step S11, after detecting that the mobile storage device is accessed, the file transmission device scans the mobile storage device to acquire virus files in the mobile storage device and file directory tables corresponding to all files in the mobile storage device;
and step S12, marking the catalogs corresponding to the virus files in the file catalogs to obtain a safe file catalogs.
After detecting that the mobile storage device is accessed, scanning the mobile storage device, wherein the scanning comprises anti-virus scanning and file directory tree structure scanning, the anti-virus scanning is to scan files with viruses or illegal files in the mobile storage device, specifically, the file transmission device scans the mobile storage device to obtain the detection report list, and then obtains the files with viruses or illegal files in the mobile storage device according to the detection report list. The file directory tree structure scanning is to scan all files in the mobile storage device, and it can be understood that after the antivirus scanning and the file directory tree structure scanning are performed on the mobile storage device, files with viruses in the mobile storage device and file directory tables corresponding to the files in the mobile storage device can be obtained, and the file directory tables record directories of all files in the mobile storage device.
It can be understood that after the file with virus in the mobile storage device and the file directory table corresponding to each file in the mobile storage device are obtained, each directory corresponding to the file with virus or illegal file is marked in the file directory table, so that the file directory table corresponding to the file with virus or illegal file cannot be accessed, and a secure file directory table is obtained, that is, only the security file which is not marked in the secure file directory table can be accessed. The secure file directory table also records the directories of all files in the mobile storage device, but only the files corresponding to the untagged file directories can be accessed. For example: when the mapping relation table between the secure file directory table and each secure file is generated, the marked file directory does not generate a mapping relation, i.e. the marked file directory does not have a corresponding file address.
In this embodiment, after detecting that the mobile storage device is accessed, the mobile storage device is scanned to obtain virus files in the mobile storage device and file directory tables corresponding to all files in the mobile storage device, and in the file directory tables, directories corresponding to all the virus files are marked to obtain a secure file directory table, so that the secure file directory table is obtained according to the virus files and the file directory table, the operation is simple and safe, and security threat is not generated to the data access device.

The scanning comprises anti-virus scanning and file directory tree structure scanning, a detection report list is obtained according to the anti-virus scanning, all security files in the mobile storage device are recorded in the detection report list, file directory tables of all the files in the mobile storage device are obtained according to the file directory tree structure, and it is understood that the security file directory tables can be obtained by marking file directories which are not security files in the file directory tables. Wherein, the secure file directory table also records the directories of all files in the mobile storage device, but only the files corresponding to the untagged file directory can be accessed. For example: when the mapping relation table between the secure file directory table and each secure file is generated, the marked file directory does not generate a mapping relation, i.e. the marked file directory does not have a corresponding file address.
In this embodiment, after detecting that the mobile storage device is accessed, the mobile storage device is scanned to obtain the security files in the mobile storage device and the file directory tables corresponding to the files in the mobile storage device, and then the directories corresponding to the security files are obtained in the file directory tables to obtain the security file directory tables, so that the security file directory tables are obtained according to the security files and the file directory tables, and the operation is simple and convenient.

After the mobile storage device is scanned to determine the secure file directory table, the device identifier of the mobile storage device may be acquired first, where the device identifier is used to identify whether the mobile storage device currently accessed is the mobile storage device accessed last time. It can be understood that when the device identifier is associated with a preset mapping relationship table, and the scanned secure file directory table is inconsistent with the secure directory table in the preset mapping relationship table, the step of generating the mapping relationship table between the secure file directory table and each secure file is performed. Optionally, when the device identifier is associated with a preset mapping relation table, and the scanned secure file directory table is consistent with the secure directory table in the preset mapping relation table, the stored mapping relation table is directly called for the data access device to use. Optionally, when the device identifier association does not have a preset mapping relation table, the step of generating the mapping relation table between the secure file directory table and each secure file is executed.
In this embodiment, after the mobile storage device is scanned to determine the secure file directory table, the device identifier of the mobile storage device may be first obtained, and when a preset mapping relation table is associated with the device identifier and the scanned secure file directory table is inconsistent with the secure file directory table in the preset mapping relation table, the step of generating the mapping relation table between the secure file directory table and each secure file is executed, so that the mobile storage device that is currently accessed is first identified, and the mapping relation table between the secure file directory table and each secure file is regenerated, which is easy and convenient to operate.
