Crayfish and ceramic works have ID cards
to know where they come from
Changjiang Daily News (Reporter Lei Xinrui Correspondent Wang Wenhui) At the end of April, the first batch of crayfish went on the market.
On April 24, a reporter from Changjiang Daily came to the farmers' market. Baskets of crayfish that had just been salvaged were weighed in front of the sorting table, packed and sent to various markets in Wuhan.
In fact, the food quality and safety management element data of these crayfish from breeding to sale are recorded by the industrial Internet platform.
The industrial Internet platform is the scientific and technological achievement of the scientific research project "Food Industry Internet and Quality and Safety Intelligent Management" jointly completed by Datang Internet Technology (Wuhan) Co., Ltd. and Huazhong Agricultural University.
Realize intelligent management of crayfish food quality and safety.
According to the production process, each batch of crayfish has its own "identity card".
"The information of the place of production and storage will be reflected in the serial number," said He Ningbo, chief engineer of Datang Internet.
The project has completed the national scientific and technological achievements appraisal.
The project has been authorized 14 invention patents, 25 software works, and formed 4 sets of technical specifications.
He Ningbo said: "The crayfish industrial Internet platform has established 18 kinds of hazardous substance detection and identification technologies, which can quickly and accurately identify substances such as heavy metals and harmful organic substances. For the operation, transportation, storage and other processes, the platform has formed a whole industry chain safety prevention and control technology system , developed 6 technical regulations and standards."
Six years ago, Datang Internet was still a small and medium-sized enterprise mainly selling German Siemens industrial software. In just a few years, the company has grown into a "specialized and new" small giant and invisible champion enterprise focusing on independent research and development. .
Another news (reporter Qiao Chi correspondent Zhu Sufang Pan Yuxiang) In the digital economy era, how many steps does it take to identify the authenticity of a ceramic work?
It's very simple, just take out your phone and scan the code.
In Jianghan District, an enterprise in the field of digital economy uses blockchain and microcode technology to put "hidden" anti-counterfeiting labels on ceramic works, so that ordinary consumers can also become "appraisal experts".
On the 24th, at the Huazhong Blockchain Technology Integration Innovation Center (hereinafter referred to as "Huazhong Chain Innovation Center") located in "Jianghan Innovation Valley", a reporter from Changjiang Daily saw a set of "Dehua mutton fat jade white porcelain" from Dehua, Fujian. suit".
The reporter picked up a white teacup to observe and found that the mystery was hidden at the bottom of the teacup.
The bottom of the teacup in the reporter's hand is "Star New" in 4 small cyan characters, and below the bottom is a square microcode composed of countless gray dots.
The microcode is integrated with the base model. If you don't look closely, it is difficult to find that these small dots are irregularly arranged.
Wang Qing, head of Huazhong Chain Innovation Center and chief engineer of Hubei Posts and Telecommunications Planning and Design Co., Ltd., introduced that microcode is a customized microscopic and macro intelligent image recognition system based on a huge database of patented algorithms. The diameter of a single code point is only 30-60 A micron is about one-half the size of a human hair.
Compared with the current common two-dimensional codes and barcodes, microcodes have the technical characteristics of "one code for one item, ignoring damage, and concealed coding", making it extremely difficult to copy and forge.
"It's equivalent to giving each item a unique 'digital ID'."
"Because of the immutability and openness of blockchain, manufacturers need to be responsible for their own identification results. Once fraud occurs, it will become a 'stain' that can never be erased, thus losing market trust." Wang Qing explained.
Using the decentralized features of the blockchain, it can also access management nodes such as industry and commerce, public security, etc. in the identification process to establish an honest digital environment and produce additional effects.
For ordinary collectors or consumers, the identification process is very convenient.
Just open the dedicated WeChat applet and scan the microcode at the bottom of the teacup to view detailed information such as the name of the work, origin, material, craftsmanship, and producer.
