When a request for using a service on the network 300 is transmitted from the client device 100, the network device 200 performs data transfer between the client device 100 and the network 300. By doing so, the client device 100 can use the service via the network device 200.

  In the communication system 10 shown in FIG. 1, when the client device 100 inputs that the service on the network 300 is to be used, the client device 100 establishes communication with the network device 200 via the wireless LAN, and A use request is transmitted to the network device 200. The network device 200 allows the client device 100 to use the service in response to the use request.

  Here, in order to establish communication with the network device 200 via the wireless LAN, it is necessary to set information such as an SSID (Service Set Identifier) in the client device 100. Hereinafter, information that needs to be set in the client device 100 in order to establish communication with the network device 200 via the wireless LAN is referred to as setting information.

  Also, unauthorized use of services based on ISP authentication information such as IDs and passwords assigned by ISPs that provide services on the network 300, or site information indicating harmful sites that contain harmful information. Is prevented. Hereinafter, information for preventing unauthorized use of services and ensuring security, such as ISP authentication information and site information, will be referred to as security information.

  In the present embodiment, a QR code 400 in which setting information and security information for using a service via the network device 200 are coded in advance is provided corresponding to the network device 200. Here, the QR code 400 is affixed to the network device 200 with a sticker or the like and presented to the user, or distributed to a user who has authority to use the service.

  QR code 400 is assigned by an ISP operator when a network device such as a router is rented out to a user who has made a service use contract by an ISP operator and a LAN is formed in the user's home. Authentication information and site information indicating a harmful site that restricts browsing set at the time of use contract are encoded and generated.

  Next, the operation of the client device 100 when using the service will be described with reference to the flowchart shown in FIG. In FIG. 3, description will be given using an example in which the security information is ISP authentication information assigned to the network device 200. In the following, it is assumed that setting information and ISP authentication information included in the QR code 400 of the network device 200 are already stored in the storage unit 120.

  When the security processing unit 142 detects an input to use a service on the network 300 via the network device 200 (step S31), the security processing unit 142 reads setting information and ISP authentication information corresponding to the network device 200 from the storage unit 120 ( Step S32).

  Next, the security processing unit 142 establishes communication with the network device 200 based on the setting information read to the wireless LAN interface unit 130 (step S33).

  Next, the security processing unit 142 transmits a service use request including the read ISP authentication information to the network device 200 via the wireless LAN interface unit 130 (step S34).

  The network device 200 transfers the service use request transmitted from the client device 100 to the ISP provider side. On the ISP provider side, authentication is performed based on the ISP authentication information, and if the authentication is successful, the client device 100 can use the service.

  As described above, the ISP apparatus includes the ISP authentication information in the QR code 400, and the client apparatus 100 transmits a service use request including the ISP authentication information obtained by photographing and reading the QR code 400 to the network apparatus 200. The service can be used without setting ISP authentication information.

  Although the example in which the security information is ISP authentication information has been described with reference to FIG. 3, the present invention is not limited to this.
