Detailed Description
Example 1: a two-dimensional code label comprises a two-dimensional code image, wherein the two-dimensional code image is printed by at least two printing modes, each printing mode prints part of the two-dimensional code image, two-dimensional code image areas printed by each printing mode are formed by distributing two-dimensional code image information to different printer control modules through distribution information and printing, and all parts of image information distributed by the distribution information are transmitted and printed to form the two-dimensional code image corresponding to the complete two-dimensional code image information.
In the scheme, two-dimensional code image information is distributed to control modules of printers of different types, the contents printed by different printing modes are arranged in one image, the distinguishability is higher, the difficulty of imitation is increased, the consistent two-dimensional code image is difficult to imitate, if the imitation image of the two-dimensional code image is different from the imitation two-dimensional code image, the images printed by different types have information expression on the image, relevant expression information (such as the distribution information) can be analyzed and obtained by image acquisition, so that whether the distribution information exists on a platform or not can be judged, whether the two-dimensional code is printed by the distribution information issued by the platform or not can be confirmed, the authenticity can be easily judged, the distribution information reflected by different printing areas can be analyzed only by a corresponding method of the information distribution modes stored by the platform, and the distribution information cannot be mastered except the real platform, and thus the counterfeit two-dimensional code image cannot be printed according to the distribution information.
For the imitation two-dimensional code, the difficulty of printing the imitation is the lowest, the imitation cost is increased by printing in a printing mode, however, if the relation between the encryption and the corresponding image template can be cracked (because the image template needs to be stored in the printer), the imitation is possible, and the analysis of the two-dimensional code image formed by distributing different printing information to different types of printers is more unpredictable compared with a fixed encryption algorithm, and the distribution information cannot be obtained by decrypting the content of the printer.
As an embodiment, the distribution information and the two-dimensional code image information are generated by a platform, the platform stores the two-dimensional code image information corresponding to the two-dimensional code image and the distribution information corresponding to the two-dimensional code image information, the two-dimensional code image information is divided into a plurality of partial image information in a random number manner, and the two-dimensional code image corresponding to the complete two-dimensional code image information is obtained by printing paper fed by different types of print heads in a continuous printing process. In this further scheme, an allocation mode is given, namely a random number mode, and of course, in addition to the random number, a mode such as the allocation of custom points, position points and image points can be adopted. The specific scheme is as follows: generating two-dimensional code image information by a two-dimensional code generating library of the platform, wherein the two-dimensional code image information is stored in a two-dimensional array code [ N ] [ N ], and the size of the two-dimensional array information is N x N; generating two random numbers in multiple rounds, obtaining a batch of random two-dimensional array code [ N ] [ N ] partial arrays and non-random arrays from the random numbers, continuously generating the two random numbers in multiple rounds for the non-random arrays, obtaining a batch of random two-dimensional arrays and non-random arrays from the random numbers, stopping or circulating the method, randomly distributing the two-dimensional array code [ N ] [ N ] into a plurality of partial two-dimensional arrays by the random numbers, distributing the partial two-dimensional arrays to different printing control modules directly or in a combined mode, receiving the partial two-dimensional arrays by the printing modules, and printing the same paper feed by the printing heads according to the received partial two-dimensional numbers to form a complete two-dimensional code image.
In the present embodiment, two examples of random number acquisition allocation information will be described in detail:
the step of dividing the two-dimensional code image information into a plurality of partial image information in a random number mode specifically comprises the following steps:
generating two-dimensional code image information by a two-dimensional code generation library of the platform, wherein the two-dimensional code image information is stored in a two-dimensional array code [ N ] [ N ], and the size of the two-dimensional array information is N x N, N: according to a two-dimensional code generation rule, aiming at different information lengths and different two-dimensional code versions, N is equal to 21+4 m, wherein the value of m is (0< ═ m < (7);
a) generating two random numbers i, j in multiple rounds by using a random number generation algorithm or other modes, wherein 0< i, j < N, randomly dereferencing and distributing the two-dimensional array by the random numbers (i, j), and dividing the two-dimensional array into two parts, namely a two-dimensional array code [ i ] [ j ] and a two-dimensional array code [ N- ] [ N- ], wherein the two-dimensional array code [ N- ] [ N- ] is the rest two-dimensional array in the two-dimensional array code [ N ] [ N ] except the two-dimensional array code [ i ] [ j ];
the steps of printing the paper feed by different types of printing heads in the continuous printing process to obtain the two-dimensional code image corresponding to the complete two-dimensional code image information are as follows:
b) one of two-dimensional arrays code [ i ] [ j ] and code [ N- ] [ N- ] is sent to a printing control module for first-type printing to print a partial image of the two-dimensional code, and the other two-dimensional array is sent to a printing control module for second-type printing to print partial image information of the two-dimensional code;
c) two-dimensional arrays of codes [ i ] [ j ] and codes [ N- ] [ N- ] as partial image information, which are received by two different print control modules, and are printed by different print heads on the same paper feed according to the received partial image information to form a complete two-dimensional code image.
In this example, the image information to be printed is divided into two parts, one is a random part and the other is an un-random part, and the image information of the other part is sent to the corresponding type of printing, however, the method of random distribution is simpler, and in order to obtain more possible combinations, the invention further improves the algorithm and proposes the following scheme: the random and non-random parts are divided into a plurality of rounds to obtain a plurality of image information, and the image information is arranged or combined to be distributed to different types of printers, so that the possible combinations of the printing are obviously increased and are more difficult to decipher. Specifically, the step of dividing the two-dimensional code image information into a plurality of partial image information in a random number manner specifically includes:
generating two-dimensional code image information by a two-dimensional code generating library of the platform, wherein the two-dimensional code image information is stored in a two-dimensional array code [ N ] [ N ], and the size of the two-dimensional array information is N x N;
a) using a random number generation algorithm or otherwise, generating two random numbers i, j in multiple rounds, where 0< i, j < N, the two-dimensional array is randomly valued and distributed by the random number (i, j), dividing it into two parts, two-dimensional array code [ i ] [ j ] and two-dimensional array code [ N- ], respectively, where two-dimensional array code [ N- ] is the remaining two-dimensional array of two-dimensional array code [ N ] excluding two-dimensional array code [ i ] [ j ].
b) Generating two random numbers x, y in multiple rounds, wherein 0< x < N, j < y < N, randomly valuing and distributing the two-dimensional array code [ N- ], randomly valuing and distributing the random number (x, y), into two parts, namely a two-dimensional array code [ x ] [ y ] and a two-dimensional array code [ N- - ], wherein the two-dimensional array code [ N- - ] is the remaining two-dimensional array excluding the two-dimensional array code [ x ] [ y ] in the two-dimensional array code [ N- ];
taking two-dimensional arrays of code [ i ] [ j ] (M1), code [ x ] [ y ] (M2) and code [ N- - ] [ N- - ] (M3) as three-part two-dimensional code image information randomly generated by random numbers;
c) sending the image information of M1 and M3 to a thermal printing control module, and printing partial image information of the two-dimensional code by a thermal printing head;
d) sending the image information of the M2 to a needle printing control module, and printing partial image information of the two-dimensional code by a needle printing head;
e) partial image information of two-dimensional codes is printed as printing information by two different printing heads in combination, and a complete two-dimensional code image is printed.
The two-dimensional code label also comprises an RFID chip, distribution information of two-dimensional code image information or corresponding information thereof is recorded in the RFID chip, or a random number is recorded in the RFID chip, the random number divides the two-dimensional code image information into a plurality of random numbers in partial image information in a random number mode, the random number is a lower concept of the distribution information, by the above, two-dimensional codes printed by different printing modes are difficult to master the distribution information, so the same two-dimensional code image is difficult to obtain in imitation, different images can be judged to be fake images by a platform because the corresponding distribution information does not exist, however, in order to avoid the condition that the imitated two-dimensional code image is consistent with the imitated images, the label loses anti-counterfeiting effect, the RFID chip is further added in the scheme, and the printed two-dimensional code image and the RFID chip are combined to be used as the two-dimensional code label, scanning a two-dimensional code image in a two-dimensional code label by scanning equipment and uploading the two-dimensional code image to a platform, reading information stored in an RFID chip by a radio frequency system and uploading the information to the platform, matching the distribution information of the two-dimensional code image information corresponding to the two-dimensional code image by the platform according to the two-dimensional code image, judging whether the distribution information is consistent with the distribution information stored in the RFID chip, if so, verifying the identity uniqueness and the matching of the RFID chip and the two-dimensional code image mutually by the platform to be a true two-dimensional code issued by the platform, otherwise, the distribution information is false, in the method, the distribution information in the RFID chip is only required to be correspondingly consistent with the matching information corresponding to the information stored in the two-dimensional code scanning and obtained by scanning feedback, namely, the two-dimensional code label is considered to be a true two-dimensional code label, however, the distribution information in the RFID chip is possibly leaked, certainly, the expression of the distribution information can not directly know the printing mode because of the distribution information, and thus the effect is not great. In order to avoid the situation, an encryption algorithm is added in the RFID chip or information which is not direct distribution information and is stored in the RFID chip but corresponds to the distribution information is stored in the RFID chip, a printed two-dimensional code image and the RFID chip are combined to be a two-dimensional code label, a scanning device scans and uploads the two-dimensional code image in the two-dimensional code label to a platform, a radio frequency system reads the information stored in the RFID chip and uploads the information to the platform, the platform matches the distribution information of the two-dimensional code image information corresponding to the two-dimensional code image and the corresponding information of the distribution information corresponding to the two-dimensional code image according to the two-dimensional code image, whether the corresponding information of the distribution information is consistent with the corresponding information of the distribution information stored in the RFID chip or not is judged, if the two-dimensional code image is consistent with the two-dimensional code image information, a unique identity is verified, the verification of the RFID chip is combined with the, the anti-counterfeiting effect is strong. The stored information in the RFID chip is that the platform sends the distribution information of the two-dimensional code image information or the corresponding information thereof to the printer, and the printer stores the two-dimensional code image information in the RFID chip in a wireless transmission mode when the two-dimensional code image is printed. The RFID chip always has the mutually printable unique identity with the two-dimensional code image. The corresponding information of the corresponding distribution information can be a random number, for example, one piece of distribution information of the two-dimensional code image information corresponds to only one corresponding random number of the distribution information, the RFID chip stores the random number, the two-dimensional code storage information matches the distribution information, and the random number of the distribution information is found, so that the consistency of the two random numbers is judged, and whether the two-dimensional code label is true or not can be known. Of course, in addition to the random number, an image symbol such as a character may be used as the correspondence information.
In another scheme, a printed two-dimensional code image and an RFID chip are combined to be used as a two-dimensional code label, a scanning device scans and uploads the two-dimensional code image in the two-dimensional code label to a platform, a radio frequency system reads information stored in the RFID chip and uploads the information to the platform, and the platform retrieves distribution information of two-dimensional code image information corresponding to the two-dimensional code image according to the two-dimensional code image scanning information; the platform identifies the two-dimensional code image uploaded by scanning, reversely analyzes the two-dimensional code image into distribution information of the two-dimensional code image information according to printing areas (image identification) of different printing types in the two-dimensional code image, judges whether the distribution information of the two-dimensional code image, which is matched with the two-dimensional code image scanning information and stored in the platform, is consistent with the distribution information of the two-dimensional code image information obtained by reverse analysis, and judges whether the distribution information or the corresponding information of the two-dimensional code image, which is matched with the two-dimensional code image scanning information and stored in the platform, is consistent with the distribution information or the corresponding information stored in the RFID chip. And if the two-dimension code labels are consistent, judging the two-dimension code labels to be true, in the scheme, analyzing the image to obtain distribution information, judging the true or false, and further verifying the two-dimension code labels by using the identity information stored in the RFID chip so as to obtain the true or false. The method does not use the information expressed by the two-dimensional code to match the distribution information, but has the feedback information reflected by the two-dimensional code image (printing areas with different printing modes) to match the distribution information, of course, the two schemes are combined, the two-dimensional code storage information and the matching information corresponding to the two-dimensional code image information are matched with the information stored in the RFID chip, and if the matching is true, the anti-counterfeiting mode is more powerful.
In this embodiment, a printer for printing a two-dimensional code image is described, which includes a thermal position detection sensor, a thermal print head, a paper feeding assembly, a needle print position detection sensor, a needle print head, and a control system, where the control system is connected to the thermal position detection sensor, the thermal print head, the paper feeding assembly, the needle print position detection sensor, and the needle print head, and the control system includes a thermal print control module and a needle print control module, and when the paper is fed to the thermal print head, the thermal position detection sensor detects the paper feeding and feeds back a signal to the control system, and the thermal print control module of the control system outputs image information to be thermally printed to the thermal print head according to an instruction to thermally print a corresponding portion of the two-dimensional code image, and the paper feeding assembly rubs the paper to advance the paper to reach the needle print position detection sensor in response to the, the stitch position detection sensor detects paper feeding and feeds back signals to the control system, and a stitch printing control module of the control system outputs image information needing stitch printing to a stitch printing head according to instructions and performs stitch printing on a corresponding part of the two-dimensional code image.
