Method and device for recognizing authenticity of seal

Abstract

The invention provides a method and device for recognizing the authenticity of a seal, and relates to the technical field of seal recognizing. The invention aims at providing the method and device fore remotely recognizing the authenticity of the seal. A client-side collects the pattern of the seal and the serial number of the seal, and uploads the pattern and the serial number to a server. The server finds out the copy image of the seal according to the serial number of the seal, and a system enters recognizing stages, wherein the recognizing stages include seal impression extraction, seal impression registration and authenticity recognizing. In the process of seal impression extraction, the seal impression is extracted through a PCNN burning technology, and the extracted seal impression is then repaired through a rapid advancing restoration algorithm. In the process of seal impression registration, the extracted seal impression is rotated and deformed, and the spatial location relationship of the extracted seal impression is adjusted to be matched with the copy seal impression. In the process of authenticity recognizing, authenticity recognizing is conducted by comparing the registered seal impression with the copy seal impression, the difference degree of the two images is calculated through a partitioning technology, and authenticity recognizing is conducted on the seal according to a set threshold.

Description

Technical field [0001] The invention relates to a seal recognition system in a mobile device and server mode, which can accurately identify the authenticity of the seal by relying on the seal data of the public security department, and specifically provides a true and false seal recognition device and a method thereof. technical background [0002] At present, my country's technology in seal management, seal anti-counterfeiting, and seal identification is not very mature. Driven by huge economic interests, criminals wantonly forge the seals of administrative agencies, law enforcement agencies, financial institutions, enterprises, institutions, and legal persons at all levels. , Causing huge economic losses to the country, collectives and individuals, posing a serious harm to social public security, and greatly undermining social credibility.

Problems solved by technology

[0002] At present, my country's technology in seal management, seal anti-counterfeiting and seal identification is not very mature. Driven by huge economic interests, criminals wantonly forge the seals of administrative agencies at all levels, law enforcement departments, financial institutions, enterprises, institutions and legal persons , caused huge economic losses to the country, the collective and individuals, constituted a serious hazard to social public security, and greatly undermined social credibility

[0003] Regarding seal recognition technology, although some people have studied it academically, it has not been put into specific applications, and the academic research content is basically limited to traditional image processing methods, the actual application effect is not very good, and the processing efficiency is low

At the same time, the academic method does not consider the original and copy of the seal separately, and the scope of application is limited
