Embodiment Construction

[0030] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.

[0031] An embodiment of the present invention provides a magnetic anti-counterfeiting element. The magnetic anti-counterfeiting element may include: a substrate; and at least a first magnetic coding sequence and a second magnetic coding sequence formed on the surface of the substrate, wherein the first The width of the nonmagnetic region in the magnetic coding sequence is smaller than the width of the magnetic region, so that the machine readable signal of the first magnetic coding sequence originates from the nonmagnetic region of the first magnetic coding sequence, wherein in the...

Abstract

The embodiment of the invention provides a magnetic anti-counterfeiting element and a magnetic anti-counterfeiting product, and belongs to the field of magnetic anti-counterfeiting. The magnetic anti-counterfeiting element comprises a base material, and the first magnetic coding sequence and the second magnetic coding sequence that are formed on the surface of the base material, wherein the widthof a non-magnetic region in the first magnetic coding sequence is smaller than that of a magnetic region, so that a machine-readable signal of the first magnetic coding sequence comes from the non-magnetic region of the first magnetic coding sequence; the width of a non-magnetic region in the second magnetic coding sequence is greater than the width of a magnetic region, so that a machine-readablesignal of the second magnetic coding sequence is derived from the magnetic region of the second magnetic coding sequence. The magnetic anti-counterfeiting element can realize phase modulation of waveforms of machine-readable signals, and has high anti-counterfeiting performance.

Description

technical field [0001] The invention relates to the field of magnetic anti-counterfeiting, in particular to a magnetic anti-counterfeiting element and a magnetic anti-counterfeiting product using the magnetic anti-counterfeiting element. Background technique [0002] Magnetic materials are an important carrier of machine-readable detection signals, providing sorting and anti-counterfeiting functions for banknotes, bills of exchange and other valuable securities. The machine-readable detection signal usually contains three aspects of information: shape, amplitude and phase of the detection waveform. The traditional magnetic machine-readable anti-counterfeiting technology is more about designing magnetic anti-counterfeiting elements from the perspective of detecting the amplitude and shape of the waveform, so as to upgrade the level of machine-readable anti-counterfeiting. [0003] For example, the patent EP0310707A2 can realize the change of the detection waveform amplitude ...
