Abstract

The invention provides a dot-matrix graphic formed by ink dots with a microscopic characteristic. The dot-matrix graphic formed by the ink dots with the microscopic characteristic comprises an ink dot group with a microscopic characteristic, wherein ink dots a in the ink dot group have an irregular shape, and the top surface of each ink dot a is in a smooth structure or a texture structure. The method for distinguishing the dot-matrix graphic authenticity comprises the following steps: obtaining the image of a current dot-matrix graphic; when the ink dots in the dot-matrix graphic have the microscopic characteristic, analyzing the ink dots into the coded data of the dot-matrix graphic; distinguishing the coded data of the dot-matrix graphic in a database; extracting an information file corresponding to the coded data of the dot-matrix graphic; and outputting the information file. According to the dot-matrix graphic disclosed by the invention, the microscopic characteristics of the ink dot group with the microscopic characteristic and the ink dot group without the microscopic characteristic can be obtained only by an identification device with a microscopic identification effect, and the microscopic characteristics of the ink dots can not be obtained by an identification device without the microscopic identification effect. Therefore, the anti-counterfeit effect of the dot-matrix graphic is better than the anti-counterfeit effect of a conventional dot-matrix graphic.

Description

technical field

[0001] The invention relates to an anti-counterfeit mark, especially a dot matrix pattern, especially a dot matrix pattern composed of ink dots with microscopic characteristics and a method for distinguishing its authenticity. Background technique

[0002] like figure 1 As shown, the ink dot b3 in the existing dot matrix pattern 1 is generally composed of circular ink dots or square ink dots with the same shape. Although the positions of the ink dots are obtained through related algorithms, better anti-counterfeiting effects cannot be achieved because the ink dots have a single shape. Contents of the invention

[0003] In view of the deficiencies in the above problems, the present invention provides a dot matrix pattern composed of ink dots with microscopic features in various forms and better anti-counterfeiting effect and a method for distinguishing its authenticity.

[0004] In order to achieve the above object, the present invention provides a dot pat...
