Abstract

The invention provides a traceless access controlling method and a device based on protection of a visual magnetic disc. The traceless access controlling method and the device based on protection of the visual magnetic disc are characterized in that a usbkey is used for setting up a visual magnetic disc in a system of a user terminal. A safety gateway device with a safety plug-in board is arranged between the user terminal and a web server. The usbkey is used for identifying a user identity by accessing a classified web system. The visual magnetic disc is mounted on the safety plug-in board to set up a visual accessing space. Files in the visual accessing space are oriented again to the visual magnetic disc. According to the traceless access controlling method and the device based on protection of the visual magnetic disc, only a user is allowed to access the files in the visual magnetic disc. Other progresses in the system are forbidden from accessing user files in the visual magnetic disc so that safety of the files in a transmission process is ensured and safety of local files of the user is ensured.

Description

technical field

[0001] The invention relates to the technical field of network security, in particular to a method and device for controlling a client's traceless access.

[0002] Background technique

[0003] When a user accesses the web system through a browser, the browser not only saves the browsing history locally, but also saves data such as temporary files and input URL records in the local temporary directory. Even if the user clears all cache files and access history records when exiting the browser, illegal users can still restore the cleared files and records through various data recovery tools. At the same time, illegal users can also steal the user's cache files through tools such as Trojan horses, causing security risks of leaking secrets.

[0004] When a user accesses a confidential system through a browser, the data packet is encrypted in plain text during network transmission. When users download and upload files, there is a risk of being eavesdropped and...

Examples

Embodiment Construction

[0041] Such as figure 1 , figure 2As shown, a non-trace access device based on virtual disk protection includes a client terminal 1 and a web server 4, and the client terminal 1 and the web server 4 are interactively connected through a security gateway device 3; the client terminal 1 is provided with USB interface, described USB interface is plugged with usbkey 2. Described usbkey 2 comprises single-chip microcomputer 2-1, and described single-chip microcomputer 2-1 is interactively connected with memory module 2-2, safety protection module respectively, and described single-chip microcomputer 2-1 carries out interactive connection with security gateway equipment 3. The safety protection module comprises the file filtering driver module 2-3 that prevents the application program or process that visits by usbkey from saving, the copy operation and its cache directory is forced to be redirected to the orientation module 2-4 in the memory module 2-2; The file filtering driver ...
