Fig. 2 is a schematic flow chart of a two-dimensional code verification method according to a preferred embodiment of the invention. The two-dimensional code verification method provided by the invention can be applied to the two-dimensional code verification system 10, the two-dimensional code verification method is executed by the two-dimensional code verification system 10, and the anti-counterfeiting authentication is realized by identifying and authenticating the color two-dimensional code carrying the target anti-counterfeiting information.
As will be described in detail below for each step of the two-dimensional code verification method shown in fig. 2, the two-dimensional code verification method provided in this embodiment may include the following steps:
step S400, the first electronic device 100 acquires a pre-generated color two-dimensional code carrying unique target anti-counterfeiting information;
in this embodiment, the color two-dimensional code may be generated by the server 200 according to the color two-dimensional code template based on the preset anti-counterfeiting information. The color two-dimensional code template can refer to fig. 3, and the color two-dimensional code can refer to fig. 4. In the anti-counterfeiting authentication process, the color two-dimensional code can be arranged on an object to be authenticated, wherein the object to be authenticated comprises but is not limited to retail commodities, product parts, takeaway and express items and the like.
Step S410, the first electronic device 100 extracts the number, the position distribution, and the RGB values of the color points in the color two-dimensional code, and determines the current anti-counterfeit information of the color two-dimensional code according to the number, the position distribution, and the RGB values;
in this embodiment, the first electronic device 100 may store a first anti-counterfeiting code associated with the number, and a second anti-counterfeiting code associated with the position distribution and the RGB values in advance. Step S410 may be: determining the first anti-counterfeiting codes related to the quantity according to the quantity, and determining the second anti-counterfeiting codes related to the position distribution and the RGB value according to the position distribution and the RGB value; and combining the first anti-counterfeiting code and the second anti-counterfeiting code according to a preset combination strategy, and taking the combined first anti-counterfeiting code and the combined second anti-counterfeiting code as the current anti-counterfeiting information. The preset combination strategy may be to splice the first anti-counterfeiting code and the second anti-counterfeiting code, wherein the first anti-counterfeiting code may be located before the second anti-counterfeiting code or located after the second anti-counterfeiting code.
Step S420, the server 200 obtains the current anti-counterfeit information from the first electronic device 100, and determines whether the current authentication is the first authentication;
step S430, if yes, the server 200 compares the current anti-counterfeiting information with the target anti-counterfeiting information;
step S440, when the current anti-counterfeiting information is the same as the target anti-counterfeiting information, determining that the verification is passed.
Understandably, if the color two-dimensional code is authenticated for the first time and the current anti-counterfeiting information is the same as the target anti-counterfeiting information, the server 200 determines that the authentication is passed. In addition, the server 200 may further send the result of the verification to the first electronic device 100, so that the user knows that the target to be authenticated corresponding to the color two-dimensional code is a genuine product and is not a counterfeit product.
Optionally, if the current authentication is not the first authentication, the method may include: the server 200 sends an authentication result characterizing the non-first authentication to the first electronic device 100. Based on the authentication result, the user can infer that the target to be authenticated is suspected to be a counterfeit.
Fig. 5 is a second flowchart of a two-dimensional code verification method according to a preferred embodiment of the invention. Optionally, before step S400, the method may further include step S450 to step S490, and step S450 to step S490 may be executed by the server 200 or the second electronic device 300, for generating the two-dimensional color code with the anti-counterfeiting information.
Step S450, the server 200 encrypts and generates M-bit first random numbers and N-bit second random numbers according to preset anti-counterfeiting information, and takes the preset anti-counterfeiting information as the target anti-counterfeiting information;
in this embodiment, the predetermined anti-counterfeit information may be a hyperlink with an anti-counterfeit code. The anti-counterfeiting code can be a numeric string or a character string or a combination thereof. The preset anti-counterfeiting information can generate M-bit first random numbers and N-bit second random numbers through an encryption algorithm, and the encryption algorithm can be selected according to actual conditions and is not specifically described herein.
Alternatively, the first random number and the second random number may be the same type of random number or different types of random numbers. For example, the first random number may be a random binary number, and the second random number may be a random binary number or a random decimal number. Of course, the first random number may also be a random decimal number. Here, the types of the first random number and the second random number are not particularly limited. M, N are positive integers, and the numerical values may be the same or different. For example, for binary number "1001", it can be regarded as a 4-bit random binary number.
Step S460, the server 200 determines the number of colored dots of the pre-generated two-dimensional code and the position distribution of the colored dots according to the M-bit first random number, where M is a positive integer greater than 1;
understandably, the pre-generated two-dimensional code is a color two-dimensional code which needs to be generated according to the preset anti-counterfeiting information. In this embodiment, the electronic device may store a color two-dimensional code template in advance, where the color two-dimensional code template includes Q pre-colored dots distributed in a preset shape, where the preset shape includes one of a square array distribution and a circular array, and Q is a positive integer.
Fig. 3 is a schematic diagram of a color two-dimensional code template according to a preferred embodiment of the invention. The pattern shown in the square line in fig. 3 is a schematic diagram of the color two-dimensional code template. The small circles in the square frame are pre-colored dots distributed in an annular array, the large circle in the center of the square frame can be used for a user to set a label, and the label can be used for advertising and propaganda.
Alternatively, step S460 may be: determining the number of the colored dots according to the numerical value of the M-bit first random number, wherein the number of the colored dots is less than or equal to Q; and selecting the pre-coloring points with the same number as the coloring points from the Q pre-coloring points, and taking the position distribution of the selected pre-coloring points as the position distribution of the coloring points.
And randomly selecting the same number of pre-coloring points as the number of the coloring points from the Q pre-coloring points by adopting a random algorithm. The random algorithm may be selected according to actual situations, and is not specifically described here.
Step S470, the server 200 selects a second random number corresponding to the number of the colored dots from the N second random numbers according to a preset selection policy, where each group of second random numbers includes P second random numbers, P is a positive integer greater than 1, and N is a positive integer greater than P;
the preset selection strategy comprises the following steps: and sequentially selecting P adjacent second random numbers from the N second random numbers according to a preset direction. The preset direction may be understood as a left-to-right direction or a right-to-left direction if the N second random numbers are arranged in a horizontal direction.
Step S480, the server 200 determines an RGB value of each coloring point according to the P bits of the second random number;
in this embodiment, the electronic device may store an association relationship between a random number and an RGB value in a one-to-one correspondence manner. Understandably, one color corresponds to one numerical value, so that colors can be obtained by numerical values, while different colors can be obtained by different numerical values.
Alternatively, step S480 may be: and determining an RGB value corresponding to the numerical value according to the numerical value of the P-bit second random number based on the incidence relation, and taking the RGB value as the RGB value of the coloring point.
In step S490, the server 200 generates a color two-dimensional code based on the number of the colored dots, the position distribution of the colored dots, and the RGB values of the colored dots.
In order to make the solution of the present invention more specific, the above solution will be specifically explained below.
For example, the first random number and the second random number may both be random binary numbers. Step S450 may be: and generating 256-bit binary number by a random number generator based on the preset anti-counterfeiting information. The first 64-bit binary number can be selected from the 256-bit binary numbers as the first random number, and the last 192-bit binary number can be selected as the second random number.
Step S460 may be: and determining the number and the position distribution of colored dots of the pre-generated two-dimensional code according to the 64-bit binary number. For example, the number of colored dots of the pre-generated two-dimensional code is determined according to the numerical value of the 64-bit binary number. And then selecting pre-coloring points with the same number as the determined coloring points from a pre-constructed color two-dimensional code template, and taking the position distribution of the selected pre-coloring points as the coloring point distribution of the pre-generated two-dimensional code. And the number of the determined colored points is less than or equal to the number of the pre-colored points in the color two-dimensional code template.
Step S470 may be: the binary number with the same group number as the determined coloring point number is selected from 192-bit binary numbers, and each group of binary numbers can be 3-bit binary numbers. The 192-bit binary number is not sufficient to form the same number of sets of binary numbers as the number of colored dots, and repeated selection can be made through the 192-bit binary number.
The server 200 stores in advance an association relationship in which binary values and RGB values correspond one to one. Step S480 may be: the selected value of the 3-bit binary number corresponds to the RGB value of a colorant (understandably, the RGB value is the color value representing the colorant), and different values represent different color values. According to the selected value of the 3-bit binary number, the RGB value of the coloring point corresponding to the binary number can be determined.
Step S490 may be: coloring the colored points thereof based on the number of the colored points, the position distribution of the colored points and the RGB values of the colored points to generate a colored two-dimensional code.
Based on the design, the color two-dimensional code is generated through double random number control, and the generated two-dimensional code is more unique. In addition, in the process of decrypting and reading the color two-dimensional code, the device for reading the color two-dimensional code needs to acquire the information carried by the color two-dimensional code after successful verification, so that the anti-counterfeiting function of the color two-dimensional code is improved. This scheme is through carrying out the identification authentication to the above-mentioned colored two-dimensional code that carries anti-fake information, helps improving anti-fake effect.
Fig. 4 is a schematic view of a color two-dimensional code according to a preferred embodiment of the invention. Understandably, fig. 4 is a gray scale diagram of a color two-dimensional code, that is, the pattern in the box in fig. 4 is a schematic diagram of a two-dimensional code obtained based on the above method. The small gray dots shown in fig. 4 are coloring dots, and the coloring dots with different gray levels correspond to different colors of the actually generated color two-dimensional code. In addition, the plurality of colored dots in fig. 4 are distributed in a ring-shaped array, and corresponding icons can be set in the central area of the two-dimensional code according to the actual needs of the user.
