Description
Technical field
The invention belongs to planar bar code technology fields, and in particular to a kind of construction method for character anti-fake in two dimensional code.
Background technique
Become increasingly prosperous with the continuous development of science and technology with commodity economy, the safety of information and identification at
For the topic of social extensive concern.Anti-counterfeiting mark currently used in the market is two-dimensional bar code, it is by with specific geometry
The chequered with black and white figure that figure is distributed in the plane according to certain rules, to express a large amount of information.Traditional anti-counterfeiting technology
Mainly have: laser anti-counterfeit, fluorescence falsification preventing, magnetic anti-counterfeit, temperature become anti-fake, drip anti-fake etc., using optical property, physical property or
Chemical characteristic identified, or using certain special materials property carry out it is anti-fake, with the development of science and technology also
It is by with the progress anti-counterfeit recognition in conjunction with special instrument.It is the either stealth of these anti-counterfeiting technologies or dominant, some
There are with low content of technology, structure combination is easily decrypted；Although there are also some anti-counterfeiting technology manufacturing technology difficulty it is larger and be difficult to by
It is imitated to imitate, but have manufacture craft or method is complicated, expensive, precision less good job, it is unstable and vulnerable to it is extraneous because
The multiple technologies defects such as element interference, have been unable to meet the needs of today's society information security development.Therefore, with economic hair
Exhibition, in two-dimension code anti-fake field, there is an urgent need to a kind of new safe identification technologies.
Summary of the invention
The purpose of the present invention is to solve the above problems to provide a kind of building side for character anti-fake in two dimensional code
Method, by anti-fake bottom and character layer by the character and number and its odd number or its even number than 0, capitalization in two dimensional code
Letter or lowercase and its putting in order in alphabet count, the letter in text and its stroke number or its Chinese phonetic alphabet exists
The several and phosphor pattern that puts in order in alphabet organically combines, and improves the anti-tamper security coefficient and mark of two dimensional code
Know by global transfer performance.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: it is a kind of for anti-fake character in two dimensional code
Construction method, comprising the following steps:
Step 1: first according to the number of character required on two-dimension code anti-counterfeit character zone, a character, which occupies one, to be prevented
Pseudo- bottom determines the number of anti-fake bottom；A character layer is covered on an anti-fake bottom simultaneously, determines the number of character layer；
Step 2: preparing several character layers, printing or laser one character of stamp, the word on the egative film of a character layer
Symbol is any one of numerical character, upper case alphabetic character, lower case alphabetic character, alphabetic character；The numerical character be by
The numeric type that pattern I is combined into is constituted, and the upper case alphabetic character is a capital letter parent form structure being combined by pattern II
At the lower case alphabetic character is made of the small letter parent form that pattern III is combined into, and the alphabetic character is by scheming
A character type that case IV is combined into is constituted, wherein pattern I, pattern II, pattern III, pattern IV shape be polygon, animal
Figure, plant figure, number, text, one of shape in letter, and the shape of pattern I, pattern II, pattern III, pattern IV
It is different；
Step 3: printing several anti-fake bottoms in two-dimension code anti-counterfeit character zone, the anti-fake bottom and character thereon
Layer is corresponding；Print a phosphor pattern on each anti-fake bottom, and the fluorogram that fluorescence is sent out in different anti-fake bottom printings different
Case；Wherein, the phosphor pattern includes several figures, is covered with fluorescent material on figure, is located to several pattern symmetricals anti-
On pseudo- bottom；The phosphor pattern be can't see under visible light, be that can see under the excitation wavelength that it issues fluorescence
's；
The shape and number of the figure are determined by the character on the corresponding character layer of the anti-fake bottom: if character is number
The shape of character, the figure is identical as the shape of pattern I, and number is equal to the numerical value of the number；If character is capital letter
The shape of alphabetic character, the figure is identical as the shape of pattern II, and number is equal to arrangement of the capitalization in alphabet
Ordinal number；If character is lower case alphabetic character, the shape of the figure is identical as the shape of pattern III, and it is small that number is equal to this
Write female number that puts in order in alphabet；If character is alphabetic character, shape and the IV shape phase of pattern of the figure
Together, number is equal to the stroke number of the text or put in order number of the letter in alphabet in its Chinese phonetic alphabet；
Step 4: the character layer prepared in step 2 is covered in corresponding step 3 and is printed with phosphor pattern
Anti-fake bottom on, make character layer and anti-fake bottom combine anti-fake character in i.e. two dimensional code construction method complete.
Preferably, the animal figure refers to that, by the pattern of animals shaped formation, plant figure refers to by plant shape shape
At pattern.
Preferably, the fluorescent material is inorganic fluorescent material or organic fluorescence materials.
Preferably, different numerical characters is to be combined into corresponding numeric type by different patterns I to constitute.
Preferably, different upper case alphabetic characters is to be combined into corresponding capital letter parent form by different patterns II to constitute.
Preferably, different lower case alphabetic characters is to be combined into corresponding small letter parent form by different patterns III to constitute.
Preferably, different alphabetic characters is to be combined into corresponding character type by different patterns IV to constitute.
The invention has the following advantages: being spelled by the pattern printed on the egative film of character layer or laser is stamped different
At the character in two dimensional code such as number, capitalization, lowercase or text；Pattern used in each intercharacter is also different simultaneously,
It includes that hiding pattern increases the difficulty that the character printing in two dimensional code imitates that this, which allows in the character in visible two dimensional code,；
Phosphor pattern is printed on anti-fake bottom by corresponding at it, phosphor pattern is formed by the figure for being covered with fluorescent material, the shape of figure
It is related that shape and the number pattern different from corresponding character layer on the anti-fake bottom are combined into the character in two dimensional code, according to character
Type such as numerical character, upper case alphabetic character, lower case alphabetic character or alphabetic character, by phosphor pattern and number odd number or
The stroke number or its Chinese of putting in order number, text of its even number, capitalization or lowercase than 0 in alphabet
Put in order number of the letter in alphabet in language phonetic combines well, and the phosphor pattern is seen under visible light
Less than, it can see under the excitation wavelength that it issues fluorescence, effectively improve the anti-fake difficulty of two dimensional code.
