The invention provides a racing pigeon foot ring with innovative identification features, and uses the anti-counterfeiting technology on the appearance of the racing pigeon foot ring to produce a kind of pigeon racing ring Anti-fraud system and anti-fraud method. The anti-fraud system provided by the present invention includes the verification system 10 shown in FIG. 1 and the foot ring for racing pigeons (hereinafter referred to as the foot ring) 20 shown in FIG. 2 .

The verification system 10 includes: an image capture unit 12 , a storage unit 14 and a comparison unit 16 . In the present invention, the image capturing unit 12 is used to obtain the random appearance identification feature image of the racing pigeon foot ring 20, and establish the identity information of a racing pigeon's pigeon membership. When the racing pigeon participates in the competition, the random appearance identification feature image of the racing pigeon's ankle ring is captured again to become a comparison data, and the identity information is compared with the comparison data to verify whether the racing pigeon is genuine .

An important technical feature of the present invention is to provide a racing pigeon foot ring 20 with innovative anti-counterfeiting measures. As shown in FIG. The above identification features, the random point pattern 30 is formed on the surface of the foot ring 20 with point particles 32 randomly distributed.

The racing pigeon anklet 20 is for wearing on the feet of the racing pigeon 40, as shown in Figure 5, to identify the identity of the racing pigeon. There is a hole 22 in the center of the ring body of the racing pigeon foot ring 20 for the pigeon feet to penetrate. Racing pigeon foot rings of various shapes or styles can be applied to the present invention, and the style of racing pigeon foot rings is not limited to the drawings of the present invention.

The racing pigeon foot ring 20 of the present invention is made of plastic injection, and the dotted lines 30 are randomly formed during the injection and molding manufacturing process and are exposed on the outer surface of the racing pigeon foot ring 20. Due to the random formation , Therefore, the point pattern 30 of each racing pigeon foot ring is unique, and the point pattern 30 of different racing pigeon foot rings is not the same.

The pigeon ring 20 is injection molded by plastic, and particles are added to the material tube of the injection molding machine to mix with plastic to form a composite plastic, and the mixture is fully mixed by stirring, so that the particles are randomly distributed in the composite plastic. The composite plastic mixed with particles is injected into the mold to make In the pigeon ring, the particles 32 are randomly formed and exposed on the surface of the finished product of the pigeon ring 20 , and the random distribution of the particles 32 becomes the dot pattern 30 . The proportion of the particles 32 in the plastic can be adjusted as required.

The particles 32 can be granular or powdery substances, and the size of the particles 32 is preferably within 0.01 mm ~ 0.3 mm, which can be seen visually, but the particles are not limited to the aforementioned size; the selected particles 32 can be macromolecule material or non-polymer material. In addition, the present invention can use particles 32 of different colors to make the pigeon rings, the particles 32 and the plastic used to make the pigeon rings 20 can be of the same color or different colors, when different colors are used, the particles 32 and the pigeon rings 20 themselves are of different colors. When the material of the particle 32 is different from that of the plastic, even if the particle and the plastic are the same color, the particle 32 can still be seen on the surface of the finished pigeon ring 20 .
