Description
Technical field
The present invention relates to coding techniques field, particularly a kind of composite coding, especially one kind distinguish by basic coding structure
The method and apparatus of the composite coding becoming.
Background technology
Because one-dimension code, Quick Response Code possess the advantages such as coding information capacity is big, decoding reliability is high, easily make, therefore, by
Gradually introduce in field of anti-counterfeit technology, learn the true of this article by carrying out distinguishing to the one-dimension code of different patterns or Quick Response Code
Pseudo-.
However, because one-dimension code is larger with the code shape of Quick Response Code, being replicated easily or duplicate, to duplication or duplicating
When one-dimension code afterwards and Quick Response Code are distinguished, still can learn the true and false of this article, therefore, one-dimension code is stored with Quick Response Code
Information dangerous.Further, since one-dimension code is relatively simple with the coding rule of Quick Response Code, therefore, also easily it is cracked.One
The one-dimension code that denier is printed on product is cracked by other people with the coding rule of Quick Response Code, just cannot realize its effective work
With it is difficult to strong strike is carried out to fake and inferior commodities.
Therefore, it is badly in need of that a composite coding that can solve the problem that the problems referred to above occurs.
Content of the invention
For weak point present in the problems referred to above, the invention provides the composite coding comprising in a kind of composite coding
The basic coding storage information comprising in storage information and basic coding has matching relationship, and coding cannot be carried out after being replicated
Identification, makes a kind of anti-counterfeiting performance preferably discriminating conduct of the composite coding being made up of basic coding and device.
For achieving the above object, the present invention provide a kind of composite coding being made up of basic coding, described composite coding by
Multigroup basic coding being distributed in order is constituted, and the composite coding storage information comprising in described composite coding is compiled with described basis
Match between the basic coding storage information comprising in code；Described basic coding is one of described composite coding Rectangular Element
Element, described basic coding is not less than the dot pattern of 3*3 square millimeter for effective area.
A kind of above-mentioned composite coding being made up of basic coding, wherein, described dot pattern is a diameter of by least one set
30～40 microns of information point presses aligned transfer composition, is preset with corresponding spacer between two adjacent described information points
From described dot pattern has the shape specified.
A kind of above-mentioned composite coding being made up of basic coding, wherein, described information point include direction reference point, in
Heart reference point and check code.
A kind of above-mentioned composite coding being made up of basic coding, wherein, described composite coding is one-dimension code or Quick Response Code.
The present invention provides a kind of discriminating conduct of the composite coding being made up of basic coding, comprises the following steps:
Obtain the composite coding being printed on product surface by infrared read module；
Composite coding image is distinguished, to obtain composite coding storage information corresponding thereto；
Basic coding image is distinguished, to obtain basic coding storage information corresponding thereto；
Judge whether match between composite coding storage information and basic coding storage information, and phase is fed back according to result
The information answered.
Above-mentioned method, wherein, said method specifically includes following steps:
S10, the composite coding being printed on product surface is obtained by infrared read module；
S20, acquired composite coding image is parsed, can be identified by composite coding data base with being formed
Composite coding data；
S30, in composite coding data base, the composite coding data after parsing is inquired about and mated, if result is
It is then to obtain composite coding storage information corresponding thereto, and execution step s40, if the result is negative, then execution step s50,
Feedback identifying result is invalid, judges article as vacation；
S40, by acquired composite coding image, distinguish constitute composite coding image all basic coding figures
Picture；
S60, basic coding image is parsed, to form the basis volume being identified by basic coding data base
Code data；
S70, in basic coding data base, the basic coding data after parsing is inquired about and mated, if result is
It is then to obtain basic coding storage information corresponding thereto, and execution step s80, if the result is negative, then execution step s90,
Feedback identifying result is invalid, judges article as vacation；
S80, composite coding storage information and basic coding storage information are carried out logic mate, to judge to be therebetween
No have logical relation, if result is coupling, shows that composite coding is true, recognition result is effective, judges article as true, if
Result is to mismatch, then show that composite coding is false, feedback identifying result is invalid, judges article as vacation.
Above-mentioned method, wherein, in step s10, if infrared read module cannot complete at the appointed time to compound
The reading of coding, then show that this composite coding is false or this composite coding damages.
Above-mentioned method, wherein, is a numerical value a in the composite coding storage information of composite coding database purchase；In base
In plinth coded data storehouse, the basic coding storage information of storage is a numerical value b.
Above-mentioned method, wherein, judges the numerical value a corresponding with composite coding storage information and stores letter with basic coding
Whether manner of breathing corresponding numerical value b is the numerical value of formed objects, if result is identical, shows that composite coding is true, recognition result
For effective, judge that article as true, if result is to differ, show that composite coding is false, recognition result is invalid, judge article as
False.
The present invention also provides a kind of device implementing said method, comprising:
