In this embodiment, the preset time period may be one minute or one hour, which is not limited in this embodiment, and to improve the monitoring efficiency, thirty minutes is taken as an example, the first file list information on the preset service platform is imported from the preset service platform every thirty minutes, where the first file list information includes at least one of file name information and file path information, for example, the item a evaluation report and the corresponding file path thereof are computer 110> DATA (D:) > item a, the preset service platform may be a file auditing management system, the file auditing management system manages and controls files on the platform according to preset rules, and may also be an off-site counter transaction core subsystem, for example, an OTC system (over-the-counter market), where a file list that needs to be imported for clearing every day is stored in the OTC system, in this embodiment, an OTC is taken as an example for explanation, it should be emphasized that, in order to further ensure the privacy and security of the first file list information, the first file list information may also be stored in a node of a block chain.
It can be understood that in the OTC system, a file list to be imported for clearing every day is stored, so that the file list to be imported is queried by docking the OTC system database according to the configured data table query script, database name, user and password.
Step S20, encrypt each file in the first file list information to obtain first label information corresponding to each file in the first file list information.
It should be noted that the first tag information may be an MD5(Message-Digest Algorithm5, information summarization Algorithm 5) value, and may also have unique tag information in other forms, which is not limited in this embodiment, and in this embodiment, an MD5 value is taken as an example for description.
In a specific implementation, a preset rule is adopted to encrypt the first file list information to obtain tag information corresponding to each file in the first file list information, where an encryption manner may be obtained by encrypting a file name in the first file list information, or may be obtained by encrypting a file path in the file list, which is not limited in this embodiment, and the example of encrypting the file name is described in this embodiment.
Step S30, obtaining second file list information recorded in the preset service platform in a previous time period of the first time period, and reading second label information corresponding to each file in the second file list information.
