An anti-counterfeiting mark, an anti-counterfeiting system, texture particles for the anti-counterfeiting mark and a use method for the anti-counterfeiting mark

Abstract

The invention provides a random texture anti-counterfeiting mark, which comprises a carrier and a plurality of texture particles randomly distributed on a bearing surface. A non-contact surface of each texture particle comprises at least two visual color parts. Each visual color part presents respective visual color, so that at least one inclination angle exists, overall visual color formed by observing the plurality of texture particles at the inclination angle and overall visual color formed by observing the plurality of texture particles in the vertical direction vertical to the bearing surface have human-eye-recognizable visual color difference; and specific identification characteristics of the texture particles in the random texture anti-counterfeiting mark can be identified under the condition of not using an auxiliary tool, so that public participation is improved greatly. The invention also provides an anti-counterfeiting system adopting the random texture anti-counterfeiting mark, the texture particles for the anti-counterfeiting mark and a use method for the anti-counterfeiting mark; and same beneficial technical effects are obtained.

Description

technical field [0001] The invention relates to a random texture anti-counterfeiting label, an anti-counterfeiting system, texture particles used for the random texture anti-counterfeiting label and a method for using the random texture anti-counterfeiting label, belonging to the technical field of texture anti-counterfeiting. Background technique [0002] Texture anti-counterfeiting technology is an anti-counterfeiting technology that uses the inherent texture characteristics of the material itself as an anti-counterfeiting identification mark. An important feature of using texture distribution feature patterns for anti-counterfeiting identification marks is that each piece is different. The basic principle is to randomly form a texture. The distribution feature pattern is stored in the cloud database for further investigation, and the texture distribution feature pattern in the cloud database is called out for comparison during identification. If it does not match, it is fa...

Problems solved by technology

[0005] However, due to the tiny structure of the texture particles used to form the texture, it is difficult to directly judge whether there are specific identification features on the texture particles through public recognition methods such as direct recognition by human eyes or direct recognition by human eyes after taking pictures, so it is often necessary to use some Auxiliary tools (such as magnifying glass, special light source, etc.) are used to observe whether specific identification features are carried on the texture particles. It is difficult to accurately select the appropriate auxiliary tools, and these auxiliary tool identifiers are usually not carried with them, which greatly affects the public's participation in texture anti-counterfeiting technology
