Description
Technical field
The utility model belongs to the anti-counterfeiting mark field, is specifically related to a kind of two-dimensional bar code anti-counterfeiting mark.
Background technology
Anti-counterfeiting mark can help the consumer to differentiate the true and false of commodity rapidly in industry-by-industry, protects the legitimate rights and interests of consumers, and helps the enterprise customer to hit fake products, stop to prevent in batches making, protecting brand names, safeguard corporate image simultaneously, avoids economic loss etc.
The anti-counterfeiting performance of modern product is considered as one of base attribute of product, give one of every product unique, irregular governed coding and be identified in product or its packing on, this coding is generally the one dimension anti-counterfeit bar code.The consumer according to voice suggestion, imports anti-fake code by dialing the unified freephone in the whole nation, and voice system is clearly informed this authenticity of products.Database is not stored security code, and only the anti-fake code to consumer's input carries out multiple encoding rule decryption verification, verifies the result with voice suggestion.The inquiry mode that is provided at present comprises landline telephone inquiry, mobile portable phone inquiry, mobile phone short message enquiry and internet checking etc.
Bar code has obtained people's common concern since occurring, speed of development is very rapid.Its use has greatly improved the speed of data acquisition and information processing, has improved work efficiency, and is that very big contribution has been made in the scientific and modernization of managing.
Because be subjected to the restriction of information capacity, bar code only is the sign to " article ", rather than to the description of " article ".So the use of bar code, the existence of the dependency database of having to.In the place that is not having database and inconvenience networking, the use of bar code has been subjected to bigger restriction, sometimes even become meaningless.In addition, represent the occasion of Chinese character, seem very inconvenient, and efficient be very low with bar code.The development of modern high technology, an urgent demand is represented more information with bar code in limited geometric space, thereby satisfies the needs of Protean information representation.Two-dimensional bar code produces in order to solve the insurmountable problem of bar code just.Because it has characteristics such as high density, high reliability, so can represent data file (comprising the Chinese character file), image, sound etc. with it.Two-dimensional bar code is that high capacity, high reliability information realize storage, carry the also optimal method of automatically identifying and reading.
Bar code is introduced: bar code is not then expressed any information just in a direction (generally being horizontal direction) expressing information in vertical direction, and its certain height is normally for the ease of the aligning of reader.The application of bar code can improve the speed of information typing, the rate that reduces errors, and directly displaying contents is English, digital, simple symbol; The storage data are few, mainly rely on the linked database in the computing machine; Security performance is not high; It is readable poor to decrease dirty back.
The utility model content
The purpose of this utility model is to solve the prior art anti-counterfeiting mark because the defective of the readable difference in not high, the stained back of the confidentiality that adopts bar code to bring provides a kind of use two-dimensional bar code, good confidentiality, stained good readable good two-dimensional bar code anti-counterfeiting mark.
The utility model is achieved through the following technical solutions:
Be a kind of two-dimensional bar code anti-counterfeiting mark, comprise the surface information layer on carrier layer and the carrier layer, it is characterized in that described surface information layer top also is provided with two-dimensional bar code layer, protective clear layer successively.
Protective clear layer is provided with the overlay film layer, described overlay film layer segment or all the two-dimensional bar code layer is hidden.
Also be provided with the bar code layer on the surface information layer of overlay film layer below.Utilize bar code and two-dimensional bar code comprehensively to use, improved the anti-counterfeiting performance of sign.
Described protective clear layer is PET film or PVC film or gloss oil layer.
Surface information layer of the present utility model can be the anti-counterfeiting information figure layer of printing figure layer or radium-shine figure layer or other prior aries.
At present food security is subjected to the helpless of consumers in general's worry and producer always, country has established a lot of food security bar row, it is false proof that comprehensive food has also been done by producer, but food-safety problem is not subjected to the thorough tracking of well prevention and incident always, allow producer spend all thought, also allow the consumer worry.And the present inquiry mode that provides only comprises landline telephone inquiry, mobile portable phone inquiry, mobile phone short message enquiry and internet checking etc.But all be subjected to the restriction of conditions such as time, space, can not, conveniently inquire about product information whenever and wherever possible, and the information storage of one dimension anti-counterfeit bar code is again little, can not more fully reflect product information, inquire about product to the client and brought certain inconvenience, product detail information can better not passed to the client also for product manufacturer and brought worry.
The characteristics of two-dimensional bar code:
1) high density coding, information capacity is big: than the high approximately hundred times of common bar code information capacity.Two-dimensional bar code improves the information density of bar code by the size of utilizing vertical direction.Generally its density is that tens of bar code arrives hundred times, we just can all be stored in product information in the two-dimensional bar code like this, check product information, as long as with the recognizing apparatus scanning two-dimension bar code, therefore do not need to set up in advance database, really realized with the description of bar code to " article ".
2) fault-tolerant ability is strong, has error correction: this makes two-dimensional bar code because of perforation, stained etc. when causing local damage, can correctly obtain recognition in the same old way, but damaged area reaches 50% recovering information still.The used error correction algorithm of the error correction algorithm of two-dimensional bar code and artificial satellite and VCD etc. is identical.This mechanism for correcting errors makes two-dimensional bar code become a kind of safe and reliable information stores and the method for identification, and this is that bar code can't be compared.
3) coding range is wide: this bar code can digitized information be encoded picture, sound, literal, signature, fingerprint etc., shows with bar code; Can represent the multilingual literal; But presentation video data.Most two-dimensional bar codes all have the byte representation pattern, and a kind of mechanism of representing byte stream promptly is provided.We know, no matter which kind of spoken and written languages, all with the performance of the form of internal code, and internal code all was a bytecode when they were stored in computing machine.We just can manage various spoken and written languages information translation are become byte stream like this, and then byte stream is represented with two-dimensional bar code, thereby represent to provide a unprecedented approach for the bar code of multilingual literal.
4) but the presentation video data: since two-dimensional bar code can be represented byte data, and image is many with the storage of byte form, and it is possible that the bar table of image (as photo, fingerprint etc.) is shown as.
5) can introduce encryption mechanism: the introducing of encryption mechanism is the another advantage of two-dimensional bar code.When representing photo such as us with two-dimensional bar code, we can encrypt image information with certain cryptographic algorithm earlier, and then represent with two-dimensional bar code.In identification during two-dimensional bar code, in addition certain again decipherment algorithm just can recover represented photo.So just, can prevent the forgery of various certificates, card etc.
6) reliability of decode height: it is more much lower than common bar code decoding error rate 2/1000000ths, and the bit error rate is no more than 1/10000000th.
7) can introduce encryption measures: confidentiality, antifalsification are good.
8) cost is low, easily makes durable.
9) bar code symbol shape, size variable-scale.
10) can xerox and fax.
The utlity model has the advantage that antifalse effect is good, information content is big.The utility model is applied to two-dimensional bar code in the sign, anti-counterfeiting information figure layer in conjunction with prior art overlay film, bar code, printing figure layer or radium-shine figure layer or other prior aries, strengthened the antifalse effect of sign, the while also represents the information of more products to the client.The utility model has not only been safeguarded the rights and interests of consumption, has solved personation, worry that presenting information is few also for product producer.
