Description
Technical field
The present invention relates to field of anti-counterfeit technology, specifically a kind of compound two dimensional code, watermark, miniature word anti-fake code system
Work and verification method.
Background technique
Common security code generallys use common black and white two dimensional code or common color 2 D code on the market at present, prevents
Pseudo- effect has certain limitations, and is unable to satisfy higher and higher anti-fake requirement.
It is directed to miniature word simultaneously, it is common practice to directly printed according to preset text shape and regular font,
The text printed in this way is that good effect is not achieved according to different printer precision, relatively fuzzy sometimes or only
It can be bigger text.
The anti-fake setting of market be the anti-counterfeiting identifications main points such as miniature word, watermark are each attached to a fixed position,
And the position is to be provided separately with two dimensional code, reduces anti-fake concealment and security impact, and be provided separately presence
Cannot problem effectively be wasted using effective area and stamp with the size.Simultaneously as after ordinary QR code is replicated and forges, no
It can be by effectively debating the deficiency of the true and false with other tools.
