Description

THE METHOD AND SYSTEM FOR REALIZATION OF A PAID PUBLIC ACTION USING A TERMINAL UNIT OF PLAYER AND A REGISTRATION SERVER UNIT.
FIELD OF THE INVENTION
The present invention relates to realization of lottery /totalizator games systems and methods. BACKGROUND OF THE INVENTION
The present invention relates generally to remote gaming systems, and more particularly, to an off-line system for playing games of chance, including instant-type lotteries typically embodied in a ticket having multiple chances which represent a single predetermined outcome offered by a managing authority are rendered on a gaming computer as an "electronic ticket," such as, for example, a dedicated hand-held device or personal computer. In addition, the present invention enables playing games of skill on such a device. In a lottery application, the system enables a player to play instant-type tickets on the game-computer with the same convenience as typical paper scratch-off tickets at any location without the gaming computer ever having to be physically or electronically connected to a lottery system during play, thereby providing enhanced play value for the player and greater profit for the managing authority.
In the case of typical paper instant tickets, a computer generates a randomized prize data stream comprised of a finite series of win/lose outcomes. Each outcome is assigned to a lottery ticket, and each ticket contains one or more chances which yield the assigned outcome. The player cannot change the ticket outcome, he or she merely scratches off certain areas of the ticket in accordance with the rules of the game to reveal the outcome. The ticket contains information which provides the player with a means to determine win/lose results or prize status, and the type of prize (e.g., cash or a free ticket). The aggregate of all winning outcomes in any randomized prize data stream is a predetermined percent of the total revenues that would be generated by the sale of all of the tickets incorporating that particular randomized prize data stream.
As an alternative to instant paper tickets, systems have been devised which replicate instant tickets on a computer terminal or gaming machine. An example is shown in U.S. Pat. No. 5,324,035, which discloses an on-line video gaming system comprised of a plurality of terminals, a number of master processing units, and a central game processor. A plurality of terminals is networked to each master processing unit and all of the master processing units are networked to the central game processor. The central game processor downloads fixed pools of game plays to each master processing unit. The terminals request game plays from the fixed pool in the master processing unit. The group of terminals coupled to a particular master processing unit display indications of the chances of purchasing one of the remaining winning plays in that pool to provide an element of competition between players situated at the various terminals. Thus, players at each terminal may decide to wait for the odds of purchasing a winning play to increase by allowing other competitors to purchase some of the remaining non-winning plays. Although this system is capable of rendering instant paper tickets in a video format, its primary drawback is that it is an on-line system. Every play (outcome) requested by the terminal must be is downloaded on-line from the master processing unit. Accordingly, this system is limited in that players can only engage in lottery play at specified locations.
Another on-line video gaming system is disclosed in U.S. Pat. No. 4,652,998. This system comprises a plurality of terminals networked to a central controller which generates a prize pool based upon a pool seed which is fed to a random number generator. The central controller divides the prize pool into mini-pools, each of which has a known amount of low-end prize value (e.g., all prizes of $25 or less). There are a selected number of larger prizes which are distributed among the mini-pools where some mini-pools have a large prize and some have none. Mini-pools are assigned to each remote terminal for each game which is rendered on the terminal as needed. The remote terminals have means for randomizing each mini-pool assigned to the terminal using a mini-pool seed provided by the central controller to feed a random number generator using a randomizing algorithm. When the central processor has assigned all the mini -pools within a pool, the central processor creates a new pool. After players have played a sufficient number of games to exhaust an entire mini-pool at a given terminal, it connects to the central controller and is assigned a new mini-pool. This system also has limitations. Because the prize structure in the mini-pools is assigned to each remote terminal in a "dynamic state", i.e., the remote terminal is assigned active outcomes before a player engages in play, it is necessary to provide various security measures in the remote terminals to prevent an malicious player from hacking the machine and determining the outcome sequence in any given mini-pool. Otherwise, a player might learn at what point in the mini-pool a large win will occur for the game being played and then wait to play until when a favorable outcome is due to occur. This characteristic renders such a system vulnerable to hacking since a player could conceivably view the outcomes stored in the device prior to purchase. SUMMARY OF THE INVENTION
The present invention is dedicated for the conduction of lotteries and totalizators, using "electronic lottery tickets" offline. It can be used for any type of lottery, including "scratch- off lotteries of complex nature.
Assume, for example, a "prize field" of 49 squares. 6 are colored red, others are colored white. The field is covered with a scratch-off coating, which can be scratched off specific squares individually. The player is required to uncover exactly 6 fields. The prize amount is according to the number of red field discovered (2 - $2, 3 - $50, 4 - $1 ,000, 5 - $10,000, 6 - $100,000). The present invention allows the implementation of such a game electronically. The player buys an electronic lottery ticket. The indices of the 6 red-colored squares are printed on the ticked in an encrypted way. The proposed method of encryption is, on the one hand, virtually unbreakable (it will take billions of years to break the cipher), and on the other hand, enables the player to verify the winning combinations against the ticket itself. The way to do so is made public by the lottery organizer in advance of the lottery itself. The proposed method of encryption is one-to-one, in the respect that there is only one winning combinations for a specific lottery ticket. Thus, the player, after submitting his combinations and receiving an answer from the organizers, can safely and securely and independently check the received winning combinations against the ticket he has. The proposed method of encryption makes it impossible to forge a winning lottery ticket (because they need billions of years to break the cipher). The proposed method of organizing lotteries and totalisatiors can be used to transform all the currently existent paper-based lotteries into electronic form. The reliability and security, both for the organizer and the player, will increase significantly, and the costs shall be significantly reduced due to transformation to paperless form. The number of player will increase because they will not be dependent upon points of sale and registration of tickets, because the individual's own communication means (such as personal computers, mobile devices) can be used.
Another goal of the invention is the ability to accept as payment for game bets: monetary prizes of previous games, monetary prizes of draw/non-draw lotteries and monetary prizes of totalizators. In stimulating lotteries, as a right for making a game bet, it is possible to use the fact of purchase of corresponding goods or services. The choice of such a variant can be performed by the player directly on the individual's own communication means. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
The present invention is intended to give an exemplary description of an implementation. FIG. l depicts a schema of registration server unit (RSU), which performs the following functions. Means 1 receives information (through different networks) from individual terminal units (TU) of lottery/totalizatior players. This information includes identification information, which he uses to identify himself when buying electronic lottery ticket (ELT). This information is transferred either by default (telephone number, logon data, etc), or entered by the player manually (passport number, driver license number and another).
This information also can include data of his choice of guess of the lottery/totalisatior. This information can be either encrypted or in plain text.
Means 2 obtains the registration information for the ELT. This information can be combined from the identification information and the number of active ELTs for the player/TU. Means 3 creates the contents of the ELT by combining the registration information, the identification information and concatenation of the winning combinations and a random/pseudorandom number. The last two pieces are concatenated into a bit string at least 64 bits long. This will be explained later.
The random/pseudorandom numbers are generated by means 4, and the winning combinations are received from chamiel 5. For generating the winning combinations, existent algorithms can be used and are not in the scope of the current invention. Means 6 is used to generate digital signature of this concatenation (here and later, digital signatures will be referred to, but also public-key encryption can be used). For obtaining the digital signature, a private key is used, and for verifying it, a public key. This digital signature is combined with registration information obtained in means 2 and identification information received in means 1. The entire data is the ELT. A digital signature is then obtained for the ELT, and all of it is sent via means 7 to the TU.
The digital signature allows the player to verify the authenticity of the ELT. The procedure allows the player to verify the winning combinations after it has been made known to him.
For draw lotteries and totalisators the process of creating the ELT is simpler. The ELT consists of identification information, received from 1, registration information from 2 and the chosen guess. If the lottery has no guesses, then the last component will not be present. A digital signature is then obtained for the ELT, and all of it sent via means 7 to the TU.
FIG. 2 depicts the schema of the TU (the terminal unit of lottery/totalizator player), which performs the following functions. Means 11 receives information from RSU (the registration server unit). This information comprises: the ELT, the digital signature and elements of protocols described below (see FIG 3 and 4).
Various devices can serve as TU: personal computers, handheld PCs, mobile phones.
If the device is a simple mobile phone, not having means 12 to create a digital signature, then the information about the chosen guess is formulated by the player using means 13-16 and not encrypted. Together with the identification information it is transferred to the RSU via means 17.
If the TU has a means of obtaining digital signature 12, the following procedure is used to encode the ELT: the choice of guess is concatenated with a random/pseudorandom number into a bit string at least 64 bits long. This will be explained later. Means 12 is used to generate digital signature of this bit string using player's private key (the public key of the player is sent to the RSU when player registers for the first time). Then the information is combined with player's identification/registration data and signed with his digital signature. The resulting packet is sent to the RSU using means 17.
By sending just the digital signature of his choice of guess, the player prevents from the RSU to find out his guess, but when he shows the guess to the RSU to collect the prize, the RSU can verify the truth in his claim by using the player's public key.
The concatenation of information with random/pseudorandom data is to ensure the inability of the other side to perform an exhaustive search on all combinations of short size.
FIG. 3 depicts the protocols of interaction between the RSU and the TU. The following symbols are used:
I - the identification information,
N - the registration information,
C - the choice of guess of the lottery /totalizator as chosen by the player,
V - concatenation of the choice of guess with a random/pseudorandom number,
W - concatenation of the winning combinations with a random/pseudorandom number,
D_P - digital signature of player,
D_S - digital signature of lottery/totalizator operator,
D M - digital signature of the mediator.
The digital signature in FIG. 3 and 4 is symbolized by a rectangle, in the lower left corner of which is located the signed information.
FIG. 3a and FIG. 3b depict the protocols of interaction between the RSU and the TU having means 12 for obtaining digital signature.
FIG. 3a depicts a 1 -round protocol of interaction between the RSU and the TU.
1. Player to Server: (Ϊ || D_P (V)) || D_P (I || D_P (V)),
2. Server to Player: W || D_S (W || 1 1| D_P (V)), where "||" stands for concatenation.
Player (1) sends a signed message, containing identification information 1, and his concatenation of the choice of guess with a random/pseudorandom number V. Server (2) sends a message, containing concatenation of the winning combinations with a random/pseudorandom number W, and the player's digital signature of concatenation of the winning combinations with a random/pseudorandom number W, identification information I and the player's digital signature of the choice of guess with a random/pseudorandom number V.
This is the most simple and reliable protocol, where the player only sends the digital signature of his choice of guess. The lottery/totalizator operator cannot find out this choice of guess, he only registers the digital signature and returns the winning combinations to the player. The player can compare the choice of guess with the winning combinations and verify for himself the prize he has won. To collect the prize, the player needs to present the information he has sent (and the information he has received), and document is indicated by the identification information I.
FIG. 3b depicts a 2 -round protocol of interaction between the RSU and the TU.

2. Server to Player: N || 1 1| D_S (W) || D_S (N || 1 1| D_S (W)),
3. Player to Server: (N || D_P (V)) || D_P (N || D P (V)), 4. Server to Player: W || D_S (W || N || D_P (V)).
In the first round, player sends only identification information I, and the server returns registration information N, I and the digital signature of the winning combinations (all these with the digital signature). In this round the player receives the ELT. The second round is similar to the first round (at first protocol), but I is replaced by N. In this protocol the player receives initially the "encrypted" (by digital signature) winning combinations, and only then sends in his choice of guess. A complete imitation of a scratch-off lottery.
In the above-mentioned protocols the player can add the public key of his (or mediator) digital signature to digital signature of the concatenation of the choice of guess with a random/pseudorandom number V and the registration/identification information (N / 1).
For first protocol:
1. Player to Server: (I |) P_ || D_P (V)) || D_P (I || P_K|| D_P (V)),
2. Server to Player: W || D_S (W || N |j PJKjj D_P (V)), where P_ - the public key of the player (or mediator) digital signature.
For second protocol:
3. Player to Server: (N || P_K|| D_P (V)) || D_P (N || P_K|| D_P (V)),
4. Server to Player: W || D_S (W || N || P_K|| D_P (V)), where P_K - the public key of the player (or mediator) digital signature.
FIG. 3c and 3d depict protocols of interaction between the RSU and the TU in cases where TU does not comprise means 12 for obtaining digital signature (for example, simple models of cellular phones).
FIG. 3c depicts a 3 -round protocol of interaction between the RSU and the TU.
1. Player to Server: I,
2. Server to Player: N || 1 1| D_S (W) || D_S (N || 1 1| D_S (W)),
3. Player to Server: N II C,
4. Server to Player: N || C || D_S (N || C),
5. Player to Server: N ]| C || D_S (N )| C),
6. Server to Player: W || D_S (W).
The first round is the same as in the second protocol. In the second round, the player sends only N and C (his choice of guess without the random/pseudorandom number). The server returns the package with his digital signature. In the third round, the player sends back what he received in the second round, and the server returns the winning combinations with his digital signature. The protocol depicted in FIG. 3d is a 2-round version of the previous protocol. It is less secure than the previous. In the second round, the server's answer N || C || D S (N || C) is replaced by
w II II C (I D_S (W II N || C), which includes the answer from the third round of the previous protocol.
FIG. 4 depicts protocols of interaction between the RSU and the TU in cases where TU does not comprise means 12 for obtaining digital signature, but with an independent mediator. They are obtained from the first two protocols by adding one more round between the player and the mediator. In this round, the mediator digitally signs the player's information. The mediator also concatenates C with a random/pseudorandom number.
For the realization of the ability to accept as payment for the game bet (and other types of participation in public actions) of: monetary prizes of previous games, monetary prizes of draw/non-draw lotteries and monetary prizes of totalizators, one can use databases containing winning tickets of draw/non-draw lotteries or databases containing winning bets of totalizators. In stimulating lotteries, as a right for making a game bet, it is possible to use the fact of purchase of corresponding goods or services.
In the aforementioned lotteries, for realization of the ability to accept from player, as payment for game bet the monetary prizes from his previous drafts, there must be created a database for all players with all winning tickets. Next, (FIG. 5) having a means of communication 51 RSU with these databases 52 (or at least with one of them), the lottery player can transfer from his TU information necessary for the realization of game bet, using requests made to these databases.
The information can be numbers (registration codes) of: winning tickets, winning coupons, goods or services of previous draws. A simple phone can be used as a TU. In this case, the information of his choice the player transfers using his voice.
For paying the game bets using cash or cashless monetary means (FIG. 6) one can use payment terminals 61 (for accepting cash) or individual payment means 64 (cashless payment, for example PC etc.). The RSU receives via communication connection 65 from these means (61 and 64) the information about the completion of payment by the player. Then it forms the ELB and sends it to the TU of the player.
For participation in public actions (lotteries, totalizators, game shows etc.) there can be used mixed schemes, in which the payment is received from previous wins or monetary means. FIG. 7 depicts block 71, comprising of draw-type ticket of lottery 72 and instant-type lottery tickets 74 and 75.
The cost of ticket 72 is $50, costs of tickets 74 and 75 is $25 each. The player buys the block 71, paying the cost of ticket 73 ($50). The order of drafts is as following:
1. on the day of draft of draw-type lottery, ticket 72 is drawn,
2. if the prize of ticket 72 is not less than $25 and not greater than $50, ticket 74 is drawn, if the prize of ticket 74 is not less than $25, ticket 75 is drawn, stop.
3. if the prize of ticket 72 is not less than $50, ticket 74 or 75 is drawn (the draft of ticket
74 or 75 is the removal of scratch-off material from it).
The rules of the instant-type lottery are as following: player can uncover one field in each row, starting from the bottom-most row. If the most recent uncovered field contains a monetary prize, the prize can be accepted by the player (if he discontinues uncovering fields), if the field is empty - player loses. FIG. 8 depicts, that ticket 74 of the player has lost, since he has uncovered one empty field, and ticket 75 has won $ 150.
All three tickets are printed on one sheet, and tickets 74 and 75 are covered by paper cover 76, which prevents uncovering their field. The conditions for validation of the block to be eligible for the prize are as following:
1. all three tickets are located on the same sheet (tearing off is prohibited),
2. to receive prize on ticket 72, paper cover 76 should be intact (removal of paper cover
76 implies that tickets 74 or 75 have been touched),
3. receiving of prizes on tickets 74 or 75 are according to rules described previously.
For example, if the prize of ticket 72 is $25, then the total prize of the player is 0, since he should have played ticket 74 first (he did not receive prize on that ticket, and therefore cannot continue playing). If the prize of ticket 72 is $50, then the total prize of the player is $150, and the order of playing tickets 74 and 75 is arbitrary. If the order of drafts is inverse (ticket 75 before ticket 74), the total prize of the player (considering prize of $25 on ticket 72) would have been $125.
To transfer rights of receiving the prize on the ticket (or part of one), the may be required a registration of the ticket or its hidden identifier 73. The registration of the ticket might be necessary when using hints during drafts or for informing about participation in additional drafts.
