Can be. The antenna 200 is connected to a provider (content server) 300 via a communication line and the Internet. As described above, the system is capable of distributing pay information from a content provider to a purchaser by data communication.

A provider (content server) 300 manages a host computer 301 and a database 302. The database 302 stores pay information (contents). Here, the database 302 according to the present embodiment stores an electronic warranty card. By using this electronic warranty card, pay information is once distributed to the purchaser and then redistributed (from the information distribution history). Free re-distribution) is permitted. In other words, the system terminal includes means (redistribution request program and operation buttons) for requesting free redistribution.

In the system configuration diagram of FIG. 2, a communication device 101 of an on-vehicle 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).

FIG. 2 shows a card reader / writer 10 for payment.
Reference numeral 2 denotes a device for inputting information for confirming a user to deduct a fee. Specifically, settlement can be performed by inserting an IC card as a credit card. Note that, instead of the card reader / writer 102, a device having a numeric keypad for inputting a personal identification number and a member number may be used. This input information is transmitted to the communication device 10

That is, the electronic guarantee card can specify at least one of the expiration date of distribution and the number of times of distribution validity as a condition for permitting re-distribution.
The ID number of the storage medium 104 is assigned to each purchaser.

Although the in-vehicle device is used in FIG. 1 as a terminal device for distribution, other devices such as an Internet terminal, a vending machine type (kiosk type terminal), a mobile phone, a PHS, and other wireless communication devices are also used. be able to. The data communication system includes Internet, satellite communication, DSR
C, an optical beacon, a radio beacon, or the like, or a combination thereof. Furthermore, the data communication method may be wireless or wired. For example, the data communication method may be wired communication even in a vehicle-mounted device at a predetermined location such as a convenience store.

Referring to FIG. 3, a method of determining a guarantee number of the electronic guarantee will be described. From distribution information number (number related to paid information), distribution date, customer information (name etc.), password (password for payment), ID verification number, etc.
By encrypting using a key including the device ID number, a certificate number is created. There are no two guarantee numbers, and they are used as information unique to distribution. As described above, when the distribution of the first pay information is completed, the guarantee information number is created by encoding and encrypting the information unique to the distribution. At this time, the warranty number,
It can be created using at least the number relating to the pay information and the customer information, or can include at least the password number for toll payment.

In this embodiment, the pay information is guaranteed by an electronic warranty card. The details of the guarantee will be described more specifically with reference to the following examples (i) to (vi). Regarding the object of the guarantee, the object of the guarantee is limited to the storage medium 104 as (i). That is, the storage medium 104 (ID2) is collated at the time of assurance, and re-distribution is permitted if the storage medium 104 has been initially distributed. This is effective in making a guarantee when data corruption occurs in the storage medium 104.

Regarding the object of the guarantee, (ii)
The guarantee target is limited to the recording / reproducing device 103. That is, the recording / reproducing device 103 (ID1) is collated, and re-distribution is permitted for the recording / reproducing device 103 that has received the first distribution.
In this way, when the recording / reproducing device 103 with a built-in storage medium is used, or when the storage medium 104 and the recording / reproducing device 1 are used.
This is effective in a case where the data of “03” is merged by an authentication process or the like (when the operation is limited to one-to-one). Or,
According to a contract between a plurality of designated recording / playback devices 103,
This is also effective when a plurality of distributions from the terminal are permitted.

Regarding the object of the guarantee, (iii) the object of the guarantee is limited to the purchaser (consumer). That is,
The consumer (ID3) is collated, and re-distribution is permitted to the consumer who paid the fee. This is effective when the consumer has a plurality of recording / reproducing devices 103 and storage media 104. In addition, re-distribution when a new recording / reproducing device 103 or a storage medium 104 is purchased can be performed. Further, re-delivery on a friend's device (including a friend's car) is possible.

Regarding the object of the guarantee, (iv)
Eliminate restrictions such as (i) to (iii) and purchaser (ID
3) Recording / reproducing device 103 (ID1) and storage medium 104
(ID2) is checked for at least one of
If it can be confirmed that "the fee has been paid once", re-distribution is permitted. In other words, re-distribution is permitted only by collation with respect to items for which payment confirmation can be performed on the electronic guarantee card. This is effective when paying once in a family, a friend, a workplace, or the like, and distributing as many times as necessary.

On the other hand, regarding the guarantee conditions, (v)
Limit the period. Therefore, the database 30 of FIG.
As shown in 2, the first delivery date and the expiration date are confirmed.
As for the guarantee conditions, the number of times is limited as (vi). For this purpose, the number of distributions and the number of valid times (the maximum number of possible distributions) are confirmed as shown in the database 302 of FIG.

Alternatively, it is possible to guarantee by combining the above limitations (i) to (vi). For example, "The storage medium 104 and the consumer are limited, but the recording / reproducing device 103 is not limited, the validity period is one year, and re-distribution is allowed up to three times."
Set conditions such as. This means that the degree of freedom of setting by the provider is increased.

FIG. 4 shows the storage location of the electronic warranty card (guarantee card number). The electronic guarantee card includes a provider (content server) 300, a communication line company 210, a communication device (terminal) 101, a recording / reproducing device 103, and a storage medium 10.
4. It may be stored (stored) in at least one of the card reader / writer for toll settlement 102. At this time, a plurality of devices may store the electronic certificate. Then, when redistributing, this guarantee number is decrypted and collated.
In this case, by performing encryption processing using the key including the device ID code at the time of receiving the distribution first, it is possible to prevent unauthorized redistribution to a different device.

FIG. 5 shows a department that executes a process (authentication process) for confirming the validity of the redistribution. Authentication processing is performed by the provider (content server)
300, communication line company 210, communication equipment (terminal) 10
1, the recording / reproducing device 103 and / or the charge settlement card reader / writer 102 may be used. That is, since each device performs an authentication process, it is possible to improve security by confirming whether the terminal is a legitimate terminal. Note that the authentication process can be performed by all devices, but mutual authentication can be performed by performing the authentication process by at least two devices.

At this time, if the system requires a personal identification number to receive the redistribution, lending and borrowing of pay information can be prevented. That is, the password of the credit card, that is, the number for performing the charge settlement is used as the password of FIG. 3, and when receiving the redistribution, the input equivalent to the password is performed. In this way, since the password of the credit card is generally not disclosed to others, it is useful for fraud prevention. In other words, there are few people who tell their personal identification numbers, such as cash cards, even if they are friends. For example, it is because a family member cannot listen to a music CD that has been bought, and a family cannot buy the same DC several times.

The storage (storage) location of the electronic certificate of FIG.
The method of checking the validity will be specifically described with an example. As a case 1, the provider 300 stores the electronic guarantee card, and when there is a request for redistribution from the user, the data is collated to confirm the validity.

As Case 2, the communication device (terminal) 101
Manages the electronic guarantee card, and when the user requests redelivery, transfers the electronic guarantee card to the provider 300, or confirms the validity in the communication device (terminal) 101 and sends the result to the provider 300. Tell

As a case 3, the electronic guarantee card is stored in the IC card 102a, and the electronic guarantee card is stored in the provider 300 or the communication device (terminal) 10 when the user requests redelivery.
1 and confirms its validity here.

As Case 4, an electronic certificate is stored in the recording / reproducing device 103, and when the user requests redelivery, the electronic certificate is transferred to the provider 300 or the communication device (terminal) 10
1 and confirms its validity here.

As a case 5, the digital certificate is stored in the storage medium 104, and when the user requests re-distribution, the digital certificate is transferred to the provider 300 or the communication device (terminal) 10
1 or to the recording / reproducing device 103, where the validity is confirmed.

The device for confirming the legitimacy is provided with what is commonly called a security module (hardware or software), and may perform encryption processing, decryption processing, storage of its key, authentication processing, and the like. desirable. Further, in order to confirm the validity, the history may be used for collation by connecting to the organization (bank, credit company, post office, convenience store, etc.) used for the delivery of the fee.

Next, the flow of information in the information distribution system of the present embodiment will be described using an example. Figures 6 and 7

Then, the distribution menu is sent from the provider to the recording / reproducing device via the communication line company, the infrastructure-side communication device, and the vehicle-side communication device. The distribution menu is displayed, and when the purchaser selects re-distribution from the menu, the warranty card number is read. The redistribution request and the warranty number are sent to the provider via the vehicle communication device, the infrastructure communication device, and the communication line company. The electronic warranty is confirmed at the provider. Specifically, in addition to the verification of the guarantee number in the electronic warranty, it is confirmed whether or not conditions for permitting re-distribution (expiration date, valid number of times, etc.) are satisfied.

When the validity can be confirmed, the pay information is sent from the provider to the recording / reproducing device via the communication line company, the infrastructure-side communication device, and the vehicle-side communication device. Then, the pay information is stored in the recording / reproducing device. Thereafter, approval (famous) is sent from the recording / reproducing device to the provider via the vehicle-side communication device, the infrastructure-side communication device, and the communication line company, and the content of the electronic warranty is updated. Specifically, the database 3 of FIG.
02 is incremented by “1”.

As described above, when re-distribution is requested on the purchaser side, the guarantee number as distribution history information is sent to the content provider, and re-distribution is performed in response to this. For this purpose, the terminal stores the guarantee number sent in addition to the pay information when distributing it from the content provider to the purchaser, and stores the guarantee number when requesting re-delivery. (Re-distribution request program and operation button).

As described above, after the distribution of the pay information, an appropriate guarantee can be obtained, for example, if the user has unexpected data loss, the user can be re-distributed without paying any money. From the information distribution side, it is possible to freely set copyright (set guarantee contents). For details of the setting of the guarantee content, the above-mentioned guarantee object of (i) is limited to the storage medium 104, and the guarantee object of (ii) is the recording / reproducing apparatus 1
03, the limitation of (iii) is limited to the purchaser (consumer), the limitation of (iv) is eliminated, the period of (v) is limited, and the number of times of (vi) is limited You can do it freely.

That is, until now (conventionally), no guarantee has been given to the distributed data. For example,
If you buy a music compact disc (CD) at a store and open it at home, if the CD is broken or damaged, you must go to the store to exchange it. Similarly, in the present embodiment, in order for the user to receive the information distribution, the provider 30
0, communication terminal 101, IC card 102a, storage medium 1
04, record the information at the time of distribution to any of the recording / reproducing devices 103 as a history (electronic guarantee) by applying security (encryption, authentication) of counterfeit measures, etc. When the provider 300 determines that the electronic certificate is valid using the electronic guarantee, measures such as free re-delivery can be taken in accordance with the specified guarantee contents.

Also, by using the guarantee number shown in FIG. 3 to confirm that the information is not a valid reason or an illegal act (copyright problem), the information once distributed is redistributed free of charge. Is guaranteed.

It should be noted that the re-distribution may be performed at a low price, in addition to being performed free of charge (free of charge). Also, in the explanation so far, the case of delivering paid information has been described,
