Examples

1. Two-dimensional code generation

Firstly, the invention utilizes an advanced coding algorithm to generate unique and complex two-dimensional codes. The algorithm not only synthesizes a variety of character sets including numbers, letters and Chinese characters, but also specifically designs the data structure to generate complex binary sequences. The sequence construction method considers the characteristics of characters in the aspects of vision and data density, and ensures that the two-dimensional code has high data capacity and is easy to scan and recognize.

The selected character set is not only used for representing basic information of the commodity (such as product name, production lot, production date), but also is combined with a dynamic information segment, which is designed for updating logistics tracking information and product status in real time. For example, the data in the two-dimensional code may be linked to a central database that stores information such as logistics updates, inventory levels, and sales history of the product. Thus, each time the two-dimensional code is scanned, the latest information can be acquired and displayed.

In order to further improve the security, a security encryption layer is embedded in the two-dimensional code. This layer of encryption uses the Advanced Encryption Standard (AES) to ensure that data is not illegally accessed or tampered with during storage and transmission. The encryption mechanism not only protects the sensitive data embedded in the two-dimensional code, such as production details and logistics information, but also ensures that only authorized users and systems can decode and access the information. Furthermore, to combat more advanced counterfeiting techniques, encryption algorithms are regularly updated to maintain the highest level of data security.

The two-dimensional code generated by the advanced coding and encryption technology becomes a data carrier with strong functions and high safety, and provides a comprehensive identity and dynamic information updating platform for commodities.

2. Printing and material of two-dimensional code

In the present invention, the generated two-dimensional code is printed on a specially selected durable and tamper-resistant material using a high precision printing technique. The materials are carefully selected, so that the integrity and the readability of the two-dimensional code can be kept under various environmental conditions. For example, special waterproof paper is suitable for humid environments, while abrasion resistant plastic films are suitable for applications that are often rubbed or exposed to the open air. The material selection not only improves the durability of the two-dimensional code, but also enhances the stability and reliability of the two-dimensional code under different environmental conditions.

During printing, a series of covert security features are introduced to further enhance security. For example, micro-text technology is used to embed text in two-dimensional codes that is nearly invisible to the naked eye, which may contain manufacturing details, copyright information, or other authentication data. In addition, special ink and printing technology are adopted to realize a color gradient effect, and the effect is not easy to notice under common conditions, but can be used for confirming the authenticity of the two-dimensional code under professional equipment. These covert features are difficult for counterfeiters to replicate, thereby greatly improving the security of the two-dimensional code.

In order to further enhance durability, the surface of the two-dimensional code may be coated with a transparent protective film, which can resist scratches, chemical attack and ultraviolet irradiation, so as to ensure that the two-dimensional code remains clear and readable after long-term use. In addition, the materials and printing process selected both conform to environmental standards in view of environmental factors, ensuring that an efficient anti-counterfeiting solution is provided while also minimizing environmental impact.

3. Coding and editing of two-dimensional codes

In the invention, a set of special software system is developed for realizing effective management and updating of information in the two-dimension code. The system has the core function of allowing a user to endow and edit commodity information in the generated two-dimensional code through an intuitive and user-friendly interface.

The software interface design allows for ease and flexibility of operation. The operator can add or modify information in the two-dimensional code through simple drag and drop and click operations. Such information includes basic text descriptions, detailed image presentations, video links, and even interactive elements such as user surveys or feedback forms. The software also supports rich multimedia content editing functions, allowing operators to embed high resolution pictures and videos, as well as other forms of digital content, in two-dimensional codes.

In addition, the software has the ability to link the two-dimensional code with the merchandise database. The link not only allows real-time updating of information in the two-dimensional code, such as real-time inventory status, sales location, market feedback, and product updating, but also automatically adjusts the content in the two-dimensional code according to changes in the database. For example, when the stock level of the product changes or new user feedback is recorded, the relevant information in the two-dimensional code is updated immediately, so that the consumer can always receive the latest information.

The software also incorporates data security and privacy protection mechanisms. All information input or edited by software is encrypted, so that the security of sensitive data in the transmission and storage processes is ensured. The operator can also set the authority control to limit the access and editing to the specific information, further improving the security of the data.

4. Visual recognition and feature extraction

In order to ensure that the two-dimensional code can be accurately and efficiently identified in various environments, an advanced visual identification system is developed in the invention. The system adopts a series of advanced image processing algorithms, aims to optimize the identification process of the two-dimensional code, and ensures that accurate reading can be realized under any illumination condition or scanning angle.

First, the system adopts an edge detection algorithm to identify the boundary and shape of the two-dimensional code. This step is critical to identifying two-dimensional codes in complex background or irregular lighting conditions. By identifying the accurate edge of the two-dimensional code, the system can locate and analyze the data in the two-dimensional code more quickly.

Next, contrast enhancement algorithms are used to improve the visibility of two-dimensional codes, especially in the case of darker or reflective light. According to the algorithm, the brightness and the contrast of the image are adjusted, so that the black and white grids of the two-dimensional code are clearer, and the accuracy and the speed of identification are improved.

In addition, the system incorporates pattern recognition techniques that are capable of recognizing specific patterns and symbols in the scanned image. This applies not only to standard two-dimensional code patterns, but also to the identification of special design elements, such as security marks or corporate logos, that are imparted by the software. This increases the anti-counterfeiting performance while also providing additional brand recognition functionality.

The system also comprises a feature extraction module which is responsible for extracting key information such as coded data and security marks from the scanned two-dimensional code image. This module uses complex algorithms to analyze each pixel in the image to extract all necessary information for subsequent verification and processing.

5. Two-dimensional code verification and time stamp recording

The two-dimensional code verification and time stamping process in the invention is a key step for ensuring the authenticity of the commodity and tracking the history of the commodity. When a consumer or a verifier scans a two-dimensional code on a commodity using a smart phone or a dedicated scanning device, the system automatically triggers a series of verification and recording operations.

First, the system will record the exact time and date of each scan, using the ISO8601 international standard format. The time stamp in this format provides an accurate and uniform way of time recording that facilitates subsequent data analysis and tracking. In addition to the time stamp, the system also records geographic location information of the scanner. This is accomplished by the GPS functionality of the smart device, providing accurate geographic coordinates for each scan. Such information is useful for understanding the circulation of the merchandise and consumer behavior patterns.

After the two-dimensional code is scanned, a background verification module of the system is started immediately. The module compares the scanned two-dimensional code data with original information stored in a database. This comparison process involves decoding of the data, security checking and information checking. If the scanned two-dimensional code data is matched with the information in the database, the system confirms the authenticity of the commodity and provides relevant product information such as production details, historical records and other relevant information for the user. The method not only enhances the confidence of consumers on the authenticity of the product, but also improves the transparency and the trust of brands.

Otherwise, if the scan result does not match the information in the database, the system will immediately issue a warning. This may indicate that the article is counterfeit or has been tampered with illegally. Unmatched scan events may be marked and recorded for further investigation and analysis. This mechanism is critical to combat counterfeiting, protect consumers and brand interests.
