Description

Method and device for producing anti-counterfeit printing

technical field

The invention relates to a method and a device for generating a print, in particular to a method for generating an anti-counterfeit print and a device for generating an anti-counterfeit print.

Background technique

In order to prevent products from being counterfeited or manage dangerous goods, management labels are traditionally affixed on these items, and serial numbers are printed on the management labels for management purposes. And in order to manage more strictly, these printed serial numbers need to have anti-counterfeiting function. For example, the label on a camera or a digital video camera needs a label with anti-counterfeiting function to determine whether the product is a company product or a pirated product.

Traditionally, when producing printed matter with an anti-counterfeiting mechanism, the required serial number is generally generated in the form of a plain text file. After the required serial number is generated, it is provided to the outsourced digital printing manufacturer for printing. Traditionally, the serial number and anti-counterfeit characters need to be printed twice, so it takes a lot of time and manpower and is prone to displacement. In this process, once the customer's information or anti-counterfeiting mechanism leaks out, the loss of the manufacturer and the customer of the label will be very serious. And for different customers or different products, it is also necessary to adopt different anti-counterfeiting mechanisms.

In addition, most of the traditional printing anti-counterfeiting characters are produced by simple methods. Once the time is prolonged, there will be a problem that there are not enough choices for the generation of anti-counterfeiting characters. In addition to the aforementioned problems, the traditional simple anti-counterfeiting character generation method will have a very high chance of being cracked by interested personnel after a long time. Once the anti-counterfeiting mechanism is cracked, all losses of customers will be difficult to estimate. Therefore, there is a problem that the traditional printing anti-counterfeiting mechanism is too simple, and it is easy to be cracked by interested personnel.

When the first parameter is divisible by any judging prime number, it is determined that the first parameter meets the judging condition corresponding to judging the prime number. And when the first parameter is not divisible by any judging prime number, it is determined that the first parameter meets the otherwise condition. Among the above-mentioned judging prime numbers, at least one judging prime number is 2, 3, 5 or 7.

According to an embodiment, the position of the check code is the sum of the first parameter, the second parameter, the third parameter, and the check prime numbers corresponding to the first parameter, and then divide by the length of the sequence number string, and then divide by the sequence number Add 1 to the remainder of the length of the string. The serial number character string above represents a serial number value, and the first parameter, the second parameter, and the third parameter may be user-defined values or results calculated according to user-defined formulas. Among the check prime numbers mentioned in the preceding paragraph, at least one check prime number is 11, 13, 17, 19 or 23.

According to an embodiment, the step of "sequentially combining the first substring, the verification code and the second substring to form the anti-counterfeiting print" includes the following steps. Set and apply the printing style of the first substring, check digit and second substring. The printing style of the check code is different from the printing style of the first substring or the second substring. And combining the first sub-string, the check code and the second sub-string of the applied printing style into anti-counterfeiting prints.

According to the printing style of the first substring, the check code and the second substring described in the preceding paragraph, it may include font, font size, font color, bold, italic, underline, space size or background color.

According to an embodiment, the present invention provides a device for generating anti-counterfeit prints, which is used to receive a serial number string, and the serial number string includes a plurality of bit codes.

detailed description

The detailed features and advantages of the present invention are described in detail below in the embodiments, the content of which is sufficient to enable any person familiar with the related art to understand the technical content of the present invention and implement it accordingly, and according to the content disclosed in this specification, the claims and the appended Figure, any person familiar with the related art can easily understand the purpose and advantages of the present invention. The following examples further illustrate the concept of the present invention in detail, but do not limit the scope of the present invention in any way.

The invention provides a method for generating anti-counterfeit prints and a device for executing the method for generating anti-counterfeit prints. Wherein the device for generating anti-counterfeit prints can execute the method for generating anti-counterfeit prints; and the device for generating anti-counterfeit prints can be a personal computer (Personal Computer, PC), a notebook computer (NoteBook), a server (Server), portable type device or any device that can implement the method for generating anti-counterfeit prints proposed by the present invention as described above.

Please refer to FIG. 1 , which is a flowchart of a method for generating anti-counterfeit prints according to an embodiment of the present invention. The device for generating the anti-counterfeit print may include the following steps when implementing the anti-counterfeit print method. Firstly, in step S100, the device for generating anti-counterfeit prints receives a serial number string, which includes a plurality of character codes. The sequence number string can be a number and the length of the sequence number string can be adjusted as needed. For example, a serial number string of a customer is "00000001". Then the above sequence number length is 8 codes and the sequence number value is 1.

In step S110, the generating device of the anti-counterfeiting print executes a verification code generation program to calculate a verification code position according to the serial number character string and a verification code parameter set and use the character code at the verification code position as a verification code code. The aforementioned check code position is the position of the check code in the serial number string. The check code is a character with anti-counterfeiting function in the serial number string, and a different format from other characters can be applied to the check code, for example, italic or bold can be applied. For example, the serial number string of a customer is "000000 2". Then the " " is the check code of this serial number, and it is applied in bold italics.

In step S120, the part of the serial number string that is located before the position of the check code is defined as a first sub-string, and the part located after the position of the check code is defined as a second sub-string. The part before the check code position is all character codes before the check code position, and the part after the check code position is all character codes after the check code position. For example, the serial number string "0000 0006" from the fifth digit from the right" " is the check code of the serial number string. The "0000" before the check code position is the first substring; the "0006" after the check code position is the second substring.

Then in step S130, the first sub-string, the verification code and the second sub-string are sequentially combined to form an anti-counterfeiting print. The anti-counterfeiting print can include a character string printed on the label. This character string has a special anti-counterfeiting mechanism, allowing the issuer of the label, the manufacturer of the product with the label and the end user to judge the label. Is it genuine. According to an embodiment, in addition to the character string, the anti-counterfeiting print can also include a bar code (Bar code), a quick response code (Quick Response Code, QR Code) or a totem to facilitate product management or increase product identification Spend.

Please refer to FIG. 2 , which is a schematic diagram of an example of anti-counterfeit printing according to an embodiment of the present invention. Wherein FIG. 2 shows a plurality of anti-counterfeit labels 500 , and each anti-counterfeit label 500 has an anti-counterfeit print 510 . And in the anti-counterfeit print 510, the character codes using both "bold" and "italic" printing styles are the check codes of the present invention. As shown in Figure 2, the position of the check code of the anti-counterfeit label 500 does not have a fixed position or fixed characters in the serial number of a batch, so it can effectively prevent people with intentions from forging the anti-counterfeit label 500 with the anti-counterfeit print 510 .

During the production process of the label, the manufacturer of the label can also add special words in the anti-counterfeit printing 510 to indicate that this batch of labels is only for verification purposes, as shown in FIG. 3 . The label with the word "school bus" in the upper half of FIG. 3 is a school bus label 600 for a school bus. In the lower half of Fig. 3 is the mass production label 610 which is officially mass-produced and has anti-counterfeit printing, and the anti-counterfeiting printing of the mass-production label 610 in the lower half of Fig. The character code of printing style is the verification code of the present invention. In the mass production label 610 in the lower part of FIG. 3 , it can be seen that the check code does not have a certain position and fixed characters, so it has a good anti-counterfeiting effect.

Next, please refer to FIG. 4 , which is a flow chart of a verification code generation program according to an embodiment of the present invention. The verification code generation procedure may include the following steps. In step S200, the device for generating the anti-counterfeit print first obtains a first parameter k, a second parameter i, and a third parameter j of the verification parameter set. Next, in step S210, it is judged whether the first parameter k meets one of a plurality of judgment conditions, wherein each judgment condition corresponds to a check prime number. And in step S220, according to the second parameter i, the third parameter j, the serial number character string and the check prime number corresponding to the judgment condition that the first parameter k meets, the position of the check code is calculated, and the character code on the check code position is as a checksum. And at least one check prime number can be 11, 13, 17, 19 or 23.

According to an embodiment, the position of the check code is the sum of the sum of the first parameter k, the second parameter i, the third parameter j, and the check prime numbers corresponding to the first parameter k, divided by the length of the serial number string, and then Add 1 to the remainder of division by the length of the sequence number string. Wherein the first parameter k, the second parameter i and the third parameter j may be user-defined values or results calculated according to a user-defined formula. These parameters can be a preset value, or the device for generating the anti-counterfeit print can customize the values of the aforementioned three parameters. Among the self-defined values of the anti-counterfeit print generation device, the anti-counterfeit print generation device can use a self-defined formula to calculate or directly specify three parameter values. For example, the sum of the first parameter k, the second parameter i and the third parameter j may be calculated as a new first parameter k, and then it is judged whether the new first parameter k meets the judgment condition.

It should be noted that when implementing the verification code generation program, the number of parameters can be increased according to customer requirements or other actual conditions, and the custom formula used to calculate parameters can also be dynamically modified, and even the number of check primes and judgment conditions can be increased. Or judge the number and value of prime numbers. With a high degree of flexibility and a definable space to increase security, the probability of being cracked by a malicious person can be reduced to a considerable extent. The calculation method and calculation example of the position of the check code will be described in detail below.

One of the judging conditions of the check code generation program according to an embodiment of the present invention is an else condition, and each judging condition other than the otherwise condition corresponds to a judging prime number. Please also refer to FIG. 5 , which is a flow chart of judging whether the first parameter k meets one of the judging conditions according to an embodiment of the present invention. The device for generating the anti-counterfeit print can use the following steps to judge whether the first parameter k meets one of the judgment conditions. In step S300, it is determined whether the first parameter k is divisible by any determined prime number. When the first parameter k is divisible by any judging prime number, it is determined that the first parameter k meets the judging condition corresponding to judging the prime number, as shown in step S310. On the contrary, when the first parameter k is not divisible by any of the judging prime numbers, it is judged that the first parameter k meets the otherwise condition, as shown in step S320. And at least one judging prime number can be 2, 3, 5 or 7.

The serial number character string mentioned above can be expressed as a serial number value, for example, it can be "00000001". The aforementioned first parameter k may be the sum of the first default value plus the serial number value. The second parameter i may be the sum of a second default value plus a third default value. The third parameter j may be a fourth default value.

Wherein the first default value, the second default value and the third default value may be a group of numbers specified by the customer or may be randomly generated numbers. For example, if the serial number is "000001" and the first default value specified by the customer is 900, then the first parameter k is 900+000001=901. For another example, if the customer specifies that the second default value and the third default value are 700 and 800 respectively, then the second parameter i is 700+800=1500. The fourth default value may be an American Standard Code for Information Interchange Code (ASCIICode) of numbers or uppercase English letters. For example, when the fourth default value is A, its ASI code is 66. When the fourth default value is Z, its ASI code is 90.

Please refer to FIG. 6 , which is a flowchart of step S130 according to an embodiment of the present invention. In step S400, the device for generating anti-counterfeit prints can respectively set and apply the printing style of the first substring, the verification code and the second substring, wherein the printing style of the verification code is the same as that of the first substring or The printing style of the second substring is different. In step S410, the first sub-string, the verification code and the second sub-string that have applied the printing style are synthesized into anti-counterfeiting prints.

Wherein the print style of the first substring, the check code and the second substring described in the previous paragraph may include font, font size, font color, bold, italic, underline, space character size, background color of the character Or other recognizable font styles can be used as printing styles.

The method and device for generating the anti-counterfeit print can be set with a plurality of different judgment conditions, and a corresponding formula can be selected according to the satisfied conditions to calculate the position of the fixed check code. For example, when the first parameter k can be divisible by the prime number 2, the following formula can be selected as the position of the check code:

iCheckCode=(((i+j+k)+13)%iDigits)+1 (Formula 1).

Wherein in Formula 1, iCheckCode is the position of the check code. k is the first parameter. i is the second parameter. j is the third parameter. The 13 added after the first parameter plus the second parameter plus the third parameter is a check prime number. iDigits is the serial number length.

In addition, when the first parameter k can be divisible by the prime number 3, the following formula can be selected as the position of the check code:

iCheckCode=(((i+j+k)+17)%iDigits)+1 (Formula 2).

When the first parameter k can be divisible by the prime number 5, the following formula can be selected as the position of the check code:

iCheckCode=(((i+j+k)+19)%iDigits)+1 (Formula 3).

When the first parameter k can be divisible by the prime number 7, the following formula can be selected as the position of the check code:

iCheckCode=(((i+j+k)+23)%iDigits)+1 (Formula 4).

And when the first parameter k cannot be divisible by any prime number, the following formula can be selected as the position of the check code:

iCheckCode=(((i+j+k)+11)%iDigits)+1 (Formula 5).

In Formula 2, Formula 3, Formula 4 and Formula 5, the definitions of iCheckCode, k, i, j, and iDigits are the same as those in Formula 1 and will not be repeated here. 11, 17, 19 and 23 in Formula 2, Formula 3, Formula 4 and Formula 5 are check prime numbers in different embodiments.

And in addition to the above formula, the customer can also specify a set of numbers, where the set number can be 1, 2 or 3, for example. The method and device for generating anti-counterfeit prints can automatically calculate the first parameter in different ways according to the number of groups selected, so as to increase the anti-counterfeit effect. For example, when the customer selects group number 1, the second parameter i is the second default value. When the customer selects the group number 2, the second parameter i is the second default value plus the third default value, wherein the third default value may be 1911, for example. When the customer selects the group number 3, the second parameter i is the second default value plus a different third default value, and the third default value at this time may be 2012, for example. The aforementioned second default value may be a value specified by the customer, or other default values.

According to the above formulas 1 to 5, if the total number of character codes is i, the position of the check code may be between the second character and the i-th character. And the first substring contains at least one character code, and the second substring contains at least zero character codes. In addition, other formulas may also be used in different embodiments, and check code positions may be selected in different ways. For example, multiple continuous check codes may be selected, or multiple scattered check codes may be selected.

For example, assume that the customer specifies that the second default value is 101, the number of groups is 1, the fourth default value is Z, the first default value is 0, and the serial number length is 9. Because the number of groups is 1, the second parameter i is the second default value 101, and the first parameter k is the first default value 0 plus the serial number value (the serial number value is 1. Since the length of the serial number specified by the customer is 9, the serial number value is "000000001"), so the first parameter k is equal to "000000001". The third parameter j is the ASCII code (ASCII Code) of Z, so the third parameter j is 90. Wherein, since the first parameter k is equal to 1 and cannot be divisible by any judging prime number, the generating device of the anti-counterfeiting print will use formula 5 to calculate the position of the check code, and the calculation result is as follows:

iCheckCode＝(((101+90+1)+11)%9)+1＝6

From the above results, we can know that the check code position of this serial number is the sixth digit from the right side of the character string. If the check code is a bold italic element. Then the complete anti-counterfeiting printed serial number is "101-Z-000 00001".

For another example, assume that the customer specifies that the second default value is 1, the group number is 1, the fourth default value is 3, the first default value is 915, the sequence number length is 8 and the sequence number is 2. Because the number of groups is 1, the second parameter i is the second default value 1. The first parameter k is the first default value 915 plus the serial number value (the serial number value is 2, since the length of the serial number specified by the customer is 8, the serial number value is "00000002"), so the first parameter k is 915 plus 2 equals 917. The third parameter j is the fourth default value, so the third parameter j is equal to 3. Wherein the first parameter k is equal to 917 and can be divisible by 7 in the judging prime number, so the generating device of the anti-counterfeiting print will use formula 4 to calculate the position of the check code, and the calculation result is as follows:

iCheckCode＝(((1+3+917)+23)%8)+1＝1

From the above results, we can know that the check code position of this serial number is the first digit counted from the right side of the string, if the check code is a bold italic element. Then the complete anti-counterfeit printing serial number is "A00000002".

Also assume that the customer specifies that the second default value is 1, the number of groups is 2, the fourth default value is 3, the first default value is 915, the sequence number length is 8 and the sequence number starts from 1. Since the number of groups is 2, the second parameter i is 1912 equal to the second default value 1 plus the third default value 1911. The first parameter k is the first default value 915 plus the serial number value (the serial number value is 1. Since the length of the serial number specified by the customer is 8, the serial number value is "00000001"), so the first parameter k is 915 plus 1 equals 916. The third parameter j is the fourth default value, so the third parameter j is equal to 3. Wherein the first parameter k is equal to 916 and can be divisible by 2 in the judging prime number, so the generating device of the anti-counterfeiting print will use formula 1 to calculate the position of the check code, and the calculation result is as follows:

iCheckCode＝(((1912+3+916)+13)%8)+1＝5

From the above results, we can know that the check code position of this serial number is the fifth digit from the right side of the string, if the check code is a bold italic element. Then the complete anti-counterfeiting printed serial number is "A000 0001".

Based on the above, printing manufacturers can generate anti-counterfeit prints for various product labels through the method and device for generating anti-counterfeit prints proposed by the present invention, and can provide customers with better anti-counterfeit mechanisms. The anti-counterfeiting mechanism provided above is more random and unpredictable than the traditional method, and there is no problem that a certain number has a higher probability when using the random number seed built in the program traditionally. Therefore, the generation method of the anti-counterfeit print proposed in the present invention will make it even more difficult for interested persons to know the rules, so the probability of the anti-counterfeit print being cracked is lower than that of the traditional method. Also because of the better anti-counterfeiting mechanism, the customer's products can be better protected, and the loss caused by the cracked anti-counterfeiting mechanism is greatly reduced.

On the other hand, the method for generating anti-counterfeit prints and the device for generating anti-counterfeit prints proposed by the present invention can also greatly reduce the time for generating anti-counterfeit prints. Due to the use of modern computer calculations, the method for generating anti-counterfeit prints proposed by the present invention will not increase the time due to the complexity of the traditional method. On the contrary, due to the extensive use of computer calculations, prints with different anti-counterfeiting mechanisms can be produced quickly and in large quantities. Also because of the aforementioned reasons, printing manufacturers with better anti-counterfeiting printing methods can naturally have higher efficiency and higher competitiveness.
