Here, the pay information (contents) received via the wireless device 101 owned by the purchaser (user) is:
The data is stored (stored) in the hard disk 111 of the data box 102.

On the infrastructure side, the antenna (antenna of the terminal on the infrastructure side) 200 shown in FIG. 1 is arranged in the premises of the store so that it can communicate with the wireless device 101 mounted on the parked car. . In other words, for the client terminal side, it is possible to use the wireless device 101 mounted on the car to perform wireless communication with the antenna 200 disposed on the premises of the store in the infrastructure-side terminal device while parked on the premises of the store. it can. The antenna 200 is connected to a provider (content server) 300 via a communication line and the Internet. As described above, pay information can be distributed from a content provider to a purchaser by data communication.

The stores here are assumed to be convenience stores, gas stations, card dealers and the like. A provider (content server) 300 manages a host computer 301 and a database 302. The pay information (content) is stored in the database 302.
Is stored. The provider 300 controls the mechanism of information distribution to a moving car.

In the system configuration diagram of FIG. 2, the wireless device 101 of the vehicle-mounted device is connected to a provider (content server) 300 via a telephone network 201, a gateway 202, and the Internet 203. A settlement institution such as a bank, a credit company, or a post office contracts with and connects to the provider (content server) 300. That is, a bank, a credit company, a post office, a convenience store, and the like are used to transfer a fee to a purchaser (consumer).

Using the card reader / writer 104 shown in FIG. 2, information for confirming the user to reduce the fee can be input. Specifically, payment can be made by inserting an IC card 105 as a credit card. Note that instead of the card reader / writer 104, qualification information such as a personal identification number and a membership number may be input using a numeric keypad or the like. This input information is sent from the wireless device 101 to the provider 300, and is collated and authenticated (if it is determined whether or not the user is a user who can be delivered and confirmed), information is delivered. Become.

The provider (content server) 3 in FIG.

As pay information (contents), for example,
Examples include music data, paid hotel reservation information, paid ticket reservation information, image data, event information, advertising for members, movie data, English teaching materials, karaoke practice songs, and the like. This paid information (content) is
From 00, distribution is performed to a specific contractor, a purchaser (consumer) who can make a payment, and the like.

Next, the operation of the vehicle information processing system will be described. The card reader / writer 10 in the vehicle-mounted device 100
4, the information of the IC card 105 is read from the state where both IC cards 105 and 106 are inserted, and the settlement information and the personal information (the ID for the vehicle-side wireless device, the ID for the audio player, the ID for the storage medium, Related information)
Is sent to the provider 300 via the infrastructure-side wireless device. The provider 300 authenticates by collation (collation of a password or collation of a device ID). Thereby, the legitimacy of the vehicle side (user) is confirmed. Then, when a normal collation result is obtained, a distribution menu is sent from the provider 300 to the reader / writer 104 of the user via the infrastructure-side wireless device and the vehicle-side wireless device. The distribution menu is displayed on the display, and desired information is selected from the menu by the purchaser. The menu selection information is sent to the provider 300 via the vehicle-side wireless device and the infrastructure-side wireless device. In response, the provider 300 sends out the requested pay information, and in some cases, decryption key information and device activation information (identification information). At this time, it is desirable that all information be sent in an encrypted state in order to improve security.

Then, the pay information from the provider 300 is sent to the data box 102 via the infrastructure-side wireless device and the vehicle-side wireless device, and the pay information is stored in the hard disk 111 (digital information is stored). In the provision of this electronic information, the arrangement between the supplier and the receiver usually adds that the receiver guarantees the payment for this supply to the supplier and possibly specifies the equipment for reproduction. You can also. On the other hand, the decryption key is stored in the IC card 105 and the device activation information (identification information) is stored in the IC card 106.

Thereafter, an approval indicating that the reception of the information distribution is completed is performed, and the approval (famous) is transmitted from the reader / writer 104 to the provider 300 via the vehicle-side wireless device and the infrastructure-side wireless device. Can be After receiving the information distribution in this manner, the IC card 10
5 and 106 are carried by a user (driver or the like), and are brought into the vehicle only during use (during driving or the like).

Here, a method of payment when purchasing paid information will be described. There are two methods: a method of performing fee settlement when distributing information, and a method of performing fee settlement when distributing a key for decrypting encrypted information (or performing sales other than distribution). In this case, the encrypted information (content) may be free, but at least the decryption key information is preferably charged. In other words, when both the encrypted information (content) and the decryption key information are purchased at a store outside the vehicle, the payment is made by the same payment as when purchasing a normal article, but via a wireless device in the vehicle. In the case of making a settlement, settlement is performed in the following procedure.

Procedure 1). Before the content or the decryption key information is transmitted by the distribution side, an IC card that communicates with a card reader / writer disposed in the vehicle is authenticated to confirm that the IC card is valid for settlement.

Procedure 2). After confirming that the IC card is valid, distribution and settlement processing is performed. At this time, steps 1 and 2 may be reversed. Procedure 3). When the decryption key information is stored in an IC card, the IC card is confirmed to be valid in step 2), or at the same time, stored in another IC card via a card reader / writer arranged in the vehicle. . In other words, in the case of distributing the decryption key information, the decryption key information is basically stored in the IC card confirmed as valid in the procedure 2, and the decryption key information is transferred to another IC card using a card reader / writer. It is also possible to memorize.

Procedure 4). In some cases, when authentication of the owner of the IC card is required, personal authentication may be performed using the in-vehicle authentication mechanism. Returning to the explanation of the operation, when listening to music after receiving the distribution of the content as described above, the following is performed.

First, the IC cards 105 and 106 are inserted into the reader / writer 104, and the decryption key of the IC card 105 and the device activation information (identification information) of the IC card 106 are read. This device activation information (identification information) is sent to the data box 102. And the data box 10
In step 2, an authentication process is performed by inputting device activation information (identification information), and when the validity is confirmed, the operation (activation) of the audio player 103 is permitted.

Subsequently, in the processing circuit 113, the pay information of the hard disk 111, that is, the encrypted information (content) is decrypted with the decryption key of the IC card 105. This decrypted information is stored in the audio player 1
03, reproduced and output as sound from the speaker. In addition, the compressed encryption information (content)
Is decompressed and played.

As described above, this embodiment has the following features. (A) In-vehicle information including a hard disk (storage medium) 111 storing encrypted information, a processing circuit (processing device) 113 for processing the information stored in the hard disk 111, and an audio player (processing device) 103 In the processing system, information for decryption is stored in an IC card (portable information storage unit) 105,
The information of the card 105 is read by a card reader / writer (information reading means) 104, and the information
11 information is decrypted. (B) Hard disk (storage medium) storing information 11
1, an in-vehicle information processing system including a processing circuit (processing device) 113 for processing information stored in the hard disk 111 and an audio player (processing device) 103 for playing back the audio data by performing authentication processing by inputting identification information. The player (processing device) 103 is allowed to operate. Specifically, the identification information is stored in the IC card (portable information storage means) 106, and the IC card 1
06 card reader / writer (information reading means)
At 104, the identification information is input by reading.

According to (a) and (b), the IC card 1
Only persons having portable information storage means such as 05 and 106 (persons who can input identification information in a broad sense) can process information (reproduce electronic information). In other words, unless the portable information storage means such as the IC cards 105 and 106 are stolen at the same time as the hard disk 111, the processing circuit 113, the audio player 103 or the car itself, the information cannot be decoded or the audio cannot be decoded. No permission to operate the player 103 is given.
As a result, information can be reliably protected.

That is, even in the environment of a car, as electronic information becomes more advanced, the value of information newly delivered to the car or the added value of on-vehicle equipment for storing and reproducing the information increases.
On the other hand, the use of IC cards as an integrated management system including protection of the copyright of the distributed information, measures against theft of electronic information and in-vehicle devices that remain in the car, and settlement within the car, When leaving the vehicle, even if everything that stays inside the vehicle is stolen by taking both the IC card out of the vehicle, the electronic information itself cannot be effectively used, and therefore has no value. In addition, by disseminating this system to the public, a deterrent effect is produced against theft of in-vehicle devices and electronic information (contents) from the inside of the vehicle, whose value will increase dramatically in the future.

If the system configuration requires a password for validating the IC card, the information can be protected even if the IC card is stolen. In the case of FIG. 1, the ID number and the decryption key information of the IC card 105 and the device activation information (identification information) of the IC card 106 are used.
Since the three types of information are used, paid information (content) can be more reliably protected.

As a method of confirming the validity of the settlement, an IC by a card reader / writer using a wireless device is used.
The method of authenticating a card can be used to perform a number of payments besides payment by distribution. For example, at a gas station, when using an IC card to pay for gasoline, without handing the card to store employees,
Payment can be made without fear of copying card information. Also, at this time, if a device capable of performing voice recognition, voiceprint recognition, and numeric keypad input is arranged in the vehicle, the input of a personal identification number or the like for personal authentication is performed outside the vehicle because the device is inside the vehicle. There is an advantage that there is little chance of being seen or heard by others and that the information can be input without worrying about the surroundings, and that the risk of intercepting personal information such as a personal identification number can be reduced.

Further, since the payment is made in the vehicle, the reception route and the time zone of the electronic information distributed from outside to the vehicle by radio or the like are set to be the same, so that the simultaneous reception of the service and the payment can be improved. In addition, both the distributing side and the receiving side can reduce anxiety about liquidation.

Although both (a) and (b) described above are incorporated in the system, only (a) or only (b) may be incorporated in the system. When only (b) is incorporated into the system, the encrypted pay information (content) is read out of the key information of the IC card by a card reader / writer arranged in the vehicle, and the pay information is decrypted using the key information. In addition, a playback operation is performed on a playback device that has already been activated, but in addition, only decryption can be performed using key information of an IC card, and another playback start switch can be operated. A playback operation may be performed by a playback device. When only (b) is incorporated into the system, decryption of the encrypted information (content) may be permitted instead of permitting the operation of the audio player 103 (authentication by input of identification information). In the process, decryption of the encrypted information is permitted).

The card reader / writer 104 of FIG. 1 may be integrated with any one of the wireless device 101, the data box 102, and the audio player 103 (for example, the card reader / writer 104 and the audio player 103 are integrated). Also, the card reader / writer 104
, The wireless device 101, the data box 102, and the audio player 103 may all be integrated. Alternatively, the data box 102 and the audio player 10
3 may be integrated. Also, the IC card 105, 1
An IC chip may be used in place of 06.

As described above, the storage medium 111 and the processing device 1
02 and 103 and the information reading means 104 are integrated, or the storage medium 111, the processing devices 102 and 103,
The information reading means 104 and the in-vehicle communication device 101 for receiving information distribution may be integrated. Alternatively, the storage medium 111, the processing devices 102 and 103, and the information reading means 104 can be configured such that a separate one of them can communicate with an integrated one, or the storage medium 111, the processing The devices 102 and 103, the information reading means 104, and the in-vehicle communication device 101 for receiving information distribution are configured such that a separate one of them can communicate with an integrated one. You may. Further, the storage medium 111, the processing devices 102 and 103, and the in-vehicle communication device 101 for receiving information distribution are integrated, or the storage medium 111 and the processing devices 102 and 103 are integrated.
3, the information reading means 104, and the in-vehicle communication device 101 for receiving information distribution may be integrated. Alternatively, the storage medium 111 and the processing devices 102 and 1
03 and the in-vehicle communication device 10 for receiving information distribution
1 means that the separate one of them can communicate with the integrated one or the storage medium 111
, Processing devices 102 and 103 and information reading means 104
And the in-vehicle communication device 101 for receiving information distribution, the separated one of them can be communicated with the integrated one, or the information reading means 104 is separated. Information reading means 104 outside the vehicle.
The use of the information read out in the above or the use of the information outside the vehicle means that the information reading means 104 uses the information for decryption, the identification information, and the encryption for receiving the distribution. Information and either information for settlement or qualification confirmation, and use this information to decrypt information in equipment outside the vehicle, permit operation of processing equipment, and distribute it. You may.

Further, services other than distribution may be received by using information for settlement or qualification confirmation. Hereinafter, application examples and modifications of the embodiment described above will be described.
