Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a transaction data processing method of a gold recovery intelligent terminal. Background Art

[0002] With the rapid development of Internet of Things technology, the popularity of smart devices and information interconnection have become increasingly close, providing a basis for real-time monitoring, data collection and analysis. The rise of this technology has brought unprecedented opportunities to the gold recycling industry. The integration of financial technology and the Internet of Things has begun to take root in the gold recycling industry. The emergence of smart terminals has made the recycling process more convenient and efficient. Customers can evaluate and trade gold through smart terminals without having to go through cumbersome offline processes. These terminals are equipped with high-precision sensors and image recognition technology, which can quickly and accurately identify and evaluate gold. With the development of artificial intelligence and big data technology, the transaction data processing methods of smart terminals have also been further optimized. Machine learning algorithms can predict gold price trends and market demand based on historical data and real-time conditions, providing decision support for recyclers. At the same time, the application of blockchain technology ensures the security and transparency of transaction data and prevents information tampering and fraud. However, the current traditional payment methods are usually relatively single, which limits user choices. At the same time, there is a problem of lax identity authentication, which can easily lead to transaction security risks, resulting in low efficiency and security of transactions. Summary of the invention

[0003] Based on this, it is necessary to provide a transaction data processing method for a gold recycling intelligent terminal to solve at least one of the above technical problems.

[0004] To achieve the above purpose, a transaction data processing method of a gold recovery intelligent terminal is provided, the method comprising the following steps:

[0005] Step S1: Performing quality inspection on the gold to be recycled by the user through the gold recycling intelligent terminal to obtain the quality data of the gold to be recycled by the user;

[0006] Step S2: obtaining the real-time gold transaction price; using machine learning methods to predict the price of the user's gold to be recycled based on the real-time gold transaction price, generating an estimated gold recycling price and displaying it on the smart terminal page, generating a gold recycling estimated price interface;

[0007] Step S3: confirming the user's payment method according to the gold recycling estimated price interface, and generating user payment method data, wherein the user payment method data includes the user's first payment method data and the user's second payment method data;

[0008] Step S4: Performing real-name verification on the user based on the user's payment method data to generate user identity verification data;

[0009] Step S5: Determine whether the user identity authentication data is passed. When the user identity authentication is passed, conduct a secondary quality inspection on the gold to be recycled, generate the final price of gold recycling and display it on the smart terminal page, and generate the final price interface of gold recycling; perform user confirmation based on the final price interface of gold recycling. When the user confirms, the transaction background pays the gold recycling amount to the user to complete the gold recycling transaction.

[0010] The present invention performs quality inspection on the gold to be recycled through an intelligent terminal, and performs price forecasting based on the real-time gold transaction price. This can provide accurate gold quality and estimated recycling price information, help users understand their gold value, and make recycling decisions. According to the estimated recycling price interface, the user can confirm and select the payment method, including the first payment method and the second payment method. Such a selection right can meet the payment needs and preferences of the user and improve the user's satisfaction. Real-name verification based on the user's payment method data can ensure the security and credibility of the transaction. This step can prevent fraud and identity theft and protect the interests of the user. After the user's identity verification is passed, the quality of the gold to be recycled is secondary inspected, and a final price interface is generated. The user can confirm the final recycling price according to the interface to ensure the transparency and fairness of the transaction. When the user confirms the final recycling price, the transaction backend pays the gold recycling amount to the user to complete the gold recycling transaction. This process simplifies the transaction process and improves the efficiency and convenience of the transaction. Therefore, the present invention improves the efficiency and security of the transaction through real-time price forecasting, multiple payment methods, identity verification and secondary quality inspection.

[0011] The beneficial effect of the present invention is that through the quality detection and price estimation of the intelligent terminal, the user can clearly understand the quality and expected price of the gold to be recycled. The price prediction based on machine learning can more accurately estimate the gold recovery price, improve the fairness and accuracy of the transaction, and meet the user's demand for price information. The real-name verification of the user's payment method data improves the security and reliability of the transaction and ensures the authenticity and legitimacy of the user's identity during the transaction. The secondary detection of gold quality and the final price confirmation guarantee the quality and accuracy of the transaction, provide users with reliable gold recovery services, and enhance the user's sense of trust and satisfaction. The timeliness and accuracy of the transaction backend to pay the gold recovery amount to the user improves the efficiency and convenience of the transaction and promotes the development and prosperity of the gold recovery market. Therefore, the present invention improves the efficiency and security of the transaction through real-time price prediction, multiple payment methods, identity authentication and secondary quality detection.

[0020] To achieve this, please refer to Figures 1 to 4 , a transaction data processing method of a gold recovery intelligent terminal, the method comprising the following steps:

[0021] Step S1: Performing quality inspection on the gold to be recycled by the user through the gold recycling intelligent terminal to obtain the quality data of the gold to be recycled by the user;

[0022] Step S2: obtaining the real-time gold transaction price; using machine learning methods to predict the price of the user's gold to be recycled based on the real-time gold transaction price, generating an estimated gold recycling price and displaying it on the smart terminal page, generating a gold recycling estimated price interface;

[0024] Step S4: Performing real-name verification on the user based on the user's payment method data to generate user identity verification data;

[0025] Step S5: Determine whether the user identity authentication data is passed. When the user identity authentication is passed, conduct a secondary quality inspection on the gold to be recycled, generate the final price of gold recycling and display it on the smart terminal page, and generate the final price interface of gold recycling; perform user confirmation based on the final price interface of gold recycling. When the user confirms, the transaction background pays the gold recycling amount to the user to complete the gold recycling transaction.

[0026] The present invention performs quality inspection on the gold to be recycled through an intelligent terminal, and performs price forecasting based on the real-time gold transaction price. This can provide accurate gold quality and estimated recycling price information, help users understand their gold value, and make recycling decisions. According to the estimated recycling price interface, the user can confirm and select the payment method, including the first payment method and the second payment method. Such a selection right can meet the payment needs and preferences of the user and improve the user's satisfaction. Real-name verification based on the user's payment method data can ensure the security and credibility of the transaction. This step can prevent fraud and identity theft and protect the interests of the user. After the user's identity verification is passed, the quality of the gold to be recycled is secondary inspected, and a final price interface is generated. The user can confirm the final recycling price according to the interface to ensure the transparency and fairness of the transaction. When the user confirms the final recycling price, the transaction backend pays the gold recycling amount to the user to complete the gold recycling transaction. This process simplifies the transaction process and improves the efficiency and convenience of the transaction. Therefore, the present invention improves the efficiency and security of the transaction through real-time price forecasting, multiple payment methods, identity verification and secondary quality inspection.

[0027] In the embodiment of the present invention, reference Figure 1 The above is a schematic flow chart of the steps of a transaction data processing method of a gold recovery intelligent terminal of the present invention. In this example, the transaction data processing method of a gold recovery intelligent terminal includes the following steps:

[0028] Step S1: Performing quality inspection on the gold to be recycled by the user through the gold recycling intelligent terminal to obtain the quality data of the gold to be recycled by the user;

[0029] In the embodiment of the present invention, by ensuring that the gold recovery intelligent terminal device is in good condition, including hardware devices and software systems. Ensure that the device has sufficient performance and accuracy to perform quality inspection. The user places the gold sample to be recycled on the gold recovery intelligent terminal and starts the inspection program. Use the terminal's built-in sensors, cameras and other devices to scan and inspect the gold sample. The sensor can measure the weight, density, purity and other characteristics of the sample, and the camera can capture the appearance characteristics of the sample. The data obtained from the sensor and the camera is transmitted to the processing unit of the intelligent terminal. The quality inspection algorithm is run on the intelligent terminal to analyze and process the data of the gold sample, involving steps such as data filtering, feature extraction, and pattern recognition. The quality inspection results are output in the form of data, specifically a report, including the quality parameters of the gold sample, such as weight, purity, etc., or digital data, such as a CSV file or an API interface. The quality inspection results are displayed to the user, usually in a visual form, such as a chart, numbers, etc.

[0030] Step S2: obtaining the real-time gold transaction price; using machine learning methods to predict the price of the user's gold to be recycled based on the real-time gold transaction price, generating an estimated gold recycling price and displaying it on the smart terminal page, generating a gold recycling estimated price interface;

[0031] In an embodiment of the present invention, real-time gold trading prices are obtained by using financial data sources or APIs. These data sources are specifically financial market exchanges, gold trading platforms or financial data providers. The obtained real-time gold trading price data is preprocessed, including data cleaning, denoising and formatting operations. Features, such as daily average price, price fluctuation, trading volume, etc., are extracted from the real-time price data and used as input features for the machine learning model. A machine learning algorithm, such as a regression algorithm (such as linear regression, ridge regression, random forest regression, etc.), is used to train a price prediction model based on historical gold trading price data. The training set and the test set are divided, and the model is trained and evaluated to ensure that the model has good generalization ability and prediction accuracy. When the user places the gold sample to be recycled on the smart terminal, the price prediction function is triggered. The feature data of the gold to be recycled is input into the trained machine learning model to perform price prediction. The predicted estimated price of gold recovery is displayed on the smart terminal page to generate a gold recovery estimated price interface. The predicted price is specifically displayed in digital or graphical form. The real-time gold trading price is updated regularly (for example, every once in a while) to ensure that the price data used by the model is kept up to date. Provide user feedback, including explanation of the predicted price, accuracy evaluation, etc. Users can decide whether to recycle gold or take other actions based on the predicted price.

[0032] Step S3: confirming the user's payment method according to the gold recycling estimated price interface, and generating user payment method data, wherein the user payment method data includes the user's first payment method data and the user's second payment method data;

[0033] In an embodiment of the present invention, the gold recovery estimated price interface is displayed on the smart terminal page, including the estimated price of the gold to be recovered and the payment method options. After browsing the gold recovery estimated price interface, the user selects the preferred payment method, including cash payment, credit card payment, mobile payment or other electronic payment methods, such as payment through a smart phone, including Apple Pay, Google Pay and Samsung Pay, such as PayPal, Venmo and Skrill, which allow users to store funds and make online or offline payments. According to the payment method selected by the user on the gold recovery estimated price interface, the corresponding user payment method data is generated. The user payment method data includes the user's first payment method data and the second payment method data, in case the user's preferred payment method is not available. The user payment method data is recorded in the system for subsequent payment processing and tracking. Specifically, the user payment method data is stored in the database to ensure data security and reliability. After the user confirms the payment method, the user is required to confirm the selection again to ensure correctness and accuracy. After confirming the payment method, the system can display a confirmation message or further payment details to complete the transaction process.

[0034] Step S4: Performing real-name verification on the user based on the user's payment method data to generate user identity verification data;

[0035] In the embodiment of the present invention, the payment method data selected by the user is obtained from step S3, including the user's first payment method and the second payment method. According to the payment method selected by the user, the corresponding real-name verification process is started, including the following methods: If the user chooses credit card payment, the user's identity is verified by credit card information, such as name, card number, expiration date and CVV code, etc. If the user chooses mobile payment, it is verified by the bound mobile phone number or other identity information. If the user chooses cash payment, the user may be required to provide an identity card or other identity information for verification. According to the payment method selected by the user, the corresponding real-name verification process is started, including the following methods: If the user chooses credit card payment, the user's identity is verified by credit card information, such as name, card number, expiration date and CVV code, etc. If the user chooses mobile payment, it is verified by the bound mobile phone number or other identity information. If the user chooses cash payment, the user may be required to provide an identity card or other identity information for verification. The generated user identity verification data is recorded in the system for subsequent payment processing and transaction tracking. The storage of user identity verification data shall comply with relevant privacy and data protection regulations to ensure the security and confidentiality of user information. During the real-name verification process, the system can interact with the user, prompting the user to provide necessary identity information, such as name, date of birth, ID number, etc., and ensure that the user understands and confirms. If the verification is successful, the system can display a confirmation message or continue the payment process; if the verification fails, the system can prompt the user to re-enter or select another payment method.

[0036] Step S5: Determine whether the user identity authentication data is passed. When the user identity authentication is passed, conduct a secondary quality inspection on the gold to be recycled, generate the final price of gold recycling and display it on the smart terminal page, and generate the final price interface of gold recycling; perform user confirmation based on the final price interface of gold recycling. When the user confirms, the transaction background pays the gold recycling amount to the user to complete the gold recycling transaction.

[0037] In the embodiment of the present invention, after receiving the user identity authentication data, the system performs identity authentication comparison and verification to confirm whether the user identity is legal and valid. If the user identity authentication is passed, the system will proceed to the next step; if the verification fails, the corresponding prompt information will be displayed to the user and the transaction process will be terminated. After the user identity authentication is passed, the gold to be recycled is subjected to secondary quality inspection, which involves the use of a gold recycling intelligent terminal or other professional equipment for quality inspection. After the inspection is completed, the final quality data of the gold recycling is obtained, including information such as the purity and weight of the gold. Based on the final gold quality data, the system calculates the final price of the gold recycling and displays it on the intelligent terminal page. A gold recycling final price interface is generated to display the final recycling price to the user. After browsing the gold recycling final price interface, the user confirms whether to accept the final recycling price. The user can choose to confirm the transaction or cancel the transaction. When the user confirms the transaction, the transaction backend system pays the gold recycling amount to the user to complete the gold recycling transaction. The payment process involves steps such as the user providing payment information and password confirmation to ensure payment security and legality.

[0038] Preferably, step S1 comprises the following steps:

[0039] Step S11: Performing quality inspection on the user's gold to be recycled through the gold recycling intelligent terminal to obtain the user's initial quality data of the gold to be recycled;

[0040] Step S12: Cleaning the user's initial gold quality data to be recycled to generate cleaned gold quality data to be recycled;

[0041] Step S13: Filling missing values ​​in the user's gold quality cleaning data to be recycled, and generating the user's gold quality filling data to be recycled;

[0042] Step S14: using the maximum-minimum standardization method to standardize the user's gold mass filling data to be recycled, and generate the user's gold mass data to be recycled.

[0043] The present invention can improve the accuracy and completeness of data and reduce the possibility of erroneous analysis by performing quality inspection, cleaning and filling of data. Standardized data makes them more consistent in value, which makes it easier to compare and analyze. Cleaned and standardized data is easier to understand and interpret, which can help make more informed decisions, such as determining the quality grade and pricing of gold. Through automation and standardized processing, time and labor costs can be saved and processing efficiency can be improved.

[0044] As an example of the present invention, refer to Figure 2 As shown, in this example, step S1 includes:

[0045] Step S11: Performing quality inspection on the user's gold to be recycled through the gold recycling intelligent terminal to obtain the user's initial quality data of the gold to be recycled;

[0046] In the embodiment of the present invention, by ensuring that the gold recovery intelligent terminal is in normal working condition, all necessary sensors and equipment have been correctly installed and connected. Collect the user's gold samples to be recovered, ensure that the source of the samples is reliable, and prepare for testing. Place the gold samples to be recovered in the gold recovery intelligent terminal and start the quality inspection program. The program may include the use of various sensors and technologies to detect the physical and chemical properties of gold, such as weight, purity, composition, etc. During the quality inspection process, the system automatically records the detected data, including various indicators and quality characteristics of gold. Ensure that the data records are accurate. Based on the quality inspection results, generate the quality data of the user's initial gold to be recovered, including but not limited to information such as weight, purity, and color.

[0047] Step S12: Cleaning the user's initial gold quality data to be recycled to generate cleaned gold quality data to be recycled;

[0048] In the embodiment of the present invention, the structure, format and content of the data are understood by carefully reviewing the user's initial gold quality data to be recycled. This includes checking whether the data has missing values, outliers, duplicate values ​​and other problems. Identify and process missing values ​​in the data. Missing values ​​can be processed by filling, deleting or interpolating, and the specific method depends on the nature of the missing values ​​and the characteristics of the data. Detect and process outliers in the data. Outliers may affect the accuracy of the data and the analysis results, so it is necessary to identify and perform appropriate processing, such as deleting or correcting outliers. Identify and process duplicate values ​​in the data. Duplicate values ​​may cause deviations in the data analysis results, so it is necessary to detect and delete duplicate values ​​to ensure that each data is unique.

[0049] Step S13: Filling missing values ​​in the user's gold quality cleaning data to be recycled, and generating the user's gold quality filling data to be recycled;

[0050] In an embodiment of the present invention, by checking the cleaned data, the missing values, i.e., blank or unknown values, are identified. An appropriate filling strategy is determined based on the characteristics of the data and the analysis requirements. Common filling methods include mean filling, median filling, mode filling, interpolation filling, etc. According to the selected filling strategy, the missing values ​​in the data are filled. This can be achieved through programming or data processing software. For continuous data, statistics such as mean or median can be used for filling; for categorical data, mode can be used for filling. After filling is completed, the data is verified to ensure that the filled data is consistent with the original data and that the distribution of the filled data is as expected.

[0051] Step S14: using the maximum-minimum standardization method to standardize the user's gold mass filling data to be recycled, and generate the user's gold mass data to be recycled.

[0052] In the embodiment of the present invention, the principle of maximum-minimum standardization is understood. This method linearly scales the data to a specific range (usually [0,1] or [-1,1]), where the minimum value is mapped to 0 and the maximum value is mapped to 1. Ensure that the steps of filling missing data values ​​have been completed and the quality filling data of gold to be recovered is generated. These data may include various indicators of gold, such as weight, purity, color, etc. Calculate the maximum and minimum values ​​of each feature to be standardized (such as weight, purity, etc.). These values ​​will be used in the standardization calculation. Perform maximum-minimum standardization calculation on each feature, and the specific calculation formula is: X standardization = X maximum - X minimum / XX minimum; where X is the original value, X minimum and X maximum are the minimum and maximum values ​​of the feature, respectively. Generate the quality data of gold to be recovered by the user based on the calculated standardized values. These data will be standardized within a specific range to facilitate subsequent analysis and comparison.

[0053] Preferably, the payment method of the user confirmed according to the gold recycling estimated price interface includes:

[0054] Collecting the user's first payment method data based on the first touch area of ​​the gold recycling estimated price interface;

[0055] Collect the user's second payment method data based on the second touch area of ​​the gold recycling estimated price interface;

[0056] The first payment method is bank card payment, and the second payment method is digital wallet payment.

[0057] The present invention provides a variety of payment options, including traditional bank card payment and digital wallet payment. This diversity can meet the different payment needs and preferences of users, and improve the convenience and satisfaction of users. Both bank card payment and digital wallet payment have a certain degree of security. Bank card payment usually requires users to enter information such as bank card number, validity period and security code, while digital wallet payment uses encryption technology and identity authentication to protect the user's funds. Users can choose a payment method that suits them according to their needs and trust level, thereby improving the security of the payment process. By collecting payment method data in the touch area of ​​the gold recycling estimated price interface, users can directly select payment methods on the smart terminal without additional steps and transfers, simplifying the payment process and improving the convenience and efficiency of payment. Users participating in the payment method selection process can increase their sense of participation and control over the transaction. This increase in participation can enhance users' trust and satisfaction with the transaction and promote them to participate more actively in gold recycling transactions.

[0058] In an embodiment of the present invention, two touch areas are set on the gold recycling estimated price interface, which are used to collect the user's first payment method data and second payment method data respectively. The first touch area and the second touch area are clearly displayed on the interface, and the corresponding payment methods are marked, such as "bank card payment" and "digital wallet payment". When the user touches the first touch area, the system records the payment method selected by the user as the first payment method data. When the user touches the second touch area, the system records the payment method selected by the user as the second payment method data. Clear instructions are provided on the interface to inform the user how to select a payment method. Specifically, text descriptions or icons are used to indicate where the user touches to select a payment method. After the user touches the touch area, the system can confirm the user's selection operation through interface feedback (such as color changes, check marks, etc.). After confirming the user's selection, the system records the corresponding payment method data.

[0059] Preferably, performing real-name verification on the user based on the user's payment method data includes:

[0060] Perform universal real-name identity authentication on users and generate universal user verification data, where universal verification includes identity card verification and mobile phone number verification;

[0061] Performing difference verification on the user based on the user's payment method data, and when confirming that the user's payment method data is the user's first payment method data, performing contactless biometric factor verification on the user to generate the user's first characteristic verification data;

[0062] When it is confirmed that the user payment method data is the user's second payment method data, the user is digitally verified to generate the user's second characteristic verification data;

[0063] The user is double-authenticated using the user's first characteristic verification data or the user's second characteristic verification data and the user's universal verification data to generate user identity verification data.

[0064] The present invention can ensure the authenticity and validity of the identity information provided by the user by performing universal real-name identity verification, including identity card verification and mobile phone number verification. This verification can prevent the use of false identities and improve the security and reliability of transactions. Differential verification is performed according to the user's payment method data, non-contact biometric factor verification is performed on the user's first payment method data, and digital verification is performed on the user's second payment method data. This differential verification can increase the security of transactions and prevent the abuse of payment methods and the occurrence of fraudulent behaviors. Using the user's characteristic verification data and universal verification data for dual authentication can further ensure the authenticity of the user's identity and the security of transactions. This dual authentication provides higher security and reduces the risk of identity theft and fraudulent transactions. Non-contact biometric factor verification and digital verification can perform identity authentication without exposing the user's sensitive information, thereby protecting the user's privacy. This privacy protection measure enhances the user's trust in the transaction platform and promotes the user's acceptance and participation in real-name verification.

[0065] In the embodiment of the present invention, the authenticity and validity of the user's identity information are confirmed by verifying the user's ID card and mobile phone number. The ID card verification is specifically performed by scanning the ID card or manually entering the ID card information to ensure that the ID card information provided by the user is consistent with the real information. The mobile phone number verification is specifically performed by sending a verification code or making a call to verify whether the user's mobile phone number is valid. Different verification methods are adopted according to different user payment method data. If the user selects the first payment method, non-contact biometric factor verification is performed, such as face recognition, fingerprint recognition, etc. If the user selects the second payment method, digital verification is performed, such as password verification, digital signature verification, etc. Double authentication is performed in combination with the user's general verification data and the user's characteristic verification data to improve the reliability and security of identity authentication. If the user passes the general verification and characteristic verification, the system will generate user identity authentication data to confirm that the user's identity information has been strictly verified.

[0066] Preferably, when confirming that the user payment method data is the user's first payment method data, performing contactless biometric factor verification on the user includes:

[0067] When it is confirmed that the user payment method data is the user's first payment method data, facial recognition of the user is performed based on the camera module of the smart terminal to obtain user facial recognition data;

[0068] Extracting facial feature points from the user's facial recognition data to obtain the user's facial feature points, wherein the user's facial feature points include facial features and facial contours;

[0069] Based on the user's general verification data, facial feature comparison is performed on the user's facial feature points to obtain the user's first feature verification data.

[0070] The present invention confirms the identity of a user by verifying his or her facial features. Compared with traditional password or ID card verification methods, facial recognition has higher security because facial features are unique and difficult to forge. Contactless biometric factor verification does not require the user to provide additional information or perform complex operations. The verification can be completed by scanning the user's face through a camera. This convenience improves the user's transaction experience and reduces the trouble and time consumption of the verification process. Facial recognition technology can effectively prevent fraud and impersonation because facial features are unique and not easily forged or used. This verification method can improve the security of transactions and protect users from the threat of fraud and identity theft. Facial recognition usually only extracts and compares facial feature points, and does not store or transmit the user's real facial image. This privacy protection measure can increase the user's trust in biometric factor verification and reduce concerns about personal privacy.

[0071] In an embodiment of the present invention, facial recognition of the user is performed through a camera module based on a smart terminal to obtain facial image data of the user. The smart terminal should have a high-resolution camera that can capture clear facial images of the user. The user's facial recognition data is processed to extract facial feature points. Facial feature points include facial feature points (such as eyes, nose, mouth, etc.) and facial contours (such as face shape, face edges, etc.). Based on the user's general verification data, the extracted facial feature points are compared with the facial features registered by the user in advance. The comparison algorithm specifically uses face recognition technology, such as a face recognition algorithm based on deep learning, to ensure accuracy and reliability. When the extracted facial feature points match the facial features registered by the user to a certain threshold, it is considered that the verification is passed, and the user's first feature verification data is generated. The user's first feature verification data specifically includes information such as the time and place of the verification, which is used in the subsequent identity authentication process.

[0072] Preferably, performing facial feature comparison on the user's facial feature points based on the user's general verification data includes:

[0073] Obtain identity card verification data based on user general verification data;

[0074] Performing ID card facial recognition on the ID card verification data to generate ID card facial recognition data;

[0075] Extract facial feature points from ID card facial recognition data to obtain facial feature points of the user's ID card;

[0076] Using the face recognition algorithm, the feature similarity calculation is performed on the facial feature points of the user ID card and the facial feature points of the user to obtain the user's facial feature similarity;

[0077] The contactless biometric factor verification is performed based on the similarity of the user's facial features to generate the user's first characteristic verification data.

[0078] The present invention can obtain the facial feature point data of the user's ID card by obtaining the user's ID card verification data, performing ID card facial recognition and extracting facial feature points. The feature similarity between the facial feature points of the user's ID card and the user's real-time facial feature points is calculated using a face recognition algorithm, thereby achieving accurate verification of the user's identity. The contactless biometric factor verification combines the comparison of the user's real-time facial features and the ID card facial features, making the identity authentication more reliable and safe. Through feature similarity calculation, it can be determined whether the user's facial features match the facial features on his ID card, thereby avoiding the risk of fraud and impersonation. The process of facial feature comparison based on the user's general verification data is automated, without the need for the user to perform additional operations or provide additional information. The user only needs to perform ID card verification and facial scanning once to complete the verification, thereby improving the user's transaction experience and convenience. Facial feature comparison usually only involves the extraction and calculation of facial feature points, and does not store or transmit the user's facial image. This privacy protection measure can increase the user's trust in biometric factor verification while protecting the user's personal privacy.

[0079] In an embodiment of the present invention, based on the user's general verification data, the user's ID card information, including the ID card number and the ID card photo, is obtained. The ID card photo is used for facial recognition to extract the facial image data on the ID card. Specifically, image processing and computer vision technology are used to detect and crop the ID card photo to ensure that a clear facial image is extracted. The ID card facial recognition data is processed to extract the facial feature points on the ID card. The facial feature point extraction process is similar to the facial feature point extraction when the user is waiting to recycle gold, but this time it is aimed at the facial feature points on the ID card. The feature similarity of the extracted user ID card facial feature points and the user facial feature points collected by the smart terminal is calculated. Specifically, a face recognition algorithm is used to calculate the similarity between the two groups of facial feature points, and commonly used ones include deep learning-based face recognition algorithms such as FaceNet, OpenFace, etc. Verification is performed based on the calculated user facial feature similarity. When the facial feature similarity reaches a preset threshold, it is considered that the verification is passed, and the user's first feature verification data is generated.

[0080] Preferably, when confirming that the user payment method data is the user's second payment method data, digitally verifying the user includes:

[0081] When it is confirmed that the user payment method data is the user's second payment method data, the user's digital wallet code is identified based on the smart terminal to generate the user's digital wallet code;

[0082] Encode and authenticate the user's digital wallet code to generate the user's second characteristic verification data.

[0083] The present invention can ensure that the payment method data provided by the user is accurate by identifying the user's digital wallet code. This digital verification can prevent the user from providing erroneous or forged payment method information, and improve the accuracy and reliability of the transaction. Digital verification does not require the user to provide additional identity information or perform complex operations. The verification can be completed by simply identifying the user's digital wallet code through an intelligent terminal. This convenience improves the user's transaction experience and reduces the tediousness and time consumption of the verification process. The digital wallet code is an encrypted and secure payment method. The security of the transaction can be further guaranteed by encoding and authenticating it. This verification method can prevent others from impersonating the user's payment method data and reduce the occurrence of payment risks and fraud. Digital verification usually only involves the user's digital wallet code, and does not involve the user's personal sensitive information. This privacy protection measure increases the user's trust in digital verification while protecting the user's personal privacy.

[0084] In an embodiment of the present invention, when it is confirmed that the payment method selected by the user is a digital wallet, the corresponding function module is enabled on the smart terminal, and the user's digital wallet code is identified through a camera or a code scanning function. Specifically, image processing technology or code scanning recognition technology is used to capture the user's digital wallet code. If it is a QR code, the existing QR code scanning library is used to scan and identify it; if it is a digital code, the digital wallet code is specifically identified and extracted by image processing and recognition algorithms. After obtaining the digital wallet code input by the user, it is subjected to code identity verification, which involves verifying the validity and legitimacy of the user's digital wallet code, such as checking whether the digital wallet code meets specific format requirements and whether it matches the registered user information. Specifically, the digital wallet code is decrypted using an encryption algorithm, and then compared with the user's registration information or bound payment information. When the digital wallet code passes the code identity verification, the user's second characteristic verification data can be generated. These verification data include information such as the validity and consistency of the user's digital wallet code to confirm the user's identity and payment method.

[0085] Preferably, performing coded identity authentication on the user's digital wallet code includes:

[0086] Perform digital signature authentication on the user's digital wallet code and generate digital signature authentication data;

[0087] Perform key pair matching on the user's digital wallet code to generate key pair matching data;

[0088] Match the wallet address of the user's digital wallet code to generate digital wallet address matching data;

[0089] The user is digitally verified based on the digital signature authentication data, key pair matching data and digital wallet address matching data to generate the user's second characteristic verification data.

[0090] The present invention can verify the authenticity and integrity of the code by performing digital signature authentication on the user's digital wallet code. Digital signature uses the user's private key to encrypt the code, and uses the public key to decrypt and verify during verification. Through digital signature authentication, it can be confirmed that the code is generated by the user who has the corresponding private key, thereby ensuring the identity authenticity and data integrity of the code. The user's digital wallet code is matched with a key pair to ensure that the code matches the user's key pair. The key pair consists of a public key and a private key, the public key is used for encryption and verification, and the private key is used for decryption and signing. Through key pair matching, it can be confirmed that the code is consistent with the user's key pair, and the identity authenticity of the code is further confirmed. The user's digital wallet code is matched with a wallet address to verify whether the code is consistent with the user's digital wallet address. The digital wallet address is the user's unique identifier in the digital wallet. Through wallet address matching, it can be confirmed that the code is consistent with the user's digital wallet address, ensuring the identity authenticity of the code. According to the digital signature authentication data, the key pair matching data and the digital wallet address matching data, the user is comprehensively verified to generate the user's second characteristic verification data. The comprehensive analysis of these verification data can further confirm the user's identity authenticity and the validity of the digital wallet code.

[0091] In an embodiment of the present invention, the integrity and authenticity of the code are ensured by performing digital signature authentication on the user's digital wallet code, such as email signature authentication, software release signature authentication, electronic contract signing, and blockchain transaction verification. In the digital signature authentication process, the digital wallet code is signed using a digital certificate and a public key encryption algorithm. This usually involves using a digital certificate issued by a digital certificate authority and the corresponding public key. The user's digital wallet code is matched with a key pair to verify whether it matches the pre-stored key pair. This involves using the public key and private key in the public key encryption algorithm to ensure that the digital wallet code provided by the user matches the pre-stored key pair, thereby ensuring its legitimacy. The user's digital wallet code is matched with a wallet address to ensure that it matches the wallet address that the user has registered or bound, which involves comparing the digital wallet code provided by the user with the wallet address in the database to ensure its consistency and legitimacy. According to the digital signature authentication data, the key pair matching data, and the digital wallet address matching data, the user is digitally verified to generate the user's second characteristic verification data. These verification data specifically include digital signature verification results, key pair matching results, wallet address matching results, etc., which are used to confirm the legitimacy and authenticity of the user's identity and payment method.

[0092] Preferably, step S5 comprises the following steps:

[0093] Step S51: Determine whether the user identity authentication data is passed. If the user identity authentication is not passed, the transaction failure is processed based on the smart terminal;

[0094] Step S52: After the user identity verification is passed, the gold to be recycled is smelted, and the quality of the smelted gold to be recycled is secondary tested, and the final price of gold recycling is generated and displayed on the smart terminal page, generating a gold recycling final price interface;

[0095] Step S53: User confirmation is performed according to the gold recycling final price interface. After the user confirms, the transaction backend pays the gold recycling fee to the user to complete the gold recycling transaction. The user confirmation on the gold recycling final price interface specifically includes:

[0096] Collecting the user's first touch data based on the first touch area of ​​the gold recycling final price interface;

[0097] Based on the second touch area of ​​the gold recycling final price interface, the user's second touch data is collected.

[0098] The area that the user touches first is the area for agreeing to the transaction, and the area that the user touches second is the area for canceling the transaction.

[0099] The present invention can ensure that transactions are limited to verified and authentic users and that the quality of the recovered gold meets the requirements by verifying the identity of the user and performing gold quality inspection. By displaying the final price of gold recovery on the intelligent terminal and providing a user confirmation and judgment interface, the user can intuitively understand the recovery price and confirm the transaction through a simple touch operation, thereby improving the transaction convenience and experience of the user. Through the user's confirmation and judgment, it can be ensured that the user voluntarily conducts the transaction, avoid the occurrence of misoperation or unauthorized transactions, and improve the reliability and accuracy of the transaction. By paying the gold recovery fee to the user, the system provides real-time feedback on the transaction results, allowing the user to obtain the final result of the transaction and enhance the user's trust and satisfaction with the transaction.

[0100] As an example of the present invention, refer to Figure 3 As shown, in this example, step S5 includes:

[0101] Step S51: Determine whether the user identity authentication data is passed. If the user identity authentication is not passed, the transaction failure is processed based on the smart terminal;

[0102] In an embodiment of the present invention, user identity verification data is obtained from the previous steps, including identity card verification data, facial recognition data, digital wallet code verification data, etc. The obtained user identity verification data is analyzed and compared to determine whether it meets the preset authentication standards and conditions. If the identity verification data provided by the user meets the authentication standards, the identity verification is considered to be successful; otherwise, the identity verification is considered to be unsuccessful. When the user identity verification fails, the transaction is considered to have failed. At this time, corresponding processing needs to be performed on the smart terminal. Specifically, a prompt message of transaction failure is displayed on the interface of the smart terminal to inform the user of the reason why the identity verification failed, and provide relevant guidance and solutions. At the same time, the user can be provided with the option of re-authenticating so that the user can correct the identity verification data or take other measures to solve the identity verification problem.

[0103] Step S52: After the user identity verification is passed, the gold to be recycled is smelted, and the quality of the smelted gold to be recycled is secondary tested, and the final price of gold recycling is generated and displayed on the smart terminal page, generating a gold recycling final price interface;

[0104] In an embodiment of the present invention, after confirming that the user identity authentication data has passed, the subsequent gold recovery process can be carried out. The gold to be recovered is placed in a smelting device for smelting, and the gold is heated to its melting point to convert it into a liquid state. The smelting process needs to be carried out in a professional gold recovery device or smelting studio to ensure operational safety and gold quality. The smelted gold is subjected to a secondary quality test to ensure that the gold quality meets the requirements. Specifically, advanced metal analysis instruments or chemical analysis methods are used to perform component analysis, purity testing, etc. on the gold to ensure that it meets quality standards. Based on the gold quality data after smelting and quality testing, combined with the current gold market price and other relevant factors, the final gold recovery price is calculated. The calculated final price of gold recovery is displayed on the smart terminal page, and a gold recovery final price interface is generated for the user to view and confirm.

[0105] Step S53: User confirmation is performed according to the gold recycling final price interface. After the user confirms, the transaction backend pays the gold recycling fee to the user to complete the gold recycling transaction. The user confirmation on the gold recycling final price interface specifically includes:

[0106] Collecting the user's first touch data based on the first touch area of ​​the gold recycling final price interface;

[0107] Based on the second touch area of ​​the gold recycling final price interface, the user's second touch data is collected.

[0108] The area that the user touches first is the area for agreeing to the transaction, and the area that the user touches second is the area for canceling the transaction.

[0109] In an embodiment of the present invention, an interactive interface is designed to mark an area of ​​"agree to transaction" on the interface, and this area is the area touched by the user with a finger. When the user clicks on this area, the smart terminal collects the user's first touch data. Another area is designed to mark an area of ​​"cancel transaction" on the interface, and this area is the area touched by the user with a finger. When the user clicks on this area, the smart terminal collects the user's second touch data. After the smart terminal collects the user's touch data, the user's transaction intention is judged according to the different touch positions. If the user touches the "agree to transaction" area, it is deemed that the user confirms the transaction; if the user touches the "cancel transaction" area, it is deemed that the user cancels the transaction.

[0110] Preferably, step S53 includes the following steps:

[0111] Step S531: based on the preset time interval, the user touch area is judged according to the gold recycling final price interface. When the user times out and the user touch area is judged as the transaction approval area, step S531 is repeated; when the user touch area is judged as the transaction cancellation area, the transaction failure processing is performed based on the user's second touch data;

[0112] Step S532: when the user is within the preset time interval and the area touched by the user is determined to be the area of ​​agreed transaction, the transaction information of the user is recorded based on the first touch data of the user, and the user transaction order information data is generated, wherein the user transaction order information data includes the transaction amount, transaction time and transaction unique identification number;

[0113] Step S533: Use blockchain technology to persistently store user transaction order information data based on the transaction background, generate transaction order storage data, and use it to pay the gold recovery amount to the user to complete the gold recovery transaction.

[0114] The present invention can prevent transaction problems caused by user overtime operation or misoperation by setting preset time intervals and touch area discrimination, and ensure the accuracy and reliability of transactions. By recording user transaction information and generating transaction order information data, the system can provide transaction vouchers and facilitate subsequent data management and analysis, thereby improving the traceability and management efficiency of transactions. Using blockchain technology to store transaction orders and pay for gold recovery can ensure the security, immutability and traceability of transaction data, and enhance the reliability of transactions and the trust of users.

[0115] As an example of the present invention, refer to Figure 4 As shown, in this example, step S53 includes:

[0116] Step S531: based on the preset time interval, the user touch area is judged according to the gold recycling final price interface. When the user times out and the user touch area is judged as the transaction approval area, step S531 is repeated; when the user touch area is judged as the transaction cancellation area, the transaction failure processing is performed based on the user's second touch data;

[0117] In an embodiment of the present invention, a preset time interval is set to determine whether the user has timed out and has not made a selection. While waiting for the user to touch, the intelligent terminal records the user's touch and counts the time. When the user's touch time exceeds the preset time interval, and the area touched by the user is determined to be the "agree to transaction" area, step S531 is repeated. If the area touched by the user is determined to be the "cancel transaction" area, step S532 is executed. When the area touched by the user is determined to be the "cancel transaction" area, the transaction failure processing is performed based on the user's second touch data, and the corresponding prompt information is displayed on the intelligent terminal to inform the user that the transaction has been canceled.

[0118] Step S532: when the user is within the preset time interval and the area touched by the user is determined to be the area of ​​agreed transaction, the transaction information of the user is recorded based on the first touch data of the user, and the user transaction order information data is generated, wherein the user transaction order information data includes the transaction amount, transaction time and transaction unique identification number;

[0119] In an embodiment of the present invention, the user is waited for to touch the interface within a preset time interval. The user's touch area is judged to confirm whether it is in the "agree to transaction" area. When the user touches within the preset time and the touch area is judged as "agree to transaction", the relevant transaction information is recorded. User transaction order information usually includes the following: Transaction amount: The transaction amount determined according to the final price of gold recycling. Transaction time: Record the specific time when the transaction occurs. Transaction unique identification number: Used to uniquely identify the transaction, usually a unique identifier generated by the system. The recorded transaction information is integrated into user transaction order information data. These data can be stored in the system for subsequent processing and tracking of transactions.

[0120] Step S533: Use blockchain technology to persistently store user transaction order information data based on the transaction background, generate transaction order storage data, and use it to pay the gold recovery amount to the user to complete the gold recovery transaction.

[0121] In an embodiment of the present invention, the user transaction order information data is persistently stored using blockchain technology. Blockchain provides decentralized, tamper-proof, safe and reliable characteristics to ensure the security and transparency of transaction data. The transaction backend is responsible for sending the user transaction order information data to the blockchain network, which is specifically achieved by calling a smart contract. The smart contract is responsible for creating transaction records on the blockchain and storing the user's transaction information. After the transaction order information data is stored on the blockchain, the transaction order storage data is obtained. These data are tamper-proof on the blockchain and can be accessed by all participants, ensuring the transparency and traceability of the transaction. When the transaction order storage data has been generated on the blockchain, the transaction backend can pay the gold recovery fee to the user based on the transaction order information. This usually involves sending a corresponding amount of gold or equivalent funds to the digital wallet address specified by the user.

[0122] The beneficial effect of the present invention is that through the quality detection and price estimation of the intelligent terminal, the user can clearly understand the quality and expected price of the gold to be recycled. The price prediction based on machine learning can more accurately estimate the gold recovery price, improve the fairness and accuracy of the transaction, and meet the user's demand for price information. The real-name verification of the user's payment method data improves the security and reliability of the transaction and ensures the authenticity and legitimacy of the user's identity during the transaction. The secondary detection of gold quality and the final price confirmation guarantee the quality and accuracy of the transaction, provide users with reliable gold recovery services, and enhance the user's sense of trust and satisfaction. The timeliness and accuracy of the transaction backend to pay the gold recovery amount to the user improves the efficiency and convenience of the transaction and promotes the development and prosperity of the gold recovery market. Therefore, the present invention improves the efficiency and security of the transaction through real-time price prediction, multiple payment methods, identity authentication and secondary quality detection.
