Problems solved by technology
[0002] At present, due to the improvement of computer image processing, laser engraving, laser scanning and printing technology, counterfeiting seals has become quite easy, and the counterfeit seals are also extremely realistic, and ordinary users cannot distinguish their authenticity, which endangers the security of financial institutions' bill business
Moreover, the existing seal management system and seal anti-counterfeiting technology are far from meeting the needs of seal management. The company's official seal filing information cannot be networked and shared with other government departments, and it is impossible to effectively supervise unregistered seals. Some illegal seals It has brought great harm to the market economy and the country, enterprises or individuals

Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.
[0019] The first embodiment of the present invention relates to an anti-counterfeit seal. like figure 1 As shown, the anti-counterfeit seal in this embodiment includes: a printing module arranged in the seal, a control chip for controlling the execution of the printing module, and a measurement module for detecting the posi...

The invention relates to a seal, in particular to a counterfeit-proof seal comprising a printing module arranged in the seal, a control chip and a measuring module. The control chip is connected to the printing module and the measuring module. Compared with the prior art, when the seal is used for stamping, the measuring module detects the position of the seal on the paper and uploads detected position signals to the control chip, and the control chip controls the printing module to print the position signal in a form of two-dimensional codes on the seal surface on the paper to form raster graphics according to the positioning signals uploaded by the measuring module; since any two seals with two-dimensional-code raster graphics can never be the same, the stamping position of the seal on the paper is unique and cannot be copied theoretically. Therefore, difficulty in carving an official seal illegally is increased; even through a criminal carved an official seal illegally, a user can determine the authenticity of the seal through a two-dimensional code scanner.
