SUMMARY OF THE INVENTION According to the present invention, in order to enable a content selling price to be changed according to a user's content purchase location, a content sales server sends an electronic value to a content purchase client via a network. In the content sales system that sells content, the content sales server knows the location of the content purchase client at the time of content purchase, and determines the sale price of the content according to the determined location. Regarding the location of the content purchase user at the time of content purchase, either one of the automatic method and the manual method based on the declaration of the user, or both of them can be combined.

[0006] In the manual method based on a user's declaration, the content sales server determines the location at the time of content purchase by the content purchase client based on the location ID of the content purchase location sent from the content purchase client user via the network. To know. Then, the price determining means refers to the price information storage means which holds the selling price for each location ID of the content, and determines the selling price according to the location at the time of the content purchase by the content purchasing user.

In the manual method based on the declaration of the user, a place ID display means for displaying the place ID of the place to the user at the place is provided for each place of the content sale, thereby facilitating the declaration of the place by the user. . The place ID display means may be a means for fixedly displaying the place ID, such as a poster or a signboard. However, if the location ID of the content sales location is fixed, some users may fake the content purchase location, and in order to prevent this, the location ID display means electrically displays the location ID. A place constituted by a display device or the like and periodically changing the place ID in the price information storage means by a place ID changing means provided in the content sales server, and displaying the place by the place ID display means in accordance with the change. It is desirable to change the ID. In this way, remembering the location ID of the cheaper selling location will not be useful,
Unauthorized acts can be prevented. Further, after notifying the content purchase client at the time of inquiring the content sale price from the user, the purchase request specifying the determined sale price and the location ID is transmitted from the content purchase client. Place I requesting purchase
If the selling price according to D is determined again, and if the selling price is different from the selling price in the purchase request, the purchase is not performed,
It is possible to prevent a fraudulent act such as inquiring the price of the content at a low-priced sales location and leaving the location later and actually purchasing the content.

On the other hand, in the automation system, a content purchase client used by a user is provided with location detection means such as GPS, and location information detected by the location detection means is periodically collected by a content sales server via a network. By updating the location information storage unit that holds the location ID and the user list for each content location, the location at the time of content purchase by the content purchase client can be known. In this case, by referring to the location information storage unit and the price information storage unit that holds the sale price for each location ID of the content, the sales price according to the location at the time of the content purchase of the content purchase client is determined. be able to. After notifying the determined purchase price to the content purchase client at the time of inquiring the content sales price, when a purchase request specifying the determined sales price is sent from the content purchase client, the location information storage means at that time and The selling price according to the contents of the price information storage means is determined again, and if the selling price is different from the selling price in the purchase request, the purchase is not performed. It is possible to prevent illegal acts such as inquiring and leaving the place later and actually purchasing it.

[0009] In both the manual method and the automatic method, when notifying the determined purchase price to the content purchase client, information of a content sales place where the content can be purchased at a lower sale price than the sell price is also notified. good. This makes it convenient for the user and can actively guide the user to a low-price sales location.

[First Embodiment] FIG. 1 is a block diagram showing a first embodiment of a content sales system according to the present invention. This system includes a content sales server 1 and a content purchase client 2. Content sales server 1
Is a service providing means 10 for providing a sales service,
Price determining means 20 for determining the price of the content, charging means 30 for charging based on the determined price, location information collecting means 40 for collecting location information of the user, location DB 70 for storing location information of the user, , A price DB 80 for storing content prices, and a content DB 90 for storing content information. Note that such a content sales server 1 can be realized by a computer such as a workstation and a program for a content sales system. The program for the content sales system is provided by being recorded on a machine-readable recording medium M1 such as a CD-ROM, a semiconductor memory, and a magnetic disk, and is read by the computer at the time of starting the computer and controls the operation of the computer. In this way, the above-described components constituting the content sales server 1 are realized on a computer.

On the other hand, the content purchase client 2
It comprises a terminal 50 that can be connected to the Internet or a public network, such as a computer or a mobile phone, and a location detecting means 60 that detects the position of the terminal 50 using means such as GPS. The terminal 50 is generally portable, and is connected to the Internet or the like by wireless communication.

FIG. 2 shows the relationship between the content sales server 1 and the content purchase client 2. The content sales server 1 and the content purchase client 2 are connected to a network 3 including at least one of a public network, a packet network, and the Internet, and can communicate with each other. In FIG. 2, only one client is described as the content purchasing client 2, but a plurality of clients may be present instead of one client. The same applies to the content sales server 1.

FIG. 3 shows an example of the content of the content DB 90. The content DB 90 is a database that holds a plurality of content attributes. Each record (row) of the database is one content, and a content ID that uniquely identifies the content, a content name, a description of the content, and an actual data name It is composed of The actual data name corresponds to the name of a content file that stores the content of the content. In the present embodiment, the content file itself is recorded on a recording medium different from the content DB 90, but may be recorded in the content DB 90.

FIG. 4 shows an example of the contents of the price DB 80.
The price DB 80 is a database that stores the price of each content sales location. One record (row) includes a content ID, a location ID of a location where the content is sold,
Consists of sales prices. For example, the line indicated by 402 is
The content identified by the content ID “1001” is “300” in the location specified by the location ID “9999”.
"Yen". Row 401, 403
As shown in FIG. 7, even if the content is the same as the row 402, the selling price may be different if the location ID is different.

FIG. 5 shows an example of the contents of the location DB 70.
The place DB 70 is a database that holds a list of users existing in places registered in advance, and includes a place name and a place I specific to a place where it can be specified that the place exists.
D and a list of user IDs existing at that location. For example, in the row indicated by 501, the user IDs “111111” and “2222”
The user identified by “22” exists, and the place ID that can specify “in pachinko 7” is “9999”.

The location detecting means 60 of the content purchasing client 2 shown in FIG. 1 transmits the name of the location where the terminal 50 is present as location information 61 to the location information collecting means 40 at a constant period. For example, when the GPS is used as the location detection means 60, the location where the terminal 50 exists can be recognized by latitude and longitude, and the latitude and longitude can be recognized by using a map information database (not shown) built in the location detection means 60. To get the current place name. The latitude and longitude may be transmitted as the location information, and converted into the location name by the location information collecting means 40. GPS
As a configuration other than the above, a configuration is adopted in which, for each sales point of each content, a wireless device that constantly transmits a place name by radio or infrared is installed, and the transmitted signal is received by the place detection means 60 to obtain the place name. Can be adopted.

The term "location" refers to a so-called physical location, but it is not always necessary to stick to this location. For example, a location in a network (WWW)
Page, provider, etc.). In addition, there is no problem even if a physical place and a network place are mixed. At this time, the location detecting means 60 detects the IP address of the content purchasing client 2 on the Internet and transmits the IP address to the location information collecting means 40. Further, the IP address can be used as the location ID. However, since one IP address is an ID assigned to one terminal, in order to recognize a provider by an IP address, the IP address is converted into a network address and used. The recognition of the provider by the IP address is not described here since it is not directly related to the present invention. In the following description, a place is described as a physical place.

FIG. 6 shows an example of the location information 61. The location information 61 includes a user ID and a location name. The example illustrated in FIG. 6 indicates that the user identified by the user ID “333333” is located in “7 pachinko parlors”.

First, the operation when the user selects the menu item "purchase" on the detail screen of FIG. 19 will be described.

When the user selects the menu item “Purchase” on the detail screen displayed on the terminal 50,
Sends a service providing request 51 including a purchase request without specifying a location ID to the service providing means 10 via a network. The service providing request 51 including the purchase request without specifying the place ID is the same as the service providing request in FIG. 13 in the first embodiment, and indicates that the purchase is requested in the first line, and the content is in the second line. I
D, the user ID is set on the third line, and the price (500 yen in the case of FIG. 19) is set on the fourth line.

When the service providing unit 10 receives the service providing request 51 including the purchase request without specifying the location ID (S1516Y), it sends the service providing request 12 having the same content as the service providing request 51 to the price determining unit 23. The price determining means 23 performs S150
7, the selling price of the content is calculated again in the same manner as described in S1508 and S1510, and compared with the price included in the service providing request 12 (S15).
17). In the normal case, the same price is calculated again and matches the price in the service providing request 12, but does not match if the selling price in the service providing request 51 has been falsified for some reason.

If the sales price calculated again matches the price included in the service providing request 12 (S15)
17Y), the accounting information 21 composed of the sales price and the user ID extracted from the service providing request 12 is sent to the accounting means 30, and the user who purchased the content is charged (S1518). In the billing means 30, the user ID
If the user specified in the above is charged only for the selling price, the charging method does not matter here. If the charging is successful, the price determining means 23 transmits the charging result 22 to the service providing means 10. The accounting result 22 is composed of whether or not the accounting is successful and the content ID. Upon receiving the charging result 22, the service providing unit 10 confirms the charging success, reads the content file having the file name described in the data name item of the content DB 90, and
(S1519). The terminal 50 receiving the content 11 displays the content. This completes the processing for selling the content.

On the other hand, if the re-calculated sales price does not match the price included in the service provision request 12 (S1517N), the process proceeds to step S1507, where the service provision request 51 for requesting a detailed screen without specifying a place ID is generated. The same processing as when receiving is performed.

Next, the operation when the user selects the "place ID input" menu item on the detail screen of FIG. 19 will be described.

When the user selects the menu item “Purchase” on the detail screen displayed on the terminal 50,
Issues a service provision request 51 including a place ID input screen request via the network after saving the detail screen of FIG. 19 internally.

FIG. 20 shows an example of the contents of a service provision request 51 including a place ID input screen request. The first line indicates a request for a place ID input screen, and the second line specifies a user ID.

When the service providing means 10 receives the service providing request 51 including the location ID input request from the terminal 50 (S1513Y), the service providing means 10 creates a location ID input screen (S1514) and displays the created screen. It is sent to the terminal 50 via the network (S151
5).

FIG. 21 shows an example of a place ID input screen created by the service providing means 10. It consists of a description to the user, a part for inputting the place ID, and a menu.

When the user selects “input” of the menu item on the place ID input screen displayed on the terminal 50,
The terminal 50 stores the input location ID and the stored FIG.
A service providing request 51 for requesting a detailed screen designating a place ID is created using the detailed screen 9 and transmitted to the service providing means 10 via the network.

FIG. 22 shows an example of a service provision request 51 including a detailed screen request specifying a place ID. FIG.
Is a format in which a location ID is added to the service provision request 51 shown in FIG. In this case, the place ID is "999
9 "is set.

If the service provision request 51 from the terminal 50 requests a detailed screen (S1506Y), the service provision means 10
The service providing request 12 having the same contents as described above is sent to the price determining means 23. The price determining means 23 includes a price DB 8
1 is read (S1507), and it is confirmed whether or not the location ID is stored in the service providing request 12 (S1508). In this case, since the place ID is stored (S1508Y), the selling price is determined as follows, and the determined selling price 22 is stored in the service providing unit 1.
0 (S1509).

First, the price determining means 23 acquires the content ID and the location ID from the service provision request 12. Next, a row in the price DB 81 that matches the acquired content ID and location ID is searched, and if the searched row exists, the price of that row is determined as the selling price. If the line you are looking for does not exist, the content IDs match,
Further, the price of the line in which the location ID is described as “0000” is set as the selling price. Therefore, when the user inputs an ID that exists as a location ID, the price is determined according to the location, and when the user inputs an ID that does not exist as the location ID appropriately, the normal price is determined.

Service providing means 1 receiving the selling price
0 creates a detailed screen by the same method as described above (S1511) and sends it to the terminal 50 via the network (S1512). The detail screen is created by the same method using the same data as in S809 in FIG. Therefore, for example, when the user designates a place ID corresponding to 7 pachinko parlors as the place ID, in the detailed screen of FIG.
"Your price 500 yen"
The detailed screen replaced with "300 yen" will be presented to the user. When the user selects the menu item “Purchase” in the detailed screen, the terminal 50 issues a purchase request specifying the location ID used in the service provision request 51 including the detailed screen request specifying the immediately preceding location ID. Service providing request 51 including
To be sent via network.

FIG. 23 shows an example of a service provision request 51 including a purchase request specifying a place ID. Service provision request 51 including purchase request without specifying location ID
13 (FIG. 13), a place ID is added.

When the service providing unit 10 receives the service providing request 51 including the purchase request specifying the location ID (S1516Y), it sends the service providing request 12 having the same content as the service providing request 51 to the price determining unit 23. The price determining means 23 performs S1507,
The selling price of the content is calculated again in the same manner as described in S1508 and S1509, and compared with the price included in the service providing request 12 (S151).
7). In the normal case, the same price is calculated again and matches the price in the service providing request 12, but does not match if the selling price in the service providing request 51 has been falsified for some reason.

If the sales price calculated again matches the price included in the service provision request 12 (S15)
17Y), the accounting information 21 composed of the sales price and the user ID extracted from the service providing request 12 is sent to the accounting means 30, and the user who purchased the content is charged (S1518). In the billing means 30, the user ID
If the user specified in the above is charged only for the selling price, the charging method does not matter here. If the charging is successful, the price determining means 23 transmits the charging result 22 to the service providing means 10. The accounting result 22 is composed of whether or not the accounting is successful and the content ID. Upon receiving the charging result 22, the service providing unit 10 confirms the charging success, reads the content file having the file name described in the data name item of the content DB 90, and
(S1519). The terminal 50 receiving the content 11 displays the content. This completes the processing for selling the content.

On the other hand, if the recalculated sales price does not match the price included in the service provision request 12 (S1517N), the flow advances to step S1507, and the service provision request 51 for requesting a detailed screen without specifying a place ID is generated. The same processing as when receiving is performed.

Service provision request 5 from terminal 50
If 1 is other than the initial screen request, the detail screen request, the ID input screen request, and the purchase request (S1516N), the service providing unit 10 executes an error process (S1520) and ends the process.

Third Embodiment FIG. 24 is a block diagram of a content selling system according to a third embodiment of the present invention. This system includes a content sales server 6, a content purchase client 7, and a location ID display unit 110. The content sales server 6 is provided with the location ID changing means 100 in the content sales server 4 in the second embodiment.
The content purchase client 7
Is the same as the content purchase client 5 in the second embodiment. Unlike the place ID display means 120 in the second embodiment, the place ID display means 110 is a display means capable of dynamically changing the display content, and is installed at a place where the user can easily see the sales place of the contents. It consists of an electrical display panel and the like.

The content sales server 6 can be realized by a computer such as a workstation and a program for a content sales system. The content sales system program is a machine-readable recording medium M such as a CD-ROM, a semiconductor memory, and a magnetic disk.
3 is provided and read by the computer when the computer is started up, and by controlling the operation of the computer, the above-described elements constituting the content sales server 6 are realized on the computer.

FIG. 25 shows the relationship between the content sales server 6, the content purchase client 7, and the location ID display means 110. The content sales server 6 and the content purchase client 7 are connected to a network 3 including at least one of a public network, a packet network, and the Internet, and can communicate with each other. Also, the location ID display means 11
The location ID to be displayed can be transmitted to 0 via the network 3. In FIG. 25, only one client is described as the content purchase client 7, but a plurality of clients may be present instead of one client. The same applies to the content sales server 6 and the location ID display means 110.

The content sales system of the present embodiment differs from the content sales system of the second embodiment in the place ID changing means 100 and the place ID display means 110. Hereinafter, only the differences will be described in detail. explain.

The place ID changing means 100 operates at regular intervals to change the contents of the place IDs in the place DB 71 and the price DB 81, and to display the changed place ID in the place ID display means 110 set in each place. Send to The place ID display means 110 is a place ID change means 1
The location ID sent from 00 is displayed.

The operation of the place ID changing means 100 will be described with reference to the flowchart shown in FIG. Location ID changing means 100
Is started at regular intervals by a timer of the content sales server 6 where the means is present (for example, a computer timer when the server 6 is realized by a computer).
When activated, the first row of the location DB 71 is read (S2001), and the location ID for the location of the read row
Is randomly generated with a predetermined number of digits (S
2002). Further, the generated location ID 101 is sent to the corresponding location ID display means 110 (S2003). Next, the location ID of the row read in the location DB 71 is updated with the generated location ID, and at the same time, the location ID in the price DB 81 that is the same as the location ID of the row read in the location DB 71 is updated with the generated location ID (S2004). . For example, when the location DB 71 has the contents shown in FIG. 17 and the location ID of the first line is generated by a random method, the generated location ID is transmitted to the location ID display means 110 installed in the pachinko parlor 7. Then, the original location IDs of the location DB 71 and the price DB 81 are updated. Next, the next row of the location DB 70 is read (S2005), and if the next row is read successfully (S2006Y), the operation from S2002 is performed on the read row. If reading of the next line fails (S2006N), a series of processing ends.

It is to be noted that the place ID may be generated by a method such as using the final digit as a checksum, and random generation is not necessarily required.

The place ID display means 110 is connected to the place ID change means 100 via a public network, the Internet, or the like.
The location ID 101 is received from the location ID changing means 100, and the content is displayed so that a user who has visited the content selling place where the means 110 is installed can see the content.

FIG. 27 shows that the location ID display means 110
An example of a state where D is displayed is shown. FIG. 27 shows location I
The place ID of the place where the D display means 110 is installed is:
At present, it is "5893625485".

The operation of this embodiment is basically the same as that of the second embodiment, and the content sales server 6 operates as shown in the flowchart of FIG. However, unlike the second embodiment, the location I related to the content sales location
D is the place ID changing means 100 and the place ID display means 11
Since the content is periodically changed by 0, it is possible to prevent a person other than the user who is actually at the content selling place from falsely purchasing the content at the price at the content selling place. Hereinafter, the operation of the present embodiment will be described focusing on this point.

In the same manner as in the second embodiment, a user issues a service provision request 51 including a detailed screen request (price inquiry request) specifying a location ID as shown in FIG. It is assumed that the data has been transmitted to the server 6. In this case, the place ID is "99
99 "is set. In response to the service providing request 51, the service providing unit 10 determines a price in the same manner as in the second embodiment, and sends a detailed screen including the determined price to the content purchase client 7. At this time, assuming that the contents of the price DB 81 are as shown in FIG. 16, 300 yen is determined as the price of the content ID.

Then, the user leaves the place,
Later, at another location, as shown in FIG.
It is assumed that a service provision request 51 including a purchase request designating 9999 is transmitted to the content sales server 6.
In the meantime, it is assumed that the place ID is changed from 9999 to, for example, 2222 by the place ID changing unit 100, so that the place DB 71 and the price DB 81 are changed as shown in FIG. Then, the service providing unit 10 receives the service providing request 51 including the purchase request specifying the location ID, sends the same service providing request 12 to the price determining unit 23, and calculates the selling price of the content again by the price determining unit 23. Then, since there is no place ID corresponding to the place ID = 9999 in the service providing request 12, 500 yen is determined as the price of the place ID = 0000. Therefore, the sales price calculated again does not match the price (300 yen) included in the service provision request 12, and the process does not proceed to the purchase process.

In this embodiment, S20 shown in FIG.
03 to the place ID display means 11
0 for display, and thereafter, the location DB 71 and the price DB 81 are updated with the location ID generated in S2004, but the time lag from when the user inputs the location ID to the content purchase processing (for example, S1517 in FIG. 18). Therefore, two place IDs may be temporarily stored in the place DB 71 and the price DB 81. Alternatively, the location D is displayed in S2003 and then displayed in S2004.
A fixed time may be secured before updating B71 and price DB81.

As described above, according to the present invention, the content purchase price can be changed according to the location where the user purchases the content, and the content purchase location can be specified without special equipment. It is possible to prevent the content purchase place from being falsified when the content is purchased. In addition, the following additional effects can be obtained.

The point is that the place where the contents are sold can be advertised. The reason is that by changing the price of the content according to the place where the user purchases the content, the user who wants to purchase the content wants to purchase at a cheaper place, and consequently sells the content at a lower price. This is because users will be gathered at the same time. In addition, the loss caused by lowering the content price can be compensated for by collecting a fee from the content sales location as an advertising fee for the content sales location, and the content seller can secure the same sales as when selling at the normal price. Can be expected. Content sales location owners,
If the sales place is a store, an increase in sales can be expected due to the gathering of users. If the sales place is an event venue, activation of the event by the gathered users can be expected.

[0099] The object is to enable the system to be rapidly spread. The reason is that for each location a different location I
By setting D, it is possible to perform position detection without preparing a special position detection device, and a service can be provided by an Internet-compatible mobile phone that is currently widely used. Furthermore, since the location ID is changed at regular intervals, fraudulent purchases at the same price as the content sales location are prevented even when the content sales location is not present. It is also to keep the minimum.

[0100] It is an object of the present invention to rapidly spread electronic content sales. The reason for this is that physical distributors oppose the disruption of the current distribution of physical content, which is a factor that hinders the spread of electronic content. By selling in stores, not only customers visit physical stores, but also by kicking back a certain percentage of physical stores from electronic content sales in physical stores, sales are more than ever before, This is because the factor against which the physical distributor is opposed is eliminated.
