Problems solved by technology

[0004] However, the license key is usually generated based on the unique information of the device (serial number, etc.), and in a system where multiple devices operate in cooperation, if the effective functions of each device are different, the system may malfunction.
In order to prevent this, it is necessary to issue a license key for each device and register it in the device, and the key issuance operation and the key input operation need to be performed as many times as the number of devices, which is very complicated

no. 2 Embodiment approach 》

[0091] Figure 4 The overall configuration of the network system 201 according to the second embodiment of the present invention is shown. The main difference between this embodiment and the first embodiment is that authentication is requested to the center when the second license key is generated, and slave-specific information is acquired from the master.

[0092]

[0093] Such as Figure 4 As shown, the structure of the network system 201 is the same as that of the first embodiment, and is mainly composed of a device 210 and a center 220, wherein the device 210 is composed of a plurality of devices, and is used to make the functions of each device effective, and the center 220 is used to distribute Licensor of the license key that enables the feature. The device 210 is managed by a user, and is installed so as to be able to communicate with the center 20 via a network or the like.

[0094] Similar to the first embodiment, in the center 220, when receiving a user's purc...

Abstract

An apparatus (10) is an apparatus including a plurality of devices and configured to enable a specified function of a first device (11) among the plurality of devices by a first license key distributed by a licenser (20). The apparatus (10) includes a key input unit (13a) and a key generation unit (11b). The key input unit (13a) allows the first license key to be input. A second license key is generated based on the first license key and specific information on a second device (12) among the plurality of devices. The apparatus (10) further enables the specified function of the second device (12) by the second license key. Accordingly, it is possible to easily and reliably enable a function of each device of an apparatus by a single license key, even if the apparatus includes a plurality of devices.

Description

technical field [0001] The present invention relates to a device, a network system, a method and a computer program for validating functions of a plurality of devices. Background technique [0002] Conventionally, for the purpose of software copyright protection or separately selling optional functions, a method has been adopted in which a complete set of programs is preinstalled on a device, and only necessary functions are enabled by inputting a license key or the like during use (for example, Patent Document 1, etc.). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2002-163505 [0004] However, the license key is usually generated based on the unique information of the device (serial number, etc.), and in a system in which multiple devices operate in cooperation, if the effective function of each device is different, the system may malfunction. In order to prevent this, it is necessary to issue a license key for each device and register it in the device, and th...
