Constituting method of novel two-dimensional bar code

Abstract

The invention relates to a constituting method of a novel two-dimensional bar code in the field of information processing. The constituting method is characterized in that a two-dimensional bar code can be constituted on a printing medium or a commodity in a printing manner or by a laser marking press by a low-precision printer or an ink-jet printer without damaging the printed images or influencing the appearance of the commodity. Meanwhile, the constituted two-dimensional bar code is anti-counterfeiting. Printed contents of tax receipts can be embedded in the bar code in the manners of characters, patterns and shading by the novel two-dimensional bar code technology for realizing functions of embedding content information and automatically reading tax receipts and restraining tax dodging and evasion without influencing appearances of tax receipts. Meanwhile, anti-copy performance and the identification of the tax receipts can be realized. Therefore, problems of counterfeiting and falsifying tax receipts and counterfeiting commodities are prevented from spreading in the society, and the harmonious development of society is promoted.

Description

technical field [0001] The invention belongs to the field of information processing, in particular to a method for forming a novel 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...

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
