Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] As we all know, magnetism has polarity, and magnetic lines of force are generated between the two poles of NS. See Figure 1A , 1B . It can be seen from the figure that as long as the position of NS is different, the direction of its magnetic force line is different. Figure 1A The magnetic lines of force are distributed horizontally, Figure 1B The magnetic field lines are vertically distributed. According to the principle of electromagnetic inducti...

Abstract

The invention discloses a negotiable security anti-counterfeiting detection method and device. The negotiable security anti-counterfeiting detection method comprises the steps of utilizing a magnetic sensor to obtain sensing voltage of a negotiable security in at least two directions, enabling any two directions of at least two directions to be mutually perpendicular, determining the direction of a magnetic force line on the negotiable security according to the sensing voltage, judging the authenticity of the negotiable security according to a comparison result of the direction of the magnetic force line on the negotiable security and the direction of a pre-saved magnetic force line. By means of the negotiable security anti-counterfeiting detection method, the authenticity of the negotiable security can be judged according to the direction of the magnetic force line. Compared with a detection method based on wrong magnetism in the prior art, the anti-counterfeiting detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of anti-counterfeit detection of valuable securities, in particular to a detection method and device for detecting the authenticity of valuable securities based on the direction of magnetic force lines of the valuable securities. Background technique [0002] Magnetic anti-counterfeiting is one of the basic methods of anti-counterfeiting means for securities. Usually, a certain area (image) of securities is printed with magnetic ink or a magnetic barcode is made on a metal wire. According to this characteristic, the counterfeit detector is equipped with a magnetic sensor to detect the magnetic area (magnetic barcode) of the securities, and judge whether there is magnetism on the securities, so as to judge the authenticity of the securities. [0003] However, such methods can only detect a part of counterfeit documents, namely those without magnetic features. For those counterfeit securities with magnetic features, th...
