[0038] The location management module supports multiple default signature location configurations and provides API interfaces and page configurations to implement management configuration information functions.

[0039] This module implements configuration information storage and access through json unstructured configuration, which also supports user-defined configuration; among them, the default supported configurations include: 1) the page and signature coordinates of the protocol file; 2) the page number of the protocol file and the signature keywords in the document; 3) the page number of the protocol file and the circular algorithm signature.

[0040] Positioning algorithm module: Based on the configuration of the positioning management module, read the configuration information and parse it. After parsing, it matches different algorithms based on different configuration types to calculate the signature position of the document to be signed.

[0041] The positioning algorithm module reads configuration information in JSON format and parses it using a JSON parsing tool.

[0042] Different types are matched by parsing the key in the json configuration information. According to different type matching algorithms, the signature position is calculated based on the signature information including page number, coordinates, and number of signatures given in the configuration information.

[0043] Algorithm types include:

[0044] Coordinate algorithm: Calculate the coordinates of any point on the transition curve based on the rotating coordinate system method, and apply the mathematical model to calculate the specific position coordinates ((X1-X2) 2 +(Y1-Y2) 2 ); X and Y are the horizontal and vertical coordinates respectively;

[0047] The present invention also provides an automatic electronic signature positioning method based on an intelligent algorithm, the method comprising:

[0048] Step S1: When an enterprise initiates a trade application in the system, the system generates a corresponding trade agreement document based on the user's trade behavior.

[0049] Step S2: The system transmits the protocol file to the positioning management module through the interface.

[0051] Step S4: The positioning algorithm module transmits the calculated signature position and protocol file to the quick signature module through the interface. The quick signature module parses the protocol file and synthesizes the seal into the corresponding file in the file stream based on the acquired signature position, and returns the signed file.

[0052] Embodiment 2:

[0053] This example further describes the present invention based on Example 1.

[0054] The present invention provides an automatic electronic signature positioning system based on an intelligent algorithm. Through the default configuration of the positioning management module, the positioning algorithm module automatically calculates the position of the signature in the agreement. Any position in the agreement can be signed through the configuration of the positioning management module, which also satisfies the dynamic and flexible signature positions of the trading parties. The algorithm automatically calculates the signature position and realizes the electronic signature. The system specifically includes the following contents:

[0055] Positioning management module: mainly provides API interface and page configuration to manage configuration information, and implements configuration information storage and access through JSON unstructured configuration;

[0056] This module supports flexible configuration of multiple default signature position configurations through a flexible json unstructured configuration protocol. The json unstructured configuration also supports user-defined configurations. The default supported configurations include: 1. The page and signature coordinates of the protocol file; 2. The page number of the protocol file and the signature keywords in the document (supports repeated signatures or signing only once); 3. The page number and circular algorithm signature of the protocol file.

[0057] The signature location is configured through the json unstructured configuration protocol, such as the default configuration type=1,2,3 mentioned later. The positioning management module provides an external RestApi interface, and the default supported configuration information can be modified by entering the administrator username and password. The positioning management module itself provides a management page to modify the default supported configuration information.

[0058] The default configuration supports three default formats of type 1, 2, and 3. You can also configure the positioning through the API interface or management page provided by the positioning management module. According to your needs, you can sign the same page multiple times and make different adjustments to the signature positions of different pages. Because it is an unstructured parameter, users can freely combine the configuration at will. Custom configuration provides a series of personalized tags including (page number, number of signatures, keywords, coordinates, keyword offset, blank space, etc.). That is, it supports the configuration of different algorithm types, corresponding to the key value type = 1, 2, 3, supports the page number key value in the configuration document as pageIndex, supports the coordinate x-axis in the configuration document: coordinateX; supports the coordinate y-axis in the configuration document: coordinateY; supports user-defined configuration, the corresponding key value is the information in the customer, which can also include the configuration of the above key values.

[0059] Positioning algorithm module: This module is based on the json unstructured configuration of the positioning management module. It parses the unstructured configuration through the protocol (configuration information is all data in json format, and only needs to be parsed through the json parsing tool). After parsing, it matches different algorithms based on different configuration types (there are specific key generation types in the json configuration information, and parsing and matching can be performed according to this key). (Different algorithms are matched according to different keys, and then the algorithm is calculated). After parsing the agreement document to be signed, the algorithm calculates the signature position of the document to be signed through different configuration types. That is, based on the key information of the signature already given in the configuration information, such as page number, coordinates, number of signatures, etc., the signature position can be accurately calculated through the algorithm.

[0060] Specifically, different location algorithms are matched according to different key types through the configuration information of the location management module:

[0061] 1. The coordinate algorithm is based on the rotation coordinate system method and can be used to calculate the coordinates of any point on the transition curve. The mathematical model is used to calculate the specific position coordinates ((X1-X2) 2 +(Y1-Y2) 2 );

[0062] 2. The keyword algorithm reads the coordinates of the keyword by parsing the file stream (findText).

[0063] Quick signature module: This module reads the agreement document to be signed based on the signature position calculated by the positioning algorithm module, and synthesizes the corresponding seal into the corresponding position of the document, thereby achieving quick signature.

[0064] The fast signature module mainly includes two major technical points: 1) reading the PDF file stream and parsing the PDF protocol document stream through Apache PDF Box; 2) synthesizing the PDF seal into the PDF document stream through OpenVC; This module reads the agreement document to be signed based on the signature position calculated by the positioning algorithm module, and synthesizes the corresponding seal into the corresponding position of the document.

[0065] The overall method for achieving the purpose of the invention by cooperating between the modules specifically includes the following:

[0066] Step 1. When an enterprise initiates a financial trade application in the digital financial system, the digital financial system will generate a corresponding trade agreement document based on the user's trade behavior. This document will contain all the contents of the current trade and be consistent.

[0067] Step 2. The digital financial system will transmit the generated protocol file to the positioning management module through the interface. After receiving the file, the positioning management module will start to read and parse the configured JSON unstructured configuration information. After the parsing configuration is completed, a positioning algorithm model will be obtained (hybrid positioning algorithm: first use a rule-based positioning algorithm for preliminary positioning, and then use a coordinate algorithm based on image processing for fine adjustment). This model will contain information about the protocol file and the location information of the signature, etc., and support signatures in multiple locations.

[0068] After the parsing configuration is completed, the positioning algorithm model is obtained as follows: the configuration in Json format itself contains keys according to different algorithm types. Each different type corresponds to a different algorithm in the positioning algorithm module. For example, the key value corresponding to the hybrid positioning algorithm is type='hybirdPosit', the key value corresponding to the document coordinate algorithm is type='docCoordinates', and the key value corresponding to the keyword algorithm is type='docKeyword'. Therefore, by parsing the value of this type in the configuration, the corresponding model algorithm in the algorithm model can be matched.

[0069] Step 3. The positioning management module transmits the positioning algorithm model and protocol file to the positioning algorithm module through the interface. After receiving the algorithm model and protocol file, the positioning algorithm module performs index-driven calculation on the algorithm model. The index will quickly match the algorithm driver and perform calculation based on the transmitted algorithm model. The algorithm driver can quickly calculate the signature position through the algorithm model.

[0070] Step 4. The positioning algorithm module transmits the calculated signature position and protocol file to the quick signature module through the interface. The quick signature module parses the protocol file and synthesizes the seal into the corresponding file in the file stream based on the acquired signature position and returns the signed file.

[0071] Specific examples are as follows:

[0072] 1. Enterprise A initiates a financing application transaction to Bank B through the digital financial trade system. The trade system receives the financing application request from Enterprise A, applies for multiple financing agreement documents based on Enterprise A's corporate information and financing application information, and transmits the financing agreement documents to the positioning management module through the interface.

[0073] 2. After receiving the financing agreement file from enterprise A, the positioning management module starts to read and parse the configured (default, custom) json unstructured configuration information. After the parsing configuration is completed, a positioning algorithm model will be obtained. The positioning model contains the information of the financing agreement and the signature location information, and then this model information is pushed to the positioning algorithm module.

[0074] 3. After the positioning algorithm module receives the algorithm model data of the financing application, it first parses the model data and performs index-driven calculations on the algorithm model. The index will quickly match the algorithm driver based on the incoming algorithm model and perform calculations. The algorithm driver can quickly calculate the signature position through the algorithm model.

[0075] 4. The positioning algorithm module transmits the calculated signature position and protocol file to the quick signature module through the interface. The quick signature module parses the file stream of the protocol file and synthesizes the seal into the corresponding file in the file stream based on the acquired signature position.

[0076] 5. The quick signature module returns the signed document to the digital financial trade system, and the trade system then presents the signed agreement document.

[0077] The embodiment of the present invention provides an automatic electronic signature positioning system and method based on an intelligent algorithm. Through the default configuration of the positioning management module, the position of the signature in the agreement is automatically calculated through the positioning algorithm module. Any position in the agreement can be signed through the configuration of the positioning management module, which can also well meet the dynamic and flexible signature positions of all trading parties, realize the algorithm to automatically calculate the signature position, and realize the electronic signature.
