BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 This is a schematic diagram of the structure of an enterprise information management integration platform based on big data according to an embodiment of the present invention;

[0022] Figure 2 The present invention is a flowchart of an enterprise information management integration method based on big data according to an embodiment of the present invention. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 The embodiment of the present invention provides an enterprise information management integration platform based on big data, including: an information entry module, a bill classification module, a bill processing module, a signature generation module and a supervision verification module.

[0025] In this embodiment, the information entry module is used to obtain corporate business information and bill information, wherein blank bill images, purchaser's business license images and seller's business license images are obtained by scanning with a scanning device or uploading images, and converted into electronic bills and electronic business licenses.

[0026] Furthermore, the image uploading of the information entry module includes manual uploading and batch entry through the API interface. An upload file button is constructed in the information entry module. The invoice images and business license images to be uploaded are selected and the upload file button is clicked. The system automatically converts the uploaded images into electronic receipts and electronic business licenses, and stores them in the database. An API interface is constructed in the information entry module, and through this interface, receipts and business license images in quantities greater than two are batch uploaded to the information entry module and stored in the database.

[0027] In this embodiment, the bill preset module is used to classify and set up electronic bills, wherein characters in the electronic bill are recognized through optical character recognition, and a bill data dictionary is constructed. The characters are bidirectionally matched with the bill data dictionary using an inverse maximum matching algorithm to obtain the bill header information and bill body information in the characters. The bill type is automatically classified and stored according to the bill header information for use as a bill template, and a placeholder box is set according to the bill body information.

[0028] Furthermore, the main information of the bill includes the invoice number, invoice date, purchaser information, seller information, remarks and invoice issuer. The bill preset module automatically classifies the bills according to value-added tax bills, ordinary bills and professional bills, and generates corresponding classification labels. The bill preset module uses OCR technology to perform text recognition on the bill image, extracts key text information on the bill, such as invoice header, tax number, invoice code, and matches the recognized invoice header information with the preset rule library, which contains the words "special value-added tax invoice", "special invoice" and "ordinary invoice".

[0029] According to the above technical solution, a bill data dictionary Word_freq = {key1:value1, key2:value2…keyN:valueN} is established, wherein the key value is a word, and the value is the word frequency corresponding to the key. The bill header information and the bill body information in the characters are obtained through optical character recognition. If the bill header information and the bill body information are not in Word_freq, the word is put into Word_freq as a key; if the word appears, the word frequency value corresponding to the key is increased by one.

[0030] Among them, the default high-frequency words are the words that appear more than 10 times in the project. If there are more than 500 words that appear more than 10 times, the 500 high-frequency words are put into words_f.txt to get the final high-frequency word library. Finally, starting from the beginning of the bill text, scan backward word by word, and use the high-frequency word library to match the characters in the bill. When matching, the longest word is given priority to ensure that the key information characters in the bill are matched, and a placeholder box is set after the key information characters.

[0031] In this embodiment, the bill processing module is used to generate an electronic bill to be signed, wherein the text portion of the electronic bill and the electronic business license is extracted as characters through optical character recognition, and the characters of the corporate industrial and commercial information in the electronic business license are obtained and replaced with the placeholders on the bill template to generate an electronic bill to be signed, the text portion is extracted as TXT text, and the txt text is converted into Song font text.

[0032] Furthermore, the bill processing module and the signature generation module perform data backup when performing electronic bill operations, wherein the data backup is backed up and stored in a database, and the data backup data is read when restoring the data.

[0033] In this embodiment, the signature generation module is used to generate a complete electronic receipt, wherein an RSA key pair of the electronic receipt to be signed is constructed, and the electronic receipt to be signed is processed by the SHA-256 hash algorithm to generate a data digest, the hash value is signed by the private key, and a complete electronic receipt with an electronic signature is generated, and then the complete electronic receipt and the signature are stored together;

[0034] In this embodiment, the supervision verification module is used to verify the data integrity of the electronic invoice, wherein the complete electronic invoice checks the placeholder empty value and error value of the complete electronic invoice after the electronic signature is generated. When the check is abnormal, the electronic invoice cannot be generated. When verifying the electronic invoice, the public key is used to verify the electronic signature to check whether the invoice data is consistent.

[0035] Furthermore, the regulatory verification module is also used to verify, match and check the electronic invoice format, and generate the electronic invoice format detection result. If the result is abnormal, the blank invoice is re-scanned or uploaded. If the result is successful, the placeholder empty value and error value check are performed. Among them, the invoice format detection includes checking whether the invoice code, date format, amount format, etc. meet the specifications. When the invoice format detection result is successful, the electronic invoice continues to be checked for empty value and error value to ensure that all required items are filled in correctly and there are no error messages.

[0036] It should be noted that the bill supervision module generates a data operation log by obtaining the data changes of the real-time electronic bill, and generates a real-time monitoring report based on the data operation log and sends it to the platform administrator.

[0037] Also, see Figure 2 , an embodiment of the present invention provides an enterprise information management integration method based on big data, comprising the following steps:

[0038] S1. Obtain blank receipt images and business license images by scanning with a scanning device or uploading images, and convert them into electronic receipts and electronic business licenses;

[0039] S2. Use optical character recognition to identify characters in the electronic bill and match the characters with the preset bill type. Automatically classify and store the bill type as a bill template, obtain the bill template, and select and set a placeholder box on the bill template. The placeholders are named according to the business information of the enterprise required for the bill.

[0040] S3. Extract the text part of the electronic bill and the electronic business license as characters through optical character recognition, obtain the characters of the enterprise industrial and commercial information in the electronic business license and replace them with the placeholders on the bill template to generate the electronic bill to be signed;

[0041] S4. Construct the RSA key pair of the electronic receipt to be signed, perform SHA-256 hash algorithm on the electronic receipt to be signed to generate a data digest, sign the hash value with the private key, generate a complete electronic receipt with electronic signature, and then store the complete electronic receipt and signature together;

[0042] S5. Check the placeholder empty value and error value of the complete electronic invoice. If the check is abnormal, the electronic invoice cannot be generated. When verifying the electronic invoice, use the public key to verify the electronic signature to check whether the invoice data is consistent.

[0043] In summary: In the present invention, the information entry module uses scanning equipment or image uploading technology to quickly obtain and convert corporate business information and bill information into electronic format, thereby improving the accuracy and speed of data entry. The bill preset module automatically identifies and classifies electronic bills through optical character recognition technology, sets standardized bill templates, and intelligently sets placeholders on the templates to facilitate subsequent data replacement.

[0044] The bill processing module automatically fills in and generates electronic bills to be signed based on the company's industrial and commercial information, and uses RSA encryption technology to generate a secure electronic signature to cover the electronic bill to ensure the legality and integrity of the electronic bill.
