right period.

  For example, as shown in FIG. 13, when the same right with the exclusive period of the period T3 is already sold, it overlaps with the desired sales right period in the period T12. Thus, when there is an overlap in the right period of the sales contract information record 240 and the holdback period of the holdback record 241 with respect to the right period included in the confirmation request (in the case of “YES” in step S5-6). The status confirmation processing unit 216 executes the overlapping range output process (step S5-7). In this case, the status confirmation processing unit 216 notifies the user terminal 10 that there is an overlapping range, and an alarm indicating the overlapping range is output on the display of the user terminal 10.

  Next, the control unit 21 of the copyright management support server 20 executes a collation process for related rights that have already been sold (step S5-8). Specifically, the contract status acquisition processing unit 215 of the control unit 21 uses the related right information storage unit 25 to relate the right type ID, the right type detail ID, the target country, and the language included in the confirmation request. A record 250 is extracted. Then, the contract status acquisition processing unit 215 specifies other right type ID, right type detail ID, target country, and language recorded in the related right information record 250. Next, the contract status acquisition processing means 215 uses the identified right type ID, right type detail ID, target country, language, and work ID and episode ID included in the confirmation request in the sales contract information storage unit 24. The sales contract information record 240 is searched.

  And the control part 21 of the copyright management assistance server 20 performs the confirmation process of the presence or absence of duplication in a sales contract (step S5-9). Specifically, the status confirmation processing unit 216 of the control unit 21 compares the right period of the sales contract information record 240 acquired from the contract status acquisition processing unit 215 with the right period included in the confirmation request. In this case as well, if the exclusive period is set for the right of sale, the exclusive period is set for the right to sell, or if the exclusive period is set for both Check for overlap with the monopoly period. Further, even when the holdback record 241 is set for the already sold right, it is confirmed whether there is an overlap with the desired sales right period.

  For example, as shown in FIG. 13, in the case where the related right for which the exclusive period of period T4 is set is already sold, it overlaps with the desired sales right period in period T13. As described above, when there is an overlap in the right period of the sales contract information record 240 and the holdback period of the holdback record 241 with respect to the desired sales right period included in the confirmation request (in the case of “YES” in step S5-9). In step S5-10, the status confirmation processing unit 216 executes the overlapping range output process. In this case, the status confirmation processing unit 216 notifies the user terminal 10 that there is an overlapping range, and an alarm indicating the overlapping range is output on the display of the user terminal 10.

  On the other hand, if there is no shortage in the purchase contract (in the case of “NO” in step S5-3), or if there is no overlap in the same rights that have already been sold (in the case of “NO” in step S5-6), the relationship between the existing sales If there is no duplication of rights (“NO” in step S5-9), no alarm is output in each verification process. Then, the control unit 21 of the copyright management support server 20 ends the confirmation process shown in FIG. 11 and ends the contract status confirmation process shown in FIG.
