Anti-counterfeiting coding method and decoding device

Abstract

The invention discloses an anti-counterfeiting coding method. The method comprises the following steps of: (1) setting a coding device for generating an anti-counterfeiting graph, and performing coding through the coding device by using the existence state of element points printed by using a special invisible material and position information thereof in an anti-counterfeiting graph array as coding information factors; (2) inputting coding condition data through a computer system connected with the coding device, automatically performing calculation according to the set conditions and the coding rules through a coder to obtain the numerical values of element codes, and automatically generating anti-counterfeiting audio or images according to the numerical values; and (3) outputting the generated anti-counterfeiting audio or images. The invention also provides a decoding device for implementing the method. When special elements are detected, the numerical values of the codes are calculated according to the arrangement of the element points, and the purpose of management is further fulfilled.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to an anti-counterfeiting coding method, and more particularly to a decoding device for realizing the method. Background technique [0002] Barcodes are divided into two types: one-dimensional barcodes and two-dimensional barcodes. One-dimensional barcodes are composed of a set of regularly arranged bars, spaces and corresponding characters, which represent certain information. The main feature of a two-dimensional code is to represent data information in both horizontal and vertical directions. Representative two-dimensional codes include PDF417, QR code, etc. Since the coding rules of one-dimensional codes and two-dimensional codes have been made public, at the same time, reading machines have also been released. Very mature, so security is relatively weak. In addition, the current barcodes are all visible to the naked eye, and copying and copying are very easy. Ther...

Problems solved by technology

The main feature of a two-dimensional code is to represent data information in both horizontal and vertical directions. Representative two-dimensional codes include PDF417, QR code, etc. Since the coding rules of one-dimensional codes and two-dimensional codes have been made public, at the same time, reading machines have also been released. Very mature, so security is relatively weak

In addition, the current barcodes are all visible to the naked eye, and copying and copying are very easy. Therefore, when they are used in the market, their confidentiality and security are very weak. Fields with high security requirements, such as important documents, tickets, certificates, securities, brand protection, etc., are very unsafe. How to use a technology that can retain the large-capacity and fast-readable QR codes? advantage, and overcome the weakness of poor security, there is no relevant technology disclosed and implemented
