A high-concealment lottery anti-counterfeiting method and system

Abstract

This invention relates to the field of anti-counterfeiting technology for lottery tickets, and particularly to a highly concealed lottery anti-counterfeiting method and system. Building upon traditional QR code anti-counterfeiting, this method uses server-side calculations to associate serial number information and betting information with the often-overlooked design of the lottery ticket's back. For the user, the back information appears randomly generated, making the association difficult to detect. Furthermore, anti-counterfeiting coordinates are marked on the back information. Since these are dots, the printing cost is lower than that of QR codes, and they are difficult to detect. In cases where the back of a lottery ticket often contains a lot of information, this makes the anti-counterfeiting information more concealed and harder to copy.

Description

Technical Field

[0001] This invention relates to the field of anti-counterfeiting technology for lottery tickets, and in particular to a highly concealed anti-counterfeiting method and system for lottery tickets. Background Technology

[0002] As a form of public entertainment with a wide audience, lotteries attract the attention and participation of a large number of people. The audience is so broad that it includes people of different genders, ages, occupations, and educational backgrounds. Lottery holders can span various social classes and age groups; therefore, anti-counterfeiting measures are of paramount importance.

[0003] Existing anti-counterfeiting technologies include invisible QR code anti-counterfeiting technology. Invisible QR code anti-counterfeiting technology refers to outputting a two-dimensional barcode through printing or printing using colorless invisible consumables. The two-dimensional barcode is invisible to the naked eye under normal conditions, and only specialized reading devices can decipher the encrypted information within the QR code in this state. This is an automatic identification technology. Colorless invisible consumables include fluorescent ink, fluorescent toner, fluorescent ribbon, and infrared ink. Invisible QR code anti-counterfeiting technology hides the QR code, and in some applications, it can at least prevent users from directly scanning the QR code to obtain information and distinguish genuine from counterfeit products through the invisible QR code, thus serving an anti-counterfeiting function.

[0004] The reason why invisible QR codes are difficult to copy lies in their complex, time-consuming, and costly production process. However, lottery tickets, depending on the number of bets, typically cost only a few dollars or even a dozen dollars per ticket, and are printed in huge quantities, making the use of invisible QR code anti-counterfeiting technology on them impractical.

[0005] Therefore, how to achieve effective, covert, and low-cost lottery anti-counterfeiting is the technical problem that needs to be solved. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a highly concealed lottery anti-counterfeiting method and system, so as to achieve effective, covert and low-cost lottery anti-counterfeiting.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A highly concealed lottery anti-counterfeiting method includes the following steps:

[0009] S1. The lottery sales terminal obtains the serial number information printed on the pre-made lottery ticket and sends the ticket information, including the serial number information and the user's betting information to be printed, to the server.

[0010] S2. The server generates a QR code based on the ticket information and performs obfuscation and encryption calculations to generate a string of digital codes.

[0011] S3. The server calculates the back information number and several anti-counterfeiting coordinate points by using a preset algorithm, and saves the ticket information, the QR code, the unique code, the back information number and the anti-counterfeiting coordinate points together.

[0012] S4. The server returns the QR code, the back information number, and the anti-counterfeiting coordinate point information to the lottery sales terminal.

[0013] S5. The lottery sales terminal prints the betting information and the QR code on the front of the pre-made lottery ticket, and prints the back printing information corresponding to the unique back information number on the back of the pre-made lottery ticket.

[0014] S6. The lottery sales terminal uses near-infrared absorbing ink to mark anti-counterfeiting coordinate points on the back of the pre-made lottery ticket based on the anti-counterfeiting coordinate point information.

[0015] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows:

[0016] A highly concealed lottery anti-counterfeiting system includes a lottery sales terminal and a server terminal. The lottery sales terminal includes a first processor, a first memory, and a first computer program stored in the first memory and executable on the first processor. The server terminal includes a second processor, a second memory, and a second computer program stored in the second memory and executable on the second processor. When the first processor executes the first computer program, it performs the following steps:

[0017] S1. Obtain the serial number information printed on the pre-made lottery ticket, and send the ticket information including the serial number information and the user's betting information to be printed to the server.

[0018] S5. Print the betting information and QR code on the front of the pre-made lottery ticket, and print the back information information corresponding to the unique back information number on the back of the pre-made lottery ticket.

[0019] S6. On the back of the pre-made lottery ticket, anti-counterfeiting coordinate points are made using near-infrared absorbing ink based on the anti-counterfeiting coordinate point information.

[0020] When the second processor executes the second computer program, it performs the following steps:

[0021] S2. Generate a QR code based on the ticket information, and simultaneously perform obfuscation and encryption calculations to generate a string of digital codes;

[0022] S3. Calculate the back information number and several anti-counterfeiting coordinate point information by using the digital code through a preset algorithm, and save the ticket information, the QR code, the unique code, the back information number and the anti-counterfeiting coordinate point information together.

[0023] S4. Return the QR code, the back information number, and the anti-counterfeiting coordinate point information to the lottery sales terminal.

[0024] The beneficial effects of this invention are as follows: This invention provides a highly concealed lottery anti-counterfeiting method and system. Based on traditional QR code anti-counterfeiting, it uses server-side calculations to associate serial number information and betting information with the style of the lottery ticket back information, which is often overlooked. For users, the back information is essentially randomly generated, making it difficult to detect the association. At the same time, anti-counterfeiting coordinate points are marked on the back information. Since these are in the form of dots, the printing cost is lower than that of QR codes, and they are difficult to detect. Furthermore, given that the back of the lottery ticket often contains a lot of content, this makes the anti-counterfeiting information more concealed and difficult to copy.

[0029] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please refer to Figure 1 A highly concealed lottery anti-counterfeiting method includes the following steps:

[0031] S1. The lottery sales terminal obtains the serial number information printed on the pre-made lottery ticket and sends the ticket information, including the serial number information and the user's betting information to be printed, to the server.

[0032] S2. The server generates a QR code based on the ticket information and performs obfuscation and encryption calculations to generate a string of digital codes.

[0033] S3. The server calculates the back information number and several anti-counterfeiting coordinate points by using a preset algorithm, and saves the ticket information, the QR code, the unique code, the back information number and the anti-counterfeiting coordinate points together.

[0034] S4. The server returns the QR code, the back information number, and the anti-counterfeiting coordinate point information to the lottery sales terminal.

[0035] S5. The lottery sales terminal prints the betting information and the QR code on the front of the pre-made lottery ticket, and prints the back printing information corresponding to the unique back information number on the back of the pre-made lottery ticket.

[0036] S6. The lottery sales terminal uses near-infrared absorbing ink to mark anti-counterfeiting coordinate points on the back of the pre-made lottery ticket based on the anti-counterfeiting coordinate point information.

[0037] As can be seen from the above description, the beneficial effects of the present invention are as follows: The highly concealed lottery anti-counterfeiting method and system of the present invention, based on traditional QR code anti-counterfeiting, uses server-side calculation to associate serial number information and betting information with the style of information on the back of the lottery ticket, which is often overlooked by people. Moreover, for users, the information on the back of the lottery ticket is equivalent to being randomly generated, making it difficult to discover the correlation. At the same time, anti-counterfeiting coordinate points are marked in the information on the back of the lottery ticket. Since they are in the form of points, the printing cost is lower than that of QR codes, and they are difficult to detect. In addition, when there is a lot of content on the back of the lottery ticket, the anti-counterfeiting information is more concealed and difficult to copy.

[0038] Furthermore, the algorithm for calculating the reverse side information number based on the digital code is as follows:

[0039] The quantity of the pre-made back information is obtained, and the remainder of the digital code is calculated based on the quantity of the back information to obtain the back information number.

[0040] As described above, the back information number is calculated using the above method. The back information of the lottery ticket is then linked to the back information, digital code, and ticket information through the back information number, which is used to verify the authenticity of the lottery ticket.

[0041] Furthermore, the algorithm for calculating the anti-counterfeiting coordinate points based on the digital code is as follows:

[0042] Divide the pre-made lottery tickets into an N*N grid, where N is 10 to the power of n and n is a positive integer;

[0043] The digital encoding obtains a first number of bits of digital information from a preset direction;

[0044] The first quantity is the preset number of anti-counterfeiting coordinate points * 2 * n;

[0045] The digital information of the first number of digits is split to obtain the grid coordinates of the anti-counterfeiting coordinate points.

[0046] As described above, by dividing the pre-made lottery tickets into grids, a grid coordinate system is established. By splitting the digital information, the grid coordinates of the anti-counterfeiting coordinate points are obtained. At the same time, the above method can ensure that the horizontal and vertical coordinates do not exceed the grid area, thus ensuring the validity of the coordinates.

[0047] Furthermore, the near-infrared absorbing ink is a near-infrared absorbing ink containing hydrogen groups.

[0048] As described above, near-infrared absorbing inks containing hydrogen groups are used. These inks contain compounds with hydrogen groups, which can exhibit significant absorption peaks in the near-infrared spectral range for verification and identification. Conventional printing techniques cannot accurately reproduce near-infrared absorbing inks containing hydrogen groups.

[0049] Furthermore, the ticket information also includes the lottery sales terminal number;

[0050] The color of the near-infrared absorbing ink used in the lottery sales terminal is obtained by pre-assigning and associating it with the server, and the association relationship is saved on the server.

[0051] As described above, the ink color of the anti-counterfeiting coordinate points is associated with the lottery sales terminal to further ensure the accuracy of the verification.

[0052] Please refer to Figure 2 A highly concealed lottery anti-counterfeiting system includes a lottery sales terminal and a server terminal. The lottery sales terminal includes a first processor, a first memory, and a first computer program stored in the first memory and executable on the first processor. The server terminal includes a second processor, a second memory, and a second computer program stored in the second memory and executable on the second processor. When the first processor executes the first computer program, it performs the following steps:

[0053] S1. Obtain the serial number information printed on the pre-made lottery ticket, and send the ticket information including the serial number information and the user's betting information to be printed to the server.

[0054] S5. Print the betting information and QR code on the front of the pre-made lottery ticket, and print the back information information corresponding to the unique back information number on the back of the pre-made lottery ticket.

[0055] S6. On the back of the pre-made lottery ticket, anti-counterfeiting coordinate points are made using near-infrared absorbing ink based on the anti-counterfeiting coordinate point information.

[0056] When the second processor executes the second computer program, it performs the following steps:

[0057] S2. Generate a QR code based on the ticket information, and simultaneously perform obfuscation and encryption calculations to generate a string of digital codes;

[0058] S3. Calculate the back information number and several anti-counterfeiting coordinate point information by using the digital code through a preset algorithm, and save the ticket information, the QR code, the unique code, the back information number and the anti-counterfeiting coordinate point information together.

[0059] S4. Return the QR code, the back information number, and the anti-counterfeiting coordinate point information to the lottery sales terminal.

[0060] As can be seen from the above description, the beneficial effects of the present invention are as follows: The highly concealed lottery anti-counterfeiting method and system of the present invention, based on traditional QR code anti-counterfeiting, uses server-side calculation to associate serial number information and betting information with the style of information on the back of the lottery ticket, which is often overlooked by people. Moreover, for users, the information on the back of the lottery ticket is equivalent to being randomly generated, making it difficult to discover the correlation. At the same time, anti-counterfeiting coordinate points are marked in the information on the back of the lottery ticket. Since they are in the form of points, the printing cost is lower than that of QR codes, and they are difficult to detect. In addition, when there is a lot of content on the back of the lottery ticket, the anti-counterfeiting information is more concealed and difficult to copy.

[0061] Furthermore, when the second processor executes the second computer program, the algorithm for calculating the back information number based on the digital code is as follows:

[0062] The quantity of the pre-made back information is obtained, and the remainder of the digital code is calculated based on the quantity of the back information to obtain the back information number.

[0063] As described above, the back information number is calculated using the above method. The back information of the lottery ticket is then linked to the back information, digital code, and ticket information through the back information number, which is used to verify the authenticity of the lottery ticket.

[0064] Furthermore, when the second processor executes the second computer program, the algorithm for calculating the anti-counterfeiting coordinate points based on the digital code is as follows:

[0065] Divide the pre-made lottery tickets into an N*N grid, where N is 10 to the power of n and n is a positive integer;

[0066] The digital encoding obtains a first number of bits of digital information from a preset direction;

[0067] The first quantity is the preset number of anti-counterfeiting coordinate points * 2 * n;

[0068] The digital information of the first number of digits is split to obtain the grid coordinates of the anti-counterfeiting coordinate points.

[0069] Furthermore, as described above, by dividing the pre-made lottery tickets into grids, a grid coordinate system is established. By splitting the digital information, the grid coordinates of the anti-counterfeiting coordinate points are obtained. At the same time, the above method can ensure that the horizontal and vertical coordinates do not exceed the grid area, thus ensuring the validity of the coordinates.

[0070] Furthermore, the near-infrared absorbing ink is a near-infrared absorbing ink containing hydrogen groups.

[0071] As described above, near-infrared absorbing inks containing hydrogen groups are used. These inks contain compounds with hydrogen groups, which can exhibit significant absorption peaks in the near-infrared spectral range for verification and identification. Conventional printing techniques cannot accurately reproduce near-infrared absorbing inks containing hydrogen groups.

[0072] Furthermore, the ticket information also includes the lottery sales terminal number;

[0073] The color of the near-infrared absorbing ink used in the lottery sales terminal is obtained by pre-assigning and associating it with the server, and the association relationship is saved on the server.

[0074] As described above, the ink color of the anti-counterfeiting coordinate points is associated with the lottery sales terminal to further ensure the accuracy of the verification.

[0075] The present invention provides a highly concealed lottery anti-counterfeiting method and system, applicable to anti-counterfeiting protection in lottery sales.

[0076] Please refer to Figure 1 Embodiment 1 of the present invention is as follows:

[0077] A highly concealed lottery anti-counterfeiting method includes the following steps:

[0078] S1. The lottery sales terminal obtains the serial number information printed on the pre-made lottery ticket and sends the ticket information, including the serial number information and the user's betting information to be printed, to the server.

[0079] S2. The server generates a QR code based on the ticket information and performs obfuscation and encryption calculations to generate a string of digital codes.

[0080] S3. The server calculates the back information number and several anti-counterfeiting coordinate points by using a preset algorithm, and saves the ticket information, the QR code, the unique code, the back information number and the anti-counterfeiting coordinate points together.

[0081] S4. The server returns the QR code, the back information number, and the anti-counterfeiting coordinate point information to the lottery sales terminal.

[0082] S5. The lottery sales terminal prints the betting information and the QR code on the front of the pre-made lottery ticket, and prints the back printing information corresponding to the unique back information number on the back of the pre-made lottery ticket.

[0083] S6. The lottery sales terminal uses near-infrared absorbing ink to mark anti-counterfeiting coordinate points on the back of the pre-made lottery ticket according to the anti-counterfeiting coordinate point information.

[0084] The near-infrared absorbing ink is a near-infrared absorbing ink containing hydrogen groups.

[0085] In this embodiment, the anti-counterfeiting coordinate point is a dot with a diameter of 1mm.

[0086] Based on the above steps, in this embodiment there are three markings: a QR code, information on the back, and anti-counterfeiting coordinate points.

[0087] QR codes provide users with initial anti-counterfeiting verification; users can scan the QR code to access lottery betting information through a specific app. However, some criminals may use photocopying or other image duplication methods to copy existing lottery tickets for illegal sales. The information on the back of the lottery ticket often includes promotional slogans, images, and instructions, which are easily overlooked, especially due to the randomness of its generation. Therefore, when criminals retain information from the front of the ticket, they may neglect the back information, for example, copying one or two pieces of information before using it randomly. In such cases, matching the back information can often more directly determine the authenticity of the lottery ticket.

[0088] Meanwhile, since the content and colors of the information on the back are often quite complex, the anti-counterfeiting coordinate points embedded within them play an even more significant role. Due to the inherent transparency of the colors, they are difficult to detect, and even more so on the complex background. Furthermore, it is difficult for criminals to preserve these coordinate points through image storage. Even if criminals accidentally discover color anomalies under specific circumstances, the anti-counterfeiting points are very small, and their positions often differ between different lottery tickets. Therefore, they are likely to mistakenly attribute these anomalies to printing errors and ignore them. This plays a crucial role in anti-counterfeiting identification when criminals copy the entire lottery ticket image.

[0089] Embodiment 2 of the present invention is as follows:

[0090] A highly concealed lottery anti-counterfeiting method differs from Embodiment 1 in that, in this embodiment, the algorithm for calculating the back information number based on the digital code is as follows:

[0091] The quantity of the pre-made back information is obtained, and the remainder of the digital code is calculated based on the quantity of the back information to obtain the back information number.

[0092] In other equivalent embodiments, the algorithm can be modified, for example, by taking the data of a preset number of digits before or after the digital encoding, performing a remainder based on the number of back information, or by adding / subtracting / multiplying / dividing a certain value before performing a remainder, that is, performing a fixed operation first and then performing a remainder operation.

[0093] Embodiment 3 of the present invention is as follows:

[0094] A highly concealed lottery anti-counterfeiting method differs from implementations one or two in that, in this embodiment, the algorithm for calculating the anti-counterfeiting coordinate points based on the digital code is as follows:

[0095] Divide the pre-made lottery tickets into an N*N grid, where N is 10 to the power of n and n is a positive integer;

[0096] The digital encoding obtains a first number of bits of digital information from a preset direction;

[0097] The first quantity is the preset number of anti-counterfeiting coordinate points * 2 * n;

[0098] The digital information of the first number of digits is split to obtain the grid coordinates of the anti-counterfeiting coordinate points.

[0099] In this embodiment, N is 100 as an example.

[0100] Assuming the obtained digital code is 98456321789563214789, the number of anti-counterfeiting coordinate points is 3.

[0101] In this embodiment, 12-bit digital information (3*2*2) is obtained from the tail direction: 789563214789.

[0102] The 12-digit code is split to obtain the grid coordinates of three anti-counterfeiting coordinate points: (78, 95), (63, 21) and (47, 89).

[0103] In addition, generally speaking, due to the randomness of digital encoding, grid coordinates are unlikely to repeat, but it is still possible for coordinates to repeat.

[0104] At this point, the number of anti-counterfeiting coordinate points is only 2.

[0105] That is, the number of anti-counterfeiting coordinate points also has a certain degree of randomness.

[0106] In other equivalent embodiments, in order to ensure that the number of anti-counterfeiting coordinates is uniform, when coordinates are repeated, 2n bits of digital information are taken sequentially along a preset direction (the tail direction in this embodiment) and split into new grid coordinates. If the coordinates are still repeated, the value splitting continues.

[0107] Embodiment four of the present invention is as follows:

[0108] A highly concealed lottery anti-counterfeiting method, which differs from implementations one to three in that the ticket information also includes the lottery sales terminal number;

[0109] The color of the near-infrared absorbing ink used in the lottery sales terminal is obtained by pre-assigning and associating it with the server, and the association relationship is saved on the server.

[0110] In this embodiment, infrared absorbing inks of four display colors—red, yellow, blue, and white—are used. When the ink is put into use at the lottery sales terminal, the server randomly assigns the display color of the ink to it. Subsequently, it only uses the infrared absorbing ink of that display color to make anti-counterfeiting coordinate points.

[0111] The MAC address is used as the unique identifier for each lottery sales terminal.

[0112] At this point, the server stores the MAC address of the lottery sales terminal and the corresponding ink color used for display, thereby verifying the validity of the anti-counterfeiting coordinate points.

[0113] Embodiment five of the present invention is as follows:

[0114] A highly concealed lottery anti-counterfeiting method differs from embodiments one to four in that, in this embodiment, the user also needs to present their ID card or manually enter their ID card information when purchasing tickets, thereby enabling the lottery sales terminal to obtain the identity information of the ticket purchaser.

[0115] The lottery sales platform will also include the user's identity information in the ticket information and send it to the server for storage.

[0116] When a lottery ticket is being redeemed, if the anti-counterfeiting measures detect that the ticket is counterfeit, the lottery sales terminal assumes that the ticket may be lost or otherwise abnormal. In this case, the sales terminal initiates a prize redemption lock request to the server based on either the ticket's serial number or QR code. At this point, the user must present identification to redeem a legitimate ticket. The lottery sales terminal reads the identification information and compares it with the server's verification before the prize can be redeemed.

[0117] Please refer to Figure 2 Embodiment six of the present invention is as follows:

[0118] A highly concealed lottery anti-counterfeiting system 1 includes a lottery sales terminal 2 and a server terminal 5. The lottery sales terminal 2 includes a first processor 3, a first memory 4, and a first computer program stored in the first memory 4 and executable on the first processor 3. The server terminal 5 includes a second processor 6, a second memory 7, and a second computer program stored in the second memory 7 and executable on the second processor 6. When the first processor 3 executes the first computer program and when the second processor 6 executes the second computer program, they jointly implement the steps of any of the highly concealed lottery anti-counterfeiting methods described in embodiments one to six above.

[0119] In summary, the present invention provides a highly concealed lottery anti-counterfeiting method and system. Building upon traditional QR code anti-counterfeiting, it uses server-side calculations to associate serial number information and betting information with the often-overlooked design of the lottery ticket's back. For the user, the back information appears randomly generated, making the association difficult to detect. Furthermore, anti-counterfeiting coordinates are marked on the back information; since these are dots, the printing cost is lower than that of QR codes, and they are harder to detect. This also makes the anti-counterfeiting information more concealed and difficult to copy, especially when the back of the lottery ticket contains a lot of content.

[0120] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
