The authenticity detection configuration module can configure the length of metadata, the data type of metadata items and the like according to the file of the government affair service item electronic file filing specification. The authenticity detection configuration module comprises a metadata authenticity configuration unit.

The method comprises the steps of detecting the length of a metadata item or a self-defined metadata item, configuring a detection rule for the length of the data item on the metadata item of an electronic file in a database or an information packet of an electronic file system, namely configuring the length of metadata of the file, selecting the metadata needing to be detected from a metadata management unit in the setting of the length of the metadata, and inputting the length of a character string required by detection on the metadata. Such as 18-bit data configured with a uniform social credit code in the metadata.

After the business system files the electronic file, the electronic file analyzes the electronic file of the electronic file through an electronic file analyzing unit of the authenticity detection module, and the metadata in the electronic file is captured by means of identification, key field reading and the like, so that the metadata of the electronic file is obtained, and then the metadata is compared with the business certificate storage module for verification. And after the verification is passed, the authenticity detection module calls a metadata length configuration rule of the metadata authenticity configuration unit to check whether the data of the unified social credit code meets 18 bits, if so, the item is determined to be passed, and if not, the item is determined to be failed. Similarly, for the mobile phone number, the identity card, the user-defined metadata and the like, the corresponding length rule can be used for verification.

The configuration of data types and formats of electronic file metadata items in the database requires the configuration of type detection rules, and after the metadata is selected from the metadata management unit, the type of each item of metadata is selected.

After the verification is passed, the authenticity detection unit calls the metadata item type and the format configuration rule of the metadata authenticity configuration unit to check the type of the field, and the verification is passed if the type of the field is in accordance with the configuration rule.

And detecting and configuring the value range of the metadata item of the electronic file in the database or the information package, and inputting the starting value and the ending value of the item after adding the metadata field. 1900 to 2022 can be input if the year of filing. After the business system files the electronic file, the electronic file analyzes the electronic file of the electronic file through an electronic file analyzing unit of the authenticity detection module, metadata in the electronic file is captured by means of identification, key field reading and the like, so that the metadata of the electronic file is obtained, and then the metadata is compared with the business evidence storage module for verification. After the verification is passed, the authenticity detection unit can call a metadata item value range detection rule of the metadata authenticity configuration unit to detect whether the value range accords with the metadata field. If the analyzed filing year field in the electronic file is 2023, the authenticity detection unit will automatically determine that the data does not conform to the actual filing specification, and the detection result is failed.

Detecting whether the data value of the metadata item of the electronic file in the database contains special characters, selecting corresponding detection metadata from the metadata management unit, and checking whether to detect the special characters, if the authenticity detection unit defaults to! @ # and (): (ii) a Carrying out verification by taking special characters such as < > - >, and the like as verification conditions; wherein, as fields not in the regular character and fields not in the special character library, the identification can be added into the special character library as the check condition.

And detecting and configuring the electronic file number, the file number and the like in the database or the information package. Referring to fig. 4, a diagram illustrating the setting of profile number expression in an exemplary embodiment of the present application, a profile generation rule can be set for a single item by calling a metadata field in a metadata management unit and an item management unit. In selecting fields, after selecting a field, the selected field may be spliced into a regular expression. And similarly, data verification is performed after filing, and then verification is performed according to rules. The electronic file analyzing unit can splice and assemble the metadata fields analyzed by the electronic file according to rules, and then compares the metadata fields with the metadata of the actual incoming file number, if the comparison is inconsistent, the file generation error is indicated, and the detection is failed.

Whether the data value of the electronic file metadata item in the database or the information package is in a reasonable range or not is detected and configured, and the length, the value range and the data reasonability of metadata can be checked according to the type of the archived file after the metadata is added in a metadata authenticity configuration unit. And selecting different checking rules for different metadata, such as a regular checking for selecting a unified social credit code for the unified social credit code, wherein the metadata detects the data reasonableness in addition to the detection of the length, the value range and the like, such as/[ 0-9A-HJ-NPQRTEWY ] {2} \ d {6} [ 0-9A-HJ-NPQRTEWXY ] {10 }/checking mode. The metadata detected by the item is more in line with the business requirements of the real archive.

After the metadata authenticity detection is completed, the four-characteristic detection reporting unit lists the passing and failing conditions of each item according to the detection result of each item, records the detection time, and counts the information of the detected items, the failing items and the like.
