Description

Anti-counterfeiting tracing method and device for chemical fertilizer product

Technical Field

The application relates to an anti-counterfeiting tracing method and device for a chemical fertilizer product, and belongs to the technical field of anti-counterfeiting tracing of chemical fertilizer products.

Background

At present, the technical means of the chemical fertilizer industry for anti-counterfeiting tracing mainly comprises that a code with a self-defined format and a randomly generated tracing code are endowed to two-dimension code contents, and whether the tracing code is matched with a database or not is analyzed by identifying the two-dimension code so as to check the authenticity of the product. In most cases, the tracing code characteristics generated by each manufacturer can be basically divided into two types, namely 1 random generation disordered type; 2 ordered no encryption class.

Most of the current fertilizer enterprise product tracing codes are a group of specific digital codes which are generated in an unordered or random mode. The unordered tracing code and the random code are characterized in that the production information of the product, such as batch number and other information, is encrypted to regenerate the unordered tracing code, and the information of the generated batch and the like can be inquired after comparison through a central database.

The two types of codes do not contain production information, the existing tracing codes are easily counterfeited by fake manufacturers in batches or after analysis rules are carried out, so that the existing tracing codes are good in order, occupy the market of regular fertilizer enterprises, harm agricultural production and damage the benefits of farmers.

Meanwhile, in the fertilizer industry, the quantity of fertilizers in the same batch is large, the conventional tracing code only can display tracing information, the production sequence information of multiple bags of fertilizers cannot be acquired through the tracing code, the information utility is limited, and the method cannot be used for accurately managing a large number of single fertilizer products by enterprises.

Some ordered tracing codes do not have an anti-counterfeiting function, rules are easy to decode, and continuous batch change can be realized after decoding.

The method is characterized in that enterprise managers cannot directly and conveniently manage by tracing the appearance of the codes, and the method is disordered. For the fertilizer industry, product information cannot be efficiently identified after products are delivered from a warehouse. For example, when an enterprise uses an unordered traceability code to associate with a product, stacking product inventory, logistics shipping, enterprise marketing, etc. all introduce inefficiencies.

Detailed Description

The present application will be described in detail with reference to examples, but the present application is not limited to these examples.

According to the method, a provider generates continuous decimal traceability codes in batches through a traceability code registry according to the requirements of a production plan, performs many-to-one association on basic traceability information of similar products and stores the basic traceability information in a fertilizer traceability database. At the moment, the unique identification tracing code of each product has the characteristic of continuity, a unique digital check code is correspondingly generated through the encryption module according to each different tracing code, and the ordered tracing code is combined with the check code, so that the realized tracing code has the characteristics of continuity and non-batch counterfeiting.

The specific steps of the method provided by the application are described in detail in the following specific examples:

referring to fig. 1, step S100: and according to the requirements of a product production plan, generating ordered retrospective codes in batches before fertilizer production. And performing one-to-one correspondence association and binding on the product basic information and the ordered retroactive codes to form arrays, wherein each array comprises one product basic information and one ordered retroactive code. The generated array data is stored in a central database. And respectively endowing information such as production date, team and batch number of the specific product according to the number segments of the arrays.

For the off-line products, codes can be assigned to each ex-warehouse product in sequence according to the storage sequence of the tracing codes in the array, and the storage sequence corresponds to the ex-warehouse sequence. According to the operation, the method can be used for off-line products, and the application range of the method is widened.

When a packaging material is produced by a packaging plant of a fertilizer enterprise, the ordered tracing code is displayed in the form of the two-dimensional code, so that the advantage that the two-dimensional code can store a large amount of information is utilized, the ordered tracing code is associated with the network query website, and code scanning and source tracing are realized.

The two-dimensional code can be printed according to the self needs of enterprises. The ordered traceback codes can be displayed in the packaging material in a plaintext mode, and actual style enterprises can design the ordered traceback codes by themselves.

Step S200: the encrypted check code generation steps are as follows:

step S210: in the encryption module system, a group of character strings are obtained from a central database and are converted into a group of one-dimensional arrays with the length of 16 bits as encryption keys.

The resulting encryption key in this example is { -76, -23,2-65, -87,221, -76,64,98,43,12,87,34,23, -6,24 }.

Step S220: and judging the decimal retroactive code to be encrypted according to the number of digits of the coded decimal code, and if the length of the coded decimal code is greater than 32 digits, reversely intercepting the coded decimal code from the tail to 32 digits. If the length is less than 32 bits, a bit-filling operation is performed from the header to obtain a first code. The purpose is to convert the traceback code into a decimal code of length 32 bits.

The decimal code in this example is: 00000000000000000000125321526984, in this example, none of the previous 0 s have been complemented by the code added in the operation; the back 125321526984 is an ordered traceback code.

Step S230: and carrying out 16 times of circulation on the newly generated 32-bit decimal first code by taking the tail as the start, dividing the first code according to each array containing 2-bit numbers, wherein each array element is formed by adjacent two-bit decimal codes, and obtaining a code array with the array length of 16 bits.

The code set in this example is {00,00,00,00,00, 0012,53,21,52,69,87 }; the cycle here means that the division operation is performed 16 times to obtain 16 groups.

Step S240: each element in the array of the coding group is forcibly converted into byte type bytes, and the byte type bytes are arranged according to the original sequence to generate a message data group. This process is to reconstitute the code into one message data.

The message data in this example are: [0,0,0,0,0,0,0,0,0,0,97,81,2,81,54,81].

Step S250: and (3) mixing the message data with the encryption key obtained in the step (1), carrying out Hash encryption processing through 'HmacSHA 1' to obtain a first data result, carrying out Hash operation on the first data result and the encryption key again to obtain a Hash sequence, and converting the Hash sequence into a byte type array to obtain a second code.

As used in this example: the encryption key is { -76, -23,2-65, -87,221, -76,64,98,43,12,87,34,23, -6,24 }; the resulting hash sequence was 850cdac730aa27f8cd5dbdda1bb99e97b5ef2 adf; after this step, the second code obtained in this example is [ -13, -91,57, -39, -87,50,9,73, -22,12,120,74,3,49,100, -79, -85,112,86, -38 ].

Step S260: and from the end of the second coding array, sequentially intercepting the digit in reverse to obtain the check code. And intercepting the digit according to the length requirement of the encryption check code.

In this example, the check code is 4 bits, and the array elements of-85,112, 86 and-38 are taken as the check code sequentially from the end.

Step S270: and converting each array element in the check code into a binary system to obtain a third code. The third code can be used as an encryption check code.

The third code in this example is: -1010101; 1110000, respectively; 1010110, respectively; -100110.

Step S280: and according to the number of the complementary codes, carrying out a < <' left shift complementary code operation on each array element in the third code, and after the complementary codes are carried out, converting the obtained codes into a long integer data type. The number of the complement codes can be set according to the needs of users. In this example, the long integer data includes:

array element 1: -1426063360;

array element 2: 7340032, respectively;

array element 3: 22016;

array element 4: 218;

step S290: and adding the element values in the long integer data type to obtain a long integer code. In this example: the resulting long integer was coded as-1418701094. And intercepting according to the length requirement of the check code from the end of the long integer code, wherein the length of the check code is 4 bits in the example, the finally obtained encrypted check code is 1094, and if the long integer value is less than the length of the check code, the operation of 0 compensation is carried out at the front end of the long integer code.

Step S300: and setting the encrypted check code at the front end or the tail end of the ordered tracing code to obtain the anti-counterfeiting tracing code. And setting and generating the corresponding number of encrypted check codes according to the number of the ordered traceback codes. In this example, an encryption check code 6954 is added at the end of the ordered traceback code [615102014203 ]. Form an anti-counterfeiting traceability code [6151020142036954]

According to the method, after the basic information of the product and the encrypted secret key obtained by the ordered retrospective coding are mixed with the message data, the check code is obtained through a multiple Hash algorithm, and operations such as binary conversion, long integer data conversion and the like are carried out on each digit in the check code, so that the check code uniquely corresponding to the ordered retrospective code is obtained. After the check code is encrypted and operated in the step S260, the obtained third code is unique and can not be generated reversely, and external personnel can be effectively prevented from analyzing and cracking the check code in sequence. The confidentiality of batch products of the chemical fertilizer is improved, and the situation that counterfeit products flood the market and influence agricultural production is avoided.

2. The proposed sequential encryption tracing coding technology is not limited by any tracing coding length and characters. Enterprises can set by self according to self-defined coding formats, check codes obtained through an encryption and decryption system are unique no matter the length of the traceable codes, and the length can be adjusted at will.

3. The ordered encryption tracing code can be used for batch management in the enterprise distribution management tracing code, and the ordered batch correlation product information and the like are carried out according to the production batch, the product and the like when the tracing code is generated.
