The method provided by the embodiments of the present invention can be applied to any required electronic device, for example, it can be a server, terminal and other electronic devices, which are not specifically limited here. For the convenience of description, it is referred to as an electronic device in the following.

[0052] According to one aspect of the embodiments of the present application, a method embodiment of a method for processing certificate information is provided. Figure 1 A flowchart of a method for processing certificate information provided in an embodiment of the present application, such as Figure 1 As shown, the method includes:

[0053] Step S11, obtaining a target image to be processed, wherein the target image is an image obtained by scanning a target document.

[0054] In the embodiment of the present application, step S11, obtaining the target file to be processed, includes the following steps A1-A3:

[0055] Step A1, obtaining an initial file obtained by scanning a target document with a scanning device.

[0056] The method provided in the embodiment of the present application is applied to a control terminal, which receives a scanning instruction triggered by a user, controls a scanning device to scan a target document according to the scanning instruction, and then sends the scanned initial file to the control terminal after the scanning device completes scanning the target document.

[0057] Step A2, determining the initial file to obtain the file format of the initial file.

[0058] Step A3: when the file format does not match the preset file format, convert the format of the initial file to obtain a target image in the preset file format.

[0059] In an embodiment of the present application, when the file format of the initial file does not match the preset file format, the control terminal will automatically convert the format of the initial file to obtain a target image in the preset file format. For example, if the file format of the initial file is a PDF file format, the control terminal will convert the initial file in PDF file format to obtain a target image in JPG format.

[0060] Step S12, extracting target certificate information of the target certificate from the target image, and encoding based on the target certificate information to obtain a target feature code.

[0061] In the embodiment of the present application, step S12, extracting target document information of the target document from the target image, includes the following steps B1-B3:

[0062] Step B1, inputting the target image into the first detection model so that the first detection model extracts key features in the target image, and determines at least one region of interest in the target image according to the key features, wherein the key features correspond to the regions of interest one by one.

[0063] In the embodiment of the present application, the target image is input into the first detection model, and the first detection model extracts the image features in the target image, and obtains the key features based on the image features. The key features may be: text features and image features in the certificate, and then the region of interest in the target image is determined based on the text features. The region of interest may be the bounding box of the certificate information area and the bounding box of the certificate photo area. Among them, the text features correspond to the certificate information area, the image features correspond to the certificate photo area, and the certificate photo area may be a face image.

[0064] Step B2, segmenting the target image based on the region of interest to obtain an image of interest.

[0065] In the embodiment of the present application, after the region of interest is obtained, the target image is segmented according to the region of interest to obtain an image of interest, which includes: a face image and a text image.

[0066] Step B3, input the image of interest into the second detection model, so that the second detection model calls a sub-detection model that matches the key features according to the key features corresponding to the image of interest, and extracts the target document information from the image of interest based on the sub-detection model.

[0067] In the embodiment of the present application, the image of the region of interest is input into the second detection model, and the second detection model detects the text image according to the text detection sub-model corresponding to the text feature to obtain the document text content in the target document. At the same time, the second detection model extracts the face image according to the image detection sub-model corresponding to the image feature to obtain the facial features (contour features and facial features, etc.) corresponding to the face image, and then adds the facial features to the background image of the preset background color to obtain the target face image. Finally, the target face image and the document text content are determined as the target document information.

[0068] In the embodiment of the present application, after extracting the target certificate information, the target certificate information is encoded to obtain the target feature code. The purpose of encoding the target feature code is to convert the target feature code into a code recognizable by the classification model, so as to facilitate the classification of the certificate information.

[0069] Step S13, determining the target information type corresponding to the target certificate information according to the target feature code.

[0070] In an embodiment of the present application, step S13, determining the target information type corresponding to the target certificate information based on the target feature code, includes: inputting the feature code information into the classification model, so that the classification model determines the target information type corresponding to the feature code information based on the correspondence between the preset feature code information and the preset information type.

[0071] In the embodiment of the present application, the target feature coding information is input into the classification model, and the classification model identifies the feature coding information and determines the information type corresponding to the feature coding information. For example, when the target certificate is a real estate certificate, the information type may be: right holder, co-ownership, real estate unit number, area, term of use, etc. When the target certificate is a driver's license, the information type may be: personal information, date of receipt, permitted vehicle type, and validity period.

[0072] Step S14: Generate structured information of the target certificate based on the target information type and the target certificate information.

[0073] In the embodiment of the present application, step S14, generating structured information of the target certificate based on the target information type and the target certificate information, includes the following steps C1-C4:

[0074] Step C1, obtaining an information template library, wherein the information template library stores a plurality of initial templates for storing document structured information, and the initial templates include a plurality of storage areas of different storage types.

[0075] Step C2, determining the similarity between the target information type and the storage type corresponding to each storage area in the initial template.

[0076] Step C3, determining the initial template with a similarity greater than a preset similarity as the target template.

[0077] Step C4, writing the target certificate information into the corresponding storage area in the target template to generate structured information of the target certificate.

[0078] In an embodiment of the present application, after determining the target feature code and the information type, a matching initial template is obtained from the information template library according to the information type, and the initial template includes: storage areas arranged in a tree structure. Specifically, the storage type of each storage area of ​​the initial template in the information template library can be obtained, for example: the storage type can be: numerical type, character type, image type, etc. Then, the similarity between the target information type and the storage type corresponding to each storage area in the initial template is calculated. If the similarity of each storage area in the initial template is greater than the preset similarity, the initial template is determined as the target template. Then, the corresponding storage area in the target template of the target certificate information is arranged in a tree shape, so that structured information is finally obtained.

[0079] In the embodiment of the present application, the method further includes the following steps D1-D3:

[0080] Step D1, when the storage type corresponding to the storage area does not match the target information type, a template creation request is sent to the client.

[0081] Step D2, when a template creation event is monitored, a newly added template is obtained based on the template creation event, wherein the newly added template carries multiple storage areas, and the template creation event is triggered after the client receives a template creation request.

[0082] Step D3, write the target certificate information into the corresponding storage area in the newly added template to generate structured information of the target certificate.

[0083] In the embodiment of the present application, when the storage type corresponding to the storage area does not match the target information type, a template creation request is sent to the client, which is the terminal where the user operates. After receiving the template creation request, the client will display the template creation request, so that the user can create a template based on the template creation request. When the client detects that the template creation is completed, the control terminal will monitor the template creation event, and then obtain the newly added template based on the template creation event, and write the target certificate information into the corresponding storage area in the newly added template.

[0084] The method provided in the embodiment of the present application directly detects the target image corresponding to the target certificate, extracts the certificate information of the target certificate, and provides a basis for quickly classifying the certificate information by encoding the certificate information. After determining the information type, the structured information of the target certificate is automatically generated. There is no need to manually design complex post-processing rules, which reduces business time and improves processing efficiency.

[0085] Figure 2 A flow chart of a control method for a smart home device provided in an embodiment of the present application, such as Figure 2 As shown, the method includes:

[0086] Step S21, detecting the security level corresponding to each target certificate information in the structured information.

[0087] Step S22, obtaining encryption rules corresponding to the current period from the server.

[0088] Step S23, encrypting the target certificate information in the structured information whose security level is greater than the preset level based on the encryption rule to obtain the encrypted structured information.

[0089] Step S24, obtaining the timestamp corresponding to the encryption rule.

[0090] Step S25: Store the timestamp in association with the encrypted structured information.

[0091] In the embodiment of the present application, after generating the structured information of the target certificate, the control terminal obtains the preset security information library, detects whether each target certificate information in the structured information matches the preset security information in the preset security information library, and determines the security level corresponding to the matched target certificate information. Then, the target certificate information in the structured information whose security level is greater than the preset level is encrypted according to the encryption rule to obtain the encrypted structured information. At the same time, the timestamp corresponding to the encryption rule is obtained, and the timestamp is associated with the encrypted structured information and stored.

[0092] Specifically, the encryption rule includes a character mapping table, and the character mapping table includes: initial characters and mapping characters corresponding to the initial characters, the initial characters include: letters, Chinese characters and numbers, and the mapping characters include: special symbols, letters, numbers, etc. Therefore, when encrypting the target certificate information with a security level greater than the preset level, the characters carried in the target certificate information with a security level greater than the preset level can be determined, and the mapping characters corresponding to the characters are queried from the character mapping table, the encrypted target certificate information is generated based on the obtained mapping characters, and the encrypted structured information is generated based on the encrypted target certificate information.
