In the digital economy era, how many steps does it take to identify the authenticity of a ceramic work? It's easy. Just take out your phone and scan. In Jianghan District, a company in the digital economy uses blockchain and microcode technology to label ceramic works as "hidden", allowing ordinary consumers to become "authentication experts".
'Digital ID card' hidden in teacup
The mystery of "blockchain + microcode" lies at the bottom of the teacup.
24, located in the "Jianghan Valley" central China blockchain technology fusion innovation Center (hereinafter referred to as "Central China chain innovation Center"), Yangtze Daily reporters saw a set of dehua suet jade white porcelain set from Fujian Dehua. The reporter picks up a teacup, white cup body is wen embellish like jade, simple sense is vigorous however connect fully, look be like with the teacup on market indistinct 2 send, and mystery criterion hides in teacup bottom money place.
Bottom style refers to the marking pattern made by the author on ceramic or other works of art after they are made, which is generally located at the bottom of the work.
Reporter hands the bottom of this teacup is "star new system" 4 cyan small characters, bottom bottom, is composed of countless gray dots square microcode. The microcode is integrated into the bottom, and it is hard to see the irregular arrangement of the dots unless you take a closer look.
Central China chain innovation center, Hubei post and telecommunications Planning and Design Co., LTD. Chief engineer Wang Qing introduced, microcode is based on a huge patent algorithm database, the formation of customized micro macro intelligent image recognition system, the diameter of a single code point is only 30-60 microns, about one half of a hair.
Compared with the current common two-dimensional code, bar code, microcode has the technical characteristics of "one thing one code, ignore damage, hidden coding", making it extremely difficult to be copied and forged. "Every item is labeled with a unique digital ID card."
Identification results are more reliable and transparent
Microcode has a certain anti-counterfeiting and true-checking function, but because the microcode comes from the manufacturer and the "authentication right" is also in the hands of the manufacturer, the credibility, transparency and objectivity of the identification results cannot be effectively guaranteed. The addition of blockchain technology solves this problem.
"Thanks to the imtamability and openness of blockchain, manufacturers need to be responsible for their identification results, because once fraud occurs, it will become a 'stain' that can never be removed, thus losing the trust of the market." Wang Qing explained. With the decentralized characteristics of blockchain, management nodes such as industry and commerce and public security can also be connected in the identification process to establish an honest digital environment and have additional effects.
For the average collector or consumer, the identification process is very convenient. You only need to open the special wechat mini program and scan the microcode at the bottom of the teacup to check the details of the work, such as name, origin, material, process and producer. On the digital certificate page, information such as collectors and circulation records are encrypted with unique codes, which can be traced back on the authentication service platform.
"Blockchain + microcode" has broad application prospects
Make on the surface of delicate pottery and porcelain false label, can affect quality and ornamental?
Wang Qing introduced that the link of anti-counterfeiting label and coloring process are carried out synchronously. Through the decoration technique of "glaze color", the ceramic itself is painted and microcode is fired together on the ceramic surface. After high temperature curing, microcode and ceramic integration, neither affect the quality, and not easy to wear.
It is understood that microcode has arbitrary plastic properties, in addition to square, can be made into arbitrary irregular shapes according to different needs. What's more, if special pigments are used, the microcode can be invisible to the naked eye, but it can be sensed by the camera of the phone, further enhancing the "invisibility".
The ceramic tea set, which uses "blockchain + microcode" technology, looks just like ordinary porcelain.
"We are now discussing cooperation with ceramic manufacturers in Jingdezhen to transform the technology as soon as possible." Wang Qing said that "blockchain + microcode" technology is not limited to ceramics, microcode applicable materials also include paper, PVC, glass, metal and other flat, curved and special-shaped materials, in tobacco, wine and tea, agricultural products, drugs, hazardous waste treatment and other industries and fields have broad application scenarios. "Microcode technology to achieve one thing one code, block chain technology to enable production process traceability, the combination of the two will help enterprises to protect the brand, control channel quality, achieve false rejection and credit."
