Description

[0001] The present application is a divisional application of application number "202210371686.X", filed on April 11, 2022, and entitled "Intelligent Rose Color Block Multi-Chaotic Pattern Encryption Anti-Cracking Anti-Counterfeiting Technology". TECHNICAL FIELD

[0002] The present application belongs to the field of anti-counterfeiting encryption algorithms, and specifically relates to an intelligent Rose color block multi-chaotic pattern encryption anti-cracking anti-counterfeiting method. BACKGROUND

[0003] There are many types of anti-counterfeiting technologies at home and abroad, which can be divided into two categories in terms of form: content anti-counterfeiting and form anti-counterfeiting. Content anti-counterfeiting refers to the fact that the product itself is not reproducible, and generally relies on special monopoly technology to complete the anti-counterfeiting function, which is expensive and rare. In contrast, form anti-counterfeiting, the anti-counterfeiting carrier appears on the product or the packaging of the product, is more widely used in daily necessities, and has more practical research value.

[0004] In terms of technology, form anti-counterfeiting has several more mainstream anti-counterfeiting technologies: one is the more traditional material label anti-counterfeiting technology, such as the commonly seen special ink label, laser engraving label, etc.; another is the use of two-dimensional code as an anti-counterfeiting technology carrier, combined with intelligent mobile devices and background databases to achieve the purpose of querying anti-counterfeiting; the third is the relatively new electronic tag technology, such as the previously widely used M1 chip label and RFID chip label, etc.

[0005] Two-dimensional code, as an information storage technology that replaces bar code, can quickly identify and record high-density data in limited space. For example, the invention patent "CN104240093A - A two-dimensional code anti-counterfeiting method" discloses a two-dimensional code anti-counterfeiting method, which specifically sets a unique two-dimensional code for each product, and corresponds the special string or number string in the two-dimensional code with the IMEI number of the mobile phone to realize that the unique verification code of the product is bound with other mobile phones, thereby being able to verify the authenticity of the product and achieving the purpose of anti-counterfeiting. The existing two-dimensional code technology includes PDF417, QR Code, etc. The existing scheme generally uses RSA asymmetric encryption algorithm for encryption inside the two-dimensional code, and then generally uses optical scanning of intelligent mobile terminals for identification, provides decryption algorithm by the internal software APP of the mobile terminal, and obtains the key online through the background database. However, this scheme has a natural technical defect. The optical visual requirement of two-dimensional code identification makes the anti-counterfeiting carrier itself provide the possibility of being reproduced, and the mobile terminal device used for identification cannot distinguish it, so that both the encryption method of external request and the security algorithm of two-dimensional code itself lose effectiveness, and therefore there is a great security risk in using this technology alone as a means of anti-counterfeiting and traceability.

[0006] From the daily use, the characteristics of the two-dimensional code are V1-V40, and the specific number is 40^10^10000. Now, human society consumes hundreds of millions of two-dimensional codes every day. With the progress of science, the improvement of full-intelligent batch code scanning technology will lead to the day when all two-dimensional codes are consumed. Once half of the consumption is reached, the anti-counterfeiting label with two-dimensional code as the carrier will fail. SUMMARY

[0007] The purpose of the present application is to provide a single anti-counterfeiting technology to multiple anti-counterfeiting technology integration, further integration of traditional anti-counterfeiting technology and information anti-counterfeiting technology, information technology, emerging material technology, intelligent identification technology, biological identification technology, process refinement, etc. from the development and application trend of anti-counterfeiting technology. Anti-counterfeiting technology innovation is an active field. The integration of anti-counterfeiting and Internet+, big data will make anti-counterfeiting technology and production services, consumer services more closely integrated, and gradually transition from single anti-counterfeiting verification to comprehensive services such as anti-counterfeiting traceability and logistics management. In addition to realizing the anti-counterfeiting function, it can also trace the source of raw materials, factory time, place, circulation channel, end consumer, etc. of the product. Technical progress and innovation-driven will open up space for the development of anti-counterfeiting industry. The development of future anti-counterfeiting technology will certainly take the identification method as the goal, which is convenient, high in imitation and transfer cost, and low in deployment cost.

[0008] The "Ross color block" described in the present application refers to a color block unit based on RGB color space, which is valued by a specific algorithm and supplemented by a Russian block type splicing form. The "intelligent Ross anti-counterfeiting code" refers to a graphical code with high anti-counterfeiting strength generated by the above Ross color block unit and the integration of multiple encryption algorithms (such as chaotic encryption, base conversion, invisible security lines, etc.).

[0010] To achieve the above object, the present application provides the following technical solutions: the intelligent Ross anti-counterfeiting code is an ordered encrypted pattern anti-counterfeiting code formed by multi-encryption of intelligent RGB fixed value block digital pattern, the anti-counterfeiting code of the agreed pattern is mixed and verified based on the database by twice specifying the agreed number, the agreed value becomes an edited agreed specific one-dimensional code / two-dimensional code data center module, the image encryption technology of chaotic image is used to twice specify the absolute value of the image data stream, the agreed mixed 2-128 binary code of the two-dimensional code and the encrypted pattern is spliced and synthesized, and then the image encryption technology of cloud limited value segmentation and secret directional value is used to segment the spliced image into multiple quadrant blocks, the RGB value (0.0.0)-RGB value (255.255.255) intermediate value is color limited and a certain binary value and the agreed color block are associated by specifying the data on the cloud, the basic color matching algorithm is used to color each block, and the invisible agreed line encryption technology can be superimposed in the specified area of the label, the multi-encryption technology is used to produce the intelligent RGB fixed value block digital pattern multi-agreed encryption anti-counterfeiting label, and the multi-anti-counterfeiting encryption technology can be associated with each other and independently analyzed. The basic color matching algorithm is an algorithm for allocating corresponding colors to the segmented quadrant blocks according to the RGB and binary association rules agreed on the cloud.

[0011] As a preferred embodiment, the ordered encryption pattern anti-fake code formed by the intelligent RGB value block digital pattern multi-encryption is a one-dimensional code or a two-dimensional code, characterized in that the anti-fake code is multi-encrypted in the cloud by the intelligent RGB value block digital pattern, the data packet can be sent to the cloud by the intelligent device to perform reverse identification decryption on the anti-fake code, the RGB value block is provided with a conventional code encryption conversion table for setting the generation rule of the computer color block, and the CMYK code conversion can be performed according to the conversion table during printing code conversion, the CMYK code conversion is a multi-encryption type conversion mode, and the encryption conversion table can be mixed and sorted for multi-encryption according to the date of use of the anti-fake code.

[0012] The above scheme is used to realize the color conversion means of multi-encryption, and the differences between cmyk and rgb are explained.

[0013] 1. The nature of the two is different: RGB is the color displayed by the display, and CMYK is the color used for printing. If the display is used for previewing CMYK, the color will change. 2. The two are different in the medium they are aimed at: RGB is the best color displayed by the display, and there will be deviation problems when the display displays in CMYK mode; when printing in RGB, the color will also have deviation. 3. The two are different in meaning: RGB mode is a color mode based on three primary colors of light. RGB image only uses three colors, and when unequal amounts of three color lights are superimposed and mixed, various colors in nature will be reproduced on the screen. CMYK is a 4-color printing ink: cyan, magenta, yellow, and black (here, the last letter K is used instead of the first letter B to avoid confusion with blue). The encoding method is different, resulting in RGB mode when printing, but CMYK mode when printing, and there is a certain difference between colors. The decryption mode appears double decryption rule, and the encryption mode is according to the specific number obtained by adding the date of six digits as the corresponding addition position, and the corresponding digit position is located according to the month. The date is a conventional number sequence of the binary number, and the conventional table is added as a color deception form. The date is a binary cycle number of the deception digit, that is, even if the color rule is cracked, the hacker cannot get the limited table relationship and cannot crack the anti-fake code content. The change logic will be explained in the form of a table:

[0014] RGB to CMYK;

[0015] R' = R / 255;

[0016] G' = G / 255;

[0017] B' = B / 255;

[0018] K = 1 - max(R', G', B');

[0019] C = (1 - R' - K) / (1 - K);

[0020] M = (1 - G' - K) / (1 - K);

[0021] Y = (1 - B' - K) / (1 - K);

[0022] CMYK to RGB;

[0023] R = 255 * (1 - C) * (1 - K);

[0024] G = 255 * (1 - M) * (1 - K);

[0025] B = 255 * (1 - Y) * (1 - K);

[0026] The color chart corresponds to the color control group, which can be calculated by color computer. The fraudsters cannot identify the color quadrant of the chart without the control chart. The setting rules can be changed according to the needs.

[0027] The relationship between CMYK, corresponding number of digits, and calculation logic of fraudulent number sequence;

[0028] For example, on December 16, 2021;

[0029] The corresponding additive number is 21 + 12 + 16 = 49;

[0030] The corresponding number of digits is 12;

[0031] The corresponding base number is 16;

[0032] The following data is obtained when 0.0588, 0.0275, 0.0 (12th true number) 000, 0.0000:

[0033] 49 (decimal) = 31 (hexadecimal);

[0034] 0.0588, 0.0275, 0.31 (12th false number) 000, 0.0000;

[0035] The following chart shows an example of the logical relationship between true numbers and false numbers:

[0036]

[0037]

[0038] As a preferred embodiment, the color change of the individual small color blocks of the anti-counterfeit code can have 1678 million color changes according to the agreed code encryption conversion table, there are 100 to 10000 small color blocks on each anti-counterfeit code, and the small color blocks have 1678 million 10000 times of permutation and combination order, i.e. the anti-counterfeit code has a combination of 1.678x10^7^10000 at most, and the probability of occurrence of two identical anti-counterfeit codes is Infinity, and the repetition probability is lower than 10^-70000.

[0039] Using the above scheme, color mixing encryption means is realized, each color block is distributed in different shapes, distribution is taken as count number 1, and color is taken as count number 2. The following color block mode can be obtained, three blocks become an RGB count mode, and an example of using Russian square block patterns is shown in a chart form:

[0040]

[0041] As a preferred embodiment, the anti-counterfeit code based on the database mixes and verifies the secondary specified numbers of the agreed pattern, and the feature lies in that the mixed verification is a one-dimensional code and a two-dimensional code pattern formed according to the positioning logic of the specific mixed color blocks calculated by the power multiplication of the agreed code encryption conversion table.

[0042] Using the above scheme, the generation mode of the two-dimensional code has a new random square pattern formed by the color corresponding to the above cheating algorithm.
