This article introducesAnti-counterfeiting feature of QR codesHow was it achieved.
Ⅰ). QR codes are composed of a matrix of dots. Due to the openness and reproducibility of QR code matrix images, a single QR code does not possess anti-counterfeiting capabilities. However, by leveraging the large data capacity and encryptable content of QR codes, an encrypted identity identifier can be assigned to each product. This code is globally unique and difficult to reverse-engineer.
Ⅱ). QR codes can store a wide range of product information, which is encrypted for security and difficult to copy or steal. Customers scanning the QR code can view numerous details about the product. The format of this message can be tailored to meet the needs of renowned brand sellers. Accuracy in product information authentication can be achieved through reliable verification methods and credible information sources. Due to these functional characteristics of QR codes, they are widely used by anti-counterfeiting companies for the creation and verification of QR code-based anti-counterfeiting labels.
Ⅲ)、The anti-counterfeit QR code utilizes various geometric figures corresponding to binary representations to indicate the text value information. It is automatically identified by detection equipment to complete the automatic resolution of the information content. The basic principle of data encryption for anti-counterfeit QR code is to encrypt the ciphertext file using DES encryption technology, while the DES key is encrypted using RSA encryption technology.
IV) What are the characteristics of anti-counterfeiting QR codes? These QR codes look the same, but each one is actually unique, featuring singularity with no two QR codes containing identical content. These QR codes lack regularity; the content of each QR code does not have periodicity in relation to the others, ensuring the actual effectiveness of the anti-counterfeiting identification.
Ⅴ) Genuine anti-counterfeiting QR codes are QR code styles generated through software with anti-counterfeiting codes. Consumers can scan the QR code to verify the password, thereby obtaining the authenticity and false information of the product.
