[0090] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0091] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0092] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0093] The main solution of this application embodiment is as follows: Obtain the bidder's current bidding information and historical bidding information; perform anti-collusion behavior identification on the current bidding information, historical bidding information, and the bidder's network behavior based on a large language model, and obtain the anti-collusion behavior identification result; and issue a collusion behavior warning based on the anti-collusion behavior identification result. Since this application uses a large language model to identify anti-collusion behavior based on the current bidding information, historical bidding information, and the bidder's network behavior, and issues a collusion behavior warning based on the anti-collusion behavior identification result, compared to existing methods of manually reviewing bid-rigging processes, the above method of this application can comprehensively and accurately identify collusion behavior using intelligent means.

[0094] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or AI browser capable of performing the above functions. The following description uses the AI ​​browser as an example to illustrate this embodiment and the subsequent embodiments.

[0095] Based on this, embodiments of this application provide a method for identifying tag-scratching behavior, referring to... Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the tag-scraping behavior identification method of this application.

[0096] In this embodiment, the method for identifying trolling behavior includes the following steps:

[0097] Step S10: Obtain the bidder's current bidding information and historical bidding information;

[0098] It should be noted that the bidder can be a legal person, other organization, or individual that responds to a tender and participates in the competition with the aim of winning the bid. The bidder's current bidding information may include the bidder's basic information and bid documents. The basic information may include the bidder's name, contact information, company name, registered address, and legal representative. The bid documents may be responsive documents prepared by the bidder in accordance with the requirements of the tender documents, and may consist of commercial documents, technical documents, price quotations, and other parts. The historical bidding information may include the bidder's historical bid documents in previous bidding processes, performance information in bidding projects, and information on whether there has been any abnormal behavior such as bid rigging.

[0099] Step S20: Based on the large language model, identify anti-collusion behavior of the current bidding information, the historical bidding information, and the network behavior of the bidder to obtain the anti-collusion behavior identification result;

[0100] It should be noted that the Large Language Model (LLM) is a deep learning model trained using a large amount of text data. It can generate natural language text or understand the meaning of language text. The LLM can handle various natural language tasks, such as text classification, question answering, and dialogue. The anti-collusion behavior identification based on the LLM for the current bidding information, historical bidding information, and the bidder's online behavior can be achieved by using the LLM to analyze user behavior data (including the current bidding information, historical bidding information, and the bidder's online behavior) in real time to identify potential collusion behaviors. Multimodal fusion analysis, combining text, images, and online behavior data, improves the accuracy of the analysis and detection. The bidder's online behavior may include information collected by the AI ​​browser, such as the CPU serial number, memory serial number, hard disk serial number, MAC address, IP address, and operating system version of the terminal used by the bidder.

[0101] In practice, when applying for bidding, bidders must first register and log in to the bidding platform. Registration requires uploading basic information, including facial recognition data. Subsequent bidding processes, such as uploading bid documents, must be performed by the registered bidder. After successful registration and login, the bidding platform will instruct the bidder to install a dedicated AI browser. Bidders can only participate in the bidding process by accessing the bidding system through this installed AI browser. The AI ​​browser can obtain information about the bidder's currently used terminal, including CPU serial number, memory serial number, hard drive serial number, MAC address, IP address, and operating system version.

[0102] Furthermore, in order to improve the prediction accuracy of the large language model, after step S20, the method further includes: determining sample data based on the anti-collusion behavior identification result, the current bidding information, the historical bidding information, and the bidder's network behavior;

[0103] The large language model is iteratively optimized based on the sample data to obtain a new large language model, and the new large language model is used to replace the old large language model.

[0104] It should be noted that, in this embodiment, after predicting the anti-collusion behavior identification result through the large language model, it can be further confirmed by relevant personnel. After obtaining the confirmation result from relevant personnel, the input and output data (anti-collusion behavior identification result, current bidding information, historical bidding information, and bidders' network behavior) can be used as sample data for iterative optimization of the large language model. It can also receive suggestions from various bidders based on their operation and use of the AI ​​browser, and further optimize relevant parameters and pre-set judgment rules in the large language model based on these suggestions.

[0105] Step S30: Issue a warning about cross-selling behavior based on the anti-cross-selling behavior identification results.

[0106] It should be noted that the anti-collusion behavior identification result can be used to issue an early warning based on a preset early warning strategy when the anti-collusion behavior identification result indicates that collusion behavior may exist. The preset early warning strategy is a pre-set early warning method, which may include strategies such as automatically sending relevant warning information to relevant personnel, reminding them to pay attention to preventing collusion behavior, canceling the bidder's bidding qualification, and adding the bidder to the blacklist.

[0107] Furthermore, in order to ensure the data security of bidders and prevent data leakage, after step S20, the method further includes: when the anti-collusion behavior identification result is that there is no collusion behavior, obtaining a preset encryption algorithm;

[0108] The current bidding information is encrypted based on the preset encryption algorithm to obtain encrypted bidding information;

[0109] The encrypted bidding information is sent to the preset bidding terminal.

[0110] It should be noted that the preset encryption algorithm can be a national cryptographic algorithm, including SM1, SM2, SM3, SM4, etc. The preset bidding terminal can be a bidding system.

[0111] In practice, all data exchanges between the AI ​​browser and the bidding system are encrypted using a pre-set encryption algorithm to prevent interception and ensure the security of data transmission and storage. Furthermore, both the AI ​​browser and the bidding system undergo regular security checks and vulnerability patching to guarantee their security.

[0112] This embodiment obtains the bidder's current and historical bidding information; it uses a large language model to identify anti-collusion behavior based on the current bidding information, historical bidding information, and the bidder's online behavior, obtaining anti-collusion behavior identification results; and it issues a collusion behavior warning based on the anti-collusion behavior identification results. Because this embodiment uses a large language model to identify anti-collusion behavior based on the current bidding information, historical bidding information, and the bidder's online behavior, and issues a collusion behavior warning based on the anti-collusion behavior identification results, compared to existing methods of manually reviewing bids for collusion, this embodiment can comprehensively and accurately identify collusion behavior using intelligent means.

[0113] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in Embodiment 1 above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating a second embodiment of the tag-scraping behavior recognition method of this application. In step S20, the large language model includes a general large language model and a preset tag-scraping behavior recognition model. Step S20 also includes the following steps:

[0114] Step S201: Based on the preset bid-rigging behavior identification model, perform anti-bid-rigging behavior identification on the current bidding information and the bidder's network behavior to obtain the first anti-bid-rigging behavior identification result;

[0115] It should be noted that the preset bid-rigging behavior identification model can be a large language model trained on sample data for identifying anti-bid-rigging behavior in the current bidding information and the bidder's network behavior. The sample data may include pre-collected information such as the current bidding information, historical bidding information, the bidder's network behavior, and indicators of whether bid-rigging behavior exists. The step of identifying anti-bid-rigging behavior based on the preset bid-rigging behavior identification model to obtain a first anti-bid-rigging behavior identification result can be achieved by inputting the current bidding information and the bidder's network behavior into the preset bid-rigging behavior identification model and obtaining the first anti-bid-rigging behavior identification result output by the preset bid-rigging behavior identification model.

[0116] Furthermore, in order to improve the efficiency of identifying bid-rigging behavior, step S201 may include: determining the bid document information and the bidder's basic information based on the current bidding information;

[0117] Based on the preset bid-rigging behavior recognition model, information analysis is performed on the basic information and the bid document information to obtain information recognition results;

[0118] The bidder's network behavior is input into the preset anti-collusion behavior identification model to identify anti-collusion behavior and obtain the network behavior identification result.

[0119] The first anti-scraping behavior identification result is determined based on the network behavior identification result and the information identification result.

[0120] It should be noted that the tender document information can be technical, pricing, and other responsive documents uploaded by the bidder during the bidding process. The basic information may include the bidder's company name, registered address, legal representative, etc. Based on the preset bid-rigging behavior identification model, information analysis is performed on the basic information and the tender document information to obtain the information identification result. This can be based on bidder information analysis and tender document content analysis using the preset bid-rigging behavior identification model. Specifically, bidder information analysis includes extracting the bidder's basic information and analyzing whether there are any related relationships. If there are related relationships among multiple bidders, it is determined that bid-rigging behavior may exist. Tender document content analysis includes extracting key content of the tender documents (such as technical solutions, pricing, commitments, etc.), analyzing similarity, and determining whether there is a risk of bid-rigging based on the similarity and a preset similarity threshold. The process of inputting the bidder's network behavior into the preset bid-rigging behavior identification model for anti-bid-rigging behavior identification can obtain network behavior identification results. This can include using the preset bid-rigging behavior identification model to monitor the upload time, IP address, and network of the tender documents, analyzing whether multiple tender documents originate from the same IP address or network within the same time period, and obtaining network behavior identification results. The determination of the first anti-collusion behavior identification result based on the network behavior identification result and the information identification result can be based on the collusion risk information identified in the network behavior identification result and the information identification result and a pre-set judgment rule. The pre-set judgment rule can be a pre-set condition under which a collusion risk is determined and an early warning is required. For example, if two bid documents are uploaded through the same IP address within a preset time interval, it is determined that collusion behavior may exist.

[0121] Furthermore, in order to accurately identify whether bidders are engaging in bid rigging, the preset bid rigging behavior identification model performs information analysis on the basic information and the bid document information to obtain the information identification result, including the following steps:

[0122] Based on the preset bid-rigging behavior identification model, the basic information is analyzed to determine the relationship between the bidders.

[0123] The bid document information is feature extracted according to the preset bid-rigging behavior recognition model, and the bid document similarity between bid documents is determined according to the feature extraction results;

[0124] The information identification result is determined based on the aforementioned relationship and the similarity of the tender documents.

[0125] It should be noted that the step of analyzing the bidder association information based on the preset bid-rigging behavior identification model to determine the relationships between bidders can be achieved by using the preset bid-rigging behavior identification model to determine whether there are relationships between each bidder and its corresponding company based on the basic information, such as whether there are business dealings, whether they are the same legal entity, whether their registered addresses are the same, or whether there is overlap in investor information. The step of extracting features from the bid document information according to the preset bid-rigging behavior identification model and determining the bid document similarity based on the feature extraction results can be achieved by extracting features from each bidder's bid documents, calculating the similarity of each bid document based on the feature extraction results, including the similarity of technical solutions, quotations, commitments, etc., and then calculating the final bid document similarity based on the pre-set weights corresponding to the technical solutions, quotations, commitments, etc. The step of determining the information identification result based on the association and the bid document similarity can be achieved by the preset bid-rigging behavior identification model predicting the information identification result based on the association and the bid document similarity. Alternatively, a pre-set bid-rigging behavior identification model can be used to output only the association relationship and the similarity of the bid documents, and the information identification result can be determined based on the association relationship and the similarity of the bid documents using pre-set judgment rules. The pre-set judgment rules may include determining that bid-rigging exists if there is an association relationship between the bidders; or determining that bid-rigging exists if the similarity of the bid documents is greater than a preset similarity threshold.

[0126] Furthermore, in order to accurately identify whether bidders are engaging in bid rigging, the step of inputting the bidders' online behavior into the preset bid rigging behavior identification model for anti-bid rigging behavior identification and obtaining the network behavior identification result includes:

[0127] Based on the preset bid-rigging behavior identification model, the network behavior features of the bidder are extracted to obtain network behavior features;

[0128] Based on the network behavior characteristics, target network behaviors that meet preset abnormal conditions are determined.

[0129] The network behavior identification result is determined based on the target network behavior.

[0130] It should be noted that the feature extraction of the bidder's network behavior can yield network behavior features such as the attributes of the uploaded documents, the path of the bid documents, the directory of the bid documents, the upload time of the bid documents, the IP address, and the network connected. The preset anomaly conditions can include identical or similar paths for bid documents, identical or similar directories for bid documents, identical or similar names for bid documents, and identical IP addresses or networks used to upload bid documents. Determining target network behaviors that meet the preset anomaly conditions based on these network behavior features can involve determining whether each bidder's network behavior meets the aforementioned preset anomaly conditions. If it does, the network behaviors that meet the preset anomaly conditions and the corresponding bidders are identified, and a network behavior identification result is generated.

[0131] Step S202: Input the historical bidding information into the general large language model to obtain the second anti-collusion behavior identification result output by the general large language model;

[0132] It should be noted that the step of inputting the historical bidding information into the general large language model to obtain the second anti-collusion behavior identification result output by the general large language model can be achieved by using the general large language model to analyze the bidding data and behavior of each bidder in the historical bidding information, to obtain the bidder's performance in different projects, to identify the bidder's abnormal behavior, and to obtain the second anti-collusion behavior identification result.

[0133] Step S203: Determine the anti-scraping behavior identification result based on the first anti-scraping behavior identification result and the second anti-scraping behavior identification result.

[0134] It should be noted that, when determining the anti-collusion behavior identification result based on the first and second anti-collusion behavior identification results, the anti-collusion behavior identification result indicates that the bidder has a risk of collusion. Conversely, if both the first and second anti-collusion behavior identification results indicate no risk of collusion, the anti-collusion behavior identification result indicates that the bidder does not have a risk of collusion.

[0135] This embodiment uses the preset bid-rigging behavior identification model to identify anti-bid-rigging behaviors in the current bidding information and the bidder's network behavior, obtaining a first anti-bid-rigging behavior identification result. The historical bidding information is then input into the general large language model to obtain a second anti-bid-rigging behavior identification result output by the general large language model. The final anti-bid-rigging behavior identification result is determined based on the first and second results. This embodiment combines the general large language model and the preset bid-rigging behavior identification model to identify bidders' bid-rigging behavior, effectively preventing and detecting such behavior. This significantly improves the accuracy of identifying bid-rigging and collusion, reduces the probability of false positives and false negatives, and maintains a fair and competitive market environment.

[0136] Based on the above embodiments of this application, in the third embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 , Figure 3 This is a flowchart illustrating an embodiment of the tag-scratching behavior identification method of this application. Before step S10, the method further includes the following steps:

[0137] Step S001: Collect the bidder's facial information;

[0138] It should be noted that in this embodiment, when registering on the bidding platform, bidders need to upload their basic information, including facial information. During subsequent bidding processes, such as uploading bid documents, the registered bidder must perform the operations themselves. When the bidder performs bidding operations using the AI ​​browser, the AI ​​browser will collect the bidder's facial information in real time.

[0139] Step S002: Determine whether the bidder is a legitimate user based on the facial information;

[0140] It should be noted that the step of determining whether the bidder is a legitimate user based on the facial information can be achieved by comparing the facial information with the facial information of the bidder when registering on the bidding platform. If the comparison is successful, the bidder is determined to be a legitimate user.

[0141] Furthermore, in order to reduce the risk of collusion, step S002 may include: determining the target facial features based on the facial information;

[0142] The target facial features are matched against the user information in the bidding application to obtain the matching result;

[0143] The matching results will be used to determine whether the bidder is a legitimate user.

[0144] It should be noted that determining the target facial features based on the facial information can be achieved by using a facial feature extraction algorithm to extract facial features from the facial information. The facial feature extraction algorithm may include DeepFace, Viola-Jones, etc. The user information for applying for bidding may include the facial feature information of all bidders applying for bidding. After determining other basic information of the bidders, the facial feature information of the bidders during registration can also be directly obtained based on the bidders' basic information. The target facial features are then matched with the facial feature information of the bidders during registration to obtain a matching result. If the match is successful, the bidder is determined to be a legitimate user; if the match is unsuccessful, the bidder is determined to be an illegitimate user, the bidder's bidding operations are restricted, and a warning message is issued to the bidding platform or relevant personnel.

[0145] Step S003: When the bidder is not a legitimate user, send a preset warning message.

[0146] It should be noted that the bidder in this embodiment must be the same as the bidder registered on the bidding platform. If they are not the same, the bidder is deemed not to meet the bidding conditions, a warning message is sent to the relevant personnel, and their bidding operations are restricted.

[0147] In specific implementation, it can be referred to Figure 4 , Figure 4 This diagram illustrates the AI ​​browser module provided in Embodiment 3 of the tag-scraping behavior identification method of this application. The AI ​​browser in this embodiment includes a computer information module, a face recognition module, a data acquisition module, an anti-tag-scraping analysis module, an early warning module, a data encryption module, a backend service module, and a user feedback module. The AI ​​browser's interface is responsible for user interface display and user interaction.

[0148] The computer information module can obtain relevant information about the current computer device, including CPU serial number, memory serial number, hard disk serial number, MAC address, IP address, operating system version, etc., providing basic data for the anti-spoofing analysis module.

[0149] Face recognition module: Integrates advanced facial recognition algorithms to ensure accurate face detection even in low-light and occluded conditions, and identifies the user through the facial recognition algorithm. The browser analyzes the captured facial information in real time to determine if the user is legitimate.

[0150] Data acquisition module: Collects user actions and uploaded document attributes during the bidding process, such as the path and directory of the bid documents, and the concentration of bidding time.

[0151] Anti-collusion analysis module: Utilizing AI algorithms (i.e., a general-purpose large language model) and pre-set collusion behavior models (i.e., pre-set collusion behavior recognition models), it analyzes user behavior data in real time to identify potential collusion behaviors. Through multi-modal fusion, it combines multiple data sources such as text, images, and network behavior to perform multi-modal fusion analysis, improving the accuracy of analysis and detection. It uses deep learning techniques (such as Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs)) to train the model, identify complex collusion patterns, and combines expert knowledge and historical cases to formulate a series of rules to assist the model in decision analysis. This may include the following analyses: 1. Bidder basic information analysis: Extracting basic information of bidders (such as company name, registered address, legal representative, etc.) and analyzing whether there are any related relationships. 2. Bid document content analysis: Using natural language processing technology to extract key content of bid documents (such as technical solutions, quotations, commitments, etc.) and analyzing similarity. 3. Historical bidding record analysis: Combining historical bidding data to analyze the performance of bidders in different projects and identify abnormal behavior. 4. Network Behavior Analysis: Monitor the upload time, IP address, MAC address, CPU serial number, and network information of the tender documents to analyze whether there are multiple tender documents from the same IP address or network within the same time period.

[0152] Early warning module: Based on the anti-bid-collusion analysis results, it automatically sends early warnings to relevant personnel, reminding them to be vigilant against bid-collusion. This includes developing a real-time monitoring engine to immediately analyze and evaluate received bid documents. Once potential bid-collusion is detected, it immediately issues a warning to the bidding party and provides a detailed report.

[0153] Data encryption module: Encrypts data transmitted between the AI ​​browser and the bidding system to prevent interception and ensure the security of data transmission and storage. Regular security checks and vulnerability patching are also performed to ensure the security of the AI ​​browser.

[0154] Backend service module: Responsible for processing data analysis and early warning data, providing real-time monitoring and management functions, and dynamically adjusting the cross-selling behavior identification model and early warning strategy according to user behavior and environmental changes to ensure the effectiveness of anti-cross-selling.

[0155] User feedback module: Users can provide feedback on the operation of the AI ​​browser. Based on user feedback, relevant personnel will continuously optimize the AI ​​algorithm and parameter configuration to improve the AI ​​browser's intelligent analysis and decision-making capabilities.

[0156] This embodiment collects the bidder's facial information; determines whether the bidder is a legitimate user based on the facial information; and sends a preset warning message when the bidder is not a legitimate user. This embodiment reduces the probability of bid rigging by restricting bidders to be identical to those registered on the bidding platform and by collecting and comparing the bidder's facial information in real time.

[0157] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the tag-matching behavior identification method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.
