In today's society, paper is a very important information carrier. However, since the content on the paper is presented by printing, piracy and misappropriation are very embarrassing. Therefore, it is very necessary to conduct in-depth research on the embedding of information on paper. By means of digital means, the information of the paper is implanted into the paper inside the production process, so that the paper has better anti-counterfeiting characteristics.
Usually people use magnetic materials to characterize paper information. Although this method can effectively resist the breeding of imitation products in some aspects, most of these papers are made by post-printing methods. The characteristics of paper are on the surface, and the paper cannot be guaranteed. The uniqueness of information cannot fundamentally solve the problem of the expression of paper information, and these are all in the category of public recognition.
Paper embedded information digital implantation method
The method of implanting the internal information of the paper is designed to adopt a digital technology of fiber-forming process in the papermaking process, and utilize the advantages of the cellulose fiber to combine the magnetic fiber-containing composite fiber with advanced papermaking methods and control theory. The digital technology is used to invisibly embed “paper information” into the non-woven forming process, and the digitization technology is used to improve the uniqueness and reliability of paper function information digitization.
In the research of digital embedding of paper embedded information, a certain proportion of magnetic fibers are added to the fibers of the pulp, and the magnetic fibers are regularly interwoven by computer control technology, thereby achieving the purpose of digitally encrypting the paper.
In the pulping process, the magnetic fiber is uniformly mixed; the magnetic encoder is used to control the code to act on the magnetic fiber in the pulp flow, and the magnetic encoder is located above the mesh portion, mainly including a processor module, an input module, a storage module, and The conversion module, the input module is connected to the conversion module, and is used for inputting a decimal number. The conversion module and the storage module are connected to each other, and are used to convert the input digital number into 8421 code, and the processing module and the storage module are used together to control the magnetic code. The magnetic code of the bar code; the coding area of the magnetic coding controller is rectangular, the width is the width of the paper web, the magnetic strips are equally spaced in the coding area, and the magnetic encoder controls the magnetic properties of each magnetic strip by electricity, and the pulp flow When the control region is over-encoded, the magnetic fibers in the pulp gather around the magnetic strip (below the magnetic controller spacer) due to the force of the magnetic field, thereby forming a magnetic bar code inside the paper. The method completes the digital implantation of the embedded information of the paper under the condition that the pulp does not flocculate, and has obtained the patent authorization (patent application number is CN201210199190.5).
The method is further illustrated by the code "2016". The modern papermaking process includes pulping in the pulp pool, then forming on the wire section, drying in a drying cylinder, and repeatedly feeding, drying and feeding into the roll paper. Machine, the digital encryption method of the fiber-forming process, is based on the modern papermaking process:
First, in the process of pulping, add about 30% of magnetic fibers and mix them evenly;
Secondly, the net part is covered with a partition plate, and a slide rail is arranged along the flow direction of the pulp, and a magnetic code controller is arranged on the slide rail, and the magnetic encoder can move along the slide rail in the direction of the pulp flow; pulp When flowing through the code controller, the magnetic fibers in the pulp are subjected to the magnetic field and are gathered and formed according to the control code of the magnetic controller. The slide rail is adjusted so that the magnetic code controller is in the proper position of the net portion, and the coded wet paper web pulp after the forming is ensured. It does not deform before the dryer is dried, so a magnetic bar code is formed inside the paper.
The magnetic coding controller is placed above the network part and is composed of an input module, a conversion module, a storage module and a processing module. The input module is connected to the conversion module for inputting a decimal number; the conversion module is connected to the storage module, and the input digit is converted into 8421 code; the processing module is connected with the storage module for controlling the magnetic property of the barcode on the magnetic encoder.
The coding area of the magnetic coding controller is rectangular, and is equal to the width of the paper web. The magnetic strip is evenly distributed in the area, and a starting bit and a starting bit magnetic strip wider than other bits are arranged in the coding area to facilitate The width of the magnetic strip as the start position of the detection mark after the paper is wider than the magnetic strip of the other bits.
The mesh portion is covered with a partition plate, and the magnetic code controller is placed on the partition plate to prevent the slurry from being flocculated due to the action of the magnetic force when the magnetic encoder is operated.
The bar code formed by the magnetic fiber is inside the paper, and it is not easy to be seen or recognized in the appearance, and must be decoded by the corresponding magnetic stripe decoder to be recognized. In the process of encryption, the stored information is converted into 8421 code, so as to achieve the purpose of storing data information inside the paper.
Paper embedded information digital hardware design
In the fiber-forming process, a microprocessor-controlled magnetic encoding controller is used to complete the implantation of embedded digital information. The implant control system includes a keyboard input module, a storage module, a liquid crystal display module and a magnetic code controller module; the keyboard input module is mainly used for inputting system parameters, and the microprocessor converts the input numbers into coded data, the microprocessor and the storage module. Connection, on the one hand, can save relevant data, on the other hand, according to the information converted by the input module, control the on/off of the corresponding magnetic coil on the information coding controller. In the pulping process, the magnetic fiber is uniformly mixed. During the pulp flow process, the magnetic code controller is used to control the code, and the magnetic fiber is applied to the pulp. The magnetic encoder controller is disposed above the wire portion, and the magnetic encoder passes. The magnetic properties of each magnetic strip are electrically controlled. When the pulp flows through the code control area, the magnetic fibers in the pulp are concentrated around the magnetic strip by the magnetic field, so that a magnetic barcode is formed inside the paper, and the magnetic barcode is embedded in the paper. The conversion is easy and not easy to copy.
The research on the digital implantation of paper embedded information is a complicated problem. Although magnetic paper can effectively resist the breeding of imitation in some aspects, most of it is made by post-printing. The characteristics of paper are on the surface, ensuring The uniqueness of digitalization of paper function information is not possible. In order to enhance the reliability and uniqueness of digital identification of paper function information, digital identification of paper is carried out from the aspect of professional identification. This paper explores a digital implantation technology of paper function information, and proposes innovative ideas in the field of paper anti-counterfeiting.
