Equipment authentication device

An equipment authentication device comprising:

• a third storage unit storing identification information and password information of user of equipment with respect to each piece of equipment authorized to establish a connection to a network;
• a fourth storage unit storing unique information of the equipment with respect to some pieces of equipment in the pieces of equipment;
• a third authentication unit judging, when accepting a network connection request together with identification information and password information of a user of the equipment and the unique information of the equipment from any one of pieces of the equipment via a communication device, whether or not a tuple of the identification information and the password information is coincident with a tuple of the identification information and the password information stored in said third storage unit;
• a status judging unit judging, when said third authentication unit judges that the tuples of the identification information and the password information are coincident with each other, whether an operation status is a registration required status in which the unique information of the equipment concerned should be registered or an authentication requires status in which an authentication process based on the unique information of the equipment concerned should be executed;
• a registration unit registering, when said status judging unit judges that the operation status is the registration required status, the unique information of the equipment concerned in said fourth storage unit;
• a fourth authentication unit judging, when said status judging unit judges that the operation status is the authentication required status, whether the unique information of the equipment concerned is coincident with any one of pieces of the unique information stored in said fourth storage unit;
• and
• a switchover unit setting, when said fourth authentication unit judges that the unique information is coincident with the other piece of unique information, the equipment concerned in a network communication-enabled status.

An equipment authentication program making a computer function as:

• first storage means storing a storage device with unique information of equipment with respect to some equipment in pieces of equipment authorized to establish a connection to a network;
• second storage means storing said storage device with identification information and password information of a user of the equipment with respect to the respective pieces of equipment;
• first authentication means judging, when accepting a network connection request together with the unique information of the equipment from any one of piece of the equipment via a communication device, whether or not the unique information is coincident with any one of pieces of unique information stored in said storage device;
• switchover means setting, when said first authentication means judges that the unique information is coincident with the other piece of unique information, the equipment concerned in a network communication-enabled status;
• second authentication means acquiring, when said first authentication means judges that the unique information is not coincident with the other piece of unique information, the identification information and the password information of the user from the equipment concerned, and judging whether or not a tuple of the identification information and the password information is coincident with a tuple of the identification information and the password information stored in said storage device;
• and
• registration means making, when said second authentication means judges that the tuples of the identification information and the password information are coincident with each other, said first storage means register the unique information of the equipment concerned in said storage device.

An equipment authentication program making a computer function as:

• third storage means storing a storage device with identification information and password information of user of equipment with respect to each piece of equipment authorized to establish a connection to a network;
• fourth storage means storing said storage device with unique information of the equipment with respect to some pieces of equipment in the pieces of equipment;
• third authentication means judging, when accepting a network connection request together with identification information and password information of a user of the equipment and the unique information of the equipment from any one of pieces of the equipment via a communication device, whether or not a tuple of the identification information and the password information is coincident with a tuple of the identification information and the password information stored in said storage device;
• status judging means judging, when said third authentication means judges that the tuples of the identification information and the password information are coincident with each other, whether an operation status is a registration required status in which the unique information of the equipment concerned should be registered or an authentication requires status in which an authentication process based on the unique information of the equipment concerned should be executed;
• registration means making, when said status judging means judges that the operation status is the registration required status, said fourth storage means register the unique information of the equipment concerned in said storage device;
• fourth authentication means judging, when said status judging means judges that the operation status is the authentication required status, whether the unique information of the equipment concerned is coincident with any one of pieces of the unique information stored in said storage device;
• and
• switchover means setting, when said fourth authentication means judges that the unique information is coincident with the other piece of unique information, the equipment concerned in a network communication-enabled status.
