The components can also reduce the amount of data entered by the user to reduce errors in the drafting process, and the generated procurement documents can be electronically signed, which greatly improves the efficiency, quality and security of procurement document drafting.
[0107] 2. Automatically obtain a large number of historical procurement documents from the database through ETL tools, identify the file content of each historical procurement document through OCR technology, and parse the content of each file through a pre-trained large language model to obtain the corresponding file structure. That is, the file structure is obtained from a large number of historical procurement documents through a large language model. This can not only ensure the accuracy of file structure acquisition, but also ensure the comprehensiveness of file structure acquisition, thereby ensuring the quality of subsequent component creation and avoiding the loss of related components that affect the generation of procurement documents.
[0108] 3. By setting the procurement document draft request to carry the account number, password, first timestamp and hash value, the integrity can be checked through the hash value, the timeliness can be checked through the first timestamp, and the legitimacy can be checked through the account number and password. The file template configuration panel will be displayed through the visual interface only after the verification is passed, preventing illegal personnel from arbitrarily configuring file templates, thereby greatly improving the security of procurement document generation.
[0109] 4. By setting data interception rules and a pair of public and private keys, the basic data of the signature is intercepted from the procurement document based on the data interception rules, the current second timestamp is obtained, MAC calculation is performed on the basic data of the signature and the second timestamp to obtain the MAC value, the basic data of the signature, the second timestamp and the MAC value are signed by the private key to obtain the signature data, the basic data of the signature, the second timestamp, the MAC value and the signature data are encrypted by the 3DES algorithm to obtain the encrypted data, and the encrypted data is converted into a signature QR code by the QR code generator; the encrypted data is obtained by scanning the signature QR code to prevent the relevant data from being stolen in plain text. After the encrypted data is decrypted by the 3DES algorithm, the signature data is verified by the public key, and the integrity is checked by the MAC value, and the timeliness is checked by the second timestamp. Multiple security measures have been taken before and after, which greatly improves the difficulty of forging the signature QR code, thereby greatly improving the security of the procurement document.
