A chaotic graphic tag-based anti-counterfeit system and method. Feature information of a chaotic graphic tag is extracted by utilizing an image recognition technique. An ID of the chaotic graphic tag, the feature information thereof, and information of a target object associated with the tag are saved to cloud data. The feature information of the chaotic graphic tag is calculated by utilizing same graphic recognition technique. The ID of the chaotic graphic tag is utilized to find feature information of a corresponding tag in the cloud data. A determination is made, on the basis of the similarity of the two pieces of feature information, on whether or not a match is found; if yes, then information of the target object associated with the current tag is returned; and if not, then a match failure is returned. The system comprises: a tag information entry system and a tag verification system. This utilizes irreproducible naturally chaotic structured graphics as anti-counterfeit tags, utilizes image scanning, computer vision, graphic feature extraction, and massive graphics retrieval technique to implement anti-counterfeiting, and provides difficult-to-duplicate tags, fast and accurate identification, ease of use, and broad applicability. |
