Table 1 below lists the meanings of all letter variables in the text.

letter code meaning m Product number T Product time information (year, month, day, hour, minute, second) D. Product Feature Information R relationship code B Product production date (year, month, day) b Product production time (hour, minute, second) o plain code C password K Security code

Table 1

The invention relates to an operation (fun) and three core data, namely product model information (M), product time information (T) and relationship code (R). For z=fun(x, y), it means that the binary code of z is equal to the bitwise XOR operation of the binary codes of x and y. In addition, x=fun(y, z), y=fun(z, x). In the present invention, M and T are determined when the product is produced, and written into the query authentication database. R=fun(M, T) provides the generation of the relational code, and R is the basis for the generation of the anti-counterfeiting code K. M=fun(T,R) and T=fun(R,M) provide the basis for query authentication: According to the previous formula, if K contains T and R, the product model M can be obtained through calculation; the latter formula is obtained After M, T can be calculated from R and M, and after obtaining M and T, it can be verified and compared with the information stored in the database to identify the authenticity.

In the embodiment of the present invention, let code represent an encoding operation; decode represent a decoding or hexadecimal conversion operation; "|" represent a connection operation, and A|B represent the connection of A and B characters.

(1) Product model: represented by the letter M, composed of several English letters. For example, the product model M of the product Dazhong Cigarette can be represented by DZH.

(2) Product time information: represented by the letter T, which can be accurate to seconds or even smaller time units, so as to ensure that no two or more products of the same model have the same production time. 14 decimal digits are available in the database, accurate to the second. For example, at 23:10:20 on December 30, 2014, T=20141230231020.

(3) Product characteristic information: represented by the letter D. D=M|T, where '|' indicates the connection operation, that is, the specific production time T of the connected product after the product model M. In the embodiment of the present invention, T is a 14-digit decimal number. Suppose M and T are as above, then D=DZH20141230231020.

(4) Production date of the product: indicated by the letter B. In the embodiment of the present invention, the year, month, and day of product production are taken to form an 8-digit decimal number, for example, B=20141230.

(5) Product production time: indicated by the letter b. In the embodiment of the present invention, the hours, minutes and seconds of product production are taken to form a 6-digit decimal number, for example, b=231020.

(6) Relationship code: the relationship code is represented by the letter R, which is a 31-bit binary number, calculated from M and T, and R=fun(M, T). The specific calculation process is as follows:

① Encode the product models M and T into 31-bit binary codes respectively;

a) Coding of product model M:

A codec correspondence can be established in advance, for example, when M=DZH:

code(M)=11111111111111111111111111111.

b) Coding of product time information T:

The specific encoding process of the product time information T is to encode the decimal numbers of the year, month, day, hour, minute, and second into their corresponding binary numbers. In the embodiment of the present invention, the year, month, day, hour, minute, and second are assigned binary digits of 5, 4, 5, 5, 6, and 6 digits respectively, representing the last two digits of the year 5 digits + the digits of the month 4 digits + 5 digits of the day + 5 digits of the hour + 6 digits of the minute + 6 digits of the second. The coding method for the product production date B and the product production time b is the same as the coding method for the product production date T.

In the embodiment of the present invention, the coding of the year adopts 5 binary numbers, which is to take the last 2 digits of the year and then binarize the remainder of 32, for example, the 5 binary numbers of 2001 and 2033 are the same; the coding of the month adopts 4-digit binary number representation, directly take the binary number of the month number, for example, the 4-digit binary number of December is 1100; the day is represented by 5-digit binary number, for example, the 5-digit binary number of the 30th is 11110; the time is 0-24 , the number of digits is 5 digits, for example, the 5-digit binary number at 23 is 100111; minutes are counted from 0-60 minutes, seconds are also counted from 0-60 seconds, and the digits are all 6 digits, for example, two digits of 10 minutes and 20 seconds The 6-bit binary number is 001010, 010100.

Therefore, if T=20141230231020, then the encoding of T (indicated by code) is:

code(T)=01110 1100 11110 10111 001010 010100.

② Perform bitwise XOR operation on the binary codes of M and T to obtain the 31-bit binary relational code R;

For example, the Great China Tobacco produced at 23:10:20 on December 30, 2014:

M=DZH, T=20141230231020

R=fun(M,T)=code(M)^code(T)

=(11111111111111111111111111111)^(0111011001111010111001010010100)

=1000100110000101000110101101011.

The embodiment of the present invention provides two schemes of the query authentication system, and the two schemes adopt their own forms of anti-counterfeit codes. Among them, the anti-counterfeit code of form 1 adopts the combination form of clear code and secret code, and the part of the code is covered with ink, and the anti-counterfeit code of form 2 is covered with full ink. Now take the Greater China Tobacco produced at 23:10:20 on December 30, 2014 as an example to describe each scheme in detail.

Fig. 1 shows that the present invention is based on the flow chart of the anti-counterfeiting method of product feature deformation combination and mutual authentication, and the specific implementation steps of the embodiment of the present invention query authentication system scheme one (using form one anti-counterfeiting code) include:

Step 1 shows and indicates the product model M (DZH) and product production date (2014.12.30) for each product in the product production stage, and writes the product feature information D (DZH20141230231020) of each product into the database;

The generation and printing of the anti-counterfeiting code in step 2 includes the following sub-steps:

(2-1) Anti-counterfeiting code generation:

Form 1 Anti-counterfeiting code K: It adopts the combination of plain code and secret code. The plain code part is represented by the English letter O, where O=M|B, which is formed by connecting the product model M and the product production date B; the secret code part is represented by the English letter C. C=decode(code(b)|R), which is a 12-digit hexadecimal number, and C is obtained by using a password generation algorithm. Fig. 2 is shown as the flow chart of generation algorithm of password (C) of the present invention, specifically comprises the following steps:

(2-1-1) Calculate the relation code R:

The calculation of the relation code R has been described above. In the embodiment of the present invention, R=1000100110000101000110101101011.

(2-1-2) According to the time coding rule, code the production time b of the product into 17-bit binary: b=231020, code(b)=10111 001010 010100.

(2-1-3) Combine the binary number obtained in step (2-1-2) and the relational code R into a 48-bit binary number and express it as a 12-digit hexadecimal number, which is the password C:

C=decode(code(b)|R)

＝decode(101110010100101001000100110000101000110101101011)

=B94A44C28D6B.

Fig. 3 shows the structural representation of the anti-counterfeiting code (K) of form one of the present invention, wherein K=M|B|C, promptly is made up of product model M and 8 decimal numbers and 12 hexadecimal numbers (product production The date B is 8 digits, and the password C is 12 digits). Therefore K=DZH20141230B94A44C28D6B.

(2-2) Anti-counterfeiting code printing:

Form 1 The anti-counterfeiting code K is presented in the form of a combination of plain code and secret code, the plain code part is O(M|B), and the secret code part is C. Both the plain code and the secret code must be printed on the product, but the part of the secret code must be covered with ink. For inspection and verification, the ink coating is scratched off and input into the system for authentication.

Step 3: Consumers inquire about authentication and information feedback. Figure 4 shows the flow chart of scheme 1 query authentication, which specifically includes the following sub-steps:

(3-1) Check whether the product model of the clearly coded part and the specific production date of the product are consistent with the product trademark and date spray code;

(3-2) Scratch off the ink coating covered by the password, and send the complete anti-counterfeiting code K to the official query system. The process of querying the system to authenticate the anti-counterfeiting code K=(M|B|C) is completed by two authentication links:

Certification 1 is to calculate M' based on the input B and C, M' is the calculated expected product model, check whether M' is equal to the product model M;

Authentication 2 is to extract the product feature D'=M'|T' in the input anti-counterfeiting code, T' is the calculated expected product time information, and query whether D' exists in the database.

If both answers are yes, the query authentication system will give the consumer the query result as genuine, and mark the record in the database to indicate that it has been queried; otherwise, feedback information to the consumer that the query result is false , and remind merchants of counterfeit products.

The calculation process of M', T' and D' in the above authentication 1 and authentication 2 is an analysis process of B|C. In the embodiment of the present invention, the anti-counterfeit code of Dazhonghua cigarettes produced at 23:10:20 on December 30, 2014 is: K=DZH20141230B94A44C28D6B, where B|C=20141230B94A44C28D6B. Fig. 5 shows that B|C analysis flow chart of the present invention, specifically comprises the following steps:

① The first 8 bits and the last 12 bits of the B|C part are respectively encoded. The coding rule for the first 8 digits is the same as that of product production time B, and the coding rule for the last 12 digits is to convert hexadecimal numbers into binary codes:

A=code(B)=code(20141230)=01110 1100 11110;

W=code(C)=code(B94A44C28D6B)=1011 1001 0100 1010 0100 0100 11000010 1000 1101 0110 1011

② Divide W into 2 segments, with the first 17 digits as one segment and the last 31 digits as another segment:

V=10111001010010100

Y=1000100110000101000110101101011

③Take A and V to form a 31-bit binary number X:

X＝0111011001111010111001010010100

④ Exclusive OR operation of X and Y:

Z=X^Y=111111111111111111111111111111

⑤ Decode Z according to the binary code correspondence table to obtain the product model M':

M'＝Decode(Z)＝DZH (Great China Cigarettes)

⑥ Decoding V and B are spliced to obtain T'. The decoding rule of V is: Divide the digits of V into 3 segments according to 5, 6, and 6, and then convert the binary number of each segment into a 2-digit decimal number to obtain a 6-digit decimal number:

b=decode(V)=decode(10111 001010 010100)=231020.

T'=B|b=20141230231020

⑦ Splicing M', T' can get product feature information D':

D'＝M'|T'＝DZH20141230231020

Another embodiment of the present invention is query authentication system scheme two (using form two anti-counterfeiting codes), specifically comprising the following steps:

Step 1 shows and indicates the product model M (DZH), production date (2014.12. 30) for each product in the product production stage, and writes the product feature information D=(DZH20141230231020) of each product into the database;

The generation and printing of the anti-counterfeiting code in step 2 includes the following sub-steps:

(2-1-1) Perform binary coding on the product production time information T: T=20141230231020, code(T)=01110 1100 11110 10111 001010 010100;

(2-1-2) Calculate relation code R: R=1000100110000101000110101101011;

(2-1-3) Connect the result calculated in step (2-1-1) with the relationship code R, and express the result in hexadecimal form, that is, the form 2 anti-counterfeiting code K is 16-digit hexadecimal code:

K=decode(code(T)|R)=decode(01110110011110101110010100101001000100110000101000110101101011)=3B3D729444C28D6B.

(2-2) Anti-counterfeiting code printing:

Form 2 anti-counterfeiting code K is covered with full ink. When it is used for inspection and verification, the ink coating is scratched off and input into the system for authentication.

Step 3: Consumers inquire about authentication and information feedback. The anti-counterfeiting code of the form 2 of Dazhong cigarettes produced at 23:10:20 on December 30, 2014 is: K=3B3D729444C28D6B. Fig. 7 shows the flow chart of query authentication of the second scheme of the present invention, which specifically includes the following sub-steps:

(3-1) The consumer scratches off the coating and sends the anti-counterfeiting code K to the query authentication system, that is, sends 3B3D729444C28D6B to the query authentication system;

(3-2) Inquiry system authentication authentication phase, including the following sub-steps:

(3-2-1) Perform binary encoding operation on the input anti-counterfeiting code K, and the encoding rule is to convert hexadecimal numbers into binary codes:

W=code(3B3D729444C28D6B)=0001110110011110101110010100101001000100110000101000110101101011;

(3-2-2) After removing the high 2 bits of W, it is divided into 2 sections, the remaining first 31 bits are used as one section, and the last 31 bits are used as another section, which can be obtained as follows:

X＝0111011001111010111001010010100

Y=1000100110000101000110101101011

(3-2-3) Perform XOR operation on X and Y to get:

Z=X^Y=111111111111111111111111111111:

(3-2-4) Decode Z and X to obtain the decoded product model M' and product time information T'. Wherein, the decoding of Z is queried according to the product model and the binary code correspondence table, and the product model M'=decode(Z)=DZH (Dazhonghua cigarette) after decoding is obtained.

The decoding of X is divided into two steps: first, the digits of X are divided into 6 segments according to 5, 4, 5, 5, 6, and 6, and the binary number of each segment is converted into a 2-digit decimal number to obtain a 12-digit decimal number. Then calculate the product time information based on the result and the current query time:

temp=decode(X)=decode(01110 1100 11110 10111 001010 010100)

=141230231020.

(3-2) scrape the ink coating of private mark covering off, complete security code k is sent and is inquired about to official's inquiry system, described inquiry system is calculated desired product model m according to the security code k of input ', see whether m ' is equal to product type m, described inquiry system extracts product feature d always according to the security code k of input '=m ' | t ', wherein t ' is calculated desired product temporal information, inquire about described product feature d ' with the presence or absence of in data base, if both answers are all being, then described inquiry system feeds back to consumer query result is true, it is false for otherwise feeding back to this Query Result of consumer, and remind businessman that fake products occurs.

6. method as claimed in claim 5 is it is characterised in that described step (3-2) includes following sub-step:

(3-2-1) to b | c performs the encoding operation, note a=code (b), w=code (c), and w is divided into two sections, is designated as v and y respectively；

(3-2-2) remember x=a | v, xor operation is carried out to x, y and obtains z；

(3-2-3) desired product model m is obtained according to binary code corresponding table decoding z '=decode (z)；

(3-2-4) decoding v obtains production time b=decode (v), and obtains desired product temporal information t with production date b splicing '=b | b；

(3-2-5) splicing m ', t ' can get Product Feature Information d '=m ' | t '.

7. a kind of method for anti-counterfeit being combined based on product feature deformation and being mutually authenticated is it is characterised in that include:

Step 1 is that every product generates Product Feature Information, and described Product Feature Information is added to data base, and described Product Feature Information includes product type m and product temporal information t；

Step 2 is that every product generates a unique security code k and prints according to described Product Feature Information, and described security code k is covered using full ink mode, and wherein, the generation of described security code k includes following sub-step:

(2-1) binary coding is carried out to described product temporal information t, described product temporal information t=b | b, represent and be formed by connecting by production date b and production time b, the date that wherein said production date b record product produces, the Hour Minute Second that described production time b record product produces；

(2-2) calculated relationship code r=fun (m, t)=code (m) ^code (t), wherein, m represents product type, code presentation code operates, and fun (m, t) represents that the coding to m, t carries out step-by-step XOR；

(2-3) result that described step (2-1) encodes is attached with described relation code r, and result is represented in hexadecimal form obtains described security code k；

Described security code k is sent and carries out product inquiry certification and feedback of the information to official's inquiry system by step 3.

8. method as claimed in claim 7 is it is characterised in that in described step (2-2), for inquiry, described product type m is encoded to binary number to the encoding and decoding corresponding relation pre-building described product type m.

9. as claimed in claim 7 or 8 method it is characterised in that described step 3 includes following sub-step:

(3-1) consumer scrapes coating off, and described security code k is sent to inquiry Verification System；

(3-2) the security code k of input is converted into binary code by described inquiry system, is designated as w=code (k)；

(3-3) it is divided into 2 sections of x and y after high for w 2 being removed, and xor operation is carried out to x, y, obtain z=x^y；

(3-4) inquired about according to z table corresponding with binary code, obtain decoded product type m '=decode (z)；

(3-5) x is converted into decimal number according to the coding rule of described product temporal information t, obtains desired product temporal information t '；

(3-6) inquiring about desired product characteristic information d '=m ' | t ' whether there is in described data base, if existing, it is true that described inquiry system feeds back to consumer query result, it is false for otherwise feeding back to this Query Result of consumer, and reminds businessman fake products.
