It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

Referring to fig. 1, a method for filling anti-counterfeiting information according to an embodiment of the present application includes:

s1: and generating the two-dimensional code according to the anti-counterfeiting information according to a preset two-dimensional code rule.

The anti-counterfeiting information in this embodiment includes any information capable of generating a two-dimensional code, such as text password information, digital password, logo, and the like. The preset two-dimensional code rules are different according to different types of the anti-counterfeiting information, but at least comprise three parts, namely a two-dimensional code positioning pattern, two-dimensional code functional data and two-dimensional code data content, so that corresponding two-dimensional codes are generated according to the preset two-dimensional code rules. The two-dimensional code technology is similar to the existing two-dimensional code generation process, and is not repeated. The two-dimensional code of the embodiment can store more anti-counterfeiting information, and the integrity of the anti-counterfeiting information can be ensured by converting the anti-counterfeiting information into the two-dimensional code. The two-dimensional code has 40 sizes, the unit size is named Version, the two-dimensional code size and Version have a linear relation, for example, version1 is a matrix of 21×21, version 2 is a matrix of 25×25, each time one Version is added, the size is increased by 4, and the maximum value of Version is 40, so the maximum value of the two-dimensional code size is (40-1) 4+21=177, namely, matrix of 177×177.

S2: and acquiring an array corresponding to the two-dimensional code, wherein the array is formed by arranging a plurality of numbers.

According to the embodiment, the two-dimensional code is analyzed into the array consisting of binary digits 0 and/or 1, array ordering is formed according to the specified ordering rule, for example, the two-dimensional code is sequentially analyzed from left to right and from top to bottom, the black pattern in the two-dimensional code corresponds to 1, and the white pattern corresponds to 0, so that the two-dimensional code is analyzed into the binary number array.

S3: and hiding the numbers in preset pictures in sequence according to preset rules, wherein the preset pictures are pictures needing to be filled with the anti-counterfeiting information.

S4: and displaying a preset picture carrying the anti-counterfeiting information.

According to the embodiment, the numbers corresponding to the two-dimensional codes are sequentially hidden in the preset pictures according to the arrangement sequence, so that the hidden protection of the anti-counterfeiting information is realized. For example, the anti-counterfeiting information of the embodiment can form a corresponding two-dimensional code, and compared with the existing watermark anti-counterfeiting technology, the anti-counterfeiting information can be hidden in the preset picture and is not easy to perceive, the rights of the preset picture can be protected to the greatest extent, the anti-counterfeiting information is not easy to imitate, the preset picture added with the anti-counterfeiting information and the original preset picture are printed out and cannot be distinguished directly from the surface, and the anti-counterfeiting information is not easy to imitate and destroy. The preset pictures comprise product pictures, data pictures, contract document pictures and the like.

Further, the preset picture is formed by splicing a specified number of fragments, and the step S3 of hiding each number in the preset picture in sequence according to a preset rule includes:

s31: and sequentially judging whether the first fragments contain preset pixel areas according to a preset sequence, wherein the first fragments are contained in the specified number of fragments.

The preset picture in this embodiment is formed by splicing fragments, that is, the preset picture is divided into a plurality of small partitions by virtual fragments, and the number of the partitions is greater than or equal to the total number of the corresponding numbers in the array, so that the numbers and the fragments are matched one by one, the numbers are conveniently hidden in the picture in order, and the hidden array is convenient to manage. In this embodiment, the numbers are hidden in fragments containing the preset pixel area, fragments not containing the preset pixel area are not used for hiding the numbers, so that when the anti-counterfeiting information is analyzed, the corresponding hidden numbers are conveniently obtained by identifying the preset pixel area, the numbers are restored to the two-dimensional code, and the corresponding anti-counterfeiting information is obtained by analyzing the two-dimensional code. The preset pixel area comprises a pixel matrix with a specified size, and the pixel matrix contained in each fragment or most fragments can be satisfied, so that the purposes of hiding numbers through fragments and conveniently managing the hidden numbers are satisfied. Such as a 3×3 pixel matrix, a 5×5 pixel matrix, etc., the preset pixel area may be implemented in a preset manner.

S32: and if the first fragments contain the preset pixel areas, sorting the first fragments, and forming a first sorting according to the position of each first fragment in the preset picture and the preset sequence.

According to the embodiment, whether the preset pixel area exists in each fragment is judged sequentially according to the position of the first fragment in the preset picture through the preset sequence from left to right and from top to bottom, and if so, the fragments are counted into the first sorting so as to hide each number in the array sequentially according to the first sorting. The first sorting in this embodiment sorts the coordinate data of each first fragment in the preset picture, for example, the third fragment in the first row slice, which corresponds to the sequence number 3 in the first sorting; the fifth fragment in the first row slice corresponds to the sequence number 4 in the first order, and the third fragment in the first row slice is the coordinate data of the first fragment in the preset picture. The effect of the "first" in the "first fragment" is different from the "third" in the "third fragment", and the "first" in the "first fragment" is used for distinction only, and is not limited, and similar terms in other places have the same effect and are not repeated.

S33: and acquiring the sequence number of the first fragment in the first sequencing.

S34: and acquiring a first number in the corresponding sequence number in the array according to the sequence number.

According to the embodiment, the sequence numbers of the fragments in the first sequence are obtained, and then the one-to-one correspondence is formed according to the preset corresponding relation between the sequence numbers and the number sequence, so that the ordered hiding of the numbers is realized, the management and the extraction are convenient, and the reliability and the consistency of the anti-counterfeiting information are improved. For example, the preset corresponding relation is that the same direction sequence corresponds to the number ordering in the array one by one, namely, the number of fragments 1 to 100 is one by one from small to large, so as to form a first ordering; the number ordering is the number arrangement order formed from left to right in the array, namely the fragment numbers 1 to 100 form a first ordering, the number ordering in the corresponding array is 1 to 100, namely the 1 st number in the fragment hiding array with the fragment number 1, the 2 nd number in the fragment hiding array with the fragment number 2, and so on, so that each fragment is correspondingly hidden with one number. In other embodiments of the present application, the preset correspondence is a reverse order one-to-one correspondence to the number ordering in the array, that is, the sequence number of the fragments from small to large in the first ordering, one-to-one correspondence to the sequence number from large to small in the number ordering, that is, the number reverse order in the array is hidden in each fragment, so that the difficulty of acquiring the anti-counterfeiting information from the fragment is increased, and the difficulty coefficient of destroying the anti-counterfeiting information is improved.

S35: hiding the first number in a preset pixel area in the first fragment.

In this embodiment, the identification of different numbers is implemented by changing the pixel characteristic values of the corresponding preset pixel areas, for example, a full black pixel matrix with a designated size is selected, the identification number 0 is corresponding, some pixel points in the full black pixel matrix are changed to white, so as to correspond to the identification number 1, and all binary digits corresponding to the array are hidden in each fragment through the change rule of the pixel characteristic values. The fragments at least comprise one preset pixel area, and if the fragments comprise a plurality of preset pixel areas, the preset pixel areas arranged in the first sequence are selected as the preset pixel areas of the fragments according to the sequence from left to right and from top to bottom, so that a corresponding number is hidden. In other embodiments of the present application, the digital symbol itself may be photocopied to a preset pixel area to achieve hiding. For example, the pixels corresponding to the first palace lattice in the preset pixel area are changed from black to white, and the anti-counterfeiting information or the encryption information is photocopied on the first palace lattice in black fonts, wherein the first palace lattice is any one of all the corresponding palace lattices in the preset pixel area.

Further, before step S31 of sequentially determining whether the first tile includes a preset pixel area according to a preset sequence, the method includes:

and S30a, uniformly and parallelly cutting the preset pictures along a first direction according to a first preset interval to form a plurality of rows of pictures, and carrying out first coding on each row of pictures according to the row number of each row of pictures in the preset pictures.

And S30b, cutting each row of pictures along a second direction according to a second preset interval to form fragments, and performing second coding on each fragment according to the arrangement sequence of each fragment in the row of pictures, wherein the first direction and the second direction are mutually perpendicular.

And S30c, forming coordinate codes corresponding to the fragments respectively according to the first codes and the second codes.

The fragments in this embodiment are virtual partitions of the preset picture, i.e., the preset picture is virtually cut to form the partitions according to a preset rule. In this embodiment, the preset picture is divided into a plurality of rectangular partitions by line cutting and longitudinal cutting perpendicular to the line direction, and the row numbers of the lines and the longitudinal columns where the fragments are located are identified as the coordinate codes of each fragment, so that the fragments are spliced and directly restored into the preset picture by the coordinate codes. The first preset distance and the second preset distance are not limited by direct size relation, but the first preset distance and the second preset distance are kept unchanged during cutting, so that sequential and regular partitioning of preset pictures is realized.

Further, the preset picture is a text picture, the first preset interval is a line interval in the text picture, the second preset interval is a word interval between two adjacent words in the same line in the text picture, the line pictures are cut along a second direction according to the second preset interval to form fragments, and the step S30b of performing second encoding on the fragments according to the arrangement order of the fragments in the line picture includes:

S302: and cutting two adjacent characters from the first interval along the direction perpendicular to the rows to form fragments, and performing second coding on each fragment according to the sequence of each fragment in the row pictures.

The preset picture in this embodiment is a text picture, that is, the preset picture is a picture formed by text files, including text of a large paragraph. The first preset interval according to the line cutting of the embodiment is the line interval of the text. The second preset distance in this embodiment is the word distance between two adjacent words in the same row in the text picture, and each word in the text is correspondingly cut into fragments by line cutting and longitudinal cutting, so that uniform partitioning of the preset picture is realized, and the partition sizes are the same.

Further, the preset pictures are text pictures, the first preset interval is a line interval in the text pictures, the line pictures are cut along a second direction according to a second preset interval to form fragments, and the step S30b of performing second encoding on the fragments according to the arrangement order of the fragments in the line pictures includes:

s303: judging whether a second interval between two adjacent characters and a third interval in the characters are larger than the second preset interval or not;

s304: if the number is larger than the number, cutting two adjacent characters along the direction perpendicular to the row from the second interval, cutting the same character along the direction perpendicular to the row from the third interval, forming fragments, sorting the fragments in the row pictures according to the positions of the fragments, and performing second coding on the fragments.

In this embodiment, the second preset distance in the longitudinal direction perpendicular to the rows is smaller than the character distance of the text. In this embodiment, at the interval position larger than the second preset interval, longitudinal cutting is performed at the interval position, even if a spacing region larger than the second preset interval exists in the longitudinal direction perpendicular to the rows in the same word, the spacing region is also longitudinally cut, the cutting rule is hidden and is not easy to perceive, uneven partition of the preset picture is realized, the partition sizes are different, and the cutting rule is more hidden, for example, three to four fragments are corresponding after being longitudinally cut. For example, a certain line of text after line cutting is written as "center area limited company", and the fragments are formed by longitudinal cutting as one fragment corresponding to "middle", two fragments corresponding to "heart", one fragment corresponding to "area", one fragment corresponding to "have", two fragments corresponding to "limit", one fragment corresponding to "male", and one fragment corresponding to "span". The "heart" and "limit" are slit into two fragments from the spacer because the word includes a spacer larger than the second preset pitch.

Further, before the step S30a of uniformly and parallelly cutting the preset pictures along the first direction according to the first preset interval to form a plurality of rows of pictures, and performing the first encoding on each row of pictures according to the number of rows of each row of pictures in the preset pictures, the method includes:

s30d: judging whether the text of the anti-counterfeiting information to be filled is in a picture format or not.

S30e: if the text of the anti-counterfeiting information to be filled is not in the picture format, converting the file to be encrypted into the picture format according to a preset conversion mode to form the text picture.

The document to be encrypted in this embodiment is a document intended to pass anti-counterfeit filling anti-counterfeit information, for example, a text document such as a contract document, and the format of the text document needs to be converted into a picture format. If the text file is in a format such as Word or Excel, converting the text file into a picture format by a PDF conversion mode.

S351: and judging whether the first number is 1.

S352: and if the first number is 1, converting the pixel value of the central point of the full black pixel matrix into the pixel value corresponding to the white pixel to mark 1.

S353: if the first number is not 1, the first number is judged to be 0, and the all black pixel matrix is marked as 0.

In this embodiment, the preset matrix size is 3×3, the preset pixel area is a 3×3 full black pixel matrix, including a 9-grid distributed full black pixel area, and the fragments containing the 3×3 full black pixel matrix are fragments with hidden numbers. If the corresponding hidden number in the current number ordering is 1, the black pixel value of the center grid in the 9 grids is converted into a white pixel value, such as converting 255 x 255 into 0 x 0, the black pixel value is converted into a white pixel value. The identification and hiding of the numbers 1 and 0 are realized by changing the pixel characteristic values corresponding to the preset pixel areas.

Further, after step S3, hiding each number in the preset picture in turn according to a preset rule, the method includes:

The process of obtaining the hidden number from the fragment is reciprocal to the process of obtaining the hidden number, for example, whether a 3×3 full black pixel matrix or a matrix with a 3×3 center point being a white pixel value exists in the fragment is identified, if so, the discovery order is sequentially recorded as the arrangement order of the numbers in the array, the 3×3 full black pixel matrix is counted as the number 1, and the matrix with the 3×3 center point being the white pixel value is counted as 0. In the process of de-designating the two-dimensional code in this embodiment, symmetric encryption can be performed by AES (Advanced Encryption Standard ), so as to improve security. The process of acquiring the anti-counterfeiting information from the specified two-dimensional code has fault tolerance, and can still accurately acquire the anti-counterfeiting information under the condition that numbers within 30% are lost.

According to the embodiment, the two-dimensional code is generated by the anti-counterfeiting information, the numbers corresponding to the two-dimensional code are sequentially hidden in the preset picture according to the arrangement sequence, so that the hidden protection of the anti-counterfeiting information is realized. According to the embodiment, the numbers corresponding to the anti-counterfeiting information are hidden in fragments containing the preset pixel areas respectively, fragments not containing the preset pixel areas are not used for hiding the numbers, when the anti-counterfeiting information is analyzed, the corresponding hidden numbers are conveniently obtained through identifying the preset pixel areas, the numbers are restored to two-dimensional codes, and the corresponding anti-counterfeiting information is obtained through analyzing the two-dimensional codes. The first preset interval according to the line cutting of the embodiment is the line interval of the text. The second preset distance is a preset distance perpendicular to the longitudinal direction of the rows and is smaller than the character distance of the text. In this embodiment, the requirement that the spacing is larger than the second preset spacing is longitudinally cut at the interval, even if the spacing area which is larger than the second preset spacing exists in the same word and is perpendicular to the longitudinal direction of the line, the spacing area is also longitudinally cut, the cutting rule is hidden and is not easy to perceive, the uneven partition of the preset picture is realized, the partition size is different, the cutting rule is more hidden, the counterfeiter is not easy to extract the anti-counterfeiting information, and the counterfeiter is not easy to imitate or destroy.
