Technical characterictic of the present invention is non-obvious, and its effect must could produce after simultaneously comprehensive following five excellent skills:
1, much no matter will select zone definitions to have artificially, fiber in the zone has the more, how complicated fiber arranged evenly has, utilize the producer and personator's information asymmetry, only getting wherein a fiber stores, the personator then must imitate fibers all in the selection zone of setting and distribute if will duplicate.
2, no matter a fiber shape be the straight line or the curve of complicated bend, as long as with on the fiber arbitrarily the position coordinates of any deposit computer system in, the personator be if will duplicate, then the accurate curve shape of the whole fiber of imitation.
3, taked only one query effective measures of a stack features, thereby stopped the possibility of once only being duplicated this group random character by the just a large amount of repetitions of personator of inquiry back.
4, in order to satisfy the repeatedly effectively inquiry of a product, can store many group anti-counterfeiting information simultaneously, computer system of every inquiry is called one group of anti-counterfeiting information and is checked, and computer system this group anti-counterfeiting information that cancels is used up by inquiry until many groups anti-counterfeiting information then.
5, with the position coordinates of any point on the fiber (as end points) fundamental as random character, the positive effect that this skill is brought is: any point (as end points) position coordinates is the most basic random character unit of fiber pattern on (1) fiber, and its energy fullest embodies the stochastic distribution of fiber pattern the most accurately; (2) any point (particularly end points) is visually the most remarkable on the fiber, and it is consuming time the shortest only to check the position of a point, has made things convenient for the inquiry; (3) some position coordinateses just can be described very accurately with voice or literal, thus can only need the voice description of phone or the character message breath of mobile phone to get final product, thus can break away from loaded down with trivial details expensive online and image transmission inquiry mode; The memory space minimum that the position coordinate data of (4) points takies in computer system has been saved the storage space of computer system; The collection of the position coordinate data of (5) points can for example can be taked manually to copy not by shooting or scanning device, and these characteristics have not only reduced the equipment input, more this technology can be popularized to medium-sized and small enterprises to have realistic meaning.
So effect of the present invention is fairly obvious, it has reduced the storage space of computing machine, shortens the time that inquiry is checked, improved cost of reproduction, when particularly only any end points coordinate of a fiber being described, degree of accuracy can be very high, and inquiry's identification also can be very careful.
