[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a DNA anti-counterfeiting coding system based on UTF-8 and 8 bases, which has the following advantages and effects:

[0021] 1. High anti-counterfeiting performance: Due to the use of UTF-8 encoding and the combination of 8 bases, the encoding system of the present invention has a higher information storage capacity and a more complex pairing relationship, making forgery and tampering more difficult. At the same time, the use of a variety of different base combinations to represent different characters and information further increases the difficulty of forgery.

[0022] 2. High accuracy: The detection method of the present invention has high sensitivity and high specificity, and can accurately detect the DNA anti-counterfeiting label embedded in the product and parse the UTF-8 encoding information therein, thereby realizing accurate identification of the authenticity of the product.

[0024] 4. Low implementation cost: Although the coding system of the present invention uses a combination of UTF-8 and 8 bases, the implementation cost is relatively low because the bases are prepared by chemical synthesis or biosynthesis. In addition, the detection method of the present invention also has the advantages of easy operation and low cost. At the same time, due to the use of the universal UTF-8 encoding, it can be easily compatible and interactive with other information systems. DETAILED DESCRIPTION

[0025] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods.

[0026] Example 1

[0027] A DNA anti-counterfeiting coding system based on UTF-8 and 8 bases combines UTF-8 coding with 8 bases to form a new coding system. In this system, each character is represented by UTF-8 coding, and the specific information of each character is represented by a specific combination of 8 bases. This combination can improve the complexity and security of the coding. Specifically, for example, the detailed information of the item is "Moutai Prince Liquor, produced by Guizhou Prince Liquor, the 4th batch produced in 2024, October 26, 2024". This is the encoding content that requires UTF-8, which is generated by the binary coding of the computer. This information is translated into a combination of 8 bases through the coding system. First, define the correspondence between the 8 bases and binary, such as UTF8_TO_BASE:Dict[str, str] = {

[0028] 'A':'00', 'G': '01', 'C': '10', 'T': '11', 'dS': '000', 'B': '001', 'Z': '010', 'P': '011'}.

[0029] Based on the detailed information of the item, the binary value can be deduced, and then the relevant sequence can be designed based on the correspondence between the bases and the binary value.

[0030] 2. Design and synthesize 8 bases: Prepare 8 bases including A (adenine), C (cytosine), G (guanine), T (thymine), S, B, Z, and P through chemical synthesis or biosynthesis, ensuring that each base has a specific chemical structure and physical properties. These bases are achieved through chemical reactions or enzymatic reactions. In order to increase the difficulty of counterfeiting, a variety of different base combinations can be used to represent different characters and information.

[0031] 3. Construct DNA anti-counterfeiting labels: embed specific sequences in the coding system combining UTF-8 and 8 bases into the product as anti-counterfeiting labels. DNA anti-counterfeiting labels can be realized by automated DNA synthesizers to ensure the accuracy and purity of the sequence. In order to improve the anti-counterfeiting performance, a variety of different DNA sequences can be used as labels, combined with complex coding rules to increase the difficulty of counterfeiting. DNA anti-counterfeiting labels are synthesized according to the coding system combining UTF-8 and 8 bases. DNA anti-counterfeiting labels can be marked with fluorescent groups or biotin.

[0032] 4. Detection and analysis of DNA anti-counterfeiting labels: Detect and analyze the DNA anti-counterfeiting labels embedded in the product through specific detection methods (such as fluorescence scanning or direct sequencing). Specific methods include:

[0033] (1) Extracting DNA from the product: Using an appropriate extraction method, such as a DNA extraction kit, to extract the embedded DNA fragments from the product;

[0034] (2) Amplification and detection of DNA: The extracted DNA is amplified using PCR technology using a PCR amplifier, and then the amplified product is detected using a specific detection method (such as fluorescence detection, electrophoresis, etc.);

[0035] (3) Parsing UTF-8 encoding: According to the detected DNA sequence, parse out the UTF-8 encoding information contained therein;

[0036] (4) Authenticity Identification: The authenticity of the product is determined by comparing the parsed UTF-8 encoding information with the specific encoding rules. If the parsed information is consistent with the expected, it is judged to be authentic; if the parsed information is inconsistent or cannot be parsed, it is judged to be a counterfeit.

[0037] Example 2 High-end wine anti-counterfeiting

[0038] In the high-end wine market, the problem of counterfeiting and fake products has always been serious. In order to protect the brand image and consumer rights, the DNA anti-counterfeiting coding system of the present invention can be used. The specific steps include:

[0039] 1. Design and synthesize a specific combination of 8 bases to represent the unique identification code of alcoholic products;

[0040] 2. Combined with UTF-8 encoding, a unique DNA anti-counterfeiting label is generated for each alcoholic product;

[0041] 3. During the production process, the DNA anti-counterfeiting label is embedded into the wine bottle or wine cap, or it can be embedded by pasting or hanging with a rope;

[0042] 4. When consumers purchase, if they have any questions, they can send the product to the laboratory for testing. Through specific detection methods, extraction (such as DNA extraction kit extraction) and detection of DNA anti-counterfeiting labels (such as sequencing methods), the UTF-8 encoding information can be parsed to confirm the authenticity of the product.

[0043] Example 3: Luxury Goods Identification

[0044] The luxury goods market is also a hard-hit area for counterfeit and fake products. In order to protect consumer rights and maintain brand image, the DNA anti-counterfeiting coding system of the present invention can be used. The specific steps include:

[0045] 1. Design a unique 8-base combination for each luxury product to represent its identification code;

[0046] 2. Combined with UTF-8 encoding, a unique DNA anti-counterfeiting label is generated and embedded into the product;

[0047] 3. During the identification process, the DNA anti-counterfeiting label is extracted and tested, the UTF-8 encoding information is parsed, and compared with the genuine database to confirm the authenticity of the product.

[0048] Example 4 Drug Safety Tracing

[0049] In the pharmaceutical market, in order to prevent counterfeit and inferior drugs from entering the market and ensure the safety of patients' medication, the DNA anti-counterfeiting coding system of the present invention can be used. The specific steps include:

[0050] 1. Design a unique 8-base combination for each drug to represent its identification code;

[0051] 2. Combined with UTF-8 encoding, a DNA anti-counterfeiting label containing information such as drug production and circulation is generated and embedded in the drug packaging;

[0052] 3. By detecting and analyzing DNA anti-counterfeiting labels, the production and circulation of drugs can be traced to ensure the safety and authenticity of drugs. At the same time, consumers can also confirm the authenticity and quality of drugs by querying the parsed UTF-8 encoding information.

[0053] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art can use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention still belongs to the protection scope of the technical solution of the present invention.
