Description

 The invention relates to methods for conducting game processes, in particular to methods for conducting lotteries with the participation of holders of identification cards.

 There is a well-known way of organizing lotteries by issuing issuer-organizer of special identified cards, distributing these cards among purchasers, organizing a draw and providing winning tickets to purchasers to receive the appropriate reward.

 There is a known method of conducting a lottery, which consists in the fact that the organizers of the lottery first issue lottery cards and distribute them among the players, and then, based on the results of the distribution of lottery cards, form a prize pool and draw among the players, as a result of which the winning lottery cards are determined and assigned to them certain sizes of winnings. At the same time, wishing players with winning lottery cards are registered to participate in the following lottery draws without giving out a win, with its subsequent issuance with summing up the winning size of the drawn lottery with winnings in the following draws. Players can purchase lottery cards of any lottery draw. The method of conducting the lottery draw allows you to increase the attractiveness of the lottery by increasing the gaming capabilities and increase its economic efficiency (RU, 2122877, IPC A 63 F 3/08, 1998).

 There is a known method of holding a lottery game, implemented in the Sportloto game and consisting in distributing specially numbered tickets with an information block of data applied to them for drawing them according to a random law at a predetermined time, and in determining and issuing a money or clothing prize (RU, 2023307, IPC G 07 C 15/00).

 There is a known method of conducting a lottery (RU, 2124230, IPC G 07 C 15/00, 1998), where the main drawing process is based on the subsequent and random occurrence of game numbers, computer tracking the coincidence of these numbers with number sets in the game fields of the tickets involved in the drawing , identifying tickets in which the numerical sets coincided with the numbers drawn, the announcement of the numbers of the winning tickets and the size of the winnings.

 The disadvantages of this method of conducting the lottery: the need for special terminals for the sale of lottery tickets, an independent communication channel for transmitting data through the lottery, blocks for preparing and processing documents, complicating and costing the lottery.

 The objective of the invention is to develop a new method of drawing a lottery, in particular, involving owners of identification cards to participate in it, simplifying the procedure for participation and obtaining winnings.

 The problem is solved in that in the method of conducting a lottery, including issuing lottery tickets, generating data on the tickets participating in the drawing, distributing the prize pool, conducting the lottery and paying out the winnings, the lottery is carried out in systems using identification cards. Moreover, lottery tickets are issued in electronic form, for which purpose a set of identification data of electronic lottery tickets is generated in the lottery part, by which the winnings are distributed, for which they are included in the generated set of identification data, and identification cards are used as information carriers about electronic lottery tickets. Data on available identification cards are transmitted to the lottery part and a set of data for the correspondence of electronic lottery ticket numbers and identification card numbers is generated in the lottery part, after which data on identification card numbers corresponding to the winning tickets are transmitted to the places of use of identification cards. When using identification cards, it is determined whether the electronic lottery ticket has a win corresponding to the used identification card, and then, if the electronic lottery ticket is won, the prize is paid at the points of payment. In this case, when forming the data set of correspondence of electronic lottery ticket numbers and identification card numbers, the dependence (n • M + C) mod Т = K is used, where n is the checked number of the electronic lottery ticket, mod is the operation of finding the remainder of division, M, C, T and K are the numbers that make up the set of parameters of the function, while K is any number from 0 to T-1, and T = N / win, where N is the total number of ticket numbers, and win is the required number of winning tickets, and M, C, T are coprime numbers, and M and C are greater than the maximum number from N.

 The problem is also solved due to the fact that the dependence parameters are changed in the lottery part, and then transferred to the place of use of identification cards.

 The problem is also solved due to the fact that all changes to the set of compliance data and dependency parameters are made in the lottery part, and they are transmitted to the places of use of identification cards synchronously.

 A set of data on the correspondence of electronic lottery ticket numbers and identification card numbers can be formed in the lottery part of the lottery so that when using (authorization) identification cards, the determination of compliance with winning lottery tickets is performed using the dependence, which is in general form: W = F (N ; {P}), where F is the correspondence function used in the part authorizing the identification cards, N is the set of identification card numbers, W is the sign of the winning identification arts, {P} - a plurality of matching feature parameters. Dependence parameters W = F (N; {P}) can be changed in the lottery part of the lottery, and then passed to the authentication places of identification cards. Changes to the set of compliance data and the dependency parameters W = F (N; {P}) can be made in the lottery part and transmitted synchronously to the places of authorization of identification cards.

 As data on winning tickets to places of use of identification cards, data can be transmitted on the parameters {P} of the correspondence function, on the basis of which, when authorizing an identification card, identification cards are identified that correspond to winning lottery tickets.

 The lottery begins with the creation of electronic lottery tickets. The entire set of lottery tickets declared in the lottery is stored in the database of the lottery part as a set of records. Each entry contains information about one electronic lottery ticket.

 Next, we construct a table of correspondence of the numbers of ID cards to the numbers of electronic lottery tickets and select the dependence parameters for choosing the winning numbers of electronic lottery tickets.

 Dependence parameters are chosen so that the numbers of identification cards that correspond to the numbers of winning tickets, after applying this function at the time of authorization of identification cards, return the value "true".

 Authorization (use) of identification cards can be made when paying for travel in metro turnstiles, or when paying for a purchase in a store in terminals authorizing credit cards, and in any other payment systems using identification cards. In all cases, from the authorization device (turnstile, terminal, etc.), which is an integral part of such a payment system, with the possibility of accessing a centralized computerized system for information about the identification card. To conduct a lottery, the indicated dependence may be included in a payment system using identification cards, and after authorization, this payment system transfers information about the authorized card to the lottery part. Information between the payment system and the lottery part can be transmitted through computer networks connecting these systems.

The dependence W = F (N; {P}) should be represented in the following form: (n • M + C) mod T = K, where n is the checked ticket number, mod is the operation of finding the remainder of division, the symbols M, C, T and K - constitute the set of parameters {P} and denote the numbers that make up the set of parameters of the function. The winning number is the number for which this function gives the value W = "true". In order for this function to satisfy the above requirements, the following restrictions are imposed on its parameters:
all parameters are positive integers;
M, C and T - should be coprime numbers (then the factors available in the input number n will not affect the result of the calculations);
M and C - must be greater than the maximum value of a number from N (then the calculations will ensure the "mixing" of numbers before checking);
the numerical representation of the numbers M and C should not be regular. To ensure good “mixing”, the signs forming the numbers M and C must themselves be mixed. For example, 100001 or 7979797 should not be used. An example of a successful number is 31415923;
K - can be any number from 0 to T-1 (since the remainder from dividing any number by T is in this range);
the value of the parameter T is chosen in such a way as to provide the required number of winning numbers: T = N / win, where N is the total number of ticket numbers, and win is the required number of winning tickets.

Example
An example is built under the following real conditions of functioning of the authorizing part (St. Petersburg Metro):
- ID cards are subway tickets based on plastic cards with a magnetic strip (magnetic cards - MK);
- authorization is made in the turnstiles of the lobby of the subway;
Metro payment systems include, in addition to turnstiles, cash registers and the metro information and computing center connected by computer networks;
magnetic cards participating in the lottery are withdrawn from circulation upon authorization until the next day of work;
there is a significant time interval for system recovery after a working day until the next, when the authorizing part is not functioning.

 Under these conditions, it is possible to build a lottery implementation with discrete moments of data preparation and exchange between the lottery and the authorizing part: at night intervals between working days of the authorizing system. At these points in time, data is exchanged between the authorizing part of the subway and the lottery part. During the working day, both systems function independently.

 In the turnstiles of the subway there is a functional unit that implements the calculation of the dependence W = F (N; {P}): f (n), and many parameters {P} are loaded into the turnstiles at the moments of information exchange before the beginning of the working day of the subway.

 The Instant Lottery begins with the creation of electronic lottery tickets. The entire set of lottery tickets declared in the lottery is stored in the database of the drawing machine in the form of records. Each entry contains information about one lottery ticket, thus making up the “Tickets” table. In our example, the table contains information about 10 tickets - this is the entire set declared in the "approximate" lottery.

 Here is the initial state of the entries in this table.

Day 0. The instant lottery begins with the creation of electronic lottery tickets. The entire set of lottery tickets declared in the lottery is stored in the database of the drawing machine in the form of records. Each entry contains information about one lottery ticket. Instead of writing about lottery tickets, make up the Tickets table. In our example, the table contains information about 10 tickets - this is the entire set declared in the "approximate" lottery. The initial state of the records is presented in table. 1
At the same time, there are 5 MKs in circulation, data on which are also entered into the database of the circulation machine (Map tables). The initial state of the table is presented in table. 2
Day 1. The table of correspondence of MK numbers to the numbers of lottery tickets is constructed and the parameters of the MK selection function for the winning numbers of lottery tickets are selected. The column with card numbers should contain all possible card numbers. The second column of the correspondence table is filled in with the numbers of electronic lottery tickets from the Tickets table in random order. The initial state of entries in the Compliance table is as follows:
N cards - N tickets
0 - 0
eleven
2 - 2
3 - 3
4 - 4
Among the currently selected lottery ticket numbers in the second column of the Matching table, the winning ticket is ticket number 1 (with an amount of 100 rubles, according to the Tickets table).

 The parameters of the selection function are selected in such a way that the MK numbers, which correspond to the numbers of the winning tickets, after processing this function turn into the value "true". Parameter T - directly calculate T = 5 (i.e. 5/1), choose M = 7 and C = 3. It remains to choose K so that for the winning MK (now it is MK with number n = 1), the value of the expression (n • 7 + 3) mod5 = K is true. Here is a way to find such K. Let us calculate the values of the expression on the left side of the comparison operation for all n and place them in the table. 3.

 If now we choose the value of the parameter K equal to 0, then the calculation of the winning number selection function implemented in the subway turnstiles will give the value “true” for MK with number 1 (see the third column in the table).

 Before the underground starts, the values of the parameters T, M, C and K determined in this way are transmitted through communication channels to all the subway turnstiles. During the working day of the subway, presenting the magnetic card with number 1 to the turnstile will cause the subroutine f (1) to be called, which will return the value “true”, and the card will be recognized by the payment system as the winning one. The passenger, the holder of this card, can not only drive in the subway, but also get a win at the ticket office.

 End of day 1. On the next day of work (and all subsequent days), when constructing a correspondence table and selecting parameters of a selection function, it is necessary to take into account that some of the cards are withdrawn from circulation and the numbers of lottery tickets used are no longer involved in the construction of correspondence.

 Let now, after the first day of the lottery, it became known which of the MKs in circulation were sold and which were used. These data, first of all, are reflected in the Map table, where sold and used are marked. At the end of the first day of the draw, the state of the table is presented in table. 4.

 Using the current table of Compliance, we make the necessary changes to the table of electronic lottery tickets: used tickets are deleted from the table, and the winning ones are transferred to the table of winning numbers. The new state of the Tickets table is presented in Table. 5.

 After these changes to the Tickets table in the Cards table, the used cards are ready for use again. The new state in the Map table is presented in Table. 6.

 Thus, we are ready to build the correspondence of numbers the next day.

Day 2. New state of entries in the Compliance table
N cards - N tickets
0 - 2
fourteen
2 - 5
3 - 6
4 - 7
In the right column there are again the five first available numbers from the lottery ticket table.

 The parameters of the selection function should now be chosen so that MK with number 2 turns out to be the winning one, since it corresponds to the winning lottery ticket N 5. Repeating the calculation of the expression (n • 7 + 3) mod5 (see Table 7), we find that K = 2. It is with this value of K that the winning card selection routine will return true. The newly defined parameters T = 5, M = 7, C = 3, and K = 2 will be loaded into the subway turnstiles before the next working day to select MK with number 5 as the winning one during the working day.

 The achieved result when using this invention provides the possibility of attracting ID card holders to the lottery, the safety and anonymity of lottery participants, as well as the elimination of fake lottery tickets and lottery results, the versatility of using lotteries in various circulation systems and authorization of identification cards, saving money on lotteries; lack of restrictions on the size of the lottery ticket circulation.
