It can be implemented as all kinds of wired and wireless networks such as mobile radio communication network or satellite communication network.

The terminal 100 may be implemented as a computer, a portable terminal, or a television that is connected to a server at a remote location through the network N, or may be connected to other terminals and servers. Here, the computer includes, for example, a notebook computer, a desktop computer, a laptop computer, and the like, each of which is equipped with a web browser (WEB Browser), and the portable terminal may be a wireless communication device , Personal Communication System (PCS), Global System for Mobile communications (GSM), Personal Digital Cellular (PDC), Personal Handyphone System (PHS), Personal Digital Assistant (PDA), International Mobile Telecommunication (IMT) Handheld based wireless communication devices such as W-CDMA (Code Division Multiple Access) -2000, W-CDMA (W-CDMA), Wibro (Wireless Broadband Internet) terminals, can do. In addition, the television may include an Internet Protocol Television (IPTV), an Internet Television (Internet Television), a terrestrial TV, a cable TV, or the like.

In addition, the prize providing device 300 is a means for providing data corresponding thereto in response to a request of the terminal 100. Prize providing device 300 is connected to the plurality of terminals 100 via a network (N), and provides the data corresponding to the request of each terminal 100 in the form of a document such as a web page terminal 100 Upon detecting an event occurring in, the application code list for the prize entry is provided to the terminal 100. In addition, the prize providing device 300 selects one of the plurality of application codes included in the application code list as a winning code to determine the user who selected the selected winning code as a winner so that the prize is provided.

Such prize providing device 300 includes a data providing unit 310 as shown in FIG. The data provider 310 extracts data corresponding to the request received from the terminal 100 and provides the extracted data to the terminal 100. In this case, the data provided by the data providing unit 310 may be, for example, a product sale page of an online shopping mall, but is not limited thereto.

In addition, the prize providing device 300 includes an event detecting unit 320. The event detector 320 is a means for detecting a predetermined input or operation performed by the terminal 100 through the data provided to the terminal 100 by the data providing unit 310. For example, the following event is detected. Data in document format provided by the data providing unit 310, for example, a web page scrolls down to a predetermined position in the terminal 100, or clicks an object displayed at a predetermined position of the web page provided by the data providing unit 310 Or drag and drop may be set as an event. Furthermore, an action of moving to another web page through a hyper-object included in a specific web page may be determined as an event, and an operation of purchasing a specific product through a specific web page may also be determined as an event. In addition, the web page location information (for example, a URL (Uniform Resource Locator), etc.) to select a command to register as a bulletin board bulletin of the social network service (SNS) provided by a third party server (not shown) The action may also be one of predetermined events. Furthermore, an event may be determined in which a user input signal indicating interest in a certain product is received on a specific web page. For example, when registering an item on a wish list of a user, such as a wish list, a wish list, or a 'favorite', such as a wish list, the event detection unit ( 320 may detect that an event has occurred.

When the event detecting unit 320 detects that the predetermined event occurs in the terminal 100 as described above, the applicant management unit 330 registers the user of the terminal 100 as an applicant. At this time, the entrant management unit 330 may automatically register a user of the terminal 100 in which an event is detected as an entrant, or a list of entry codes for prizes corresponding to data in which an event occurs so that a user may select a desired entry code. May be provided. Here, the application code list may include a plurality of application codes, and each application code may be provided in a selectable or impossible state. That is, the applicant managing unit 330 provides the application code selected once in the terminal 100 in a non-selectable state, and provides only a non-selected application code in a selectable state. When the plurality of prizes are provided, the applicant managing unit 330 may provide the terminal 100 with an entry code list including the same application codes for each of the prizes, in the entry code list corresponding to each prize. The selectable or unselectable state of the included application codes may be managed separately for each entry code list corresponding to each prize. In addition, the applicant management unit 330 manages the applicant list. The applicant list means a list of users who have applied for each prize, and when the applicant management unit 330 automatically registers the applicant at the same time as the event occurs, only the identification information of each applicant is registered in the applicant list, and the terminal 100 Receiving a selection input for any one of the selectable application codes included in the entry code list from), and managing the entrant, identifying the applicant who selected the entry code while switching the selected application code to the non-selectable state. Information can be stored in association with the selected entry code. Here, the list of applicants is managed separately for each prize, and since each prize is related to a specific prize, each applicant list is eventually associated with a different product (a product sold through a web page). Furthermore, the maximum number of applicants that can be registered in the applicant list may be limited, or the maximum number of applicants may be actively changed according to conditions. Here, the prize associated with any product may be the same product as the corresponding product.

And the prize providing device 300 includes a winner determination unit 340, the winner determination unit 340 determines the winner by selecting any one applicant from the applicant list provided by the applicant management unit 330. If only the identification information of the applicant is registered in the applicant list, the applicant is selected by selecting one of the identification information of the plurality of applicants, and when the identification information of the applicant and the applicant code selected by the applicant are stored in association with the applicant list, the applicant One of all the application codes included in the list is selected to determine the winning code, and the user corresponding to the identification information of the user stored in association with the winning code is determined as the winner, so that prizes can be provided accordingly. In this case, even if a plurality of prizes are paid, the winner determination unit 340 determines only one winning code, thereby minimizing involuntary involvement in the winning code selection process. As described above, the entrant management unit 330 includes a plurality of entry codes corresponding to each of the prizes to be configured with the same entry codes, so that even if only one winning code is determined, different winners for each prize may be determined. Can be.

In particular, in determining a winner of a prize for any prize, the winner determination unit 340 may differently determine the number of prize winners (ie, the number of prizes provided) according to the sales quantity of the prize. For example, in the winner determination unit 340, the unit sales quantity of the product and the number of unit winners corresponding thereto may be set in advance. For example, if five winners per 100 units of a certain amount of sales of a certain product are set in advance, and the total number of sales of any item is 10000, the number of winners to be determined by the winner determination unit 340 should be determined. Can be 500 people.

Furthermore, when the number of prize winners is actively changed according to the sales quantity of the product as described above, the number of applicants for the prizes may be changed together in proportion to the number of prize winners. For example, if the number of unit winners is set to 5 for 100 sales quantities of a certain product, and the maximum number of applicants is 500 when the number of winners is 5 again, when the sales quantity of the products reaches 200, correspondingly The number of winners for the prize associated with the prize will be increased to 10, so the maximum number of entries for the prize will be increased to 1000. That is, the applicant management unit 330 increases the number of users who can register in the applicant list from 500 to 1000, and provides the users with the change in the maximum number of applicants visually, thereby allowing users to enter a prize for each product. You can check the maximum number of people, and you can see that the maximum number of applicants fluctuates as the sales of products increase. In addition, even when providing the entry code list, the entry management unit 330 includes only the number of entry codes corresponding to the maximum number of entries in the entry code list. The number of can also be increased.

Hereinafter, the prize providing method using the prize providing apparatus 300 and the plurality of terminals 100 according to the embodiment of the present invention as described above will be described in more detail.

3A and 3B are flowcharts showing step by step methods of providing a prize according to an embodiment of the present invention, and FIG. 4 is an exemplary view illustrating a drawing process of the prize providing method according to an embodiment of the present invention.

As shown in FIG. 3A, the prize providing method according to an exemplary embodiment of the present invention begins with a step (S100) of receiving a web page transmission request from the terminal 100 to the prize providing apparatus 300. In this case, at least some of the web pages that may be provided to the terminal 100 may include content related to a predetermined product, and prizes subordinate to the respective products may be predetermined. For example, the web page provided to the terminal 100 may be a merchandise sales page that provides an image of the merchandise and detailed information of the merchandise for sale of the merchandise, and thus the merchandise associated with the content included in the web page. In each case, the prizes subordinate to the prizes may be predetermined.

On the other hand, when the data providing unit 310 of the prize providing device 300 receives a web page transmission request from the terminal 100, and provides the requested web page to the terminal 100 (S110).

At this time, the event detecting unit 320 of the prize providing device 300 determines whether an event occurs based on a signal received from the terminal 100 receiving the web page (S120). Here, the event detected by the event detector 320 may be predetermined in various ways as described above, and each event is associated with a predetermined product. For example, an event occurring in the product sale page for a specific product (exemplified as 'product A') or an event occurring for the product A may be preset to be associated with the product A. An event associated with product A is the click of a particular icon included in the product sale page containing the content for product A, or the purchase of product A occurring, or a feature that represents the user's interest in product A being selected. Can be set in advance. Accordingly, when an event occurs in the terminal 100, the event detecting unit 320 may determine which product the generated event is associated with. Here, the event detector 320 may detect an event occurrence based on, for example, a signal transmitted from a web browser of the terminal 100.

And when the event occurs in the web page associated with the specific product as described above, the applicant management unit 320 registers the user of the terminal 100 in which the event occurred as a contestant of the prize for the specific product (S130). This series of processes is performed repeatedly until the end of the application period (S140).

When the application period ends, the winner determination unit 340 draws some applicants from the applicant list to determine a winner (S150). At this time, the winner may be determined by a number proportional to the sales quantity of the product associated with the applicant list. For example, in the case of selecting a winner from the list of applicants for prize A, if one winner is selected for every 10 sales quantity of prize A, if the cumulative sales quantity of prize A is 1000, 10 winners are selected. .

Meanwhile, as shown in FIG. 3B, the prize providing method according to another exemplary embodiment of the present invention starts from step S200 in which a webpage transmission request is received from the terminal 100 to the prize providing apparatus 300. In this case, at least some of the web pages that may be provided to the terminal 100 may include content related to a predetermined product, and prizes subordinate to the respective products may be predetermined. For example, the web page provided to the terminal 100 may be a merchandise sales page that provides an image of the merchandise and detailed information of the merchandise for sale of the merchandise, and thus the merchandise associated with the content included in the web page. In each case, the prizes subordinate to the prizes may be predetermined.

On the other hand, when the data providing unit 310 of the prize providing device 300 receives a web page transmission request from the terminal 100, and provides the requested web page to the terminal 100 (S210).

At this time, the event detecting unit 320 of the prize providing apparatus 300 determines whether an event occurs based on a signal received from the terminal 100 provided with the web page (S220). Here, the event detected by the event detector 320 may be predetermined in various ways as described above, and each event is associated with a predetermined product. For example, an event occurring in the product sale page for a specific product (exemplified as 'product A') or an event occurring for the product A may be preset to be associated with the product A. A specific icon included in the product sale page including the content for the product A is clicked or a purchase occurs for the product A may be set as an event related to the product A in advance. Accordingly, when an event occurs in the terminal 100, the event detecting unit 320 may determine which product the generated event is associated with. Here, the event detector 320 may detect an event occurrence based on, for example, a signal transmitted from a web browser of the terminal 100.

On the other hand, when the event occurrence in the terminal 100 is detected in step S220, the applicant management unit 330 provides the terminal 100 with the entry code list for the predetermined prize corresponding to the product associated with the generated event (S230). . Herein, the prizes corresponding to the prizes may be predetermined in advance. For example, the same prize may be pre-matched for two different prizes, or different for each of the two different prizes. Two prizes may correspond. Furthermore, the same kind or different prizes may be pre-matched for two different prizes. And the application code list provided to the terminal 100 may be managed separately for each prize, or may be separately managed for different kinds of prizes. That is, the application code list may be separately managed by the same number as the number of prizes or separately by the same number as the number of prizes. In this case, the application code list managed separately means that the application codes included in each application code list are identical to each other, but the selection of each application code is made for each of the prizes or the prizes of the same kind.

And the applicant management unit 330 of the prize providing device 300 is selected from the application code of the selectable state included in the application code list provided to the terminal 100 in S230 (S240), the selected application code is not selectable Switch to the state (S250). Once the application code is selected at the terminal 100, the application code is immediately switched to the non-selectable state, so that each application code included in one application code list is not duplicated.

Subsequently, the applicant management unit 330 associates the identification information of the user received from the terminal 100 with respect to the application code selected in step S240 and stores the identification information in the applicant list. That is, for each selected application code, by storing the identification information of the selected user in association with each other, the application code and the applicant who selected the application code are stored in correspondence with each other. As a result, all the corresponding applicants are registered in the selected application code.

On the other hand, a series of processes of steps S200 to S260 may be repeatedly performed until the application period ends (S270). The entry period may be terminated at the same time for each prize.

If it is determined in step S270 that the entry period is finished, the winner determination unit 340 determines a part of the entry code among all the entry codes included in the entry code list as the winning code (S280). In this case, when there are a number of prizes or types, and each of the prizes or types of prizes corresponds to the entry code list, when there are a plurality of entry code lists, it is possible to determine a winning code common to the plurality of entry code lists. . That is, since the plurality of application code lists include a common application code, the same winning code can be determined for each prize even when the winning code is determined. In addition, the step of determining a part of the entry code included in the entry code list by the winner determination unit 340 as a winning code, may be made in the next step after generating the entry code list. As such, when the winning code is determined before the event proceeding, the winning result may be prevented in advance in consideration of the application situation.

Furthermore, the winner determination unit 340 determines the winner with the user identification information registered in the applicant list in response to the determined winning code so that prizes are paid (S290).

Another embodiment of the present invention described with reference to FIG. 3B is illustrated by exemplifying the bar shown in FIG. 4. A plurality of prizes (G) 'digital camera', 'Japan travel ticket' and 'amusement park discount ticket' are respectively associated with different products. For each, the application code list L including the same application code with each other is provided to the user. When an event for a product related to the 'digital camera' occurs in the terminal 100, the application code list corresponding to the 'digital camera' is provided to the terminal 100.

At the end of the entry period, one or more common winning codes will be determined for all three prizes. For example, if the entry code '20120013' is selected as the winning code, the entry code '20120013' is selected from the respective entry list for each prize, thereby corresponding to each user identification information registered in association with the entry code '20120013'. Each applicant will be determined to be a winner corresponding to the prize.

As such, by providing a list of entry codes including the same entry codes for a plurality of prizes and determining a winning code common to a plurality of prizes, the number of winning codes to be determined can be minimized to be involved in the winner selection process. Negation can be minimized. In addition, the number of winners can be adjusted within the planned range by providing the selection codes in a selectable / not selectable state so that duplicate selection of the entry codes is not allowed.

The prize providing method according to the embodiment of the present invention described with reference to FIGS. 3A and 3B and FIG. 4 may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by the computer. have. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes any information delivery media, including computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transport mechanism.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
