Description

Technical Field

[0001] The present invention relates to a method and system for generating special-shaped labels with anti-counterfeiting functions, belonging to the field of anti-counterfeiting. Background Art

[0002] The fast recognizability and relatively large information storage capacity of two-dimensional codes have made them an anti-counterfeiting identification technology and advertising means widely used. People only need to hold a mobile phone to scan a two-dimensional code to obtain the people, organizations, or APPs associated with the two-dimensional code or the information it identifies, and then carry out relevant activities and applications. There are various forms of two-dimensional codes, such as QR codes composed of black and white squares, Dotcodes composed of circular code points, dot matrix codes, etc. At present, the manifestation forms of two-dimensional codes are relatively single, and there is a need for a two-dimensional code that can meet people's personalized anti-counterfeiting needs.

[0003] Existing methods for personalizing two-dimensional codes, such as CN109558927 "A Method and Device for Generating Artistic Two-Dimensional Codes", disclose the following steps: Step 1, generate the original two-dimensional code array of the two-dimensional code; Step 2, set and store the picture of the constituent element module of the artistic two-dimensional code; Step 3, perform binarization processing on the picture of the constituent element module to obtain the two-dimensional code array style of each picture of the constituent element module, thereby establishing the mapping relationship between the picture of the constituent element module and the two-dimensional code array style; Step 4, according to the mapping relationship, replace the two-dimensional code array style in the original two-dimensional code array with the corresponding picture of the constituent element module to form an artistic two-dimensional code. The disadvantages are: it is necessary to manually design a variety of element module pictures to meet personalized needs, and the color printing production cost is high and the time consumption is long.
