The intelligent signing system can help the user to improve signing efficiency and signing quality, reduce signing risk and cost, and is an efficient, safe and reliable contract signing solution.

In one embodiment of the present invention, the intelligent signature system receives contract information input by a user a in the intelligent signature system, generates a primary contract according to the contract information, performs format conversion, image processing and text recognition on the primary contract, and obtains a standard contract, including:

The working principle of the technical scheme is as follows: the intelligent signature system receives contract information input by a user A in the intelligent signature system, and generates a primary contract according to the contract information; preprocessing operation of format conversion, image processing and character recognition is carried out on the primary contract; the intelligent signature system obtains the standard contract through the preprocessing operation.

The technical effects of the technical scheme are as follows: the contract information input by the user in the intelligent signature system may contain more contents such as texts, pictures and tables, and if signing operation is directly performed, the problems of non-uniform format, unclear pictures, unrecognizable characters and the like may exist. Thus, an intelligent signing system, which can format-convert input contract information to generate a primary contract according to contract contents, generally needs to perform preprocessing operations to improve signing efficiency and signing quality. Compared with the originally input contract information, the primary contract has more standard and unified format, and is convenient for subsequent signing and management. When the contract contains non-text information such as pictures, the intelligent signature system can process images, correct and optimize the pictures so as to ensure the definition and the readability of the pictures. This will help ensure that the contract is signed while all contract terms and treaties can be clearly read, thereby reducing contract disputes. The intelligent signature system can perform character recognition on the primary contract, and recognize the character content in the contract and convert the character content into a text format. This will make the contract content easier to understand and analyze, enhancing the contract's automated, searchable features; through the preprocessing operation, the intelligent signature system can generate a normalized contract. The standardized contract has the advantages of clear format, accurate content, character recognition and the like, can reduce contract dispute risks, and is convenient for a user to use a subsequent management processing tool to carry out subsequent management.

In one embodiment of the present invention, the intelligent signature system sets a signature style for the standard contract to obtain a signed contract, performs identity authentication on the user a, and uploads the signed contract to a contract signing port when the intelligent signature system receives the signed contract selected by the user a after the identity authentication is completed, including:

The setting rule of the exclusive signature in the invention is based on the relevant regulation of the regulation and does not exceed the legal regulation range.

The technical effects of the technical scheme are as follows: the intelligent signature system sets the font style, the stroke style and the color style for the standard contract, thereby improving the signature aesthetic degree and the recognizability, and simultaneously facilitating the user to recognize and position on the contract.

The intelligent signature system can also provide personalized seals, a user can write self-signatures on a handwriting port, and the system can perform clear processing through an image processing technology. The processed signature can be provided with a special signature style, a stroke style, a color style and the like, and finally a special seal is generated, so that other series of operations of different contracts can be signed conveniently.

The technical effects of the technical scheme are as follows: through double verification of the identity of the user, the user signing the contract is ensured to be real and legal, risks such as identity disguise and the like are avoided, and the reliability of the identity verification is improved. The signed contract is authenticated through the CA certificate, so that the integrity and legal effectiveness of the contract are ensured, and the authentication of the contract is enhanced. In the process of contract file generation, if any user fails to pass the authentication, the system automatically prohibits contract generation and ensures the safety and the integrity of the contract.

Meanwhile, the system can also automatically detect whether unfilled content, format errors and other problems exist in the contract, prompt and correct the problems, and ensure the accuracy and the integrity of the contract. The integrated uploading module is used for enabling the intelligent signature system to support user-defined signature patterns and positions, and a user can select corresponding signature patterns and positions according to own needs so as to achieve the optimal signature effect. The intelligent signature system supports various identity authentication modes, such as digital certificate authentication, face recognition authentication, fingerprint recognition authentication, short message verification and the like. The user must pass a valid identity authentication before proceeding with the signing operation to ensure the legitimacy and security of the signing action. The contract signing module is used for enabling the intelligent signing system to support various signing operation modes, such as manual signing, digital signing, public signature and the like. The user can select the corresponding signing operation mode according to different signing requirements and situations, and the system can automatically record the signing process for subsequent auditing and management. The contract archiving module is used for supporting the automatic archiving and backup of the signed contract by the intelligent signing system, and ensures the safety and traceability of the contract. Meanwhile, the user can also refer to the signed contract and the signed record at any time through the system so as to be convenient for later processing and management.

In one embodiment of the present invention, the information processing module includes:

The working principle of the technical scheme is as follows: the information input module is used for enabling the intelligent signature system to receive contract information input by the user A in the intelligent signature system, and generating a primary contract according to the contract information; the information preprocessing module is used for preprocessing the primary contract to perform format conversion, image processing and character recognition; and the standard contract obtaining module is used for the intelligent signature system to obtain the standard contract through the preprocessing operation.

The technical effects of the technical scheme are as follows: through the information input module, the user A can conveniently input contract information in the intelligent signature system, so that the time and the workload of manual operation are reduced, and the efficiency is improved. The intelligent signature system inputs contract information through the information input module and combines preprocessing operation to generate a primary contract. The primary contract is more accurate in form and content for subsequent operations. Through the format conversion, image processing, character recognition and other operations of the information preprocessing module, the format and the attribute of the primary contract can be quickly converted, and the preprocessing efficiency and accuracy are improved. Through the standard contract obtaining module, the intelligent signing system can generate a standard contract according to the primary contract, so that the accuracy of the content of the signed contract is ensured, and the reliability and the integrity of the contract are further enhanced.

In one embodiment of the present invention, the contract uploading module includes:

The working principle of the technical scheme is as follows: the exclusive style setting module is used for enabling the intelligent signature system to set signature styles for the standard contract, wherein the signature styles comprise font styles, stroke styles and color styles; in the intelligent signature system, after the intelligent signature system receives a self signature written by a handwriting port of a user A, the self signature is subjected to clear processing through an image processing technology, an exclusive font style, a special stroke style and a special color style are set for the self signature, an exclusive seal is set, the exclusive font style, the special stroke style, the special color style and the exclusive seal are set for the self signature after the setting is completed and stored in a database of the intelligent signature system, exclusive numbers are set for the self signature and the exclusive seal, and when the intelligent signature system monitors a signature operation request sent by a user, the intelligent signature system directly calls the exclusive numbers from the database and sends the exclusive numbers to a user end of the user A; the identity authentication module is used for enabling the intelligent signature system to carry out identity authentication on the user A, when the intelligent signature system monitors that the identity authentication fails, re-authentication is carried out, after three times of repeated authentication are carried out and the authentication fails, a problem solving window is popped up, and the user A can solve the problem of authentication failure through the problem solving window; and the signing and uploading module is used for uploading the signing contract to the contract signing port by the intelligent signing and signing system when the intelligent signing and signing system receives the signing contract selected by the user A after the intelligent signing and signing system monitors that the identity authentication is successful. The identity authentication module can also be replaced by a biological recognition technology and a video authentication technology; the biological recognition technology can use human body biological characteristics such as fingerprint, iris, facial recognition and the like to carry out identity verification, thereby achieving the purposes of signing and stamping. This way, the identity authenticity of the signer can be ensured, but strict security control measures need to be taken. Identity authentication and signing are carried out through a video technology, and whether a signer is truly effective or not is judged by utilizing factors such as voice, facial expression, action and the like in a video, so that signing and stamping effects are realized. Also, strict security control measures need to be taken to prevent the video from being tampered with or falsified.

The technical effects of the technical scheme are as follows: the exclusive style setting module enables the intelligent signature system to set font style, stroke style and color style for the standard contract, thereby improving signature aesthetic degree and recognizability, and simultaneously facilitating the user to recognize and position on the contract. Based on the text format of the canonical contract, the intelligent signing system can set different signature styles according to the contract format. The user can select a signature pattern which is suitable for and meets the requirements of the contracts from a signature library provided by the system, and the signing requirements of the user on different contracts can be met. The identity authentication module is used for authenticating the identity of the user A, so that risks such as identity impersonation can be effectively avoided, and the safety and reliability of authentication are improved. When the identity authentication fails, the system provides authentication operation again, so that the user is allowed to carry out authentication again, and the accuracy and the reliability of the authentication are improved. When the user repeatedly performs identity verification but fails, the system automatically pops up a problem solving window through which the user can solve the authentication problem, so that the user experience friendliness and convenience are improved. The signing and uploading module enables the user A to rapidly and conveniently upload the required signing contract to the contract signing port, so that the signing efficiency and accuracy of the contract are improved.
