Invisible code digital anti-counterfeiting printing technology

“One foot high and one foot high,” and unscrupulous counterfeiting plagued the managers of the bill industry. Ordinary bills (such as tax bills) adopt traditional special papers, and special forms of anti-counterfeiting means such as inks are no longer adapted to the requirements of current bill management. A digital anti-counterfeiting technology with higher technological content is of concern to users.

Digital anti-counterfeiting technology breakthrough in paper media

In the key technology of anti-counterfeit bills in our country, ink and paper are mainly used to achieve anti-counterfeiting. It is not only required to meet the needs of general public identification, but also to meet the governmental arbitration arbitrage role. Through the specificity and individualization of anti-counterfeiting information, it can accurately identify Authenticity. This is also the new concept of modern anti-counterfeiting, that is, the combination of front-line public anti-counterfeiting, second-line instrument identification and three-line expert intelligent identification and anti-counterfeiting, and takes the road of an integrated anti-counterfeiting technology.

The realization of anti-counterfeit on the paper of notes is an advantage of Apollo's anti-counterfeiting technology and a development direction of the anti-counterfeiting of notes, and is one of the most effective methods for fundamentally eliminating false notes. The screen coding technology (hereinafter referred to as invisible code) of Apollo Corporation in Tianjin is to realize the loading of personalization data of invisible codes on paper media, and can be realized in the existing printing environment.

We all know that in the existing anti-counterfeit printing technologies, they can usually be divided into explicit and implicit. Dominant: It means that consumers can distinguish between true and false with the naked eye or the temperature without using special tools. Recessive: Professionals use special tools to identify true and false. While solving consumer's naked eye recognition, how to meet the manager's audit identification, but not easy to be forged, so that counterfeiters can not bulk copy the bill. Provide auditors with information support for quality traceability, recall, and counterfeiting. At this point, Tianjin Apollo's screen coding (hereinafter referred to as invisible code) technology gives a perfect answer.

The details of the generation principle of this technology and the application of the printing environment are described below.

World's first information buried invisible code

What is the technology of the invisible code? In a word, the invisible code is the world's first information embedded code considering the characteristics of the printed screen. Hear information embedded code, we will certainly think of 2D barcodes. So what is the difference between invisible codes and 2D barcodes? Everyone knows that the printed matter is drawn through dots. But on the surface of the printed matter, we can't see these small dots, so if we change the geometric or physical shape of these small dots to record information without changing the gray value of the dots, It can be done without destroying the quality of the printed image. Instead of barcodes, information can be recorded in an invisible form. The invisible code is developed based on this idea. For example, by changing the positions of the dots, changing the direction, changing the shapes, or breaking the dots. Combined several adjustments, you can hide the information in the image. Different from the two-dimensional code, it is able to embed a large amount of information without specific space.

Solid technical patent barriers and the first to establish industry standards

Invisible code is a technology and product with a high degree of patent protection in the world and in China. Its code data can reach more than 300 trillion, and the code is not disclosed and managed internationally. So the code we provide to our customers is The unique code that represents each customer’s identity is extremely secure. And our patent barrier will make the application in this field more advantageous. So far, Apollo has applied for a total of 74 patents, 64 domestic Chinese patents, 7 domestic Japanese patents, 1 US patent, and 3 PCT patents.

As Apollo Japan has long served the world's top 500 companies, we have accumulated more than 10 years of work in patent protection. In the field of dot matrix codes for recording information in printed images, early Japanese Fuji Xerox proposed using single-bit information describing different directions of the lattice geometry, different shapes, different sizes, and different locations to enter the 2000 Ricoh of Japan. Having obtained a patent in a different direction, OKI Corporation of Japan obtained a description of the physics through different propagation directions. At the time, Apollo obtained geometrically patents for multi-bit information descriptions in different directions, different shapes, different sizes, and different location methods, as well as patents for recording information through different phase modulation methods, etc. In the area of ​​dot matrix code, even the world famous Swedish Anoto company and Japan’s Grid company’s patents are just a specific patent under different location patents that we propose and are limited by our patent. In particular, we use the invisible code to achieve digital anti-counterfeiting. We have exclusive patents in the world. In January 2008, the National Quality Supervision Bureau and the National Standardization Committee jointly approved the project and issued a plan for the development of a national standard for printers with a screen code as the technical core and technical requirements for the information security of the copier. The project has now been completed and completed in 2008. In September, it was published to the international printer and copy industry.
