電子機器２１は、第１の実施形態の電子機器２０が備える機能に加え、コンテンツをダウンロードする際に認証を行う機能を有する。具体的には、電子機器２１は、権利移譲サーバ３１および認証サーバ６０それぞれから認証情報を受信し、両者の認証情報が一致するか否か判断する。判断の結果、一致すると判断した場合には、電子機器２１は、権利移譲サーバ３１からコンテンツをダウンロードする。一致しないと判断した場合には、権利移譲サーバ３１からコンテンツをダウンロードしない。 The electronic device 21 has a function of performing authentication when downloading content in addition to the function of the electronic device 20 of the first embodiment. Specifically, the electronic device 21 receives the authentication information from each of the right transfer server 31 and the authentication server 60, and determines whether or not the authentication information of both coincides. As a result of the determination, if it is determined that they match, the electronic device 21 downloads the content from the right transfer server 31. If it is determined that they do not match, the content is not downloaded from the right transfer server 31.

認証サーバ６０は、権利移譲サーバ３１から電子機器２１のＩＰアドレスを受信すると、認証情報を発行する。そして、認証サーバ６０は、受信したＩＰアドレスに基づいて、発行した認証情報を電子機器２１および権利移譲サーバ３１に送信する。ここで、認証情報は、電子機器２１がコンテンツをダウンロードする際の認証に用いられ、例えば、機器ＩＤとワンタイムパスワードとにより構成される。 Upon receiving the IP address of the electronic device 21 from the right transfer server 31, the authentication server 60 issues authentication information. Then, the authentication server 60 transmits the issued authentication information to the electronic device 21 and the right transfer server 31 based on the received IP address. Here, the authentication information is used for authentication when the electronic device 21 downloads content, and includes, for example, a device ID and a one-time password.

認証情報要求部３０５は、認証サーバ６０に電子機器２１のＩＰアドレスを送信し、認証情報を要求する。そして、認証情報要求部３０５は、認証サーバ６０から認証情報を取得する。 The authentication information request unit 305 transmits the IP address of the electronic device 21 to the authentication server 60 and requests authentication information. The authentication information request unit 305 acquires authentication information from the authentication server 60.

ダウンロード要求部３０６は、認証情報要求部３０５にて取得した認証情報を、取得部３０３にて取得されたコンテンツとともに電子機器２１に送信する。そして、電子機器２１にて、権利移譲サーバ３１および認証サーバ６０それぞれから受信した認証情報が一致すると判断された場合に、送信したコンテンツが電子機器２１にダウンロードされる。 The download request unit 306 transmits the authentication information acquired by the authentication information request unit 305 to the electronic device 21 together with the content acquired by the acquisition unit 303. When the electronic device 21 determines that the authentication information received from each of the right transfer server 31 and the authentication server 60 matches, the transmitted content is downloaded to the electronic device 21.

以上説明したように、本実施形態によれば、電子機器２１がコンテンツをダウンロードする際に認証を行うことにより、コンテンツが不正にダウンロードされることを防止することができる。 As described above, according to the present embodiment, it is possible to prevent content from being illegally downloaded by performing authentication when the electronic device 21 downloads the content.

＜第３の実施形態＞

As illustrated in FIG. 5, the right transfer system 3 according to the third embodiment includes a terminal 11, an electronic device 22, a return destination terminal 70, a right transfer server 32, and a user information management server 40.

第３の実施形態に係る各装置の機能について、図５とともに、図６に示す第３の実施形態に係る権利移譲サーバ３２の構成を示す機能ブロック図を用いて説明する。なお、第１および第２の実施形態と同一の符号を付す構成要素については、同一の機能を有することから、その詳細な説明は省略する。 The function of each device according to the third embodiment will be described with reference to FIG. 5 and a functional block diagram showing the configuration of the right transfer server 32 according to the third embodiment shown in FIG. In addition, about the component which attaches | subjects the code | symbol same as 1st and 2nd embodiment, since it has the same function, the detailed description is abbreviate | omitted.

端末１１は、通信機能を有する端末であって、ユーザが利用し、コンテンツを返却する際の契機となる通信を行う。第３の実施形態においても第１の実施形態の端末１０と同様に、端末１１は携帯電話機とする。また、端末１１は、電子機器２２が有するコンテンツのリストを、電子機器２２と共有する。これにより、ユーザは、返却するコンテンツを端末１１により指定することができる。 The terminal 11 is a terminal having a communication function, and performs communication used as a trigger when the user returns content. Also in the third embodiment, similarly to the terminal 10 of the first embodiment, the terminal 11 is a mobile phone. Further, the terminal 11 shares a list of contents that the electronic device 22 has with the electronic device 22. Thereby, the user can specify the content to be returned by the terminal 11.

端末１１は、返却先端末７０への通信要求、例えば、返却先端末７０へ電話をかける操作をユーザから受け付けると、返却先端末７０に自己の端末情報（以下、端末情報とする）を送信し、電子機器２２に、端末情報および返却先端末７０の端末情報（以下、返却先端末情報とする）を送信する。なお、電子機器２２への送信のタイミングは、返却先端末７０への送信と同時であってもよい。また、端末１１は、リストに基づいて、返却するコンテンツがユーザから指定された場合には、電子機器２２にコンテンツＩＤを送信する。 When the terminal 11 accepts a communication request to the return destination terminal 70, for example, an operation for making a call to the return destination terminal 70 from the user, the terminal 11 transmits its own terminal information (hereinafter referred to as terminal information) to the return destination terminal 70. The terminal information and the terminal information of the return destination terminal 70 (hereinafter referred to as return destination terminal information) are transmitted to the electronic device 22. Note that the transmission timing to the electronic device 22 may be simultaneous with the transmission to the return destination terminal 70. Further, the terminal 11 transmits a content ID to the electronic device 22 when the content to be returned is designated by the user based on the list.

電子機器２２は、ユーザがダウンロードしたコンテンツを有する機器である。電子機器２２は、端末情報および返却先端末情報を端末１１から受信すると、端末情報、返却先端末情報、自己の機器ＩＤ、および自己のＩＰアドレスを権利移譲サーバ３２に送信する。なお、端末１１からコンテンツＩＤを受信した場合には、受信したコンテンツＩＤも権利移譲サーバ３２に送信する。また、電子機器２２は、権利移譲サーバ３２から利用制御要求を受信すると、有するコンテンツを利用不可にする。コンテンツを利用不可にするとは、電子機器２２のユーザがコンテンツを利用できなくすることであり、コンテンツを削除することや、コンテンツへのアクセス権限を失くすことである。 The electronic device 22 is a device having content downloaded by the user. When receiving the terminal information and the return destination terminal information from the terminal 11, the electronic device 22 transmits the terminal information, the return destination terminal information, its own device ID, and its own IP address to the right transfer server 32. When the content ID is received from the terminal 11, the received content ID is also transmitted to the right transfer server 32. In addition, when the electronic device 22 receives the usage control request from the right transfer server 32, the electronic device 22 disables the content it has. Making the content unusable means that the user of the electronic device 22 cannot use the content, that is, deleting the content or losing access authority to the content.

返却先端末７０は、通信機能を有する端末であって、コンテンツ返却先が使用する端末である。コンテンツ返却先は、例えば、コンテンツサービス事業者である。端末１１から端末情報を受信すると、端末情報、および返却先端末情報を権利移譲サーバ３２へ送信する。 The return destination terminal 70 is a terminal having a communication function and used by the content return destination. The content return destination is, for example, a content service provider. When terminal information is received from the terminal 11, the terminal information and the return destination terminal information are transmitted to the right transfer server 32.

権利移譲サーバ３２は、コンテンツサービス事業者が管理するサーバであって、コンテンツを利用する権利を移譲するサーバである。図６に示すように、権利移譲サーバ３２は、判定部３０７、機器照会部３０１、削除部３０８、利用制御要求部３０９、および貸出情報記憶部３０４を備える。ただし、図示しないが、各部は送受信部を介して返却先端末７０などと情報の送受信を行っている。 The right transfer server 32 is a server that is managed by the content service provider, and that transfers the right to use the content. As shown in FIG. 6, the right transfer server 32 includes a determination unit 307, a device inquiry unit 301, a deletion unit 308, a usage control request unit 309, and a lending information storage unit 304. However, although not illustrated, each unit transmits and receives information to and from the return destination terminal 70 and the like via the transmitting and receiving unit.

判定部３０７は、返却先端末７０から受信した端末情報および返却先端末情報と、電子機器２２から受信した端末情報および返却先端末情報と、が一致するか否か判定する。判定の結果、一致する場合には、電子機器２２が、端末１１から返却先端末７０に返却要請されたコンテンツを有する機器であると判定する。一方、一致しない場合には、電子機器２２が、返却要請されたコンテンツを有さない機器であると判定する。電子機器２２が返却要請されたコンテンツを有さない機器と判定された場合には、後述する削除部３０８により貸出情報記憶部３０４が更新されない。この場合、端末１１や電子機器２２に、コンテンツが返却できない旨の通知を行ってもよい。 The determination unit 307 determines whether the terminal information and return destination terminal information received from the return destination terminal 70 match the terminal information and return destination terminal information received from the electronic device 22. If they match as a result of the determination, it is determined that the electronic device 22 is a device having the content requested to be returned from the terminal 11 to the return destination terminal 70. On the other hand, if they do not match, it is determined that the electronic device 22 is a device that does not have the content requested to be returned. When it is determined that the electronic device 22 does not have the requested content, the lending information storage unit 304 is not updated by the deletion unit 308 described later. In this case, you may notify the terminal 11 and the electronic device 22 that content cannot be returned.

削除部３０８は、貸出情報記憶部３０４に記憶されている端末情報のうち、電子機器２２から受信した端末情報を削除する。これにより、コンテンツを利用する権利を、ユーザからコンテンツ返却先に移譲することができる。なお、削除部３０８は、端末１１から受信した端末情報を用いてもよい。また、貸出情報記憶部３０４において、電子機器２２から受信した端末情報を、返却先端末７０の端末情報に書き換えてもよい。さらに、電子機器２２からコンテンツＩＤを受信した場合には、貸出情報記憶部３０４においてコンテンツＩＤに対応付けられている端末情報のうち、電子機器２２から受信した端末情報を削除する。 The deletion unit 308 deletes the terminal information received from the electronic device 22 among the terminal information stored in the lending information storage unit 304. Thereby, the right to use the content can be transferred from the user to the content return destination. Note that the deletion unit 308 may use terminal information received from the terminal 11. In the lending information storage unit 304, the terminal information received from the electronic device 22 may be rewritten with the terminal information of the return destination terminal 70. Further, when the content ID is received from the electronic device 22, the terminal information received from the electronic device 22 is deleted from the terminal information associated with the content ID in the lending information storage unit 304.

利用制御要求部３０９は、電子機器２２から受信したＩＰアドレスに基づいて、利用制御要求を電子機器２２に送信する。 The usage control request unit 309 transmits a usage control request to the electronic device 22 based on the IP address received from the electronic device 22.

＜権利移譲システムの処理フロー＞

次にステップＳ４において、権利移譲サーバ３０の判定部３０７は、電子機器２２および返却先端末７０それぞれから受信した、端末情報、および返却先端末情報が一致するか否か判断する。そして、一致する（ＹＥＳ）場合には、ステップＳ５に処理を移し、一致しない（ＮＯ）場合には、処理を終了する。 Next, in step S 4, the determination unit 307 of the right transfer server 30 determines whether the terminal information and the return destination terminal information received from the electronic device 22 and the return destination terminal 70 match each other. If they match (YES), the process proceeds to step S5. If they do not match (NO), the process ends.

次にステップＳ５において、権利移譲サーバ３０の機器照会部３０１は、電子機器２０から受信した機器ＩＤと端末情報とが対応付けて記憶されているかユーザ情報管理サーバ４０に照会することにより、電子機器２０が、端末１０により操作ができる電子機器であるか否か判断する。そして、機器照会部３０１が、電子機器２０が、端末１０により操作ができる電子機器であると判断する（ＹＥＳ）場合には、ステップＳ６に処理を移し、電子機器２０が、端末１０により操作ができない電子機器であと判断する（ＮＯ）場合には、処理を終了する。 In step S5, the device inquiry unit 301 of the right transfer server 30 inquires the user information management server 40 whether the device ID received from the electronic device 20 and the terminal information are stored in association with each other. It is determined whether 20 is an electronic device that can be operated by the terminal 10. If the device inquiry unit 301 determines that the electronic device 20 is an electronic device that can be operated by the terminal 10 (YES), the process proceeds to step S 6, and the electronic device 20 is operated by the terminal 10. If it is determined that the electronic device cannot be used (NO), the process ends.

次に、ステップＳ６において、削除部３０８は、貸出情報記憶部３０４に記憶されている端末情報のうち、電子機器２２から受信した端末情報を削除する。 Next, in step S 6, the deletion unit 308 deletes the terminal information received from the electronic device 22 among the terminal information stored in the lending information storage unit 304.

次に、ステップＳ７において、利用制御要求部３０９は、電子機器２２から受信したＩＰアドレスに基づいて、利用制御要求を電子機器２２に送信する。 Next, in step S 7, the usage control request unit 309 transmits a usage control request to the electronic device 22 based on the IP address received from the electronic device 22.

次に、ステップＳ８において、電子機器２２は、権利移譲サーバ３２から利用制御要求を受信すると、有するコンテンツを利用不可にする。 Next, in step S 8, when receiving the usage control request from the right transfer server 32, the electronic device 22 disables the content it has.

以上説明したように、本実施形態によれば、端末１１からコンテンツ返却先の返却先端末７０への通信を契機として、コンテンツサービス事業者が管理する権利移譲サーバ３２の貸出情報記憶部３０４を更新することにより、コンテンツの権利を、ユーザからコンテンツ返却先に移譲することができる。 As described above, according to the present embodiment, the lending information storage unit 304 of the right transfer server 32 managed by the content service provider is updated with the communication from the terminal 11 to the return destination terminal 70 of the content return destination.
