When the pointer frame 21 is moved on the program guide 15 to select a program and perform a reservation operation, program reservation information representing the reservation content is generated. This program reservation information is stored in a memory or HDD in the HDD / DVD recorder 11. Although not shown in detail, program reservation information is generated and stored in the same manner even when a recording reservation is made by e-mail or a network connection from a PC, and can be used for personal authentication.

  As shown in FIG. 4, the personal authentication device 6 is connected to the registered home appliance via the home LAN 5 by the network connection unit 31. For example, the HDD / DVD recorder 11 having the lowest registration number is connected first, and program reservation information and EPG information are acquired. When the control unit 30 compares the acquired program reservation information with the program reservation information stored in the storage unit 32 and determines that the program reservation information is new, the control unit 30 stores it in the storage unit 32.

  After the connection to the HDD / DVD recorder 11 is completed, it connects to the next home appliance, for example, the TV 10, the TV tuner, and the PC 12 with capture, and similarly acquires program reservation information and EPG information.

  As shown in FIG. 5, the personal authentication device 6 displays various menus such as “lock”, “unlock”, and “setting” on the monitor of the touch screen 33. When “unlock” is selected using the touch sensor, a menu of “password” and “program reservation information” is displayed on the monitor. The personal authentication device 6 can arbitrarily select one of personal authentication by inputting a general password and personal authentication using a TV program reservation as an authentication code.

  When the menu “password” is selected, the lock is released through a procedure of displaying a password input screen, accepting input of a password, and verification. If a password mismatch occurs, a warning is displayed on the monitor. Furthermore, when password mismatches occur, for example, three times in succession, password input is stopped.

  When “program reservation information” is selected in the menu “unlock”, the monitor displays a list of home appliances that can be used for personal authentication and the program reservation date, and accepts these selections. Thus, since the home appliance and the program reservation date can be selected, higher security performance can be obtained. In addition, since past program reservation dates can also be used for authentication, there is no problem even if no program reservation is made.

  For example, when the HDD / DVD recorder 11 is selected as the home appliance and “October 23” is selected as the program reservation date, the control unit 30 refers to the storage unit 32 and selects program reservation information corresponding to these selections. Set as an authentication code. Further, the control unit 30 specifies the order of reservation with reference to time stamps of a plurality of program reservation information set as authentication codes. In this way, since the reservation contents of the broadcast program can be used for the authentication code, there is no need to register the authentication code in advance. In addition, since the frequency of changing the authentication code increases, high security performance can be obtained.

  The touch screen 33 reads the EPG information corresponding to the program reservation information set as the authentication code from the storage unit 32, displays the program guide on the monitor based on this, and accepts the input of the program reservation information. Thus, since the program guide can be used when the program reservation information is input, the reservation details can be easily recalled.

  The control unit 30 collates the input program reservation information with the program reservation information set as the authentication code. If they match, the input order of the program reservation information is compared with the reservation order, and if they match, an authentication signal is output from the external device I / F 34. As a result, the door lock is released by the door lock device 7.

  If the program reservation information or input order does not match, a warning is displayed on the monitor. Further, when the program reservation information mismatch occurs, for example, three times in succession, the input is stopped. In this way, not only the reservation contents of the program but also the reservation order are collated, so that higher security performance can be obtained.

In the above embodiment, authentication by password and authentication by program reservation information can be selected, but authentication may be performed only by program reservation information. Further, the program reservation information and the input order are collated, but the collation by the input order may be omitted. Furthermore,
Although an example in which a personal authentication device is used for home security has been described, it can also be used for other personal authentication.
