Problems solved by technology

However, the thorny problem faced by commodity manufacturers is that in the process of commodity circulation, the non-uniqueness of the information labeling of the produced commodities makes it impossible to trace the commodities in the process of circulation. suffered huge economic losses
[0003] Therefore, how to prevent non-traceability and damage to signs in the process of commodity circulation, and how to solve the problems of flow-out and fleeing commodities in current circulation has become a problem of widespread concern to domestic and foreign scholars. At the same time, many solutions to the above problems have also been proposed. Among them, laser anti-counterfeiting, label anti-counterfeiting, ink anti-counterfeiting and other printing methods are the main ones. These traditional anti-counterfeiting methods are easy to forge and be damaged by human beings in commodity circulation, and cannot achieve effective anti-counterfeiting and counterfeiting effects.
[0004] However, for low-cost commodity packaging information printing anti-counterfeiting technology, there is no clear anti-counterfeiting and anti-interference solution based on discretized matrix information

Embodiment Construction

[0033] In the following, the three key steps in the technical solution of the method of the present invention will be introduced with emphasis on the accompanying drawings and examples, which will help to better understand the technical solution of the method of the present invention.

[0034] 1. Coding

[0035] like figure 1 shown , the shaded part is a 3*6 matrix table, and the cells surrounded by dotted lines are the result of folding each row and column of the matrix. Folding law like figure 2 shown :

[0036] Among them, Arabic numerals represent rows, Roman numerals represent columns, and ABCD is the result of turning the four corners of the table.

[0037] Now define each cell in the matrix table as follows:

[0038] (1) Randomly generate information bit 0 or 1 in the upper left corner of each cell, namely image 3 shown The square position in , thus generating the original matrix.

[0039] (2) The lower right corner of each cell is the check digit, namel...

Abstract

The invention provides an anti-interference matrix information encoding and decoding method for merchandise outer packaging, and relates to the circulation merchandise anti-counterfeiting tracing technology. According to the method, a discretization information encoding matrix is used as the unique unit packaging identity information, and data processing such as odd-even check, encoding, discretization, decoding and the like is conducted on the matrix information, so that information labels on circulation merchandises have the advantages of being unique, resistant to interference, large in capacity, traceable and the like. By the adoption of the anti-interference matrix information encoding and decoding method for merchandise outer packaging, on the one hand, traceability of the circulation merchandises is improved; on the other hand, decoding of the matrix information is facilitated, and query efficiency is improved.

Description

technical field [0001] The present invention relates to the field of anti-counterfeit traceability system for commodity information in circulation, and in particular to the data processing of information collection, information encoding and decoding process of commodity outer packaging in the anti-counterfeit traceability system, specifically refers to an anti-interference matrix information used for commodity outer packaging Codec method. technical background [0002] With the continuous development of the economy and the trend of marketization, the flow of trade is becoming more and more fast and convenient. However, the thorny problem faced by commodity production enterprises is that in the process of commodity circulation, the non-uniqueness of the information labeling of the produced commodities makes it impossible to trace the commodities in the circulation process. suffered huge economic losses. [0003] Therefore, how to prevent non-traceability and damage to sig...
