Problems solved by technology

According to the sampling method of texture anti-counterfeiting mentioned above, combined with the current specific application practice, it has the following serious defects: a, high anti-counterfeiting cost; b, too cumbersome query and verification; c, difficult to improve imitation
The fact is also the same. With the fiber texture in the currently used fiber paper, there are usually only 5 fibers as the anti-counterfeiting carrier. Cosmetics, etc. are very unsafe, because the fiber texture has the possibility of being reproduced by fine embedding by hand

Embodiment 1

[0017] Example 1, see figure 1 , the specific steps are:

[0018] 1. In the papermaking process, colored fiber is added to make fiber texture paper. The colored fiber consists of single red, single blue, single brown, single green, single black, single blue-red double-color segment, and single red-green Two-color, single red and black two-color segment and other fibers with obvious visual differences are mixed.

[0019] 2. Set the selection area (1) in the fiber texture paper, then divide the selection area (1) into 100 boxes (2), number the boxes (2) sequentially n, and set the interval for the boxes (2) as 1.5 mm coordinates (3);

[0020] 3. Code the products (5) on the fiber textured paper, and set a non-continuous and non-repeating number for each product and cover it.

[0021] 4. Print the query phone number or query website URL on the product;

[0022] 5. Select the position coordinates (a, b) of the end point (4) of a fiber arbitrarily in the box (2) that is numbere...

Embodiment 2

[0026] Example 2, see figure 1 , based on embodiment 1, its steps 1, 2, 3, 4, 7 are the same, and further features are:

[0027] 5. Define the color feature of the fiber in advance and number k, arbitrarily choose the position coordinates (a, b) of the end point (7) of a fiber in the box (2) with the number n selected, and record the root The color characteristic k of fiber, nkab is stored in computer database together as anti-counterfeit information and product code (5).

[0028] 6. When the inquirer inquires, according to the inquiring telephone number or the website address of the inquiring website, dial in the product code (5) by telephone or the Internet, and the computer database will answer through telephone voice description or short message description of mobile phone or online text, etc. When the product code (5) does not exist in the computer database, the answer is: "this query code does not exist, it is a counterfeit product"; when there is the product code (5) i...

Embodiment 3

[0030] Example 3, see figure 2 or image 3 , based on embodiment 1, its steps 1, 2, 3, 4, 7 are the same, and further features are:

[0031] 5. Use the very mature rapid real-time scanning and real-time printing technology to number the fibers in the selected area in advance. The method is to number the fibers in each box (2) according to 1, 2, 3... t; Select the position coordinates (a, b) of the end point (7) of a fiber in the square frame that selection is numbered arbitrarily, and record this root fiber number t and color feature k, use ntkab as anti-counterfeiting information and product code (5 ) are stored together in the computer database.

[0032] 6. When the inquirer inquires, according to the inquiring telephone number or the website address of the inquiring website, dial in the product code (5) by telephone or the Internet, and the computer database will answer through telephone voice description or short message description of mobile phone or online text, etc. ...

Abstract

The invention discloses an anti false method by using texture. The features are as follows. There are a lot of fibers in selected area; all fibers possess character of random distribution. Only one or few characters of random distribution are chosen as a carrier of anti false informatino to be stored on computer data for user to query through comunication method, so as to confirm whether the product is true or false. The characters chosen can be coordinate of an end point of one fiber or quantity of fibers in any local area for example. Although only one or few characters are chosen, since not knowing which one being chosen, falsifier must copy all distributed fibers in selected area accurately.

Description

technical field [0001] The invention discloses a texture anti-counterfeiting method, particularly an anti-counterfeiting effect equivalent to describing the entire texture by selecting only one or a few texture features as anti-counterfeiting information carriers and storing them in a computer database. Background technique [0002] The texture anti-counterfeiting method involved in the Chinese invention patent----structural texture anti-counterfeiting method (Application No.: 98116462.5) applied on August 8, 1998, which uses a camera to detect all textures in a defined selection area The information is fully stored, and then the verification information is provided to the inquirer in the form of a specific image by fax machine or the Internet, or by a cumbersome and extremely inaccurate voice description by telephone. According to the sampling method of texture anti-counterfeiting mentioned above, combined with the current specific application, it has the following serious ...
