detailed description

First, explain the basic terminology of this application:

1. Distribution image of the anti-counterfeiting label: The distribution images of the randomly distributed texture elements on the anti-counterfeiting label are different for each piece, and the combination can reach 10 or ²⁰ states without repetition, which is enough for all commodities in the world to use for 100 years without repetition, so the distribution image of the texture It is a non-repeatable code, and with the support of the digital image processing circuit, no code is required for the anti-counterfeiting mark.

2. The unlimited use rule of texture anti-counterfeiting: It means that the texture anti-counterfeiting technology will not affect the anti-counterfeiting effect after being used in a large number of product categories, which is determined by the principle of texture anti-counterfeiting. This is because the first random formation of texture distribution is a low-cost uncontrollable random process; while the anti-counterfeiting principle of traditional anti-counterfeiting is based on means such as unique equipment, unique technology, and technical secrets. Once a breakthrough is made, it will spread everywhere, thus Lose effect, based on this, traditional anti-counterfeiting technology can only ensure a certain anti-counterfeiting effect if it is effectively used.

3. Each anti-counterfeit mark also includes at least one code, the code on it corresponds to the anti-counterfeit mark 2 one by one, or the code on it corresponds to multiple anti-counterfeit marks 2; the function of the code is to address in the background and quickly call out Pre-stored features; where the code corresponds to multiple anti-counterfeiting marks is an important advantage that the code can be printed in batches with an ordinary printing machine, which is very efficient and low-cost.

4. The independent identifier and the image sensor in the external microscopic camera described in the utility model preferably adopt CMOS or CCD.

5. Distribution characteristics refer to the spatial position distribution of the texture formed in the random process, as well as the random orientation of the texture at this spatial position, the random rotation direction in multi-rotation directions, the random texture color in multi-color textures, etc., and are The recognizer is perceptible.

6. Inherent features refer to the physical characteristics of a single texture element on the anti-counterfeiting label, including the three-dimensional structure, color, and subtle color distribution on the texture of the texture element, which have nothing to do with the random distribution process.

7. To identify the inherent characteristics of texture elements, the purpose is to prevent counterfeiters from using low-cost controllable processes to imitate the texture distribution of genuine anti-counterfeiting labels so that the recognizer or human eyes cannot distinguish; the low-cost controllable processes in the prior art include various Various printing methods, various inkjet printing, including UV printing, 3D printing, various photolithography processes, etc.; in order to prevent such low-cost counterfeiting processes, especially for these The process texture structure design and the design-based magnification recognition method can make such a distinction, that is, the inherent characteristics of the recognition texture described in the present invention.

8. In order to realize the identification of the inherent characteristics of texture elements, in addition to the above-mentioned special design of the texture and the enlarged identification, a set of identification standards (instructions for enlarged identification) are proposed to inform the judges according to the characteristics of the existing technology that counterfeiters may use, especially In the recognition system, the discriminator can easily see and learn. The identification system includes anti-counterfeiting objects, anti-counterfeiting signs, identifiers, databases, backgrounds and the like.

9. Mobile phone. The mobile phone mentioned in this utility model usually refers to an existing smart phone without a built-in microscopic zoom camera. Generally, a mobile phone has two cameras, both of which are designed for ordinary landscape and portrait photography. Based on the optical lens, one lens cannot take into account the optical mechanism. Microscopic magnification and general photography, and the public demand for microscopic cameras are not yet strong, so existing mobile phones have not yet seen a mobile phone with a microscopic camera, especially a microscopic magnifying camera suitable for texture anti-counterfeiting identification.
