Description

Ultramicro-feature anti-counterfeiting chip and production method and identification method thereof

Technical Field

The invention relates to an ultra-micro characteristic anti-counterfeiting chip which is suitable for anti-counterfeiting industry.

Background

The existing anti-counterfeiting products are usually manufactured into labels and are stuck on products or packing materials, the area is generally larger than 1 square centimeter, and anti-counterfeiting marks containing random characteristics are usually identified by acquiring mark images through a mobile phone camera. Such a label form and authentication method have the following problems:

firstly, labels are often incompatible with products or packages, so that the attractiveness is affected, and some products cannot be used by being stuck with labels; secondly, the effective service cycle of the label is short, the adaptability and the weather resistance to severe environment are poor, the label is often stained after the product is used and cannot be identified and used, and the requirement that a user wants to identify the product for a long time and track, maintain and obtain information cannot be met; thirdly, the identification of the anti-counterfeit label containing the random feature usually needs to obtain and identify the fine anti-counterfeit feature in the label, such as: the size of fine features on some anti-counterfeiting labels is usually smaller than 0.05 mm or even lower, and the fine feature images on the anti-counterfeiting labels are obtained by a mobile phone camera and are identified, so that the anti-counterfeiting labels are inconvenient and unreliable in practical use. Because the mobile phone camera needs to have higher resolution and macro imaging quality to acquire the fine random feature image, the existing mobile phones have numerous brands and models, and the imaging quality of the camera is uneven, so that it is impossible to ensure that each mobile phone can acquire clear and accurate fine feature images during identification. Even if the same mobile phone has very good imaging quality, different users can not shoot the same anti-counterfeit label under different light rays, distances, angles and hand-held stability, and the clear and accurate image can not be obtained during each authentication. The fine features in the acquired image are difficult to avoid fuzzy and unclear, and some fine features even losing the features or the feature images are distorted, so that accurate results cannot be ensured to be obtained in each identification, true identification can be identified as false, false identification can be identified as true, or the identification result cannot be obtained, which is a fatal defect for anti-counterfeiting identification and can generate negative effects, and the anti-counterfeiting method established on the basis is unreliable and does not meet the requirements of the anti-counterfeiting industry.
