The main functions include status display such as order review, contract review, and payment confirmation review. After all the work is completed, it enters the query stage. The enterprise must first start the service. The service provider will start the service and put it into operation. When the order has expired, the status will change to the service stop. When the stop order can be deleted according to the situation, the product database will be unlocked. Table and anti-counterfeiting code table are also deleted at the same time. The order and contract management unit provides to classify orders according to the status of the order. For example, when you choose to submit an order for review, the part that appears will be the part of submitting the order for review.

Further, in the step 3, according to certain coding rules, the anti-counterfeiting code is divided into three sections: front, middle and back, the encoding of the front section is obtained by the encryption algorithm of the anti-counterfeiting code, the middle section is a random code generated by the system, and the back section is encoded as Product number; the anti-counterfeit code has a total of 31 digits, which are 10 digits in the front code, 10 digits in the middle code, 10 digits in the rear code, and 1 digit in the verification code. The steps to generate the corresponding anti-counterfeiting code include:

Step 301: the previous code is obtained by the function x=f(y), y is the middle code, x is the previous code, both are 10-digit numbers, for example, y is equal to 1234567890, and the even digit is 24680;

Step 302: Find the corresponding value in the mapping table according to the even-numbered digit of y obtained in step 31, and replace the even-numbered digit with the corresponding value in the mapping table to obtain a new y, such as 24680 corresponding to in the mapping table The number is A8F4C, replace 24680 with A8F4C, then y is equal to 1A385F749C;

Mapping table:

1 2 3 4 5 6 7 8 9 0 9 A 7 8 6 f D. 4 B C

Step 303: convert the new y into a binary number, for example, 1A385F749C is converted into a binary number equal to 1101000111000010111110111010010011100;

Step 304: Swap the odd and even bits of the binary number, for example, after swapping the odd and even bits of the given example, it is 1110001011000001111101110101100011010;

Step 305: Swap even digits and odd digits and then convert to decimal. If the obtained decimal exceeds 10 digits, take the first 10 digits, and if it does not exceed 10 digits, fill in the front with 10 digits;

Step 306: The verification code is the remainder obtained by multiplying the middle two digits of the front code, middle code, and rear code by the key, and then dividing by 10. For example, the anti-counterfeiting code is 7883137400-12345678936-0201208010-6. The key is 123456, and the verification code is equal to (1*1+3*2+5*3+6*4+2*5+0*6)%10=6.

For example, if you inquire about the authenticity of a product, the system will feed back the authenticity information of the product and the product manufacturer; if you inquire about the unlock code of the product, the system will feed back the service information of the product’s unlock code; the query is not the anti-counterfeit two-dimensional graphic corresponding to the system Encoding, the system will feedback that the encoding rules are incorrect, beware of counterfeiting!

In the authenticity inquiry process involved in step 6, the background obtains the anti-counterfeit code provided by the user and performs the first screening according to the coding rules to exclude the anti-counterfeit codes not generated by the system. Through the first screening to enter the product database query, first check whether the query code or IP address has been added to the blacklist. The blacklist is mainly for users who inquire maliciously. If they are not in the blacklist, check whether they meet the query conditions. The same account number can only be queried once, and the product has not been unlocked.

In the process of obtaining the unlock password involved in step 6, after the background obtains the query code provided by the user, the first screening is carried out according to the coding rules to exclude the anti-counterfeiting code not generated by the system. Through the first screening to enter the product database query, first check whether the query number or IP address has been added to the blacklist. The blacklist is mainly for malicious query users. If it is not in the blacklist, check whether it meets the query conditions and whether the product has been unlocked. Then check whether the number or IP address of this query is consistent with the unlocked one. If they are consistent, the unlocking index code will be returned. If not, no result will be returned, indicating that the lock has been unlocked.

The voice query system involved in step 6 mainly queries the anti-counterfeiting code through self-service or manual service. The way of self-help is mainly to dial the hotline provided by the system to realize the functions of authenticity inquiry, unlock password acquisition and transfer to manual service according to voice navigation. When receiving a manual service call, enter the anti-counterfeiting code in the voice query system, click query to get the query result, and the result will be displayed below the edit box.
