The present invention relates to a content transmission system for a mobile terminal that performs charge collection of content without relying on credit card and communication charge addition.

Many portable terminals, such as a mobile telephone, download content from a server by the communication function, and display or execute the downloaded content. In addition, there are many contents available by downloading using the communication function of such a mobile terminal.

Among these contents, there are paid contents for which the usage fee is collected when downloading and using them, and free contents for which the usage fee is not collected. As a method of charging the fee for downloading paid contents, the user of the mobile terminal who is the subscriber of the communication service is used. There is a method of adding a content fee to the communication fee. In addition, as a method for charging a fee, a system for making payment using a credit card number entered by a user at the time of downloading, and paying the fee to the user who downloaded the advertisement by attaching an advertisement to the content to be downloaded instead. There is a system for viewing the advertisement. (See Patent Document 1, for example)

(Patent Document 1) Japanese Patent Laid-Open No. 2002-140250

However, the method of viewing an advertisement cannot directly recover the cost of using the content from the user. In addition, there is a limitation in the direct method of making a payment by allowing a user to enter a credit card number. That is, in the case where payment by credit card is executed, in order to facilitate the collection of payment fees, a minimum fee amount of the content is usually set as a payable condition. When the content is, for example, a game program, the fee for the content is used. If it is set at a small amount less than the minimum rate, payment by credit card cannot be used. In addition, in the case of using the method of claiming the content usage fee in addition to the communication fee, the downloaded content must be registered in a site operated by a communication service provider that executes the communication fee collection. However, when content is not registered on the site due to a condition such as a limitation of the number of registrations, collection of the usage fee becomes difficult. As a result, technically, the number of contents available by the portable terminal increases, but most of them cannot be used because the registration is not made on the communication provider's site.

In addition, even if the content is registered on a site operated by a telecommunications company, the downloading procedure includes the billing procedure without the presence of a dealer or the like in the procedure for downloading the content. It is operated by operating a button or the like. In this case, the portable terminal user feels anxiety about the operation at the time of downloading and uncertainty about the payment. For this reason, the use of content is very insignificant compared to the number of available mobile phones.

The present invention is to solve the problems of the prior art, and even if the content is not registered on the site operated by the communication service provider, it is possible to recover the content usage fee without using the credit card payment. It is an object of the user to provide a system for easily selecting content.

In order to achieve the above object, the present invention provides the following content transmission system.

(1) a mobile terminal for displaying extracted content transmitted from a server, a content server for transmitting one or more extracted contents pre-registered through the communication network to the mobile terminal, and an identification code corresponding to the one or more extracted contents to be transmitted. A content transmission system comprising a download card group including a plurality of download cards described therein, and an authentication server for authenticating an identification code transmitted from the mobile terminal via a communication network. The identification code is different from any identification code described in other download cards belonging to the download card group, and the authentication server is allowed to transmit the extracted content to the content server only once for one identification code sent from the portable terminal. Content transmission, characterized in that for executing System.

Here, the portable terminal is, for example, an information terminal such as the cellular phone 12 and the PDA shown in FIG. The content is, for example, portable terminal ringing tone and standby screen that can be used in a mobile phone, text, audio, image, moving image data used for information service, and digital data such as a program and a game that execute display control of the data. Contents in the present invention are stored in the content server 18 that accumulates a plurality of contents as shown in FIG. 1, for example. The extracted contents are contents which are selected to be extracted from one or more of these accumulated contents according to one identification code transmitted once from the portable terminal and transmitted from the content server to the portable terminal.

The download card is a card-type display medium, for example, a card 11 as shown in Fig. 3, for example, on which the name of the content, the method of use thereof, and the identification symbol 19 are printed. One or more pieces of content information and an identification code corresponding thereto are printed on one card, and a type of card also exists corresponding to the type of content that can be downloaded. In addition, since one card may include one or more pieces of content information and each content corresponds to one download, a plurality of cards exist for one type of content. The set of these cards constitutes a card group.

For example, when these content cards are displayed at a store, the user of the mobile phone 12 sees the contents of one or more contents described in the displayed cards, and purchases a card in which the favorite contents are described. The use price of the content is paid through the purchase of the card. Here, the card is given a right to use the content printed there, and the user obtains this right through the purchase of the card.

When the user inputs the code described in the purchased card 11 into the cellular phone 12 by button operation, the code is transmitted to the authentication server 16 via the communication network. The authentication server is an apparatus for authenticating whether or not the transmitted code is described in a card normally purchased, that is, the validity of the code as shown in FIG. When the authentication server 16 authenticates that the code transmitted from the mobile phone 12 is valid, the extracted content is transmitted from the content server 18 to the mobile phone 12.

Here, the identification code written on the card is different for each card even if it is for the same kind of game. And any one code transmitted from the mobile telephone 12 is authenticated as being valid only once. That is, even if a code once determined to be valid is later sent to the authentication server 16 again, the extracted content is not sent again twice. That is, the right to download each of the one or more contents corresponding to the identification code has the same effect as used all by one download.

In this way, by using the card given the right to download as a medium for content download, it is possible to purchase content that is surely paid for and delivered.

(2) The content transmission system according to (1), wherein the identification code described in the download card is in the form of a URL or other character string.

URL is an abbreviation of Uniform Resource Locators and is a notation method for uniquely designating a place for storing information such as a file disposed on a computer network. For example, by using the identification code 19 in URL format as shown in FIG. 3, a server and a directory are designated by a method of designating a web page (or a swap page) by a browser program or the like operated by the mobile terminal. Therefore, it is possible to access the server from the portable terminal and input the identification code without a special program for code entry.

Also, while using URLs is a common way to indicate where to store information, such as files, users of mobile phones can use the '*', '#', ' You can also access the server by pressing Call, Internet Connection, or a numeric key or combination of keys. In this case, instead of the identification code, the download card may describe how to use such a key or a combination thereof.

(3) The content transmission system according to (1), wherein the description of the identification code on the download card is made by a combination of keys (characters) included on the keypad of the cellular phone.

Since the identification code is described by a combination of keys (characters) included on the keypad of the cellular phone, the identification code can be simply inputted using the keypad of the portable terminal.

(4) The content transmission system according to (1), wherein the description of the identification code on the download card is in a representation format of a two-dimensional pattern.

The two-dimensional pattern is a code composed of, for example, a black and white two-dimensional shape as shown in FIG. When the two-dimensional pattern is used, authentication can be performed on the server after code conversion of the result photographed by the camera attached to the portable terminal. Thereby, there is an effect of reducing the time for the user of the portable terminal to perform the button operation to input the identification code and the possibility of incorrect input.

(5) The content transmission system according to any one of (1) to (4), wherein the extracted content is a game program.

Among the various types of contents, game contents that are the object of hobby are high in merchandise and are likely to be a target of trading, and thus are preferable for the system of the present invention that can purchase contents in the form of card purchase.

(6) The content transmission system according to any one of (1) to (5), wherein the download card has a column for describing personal information of the owner of the mobile terminal on the back side.                         

For example, as illustrated in FIG. 8, a column for describing personal information is provided on the back of the card so that the user can return the card describing the personal information to a store or the like. The retailer or the like can smoothly obtain the information of the specific content user, and can be utilized as a tool for customer management.

(7) A download card group composed of a plurality of download cards, wherein the download card belonging to the download card group corresponds to a name of one or more extracted contents and one or more extracted contents that can be transmitted to the mobile terminal. An identification code is described one by one, the identification code described in the download card is different from any identification code described in other download cards belonging to the download card group, and the identification code is transmitted from the mobile terminal via a communication network, A group of download cards comprising a download card with an identification code characterized in that, when transmitted to an authentication server for authenticating the identification code, one or more extracted contents corresponding to the identification code are transmitted from the content server to the mobile terminal.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 is a configuration diagram showing a configuration example of the first embodiment of a content transmission system according to the present invention. As shown in Fig. 3B, the card 11 is printed with the identification code 19 necessary for introducing and downloading the name and contents of the content. This identification code is input to the cellular phone 12 by the user's button operation, and is transmitted therefrom to the authentication server 16 via the telecommunications provider network 13 and the Internet 15. The authentication server 16 transmits the authentication result of the identification code to the content server 18, and the content server 18 transmits the content accumulated therein through the Internet 15 and the communication service provider network 13 to the mobile terminal 12. To send). Hereinafter, the embodiment shown in FIG. 1 will be described in detail.

When the user of the mobile terminal wants to download and play content such as a game, for example, on the mobile phone 12 he or she uses, a card 11 corresponding to the game is obtained. For example, a user purchases a card at a cell phone store and other stores (for example, a convenience store, a department store, a large discount store, etc.) and a convenience store, obtains it as a premium, or obtains it as a propaganda product. Here, when a user directly purchases a card at a retail store, the user becomes a sales model in which the user pays a fee for using the content directly.However, when a user purchases a card as a giveaway, a specific company may advertise its image or product. It is a sales model that distributes the card to users for free. That is, in the latter case, since a particular company asks the manufacturer of the card to manufacture the card and pays the manufacturer the cost of producing the card, that is, the content fee, this is a kind of business-to-business (B2B) business model. It can be seen as one.

There are many types of content that can be downloaded and used on a mobile phone, and cards exist for each kind of content. In addition, the content corresponding to one card may be one or more. For example, when two or more contents correspond to one card, these contents may constitute a package of various types of contents.

Here, the card 11 can print visual information on the surface thereof, and the material may be paper, plastic, metal, or the like, and may take various forms such as an IC card and a postcard. In this case, it is advantageous to display and sell in large quantities in front of the store, or to be carried and carried by the user even after purchase. The name and content of the content are printed on the card in order to help the user understand the content of the content and to make it easier to select a desired one from a plurality of contents. In addition, as shown in FIG. 3B, the content information 17 may be printed on the card, such as a content fee, a game method, and a button operation method. In addition to the information of these contents, the card 11 is printed with an identification code 19 in the form of a URL or other character string of the Internet input to the portable terminal in order to download the contents corresponding to the card.

In addition, the card 11 may be manufactured in the form of a scratch card. In this case, the card 11 is peeled off when the card 11 is scratched with a coin or the like on the printed portion of the identification code as shown in FIG. 3A. A lead-like opaque substance that can be deposited is applied, so that the identification code cannot be recognized externally by itself. And when the part to which this lead-like substance was apply | coated is peeled off with a coin etc., the identification code printed under it becomes recognizable from the outside.

By doing in this way, it is possible to prevent theft of content that may be caused by a person who does not legitimately obtain a card stealing an identification code at a store or the like. After the user obtains the card, the user can scrape off the lead-like material with a coin or the like and download the content using the identification code printed thereunder.

The identification code 19 printed on the card 11 corresponds to one or more contents posted on the card, and some or all of the contents of the identification code 19 differ for each corresponding content. For example, as shown in Fig. 2, there is a different part in the content of the identification code printed on the card 11a of the A content and the card 11d of the B content. As a result, the content transmission system can identify what kind of content a download request was made when the identification code was transmitted. In addition, even if the content is the same, some or all of the content differs for every card. For example, as shown in FIG. 2, each identification code printed on the card 11a of the A content and the card 11b has a portion of different contents. Thus, a unique identification code is printed on each card. By assignment of this unique identification code, the content transmission system can identify whether any identification code 19 is the identification code described in the card used in the past or the identification code entered for the first time. That is, even if the identification code 19 described in the used card is input again, the content corresponding to the identification code 19 is not downloaded, so that only once for each of the one or more contents corresponding to the identification code 19 is allowed. It is possible to download.

In the input of the identification code 19, the user of the mobile phone 12 sees the identification code 19 which is the letter and symbol printed on the card 11, and operates the button etc. of the mobile phone 12 with the letter or the like. To execute. In other words, the identification code 19 is input from a button or the like of the cellular phone 12. When the identification code 19 adopts the URL format indicating the location of the file on the Internet, the cellular phone 12 downloads, browses or executes the file placed on the web server indicated by the URL by input of the identification code. do. Otherwise, the mobile terminal enters the URL described in a separate place on the card, downloads the data of a web page placed on a particular web server, or sequentially selects a link from the web from a portal site for mobile phones. To download a web page placed on a particular web server. The web page displays instructions for entering the identification code written on the card. Thus, the portable terminal transmits the identification code input from the button or the like of the cellular phone 12 together with the telephone number or address information of the cellular phone 12 to the server.

Meanwhile, although one content corresponds to one identification code in the card illustrated in FIGS. 2 to 3 b, one or more contents may correspond to the card according to the present invention. In this case, the identification code corresponds to one or more contents corresponding to the card, and a function for allowing a user to select any one of these contents should be provided. Accordingly, the web page downloaded by the above-described URL or the like may provide a menu for selecting any one or more contents corresponding to one identification code.

In describing the first embodiment of the content transmission system according to the present invention, data to be downloaded using a URL or the like is described using a web page of a web server as an example. However, the present invention is not only a web page of a web server. This may also apply to downloading data from a swap page on a WAP server.

In addition, the input of the identification code 19, instead of entering the URL directly, '*', '#', 'call', 'internet connection' or a numeric key or a combination of keys included in the keypad of the cellular phone. It can also be done by pressing. In this case, the download card 11 may describe how to use such a key or a combination thereof instead of the identification code.

The identification code input to the cellular phone is transmitted to the authentication server 16 via the carrier network 13 and the Internet 15 as shown in FIG.

4 shows an example of the configuration of the authentication server 16 and the content server 18. Since the configurations of the authentication server 16 and the content server 18 are the same, both will be described with reference to FIG. 4. The authentication server 16 and the content server 18 include the CPU 20, the input device 21, the display device 22, the RAM 23, the HDD 24, the communication devices 25 and 26, the optical disk drive. (28) Each is constituted by being connected by the bus 29. The CPU 20 stores the server program stored in the HDD 24 or the optical disk drive 28 in the RAM 23, and executes a program execution process. A communication device 25 such as a modem and a router connects the server to the Internet 15, and the communication device 26 connects the server to another server. The HDD 24 or the optical disk drive 28 of the authentication server 16 stores a database of identification codes containing information on whether the identification code has been transmitted in the past. In the content server 18, the HDD 24 or the optical disk drive 28 stores contents that can be downloaded and executed on the mobile phone 12. FIG. These stored data are stored in the RAM 23 at the time of use, and conversely, the data updated by the server program is transferred from the RAM 23 to the HDD 24 or the optical disk drive 28 and accumulated.

In the example of configuration of FIG. 1, the authentication server 16 performs authentication regarding the validity of the transmitted identification code. This is because the mobile phone user who did not purchase the card enters an arbitrary identification code or re-enters the identification code described in the card which has been used in the past. To prevent undownloaded.

The identification code 19 is composed of letters, numbers or symbols, or a combination thereof, and may include a list of letters, numbers or symbols having no dictionary meaning. In addition, when an arbitrary identification code is input to the mobile terminal and transmitted therefrom, the identification code is necessary for specifying each card so that the probability of matching with the identification code described on the card not sometimes purchased is low. In addition to the information, redundant information is also included.

The processing of the authentication server 16 will be described with reference to FIG.

The processing of the authentication server 16 is performed by the CPU 20 controlling each component device in accordance with the server program recorded on the HDD 24 or the optical disk drive 28.

When the server program is executed, the CPU 20 of the authentication server 16 reads the identification code 19 received through the communication device 25 in step S101. In this way, the identification code input to the portable terminal and transmitted to the authentication server 16 via the telecommunication carrier network 13 and the Internet 15 is read. Next, the CPU 20 verifies whether the identification code 19 is valid by performing an operation using the identification code data itself or by comparing with the information of the valid identification code in the database of the code ( S102). If it is determined that the identification code is valid, the CPU 20 searches the database of the identification code stored in the HDD 24 (Sl03) and checks whether the identification code has already been used in the past. In this step, when the identification code is already used (S102: No) and when the identification code itself is not valid (S104: No), the CPU 20 controls the communication device 25 through the control. The mobile phone 12 displays "unable to access" with the reason (S107). On the other hand, when the identification code is valid and not used in the past, the CPU 20 transmits one or more contents corresponding to the identification code to the content server 18 under the control of the communication device 26. A signal for requesting information and information for specifying a phone number or address of the cellular phone 12 to which the identification code is input are transmitted (S105). In this way, the authentication server 16 requests the content server 18 to transmit the content.

The content server 18 accumulates a large number of contents that can be downloaded and used by the mobile telephone 12, and the content server 18 is connected to the authentication server 16 by a dedicated line or the like. When the content server 18 receives a signal requesting the transmission of one or more contents from the authentication server 16, the mobile phone 12 transmits the corresponding contents among the accumulated contents through the Internet 15 and the communication service provider network 13. To send). That is, the content server 18 first transmits an e-mail to the cellular phone 12 based on information specifying the telephone number or address transmitted from the authentication server 16. The e-mail includes a URL indicating the place where the content is placed. Here, the URL indicating the placement place of the content transmitted to the mobile phone 12 by the content server 18 may be transmitted in the form of a short message service (SMS) as well as an electronic mail. Next, the mobile telephone 12 which has received the electronic mail downloads the content data from the designated URL.

Here, the content server and the authentication server have different roles, and each of them is implemented as hardware. However, the content server and the authentication server may share hardware so that a server program executed in parallel with the above process may be executed. .

Fig. 6 is a diagram showing a card used in the content transmission system as the second embodiment of the present invention.

In the second embodiment of the content transmission system, for example, a CCD or CMOS camera can be built in or connected to the cellular phone 12. The card 6 is printed with an identification code by a two-dimensional code, that is, a two-dimensional identification code 32, rather than an identification code by a letter symbol or the like. The two-dimensional identification code represents information in a two-dimensional plane of black and white so that a large amount of data can be represented as compared with a bar code. FIG. 6 shows an example of a so-called matrix type two-dimensional identification code in which black and white scales are combined. Although shown, the identification code by other methods, such as multi-stage, may be used.

In the second embodiment of the content transmission system, the mobile terminal user who has obtained the card 30 first downloads data of a web page arranged on a specific web server dedicated to content download, or from a portal site for a mobile phone. Selects a web link in order to download data of a web page placed on a specific web server dedicated to content download. On this web page, an instruction is displayed to the cellular phone user to photograph the two-dimensional identification code 32 printed on the card 30 with the cellular phone 12 built-in or the camera connected to the cellular phone 12. When the cellular phone user operates the cellular phone 12 according to the instruction to photograph the two-dimensional identification code 32, an image image of the two-dimensional identification code is input to the cellular phone. And the identification code which is this image data is transmitted to the authentication server 16. As shown in FIG. The authentication server 16 converts the image data of the transmitted two-dimensional identification code into a data format that can be validated to verify whether the identification code is valid. Subsequent processes in the second embodiment are the same as those in the first embodiment, and thus detailed description of the process will be omitted here.

In describing the second embodiment of the content transmission system according to the present invention, data to be downloaded using a URL or the like is described using a web page of a web server as an example, but the present invention is not only a web page of a web server. This may also apply to downloading data from a swap page on a WAP server.

7 is a diagram showing a card used in the content transmission system as the third embodiment of the present invention.

In the third embodiment of the content transmission system, an identification code 34 by a number is printed on the card 33. On the portion where the identification code 34 of the card 33 is printed, a lead-shaped opaque substance is applied as in FIG. 3A, and the identification code 34 cannot be recognized from the outside by itself. If the part coated with the lead substance is scraped off by a coin or the like, the identification code printed thereunder can be recognized from the outside.

In this embodiment, the mobile terminal user who obtains the card 33 downloads data of a web page arranged on a specific web server dedicated to content download, or sequentially selects a web link from a portal site for a mobile phone. Then, data of a web page arranged on a specific web server dedicated to content download is downloaded. For example, the URL printed on the card 33 is input by operating the button of the cellular phone 12. The mobile phone 12 in which the URL described in the card 33 is input from the button executes connection to the authentication server 16 via the telecommunications carrier network 13 and the Internet 15 based on the contents of the URL, and connects to the URL. The web page data in the authentication server 16 specified by the web browser is downloaded and displayed. In this web page, an instruction is given to the cellular phone user to input the identification code 34 of the number printed on the card 33 from the button of the cellular phone 12. When the mobile phone user operates the mobile phone 12 according to the instruction to input the two-dimensional identification code 34, the identification code is input to the mobile phone. The identification code is then sent to the authentication server 16. The authentication server 16 verifies whether the transmitted identification code is valid. Subsequent processes in the third embodiment are the same as those in the first embodiment, and thus detailed description of the process will be omitted here.

In describing the third embodiment of the content transmission system according to the present invention, data to be downloaded using a URL or the like is described using a web page of a web server as an example, but the present invention is not only a web page of a web server. This may also apply to downloading data from a swap page on a WAP server.
