Referring to fig. 1 to fig. 2, a first embodiment of the present invention is:
a lottery anti-counterfeiting method, comprising the steps of:
s1, pre-printing a preset lottery pattern 103 in a preset graphic area 101 in a password area for printing a lottery password on the lottery ticket 100 to be printed;
the preset pattern area 101 is located in the middle of the password area, the preset pattern area 101 is an axisymmetric pattern, and the preset lottery pattern 103 is a lottery trademark pattern or a lottery category pattern corresponding to different lottery playing methods. In this embodiment, as shown in fig. 2, the preset graphic area 101 is a circle, and the preset lottery pattern 103 is a lottery trademark pattern, in other equivalent embodiments, the preset graphic area 101 may also be a square, and the preset lottery pattern 103 may be a pattern of a category to which the current lottery belongs.
S2, when a lottery password is printed on the lottery to be printed 100, taking all other point locations in the password area except the first pattern point location set occupied by the preset lottery pattern 103 as a second pattern point location set for printing the lottery password, and generating the lottery password formed by the point locations in the second pattern point location set, wherein the second pattern point location set comprises the point locations which are located in the preset pattern area 101 and do not belong to the first pattern point location set;
and S3, printing the lottery password on the area except the preset graphic area 101 in the password area by using colored ink, and printing the lottery password on the preset graphic area 101 by using near infrared absorption ink containing hydrogen group components to obtain the printed lottery password.
Therefore, after seeing the preset lottery pattern 103 in fig. 2, the lottery players and lawbreakers easily consider the preset lottery pattern to be a trademark pattern, so that the hidden password information is not easily perceived by the lottery players and the lawbreakers, and only the information in the other areas except the preset pattern area 101 is considered to be the lottery password information to confuse the lawbreakers, thereby reducing the risk of falsifying prize money by counterfeiting the lottery ticket and improving the security of the lottery ticket.
Referring to fig. 1 to fig. 2, a second embodiment of the present invention is:
on the basis of the first embodiment, the step S2 specifically includes the following steps:
s21, dividing the password area into a preset graphic area 101 and a printing display area 102 except the preset graphic area 101, wherein a first identification area is arranged in the preset graphic area 101, and a second identification area is arranged in the printing display area 102;
namely, the print hidden area except the preset lottery pattern 103 in the print display area 102 and the preset graphic area 101 is provided with an identification area to carry identification information.
In this embodiment, the point locations occupied by the first identification area and the second identification area respectively occupy less than 10% of the whole password area, and specific occupation ratios can be selected according to actual situations.
S22, setting point positions occupied by preset lottery patterns 103 as a first pattern point position set, setting point positions in a first identification area as a first identification point position set, setting point positions in a second identification area as a second identification point position set, and taking all other point positions except the first pattern point position set, the first identification point position set and the second identification point position set in a password area as a second pattern point position set for printing lottery passwords;
that is, all the point locations except the preset lottery pattern 103 and the two identification areas in the whole password area are used for generating lottery passwords, and the generation of the lottery passwords only needs to be corresponding to the point locations in the area according to the existing generation algorithm.
S23, when a lottery password is printed on the lottery to be printed 100, generating a lottery password formed by point positions in a second pattern point position set, first identification information formed by point positions in a first identification area and second identification information formed by point positions in a second identification area, wherein the first identification information and the second identification information pass the lottery verification when appearing or not appearing at the same time and fail in the verification when only one identification information appears and send alarm information to a background server;
as can be seen from the above, in the present embodiment, the authenticity of the lottery ticket is confirmed by counting the number of the identification information, and the generation of the specific identification information is not discussed in the present embodiment, and the existing information capable of performing identification may be adopted.
In a preferred embodiment, the first identification information and the second identification information form a pair of random key information, and public keys of the random key information are used for encrypting lottery uploading data and then uploading the encrypted lottery uploading data to the background server.
Therefore, during verification, the identification information of the two identification areas is uploaded to the background server side together with the encrypted lottery uploading data, the background server side decrypts the stored encrypted lottery uploading data by using the private keys in the two identification information, if decryption is successful, the identification information is legal, and if decryption is unsuccessful, the lottery uploading data needing comparison cannot be obtained, so that the security of the lottery uploading data in the transmission process is ensured, and the effects of improving the security of the lottery uploading data and verifying the validity of the identification information can be achieved at the same time.
Wherein, step S3 specifically includes the following steps:
printing the lottery password and the second identification information on the area except the preset graphic area 101 in the password area by using colored ink, and printing the lottery password and the first identification information on the preset graphic area 101 by using near infrared absorption ink containing hydrogen radical components to obtain the printed lottery password.
Therefore, when the lottery player purchases the conventional lottery ticket, the lottery ticket is verified to be free of any identification information by winning the lottery ticket, and the lottery ticket is verified according to the conventional verification method. When the lottery buyer purchases the printed lottery in this embodiment, the two pieces of identification information are obtained by the lottery winning verification, the preset lottery pattern 103 and the identification information of the two identification areas are removed first, and the password formed by the remaining point locations and the password of the data of the background server are verified. When the lottery ticket is forged by lawbreakers, the hidden printing information in the preset graphic area 101 is not displayed by the picture shared by the lawbreakers, and the lottery ticket forged by the lawbreakers can only recognize one piece of identification information, so that the recognized lottery ticket is suspected to be forged. In addition, the damage of the lottery ticket on the password area due to improper storage is generally water stain, abrasion and the like, and the condition that the identification information with two small occupied area proportion is complete and one is damaged can be almost ignored, so that the damage of the lottery ticket on the password area due to improper storage is basically not the identification information or has two identification information, thereby leading the prior conventional lottery ticket and the lottery ticket of the invention to carry out winning verification on one verification device and automatically identifying the counterfeit suspicion.
Referring to fig. 1 to 2, a third embodiment of the present invention is:
a lottery anti-counterfeiting method, which is based on the second embodiment, in this embodiment, generation of identification information is further limited, that is, steps S21 to S23 are replaced with:
s21, dividing the password area into a preset graphic area 101 and a printing display area 102 except the preset graphic area 101, dividing the preset graphic area 101 and the printing display area 102 into a plurality of data sub-areas, randomly selecting one data sub-area from the plurality of data sub-areas including the lottery password of the preset graphic area 101 as a first identification area, randomly selecting one data sub-area from the plurality of data sub-areas of the printing display area 102 as a second identification area, merging the first identification area and the second identification area, and then performing hash calculation to obtain an anti-counterfeiting hash value.
Therefore, in the embodiment, the data in the original data subarea is used as the identification data, no new identification data is required to be generated, and no additional identification area is required, so that more point positions are reserved for encryption, namely, lottery printing steps are reduced, and the lottery security is improved.
S22, setting the point positions occupied by the preset lottery pattern 103 as a first pattern point position set, and taking all other point positions except the first pattern point position set in the password area as a second pattern point position set for printing the lottery password.
S23, when the lottery password is printed on the lottery to be printed 100, generating the lottery password formed by the point positions in the second pattern point position set, and marking the data sub-regions corresponding to the first identification region and the second identification region, wherein the first identification information and the second identification information pass the lottery verification when appearing or not appearing at the same time, and fail the verification when only one identification information appears, and sending alarm information to the background server.
And uploading the anti-counterfeiting hash value, the marks of the data subareas corresponding to the first identification area and the second identification area and the pre-uploaded lottery uploading data to a background server.
For example, the whole preset graphic area 101 and the printing display area 102 are divided into 4 × 4 data sub-areas, the areas are marked as the first rows 00, 01, 02, 03 according to the area correspondence, the second rows 10, 11, 12, 13 are analogized in sequence, the second row and the third column in the preset graphic area 101 are marked as 12, the fourth row and the first column in the printing display area 102 are marked as 31, and the marks of the data sub-areas corresponding to the anti-counterfeiting hash values, 12, and 31 and the pre-lottery uploading data are uploaded to the background server.
Therefore, when a certain lottery ticket is subsequently verified, the preset graphic area 101 and the printing display area 102 are divided into equal sub-areas, the data of the data sub-areas corresponding to the marks are combined and then hash calculation is calculated, the hash value calculated during verification is compared with the anti-counterfeiting hash value uploaded during lottery ticket purchase, and if the comparison is not consistent, the lottery ticket is considered to be suspected of counterfeiting.
As for the area compared with the conventional lottery ticket, it is sufficient to distinguish whether there is the preset lottery pattern 103, the preset graphic area 101, or the amount of data.
Step S3 is replaced by:
printing lottery passwords on the areas except the preset graphic area 101 in the password area by using colored ink, and printing the lottery passwords on the preset graphic area 101 by using near infrared absorption ink containing hydrogen radical components to obtain the printed lottery passwords.
Referring to fig. 1 to fig. 2, a fourth embodiment of the present invention is:
on the basis of the second embodiment, in this embodiment, a scheme corresponding to the "first identification information and the second identification information form a pair of random key information" in the embodiment is replaced with:
acquiring serial number information of a printed surface of the lottery ticket 100 to be printed, and respectively using the serial number information as first identification information and second identification information after the serial number information is processed in a preset mode.
The side for printing lottery ticket code is hot-printed with information during betting, so that the side is called hot-printed side, and the other side of the hot-printed side is the printed side.
The preset processing mode includes that the forward sequence and the reverse sequence of the serial number information are used as the first identification information and the second identification information, for example, the forward sequence 2058423159030 of the serial number information, the reverse sequence is 0309513248502, 2058423159030 or 0309513248502, and the other is used as the first identification information, and the other is used as the second identification information.
Or the serial number information is divided into two parts as the first identification information and the second identification information, for example, 2058423 and 159030, 2058423 or 159030 is used as the first identification information, and the other is used as the second identification information.
Or adding the current bit and the adjacent bit of the serial number information to obtain a mantissa, and subtracting the current bit and the adjacent bit of the serial number information to obtain a mantissa, wherein the adjacent bit may be a previous bit or a next bit, and the first bit and the last bit are adjacent bits connected end to end, for example, 253265464932 is obtained by adding the current bit and the next bit to obtain the mantissa by 2058423159030, 253421244933 is obtained by subtracting the current bit and the next bit to obtain the mantissa 253265464932 or 253421244933 as the first identification information, and the other one is used as the second identification information.
In other equivalent embodiments, other preset processing modes may be performed on the serial number information, so as to ensure that the preset processing modes for obtaining the first identification information and the second identification information are not completely the same.
Therefore, the serial number is adopted for identification generation, so that the identification information is convenient to generate, the serial number is positioned on the printing surface and generally cannot be leaked out along with photographing, and lawless persons can hardly crack the identification information through the serial number, so that the identification information is convenient to generate and the safety of the identification information is guaranteed.
