Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, first use the code generator (Version 3.6) to generate a variable character string "123456789", and import this variable character string "123456789" into the variable information "National Tax Levying Branch Printing No. 22, 2011* Number *2011.11.04*", and save this variable information as a variable information text document;

[0020] Input the pre-encrypted information "encrypted information of a certain company" into the encryption program "Coal Aviation Security Printing Encryption Management Software", and then perform calculations with the random encryption key (KEY) "87654321" in the encryption program to generate encrypted information " lLGQLH11hK", and the separator "&&" is automatically added before the encrypted information to become "&&lLGQLH11hK"; at the same time, the key (KEY) is stored as a key text file, and the en...

Abstract

The invention discloses a multiple anti-fake method based on a two-dimensional bar code, and relates to the technical field of anti-fake printing. The multiple anti-fake method comprises the steps of: encrypting and decrypting pre-encrypted information by using a randomly-set secret key as taking the two-dimensional bar code as a carrier; and commonly storing the encrypted information and variable information. The encrypted two-dimensional bar code is printed through invisible anti-fake ink by using a digital ink-jet printer, and the obtained two-dimensional bar code has very strong anti-fake capability.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting printing and the field of two-dimensional barcode generation and recognition methods. Background technique [0002] Two-dimensional bar codes have been widely used in logistics, supermarkets, printing and other fields. This technology is a very promising automatic identification technology. It is receiving more and more attention from various industries and has become a research hotspot in the industry. Since the two-dimensional barcode itself does not have the function of confidentiality, the information contained in it is easy to be copied and deciphered on the Internet or other physical spaces. Contents of the invention [0003] The purpose of the present invention is to provide a multiple anti-counterfeiting method based on a two-dimensional barcode, which combines the two-dimensional barcode with variable information printing technology, computer encryption technology, and anti-...
