1. Field of the Invention
The present invention relates to a server apparatus and an information processing system. More specifically, the present invention relates to a server apparatus and an information processing system, which perform a copy permission management of a content recorded in a medium such as a disc for rental.
2. Description of the Related Art
In recent years, there have been utilized many DVDs (Digital Versatile Discs), BDs (Blu-ray Discs (registered trademark)), and the like as information recording media (media) of various contents such as movies and music. Regarding most of the contents such as music data, image data, and the like which are recorded in the information recording media, the creators, the buyers, or the like have copyright or distribution right. Therefore, even on a user who has purchased the disc, there is predetermined limitation for using contents recorded in the disc. For example, it is not allowed for the user to copy the contents recorded in the disc in a medium such as another disc without limitation.
As a copy control configuration for the contents stored in the medium as described above, there has been known a copy allowance process configuration using reception of copy permission information from a management server as a condition. Specifically, processes are performed in the following sequence.
The user mounts a medium such as a content-storing disc to user's apparatus such as a PC or a recording/reproducing apparatus, and the user's apparatus is connected via a network to the management server. After that, the user's apparatus transmits information defined in advance, such as a disc identifier (ID), to the server. After the server confirms legitimacy or the like of the received information, the server transmits copy permission information to the user's apparatus. The user's apparatus is capable of starting a copy process, using the reception of the copy permission information from the server as the condition thereof.
The above-mentioned copy control configuration is called a managed copy (MC), and the details thereof are described, for example, in Japanese Patent Application Laid-open No. 2008-98765.
On the other hand, there has been an AACS (Advanced Access Content System) standard as a standard relating to a copyright protection technique for contents. Most of contents recorded in the disc such as BDs according to AACS standard are recorded as encrypted contents. As a typical encryption configuration in AACS standard, there has been a configuration in which a content is divided into units and different encryption keys are applied for the respective units. By employing the above-mentioned encryption configuration, use managements for the content in units are allowed, to thereby achieve strict and various content use managements.
The managed copy (MC) is being under consideration as a mechanism for permitting copying with respect to a content that the user has purchased in an operation thereof. However, in recent years, in the distribution field for media in which contents are recorded, there have been more and more occasions where digital contents are provided to end users in a rental form. In the above-mentioned situation, there is a case where a user wants to save a copy of a content in a medium for user when the user likes the content after viewing the content stored in the medium that the user has rented.
In view of the circumstances as described above, there is a need for providing a server apparatus and an information processing system, which are capable of performing a copy permission management of a content recorded in a medium for rental.
According to an embodiment of the present invention, there is provided a server apparatus including a first payment-information transmitting and receiving unit and a copy-permission-information providing unit. The first payment-information transmitting and receiving unit transmits and receives, via a network with respect to an information processing apparatus capable of reproducing a medium for rental in which a content protected from copying is recorded, information about payment necessary for obtaining a copy permission of a content recorded in the medium. The copy-permission-information providing unit provides information of permitting copying of the content via the network to the information processing apparatus every time when the copy-permission-information providing unit confirms completion of the payment through the transmission and reception of the information about the payment with respect to the information processing apparatus of the user.
According to the embodiment of the present invention, it is possible to provide a service that if a user likes the content of the medium for rental after viewing, the user is allowed to copy that content through paying a predetermined fee.
The first payment-information transmitting and receiving unit may transmit and receive payment data as the information about the payment with respect to the information processing apparatus of the user. Further, the copy-permission-information providing unit may perform a payment process through the transmission and reception of the payment data, and may provide the information of permitting the copying of the content via the network to the information processing apparatus when the copy-permission-information providing unit confirms the completion of the payment process.
The first payment-information transmitting and receiving unit may receive, from the information processing apparatus of the user, authentication information indicating the completion of the payment as the information about the payment. Further, the copy-permission-information providing unit may determine legitimacy of the authentication information indicating the completion of the payment, and may provide the information of permitting the copying of the content via the network to the information processing apparatus when the copy-permission-information providing unit determines that the authentication information is legitimate.
According to another embodiment of the present invention, there is provided an information processing system including an information processing apparatus of a user and a sever apparatus. The information processing apparatus includes a second payment-information transmitting and receiving unit and a copy process unit. The second payment-information transmitting and receiving unit transmits and receives, via a network with respect to the sever apparatus, information about payment necessary for obtaining a copy permission of a content of a medium for rental in which the content protected from copying is recorded. The copy process unit obtains information of permitting copying of the content via the network from the server apparatus and records a copy of the content of the medium for rental in a medium for user, to thereby perform the copying of the content. The server apparatus includes a first payment-information transmitting and receiving unit and a copy-permission-information providing unit. The first payment-information transmitting and receiving unit transmits and receives with respect to the information processing apparatus via the network the information about payment. The copy-permission-information providing unit provides the information of permitting copying of the content via the network to the information processing apparatus every time when the copy-permission-information providing unit confirms completion of the payment through transmission and reception of the information about the payment with respect to the information processing apparatus.
As described above, according to the embodiments of the present invention, it is possible to perform the copy permission management of the content stored in the medium for rental.
These and other objects, features and advantages of the present invention will become more apparent in light of the following detailed description of best mode embodiments thereof, as illustrated in the accompanying drawings.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
This embodiment relates to a managed copy (MC) process to be applied in a case where a content stored in a medium for rental, which a user has rented from a rental agency, with the content being protected from copying, is copied in a medium for user through an information processing apparatus of the user.
The rental agency 20 rents media 50 for rental including various titles from the content-providing agency 40, and pays the content-providing agency 40 a rental fee F1. A user U goes to a store of the rental agency 20, rents a medium 50 for rental having a title, that the user wants to view, from the rental agency 20, and pays the rental agency 20 a rental fee F2. In a case where the user U wants to use the information processing apparatus 10 to copy a content, which is recorded in the rented medium 50 and is protected from copying, in a medium 60 for user, the user U accesses via an Internet 1 (network 1) the management server 30 managing a copy permission and the like of that content. After transmission and reception of information necessary for obtaining a copy permission of the content, which, for example, include payment between the information processing apparatus 10 and the management server 30, the information processing apparatus 10 obtains copy permission information (Permission) from the management server 30, and uses this to record the content in the medium 60 for user being a copy destination. A copy fee F3, which is collected during the payment process between the management server 30 and the user of the information processing apparatus 10, is passed to the content-providing agency 40 through some means.
Here, the medium 50 for rental is supposed to be a BD (Blu-ray Disc (registered trademark)) or the like, and it is sufficient that the medium 50 for rental be a medium in which an encrypted content according to an AACS (Advanced Access Content System) standard being a standard relating to a copyright protection technique for contents is recorded. The encrypted content according to the AACS standard is divided into units, and recorded as encrypted data in which different encryption keys are applied for the respective units. With the encryption configuration in units, a use management for each unit is allowed, and rigid and various content use managements can be realized.
Next, the description will be made of a configuration of an information processing system for realizing a managed copy process of a content of this embodiment in a rental medium distributing process.
As shown in the figure, this information processing system 100 includes the information processing apparatus 10 to perform a process of reading a content from the medium 50 for rental and recoding the content in the medium 60 for user in which data can be recorded. In addition, the information processing system 100 includes the management server 30 to execute a providing process for permission information in this content copy process and management data.
Here, the medium 50 for rental is, for example, a ROM disc or a disc such as a Blu-ray Disc (registered trademark).
The medium 60 for user being the copy destination of the content is, for example, a recoding medium such as a hard disc (HDD), an R type or RE type Blu-ray Disc (registered trademark), or a DVD disc.
In the medium 50 for rental, a content 51 encrypted according to the AACS standard is recorded. The content 51 to be recorded includes, for example, an AV (Audio Visual) stream of a moving image content such as an HD (High Definition) movie content being high-definition moving image data, or music data, a game program, an image file, audio data, text data, and the like. The encrypted content is, for example, an encrypted content, which has a configuration with which a use management for each content management unit (CPS unit) can be performed, and in which different unit keys (CPS unit keys) are applied in the respective content management units (CPS units).
Further, in the medium 50 for rental, there are stored, as a copy-process managing file (MCMF) 52, a URI (URL) for specifying the management server 30 to be accessed when a copy permission of the content 51 is requested, a content ID (CID) serving as an identifier of the content 51, an ID of the content certificate (CC) (CCID) indicating legitimacy of the content 51, a PMSN (Pre-recorded Media Serial Number) serving as a medium identifier, and the like. In addition, in the medium 50 for rental, there is stored, as content-use managing data 53, a CCI (Copy Control Information) being copy/reproduction control information, and a CPS unit key being an encryption key to be set for each of the content management units (CPS units) being as content-use management units. In addition, there are stored an MKB (Media Key Block) being an encryption key block in which key information (medium 50 key) for obtaining a CPS unit key is stored, and the like.
In addition, in the medium 50 for rental, there are stored application programs (not shown) to be executed in the information processing apparatus 10 when a copy process of the content 51 is performed. The application programs includes an application program for executing a communication with respect to the management server 30, an application program dedicated to the payment process, and the like. When copying of the content 51 is executed, those application programs are executed in the information processing apparatus 10.
The information processing apparatus 10 is, specifically, a PC, a recording/reproducing apparatus, or the like, and includes computer hardware including a CPU to execute applications read from the medium 50 for rental, a main memory, and the like. The information processing apparatus 10 is provided with a copy-permission-request processing unit (second payment-information transmitting and receiving unit) 11 to transmit and receive, via the network 1 with respect to the management server 30, various information including information about payment, which is necessary for obtaining a copy permission of the content 51 by the applications and the computer hardware. In addition, in the information processing apparatus 10, there is provided a recording unit 12 (copy process unit) to read the content 51 from the medium 50 for rental and record the content 51 in the medium 60 for user being the copy destination.
Regarding the managed copy process, the copy-permission-request processing unit 11 executes the following processes.
The management server 30 is, specifically, a PC or the like, and includes computer hardware including a CPU to execute an application program for performing a permission management for copying the content 51 recorded in the medium 50 for rental, a main memory, and the like. For this, a copy-permission-management executing unit 31 (first payment-information transmitting and receiving unit, copy-permission-information providing unit) of the management server 30 is provided.
The copy-permission-management executing unit 31 executes, more specifically, the following processes.
Next, the description will be made of the managed copy process between the information processing apparatus 10 and the management server 30 with reference to
The information processing apparatus 10 checks, first, whether the PMSN being as the medium identifier is recorded in Burst Cutting Area of the medium 50 for rental (
When the management server 30 receives the copy allowance list request (Offer Request) (
In a case where the content is the content that needs legitimacy check by the PMSN in determination of the copy permission (
On the other hand, in a case where it is determined in Step S204 that the PMSN is legitimate (
When the information processing apparatus 10 obtains the copy allowance list (Offer List) from the management server 30, the information processing apparatus 10 displays the copy allowance list (Offer List) on the display (
When the payment process necessary for obtaining the copy permission is terminated without problem between the information processing apparatus 10 and the management server 30 (
When the management server 30 receives the copy permission request (Permission Request) from the information processing apparatus 10 (
When the information processing apparatus 10 obtains the copy permission information (Permission) from the management server 30 (
As described above, in this embodiment, the managed copy process is introduced in the distribution process for the rental media in which contents protected from copying are recorded, and hence, if a user likes the content of the medium 50 for rental after viewing, the user is allowed to copy that content through paying a predetermined fee. With this, it is possible to achieve an increase of total content users including rentals, an increase of occasions in which the managed copy is utilized, and the like, and hence further development in the content distributing industry can be expected.
Further, in this embodiment, while copyrights to be rented can be managed and protected, a user who has rented the medium 50 additionally obtains (pursues) the content that the user wants to have after viewing. With this, it is possible to further enhance convenience for users who utilize rental services.
By the way, according to the managed copy process of this embodiment, even if a user who has rented the medium 50 from the rental agency 20 lends it to a different user for free, and the different user wants to save a copy of the content recorded in the medium 50, the different user can obtain copy permission information from the management server 30 in the above-mentioned manner, to thereby save the copy of the content.
That is, in the management server 30, if the PMSN is legitimate and completed payment with respect to the information processing apparatus 10 of the user can be confirmed, the copy permission is provided. With this system, it is possible to realize managed copy services suitable for the medium 50 for rental, the copy permission list requests of which are expected to be transmitted by the same PMSN to the management server 30 many times.
Further, in rental business in the past, renting between users are generally forbidden by contract because it may cause troubles such as long-overdue rental or loss and further it may deteriorate profits of the rental agencies. In contrast, in this embodiment, even if the rental agencies allow renting between the users, the rental agencies can separately increase the profits. As a result, free distribution of the media for rental between the users can be realized, and it is possible to further enhance convenience for the users who utilize rental services.
This embodiment is an embodiment in which it is assumed that in the managed copy process to be applied in the case where the content stored in the medium for rental, which the user has rented from the rental agency, with the content being protected from copying, is copied on the medium for user through the information processing apparatus of the user, the user performs payment with respect to not the management server, but the rental agency.
The rental agency 20 rents media 50 including various titles from the content-providing agency 40, and pays the content-providing agency 40 a rental fee F1. A user U goes to a store of the rental agency 20, rents a medium 50 of a title, that the user wants to view, from the rental agency 20, and pays the rental agency 20 a rental fee F2. At this time, in a case where the user U wants to copy a content, which is stored in the above-mentioned medium 50, in a medium 60 for user, the user U informs the rental agency 20 accordingly, to thereby pursue a copyright thereof. The copyright is provided in such a manner that the user U is notified of a code B (hereinafter, referred to as “voucher code”) issued by the rental agency 20. The voucher code B is, for example, a code issued with respect to the rental agency 20 from the management server 30A in advance, and all codes are desirably unique codes. In the management server 30A, the issued voucher codes are managed while being each associated with the content ID (CID) and the content certificate ID (CCID) of the corresponding content. In a case where the user U wants to use the information processing apparatus 10A to copy a content recorded in the medium 50, that the user U has rented, in the medium 60 for user, the user U accesses the management server 30A managing a copy permission thereof and the like via the Internet 1. After transmission and reception of information necessary for obtaining a copy permission of the content, which, for example, include payment between the information processing apparatus 10A and the management server 30A, the information processing apparatus 10A obtains copy permission information (Permission) from the management server 30A, and uses this to record the content in the medium 60 for user.
Next, the description will be made of a configuration of an information processing system for realizing a managed copy process of a content of this embodiment in a rental medium distributing process.
Here, the configuration of the medium 50 for rental is the same as that of the first embodiment except for an application program recorded therein. In the information processing apparatus 10A, there is provided a copy-permission-request processing unit (second payment information transmitting and receiving unit) 11A to transmit and receive information necessary for obtaining a copy permission of the content 51 by use of the above-mentioned application and computer hardware via the network 1 with respect to the management server 30. In addition, in the information processing apparatus 10, a recording unit 12A to read from the medium 50 for rental the content 51 and record the content 51 in the medium 60 for user being the copy destination is provided.
Regarding the managed copy process, the copy-permission-request processing unit 11A executes the following processes.
The management server 30A includes computer hardware including a CPU to perform an application program for performing a permission control for copying the content 51 recorded in the medium 50 for rental, a main memory, and the like. For this, a copy-permission-management executing unit 31A (first payment-information transmitting and receiving unit, a copy-permission-information providing unit) of the management server 30A is provided.
The copy-permission-management executing unit 31A executes, more specifically, the following processes.
Next, the description will be made of the managed copy process between the information processing apparatus 10A and the management server 30A with reference to
The information processing apparatus 10A transmits, first, from the copy-process managing file (MCMF) stored in the medium 50 for rental, the copy allowance list request (Offer Request) including the content ID (CID) and the content certificate ID (CCID) to the management server 30A (
When the management server 30A receives the copy allowance list request (Offer Request) (
The management server 30A determines, based on the obtained the content ID (CID) and content certificate ID (CCID), whether the content is a content corresponding to a managed copy by the voucher code. The management server 30A manages the list of content IDs (CID) and content certificate IDs (CCID) of contents corresponding to a managed copy by the voucher code, and is set to add a content ID (CID) of a content having a title rented to the rental agency 20 to the list. The management server 30A performs matching between the list, and the content ID (CID) and the content certificate ID (CCID) included in the copy allowance list request (Offer Request) from the information processing apparatus 10A, and determines whether it is the content corresponding to the managed copy by the voucher code. In a case where it is determined that it is the content corresponding to the managed copy by the voucher code, the management server 30A sets, in the copy allowance list (Offer List), a flag (voucher code valid flag) indicating that it is the content corresponding to the managed copy by the voucher code for each of the files constituting the content. The management server 30A transmits the copy allowance list (Offer List) thus generated to the information processing apparatus 10A (
When the information processing apparatus 10A obtains from the management server 30A the copy allowance list (Offer List), the information processing apparatus 10A displays the copy allowance list (Offer List) on the display (
On the other hand, in a case where the voucher code valid flag is set (
In the management server 30A, the voucher codes already issued are managed in a table while being each associated with the content ID (CID) and the content certificate ID (CCID) of the content. When the management server 30A obtains through the information processing apparatus 10A the voucher code (
When the information processing apparatus 10A receives the notification of the success of the authentication of the voucher code from the management server 30A (
When the management server 30A receives the copy permission request (Permission Request) from the information processing apparatus 10A (
When the information processing apparatus 10A obtains from the management server 30A the copy permission information (Permission) (
Further, in a case where the voucher code is not transmitted, or in a case where it is determined as an illegitimate voucher code (for example, also including a case where the number of copying allowed for one voucher code is consumed) (
In addition, the information processing apparatus 10A receives the notification from the management server 30A in Step S307 that the authentication of the voucher code is failed, the information processing apparatus 10A terminates the process as a result of the copy permission of the content being not obtained.
As described above, in this embodiment, the managed copy process using the voucher code is introduced in the distribution process for the rental media in which contents protected from copying are recorded, and hence, if a user likes the content of the medium 50 for rental after viewing, the user is allowed to copy that content through paying a predetermined fee. Further, in this embodiment, the payment process via the network 1 is unnecessary, and hence this embodiment has an advantage of being more excellent in security. That is an effect due to the fact that the distribution of media for rental is basically performed through agencies.
In this modified example, there is employed a mode in which the rental agency 20B operates also services of the managed copy process by the management server 30B. Also in this case, it is possible to employ the method for the copy permission management of the contents of the media 50 for rental according to the first embodiment and the second embodiment, which are described above.
It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
