Anti-counterfeiting system and method adopting magnetic image

Abstract

The invention provides an anti-counterfeiting system adopting a magnetic image. The anti-counterfeiting system is used for detecting an object to be detected containing the magnetic image, and comprises a magnetic sensor and an image analysis module, wherein the magnetic sensor is used for scanning the object to be detected to obtain signals of the magnetic image in the object to be detected, and comprises a plurality of magnetic sensing units used for detecting the signals of the magnetic image in the object to be detected simultaneously; the image analysis module is used for receiving the magnetic image signals output by the magnetic sensor, and comparing the magnetic picture signals with a standard magnetic image signal to obtain a true / false result. The anti-counterfeiting system adopting the structure and the method can be used for high-level anti-counterfeiting through magnetic image detection.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting and security, in particular to a magnetic image anti-counterfeiting method and system. [0002] Background technique [0003] In daily life, magnetic security technology is widely used, such as bank cards, checks, confidential documents, banknotes, supermarket commodities and metal bars in libraries, etc., all contain magnetic materials for anti-counterfeiting and security. The existing magnetic security technology is for the use of The magnetic head roughly scans the part of the security area of ​​the object using the magnetic security technology to obtain a simple magnetic signal waveform and then check it with the standard signal to achieve the purpose of anti-counterfeiting and security. Such as a magnetic strip of banknotes, magnetic ink characters of checks, these relatively simple security graphics, with the improvement of counterfeiters' technology in recent years, forging simple magnet...

Problems solved by technology

Such as a magnetic strip of banknotes, magnetic ink characters of checks, these relatively simple security graphics, with the improvement of counterfeiters' technology in recent years, forging simple magnetic security graphics and magnetic strips has become a routine technology, it is not difficult to see that, The existing simple and rough magnetic security technology can no longer effectively achieve the security effect in the face of increasingly advanced counterfeiting technology
