Description

Stamp printing system of a digital postage machine

technical field

The invention relates to a printing system of a digital postage machine, in particular to a stamp printing system of a digital postage machine.

Background technique

With the development of high technology, the use of digital postage machines to print postage stamps has been greatly developed and applied in the postal departments of many countries in recent years. Compared with stamps that require high anti-counterfeiting technology and printing technology, digital postage machines use ordinary printing equipment, and the stamping patterns and colors printed out are much simpler, and anti-counterfeiting technology is easy to master. Therefore, counterfeit stamps on the market Digital postage stamps appear from time to time, causing great losses to postal operators and consumers.

At present, there are two-dimensional barcode postmarks used for anti-counterfeiting of postage stamps, but the verification of two-dimensional barcodes is more complicated, and special equipment must be used, and the imitation cannot be identified with the naked eye, which improves the front-line anti-counterfeiting inspection. cost.

Contents of the invention

In order to solve the problems of complicated verification procedures and high anti-counterfeiting costs in the prior art, a stamp printing system for digital postage machines is provided. This printing system is simple and reliable in verification, does not require special equipment, and effectively reduces anti-counterfeiting costs.

In order to solve the above problems, the technical scheme adopted in the present invention includes

A stamp printing system for a digital postage machine, including a data acquisition module, a data processing module, and a printing module. The data acquisition module acquires the machine code, cumulative printing quantity, and batch data of the postage machine; the data processing module includes a data grouping module and a data processing module. Encryption module, wherein the data grouping module divides the obtained data into two arrays and a batch identifier, the machine code is the first array, the accumulated printing quantity is the second array, the batch printing data is the batch identifier, and the data encryption module according to the first array The first array, the second array and the batch identification are encrypted and calculated to generate a verification array; the printing module is used to output and print the data acquired by the data module and the array obtained after processing by the data processing module.

The machine code is six digits, the first three digits are English letters, and the last three digits are numbers.

The cumulative print quantity is 8 digits.

The check array is four characters.

Described encryption calculation module is processed according to the following steps:

Step 1: According to the batch identification, divide the accumulative printing quantity of the first postage machine when printing the stamp of the batch by a constant 62 to obtain the first remainder, and the first remainder corresponds to the character of the first coding table as the first bit check code;

The second step: the sum of the first four digits of the accumulated print quantity and the last three digits of the machine code, the sum value corresponds to the character of the first code list as the second check code;

The third step: the sum of the last four digits of the accumulated print quantity and the last three digits of the machine code, the sum value corresponds to the character of the first code list as the third check code;

Step 4: When printing the batch of stamps, divide the cumulative print quantity by a constant 62 to obtain a remainder, subtract the remainder from the cumulative print quantity to obtain the second remainder, divide the second remainder by the constant 62 to obtain the third Remainder, the third remainder corresponds to the second coding table to obtain a distinguishing character, the product of the second remainder and the sum of the last three digits of the machine code is used as a step value, and the second coding table is carried out with the distinguishing character as the starting point Loop, the character obtained by advancing the step value backwards from the distinguishing character is the fourth check code.

The coding table used in the first step to the third step is

The coding table used in the fourth step is

The printing module outputs and prints the machine code of the postage machine acquired by the data acquisition module, the accumulated printing quantity, and the check code calculated by the data processing module.

Use numbers and English characters to display the anti-counterfeiting code, combine the code table, combine the machine code of each postage machine, record the batch information printed in each batch, and the accumulated data of printing, so that each group of anti-counterfeiting codes is unique and can be checked , and can be distinguished by naked eyes, reducing the cost of authenticity verification. In actual use, no special equipment is even required. The front-line anti-counterfeiting inspectors can install the software that can enter the verification calculation on the mobile phone they carry every day, and can verify the authenticity of the stamp on the mobile phone. Using the method of installing software on the mobile phone, no additional investment is required for the verification equipment, which greatly reduces the cost of anti-counterfeiting, and the mobile phone has very good portability.

detailed description

Embodiment one

When the current batch is printed, the total cumulative number of pieces when the first letter is printed is eight digits 96506506, the machine code is CPU123, and the four-digit check code is generated according to the following steps:

The remainder obtained by dividing the total accumulated pieces of the machine by 62 is r: r=MOD(96506506, 62)=34.

The parameter w is obtained by adding the last three digits of the machine code: w = (1+2+3) = 6.

Add up the first four digits of the total accumulated pieces of the machine to get the parameter u: u=20=(9+6+5+0).

The parameter x is obtained by adding w and u: x=u+w=20+6=26.

Add up the last four digits of the total accumulated pieces of the machine to get the parameter v: v =17=(6+5+0+6).

Add v and u to get the parameter y: y=v+w=17+6=23.

Corresponding r, x, y with the numerical values in the first encoding table respectively, can obtain three check characters, r value 34 corresponds to I, x value 26 corresponds to A, y value 23 corresponds to x. The first coding table is as follows:

The 4th digit of the check code:

The total cumulative number of machines is 96506506 minus the r value to get a difference 96506472, the remainder i obtained by dividing the difference 96506472 by the constant 62 is 0, and then dividing the remainder 0 by the constant 26 to obtain the remainder 0, the remainder 0 and the second Correspond with the data in the coding table, find the corresponding character is A, start from A as 0, loop the second coding table from head to tail, step forward the product of i and w to 0, and finally get the fourth check character for A.

The second coding table is as follows:

Finally, the four-digit check code is: I A x A.

When printing out, print out the machine code of the postage machine, the cumulative printing quantity of each envelope or label and the four-digit check code as the anti-counterfeiting code 1.

In this example, the anti-counterfeiting codes are arranged: the first column on the left is the machine code of the postage machine, the eight digits on the upper right are the cumulative number of printed pieces of the machine when printing the label, and the four digits on the lower right are the check code.

What is given in this embodiment is the anti-counterfeiting coding process of the first printed label of this batch. In the anti-counterfeiting coding of subsequent printouts in this batch, the machine code of the postage meter remains unchanged, and the cumulative printing times increase in turn. Change, the corresponding check code also changes accordingly.
