A method for intelligent identification and anti-counterfeiting of stamps and imprints based on machine learning technology

Abstract

The invention discloses a method for intelligent identification and anti-counterfeiting of seal text based on machine learning technology, which comprises the following steps: obtaining original seal text data and data collected when stamping from a stamp text intelligent anti-counterfeiting database; Image acquisition in a limited area, preprocessing to obtain the bare print; matching and verifying the bare print data including the seal specification information with the original seal print data, to obtain the weight value of the seal specification information; view the content of the seal to be detected The characteristic data of the background content view to be detected are matched and verified with the data collected during stamping to obtain the weight value of the printed content view; the characteristic data of the background content view to be detected are matched and verified with the data collected during stamping to obtain the background content The weight of the view; do weight addition operation on the obtained seal specification information weight, seal content view weight, and background content view weight, and judge the authenticity of the seal through the total weight, so as to quickly verify the authenticity of the seal Purpose.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting identification of seals, in particular to an intelligent identification and anti-counterfeiting method of seal printed text based on machine learning technology. Background technique [0002] In my country, the seal is an important certificate to prove the identity of the party and government organs, enterprises, social organizations and other organizations, representing their rights and legal effects. Seals play an extremely important role in social, political and economic life. [0003] With the development of modern science and technology, especially the development of computer technology and laser engraving technology, while the seal making technology and production quality are constantly improving, the technology of forging seals is also increasing. Crime has become a major public hazard in society, and it is particularly urgent to study new seal anti-counterfeiting technology. ...

Problems solved by technology

[0009] The above-mentioned anti-counterfeiting technology itself has defects and cannot fundamentally solve the problem of counterfeit seals

On the one hand, the current methods of identifying printed texts in my country still mainly rely on empirical judgments. Due to the differences in the sealing conditions of the seal, including the complexity of the background of the document, the force of the seal, the amount and quality of the ink pad, etc., it will have a great impact on the seal image. In this case, it is not only difficult to manually compare the extracted stamped text with the original stamped text, but also the accuracy rate Low and extremely inconvenient, it is not conducive to the real-time identification of seals by the public. On the other hand, the development and application of high-simulation technology provides convenience for engraving counterfeit seals. Seriously disrupted the normal economic and social order
