Problems solved by technology

However, in low-precision printing, such as printing with a precision below 200dpi, each dot matrix has exceeded the size invisible to the naked eye calculated by the Rayleigh criterion. Into the effect? How to achieve anti-counterfeiting effect while embedding information? This will be the problem to be solved in this patent application

Embodiment Construction

[0114] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are illustrative rather than limiting.

[0115] In the following description of this embodiment, the dot matrix is ​​the smallest unit constituting a two-dimensional barcode, which is composed of a number of printing dots, and the printing dot is the smallest unit that can be printed by a printing device.

[0116] The definition of the two-dimensional barcode in the present invention: it is a computer graphic code that can describe information and has certain decorative characteristics.

[0117]Definition of information description module: It is an integral part of the information description of the two-dimensional barcode. Generally, a two-dimensional barcode is composed of several information description modules. When the two-dimensional barcode contains only one information description module, the two-dim...

Abstract

The invention relates to a novel anti-cracking method of a two-dimensional barcode in the field of information processing. Cracking the code content and illegally reading the code can improve the security of the code and the effectiveness of anti-counterfeiting. It is also suitable for low-precision printers. While printing the printed image, a large amount of information is embedded through various patterns and texts, so that The printed image is beautiful, and at the same time, the embedded information will not be copied, so as to realize the anti-counterfeiting effect of goods and tax stamps, thereby completely solving the problems of bill forgery, tampering, and commodity counterfeiting spreading in society, and promoting the harmonious development of society.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to an anti-cracking method of a two-dimensional barcode. Background technique [0002] With the rapid development of our country's economy, the application and development of barcode technology has attracted the attention of various fields such as tax stamp anti-counterfeiting and commodity anti-counterfeiting. [0003] The bar code was first invented by a graduate student of the business department of Harvard University in the United States. The original idea was that the customer selects the product he needs through the product list, and takes the corresponding card printed by the punch card machine to the pick-up window. You can get the desired goods. Stores can use this card to correct inventory, or as an application form to charge customers. As such an advanced logistics method, it was not popularized due to the excessively low labor force at that time. Nowadays, barcod...
