The code file output unit 51 is a unit that outputs the code file generated by the code file generation unit 50 to the memory card control unit 9 or the communication device 10.

[Action]
An example of the search processing according to the present embodiment as described above will be described with reference to the flowchart of FIG. 2 and the explanatory diagrams of FIGS. The user operates the operation input unit 8 in advance to register authentication information such as a password and identification information such as an address and a telephone number, thereby enabling the anti-theft function. These pieces of information are also registered and managed in a server of an authentication organization A (for example, an organization operated by a car navigation manufacturer). Further, the authentication organization A manages a user's handwritten paper describing the same contents in order to collate with a personal identification number inquiry paper described later.

[By regular user]
First, as shown in FIG. 3A, when a legitimate user removes the navigation device from the conventional vehicle C1 and attaches it to the new vehicle C2, the power detection unit 45 detects the power connection again (step). 201). Then, since the input request display instruction unit 46 instructs display of the input request screen, the input request screen is displayed on the display 6 as shown in FIG. 4 (step 202).

  On the other hand, when the user inputs a correct password using the operation input unit 8 (step 203), the authentication unit 48 determines whether the password registered in advance matches the entered password. (Step 210). In this case, since the correct password has been input, the permission unit 49 permits the use of the function of the navigation device N (step 211).

  On the other hand, when the user forgets the password, the user selects the code issue button by the operation input unit 8. Then, the input determination unit 47 determines that there is a code issue instruction (step 204). In response to this, the code file generation unit 50 acquires the vehicle position information at that time (step 205), and generates an encrypted code file F together with a pre-registered personal identification number and authentication information (step 206). .

  When the memory card is inserted in the slot in advance (step 207), the code file output unit 51 outputs the code file F to the memory card control unit 9 (step 208). As a result, the code file F is recorded in the memory card M as shown in FIG. After this, the user pulls out the memory card M from the slot, fills in the necessary items on a separately prepared special paper S, puts them in the envelope E, and mails them to the designated window of the authentication organization A. For example, the name, address, and telephone number are written on the sheet S.

  In the authentication organization A that has received the envelope E, the operator O sets the memory card M in the server S (computer) and decrypts the information in the code file F. Then, the operator O compares this with the information recorded on the pre-registered paper S, the information recorded on the server S, etc., and if they match, the procedure for notifying or reissuing the password to the user (Notification by mail etc.)

  The user who has received the notification inputs the password using the operation input unit 8 (step 209). Then, the authentication unit 48 determines whether the pre-registered personal identification number matches the input personal identification number (step 210). In this case, since the correct password has been input, the permission unit 49 permits the use of the function of the navigation device N (step 211).

[By unauthorized person]
First, as shown in FIG. 3 (B), when the navigation device is removed from the conventional vehicle C1 and a criminal who steals the navigation device is attached to the own vehicle C3, the power detection unit 45 reconnects the power supply. Is detected (step 201). Then, since the input request display instruction unit 46 instructs display of the input request screen, the input request screen is displayed on the display 6 as shown in FIG. 4 (step 202).

  On the other hand, the criminal cannot input the correct password, but looks at the displayed code issuance button. The criminal finds the meaning of the code issuance button by referring to a manual or the like that has been stolen with the navigation device or obtained separately, inserts the memory card M into the slot, and prepares the paper S.

  When the code issuance button is selected in order to obtain a personal identification number, the input determination unit 47 determines that there has been a code issuance instruction (step 204). In response to this, the code file generation unit 50 acquires the vehicle position information at that time (step 205), and generates an encrypted code file F together with a pre-registered personal identification number and authentication information (step 206).

  Then, since the memory card is inserted in the slot in advance (step 207), the code file output unit 51 outputs the code file F to the memory card control unit 9 (step 208). As a result, the code file F is recorded in the memory card M as shown in FIG.

  Thereafter, the criminal removes the memory card M from the slot, fills in the necessary items on the dedicated paper S, puts them in the envelope E, and mails them to the designated office of the certification organization A. For example, the name S, address, and telephone number fields are provided on the form S. These items can be known by the criminal from the obtained user's driver's license, vehicle inspection, etc. . However, it is also possible to enter incorrect information.

  Next, in the authentication organization A that has received the envelope E, the operator O sets the memory card M in the server S and decrypts the information in the code file F. Then, the operator O compares this with the information recorded on the pre-registered paper, the information recorded on the server S, etc., but because it is a criminal, it may not match or the handwriting of the paper may be different. . Therefore, the authentication organization A determines that the theft has occurred and does not perform a password notification or reissue procedure. Further, the own vehicle position information obtained by the decryption is managed by the authentication organization A. For example, it is possible to notify the police or the like or notify the user.

[effect]
According to the present embodiment as described above, in the case of a user who has replaced the navigation device N but has forgotten the personal identification number, if the regular procedure as described above is taken, the personal identification number will be known again. Can be used.

  On the other hand, even if the criminal who stole the navigation device N takes the above procedure, it cannot receive authentication and cannot know the personal identification number. At this time, the authentication organization A can grasp the approximate position of the product by looking at the vehicle position information, so that a clue for identifying the criminal is obtained.

  In this way, the navigation device equipped with the present invention can not be known even if it is stolen and cannot be used in the end, and if the procedure for obtaining the personal identification number is taken, the location information is known. If N recognizes that it is useless even if it is stolen, the effect of deterring theft can be obtained and it can contribute to the reduction of vandalism.

[Other Embodiments]
The present invention is not limited to the embodiment as described above. For example, the identification information registered in advance may be any information such as, for example, a nickname, a name of a relative, a favorite movie, a favorite book, or a frequently visited place. Such identification information may be included in the description content of the sheet.

  The code file may include a model number for identifying the device, etc., so that the model can be specified easily. Confidentialization of the code file includes all processes for concealing the contents. Accordingly, not only the encryption but also the prohibition of opening the file unless the preset authentication information (password) is input.

  Further, the code file may be sent to a server of the authentication organization A or the like via a communication line instead of being mailed to be authenticated. In this case, in said embodiment, it can transmit via the communication apparatus 10 (When it is built in the navigation apparatus N, or when the connection is maintained).

  The medium for recording the code file may be any medium as long as it can be sent. Therefore, the storage medium is not limited to a memory card that is a card-type storage device using a flash memory, and may be a USB memory, a small hard disk, an optical disk, a flexible disk, or the like. The position information may indicate a position where the current product exists, or may indicate a position that existed in the past. For example, various possibilities are conceivable depending on the setting and timing of recording, such as the position where the product is removed and the position where it is attached, but if some position information is obtained, it can be a clue. In the case of a large-capacity recording medium, more effective clues can be obtained by including travel history and a set route (whether actually traveled or not yet traveled) as position information. It becomes possible.

  Further, the recording medium on which the code file is recorded may be inserted into a personal computer or the like, and the code file may be transmitted using a communication environment such as a communication device connected to the personal computer. At this time, a form for inputting the items described on the above paper may be prepared on the website of the authentication organization A, and the items described may be transmitted from this site. Thereby, authentication can be automated on the server S side of the authentication organization A. However, since it is difficult to authenticate handwriting using handwritten paper, it is necessary to increase the types of authentication information to improve security. Furthermore, an image input of handwritten paper can be sent as an email attachment and authenticated.

  The functions that are permitted or not permitted by the permission means are usually all functions of the device. For example, only navigation functions, only video playback functions such as DVD and TV, only audio output functions, etc. It may be a part of the function of the device, and the user may be able to set that authentication is required for a desired function.

  In addition, the present invention is not limited to in-vehicle use but can be applied to other moving means and portable navigation devices. Furthermore, a device to which the present invention is applied is not limited to a navigation device, and can be widely applied to electronic devices installed in a moving body.
