Description

An automated and verifiable drawing system and method

The present invention relates to an automated and verifiable lottery system and method thereof, and in particular, to a user in advance a lottery method for determining a winning number on a computer network, such as the Internet, to provide information on the lottery progress and the likelihood and conditions of the lottery The present invention relates to an automated and verifiable lottery system and method for inducing a user's interest, determining a winning number at the same time, automatically notifying the winner, and allowing the user to easily verify the accuracy of the procedure and result. .

The Internet is a huge network of information, accessed by tens of millions of users every day for information, and tens of thousands of websites competing. Websites use a variety of methods such as free service, competitions, and giveaways to attract more members and attract access, but among them, prizes or giveaways to a small number of winners are widely used. . However, the vast majority of Internet users are skeptical that the prizes promised at the event are really offered, the winner draws are fair, and the odds of winning the prize.

Taking the fairness of the lottery as an example, the event organizer stated that the lottery method uses random sampling using a random number generator, but it is difficult to find users who trust it completely. Although the lottery system suggests a method for determining the winner, the process cannot be disclosed in detail, causing users to doubt, and such doubt has been a factor that hinders the desire for use and participation.

The most transparent and open way of the lottery methods currently in use is to use variable, uncontrollable clues, such as a certain number of users (eg 10,000 subscribers) or stock quotes. A variable number (e.g., stock price information, lottery winning numbers, weather information, number of subscribers, etc.) determined at a certain point in the future is used to identify a user's identification number (e.g. Rewards users who match or are closest to the number given. Although this method is relatively more transparent, there are no or very limited areas where users can participate during the event, and it is difficult to attract users' attention and interest because it cannot guarantee fairness and transparency.

The present invention was devised to solve the above problems, and an object of the present invention is to develop a lottery method on a computer network such as a simple internet that anyone can understand, and to disclose it to applicants before or at the beginning of the lottery. To provide an automated and verifiable lottery system and method thereof.

Another object of the present invention is to give the applicant a series of application numbers at the same time, to check the progress of the sweepstakes from time to time, while allowing the applicant to look up the possibility of winning and the conditions of the entry number To provide an automated and verifiable lottery system and method for enhancing interest and participation in the event itself.

Another object of the present invention is an automated and verifiable lottery system and method for allowing the lottery result to be automatically notified to the winner at the end of the event, and the applicant can easily verify the fairness of the procedure and the accuracy of the result. To provide.

First, a lottery method that anyone can understand is established by reducing the number of reference numbers used and making the operation easy and simple. For example, if only the total number of applicants until the end of the lottery is determined by the variable standard, the winner is decided and the remaining winners are automatically determined according to the number of prizes. Will be.

Then, how to increase the interest and participation of participants in the event can be used to draw clues that automatically occur at a particular event, and to convince the candidate that the results can be influenced by the way they influence the clues. It becomes possible. More specifically, under what circumstances the event will end, e.g. how many participants will be in a timed event with a deadline, and how many minutes / second will be required for a limited time event with a limited number of entries. Accreditation is the only clue to determine the winner, and if the applicant thinks he can influence the decision, the interest and interest will increase significantly. When contestants think that they can't, but it's possible, they will have the attributes of a game in which they actively watch the final clue's decision making process.

Furthermore, if the result of the lottery determined according to the pre-determined rules at the end of the event is output from the winner's database and automatically notified, the event operator does not need to perform a separate lottery. The advantage is that you can see and be notified of the results.

If the result of the draw is notified, the entrant or organizer may immediately verify that the draw has been carried out according to previously published rules. In other words, if a simple arithmetic calculation that anyone can understand can be examined through a PC or a lottery server calculator, the applicant will be sure of the transparency and fairness of the lottery procedure.

In order to achieve the above object, a lottery system according to the present invention includes a plurality of clients in which identification information is registered for each member; A lottery server that discloses a lottery method to applicants in detail and provides a lottery number determined according to the lottery method in real time; And a computer network, such as the Internet, that can access the lottery server to the plurality of clients.

In addition, other applicants may watch their own advertisement of the lottery server, and other websites may use the lottery service provided by the lottery server to attract the lottery conspirators.

The lottery method according to the present invention comprises the steps of: receiving identification information from a user and logging in; Storing the identification information in a contestant database and assigning a sequential contest number; Disclosing the drawing method to the applicant in detail; Database lottery results in a published manner in advance; Converting the expected winning number database into the applicant's center so that the applicants can inquire in advance; Determining a winner by drawing a draw according to a publicly disclosed lottery method after the deadline; And automatically notifying the winner of the winning result.

The lottery method of the present invention begins by selecting one of the reference numbers (e.g., the number of applicants) generated during the event and applying a simple arithmetic operation (e.g., division or square root) to determine the first winner. For example, if you choose the total number of applicants (and total time required) for the first winner draw and use the square root for arithmetic operations, first find the square root of the total number of applicants and use the fractional part of the value as the reference number. Determining; Determining an entry number (integer) closest to a value multiplied by the reference number and the total number of entries as a first winning number; Dividing the value by the number of prizes promised to provide the total number of applicants; And determining the remaining winning number by adding or subtracting the interval between the first winning number as many times as the number of remaining prizes.

An embodiment of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the configuration of one embodiment of a lottery system according to the present invention.

The lottery system of FIG. 1 includes a plurality of clients 11-1, 11-2, ..., 11-n in which identification information is registered for each member; A lottery server 13 that discloses a lottery method in detail and provides a winning number determined according to the lottery method in real time; Organizer website (15).

In FIG. 1, a plurality of websites 14-1, 14-2,..., 14-n display a sweepstake advertisement requested by the sweepstakes organizer 15, and a plurality of clients 11-11. 1, 11-2, ..., 11-n) access one of a number of websites 14-1, 14-2, ..., 14-n to watch the advertisement and enter the raffle . The Internet 12 includes the plurality of clients 11-1, 11-2, ..., 11-n, a plurality of websites 14-1, 14-2, ..., 14-n, organizers The website 15 and the lottery server 13 are provided with a computer network which can communicate at any location in the world.

The lottery server 13 is a database of expected winning numbers created according to a lottery method previously published on the websites 14-1, 14-2, ..., 14-n or the organizer site 15 where the prize event advertisements are displayed. It also has a database of winning and condition checks and a verification calculator.

The organizer site 15 is a site of an organizer that provides a sweepstakes, and an advertisement is displayed on the plurality of websites 14-1, 14-2, ..., 14-n.

2 is a block diagram showing the internal configuration of the lottery server 13 of FIG.

The lottery server 13 according to the present invention is a lottery method that specifically discloses a lottery method determined according to the entrant database 21 and the lottery event in which various information related to the applicant's subscription, access, application, etc., and the application number are entered. The disclosure means 22; Automatic lottery means 23 for performing a lottery in accordance with the public lottery method; A database 24 for storing a preliminary number of winnings calculated for the number of possible cases using the lottery method disclosure means 22 and the automatic lottery means 23; Inquiry means (25) for inquiring about the possibility of winning and the conditions in advance; Automatic notification means (26) for automatically notifying the winner of the winning result when the drawing is finished; Verification means (27) provided so that the applicant can reproduce whether the drawing has been performed according to the disclosed drawing method; Central processing means (28) for controlling the respective parts; It consists of.

The entrant database 21 inputs various information related to an event such as subscription, connection, entry, etc. of the entrant, and is used for communication such as lottery server 13 connection of the entrant, notification and inquiry of the lottery result.

The lottery method disclosure means 22 discloses the lottery method determined in advance by the organizer website 15. For example, an event (time-limited) that seeks to engage as many users as possible within a limited period of time may use the total number of entries as a criterion for the draw. On a first-come, first-served event (e.g., a limited number of participants, including 10,000 survey participants), other event-related information (total time to close) may be available. Give specific details on how to draw.

3 is a flow chart showing how the lottery server 13 of FIG. 1 determines a winning number.

The drawing method executed by the drawing server 13 is a step in which a client (for example, 11-2) accesses the organizer website 15, enters identification information (ID and password, etc.), logs in, and receives an application number. (S31); Receiving the identification information and the application number from the organizer website (15) and storing it in the applicant database (21) (S32); In the step 33 of closing the lottery application and the automatic lottery means 23, the standard number is selected according to the lottery method disclosed in the lottery method disclosure means 22 (for example, the square root of the number of applicants is obtained and the value below the decimal point is calculated. Adopting), determining a winning number closest to the value obtained by multiplying this value by the total number of applicants (S34); Dividing the total number of applicants by the total number of winners to obtain an interval (S35); And determining the remaining winning number by adding or subtracting the interval to the first winning number (S36).

The automatic lottery means 23 generates the lottery result for all possible cases in advance. For example, in a time-limited event in which 1st and 1st 10 students are selected, the number of applicants is selected as the standard number for drawing, the square root is used as an arithmetic means for extraction, and the remaining winners are decided after determining the first winner. Suppose that systematic extraction is made in the lottery method disclosure means (22). At this time, the automatic lottery means 23 obtains the square root of the total number of applicants, and the entry number closest to the value multiplied by the value below the decimal point and the total number of applicants is the first winner, and the other winner numbers are the total winners. The principle is to add or subtract by dividing the number by the number and to calculate the expected winning number for all possible numbers. For example, even if the total number of applicants is expected to be less than 30,000, the results are published according to published rules for even more cases, ie all possible conditions from 1 to 100,000. This result is stored in the winning winning number database 24.

4 is an example of such an example, in which the winners are calculated in advance when the total number of applicants ends with 2341 to 2350, 10,000, and 100,000 in an event where the first and second persons are ten. The winning number database (24) created according to the lottery rule which takes the area below the decimal point of the square root and multiplies the value by the total number of applicants, and then extracts the total number of entries divided by the number of prizes. Is an example of a winning number.

Arithmetic manipulations on selected clues can vary. You can select one constant and manipulate it at the same time, you can use any of the four arithmetic operations, and there's no reason to be in the first decimal place. The important thing is whether the result of this arithmetic operation guarantees the randomness. The work was done to determine whether the square root value of the total number of applicants (or total time required) had a characteristic of random number, because the value of the sub-dot area was not biased, which gave almost equal winning probability to all the applicants. After finding the square root of 100,000 values from 1 to 100,000, we took only the decimal point area and rounded it to three decimal places to make 100 categories (0.00 to 0.99) with two decimal places and confirmed the distribution on each. The results showed that the minimum of 100 categories ranged from .13 and .88 (967 cases / 0.967%) to the maximum range of .87 (1037 cases / 1.037%) under the expected frequency of 1,000 cases and the expected composition ratio of 1.000%. FIG. 5 shows that the distribution of values below the decimal point of the square root has sufficiently the characteristics of the random number path.

As an example of applying the other arithmetic operation, we tried to verify the radioness by selecting a large prime number as a constant and dividing it by the total number of applicants (total time required). In this example, the distribution of values below the decimal point was selected among M31 of the Mersenne prime, that is, 2 ³¹ -1 value (2,147,483,647) and divided by the number of applicants from 1 to 100,000. This result is not as small as the square root, but at least 899 cases (category .87), the maximum 1207 cases (category .00) can be seen from Figure 6 has the characteristics as a random number.

When the first winning number is determined in a probabilistically fair manner no matter what method is taken, the first winning number is continuously added to or subtracted from the total number of entries divided by the total number of prizes. If the total number of applicants is exceeded, the total number of applicants will be selected and the number of winners will be continued until the total number of winners is obtained. All prizes must of course be given a serial number.

The automatic lottery means 23 calculates the winning number as many as the number of winners for all possible cases as described above, and when the winning estimated number database 24 is constructed as shown in FIG. 4, this database centered on the total number of applicants Further create a database 25 for providing a pre-search means reconstructed around the individual application number. That is, the expected winning number database 24 shows how many times and how many prizes are won when the total number of applicants, while the database 25 for providing a pre-inquiry means reconstructed the number of the total number of applicants At the end of a few students, show that you will win some prize. Fig. 7 shows only 10 cases in which the applicant with the entry number 234 or the entry number 2340 can win the prize when the number of the applicants is the total number of entries after the entry. It is the basis of the database 25 for providing the inquiry means. This is automatically rearranged upon preliminary inquiry of the winning conditions, and presented in the form of the winning conditions 117 of FIG. 11, and when the number of applicants increases, it is automatically updated at the time of inquiry to present only a larger number of entries.

When the event is closed, the total number of applicants will be determined (time-limited event), and the automatic notification means 26 will take out the result corresponding to the confirmed total number of winners from the winning number database 24 and automatically notify all winners and automatic notifications. To the candidates (11-1, 11-2, ..., 11-n) and the prize organizer (15) and the ad serving website (14-1, 14-2, ..., 14-n). You will be notified by e-mail. This process can eliminate the deadline for applicants, waiting for the lottery to be completed, and the burden of the lottery's work.

As soon as the final result is notified, the entrant and all interested parties can directly verify using the verification means 27 whether the lottery procedure and the results were performed fairly and accurately as presented in the lottery method disclosure means 22. A detailed description of the verification is provided later.

Many websites 14-1, 14-2, ..., 14-n use the Internet 12 to perform various business. Sweepstakes organizers place advertisements for sweepstakes and the like on a number of websites 14-1, 14-2, ..., 14-n for their business. A number of websites 14-1, 14-2, ..., 14-n provide web screens for their own tasks to clients (eg, 11-2) who have accessed the web screens. As shown in FIG. 8, a part of provides a banner advertisement informing of an event.

8 illustrates an example in which a sweepstakes advertisement is displayed on a screen provided by a website.

Advertisement of a sweepstake on a portion of the screen 81 provided by one of the websites 14-1, 14-2, ..., 14-n (e.g., 14-2). 82 is displayed. Inside the advertisement 82 is provided an AVD link 83, which symbolizes how the prize draw will proceed, indicating that the AVD is an " Automatic and Verifiable Drawing System. &Quot; Therefore, Internet users will participate more actively if the prize is marked with an AVD, the lottery method will be disclosed, the possibility of winning and the preliminary inquiry of the conditions, the result will be automatically notified and the verifiable method.

When the client 11-2 who accesses the website 14-2 providing the giveaway advertisement 82 clicks on the advertisement link 82, the client 11-2 is connected to the giveaway site 15 and the AVD link 83 Click to link to the AVD website (FIG. 10). The client 11-2 connected to the giveaway site 15 receives the screen as shown in FIG. 9.

9 illustrates an example of a sweepstakes screen provided by the sweepstakes organizer site 15 of FIG. 1.

The sweepstakes event screen 91 includes a sweepstakes content display area 92 for displaying an event period of the organizer, contents of the sweepstakes, and the like; A link 95 for selecting an application; An entry number display area 93 for displaying an entry number assigned to the applicant; And a lottery method disclosure area 94 for displaying the manner in which the prize is drawn at the prize event.

In the prize event contents display area 92, contents such as an event period, the number and type of prizes to be provided, a lottery method, and a notification method are displayed. The application number display unit 93 displays an application number automatically assigned when the application display unit 95 is clicked after the application is completed. This entry number is sequential so there can be no missing number in the middle, and it cannot be given in duplicate. In the AVD drawing method application area 94, the drawing method of the sweepstakes event is displayed. In other words, the details of the lottery event will be disclosed in detail, the possibility of winning the prizes and conditions can be inquired, and the lottery and winner notification will be automatically performed and the procedure and results can be verified. Inform the lottery that it is transparent.

The lottery server 13 may be a client 11-2 who clicks the application link 95, a client 11-2 who clicks the AVD link 83, or a client 11 who clicks the AVD draw method application link 94. -2), a screen for explaining the drawing method in detail is provided as shown in FIG.

FIG. 10 is a description screen of a lottery method provided by the lottery server 13 of FIG. 1.

The lottery method description screen 101 includes a prize contents display area 102 for displaying contents of prize periods and prize items; A lottery method description area 103 for explaining the lottery method; A pre-inquiry link 104 for inquiring about the progress of the sweepstakes and the possible winnings and conditions; And the result of the lottery automatic notification link 105, and the procedure and result verification link 106.

The lottery method description area 103 displays the winner lottery method in a manner that is easy for anyone to understand. For example, the 1st draw method displays “Determine the first entry number closest to the value multiplied by the number below the decimal point and the total number of applicants among the square root of the total number of applicants to be confirmed at the same time as the deadline,” and the second prize. , 3rd place or less lottery means "divide the total number of entries by the number of prizes (for example, 11), and continue to divide the value 10 times from the 1st number (the total number of prizes minus" 1 ") Subtracted value ". And as an example of them, the total number of applicants: 157,325, the square root value: 396.642156105 ..., the fractional value of the square root: 0.642156105 ..., the product of the square root and the total number of applicants: 101027.209219 ..., 1st place The number 101,027 is displayed. As an example of a winning number below 2nd place, the grade (number of prizes divided by the total number of entries): 14302.27272 ..., the example which adds 2nd grade, 3rd grade, ... in order by adding grade to said 1st number is shown.

Disclosure of the lottery method will be described in a manner that is easy for anyone to understand, as described in the lottery method disclosure area 103, but in this manner, the first prize is one of the clues that occur at the end of the event, and the second prize is below. Shows that everything is determined by the number of. This simplicity may cause doubts about the operability, but there is no problem because the clues, such as total number of entries or total time required, cannot be manipulated by someone's will. Rather, they can make an effort to influence them, leading to more active participation.

When the applicant clicks on the winning possibility and condition inquiry link 105, a screen for inquiring the current progress, the winning possibility and the condition is provided as shown in FIG. 11.

The winning possibility and condition inquiry screen 111 displays a deadline for the time when the time limit type, and a deadline / person display area 112 for displaying the deadline when the number of people is limited; A number of contestants display area 113 for displaying the number of contestants so far; An entry number display area 114 for displaying an entry number; A winning probability displaying area 115 which displays a winning probability; A current winning number display area 116 for displaying a current winning number; And a winning condition display area 117 for displaying the winning condition; and a verification link 118 for verifying the winning number.

The most important element in FIG. 11 is the win condition condition display area 117. This area reconstructs the winning expected number database 24, which is organized in the order of application numbers, around each of the application numbers, so that the applicant can search for his / her chance of winning. Winning condition inquiry (117) shows the results that can be provided when the entry number 234 is the first prize winner 1, 2nd prize 10 winners in the event of winning the prize immediately after entry. This is a summary based on the application number that you want to inquire. As the number of entries increases, this result is automatically updated.

This preliminary inquiry function has the intention of inviting participants to influence the outcome of the lottery, which can attract more attention and participation of more and more people later in the event. Of course, it will be more effective if you plan your event so that one applicant has two or more entries.

When the lottery clues, ie the total number of applicants or the total time required, are determined at the same time as the deadline, the automatic notification means 26 clicks on the automatic notification 105 of the result of the lottery and sends the winning client number 11-2 to the desired client 11-2. Among the contents of the lottery clues, that is, the final lottery results are taken out and connected to the applicant database 21 and notified through the Internet 12, and the event advertisement sites 14-1, 14-2,. .., 14-n) and organizer site (15).

After the result of the lottery is automatically notified, anyone who clicks the verification link 106 or 118 is displayed a verification screen 121 that can verify the accuracy of the result as shown in FIG.

The verification screen 121 may be used at any time during and after the event and includes a total number of applicants displaying area 122 displaying the total number of applicants up to now; A square root display area (123) for displaying an arithmetic operation (e.g., square root) on the total number of applicants; A first number display area 124 for displaying a current first winning number; An intermittent display area 125 configured to display a value obtained by dividing the total number of applicants by the number of prizes at an interval; A winning number display area 126 for displaying a winning number of 2 or less; A calculator area 127 for calculating the number displayed on each display area; And a drawing method description area 128 for explaining the drawing method.

The content displayed on the verification screen 121 may be calculated by using the calculator area 127 to verify the applicant. The calculator can use the built-in calculator (32 digits) in MS Windows or input a separate one.

The embodiment of the present invention described above is one of the examples in which the present invention is applied, and various modifications and improvements are possible without departing from the technical spirit of the present invention.
