[0041] Figure 2 Schematic diagram of the process of uploading the portrait side image and the national emblem side image of the ID card to the ID card database in a method for document recognition and verification according to an embodiment of the present invention. Figure 2 As shown, when implementing a document identification and verification method provided by an embodiment of the present invention, in one embodiment, when the user document type is an ID card, an ID card upload page is displayed on the mobile device, and an ID card portrait image and an ID card national emblem image are uploaded to the ID card database, including:

[0042] Step 201: Analyze the user certificate type in the customer identity information; wherein the user certificate type includes: identity card, other certificates except identity card;

[0043] Step 202: When the user ID type is an ID card, the ID card upload page is displayed on the mobile device, first displaying the ID card portrait image upload page to guide the customer to upload the ID card portrait image to the ID card database;

[0044] Step 203: When the ID card portrait image is successfully uploaded to the ID card database or the number of failed uploads of the ID card portrait image to the ID card database reaches the first upload threshold, the ID card national emblem image upload page is displayed to guide the customer to upload the ID card national emblem image to the ID card database.

[0045] In the embodiment, the user ID type in the customer identity information is first analyzed. User ID types include ID cards and other ID cards. For example, ID cards other than ID cards may include passports, driver's licenses, social security cards, and other types. Then, if the user ID type is an ID card, an ID card upload page is displayed on the mobile device. The page first displays the ID card portrait image upload page, guiding the customer to upload the ID card portrait image to the ID card database. The customer then uploads the ID card portrait image to the ID card database by taking a photo or uploading an image from the mobile device's photo album. Finally, if the ID card portrait image is successfully uploaded to the ID card database or the number of failed uploads reaches a first upload threshold, the page then displays the ID card national emblem image upload page, guiding the customer to upload the ID card national emblem image to the ID card database. When the ID card portrait image fails to be uploaded to the ID card database, multiple upload opportunities can be provided. When the number of upload failures reaches the first upload threshold (for example, the first upload threshold is 3 times), re-uploading of the ID card portrait image is no longer allowed. You can skip uploading the ID card portrait image and proceed to the next step of uploading the ID card national emblem image. After the ID card national emblem image is successfully uploaded, you can jump back to the ID card portrait image upload page again to upload the ID card portrait image.

[0046] When specifically implementing a document identification and verification method provided by an embodiment of the present invention, in one embodiment, when the user's document type is a document other than an identity card, an other document upload page is displayed on the mobile device to guide the customer to upload other documents, and the uploaded other documents are saved in the other document database.

[0047] In an embodiment, when the user's ID type is an ID other than an ID card, such as a passport, an other ID upload page is displayed on the mobile device to guide the customer to upload other IDs. The customer uploads other IDs by taking photos or uploading images from the mobile device album. The information is no longer identified and the uploaded other IDs are saved in the other ID database. The counter staff manually confirms whether the images of the other IDs meet the requirements.

[0048] This embodiment of the present invention displays an upload page for ID or other ID images by document type, enabling accurate OCR recognition of ID cards. For ID images, OCR recognizes the name and ID number, then verifies and checks them online. OCR also recognizes the document's expiration date, notifying the user if the document is about to expire or has already expired. For other documents, manual verification is performed.

[0049] Figure 3 FIG. 1 is a schematic diagram of a process for obtaining customer ID card information and ID card expiration date in a method for document identification and verification according to an embodiment of the present invention. Figure 3As shown, when implementing a document identification and verification method provided by an embodiment of the present invention, in one embodiment, OCR recognition technology is used to recognize the portrait side image and the national emblem side image of the ID card to obtain the customer's ID card information and ID card expiration date, including:

[0050] Step 301: extracting the ID card face image from the ID card database, using OCR recognition technology to recognize the ID card face image, and obtaining the customer's ID card information;

[0051] Step 302: Compare the customer's ID card information with the customer's form content;

[0052] Step 303: If the comparison result matches, the ID card face image and the customer ID card information are displayed on the identification page of the mobile device;

[0053] Step 304: If the comparison result does not match, an error message is displayed and the user is asked to re-upload the ID card portrait image;

[0054] Step 305: After the customer's ID card information is compared with the customer's form content, the national emblem image of the ID card is extracted from the ID card database, and the national emblem image of the ID card is recognized using OCR recognition technology to obtain the ID card expiration date.

[0055] In the embodiment, the ID card portrait image is first extracted from the ID card database, and the ID card portrait image is recognized using OCR recognition technology to obtain the customer's ID card information; the customer's ID card information may include: name, ID number, address, photo and other information.

[0056] Then compare the customer's ID card information with the customer's form content;

[0057] If the comparison result matches, the ID card face image and the customer’s ID card information will be displayed on the identification page of the mobile device;

[0058] If the comparison result does not match, an error message will be displayed and the user will be asked to upload the ID card portrait image again;

[0059] Finally, after the customer's ID card information is compared with the content filled out by the customer, the national emblem image of the ID card is extracted from the ID card database, and the national emblem image of the ID card is recognized using OCR recognition technology to obtain the expiration date of the ID card.

[0060] Figure 4 FIG. 1 is a schematic diagram of a process for determining the status of an ID card in a method for document recognition and verification according to an embodiment of the present invention. Figure 4 As shown, when implementing a document identification and verification method provided by an embodiment of the present invention, in one embodiment, the method further includes:

[0061] Step 401: Compare the expiration date of the ID card obtained by identification with the current system date to determine the date difference;

[0062] Step 402: When the date difference is greater than the expiration threshold, the ID card status is determined to be normal;

[0063] Step 403: When the date difference is less than the near-expiry threshold, it is determined that the customer's ID card is about to expire, and the customer is prompted on the identification page that the ID card is about to expire;

[0064] Step 404: When the date difference is a negative number, it is determined that the customer's ID card has expired, and the customer is prompted on the identification page that the ID card has expired. The ID card portrait image and the ID card national emblem image stored in the ID card database are marked as expired, and the user is prompted to re-upload a new ID card portrait image and ID card national emblem image.

[0065] In the embodiment, in order to avoid customers returning to the branch counter multiple times due to expiration of their ID cards, it is necessary to compare the ID card expiration date with the current system date to determine whether the customer's ID card has expired or is about to expire. The specific process includes: first, comparing the ID card expiration date obtained by identification with the current system date to determine the date difference; then, when the date difference is greater than the expiration threshold, the ID card status is determined to be normal; for example, the expiration threshold is set to 3 months, and when the date difference is greater than 3 months, the ID card status is determined to be normal. Next, when the date difference is less than the expiration threshold, it is determined that the customer's ID card is about to expire, and the customer's ID card is about to expire is prompted on the identification page; for example, the expiration threshold is set to 3 months, and when the date is less than 3 months, it is determined that the customer's ID card is about to expire, and the customer's ID card is about to expire is prompted on the identification page, and the customer is prompted "The ID card is about to expire, please replace it in time", and the customer can re-upload for identification or proceed to the next step; finally, when the date difference is a negative number, it is determined that the customer's ID card has expired, and the customer's ID card is prompted on the identification page that it has expired, and the ID card portrait image and ID card national emblem image stored in the ID card database are marked as expired, and the user is prompted to re-upload a new ID card portrait image and ID card national emblem image; for example, when the customer's ID card has expired, a prompt "The ID card has expired, please re-upload" is given, and the customer can re-upload. The embodiment of the present invention identifies the expiration date of the ID card based on OCR and reminds the customer in time, avoiding the customer from returning to the branch counter multiple times due to the expiration of the ID card.

[0066] Figure 5 FIG. 1 is a schematic diagram of an ID card expiration processing process of a method for document identification and verification according to an embodiment of the present invention. Figure 5 As shown, when implementing a document identification and verification method provided by an embodiment of the present invention, in one embodiment, the method further includes:

[0067] Step 501: When the user re-uploads a new ID card portrait image and ID card national emblem image, the new ID card national emblem image is recognized using OCR recognition technology to obtain the new ID card expiration date, and the new date difference between the new ID card expiration date and the current system expiration date is determined to be a negative number.

[0068] Step 502: When the new date difference is not a negative number, determine whether the ID card status is normal or about to expire based on the expiration threshold;

[0069] Step 503: When the new date difference is still a negative number, the customer's ID card is determined to be expired, and the user is repeatedly prompted to re-upload a new ID card portrait image and ID card national emblem image for identification and date difference determination until the number of re-uploads reaches the second upload threshold. The user is terminated from re-uploading, and the result of this document verification is output as failure. The customer is prompted on the mobile device to go to the counter to handle the business.

[0070] In the embodiment, when it is determined that the customer's ID card has expired, it is necessary to guide the user to re-upload a new ID card portrait image and ID card national emblem image and perform the judgment again. The main process includes:

[0071] First, when the user re-uploads a new ID card portrait image and ID card national emblem image, the new ID card national emblem image is recognized using OCR recognition technology to obtain the new ID card expiration date, and then the new date difference between the new ID card expiration date and the current system is determined to be a negative number;

[0072] Then, when the new date difference is not a negative number, the ID card status is judged to be normal or about to expire based on the expiration threshold; when the new date difference is greater than the expiration threshold, the ID card status is judged to be normal; when the new date difference is less than the expiration threshold, the customer's ID card is judged to be about to expire; finally, when the new date difference is still a negative number, the customer's ID card is judged to have expired, and the user is repeatedly prompted to re-upload a new ID card portrait image and ID card national emblem image for identification and date difference judgment until the number of re-uploads reaches the second upload threshold, the user is terminated from re-uploading, the result of this ID card verification is output as failure, and the customer is prompted on the mobile device to go to the counter to handle the business. When re-uploading the new ID card portrait image and ID card national emblem image, multiple upload opportunities can be provided. When the number of upload failures reaches the second upload threshold (for example, the second upload threshold is 4 times), the user is terminated from re-uploading. At this time, re-uploading of the new ID card portrait image and ID card national emblem image is no longer allowed, and a return to homepage button is displayed to the user. The customer clicks the button to exit this function, the result of this ID card verification is output as failure, and the customer is prompted on the mobile device to go to the counter to handle the business.

[0073] Figure 6 FIG. 1 is a schematic diagram of a certificate network verification process of a certificate identification and verification method according to an embodiment of the present invention. Figure 6 As shown, when implementing a document identification and verification method provided by an embodiment of the present invention, in one embodiment, based on the customer identity information, the customer ID card information and the ID card expiration date, connecting to the citizen identity information system for online verification, outputting the document verification results, and feeding them back to the mobile device, the method includes:

[0074] Step 601: Connect to the citizen identity information system for online verification based on the customer's identity information, customer ID card information, and ID card expiration date;

[0075] Step 602: When the online verification is successful, the certificate verification result is output as passed and fed back to the mobile device to continue business processing;

[0076] Step 603: When the online verification fails, the result of the document verification is output as failure, and the customer is prompted on the mobile device to go to the counter to handle the business.

[0077] In the embodiment, when conducting online verification on customers, it mainly includes: first, connecting to the citizen identity information system for online verification based on the customer's identity information, customer ID card information and ID card expiration date; then, when the online verification passes, outputting the result of this document verification as passed, and feeding back to the mobile device to continue business processing; finally, when the online verification fails, outputting the result of this document verification as failed, and prompting the customer to go to the counter to handle the business on the mobile device.

[0078] Figure 7 This is a flow chart of a method for document identification and verification according to an embodiment of the present invention. Figure 7 As shown, the following briefly describes a document identification and verification method provided by an embodiment of the present invention in combination with a specific scenario:

[0079] The embodiment of the present invention also provides a process of a document identification and verification method, which mainly includes:

[0080] 1. Obtain the customer's identity information in advance based on the business application document filled out by the customer, and display the ID card upload or other document upload page to the customer based on the user's ID type.

[0081] 2. When the customer's ID is an ID card, the portrait side image of the ID card will be displayed for upload first. After the customer takes or uploads the image, OCR will recognize the image information and extract the ID card name and ID number. The system will compare the recognized name and ID number with the customer's form content. If they match, the image and recognition information will be displayed on the page. Click "Go directly to the next step" to proceed to the next step of uploading the national emblem side image. If they do not match, an error prompt will be given and the user will be asked to upload again. If the OCR-recognized information cannot be successfully compared with the customer's form content after uploading three times, the customer will be prompted to continue uploading or skip uploading the portrait side image and go directly to uploading the national emblem side image.

[0082] Enter the national emblem image upload. After the customer takes or uploads the image, OCR recognizes the image information, extracts the ID card expiration date information, and compares the ID card expiration date with the current system date. When the date difference is within 3 months (that is, the ID card will expire within 3 months), the customer will be prompted "The ID card is about to expire, please replace it in time", and the customer can re-upload for recognition or proceed to the next step; when the date is a negative number (that is, the ID card has expired), the customer will be prompted "The ID card has expired, please re-upload", and the customer can re-upload. When the upload times reach 3 times and the ID card is judged to be expired, the customer will no longer be allowed to try to upload, and a return to homepage button will be displayed to the user. The customer clicks the button to exit this function; if the customer date difference recognition fails, the failure page will be displayed, and the customer is asked to re-upload; when the recognition fails after 3 uploads, the customer can continue to upload or the customer can directly proceed to the next step.

[0083] After the customer completes or skips uploading the ID card portrait and national emblem images, the system connects to the citizen identity information system to conduct an online verification of the customer information. If the verification is passed, the process is completed. If the verification fails, the process ends and the customer is prompted to go to the counter to handle the business.

[0084] 3. When the customer information is other documents (such as a passport), the ID image will be displayed and uploaded. After the customer takes or uploads the image, the information will no longer be recognized. The customer will be directly asked to confirm the upload, and the counter staff will manually confirm whether the ID image meets the requirements.

[0085] In one embodiment, customers use their mobile devices to take a photo or upload their ID according to the on-screen prompts. For ID cards, the system uses OCR technology to identify the front and back of the document, determining whether the information matches the information entered by the person handling the service and whether the document is nearing or expired. After confirmation by the customer, the identified information is uploaded to an online verification system to determine whether the customer information is authentic and meets the service processing requirements. For other IDs, no recognition or verification is performed. After the user uploads the ID image, the counter staff will manually verify it.

[0086] This embodiment of the present invention displays an upload page for ID or other ID images by document type, enabling accurate OCR recognition of ID cards. For ID images, OCR recognizes the name and ID number, then verifies and checks them online. OCR also recognizes the document's expiration date, notifying the user if the document is about to expire or has already expired. For other documents, manual verification is performed.

[0087] The present invention uses OCR to identify and compare information, thereby preventing customers from transmitting incorrect documents and reducing the manual comparison costs at the counter; the present invention uses OCR to identify the expiration date of the document and promptly reminds the customer, thereby avoiding the customer from returning to the branch multiple times due to the expiration of the document; the present invention verifies the customer information online and promptly reminds customers who fail the verification, thereby avoiding the customer from returning to the branch due to identity failure to meet business requirements.
