Yangtze River Daily Wuhan client August 30 news (Yangtze River Daily reporter Qiao Chi correspondent Zhu Sufang) fingerprint unlocking, camera monitoring, real-time file archiving and uploading... After entering the era of digital economy, an enterprise in Wuhan has installed a wisdom brain for traditional seals through the use of the Internet of Things and blockchain technology, and cooperated with dedicated management applications and verification platforms to help enterprises effectively control seal management and use risks.
On August 30, a reporter from Changjiang Daily came to Jianghan Economic Development Zone and "unlocked" a new experience of using seals in the future at Hubei Post and Telecommunications Planning and Design Co., Ltd., which developed this set of "Hui Chain Cloud Signature" intelligent seal management platform.
Real-time supervision of the Internet of Things, the old seal "live in the safe"
In the Jianghan Economic Development Zone Huazhong Blockchain Technology Integration Innovation Center, the reporter saw at the scene that this modern smart seal is slightly smaller than the mineral water bottle, the shell is silver-gray plastic material, the top has a display screen, fingerprint unlock module and buttons, and the front is a camera and fill light, which looks full of science and technology, and it is completely impossible to see that it is a seal.

Wang Qing, chief engineer of Hubei Post and Telecommunications Planning and Design Co., Ltd., excitedly demonstrated to reporters the use of smart seals:
First press the finger on the fingerprint unlocking place, the built-in fingerprint chip almost instantaneously recognizes the identity information, and unlocks the seal; then, the sliders on both sides are pressed at the same time, and a circular physical seal is extended from the bottom and covered on the paper steadily; finally, the slider is released, the physical seal is put inside, and the device is automatically locked, and the whole process takes only a few seconds. In addition, the smart seal has an automatic ink extraction structure, and each stamp does not need to be dipped in the printing mud.

"After combing and analyzing various seal management scenarios, we have summarized the three goals of seal management, that is, 'the real seal should be managed well, the false account should be eliminated, and the multi-seal coordination should be coordinated'. At the same time of stamping, the camera will capture the content of the file, together with the identity of the person using the seal, the geographical location of the seal, the time of use of the seal, etc., through the built-in 4G Internet of Things card and security chip, encrypted and uploaded to the server. Wang Qing told reporters: In addition to fingerprint unlocking, the person with the seal can also unlock the seal through the password. If the unlocking time exceeds a certain time limit, the background system will also mark the stamp record as "abnormal", remind the administrator to verify the record, and prevent the risk of multiple covers and random covers in the process of using the seal.
"In fact, the 'Hui Chain Cloud Signature' smart seal is similar to a seal safe, which still uses the original traditional seal of the seal unit." Luo Zhang, product manager of the Blockchain Research Institute of Hubei Post and Telecommunications Planning and Design Co., Ltd., revealed to reporters: The smart seal adopts a universal seal structure and is suitable for almost all types of seals on the market.
To this end, the R & D team spent more than two months, bought more than 50 different types of seals for research, after repeated tests to find a solution for seal adaptation, "using our special fixtures, the use of smart seals will not destroy the seal body, nor do you need to re-engrave, directly load the original seal into the equipment." Luo Zhang said proudly.
The blockchain "leaves traces throughout the process", and all software and hardware are independently developed
It is understood that a complete set of "Hui Chain Cloud Signature" intelligent seal management platform is composed of intelligent hardware, supporting management applications, and blockchain verification platform. "Among them, the intelligent hardware device is jointly developed with the hardware manufacturer, while the supporting management application and the blockchain verification platform are completely independently developed by us." Mentioning this platform, Wang Qing's tone revealed pride.

"In the traditional stamping process, the signatories of the contract have difficulty verifying the authenticity of the sealed seal, and we have solved this pain point through blockchain technology." In the seal management application interface on the computer side, the reporter can see every stamp record of each smart seal, including the date, the person who used the seal, the seal number, the unlocking method, the address, the number of times the seal is used, the photo of the seal file and other details, and fully grasp the use process of the seal.
According to the SPC's Online Litigation Rules of the People's Courts, the scope of validity of blockchain depositories is stipulated for the first time, and the data stored on the blockchain has the effect of being presumed to have not been tampered with after being on-chain. The platform takes advantage of the immutable nature of the blockchain to effectively store certificates for the contract, solidify the electronic data generated during the signing process in real time, and provide a verification channel for the contract signatories through the public verification platform, and the signing parties are also "non-negatible".
"Smart seals have an extremely broad market, especially for some large enterprises with wide business distribution, smart seals can help them strengthen seal compliance management." Wang Qing introduced that since July this year, China Tongfu Hubei Company and its 16 subsidiaries have successively begun to use the "Hui Chain Cloud Signature" intelligent seal management platform. Up to now, the Hubei Tongfu seal management system has launched more than 50 smart seals, with an average of more than 2,000 new seal use records per day, and more than 50,000 seal use archiving records and on-chain depository records.

At present, Wang Qing and his colleagues have begun the research and development of version 2.0 of the "Huichain Cloud Signature" intelligent seal management platform. It is reported that the new version will further optimize the hardware equipment, improve the terminal coverage of the management system, and introduce blockchain smart contract technology, design a multi-party collaborative stamping process in accordance with different business specifications, realize the automatic verification of the seals of both parties and parties, and avoid the occurrence of false seals in the multi-party stamping process.
"The application of smart seals has played a leading role in promoting the development of the blockchain industry." According to the relevant person in charge of the Jianghan District Science and Technology and Economic Information Technology Bureau, the district is accelerating the construction of the Central China Blockchain Technology Integration innovation center and the Wuhan Blockchain Industry Innovation and Development Demonstration Zone, and the emergence of "Huichain Cloud Signature" is conducive to expanding the diversified application scenarios of blockchain and injecting scientific and technological strength into high-quality development.
