Method for anti-counterfeit relatively common at present has following several: the first is laser anti-false sign, with laser recessiveness ink fluorescent
The symbol of product or special identification icon are printed to the anti-fake label of product by ink-printing techniques, and same class product uses
Same labeling, because anti-fake label is easier to forge, and the anti-fake label forged is used on fake products, causes product
It is true and false to obscure, it is accordingly difficult to effectively anti-fake.Second is cipher counterfeit-proof labeling, and used method is that every product compiles one group
The coding of number, every product is different from, this number is printed on labeling and is covered, while can by this number deposit
For when consumer buys product, the number in mark is passed through phone or the meter that networks in the Computer Database of consumer query
Digital entering computer database in mark is compared identification by calculation machine, and identical is true, difference as vacation, method letter
Single, identification is easy, and is not easy to forge, but in actual use, prints labeling after generating because coded data is that computer is unified.It represents
The true and false coded data of product may be illegally duplicated fraud, meanwhile, the coding that coding also can be recycled on the product that do not inquire makes mark
And be attached on false pain product, antifalse effect it is difficult to ensure that.The third is texture anti-fake, anti-fake with the textural characteristics on its labeling, though
Right more difficult forgery, but the serial number due to being only marked with patch, and be plain code, every piece of mark can be inquired repeatedly, and fake producer can pass through warehouse
Phenomenon is copied the presence or absence of in the necessary textural characteristics i.e. grid reflected when administrator or shop-assistant are by serial number and inquiry on labeling
It is forged after attacking by this feature batch.
In conclusion existing method for anti-counterfeit all has some disadvantages, thus cannot be from preventing fake products at all.
