Difference, this error have the characteristics that can be changed at random, and the feature extraction that can be used as the bar code comes out, and the identification for becoming bar code is special
Sign is identification code；When acquiring identification code, the absolute value of bar code strip unit and dummy cell width is acquired；It is acquired simultaneously in label
Standard scale pulse signal is generated inside device, by institute in the corresponding width range of each unit and dummy cell of bar code
The standard scale pulse signal for including is counted, and is included in each unit of calculating or the corresponding width range of dummy cell
The count value of standard scale pulse signal by each count value or is bar width quantized value, and each bar code that is combined
Width granularity value forms identification code, either further will be on the basis of the bar width quantized value of the first unit or dummy cell
Value, calculates separately ratio value of the bar width quantized value of remaining each unit or dummy cell relative to a reference value, will
Relatively wide angle value of the ratio value being calculated as corresponding with the ratio value unit or dummy cell, and will be each relatively wide
The relative value that angle value is arranged successively or is combined forms identification code, this identification code is special by the scale for retaining bar code
Sign.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
Basic principle of the invention: Antiforge bar code label of the present invention belongs to modified innovation；Make full use of routine
Bar coded sticker noiseproof feature or the item and empty width difference of low resolution printing, using bar code width digital quantization side
Method and and based on the thought design label information collector, corresponding identification code is acquired out from Conventional bar codes label,
To form the characteristic information with uniqueness of bar coded sticker, Conventional bar codes label is assigned with antiforge function；With natural row
The interference copied except conventional resolution；Or be aided with label high-resolution and copy sensitive prompt, reach visual inspection high-resolution
The imitated effect of rate；Thus achievement one it is completely new, it is with unique identifier, can be applied alone, Antiforge bar code mark that can be nested
Label.
It should be noted simultaneously that: Conventional bar codes labels is source only so identification code with uniqueness can be acquired
It is determined in the simple code and its noiseproof feature of bar code；Bar coded sticker is commonly used in mark product or logistics ring
In the outer packing in border, label surface is allowed to have certain deformation, and by collector it is interior function filter out these deformations and produced
Raw influence, these deformations are embodied in bar coded sticker standard, and the deformation rate allowed is up to 30%；Institute within this range
The random deformation of generation, it is sufficient to form the uniqueness characteristic of bar coded sticker.
Based on the above principles, Antiforge bar code label of the present invention can be Conventional bar codes label, by successively
Bar width digital quantization acquisition method each bar width quantized value obtained is carried out to each unit on label and dummy cell,
And each bar width quantized value that will be combined is label anti-counterfeit identification code, or for first item or empty bar width
Be worth on the basis of quantized value, calculate remaining each and empty relative width dimensions, i.e., each with hollow bar code width granularity value phase
It is for the ratio of first item or hollow bar code width granularity value, and by the relative value for each bar width quantization that is combined
Label anti-counterfeit identification code.Simultaneously in view of the print request of existing bar coded sticker, each relative value must be between 9.9 and 0.1
Between, i.e., beyond datum strip or sky multiple, less than datum strip or sky multiple without departing from 10 times except, therefore, setting
Determine to can use two effective digitals of the relative value decimal point or so when the value of relative value.By label anti-counterfeit identification code and bar shaped
Code label coding binding completes Conventional bar codes label to Antiforge bar code mark using the fake certification code as bar coded sticker
Label transformation.Such as Fig. 1, wherein for security barcode label it is biggish it is a be Fig. 1 a, in figure instruction 1 taken away for bar code reading open and
The dead zone of end；Instruction 2 is first symbol；Instruction 3 is end mark；Instruction 4 encodes for Conventional barcode；For security barcode label
It is lesser a for Fig. 1 b.
In addition, above-mentioned Antiforge bar code label, also has the versatility with existing bar coded sticker, reason is as follows: existing
Bar coded sticker is divided into three classes by usage mode, and one kind is used for commodity code (ENA-13, ENA-8, UPC-A, UPC-E): utilizing
Sky/item of bar code and width/narrow coding of bar code only limit digital coding, label fixed length but adjustable (the enlargement ratio 0.8- of permission
2.0), bar code elements normal width 0.33mm, allowable error 0.101mm (its error range close to 30%)；This kind of bar shapeds
Code is used by unification of the motherland is specified, is encoded as type of merchandize, generally should not be using nested tagged manner；One kind is in enterprise
Portion's product or part management coding (Code 128, Code 93): sky/item of bar code and width/narrow volume of bar code are utilized
Code can be number, letter and symbolic coding；Its information content is larger, and tag length is variable, bar code high density, and coding is complicated,
It is suitble to directly application or nested mode application Antiforge bar code label.One kind encodes (ITF 25, ITF for logistics management
14): using width/narrow coding of bar code, only limiting digital coding, tag length is fixed length or variable-length, but is usually used in marking
Know the number of regular length；It encodes simple, and recognition efficiently, when the suitable length of locking especially, has stronger recognition
And anti-interference ability, it is mainly used for transportation and packing, especially printing condition is poor, does not allow to print EAN-13 and UPC-A bar shaped
It is applied when code；It is similarly suitable directly to apply Antiforge bar code label or nested mode application Antiforge bar code label.
Preferably, to guarantee the reliable of label anti-counterfeit identification code acquisition and stablizing, the size of the Antiforge bar code label
Specification is more than or equal to standard scale bar coded sticker；The standard scale label is under default label information amount, and label is adopted
The acceptable minimum dimension of storage resolution ratio；The Antiforge bar code label of standard scale specification is set, is acquired with canonical tag
The viewfinder range of device.
Preferably, if the Antiforge bar code label sizes are standard scale bar coded sticker size, directly acquisition is mentioned
Take each bar width quantized value or relative value to obtain label anti-counterfeit identification code.
Preferably, if the Antiforge bar code label sizes are greater than the bar code mark of standard scale bar coded sticker size
Label, then the Antiforge bar code label is nested Antiforge bar code label；
The nested Antiforge bar code label, includes at least:
Positioned at this label of bottom, which is the bar code mark that size is greater than standard scale bar coded sticker size
Label；
And along the partial region in bar code information area that the bar code scan direction of described label is nested in this label
Lock label；The lock label extends partially into the bar code information area of this label for the dead zone of standard scale label and its both ends, to cut
The part bar code information for taking this label constitutes the bar code reading area of this nested Antiforge bar code label；Bar code reading area
Setting allow users to by bar width digital quantization acquisition method acquire bar code reading area bar code information, in turn
Obtain the anti-counterfeiting identification code of the nested Antiforge bar code label.
Further, the lock label is when intercepting the part bar code information of this label, so that described label is described
The bar code information for locking label interception retains the bar code information area that can be distinguished by label collector.
The identification code of above-mentioned nested Antiforge bar code label, can be obtained by plain mode, i.e., directly described in acquisition
Bar code reading area obtains identification code；The identification code that label itself can be locked with secondary acquisition, will be described in the identification code and acquisition
Bar code reading area obtains identification code and is combined into mixing identification code, and this more complex identification code can increase its complicated journey
Degree promotes anti-fake reliability, adapts to the higher occasion of security requirement；Therefore nested Antiforge bar code label can prevent letter
Single duplicate is copied.
The nested Bar Codes Identification Label specimen signature as shown in Fig. 2 a, Fig. 2 b and Fig. 2 c it is found that specimen signature I, specimen signature II with
And the coded data of specimen signature III is identical, the dead zone for intuitively locking label both ends extends partially into the bar code of this label
The position of the information area is also consistent, but right to the random width error institute obtained after being handled by bar code width data quantization
The identification code answered be then it is entirely different, be specifically detailed in shown in Fig. 2 d it is corresponding with specimen signature I, specimen signature II and specimen signature III with
Machine width degree error difference point schematic diagram；Each Pictorial examples are to use identical one group of larger label and one group of smaller label,
Smaller label is nested in larger label same position, identical conventional encoded information can be acquired out in nested region,
The Antiforge bar code label is also suitably applied in existing " one yard of an object " label technique simultaneously, gives every product one only
One identification tag.
Switch to Antiforge bar code label from a Conventional bar codes label, needs the identification code acquisition function of barcode scanner
Energy and identification code collected；Also need to increase identification code other than having the setting of every unit of conventional tags collector
Extraction unit, to make it have identification code acquisition function；Identification code extraction unit is based on bar width digital quantization principle and sets
Meter acquires bar code information according to standard scale label (while collector need to fix viewfinder range), with standard scale step-by-step counting,
The width value of each bar code is measured, to capture the corresponding width characteristics information of each bar code；The identification code is bar code
Value of the counting of each unit standard scale pulse corresponding with dummy cell by quantization in tag recognition code reading area, or
Person calculates the relative width dimensions of remaining each with sky on the basis of first stripe quantization value or empty quantized value, i.e., and each
Ratio with empty quantized value relative to first item or sky quantized value, and the opposite of each bar width quantization that will be combined
The sequence of value；By the identification code that the above method acquires, the item and empty figure for having recorded bar code make a variation, and this variation is not only
Be embodied in different barcode encodings, even while identical barcode encoding also have different identification codes；That is this hair
The bright identification feature that item and empty figure variation are transformed into Antiforge bar code label by bar width digital quantization method.
Specifically, such as Fig. 3, the Antiforge bar code label collector, including five units: scanning element, interface unit,
Identification code extraction unit, coding extraction unit, control unit；
The scanning element, for Antiforge bar code label emission detection light and receiving corresponding feedback signal；
The interface unit connection scanning element, identification code extraction unit, coding extraction unit and control unit；
The identification code extraction unit connects scanning element by interface unit, for obtaining Antiforge bar code label
Identification code, and the identification code obtained by interface unit to server-side transmission；
The coding extraction unit connects scanning element by interface unit, for obtaining the volume of Antiforge bar code label
Code data, and the coded data obtained by interface unit to server-side transmission；
And the control unit as central processing unit, the control unit are pre-stored Antiforge bar code tag recognition journey
