Embodiment Construction
[0038] 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.
[0039] An embodiment of the present invention provides an anti-counterfeit element, the anti-counterfeit element may include: a substrate, the substrate has a first surface and a second surface opposite to each other; and one or more A dense magnetic region, the dense magnetic region includes a plurality of sub-magnetic regions. The dense magnetic region refers to a small interval between any two adjacent sub-magnetic regions, and the small interval may be less than or equal to 0.4 mm. Under the condition that the minute interval is satisfied, the sub-magnetic regions may be arra...

The embodiment of the invention provides an anti-counterfeiting element and an anti-counterfeiting product, and belongs to the anti-counterfeiting field. The anti-counterfeiting element comprises a base material, wherein the base material is provided with a first surface and a second surface which are opposite as well as at least one or a plurality of dense magnetic areas which are formed on the first surface, the dense magnetic areas comprise a plurality of submagnetic areas, the spacing between two adjacent submagnetic areas in the plurality of submagnetic areas is less than or equal to 0.4mm, and different magnetically encoded waveform information which respectively correspond to a first magnetic sensor and a second magnetic sensor can be formed in the condition that the anti-counterfeiting element is detected by respectively using the different first magnetic sensor and second magnetic sensor. According to the anti-counterfeiting element, anti-counterfeiting classification is realized, the anti-counterfeiting information of the anti-counterfeiting element can be preferably concealed, and the anti-counterfeiting performance is improved.
Description
technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to an anti-counterfeiting element and an anti-counterfeiting product. Background technique [0002] Valuable documents such as banknotes, stocks, stamps, checks, air tickets, ticket labels, etc. are usually equipped with anti-counterfeiting components, which can ensure the authenticity of the information carrier and can also be used to prevent illegal copying. [0003] Magnetic materials are widely used in the anti-counterfeiting field, and a magnetic security thread is a particularly important application form of the anti-counterfeiting element, and the security thread is completely or partially embedded in banknotes. The magnetic sensor in the banknote processing system can detect the code sequence, thereby judging the authenticity of the banknote, and can also sort the banknote at the same time. [0004] The patent EP0310707A2 applied by Mantegazza Company proposes a method of...
