  Hereinafter, an embodiment of the present invention will be described in detail.

FIG. 1 is an example of a configuration diagram of a pair license issuing system according to an embodiment.
For example, the pair license issuance system includes an information processing device 1, an information processing device 2, a server 3, and a server 4, and the information processing device 2 is transferred to and shared with the license A acquired by the information processing device 1. A license B is issued, and the use of the content C is permitted by combining the license A (or license B) and the license As. Further, the server 3 and the server 4 may be configured by cooperation of a plurality of servers. Devices such as the information processing devices 1 and 2 and the servers 3 and 4 are connected to a network system such as the Internet 10 and include a computer unit having a CPU, a ROM, a RAM, a storage device, an input / output unit, a communication unit, and the like.

  For example, each of the information processing apparatuses 1 and 2 includes an electronic mail unit, a short-range wireless communication unit, an infrared communication unit, a public key Km, and the same user, two users, a user and an electronic commerce site, or The information processing apparatus 1 is assigned identification information Ia for identifying the user, the electronic commerce site, or the information processing apparatus 1, and the information processing apparatus 2 is used by the user, the electronic commerce site or the information. Identification information Ib for identifying the processing device 2 is assigned, the server 3 includes a public key cryptosystem secret key Ks and a public key Km, and the server 4 includes a public key cryptosystem secret key Kss and a public key Kmm.

  For example, the license A includes the pair information N, the license identifier I, the identification information Ia, the content identifier Ic, the expiration date D, the public key Kmm, and the like, and is encrypted with the secret key Ks. The license B is the pair information N, the license identifier I, The identification information Ib, the content identifier Ic, the expiration date D and the public key Kmm are included and encrypted with the secret key Ks, the license As is encrypted with the secret key Kss including the pair information N and the license identifier I, and the content C is The content identifier Ic and the like, the license A and the license As and the license B and the license As constitute a pair license, and the pair information N is information for pairing the license A and the license As and the license B and the license As (example) : Random number, serial number).

FIG. 2 is an example of a sequence flowchart of the pair license issuing system of the embodiment.
≪License issuance≫
First, the information processing apparatus 1 downloads the content C from a digital content distribution site (not shown) related to the server 4 and stores it in its storage device, obtains the content identifier Ic of the content C, and obtains the identification information Ia and the content The identifier Ic is transmitted to the server 4 to request a license (step S01). In response to the license request (step S02), the server 4 sends the identification information Ia, the content identifier Ic, and the public key Kmm to the server 3 to request the license A (step S03). In response to the request for license A (step S04), server 3 generates pair information N, license identifier I, and expiration date D, issues license A based on the received information and the generated information, The combination of the identifier I and the identification information Ia is stored in its own storage device and the license A is registered (step S05), and the pair information N, the license identifier I, and the license A are transmitted to the server 4 (step S06). In response to receiving the pair information N, the license identifier I, and the license A (step S07), the server 4 issues a license As (step S08), and transmits the license A and the license As to the information processing apparatus 1 (step S09). . In response to receiving license A and license As (step S10), information processing apparatus 1 stores license A and license As in its own storage device.

≪When providing content C for user use≫
The information processing apparatus 1 reads the license A, the license As, and the content C from its own storage device, decrypts the license A with the public key Km, decrypts the license As with the public key Kmm of the license A, As pair information N of As matches, license identifier I of license A and license As match, identification information Ia of license A and information processing device 1 matches, content of license A and content C Authentication of the license A and the license As confirming that the identifiers Ic match and the expiration date D of the license A has not passed is performed, and the content C is provided for use by the user.

  Here, the information processing apparatus 1 when the expiration date D of the license A has expired transmits the license A to the server 3 in order to request an update of the expiration date D of the license A (step S11). Upon receipt of license A (step S12), server 3 decrypts license A with public key Km and confirms that the combination of license identifier I of license A and identification information Ia is stored in its own storage device. (However, if the confirmation cannot be obtained, the processing ends without response to the information processing apparatus 1), the expiration date D is generated, and the license A with the updated expiration date D is updated. Is transmitted (step S13) to the information processing apparatus 1 (step S14). In response to reception of the license A (step S15), the information processing apparatus 1 stores the license A in its own storage device so as to replace it, and provides the content C for use by the user.

≪Transfer or share license≫
The information processing apparatus 2 requests the information processing apparatus 1 to transfer or share the license (step S16). In response to the license transfer or sharing request (step S17), the information processing apparatus 1 reads the license A from its own storage device and transmits the license A to the server 3 to request transfer or sharing setting (step S18). ). In response to the transfer or sharing setting request (step S19), the server 3 decrypts the license A with the public key Km, and the combination of the license identifier I of the license A and the identification information Ia is stored in its own storage device. The license A is verified (however, if the confirmation cannot be obtained, the process ends without responding to the information processing apparatus 1), and the transfer or sharing setting including the license identifier I of the license A is set. The information is stored in its own storage device (step S20), and a setting completion notification is transmitted to the information processing device 1 (step S21). When transfer is set in step S20, the combination of license identifier I of license A and identification information Ia is deleted from the storage device of server 3. Thus, after the license is transferred, the expiration date D of the license A cannot be updated, and the same effect as when the license A is deleted from the information processing apparatus 1 can be obtained.

  Next, in response to the reception of the setting completion notification (step S22), the information processing apparatus 1 reads the license A, the license As, and the content C from its own storage device and transmits them to the information processing apparatus 2 (step S23). In response to receiving license A, license As, and content C (step S24), information processing apparatus 2 transmits license A and identification information Ib to server 3 (step S25). Upon receiving the license A and the identification information Ib (step S26), the server 3 decrypts the license A with the public key Km to obtain the license identifier I of the license A, and transfers or shares the data stored in its own storage device. Confirming that it matches the license identifier I included in the setting (however, if the confirmation cannot be obtained, the processing ends with no response to the information processing device 2), deletes the setting from its own storage device, An expiration date D is generated, a license B is issued based on the identification information Ib, each information of the decrypted license A, and the generated expiration date D, and the combination of the license identifier I and the identification information Ib is stored in its own storage device The license B is registered (step S27) and transmitted to the information processing apparatus 2 (step S28). In response to receiving the license B (step S29), the information processing apparatus 2 stores the license B, the license As, and the content C in its own storage device.

≪When providing content C for user use≫
The information processing apparatus 2 reads the license B, the license As, and the content C from its own storage device, decrypts the license B with the public key Km, decrypts the license As with the public key Kmm of the license B, As pair information N of As matches, license identifiers I of license B and license As match, identification information Ib of license B and information processing device 2 match, contents of license B and content C The license B and the license As that confirm that the identifiers Ic match and the expiration date D of the license B has not expired are authenticated, and the content C is provided for use by the user.

  Here, the information processing apparatus 2 when the expiration date D of the license B has expired transmits the license B to the server 3 in order to request an update of the expiration date D of the license B (step S30). Upon receiving license B (step S31), server 3 decrypts license B with public key Km and confirms that the combination of license identifier I and identification information Ib of license B is stored in its own storage device. (However, if the confirmation cannot be obtained, the process ends without responding to the information processing apparatus 2), the expiration date D is generated, and the license B with the updated expiration date D is updated. It is issued (step S32) and transmitted to the information processing apparatus 2 (step S33). In response to the reception of the license B (step S34), the information processing apparatus 2 stores the license B in its own storage device so as to replace it, and provides the content C for use by the user.

  In the above embodiment, the pair license issuance system is such that the device that has performed step S25 that actually requests transfer or sharing to the server 3 in FIG. Steps S18 to S22 are performed by operating the information processing apparatus 1, and the user transmits the license A, the license As, and the content C attached to an e-mail to a transfer destination or a sharing destination. Also good. Further, the server 3 or the server 4 may be the content C seller side. The pair information N may be generated by the server 4 and transmitted between step S03 and step S04 in FIG. When the server 4 constitutes a library or a rental shop, the rental date may be included in the license As. Further, a mechanism may be provided in which the server 4 requests the server 3 to delete information including an arbitrary license identifier I from the storage device of the server 3 at the end of lending, and causes the server 3 to delete the information. In addition, when an identifier for identifying a lending company is included in each license instead of the content identifier Ic, it is possible to provide a content lending method that allows the lending company to freely use a plurality of contents. Since the license B provides the same operation and effect as the license A, it is possible to transfer or share the license by regarding the license B as the license A. Further, if the number of shared licenses corresponding to the license identifier I is stored in the storage device of the server 3, the number of shared licenses can be limited by the server 3. The content identifier Ic is provided for the license A and the license B, but may be provided for the license As.

  Further, in the pair license issuing system, in FIG. 2, the server 4 transmits identification information for identifying itself or the issuer of the license As in step S03, and the server 3 receives and authenticates the identification information in step S04. A configuration in which identification information for identifying itself or the issuer of license A is transmitted in step S06, and the server 4 receives and authenticates the identification information in step S07, and both the server 3 and the server 4 authenticate the other party. It is good.

  Further, in FIG. 2, for example, the server 4 on the licensor side calculates and transmits various taxes related to the transaction of the content C or the issuance of the license As in step S03. The server 3 is configured to store the various taxes received by the licensor side in step S04 and stored in its own storage device, or, for example, the server 3 on the licensor side transacts or licenses the content C in step S06. For example, if the server 4 on the taxing authority side calculates and transmits various taxes related to the issuance of A and stores them in its storage device as various taxes received by the licensor in step S07, for example, Apply various taxes such as consumption tax, sales tax and customs tax from the sensor side to the taxing authority such as tax office and customs. It can be. In addition, when a license is issued across borders, for example, the server 3 set up by the Japanese taxing authority, the server 4 set up by the US licensor, and the information processing apparatus 1 in Japan, From the licensor side, various taxes related to the license issuance can be reported to the Japanese taxing authority side, and the content C cannot be used in the information processing apparatus 1 unless the tax return is completed. If the license A is not transferred or shared, the server 4 may issue a license As including the license A in step S08. In addition, if electronic money is sent when sending various taxes, the licensor can also pay the tax, or if the taxing authority charges the licensor when the taxing authority stores it in the storage device, the licensor It is also possible for the side to pay tax.

  Further, the license A or license As issued by the server 3 or server 4 on the taxing authority side is related to the transaction of the content C, or includes various taxes related to the issuance of the license As or the license A. It is good also as a structure which doubles as the tax return certificate or tax payment certificate which proves having paid tax. And if the licensor reports or pays various taxes to the overseas taxing authorities, it may be configured to receive tax reduction or tax exemption measures in Japan by submitting a tax declaration certificate or tax payment certificate to the domestic taxing authority. . Here, the tax declaration certificate or the tax payment certificate is issued together with the license A or the license As by the server 3 or the server 4 on the taxing authority side without being used as the license A or the license As, and the server 4 or the server on the licensor side. It is good also as a structure which transmits to 3. FIG.

  In the above description, the case where various control programs including the communication control program are stored in the ROM in advance has been described. However, the control program may be recorded on a storage medium readable by the computer unit. With this configuration, when the program is read from the storage medium by the computer unit and the computer unit executes processing according to the read program, the same operations and effects as those of the devices of the above-described embodiment can be obtained.

  Here, the storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HDD, an optical reading type storage medium such as CD, DVD or BD, or a magnetic storage type / optical such as MO. Any storage medium can be used as long as it is a computer-readable storage medium regardless of electronic, magnetic, optical, or other reading methods.

  Further, the control program can be downloaded, installed and executed via a network system such as the Internet or a LAN.
