Machine learning technology-based intelligent seal impression recognition and anti-fake method

Abstract

The invention discloses a machine learning technology-based intelligent seal impression recognition and anti-fake method. The method comprises the following steps of: obtaining original seal impression data and data acquired during sealing by an intelligent impression anti-fake database; carrying out image acquisition on a to-be-detected impression in a limited area and carrying out preprocessingto obtain a naked impression; carrying out matching verification on naked impression data comprising seal specification information and the original seal impression data to obtain a weight value of the seal specification information; carrying out matching verification on feature data of a to-be-detected impression content view and the data acquired during the sealing so as to obtain a weight valueof the impression content view; carrying out matching verification on feature data of a to-be-detected background content view and the data acquired during the sealing so as to obtain a weight valueof the background content view; and carrying out weight add operation on the obtained weight value of the seal specification information, weight value of the impression content view and weight value of the background content view, and judging whether the impression is true or not through a total weight value so as to achieve the aim of rapidly verifying whether the seal is true or not.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting identification of seals, in particular to an anti-counterfeiting method for intelligent identification of seal texts based on machine learning technology. Background technique [0002] In our country, the seal is an important certificate to prove the identity of party and government agencies, enterprises, social organizations and other organizations, and to represent 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 technology and quality of seal making have been continuously improved, the technology of counterfeiting seals has also been continuously improved. The crime of counterfeiting seals has become the same as that of guns and drugs. Crime has also become a major pu...

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 grea
