Problems solved by technology

[0002] In recent years, with the rapid development of the bill business, some lawbreakers have created counterfeit bills by cloning and altering bills, which not only caused heavy economic losses to the country, but also affected the stability of the financial order.
Among the counterfeit bills, ordinary bills (such as tax bills) have become the main forgery objects, but since the anti-counterfeiting digital is only printed on the surface of the paper, it is easy to be forged, so the original inquiry digital anti-counterfeiting label can no longer adapt Management Identification Requirements for Current Bills

Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0022] The present invention will be further described by taking the coding "Shaanxi University" as an example.

[0023] see figure 1 , the modern papermaking process includes making pulp in the pulp tank, then forming a line on the wire part 4, and sending it to the winder after being squeezed and dried. The digital encryption method of the fiber paper forming process based on the dot matrix pattern of the present invention is On the basis of the modern papermaking process, the following processes are added:

[0024] First, in the process of pulping, add about 30±5% magnetic fibers and mix them evenly;

[0025] Magnetic fibers can be Fe 3 O4, Fe 2 o 3 , CrO 2 Or trivalent iron oxide with cobalt added to iron oxide.

[0026] Second, a layer of partition board 2 is covered on the net part 4, and guide rails 3 are arranged above the partiti...

Abstract

A digitized encryption method for a fiber paper making process based on dot patterns comprises the following steps: adding magnetic fiber during a pulping process, and utilizing a magnetic dot code controller to control dot codes to act on the magnetic fiber in pulp during a pulp flowing process, so as to form magnetic dot patterns in paper, wherein the magnetic dot code controller is arranged above a mesh part, and comprises an input module, a conversion module, a storage module and a processing module; the input module and the conversion module are connected with each other, so as to input the dot patterns; the conversion module and the storage module are connected with each other to convert the input dot patterns into 16 * 16 dot data; and the processing module and the storage module are connected with each other to control the magnetic property of corresponding dots on the magnetic dot code controller. According to the invention, the interior of the paper is encrypted magnetically during a paper making process, so that people cannot see the interior of the paper visually, and scanning and duplication are avoided; and stored information is converted into dot codes during the encryption process, so that the data can be stored in the paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a digital encryption method of fiber paper-forming process based on dot matrix graphics. Background technique [0002] In recent years, with the rapid development of the bill business, some lawbreakers have created counterfeit bills by cloning and altering bills, which not only caused heavy economic losses to the country, but also affected the stability of the financial order. Among the counterfeit bills, ordinary bills (such as tax bills) have become the main forgery objects, but since the anti-counterfeiting digital is only printed on the surface of the paper, it is easy to be forged, so the original inquiry digital anti-counterfeiting label can no longer adapt Management identification requirements for the current ticket. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present inven...
