Description

  The present invention is an electronic lottery system that accepts a large number of applications using electronically generated image data and determines whether or not to win a lottery based on electronically generated image data when planning to provide presents etc. by lottery And an electronic lottery method.

  Conventionally, with regard to information processing technology mediated by image data, for example, when a photographic image of a product is taken with a camera, a URL (Uniform Resource Locator) is extracted from the image data, and information detection that can access a product purchase site A system is known (for example, refer to Patent Document 1). In this information detection system, URL information is inserted in the form of a digital watermark in advance in a photographic image, and when image data obtained by photographing this is analyzed, URL information is extracted therefrom. . In addition, when the user accesses the purchase site, there is an advantage that a lottery can be received in addition to the purchase of the product.

In addition to printing advertising images and advertising information on advertising media, traditionally adding optically readable two-dimensional codes together adds value other than advertising to advertising media. There is a distribution article for sales promotion (see, for example, Patent Document 2). This distributed article can be used as an advertising print surface, such as a fan or fan, and can be used as an advertising print surface. By using a two-dimensional code printed on it, it can be transferred from a mobile phone to a website on the Internet. It can be accessed. When users access the site, they can interact with entertainment content such as fortune-telling and lottery. Therefore, there is an advantage that the distributed article can be used not only as an advertisement but also as an entrance for attracting to the website.
JP 2005-184158 A Utility Model Registration No. 3109395

  As described above, the technology for extracting information from image data such as a digital watermark and a two-dimensional code, and performing information communication using the information or performing a lottery, allows each user to enter a URL character by character using the keyboard. It can be said that it is excellent in convenience and speed of information transmission because it does not require a detailed input operation such as inputting, and can easily acquire information only by photographing with a camera.

  In recent years, for example, an attempt has been made to utilize image data for the process of collecting a wide range of applications from the public when offering a present product and selecting a winner from the application. In other words, a two-dimensional code is printed on a printed matter such as a magazine together with a lottery article for a present product, and the purchaser of the magazine can use the two-dimensional code to access a lottery application website. There is. In this usage example, an applicant can be attracted to a server site for application using a two-dimensional code, and an application can be accepted there. Since such an application form is simpler than an application form in which an application ticket cut from a magazine is attached to a postcard and posted, there is an advantage that more applicants can be easily collected.

  However, since the lottery requires a certain degree of strictness and fairness, if the lottery's strictness or fairness is hindered, it will be overwhelmed. For example, even if the application qualification for the lottery is limited to magazine purchasers, if the same magazine is transferred from the purchaser to another person, it is possible for other than the purchaser to apply. It will fade. Therefore, at present, the only effective measure is to pull back the application ticket from the magazine and send it back to the application procedure. However, there is a problem that such an application procedure is complicated.

  Therefore, an object of the present invention is to provide a technique that can guarantee the strictness and fairness of the lottery without impairing the convenience.

  First, the present invention provides an electronic lottery system that is excellent in the convenience of application, the strictness and fairness of the lottery. Secondly, the present invention provides an electronic lottery method. The electronic lottery method can be implemented using the electronic lottery system of the present invention.

  In the electronic lottery system of the present invention, the application from the applicant is only to transmit the image data via the communication line, and the operation is extremely simple. The image data created by the applicant is registered as application data when it is received.

  The lottery mechanism is that original data is image data created privately by the organizer, and the result is determined by comparing the image feature amount with the image feature amount of the application data. In the image data created by the applicant, an image feature amount reflecting the applicant's own behavior appears. For example, when image data is created by photographing a certain subject, various elements such as the shape and size of the subject used by each individual applicant vary from subject to subject. Such a difference appears as a difference in image feature amount for each application data. In addition, if a lottery rule is established such that the original image data and the image feature quantity close to the original data are selected from a large number of application data, no arbitrary intervention is involved in the lottery mechanism and the strictness of the lottery is maintained. Will be drunk. Further, the applicant is satisfied with the fact that his / her actions can be reflected in the determination of the success / failure because the success / failure is determined based on the feature amount of the image created by himself / herself.

  On the other hand, if another person creates image data using the same subject, the application data having the same image feature amount will be registered redundantly, but a rule is given to give priority to the first one in the electronic lottery system. If this is the case, the application submitted later will be excluded from the prize, so the fairness of the lottery will be maintained.

  When deciding whether or not to win the lottery, it is intuitively easy to understand the rule that the original data and the image feature amount approximate to each other, or the winning rank such as 1 or 2 is assigned in order of the closest image feature amount. However, since the original data created by the organizer is not disclosed, the applicant can imagine what kind of image data should be created to approximate the image feature amount, and maintain a certain amount. It is interesting that you can create image data for application with a sense of tension and expectation.

  In particular, in the process of generating image data as original data and application image data, the application ticket is torn into a stub if it is an aspect of imaging a stub formed by artificially tearing a predetermined application ticket. The image shape greatly affects the image feature amount. For this reason, the applicant can determine whether or not the lottery is successful due to his / her own action when the application ticket is torn, and can obtain the satisfaction of participating in the lottery.

  In addition, if it is an aspect that captures a torn stub at the time of application, even if another person later images and applies for the same stub, it is possible to establish a rule that excludes other than the first arrival in the electronic lottery system as described above. If so, the fairness of the lottery can be maintained.

  When distributing an application ticket as a printed matter such as a magazine, various information can be inserted into the ticket surface in the form of a digital watermark. Unlike two-dimensional codes, digital watermarks can be inserted in the form of a continuous pattern within a certain printing range, so as long as the coded pattern exists there even after being torn into a stub From there, you can extract information. On the other hand, two-dimensional code is greatly different in that it becomes unreadable if a part of its entire area is missing and makes no sense.

  In any case, if information is inserted in the form of a digital watermark on the ticket face of the application ticket, the information extracted from the original data can be compared with the information extracted from the application data. Therefore, when two or more different pieces of application data with the same image feature amount as the original data are found, the priority cannot be determined only by the image feature amount, but it can be obtained from the digital watermark as another reference there. Applying the information comparison results will easily solve the priority issue. The digital watermark information may be extracted from the registered application data, or transmitted from the image data to be applied to the applicant side via the communication line together with the image data. It is also possible to use this mode.

  In addition, it is determined whether or not the digital watermark information extracted from the application data (or image data for application) matches the identification information specified in advance, and as a result, registration is made only for the application data. If it is an allowed mode, it can be easily discriminated whether or not a printed matter such as a magazine is an object of a lottery plan. Such an aspect is effective when the application qualification is given as a magazine purchaser's privilege.

  Further, in the electronic lottery system of the present invention, prior to the generation of the application image data, it is possible to notify a serial number assigned individually to an applicant who has obtained an application ticket. In addition, when the serial number is entered on the ticket face of the imaged application stub, the entered serial number can be read based on the application data. In the electronic lottery system, if it is impossible to interpret the serial number of the application data for which the winning is determined, the application data can be excluded from the winning object.

  In the electronic lottery system of the present invention, duplicate application using the same stub is excluded. The serial number can be used as a measure to further strengthen this exclusion principle. That is, when the serial numbers read for a plurality of pieces of application data match each other, at least application data other than the application data registered first is excluded from the winning targets. In this case, even if a duplicate application using the same stub remains as a winning candidate, if the serial number is finally the same, it will be excluded from being selected as a duplicate application.

In the electronic lottery system of the present invention, the following two patterns are prepared for the winning notification to the winner.
(Pattern 1)
One is a pattern for registering application data in association with information unique to the applicant. In this pattern 1, it is required to send information such as an e-mail address together with image data to the applicant. When the winning is determined, the winning result is notified to the applicant based on the unique information associated with the winning application data. If an e-mail address is registered, a winning notification mail is sent to that address. For this reason, the winner is informed of the winning result as soon as possible, and can enjoy the privilege as early as that.

(Pattern 2)
The other is a pattern in which when the registration of the application data is completed, the applicant is notified of the location of information that enables the individually assigned lottery results to be viewed. In this pattern 2, the applicant is not required to send personal information. When winning is decided by lottery, the applicant (winner) who has won the prize can confirm the winning result by recording the information that enables the viewing of the lottery result at the location notified earlier. it can.

  As described above, according to the present invention, not only can more applications be collected by a simple procedure, but also the strictness and fairness of the lottery can be reliably maintained.

  In addition, the lottery method adopted by the present invention is interesting in that the criteria for deciding whether or not to win the lottery depends on the applicant's own actions, so that he / she participates in the lottery instead of relying on others.

  Hereinafter, an electronic lottery system of the present invention and an electronic lottery method implemented using the system will be described.

  FIG. 1 is a diagram schematically showing an electronic lottery system serving as a hardware resource for carrying out the electronic lottery method. This electronic lottery system includes, for example, a portable information terminal 1, a base station 101, a network 102, and a server computer 100.

  The portable information terminal 1 is a portable information terminal device having a function of performing display based on HTML data on its display screen, and here, a portable telephone is taken as an example. The portable information terminal 1 also has a function as a computer, and includes a system resource that appropriately reads an application program stored in a built-in storage device (memory) or the like and executes it.

  In order to participate in the electronic lottery performed using the electronic lottery system of the present embodiment, the mobile information terminal 1 needs to have a camera function. The camera function may be any function that can convert an optically photographed image into digital image data, such as a CCD camera. Note that the portable information terminal 1 is not limited to a mobile phone, and may be a portable computer having a communication function, a notebook personal computer, or the like.

  The base station 101 includes an antenna for performing communication with the portable information terminal 1. The base station 101 is connected to a network 102 such as the Internet, for example, and relays data communication performed through the network 102 by the portable information terminal 1.

  A server computer (hereinafter referred to as “server”) 100 is connected to the network 102. The server 100 has a function of performing data communication with the portable information terminal 1 via the base station 101 and the network 102, and also has various processing functions for executing an electronic lottery program as a computer.

  Next, an outline of an electronic lottery method performed using the electronic lottery system of FIG. 1 will be described. FIG. 2 to FIG. 5 are diagrams continuously showing example procedures when applying for electronic lottery. The following describes the application procedure.

  For example, it is assumed that a plan for providing a present using an electronic lottery sponsored by a lottery execution subject is published in a magazine. As shown in FIG. 2A, the magazine corresponding to the present project includes a present application page, and the present application page is surrounded by, for example, a cut line or a perforation. An application ticket T having an area is printed. The applicant cuts out the portion of the application ticket T along the cut line (or perforation) from the present application page of the purchased magazine. By prompting the cut in this way, the original prototype of the application ticket T can be unified to some extent.

  Further, as shown in FIG. 2B, a magazine code and a rotation angle detection pattern are printed on the cut-out application ticket T in the form of a digital watermark. Needless to say, this information cannot be identified with the naked eye. The size and shape of the application ticket T are not particularly limited, but an example is preferably a shape close to a square and a size that can be held by a general adult with both hands.

  As shown in FIG. 3, the applicant then tears the cut application ticket T roughly in half. In other words, tear it in two with your own hands. At this time, no information such as an auxiliary line for guiding tearing or an arrow for instructing the tearing direction is printed on the ticket surface of the application ticket T. However, on the magazine gift application page, “Please tear as you like. It can be in any direction, vertical, horizontal, diagonal. Your fate will determine whether or not you will receive a present.” ”May be entered. In this case, since it is possible to give a certain tension and expectation to the applicant when the application ticket T is torn, it is possible to deepen interest in the lottery or to make the player feel interesting from this stage. In any case, after that, the applicant uses the larger one of the half of the application ticket T that has been torn off as the application stub, that is, the application stub.

  When applying for a present, the applicant incorporates an electronic lottery application program in the portable information terminal 1 owned by the applicant. When the portable information terminal 1 is a mobile phone, the application program can be downloaded from the server 100 and acquired. Therefore, information related to a dedicated site for providing an application program for the portable information terminal 1 is recorded in the server 100 in the HTML data format. The magazine present application page describes a URL (uniform resource locator) of a dedicated site where such an application program can be downloaded.

  When the applicant operates the portable information terminal 1 to start an application program for electronic lottery, network communication is executed between the portable information terminal 1 and the server 100. When there is an access accompanying execution of an application program from the portable information terminal 1, the server 100 determines a serial number for individually identifying the applicant and notifies the applicant's portable information terminal 1 of this. The applicant confirms the serial number notified from the server 100 on the display screen of the portable information terminal 1. Such processing on the program will be further described later.

  Next, as shown in FIG. 4, the applicant enters the notified serial number on the face of the application stub F using a writing instrument. The position to be filled in and the size of characters are not particularly limited, but it is desirable to fill in a size that can be read by image recognition. Information such as a serial number entry sample can be written on the magazine gift application page. In the drawing, for convenience, the digital watermark pattern is shown in a dark color, but in reality, the digital watermark can be printed using a light color such as yellow or light blue. Accordingly, the applicant can easily enter the serial number using a writing instrument such as a pencil or a ballpoint pen.

  Then, as shown in FIG. 5, the applicant photographs the application stub F using the camera function of the portable information terminal 1. At this time, the applicant adjusts the distance between the application stub F and the camera so that the entire application stub F fits within the imaging area of the built-in camera.

  After photographing the application stub F, the applicant transmits photographed image data to the server 100 using the communication function of the portable information terminal 1. The transmitted image data is received by the server 100 and registered as application data.

  The above is the outline of the application procedure for the electronic lottery. The application procedure performed by the applicant using the portable information terminal 1 and all processes such as image data reception, application data registration, and lottery execution performed by the server 100 are performed. It is processed on a program executed by the electronic lottery system.

  FIG. 6 is a block diagram illustrating a configuration example of a program that operates in the portable information terminal 1 and the server 100, respectively. The portable information terminal 1 includes a wireless (RF) communication module in addition to hardware resources such as a CPU (Central Processing Unit) and a memory (not shown). The portable information terminal 1 can execute an application program using a built-in hardware resource, and can connect to the Internet 102 using a wireless (RF) communication module along with the execution. The server 100 also includes hardware resources such as a CPU (Central Processing Unit), a memory, a hard disk, and a bus (not shown). In addition to executing the electronic lottery program using the hardware resources, the server 100 can connect to the Internet 102 through a network interface (not shown).

  The portable information terminal 1 incorporates a portable information terminal system processing unit 10 as an application program for electronic lottery application. The portable information terminal system processing unit 10 is assigned a function for applying for lottery in the electronic lottery system of FIG. 1 and receiving notification of the lottery result.

  The server 100 incorporates a server system processing unit 20 as a program for executing electronic lottery. The server system processing unit 20 accepts an application in the electronic lottery system of FIG. 1, registers and manages the accepted application data, executes a lottery to determine whether it is successful or not, and determines the lottery result. It has a function to notify.

  Furthermore, the portable information terminal system processing unit 10 has a plurality of processing units, specifically, a serial number issue request processing unit 11, a message reception processing unit 12, an image photographing processing unit 13, an image data transmission processing unit 14, A URL reception processing unit 15 and a Web browser activation processing unit 16 are included.

  When the user of the portable information terminal 1 operates the operation key 17, the portable information terminal system processing unit 10 activates the functions of various processing units accordingly. Further, information regarding the process or result of processing performed in various processing units is displayed on the screen display unit 18 of the portable information terminal 1. The user can operate the portable information terminal system processing unit 10 in the portable information terminal 1 by operating the operation key 17 while confirming the display on the screen display unit 18.

  The server system processing unit 20 also has a plurality of processing units, which are roughly divided into four processing units. Specifically, the serial number issuance processing unit 22, the digital watermark processing unit 23, the application data registration processing unit 24, and the winning processing unit 25. Among these four processing units, the digital watermark processing unit 23, the application data registration processing unit 24, and the winning processing unit 25 each further include a plurality of processing units.

  First, the digital watermark processing unit 23 includes an image data reception processing unit 26, a digital watermark decoding processing unit 27, an ID confirmation processing unit 28, and a URL reply processing unit 29. The application data registration processing unit 24 includes a similar image search image feature amount extraction processing unit 30 and a database registration processing unit 31. The winning processing unit 25 includes a similar image search image feature amount extraction processing unit 32, a winning stub registration processing unit 33, a similar image search processing unit 34, a winning determination processing unit 35, and a winning contact processing unit 36. .

  Next, details of various processes executed in the electronic lottery system will be described. Further, the electronic lottery method performed using the electronic lottery system is clarified by the following description.

[First Embodiment: Pattern 1]
7 and 8 are sequence diagrams showing an example of the electronic lottery execution procedure (pattern 2) in the first embodiment. FIG. 7 shows the procedure from step S01 to step S15, and the procedure from step S16 to step S23 following this is shown in FIG. 7 and 8, the processing units included in the digital watermark processing unit 23, the application data registration processing unit 24, and the winning processing unit 25 are not shown in order to prevent complication.

Step S01: When a user who is an applicant for lottery operates the operation key 17 of the portable information terminal 1, an application program for electronic lottery is activated in the portable information terminal 1.
Step S02: When the application program is activated, the serial number issuance request processing unit 11 of the portable information terminal system processing unit 10 accesses the server 100 and issues a serial number to the serial number issuance processing unit 22 of the server system processing unit 20 Request.
Step S03: The serial number issuance processing unit 22 that has received the request issues a unique serial number updated for each access, and transmits this to the portable information terminal 1. Communication between the portable information terminal 1 and the server 100 is performed via the Internet 102 described above.

  Step S04: The message reception processing unit 12 of the portable information terminal system processing unit 10 receives the serial number transmitted from the server 100 side, and causes the screen display unit 18 to display the serial number. At this time, a shooting button is also displayed on the screen display unit 18. The shooting button displayed here assigns, for example, a shutter function for performing camera shooting to a specific operation key 17.

Step S05: When the applicant confirms the serial number assigned to himself / herself based on the display on the screen display unit 18, he enters it in the application stub F which has been broken, and operates the operation key 17 corresponding to the photographing button.
Step S06: When the operation key 17 corresponding to the photographing button is operated, the image photographing processing unit 13 activates the camera of the portable information terminal 1 and photographs the application stub F in which the serial number has been entered. When photographing of the application stub F is completed, the generated image data is temporarily buffered in an image memory built in the portable information terminal 1. At this time, an auxiliary shooting frame may be displayed on the screen display unit 18. Alternatively, when the operation key 17 corresponding to the shooting button is operated, the camera is first activated to display a finder image on the screen display unit 18, and when the applicant operates the operation key 17 corresponding to the shooting button again. A mode in which photographing is performed may be used.

Step S07: When the image photographing processing unit 13 finishes photographing, the screen display unit 18 is switched to an e-mail address input screen. At this time, the transmission button after the input is also displayed on the screen display unit 18. A mode in which a message such as “Please input an e-mail address for winning notification” is displayed together with this send button may be used.
Step S08: The applicant inputs his / her e-mail address according to the display on the input screen, and operates the operation key 17 corresponding to the send button.

  Step S09: When the operation key 17 corresponding to the transmission button is operated, the image data transmission processing unit 14 transmits the image data buffered in the image memory to the server 100 together with the input e-mail address. .

  Step S10: The e-mail address and image data transmitted to the server 100 are received by the image data reception processing unit 26 of the digital watermark processing unit 23. The digital watermark decoding processing unit 27 extracts a magazine ID (Identification) and a rotation angle embedded in the transmitted image data in the form of a digital watermark. The magazine ID is identification information indicating that it corresponds to a plan for providing a present using the electronic lottery system of the present embodiment.

  The rotation angle is a parameter extracted from a rotation angle detection pattern embedded in the form of a digital watermark. This parameter serves as an index for measuring how much the image at the time of photographing is displaced in the circumferential direction with respect to a reference angle that is predetermined at the time of printing. The difference in the rotation angle is based on the fact that the relative relationship between the direction of the optical axis of the camera at the time of shooting and the direction of the application stub F differs for each individual applicant. Note that any method for extracting an ID from image data or extracting a rotation angle using a digital watermark is well known, and the details thereof are omitted here.

  However, depending on the quality of the image data, the area (number of pixels) in which the application stub F is reflected is too small for the entire image data (for example, a pixel area of 640 dots × 840 dots), or the focus of the photographed image is blurred. Therefore, when the application stub F cannot be identified as an image, the digital watermark processing unit 23 may not be able to extract the magazine ID or rotation angle. Therefore, in step S10, it is determined whether or not the magazine ID and the rotation angle can be extracted. As a result, if both the magazine ID and the rotation angle can be extracted, the process proceeds to step S13. Proceed to the next step S11.

First, a case where either the magazine ID or the rotation angle cannot be extracted in step S10 will be described.
Step S11: The digital watermark processing unit 23 transmits message information such as “please shoot and send again” to the applicant's portable information terminal 1.
Step S12: In the portable information terminal 1, the message reception processing unit 12 receives the message information from the server 100 and displays it on the screen display unit 18. At the same time, the shooting button is displayed on the screen display unit 18. Subsequent application procedures are performed in accordance with steps S05 and later described above.

  If both the magazine ID and the rotation angle can be extracted in step S10, the following procedure is performed. The same applies when the magazine ID and the rotation angle are successfully extracted from the image data retransmitted through step S11.

  Step S13: The ID confirmation processing unit 28 of the digital watermark processing unit 23 confirms whether or not the extracted magazine ID matches that of the magazine corresponding to the present present project. As a result, if the magazine IDs match, the process proceeds to step S16 (FIG. 8). If any of the magazine IDs cannot be extracted, the process proceeds to the next step S14.

If the magazine IDs do not match, the following processing is performed.
Step S14: The ID confirmation processing unit 28 transmits message information such as “magazine ID is different” to the portable information terminal 1 of the applicant.
Step S15: In the portable information terminal 1, the message reception processing unit 12 receives the message information from the server 100 and displays it on the screen display unit 18. At this time, an end button may be displayed on the screen display unit 18 together. In this case, when the applicant confirms the displayed message, the application program can be ended by operating the operation key 17 corresponding to the end button.

On the other hand, when the magazine IDs match, the following processing is performed.
Step S16: The digital watermark processing unit 23 delivers the image data to the application data registration processing unit 24.
Step S17: Upon receiving the image data, in the application data registration processing unit 24, the image feature amount extraction processing unit 30 for similar image search extracts the image feature amount from the image data. The database registration processing unit 31 registers the extracted image feature quantity in the present application database together with the image data. Note that the image feature amount is a plurality of parameters used in the similar image search. In the present embodiment, parameters corresponding to the shape when the application stub F is torn off, the size (area) of the application stub F, and the like are handled as image feature amounts. This is for utilizing the fact that the tearing method when tearing off the original application ticket T is different for each applicant and reflecting the difference in the image feature amount caused thereby in the lottery result.

In addition, the following information is included in the application data (per applicant) registered in the database at this time.
(1) Entry number (assigned to each applicant in the server system processing unit 20)
(2) Serial number (issued by serial number issuance processing unit 22)
(3) Rotation angle (digital watermark)
(4) Image feature amount (used for similar image retrieval)
(5) Date and time of registration (for example, a time stamp such as AD / month / day / hour / minute / second)
(6) Email address (sent by applicant)

Step S18: When registration in the application database is completed, the application data registration processing unit 24 transmits a registration completion message to the mobile information terminal 1 of the applicant.
Step S19: In the portable information terminal 1, the message reception processing unit 12 receives the registration completion message from the server 100 and displays it on the screen display unit 18. For example, a message such as “registration completed” is displayed on the screen display unit 18. At the same time, an end button is displayed on the screen display unit 18.
Step S20: Upon confirming the displayed message, the applicant operates the operation key 17 corresponding to the end button to end the application program.

When the registration of the application data is completed through the above procedure, the winning processing unit 25 performs the winning processing procedure.
Prior to the execution of the winning process, a winning stub is registered by a lottery execution entity that hosts the lottery. In other words, the lottery executing entity that hosts the lottery tears the application ticket T manually under the control of the lottery and makes it a winning stub (the original original). The lottery execution subject may tie up with a specific magazine and tear off the application ticket T to a specific person (for example, entertainer, athlete, etc.) taken up in the article of the magazine. In this case, an applicant who is a magazine purchaser can be more interested in the lottery result.

  In any case, the winning stub created by the lottery execution subject is registered in the database without being disclosed. For example, the lottery execution subject takes a winning stub using the camera function of the portable information terminal 1 under the management, and transmits the image data to the server 100 as the winning stub. In the server 100, the received image data is handled as a winning stub (original data) by the winning stub registration processing unit 33, and is registered separately from the application data.

The registered original data includes at least the following contents.
(1) Rotation angle (digital watermark)
(2) Image feature amount (used for similar image search)
In addition, about the process which registers a winning stub as original data in a database, a part of process until it registers application data demonstrated previously can be diverted. However, since it is not necessary for the lottery execution subject to enter a serial number in the application stub F or input an e-mail address, these processes are appropriately omitted.

On the premise of registering the above-mentioned winning stub, the following winning process is performed in the winning processing unit 25 of the server system processing unit 20. The following winning process is executed after the end of a predetermined present application period, for example.
Step S21: First, the image feature quantity extraction processing unit 32 for similar image search performs a similar image search, and an image (application data) whose image feature quantity approximates the winning stub (original data) from the present application database. elect. The approximate value for the image feature amount of the winning stub is provided with a certain range in advance. For this reason, it is expected that a plurality of pieces of application data that fall within the approximate range of the image feature amount are selected in the similar image search.

The selected application data is ranked according to the following criteria.
First, ranking is performed in the order in which the image feature amounts are approximated, and the first, second, third,..., N, etc. are selected in order from the closest image feature amount. It should be noted that the lottery execution entity can determine the number up to which to win.

  When multiple application data having the same image feature amount are found within the winning range, priority is given to the same (or close) rotation angle as the winning stub. For this reason, even if they have the same image feature amount, the order of those having a greatly different rotation angle is lowered. Furthermore, if the rotation angle is the same, the order of application will be the first. As a result, even if the image feature amount is the same, it may fall out of the winning range due to the difference in the rotation angle, so the applicant will not be disappointed not only when tearing the application ticket T, but also when shooting this, so lottery The tension and interest in the will increase. In addition, in order to gain an advantage in the lottery, it is necessary to purchase a magazine first and apply before other people.

  If the ranking is arranged according to the above criteria, a temporary winning is determined based on the ranking. Thereafter, the winning determination processing unit 35 checks whether or not a serial number is entered in the image data that has been temporarily selected. This confirmation is performed by recognizing the serial number entered by the applicant. As a result, a process in which a serial number is not entered or a letter that is entered but cannot be recognized is not selected. As a result, when there is a vacancy in the winning frame, the application data that has been ranked first is advanced in turn and won.

  Step S22: When the winning result is confirmed, the winning contact processing unit 36 gives a winning notification. This winning notification is made by sending an e-mail to a registered e-mail address. In the e-mail, a URL dedicated to the winner is entered.

  Step S23: The applicant who has received the winning notification by e-mail (here, the winner) accesses the designated URL and inputs necessary items (for example, address, name, etc.) there. In response to this, the lottery execution entity sends a specified present item (1st to n) to the winner.

[Second Embodiment: Pattern 2]
Next, 2nd Embodiment of the electronic lottery method performed using an electronic lottery system is described. In the first embodiment, personal information such as an e-mail address has to be input at the time of application. In the second embodiment, transmission of personal information is not requested except for the winner. Note that, in the following description, when the same matters as in the first embodiment are applied, the redundant description will be appropriately omitted unless particularly necessary.

  9 and 10 are sequence diagrams illustrating an example of the electronic lottery execution procedure (pattern 2) in the second embodiment. FIG. 9 shows the procedure from step S101 to step S115, and the procedure from step S116 to step S126 following this is shown in FIG. 9 and 10, the processing units included in the digital watermark processing unit 23, the application data registration processing unit 24, and the winning processing unit 25 are not shown in order to prevent complication.

Step S101: When the applicant (user) operates the operation key 17 of the portable information terminal 1, an application program for electronic lottery is activated in the portable information terminal 1.
Step S102: When the application program is activated, the serial number issuance request processing unit 11 of the portable information terminal system processing unit 10 accesses the server 100 and issues a serial number to the serial number issuance processing unit 22 of the server system processing unit 20 Request.
Step S103: The serial number issuance processing unit 22 that has received the request issues a unique serial number updated for each access, and transmits this to the portable information terminal 1.

  Step S104: The message reception processing unit 12 of the portable information terminal system processing unit 10 receives the serial number transmitted from the server 100 side, and causes the screen display unit 18 to display the serial number. At this time, a shooting button is also displayed on the screen display unit 18.

Step S105: When the applicant confirms the serial number assigned to himself / herself on the basis of the display on the screen display unit 18, the applicant enters the broken application stub F and operates the operation key 17 corresponding to the photographing button.
Step S106: When the operation key 17 corresponding to the photographing button is operated, the image photographing processing unit 13 activates the camera of the portable information terminal 1, and photographs the application stub F in which the serial number has been entered.

Step S107: When the image photographing processing unit 13 finishes photographing, the screen display unit 18 is switched to a transmission button display screen.
Step S108: The applicant operates the operation key 17 corresponding to the send button.

  Step S109: When the operation key 17 corresponding to the transmission button is operated, the image data transmission processing unit 14 transmits the image data buffered in the image memory to the server 100.

  Step S110: The e-mail address and image data transmitted to the server 100 are received by the image data reception processing unit 26 of the digital watermark processing unit 23. Also, the digital watermark decoding processing unit 27 extracts a magazine ID and a rotation angle embedded in the transmitted image data in the form of a digital watermark.

If either the magazine ID or the rotation angle cannot be extracted in step S110, the following procedure is performed.
Step S111: The digital watermark processing unit 23 transmits message information such as “Please shoot again and send” to the applicant's portable information terminal 1.
Step S112: In the portable information terminal 1, the message reception processing unit 12 receives the message information from the server 100 and displays it on the screen display unit 18. At the same time, the shooting button is displayed on the screen display unit 18. Subsequent application procedures are performed in accordance with step S105 and subsequent steps described above.

  If both the magazine ID and the rotation angle can be extracted in step S110, the following procedure is performed. The same applies to the case where the magazine ID and the rotation angle are successfully extracted from the image data retransmitted through step S111.

  Step S113: The ID confirmation processing unit 28 of the digital watermark processing unit 23 confirms whether or not the extracted magazine ID matches that of the magazine corresponding to the present present project. As a result, if the magazine IDs match, the process proceeds to step S116 (FIG. 10). If any of the magazine IDs cannot be extracted, the process proceeds to the next step S114.

Step S114: The ID confirmation processing unit 28 transmits message information such as “Magazine ID is different” to the portable information terminal 1 of the applicant.
Step S15: In the portable information terminal 1, the message reception processing unit 12 receives the message information from the server 100 and displays it on the screen display unit 18. At this time, an end button may be displayed on the screen display unit 18 together.

Step S116: If the magazine IDs match in step S113, the digital watermark processing unit 23 delivers the image data to the application data registration processing unit 24.
Step S117: When receiving the image data, in the application data registration processing unit 24, the image feature amount extraction processing unit 30 for similar image search extracts the image feature amount from the image data. The database registration processing unit 31 registers the extracted image feature quantity in the present application database together with the image data.

In the second embodiment (pattern 2), the following information is included in the application data (per applicant) registered in the database.
(1) Entry number (assigned to each applicant in the server system processing unit 20)
(2) Serial number (issued by serial number issuance processing unit 22)
(3) Rotation angle (digital watermark)
(4) Image feature amount (used for similar image retrieval)
(5) Date and time of registration (for example, a time stamp such as AD / month / day / hour / minute / second)
(6) Web page URL for winning contact (issued individually by server system processing unit 20)

Step S118: When the registration in the application database is completed, the application data registration processing unit 24 transmits the registration completion to the URL reply processing unit 29 of the digital watermark processing unit 23.
Step S119: The URL reply processing unit 29 returns an applicant contact URL to the applicant's portable information terminal 1.

Step S120: In the portable information terminal 1, the URL for the applicant contact returned from the server 100 is received by the URL reception processing unit 15, and the received URL is transferred to the Web browser activation processing unit 16.
Step S121: The web browser activation processing unit 16 activates a web browser application incorporated in the portable information terminal 1 and accesses the transferred URL.
Step S122: With the start of the Web browser application, the Web page placed at the URL of the access destination is displayed on the screen display unit 18.

  Step S123: The applicant bookmarks the Web page displayed on the screen display unit 18. The bookmark is a function incorporated in the Web browser application, and is generally spread with a name such as “favorite”. When the applicant confirms the Web page, the applicant operates the operation key 17 corresponding to the end button to end the application program.

  When the registration of the application data is completed through the above procedure, the winning processing unit 25 performs the winning processing procedure. Also in the second embodiment, the registration of winning stubs performed as a premise of the winning process is performed in the same manner as in the first embodiment.

  Step S124: The image feature amount extraction processing unit 32 for similar image search performs a similar image search, and selects an image (application data) whose image feature amount approximates the winning stub (original data) from the present application database. To do.

  The selected application data is ranked according to the same criteria as in the first embodiment, and after the provisional winning is determined, the winning result is confirmed through confirmation of the serial number.

  Step S125: When the winning result is confirmed, the winning contact processing unit 36 gives a winning notification. This winning notification is performed by uploading a winning result to an applicant contact URL given to each applicant.

  Step S126: When the winning announcement date arrives, the applicant accesses the applicant contact URL bookmarked on the portable information terminal 1, and confirms the contents of the Web page. For example, if a message such as “Congratulations. You have won n, etc.” is displayed, the applicant (the winner here) will enter the necessary information (such as e-mail address, address, name, etc.) for the first time there. To do. In response to this, the lottery execution entity sends a specified present item (1st to n) to the winner.

  By adopting the electronic lottery method described above (first and second embodiments), it is possible to eliminate applications by persons other than the magazine purchaser, and duplicate applications by the same person or multiple persons using the same application ticket. it can.

[Third Embodiment]
Next, a third embodiment of the electronic lottery method will be described. The electronic lottery method of the third embodiment can be realized by modifying a part of the electronic lottery system used in the first and second embodiments or adding a function thereto. This will be specifically described below.

  In the first and second embodiments described above, only the image data is transmitted from the portable information terminal 1 to the server 100. However, in the third embodiment, the portable information terminal 1 decodes the digital watermark, and there, The extracted magazine ID and rotation angle are transmitted from the portable information terminal 1 to the server 100 together with the image data.

  In this case, as a configuration of the electronic lottery system, for example, the function of “digital watermark decoding processing unit” is added to the portable information terminal system processing unit 10 shown in FIG. The “digital watermark decoding processing unit” mentioned here may be any one having the same function as the digital watermark decoding processing unit 27 of the server system processing unit 20 described in the first and second embodiments.

  In the third embodiment, the image data transmission processing unit 14 of the portable information terminal system processing unit 10 is changed to a “data transmission processing unit”. Such a “data transmission processing unit” has a function of transmitting, to the server 100, the magazine ID and the rotation angle extracted by the “digital watermark decoding processing unit” together with the image data taken by the portable information terminal 1. Have.

  On the other hand, for the server system processing unit 20, the image data reception processing unit 26 of the digital watermark processing unit 23 is transformed into a “data reception processing unit”. The function of the digital watermark decoding processing unit 23 may not be an essential element on the server 100 side.

  As described above, the electronic lottery method according to the third embodiment is implemented according to the following sequence after a part of the configuration of the electronic lottery system is modified or added.

First, with respect to the pattern 1 (first embodiment) shown in FIGS. 7 and 8, some of the steps are modified as follows.
In step S06 in FIG. 7, when the operation key 17 corresponding to the shooting button is operated, the image shooting processing unit 13 activates the camera of the portable information terminal 1 to shoot the application stub F in which the serial number has been entered. . When the application stub F is photographed, the generated image data is temporarily buffered in the image memory built in the portable information terminal 1, and the “digital watermark decoding processing unit” is converted from the image data to the magazine. ID and rotation angle are extracted.

At this time, if either the magazine ID or the rotation angle cannot be extracted, the following procedure is executed.
The “digital watermark processing unit” of the portable information terminal system processing unit 10 causes the screen display unit 18 to display message information such as “please shoot again”. Next, the above-described shooting button is displayed again on the screen display unit 18, and the subsequent procedure is repeated from step S05 shown in FIG.

  On the other hand, if both the magazine ID and the rotation angle can be extracted in step S06, step S07 and subsequent steps are executed.

  In step S09, when the operation key 17 corresponding to the transmission button is operated, the “data transmission processing unit” of the portable information terminal system processing unit 10 is buffered in the image memory in addition to the input e-mail address. The received image data and the magazine ID and rotation angle extracted by the “digital watermark decoding processing unit” are transmitted to the server 100.

  In step S 10, the e-mail address, image data, magazine ID, and rotation angle transmitted to the server 100 are received by the “data reception processing unit” of the digital watermark processing unit 23. In the third embodiment, it is not necessary to check whether the magazine ID and the rotation angle can be extracted at this stage. Therefore, in the third embodiment, step S13 and subsequent steps are executed subsequent to step S10.

Next, about the pattern 2 (2nd Embodiment) shown by FIG. 9, FIG. 10, the one part step is deform | transformed as follows.
In step S106 of FIG. 9, when the operation key 17 corresponding to the shooting button is operated, the image shooting processing unit 13 activates the camera of the portable information terminal 1 to shoot the application stub F in which the serial number has been entered. . When the application stub F is photographed, the generated image data is temporarily buffered in the image memory built in the portable information terminal 1, and the “digital watermark decoding processing unit” is converted from the image data to the magazine. ID and rotation angle are extracted.

At this time, if either the magazine ID or the rotation angle cannot be extracted, the following procedure is executed.
First, the “digital watermark processing unit” of the portable information terminal system processing unit 10 displays message information such as “please shoot again” on the screen display unit 18. Next, the above-described shooting button is displayed again on the screen display unit 18, and the subsequent procedure is repeated from step S105 shown in FIG.

  On the other hand, if both the magazine ID and the rotation angle can be extracted in step S106, step S107 and subsequent steps are executed.

  Next, in step S109, when the operation key 17 corresponding to the transmission button is operated, the “data transmission processing unit” of the portable information terminal system processing unit 10 displays “digital watermark” together with the image data buffered in the image memory. The magazine ID and rotation angle extracted by the “decoding processing unit” are transmitted to the server 100.

  In step S 110, the image data, magazine ID, and rotation angle transmitted to the server 100 are received by the “data reception processing unit” of the digital watermark processing unit 23. Here, similarly, it is not necessary to confirm whether or not the magazine ID and the rotation angle can be extracted. Therefore, step S113 and subsequent steps are executed following step S110.

  Even when the electronic lottery method of the third embodiment is adopted, as in the first and second embodiments, application by a person other than the magazine purchaser, or by the same person or multiple persons using the same application ticket Needless to say, duplicate applications can be eliminated.

  In the third embodiment, only one of the magazine ID and the rotation angle is extracted by the digital watermark decoding processing unit of the portable information terminal system processing unit 10, and the remaining one is the same as in the first and second embodiments. The digital watermark processing unit 23 of the server system processing unit 20 can also perform extraction.

(1) Transfer / rental measures for application stubs As a general rule, the lottery execution body that hosts the lottery must not transfer or rent application stubs used by the magazine purchaser for present application (registration) to others. Call as a rule.

  If the application ticket or application stub actually passes from the magazine purchaser to the other person's hand, and if the application ticket or application stub is unused, the other person who receives it first will use it for the first application. As preferred. On the other hand, when the magazine buyer himself / herself passes the used application stub to another person, even if the other person who receives the application uses it for the application later, the magazine purchase used first for the image data of the same application stub Is given priority as a first-come-first-served basis. This is because, when application data having the same image feature amount is selected within the winning range, priority is determined in the order of registration. In this way, for multiple applications using one application stub, only the first one is valid, so duplicate applications by the same person or multiple persons using one application stub are automatically To be eliminated.

  Furthermore, since it is determined that the application stub is filled with a serial number and photographed, even if a plurality of application data using the same application stub remains up to provisional winning, the winning determination processing unit 35 determines the serial number. When duplication is confirmed, it is possible to exclude other than the first-come-first-served, or all but the first-come are excluded. If all items are not selected, the magazine purchaser may not be selected, but in this case, the magazine purchaser will transfer the application stub to another person or avoid the risk that he / she will not be selected. It is expected that there will be no lending or duplicate application.

  As described above, a mechanism has been established to eliminate duplicate applications using the same application stub in the electronic lottery system, but when another person who receives this application further tears down the application stub and changes its shape The following measures are effective.

(2) Reuse measures by transforming a used application stub First, if the application stub that has been torn once is further torn, the area will be reduced accordingly, so the area ratio of the original application ticket will be much less than 50%. it is conceivable that. In this case, the effective area of the digital watermark is insufficient, and the magazine ID may not be completely extracted therefrom. If the magazine ID is not extracted, it is not registered as application data as described above, and as a result, applications by others are excluded.

  When another person further tears down the application stub, if the area ratio does not fall significantly below 50%, the magazine ID may be extracted and registered as application data. In this way, when the used application stub is deformed, the torn shape (the shape of the broken line) changes compared to the previous one, and the image feature amount is not common. For this reason, if the image feature amount is close to a winning stub, it may remain until a temporary winning. However, since the serial number is entered in the modified application stub again, if the serial number is confirmed to be duplicated, all applications other than the first arrival or all applications are excluded.

  The above measures are effective for all duplicate applications that can currently be envisaged. However, since the application lottery is used in the electronic lottery, it is known that there is always the remaining stub (the area ratio is less than 50%). For such remaining stubs, if the newly acquired serial number is entered and photographed, it may be registered as application data if the area ratio does not fall significantly below 50%.

  The inventors of the present invention have further studied such an assumed case, and as a result, have confirmed that the following measures are effective. For example, if the stubs indicated by the two image data are in the form of a tally, and if the area ratios of both are 100%, these will break one application ticket. It is assumed that there is a relationship between the application stub made and the remaining stubs, and those who have applied later will not be registered as application data. This ensures that duplicate applications using the remaining stubs are eliminated.

  In the first and second embodiments, the winning process is executed after the completion of the predetermined present application period (deadline), but the application data is registered without waiting for the end of the application period. You may decide and notify the lottery immediately on the spot. In this case, a predetermined winning range is determined in advance for the image feature amount of the winning stub, and all the items that have entered the winning range are uniformly won, or on a first-come-first-served basis until a certain winning frame is filled. You can also notify the result as a winner.
