Embodiment Construction
[0095] Such as figure 1 and figure 2 As shown, the present invention provides an anti-counterfeit label, which is composed of a matrix dot diagram mark with a dimension greater than 9, which includes an anchor point part 1 and a data point part 2, and the data point part 2 includes a function bit part 21 , data bit part 22 , checksum part 23 and raw feature extraction status part 24 .
[0096] Wherein, the function bit part 21 includes a version number flag point for representing a version number, an Mp algorithm type flag point for representing a data bit sparse processing algorithm type, a density value flag point for representing the number of valid data bits, The block index flag bit used to indicate the number of original code images in the anti-counterfeit label and the encryption algorithm type flag bit used to indicate the matrix point map identification encryption algorithm.
[0097] Such as image 3 As shown, the present invention provides an anti-counterfeit lab...

The invention provides an anti-counterfeit label. A data point portion comprises a function bit portion, a data bit portion, a verification sum portion, and an original feature extraction state portion. The function bit portion comprises a version number mark point bit, a Map algorithm type mark point bit, a density value mark point bit, a block index mark point bit, and an encryption algorithm type mark point bit. A method for generating the anti-counterfeit label comprises steps of: calculating the size of a memory cache Ap and the occupied quantity of data points; calculating the quantity of required filling characters and character information; distributing the quantity of effective data bits stored in a content cache Tp; arranging the filling data in the content cache Tp and encrypting the data; verifying the data bits and carrying out addition to the obtained data bits; carrying out sparse processing to the data bits so as to obtain a content cache Tp2; obtaining the data bits which the content cache Tp2 can bear, effective data bits and the quantity of the filling characters; writing information in the memory cache Ap; and transforming the data in the memory cache Ap, and implanting the transformed data in a blank grid. The anti-counterfeit label has a unique pattern and a large amount of data.
Description
technical field [0001] The invention relates to the field of labels, in particular to a matrix dot diagram mark, a generation method, a generation system and an anti-counterfeit label. Background technique [0002] At present, most of the existing anti-counterfeiting mark patterns are generated by using coding rules similar to OID coding technology, and only a limited number of anti-counterfeiting marks can be generated. Its disadvantages are: due to the small amount of coding information stored in the anti-counterfeiting label, it is impossible to store a large amount of data information; in addition, because the coding rules similar to OID coding technology belong to the general and open coding technology, the security of the anti-counterfeiting label is reduced. performance. Contents of the invention [0003] In view of the deficiencies in the above problems, the present invention provides an anti-counterfeiting label that can form a unique style and contains a large a...
