[0019] The present application will be further described below in combination with the accompanying drawings and embodiments.

[0020] Figure 1 The gem identification certificate generation system based on artificial intelligence analysis provided by the present application is shown in the accompanying drawings.

[0021] Please refer to Figure 1 The gem identification certificate generation system based on artificial intelligence analysis provided by the present application comprises four parts: a gem detection data acquisition module, a gem detection data standard management module, a gem data detection large model and a gem digital certificate output module.

[0022] I. Gem detection data acquisition module This module mainly has three parts: a multimedia resource collector (for image collection and storage, mainly commodity surround 3D graph, photo and spectrum photo), a digital resource collector (gem physical information is converted into digital information and stored) and a third party resource collector (digital information and multimedia information are obtained through a third party interface); 1、Multimedia resource collector is used for image collection and storage, mainly the commodity around 3D map, photo and spectral photo; gem has particularity and uniqueness, although the same shape and the same color of gem may look exactly the same, but in fact each gem has its own unique identification, this module is through the large model to record and save the image; large model can accurately record the shape of each gem image, mineral inclusions, the position of the flaw, according to the shape, position, number and type of flaw or inclusion to generate the corresponding code, and then combined with the data coding of digital resource collector to provide to the big data detection model for identification and use; 2、Digital resource collector is used for collecting and storing physical parameters, mainly the physical attribute parameters of the commodity, such as commodity type, origin, processing method, color and size, etc.; this part of data is different from multimedia data, with high similarity, but is an important reference for measuring market value, through the large model to generate corresponding code and multimedia collector data code together to provide to the big data detection model for identification and use; 3、The third party resource collector mainly obtains multimedia and physical parameter information transmitted by the third party interface, the interface will have a source field and define the data format (such as commodity type, size, origin, processing method, commodity picture field); after white list and interface information security check, the data meeting the data format requirements are transmitted to the multimedia resource collector and digital resource collector for processing.

[0023] II. Gem detection data standard management module This module mainly has two parts: gem data standard dictionary library (defines various standards in the system) and gem data node tree management module (configure and manage digital information of different types of gem); 1、Gem data standard dictionary library is the basis of the whole system, which includes all gem identification standards (the standard mainly refers to the corresponding national standard of China), market value evaluation standard (the standard mainly refers to the collected market price), similarity threshold range standard (this part is compiled according to historical data, especially a large number of imported gem data, and according to the requirements of the supervising customs) and data entry standard, etc.; The similarity threshold range standard can be set as follows: similarity value between 80-90 is defined as possible similarity, 90-95 is defined as similarity, and above 95 is defined as extremely similar. Possible similarity will be checked, with a probability of ten to two; similar will also be checked, with a probability of five to three; extremely similar will be checked every time.

[0024] 2、Gemstone data node tree management module mainly records the additional node information and corresponding node fields (including multimedia parameters and physical parameters) of each gemstone, which can enrich the content of gemstone ai digital certificate. Currently, it records mineral information (country of origin, mine and time), customs information (customs declaration number and time), and processing information (processing country, processing content and time).

[0025] The gemstone data node tree management module supports dynamic expansion of node structure, allows users to customize node attributes according to the characteristics of gemstone categories, and can mine and model the implicit relationship between nodes through graph neural network (GNN), realizing deep analysis of gemstone traceability and quality correlation. For example, the gemstone data node tree management module supports users to dynamically add and modify node attributes through graphical interface, and uses graph convolution network (GCN) to model the complex relationship between gemstone nodes (such as the implicit correlation of origin-quality-market price), output visual knowledge graph, and assist appraisers to make more comprehensive judgments.

[0026] III. Gemstone data detection large model This module mainly has three parts: gemstone digital AI large model (algorithm model calculation) and gemstone algorithm basic configuration module (management of various coefficients and weighting content in algorithm) and big data discrimination verification module (discrimination confirms data similarity to prevent gemstone repeated identification); 1. The large-scale digital AI model for gemstones primarily analyzes the multimedia and physical parameters of gemstones to evaluate their market value. Multimedia parameters reveal surface flaws and inclusions, with the size and number of these flaws and inclusions affecting the value. However, certain types of gemstones require special processing. For example, amber containing biological material may be more valuable, while air bubbles decrease its value. Another type is star sapphire, where the internal texture is specially processed using multimedia images; the higher the proportion of starlight within the sapphire, the higher its value. However, the shape and form of the starlight cannot currently be processed by the large model and require human intervention for scoring. The same applies to refractive index; gemstones with a high refractive index are more dazzling and naturally more valuable. Physical parameters are relatively easy to score using large-scale models, but unlike other standardized products, the value of gemstones is influenced by a variety of factors. For example, Burmese rubies are more valuable than those from other origins, and Thai-processed rubies and sapphires are more valuable than those processed in other countries. Similarly, even within Brazilian tourmaline, different varieties (common tourmaline and Padparadscha) can have vastly different values. And for rubies of the same quality, pigeon blood red is much more expensive than other colors. While ideal multimedia parameters for a gemstone can make it seem more valuable, this is often not the case. Historical data shows that physical parameters have a greater impact on value, although multimedia data also plays a significant role. Therefore, large-scale models need to carefully control the proportions when evaluating value. Another major advantage of large-scale models is the ability to complete evaluations and issue certificates very quickly. What used to take at least half an hour can now be completed in seconds to minutes.

[0027] Algorithm details: GEMAI = (0.15×T + 0.20×V + 0.18×RI + 0.22×C + 0.12×O + 0.08×I +0.05×P) × CF iT is the value coefficient for gemstones, graded according to market scarcity. Diamond: 1.0, Ruby / Sapphire: 0.95, Emerald: 0.90, Chrysoberyl Cat's Eye: 0.88, Spinel: 0.85, Other rare gemstones (such as tourmaline): 0.8, Common semi-precious stones: 0.6.

[0028] ii.V is the volume factor = log10(volume mm³) / 2 × cutting correction factor (cutting correction factor: EX cutting = 1.2, VG ​​cutting = 1.0, others = 0.8, refer to the national 4C standard). Carat premium: When the weight is ≥1 carat, the V value × the extra value. According to the weight ratio, the extra value is 1.1 for 1-2 carats, 1.3 for 2-3 carats, and so on.

[0029] iii.RI is the refractive index coefficient RI = (measured RI - 1.3) / (2.5 - 1.3) + dispersion value x 0.2; the dispersion value is normalized (e.g. diamond 0.044, sapphire 0.018, ruby 0.018, emerald 0.017, and emerald 0.014).

[0030] iv.C is the color score coefficient, which needs to be supported by high-spectral quantitative data Color belongs to rare color (e.g. Paraiba blue, pigeon blood red): C = 1.0 Saturation > 80% and hue positive: C = 0.8 + (lightness% / 100) x 0.2 C = 0.5 + (saturation% / 200).

[0031] v.O is the origin coefficient (associated with the type of gemstone) Taking sapphire as an example, the origin premium reference is: Kashmir: 1.0, Myanmar: 0.95, Colombia: 0.9, Russia: 0.85, and other well-known producing areas: 0.7.

[0032] vi.I is the inclusion system number I = 1 - (number of inclusions x 0.05 + maximum size mm x 0.3) + special inclusion bonus Special inclusion bonus: e.g. chrysoberyl horse-tail inclusion +0.2, and davis structure +0.1.

[0033] vii.P is the processing method (associated with the type of gemstone) Taking sapphire as an example: with burning: 0.9, without burning: 1.0.

[0034] viii.CF is the correction mark CF = 1 + certificate bonus (GIA + 0.15, other authorities + 0.1) + optical effect (fire / catch / cat eye + 0.2); GIA certificate is a diamond grade certificate issued by the Gemological Institute of America (GIA). Other authorities such as GRS / GUILD / Gübelin / SSEF, etc. will be referred to, because the multimedia information and physical information of the identification agency are relatively accurate.

[0035] The public result (score 0-1, ≥0.9 is a collection level), the gemstone identification certificate generation system adopting the present application scores the result as shown in Figure 2 .

[0036] Preferably, the gemstone digital AI large model adopts a multi-modal fusion architecture based on Transformer, which can simultaneously encode high-resolution images, spectral data, 3D point cloud data and physical parameters, and realize semantic alignment between features through cross-modal attention mechanism (Cross-Modal Attention), to improve the accuracy and robustness of identification results, especially to significantly improve the identification and evaluation accuracy of rare gemstones (such as chameleon diamonds, alexander varicolored stones, etc.).

[0037] 2. The gemstone algorithm basic configuration module mainly adjusts and reallocates the basic values and proportions of various parameters in the algorithm. It can choose to start the calculation and evaluation again, or it can choose to repair the historical data.

[0038] 3. The big data identification and verification module mainly identifies the multimedia and digital coding, mainly compares the generated coding in the historical database for similarity, when the similarity exceeds a certain percentage, it will be prewarned and separately screened out for subsequent manual confirmation. Generally set at 95%, historical data correction is a batch operation on the original database, which generally needs manual operation and leaves operation logs.

[0039] Four, gemstone digital certificate output module This module mainly has two parts: terminal digital certificate display module (gemstone digital certificate display on terminal, including 3D photo and various digital information) and terminal digital certificate security authentication module (interface security authentication and identity authentication).

[0040] 1. The terminal digital certificate display module mainly displays the gemstone digital certificate, including the picture of the gemstone, the basic physical parameters of the commodity, part of the node information on the supply chain, and the evaluation information given by the large model; the terminal digital certificate display module integrates augmented reality (AR) visualization components, users can scan the digital certificate QR code through mobile terminal, real-time superimposed display of gemstone three-dimensional model, optical special effect simulation (such as starlight, cat eye effect) and visualization labeling of key physical parameters.

[0041] 2. The terminal digital certificate security authentication module is used for the security authentication of digital certificate, protects the daily login times of the same IP address, prevents data crawling, firewall security settings, third-party query interface whitelist, and interface call encryption protection, etc.

[0042] 3. The terminal ownership management module primarily allows terminal holders to bind and authenticate digital certificates through real-name authentication, transferring ownership to themselves. Unbound digital certificates can be directly bound using an ID card for the first time. After binding, the digital certificate belongs to that user, who can view all information on the digital certificate and has the right to hide or display relevant information, as well as enter transaction information. Other users cannot bind the digital certificate, view bound information, or information the holder does not wish to display. For ownership transfer to occur, the original holder needs to actively trigger the ownership transfer process, temporarily transferring the digital certificate to the new holder's account. After real-name authentication, the transfer is complete. The new holder can enter transfer notes, using the digital certificate as a digital transaction credential. The transfer is completed after confirmation by the original holder. Related ownership transfer records will also be used as traceability nodes for blockchain record authentication.

[0043] 4. A blockchain-based certificate storage and traceability module: Each generated digital certificate uses asymmetric encryption technology to generate a digital signature, and its hash value is written to a permissioned blockchain (such as Hyperledger Fabric). All queries and verification operations on this certificate are recorded through smart contracts, ensuring data immutability and auditable operations. In other words, any modification or query of the certificate requires authorization verification and operation recording through smart contracts, achieving fully traceable and non-repudiable data security management. The blockchain authentication result is as follows: Figure 3 As shown, the generated digital certificate and directory information are as follows: Figure 4 As shown.

[0044] The gemstone identification certificate generation system of this invention performs digital authentication and grading of each gemstone entirely through a large-scale model, possessing professional identification knowledge and unique characteristics specific to the gemstone industry. It incorporates multiple technical means, including multimodal artificial intelligence analysis, dynamic node management, augmented reality display, and blockchain evidence storage, into the traditional gemstone identification process, offering the following significant advantages: 1. The data sources are legal and the results are objective. The weighted correlation coefficients are derived from actual market sales and value. That is, the coefficients before T, V, RI, C, O, I, P, and CF are based on a comprehensive consideration of various gemstones in the market and the factors that affect their prices. Relevant information companies will provide suggestions. 2. By using multimodal fusion and attention mechanisms, the limitations of traditional single data source analysis are overcome, significantly improving the identification accuracy in complex scenarios; 3. Supports dynamically expandable data nodes and graph analysis. Utilizes scalable data node trees and graph neural networks to achieve deep correlation analysis of unstructured data, enhancing system flexibility and analytical depth; 4. Provide immersive AR certificate display to enhance the interactivity and user experience of digital certificates; 5. The authenticity and traceability of the guarantee are ensured by blockchain technology.

[0045] Although the present application has been disclosed with reference to preferred embodiments, it is not intended to limit the present application, and any person skilled in the art, without departing from the spirit and scope of the present application, can make some modifications and improvements, and therefore the scope of protection of the present application is defined by the claims.
