no. 1 Embodiment approach
[0024] The first embodiment is an example in which information equivalent to the identification information of a household electrical appliance acquired via a server device is displayed (reported) on a display screen of a terminal device, and a household electrical appliance communicates with a household electrical appliance by a user. The registration operation corresponding to this display is used to obtain the information for comparison, and the information for comparison acquired by the household electrical appliance is compared with the identification information (or information equivalent thereto) of the household electrical appliance through the server device, thereby The user of the terminal device is registered in association with the home electric appliance. In addition, this embodiment mode can be implemented by various modification examples. These modified examples will be collectively described at the end of the first embodiment. In addition, an example in which ...
no. 2 Embodiment approach
[0154] Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that a temporarily generated random number is used instead of the preset identification information I2.
[0155] Figure 11 It is a block diagram showing the configuration of the household electrical appliance 100, the terminal device 200, and the server device 300 according to the second embodiment. In the present embodiment, the storage unit 130 of the household electrical appliance 100 does not store the identification information I2. Instead, the household electrical appliance 100 has a random number generator 190 .
[0156] The random number generator 190 temporarily generates a random number when the household electrical device 100 transitions to the registration mode. The random number only needs to be information of a certain number of digits with a low probability of accidental coincidence. The generated random number is an example of "first information"....
