Abstract

The present invention relates to a method for resisting counterfeit by using random structure grain characteristics of material which is difficult to be copied by utilizing existent technique as anti-counterfeit information carrier. It is characterized by that it utilizes the random grain pattern and makes it undergo the processes of computer scanning, identification and encryption treatment to produce another enciphered converted pattern, and said pattern can be directly transferred and printed on the product with original random grain pattern, the enciphered converted pattern carries the complete or partial information of original random grain pattern, and an indenpendent recognizer with correspondent deciphering program is used to compare two patterns to distiguish the true from the false.

Description

A kind of method for anti-counterfeit of random grain

The present invention relates to a kind of method for anti-counterfeit, particularly a kind of random grain that utilizes reaches the independently method for anti-counterfeit of recognizer Direct Recognition authenticity of products.

Chinese patent---the structure grain anti-fake method (application number 98116462.5) of application on August 8th, 1998, at first random grain pattern and the numbering thereof with material is stored in the Computer Database terminal, the user compares inquiry by communication network then, and its defective is:

1. this method needs the pattern and the coding of each product are carried out the scanner uni typing, is stored in then in the computing machine, and workload is big, the cost height, and each inquiry needs the payment communication cost;

2. this method need and be set up huge computer data storage system by means of communication network;

3. there is network security hidden danger in this method;

4. the product that this method is big to quantity and added value is low is very uneconomical;

5. this method needs long-time all product informations of storage, could guarantee the search request that fraction product possibility produces because of the long-term storehouse that stagnates.

The objective of the invention is to: provide a kind of material generation random grain that utilizes to carry out false proof method, do not need to deposit pattern and coding in computer network recognition system, cost saving; Not by network, eliminated information security hidden danger, inquire about the nonpayment communication cost at every turn; This method is applicable to various products.

The present invention is achieved in that a kind of random grain false-proof method, comprising:

1. making anti-counterfeiting mark:

(1) the random grain image in product or last certain zone of packing is scanned;

(2) scanning result is carried out computer Recognition and encryption, generate and encrypt conversion

Pattern;

(3) will encrypt the conversion pattern is printed on product or the packing;

2. anti-counterfeiting mark is discerned:

(1) corresponding decrypted program is set on recognizer;

(2) with recognizer picked-up product or random grain pattern of packing and encryption conversion

Pattern;

(3) above-mentioned two patterns of recognizer contrast picked-up are when meeting encryption between them

The corresponding relation of setting up during conversion, the expression product is a genuine piece, otherwise is personation

Product;

(4) recognizer shows the result after contrasting.

The generation method of the random grain on product that reaches of the present invention or the packing is: add coloured fibre as information carrier in paper.

The encryption conversion pattern that reaches of the present invention is a two-dimension code.

The present invention is owing to adopt the two-dimension code recognition technology of present widespread use and common CCD pocket hand-held recognizer cheaply, and its advantage is:

1. be difficult to forge:, artificially will control because of fiber is to add at random in the paper-making process

It almost is impossible that each all identical fiber distributes.

2. independent identification: not by any communication network and mainframe computer recognition system.

3. cost of manufacture is extremely low: after the disposable input of equipment, and a 4cm ²Area false proof

Identification pattern is produced cost in batches and is not higher than 0.3 fen of Renminbi.

4. the identification cost is low: except that disposable purchase recognizer, identification is once spent hardly

Any expense.

5. it is a kind of anti-counterfeiting technology that dare to really openly make principle.

6. encrypt the pattern in 2 D code after changing, not only can be used as one of an anti-counterfeiting mark

Individual component part, its can also carry simultaneously product date of manufacture, performance, have

Great deal of related information such as effect phase, producers, reviewer.

Below in conjunction with accompanying drawing and specific embodiment the present invention is described further, embodiment is not as the qualification to protection scope of the present invention.

Fig. 1 is the coloured fibre structural representation that adds in product of the present invention or the packing;

Fig. 2 is the random grain pattern on product of the present invention or the packing;

Fig. 3 is an encryption conversion pattern of the present invention;

As shown in Figure 1, a kind of single multi-color fiber, the long 3mm of fiber for example, diameter 0.05mm dyes blue look with the line segment on the root single 1, and line segment 2 red colourations dye black through section 3.A certain zone at paper in paper-making process adds some fibers, as shown in Figure 2, defining a certain area is anti false information carrier 4, if each the look section 1,2,3 in the every fiber is considered as an information, according to the difference of its color, orientation, coordinate, itself carry a large amount of random character information.Utilize the computer scanning recognition system to its scanning identification, go out a two-dimension code 5 corresponding with it at the other spray printing of above-mentioned random grain pattern after the encryption, as shown in Figure 3, anti-counterfeiting mark just completes.Utilize at last made CCD hand-held scanner that corresponding deciphering is provided with just can independent Direct Recognition authenticity of products.

Anti-counterfeiting mark of the present invention can directly be produced on the label of product itself, on the external packing box of product papery, and be made into label form and be attached on the false proof product that needs, cooperate unique paper technology, also can be used for the false proof of all kinds of securities, currency, invoice, car and boat ticket etc.
