[0119] In some embodiments, it also includes:

[0120] The contract management module is used to automatically monitor the validity period of the electronic contract and remind the user of the expiration and renewal of the electronic contract by SMS or email before the electronic contract expires. The renewal matters include the contract renewal process; and to record the contract renewal history and contract changes for easy audit and inquiry.

[0121] Specifically, the contract management module works as follows:

[0122] When user information and electronic contracts are persistently stored by the database module, the validity period information of the contract will also be recorded in the database; the contract management module will run a scheduled task regularly (such as daily or weekly), which will query all expiring contract records in the database; the contract management module will compare the current date with the validity period in the contract record to determine which contracts are about to expire; for contracts that are about to expire, the contract management module will generate reminder information, which may include the contract expiration date, renewal process guidance, etc.; the contract management module will send contract expiration reminders to users through preset communication channels (such as SMS or email); the information of these communication channels is usually specified by the user when the user registers or signs the contract.

[0123] After receiving the reminder, the user can follow the instructions in the reminder to perform the corresponding renewal operation or contact the power supply company for consultation; the renewal matters provided by the contract management module include detailed renewal processes, and users can follow these processes, such as re-uploading necessary electronic materials, confirming new electricity demand, etc.; when the user completes the renewal operation, the contract management module will record the relevant information of the renewal in the database, including the renewal date, the contract terms after renewal, etc.

[0124] If the contract content changes during the renewal process, the contract management module will also record these changes, including the content of the change, the date of the change, etc. The contract management module provides an audit and query interface that allows authorized personnel (such as managers or auditors of power supply companies) to view the contract renewal history and changes for the purpose of auditing and supervision management.

[0125] The contract management module not only improves the automation level of contract management, but also ensures the continued validity and compliance of the contract. It also provides users with convenient renewal services and enhances the user experience.

[0126] In some embodiments, the business audit module includes:

[0127] An OCR recognition unit is used to automatically recognize text information in electronic materials submitted by users and convert it into an editable text format;

[0128] Database comparison interface, used to compare the text information in the electronic materials submitted by users with the official database to verify the authenticity and validity of the information;

[0129] The credit assessment module is used to assess the user's credit status during the review process to determine whether the user has credit risk;

[0130] The audit output unit is used to pass the audit if the text information in the electronic material is true and valid and the user's credit status is evaluated to be good, otherwise the audit is not passed;

[0131] The manual review unit is used to review the business application and electronic materials submitted by the user by a manual reviewer when the automatic review cannot be determined or there is doubt;

[0132] The audit record storage unit is used to store all records in the audit process.

[0133] Specifically, the business review module works as follows:

[0134] When users upload electronic materials (such as identity documents, business licenses, etc.) through the client, these materials will be sent to the server. The OCR (Optical Character Recognition) recognition unit will scan these electronic materials and automatically recognize the text information in the materials. The OCR recognition unit will convert the recognized text information into an editable text format for subsequent processing and comparison.

[0135] The database comparison interface extracts key information from the text output by the OCR recognition unit, such as name, ID number, company registration number, etc.; compares this key information with official databases (such as identity information databases, business registration information databases, etc.); verifies authenticity: verifies whether the information in the electronic materials submitted by the user is authentic and valid through the comparison results.

[0136] During the review process, the credit assessment module will obtain relevant information about the user and use this information to assess the user's credit status, which may include credit history, repayment record, credit score, etc. The assessment results are used to determine whether the user has credit risk, which is crucial in deciding whether to provide services.

[0137] The audit output unit makes an audit decision based on the OCR recognition results, database comparison results and credit assessment results. If the text information in the electronic material is true and valid and the user's credit status is assessed to be good, the audit is passed; otherwise, the audit is failed.

[0138] When the automatic review is uncertain or in doubt, the manual review unit intervenes and the manual reviewer conducts a detailed review of the business application and electronic materials submitted by the user to make a final review decision.

[0139] All records of the audit process, including OCR recognition results, database comparison results, credit assessment results, audit decisions, etc., will be stored in the audit record storage unit. The stored records can be used for future audits, inquiries and traceability to ensure the transparency and traceability of the audit process.

[0140] Through the above working principle, the business review module can efficiently and accurately review the business applications and electronic materials submitted by users, ensuring that power supply companies can provide services to qualified users while reducing business risks.

[0141] In some embodiments, the OCR recognition unit includes:

[0142] Preprocessing layers, used to convert raw images into a form that the network can process;

[0143] The feature extraction layer is used to extract feature sequences from the output data of the preprocessing layer;

[0144] The sequence modeling layer is used to convert the feature sequence extracted by the feature extraction layer into the probability distribution of the character sequence;

[0145] The decoding layer is used to convert the probability distribution of character sequences into the final text output.

[0146] Specifically, the Image Preprocessing Layer preprocesses the input image, including size normalization, grayscale, denoising, binarization, tilt correction, etc., to improve the accuracy of subsequent processing. It is the first layer of the model and directly receives the original image data.

[0147] The Feature Extraction Layer extracts features from the preprocessed image. These features are crucial for character recognition. They include:

[0148] Convolutional Neural Network (CNN): extracts local features of the image through multiple layers of convolutional layers and pooling layers;

[0149] Activation function (such as ReLU): increases the nonlinearity of the network and helps the network learn more complex features;

[0150] The feature extraction layer is located after the preprocessing layer to provide feature representation for the subsequent sequence modeling layer.

[0151] The Sequence Modeling Layer processes feature sequences and recognizes the order and structure of characters, including:

[0152] Recurrent Neural Networks (RNNs): such as LSTM (Long Short-Term Memory) or GRU (Gated Recurrent Unit), which can process sequence data;

[0153] Attention Mechanism: Dynamically adjust the weights of feature sequences to focus on more important features;

[0154] The sequence modeling layer receives the feature sequence output by the feature extraction layer and outputs the probability distribution of the character sequence.

[0155] The decoding layer converts the probability distribution output by the sequence modeling layer into the final character sequence, including:

[0156] CTC (Connectionist Temporal Classification) decoder: used to handle the mapping problem of indefinite length sequences, without the need to align the input and output sequences.

[0157] Beam Search: A heuristic search algorithm for finding the character sequence with the highest probability.

[0158] The decoding layer comes after the sequence modeling layer and is responsible for converting the model's internal representation into readable text output.

[0159] The loss function of the OCR recognition model includes:

[0160] CTC loss: used to train sequence-to-sequence mapping models that do not require alignment;

[0161] Cross entropy loss: used for classification tasks, calculating the difference between the predicted probability distribution and the true distribution;

[0162] During the training process, the loss function is used to calculate the error between the model output and the true label and is fed back to the optimizer.

[0163] The OCR recognition model also includes an optimizer, which minimizes the loss function by adjusting model parameters, such as Adam and SGD (stochastic gradient descent). The optimizer updates the network weights based on the gradient information provided by the loss function.

[0164] The relationship and functions of the various components of the OCR recognition model of this embodiment are summarized as follows:

[0165] Preprocessing layer → Feature extraction layer: Convert the original image into a form that the network can process and extract key features;

[0166] Feature extraction layer → sequence modeling layer: convert feature sequences into probability distributions of character sequences;

[0167] Sequence modeling layer → decoding layer: converts the probability distribution into the final text output;

[0168] Loss function and optimizer: During the training process, the loss function evaluates the model performance, and the optimizer adjusts the model parameters based on the feedback of the loss function.

[0169] The entire OCR model is an end-to-end system. From image input to text output, each part works closely together to complete the task of character recognition.

[0170] In some embodiments, the second security authentication module includes:

[0171] The quantum key generation unit is used to generate a set of quantum keys on the server side using quantum key distribution technology.

[0172] Dynamic key update unit, used to dynamically update the key according to the real-time nature of communication to ensure the timeliness and security of the key;

[0173] A multimodal encryption unit for encrypting communication data by combining symmetric encryption (such as AES) and asymmetric encryption (such as RSA);

[0174] The first security authentication module includes:

[0175] A quantum key receiving unit, used for receiving the quantum key distributed by the server;

[0176] The key synchronization unit is used to ensure that the client and server use the same key for encryption and decryption.

[0177] Specifically, the working principles of the second security authentication module and the first security authentication module are as follows:

[0178] The quantum key generation unit uses quantum key distribution (QKD) technology to generate a set of quantum keys on the server side. QKD uses the characteristics of quantum communication, such as quantum superposition and quantum entanglement, to ensure the absolute security of the key during transmission. Even if a third party attempts to eavesdrop, it will be discovered because of the non-replicability of the quantum state.

[0179] The dynamic key update unit monitors the real-time nature of communications and decides when to update the key based on factors such as the frequency and duration of communications. When appropriate, it generates a new quantum key and replaces the old one to ensure the timeliness and security of the key. This dynamic update mechanism can prevent the key from being used for a long time and thus reducing security.

[0180] The multimodal encryption unit combines symmetric encryption (such as AES, Advanced Encryption Standard) and asymmetric encryption (such as RSA, Rivest-Shamir-Adleman) technologies to encrypt communication data; symmetric encryption algorithms such as AES can be used to quickly encrypt large amounts of data, with the advantage of fast encryption and decryption speeds; or, asymmetric encryption algorithms such as RSA can be used to encrypt the key itself or a small amount of important data, with the advantage of providing security for key exchange, but with a large amount of calculations;

[0181] The quantum key receiving unit is used for the client to receive the quantum key distributed from the server through the QKD technology; this key is pre-generated in the quantum key generating unit on the server;

[0182] The key synchronization unit ensures that the client and server use the same key for encryption and decryption; this process involves the secure transmission and storage of the key;

[0183] The received quantum key is securely stored on the client to ensure that it is not leaked during use; the synchronized key is used to encrypt and decrypt the communication data to ensure the security of the communication process.

[0184] Through the collaborative work of these units, the second security authentication module and the first security authentication module together form a highly secure communication system; the distribution and dynamic update of quantum keys ensure the security of the keys, while multimodal encryption provides a flexible and powerful data protection mechanism; the entire system is designed to resist traditional and network attacks and ensure the security of user data.
