USB flash disk virus isolator and working method thereof

Abstract

The invention relates to the technical field of USB flash disk virus isolation, in particular to a USB flash disk virus isolator and a working method thereof.The USB flash disk virus isolator comprises a main control chip used for strictly controlling and checking data access; the storage module is used for caching the isolated virus files; the network interface module is accessed to a local areanetwork by adopting an international general network protocol; the USB interface module is used for being externally connected with a USB flash disk; the display module is used for visually displayingthe equipment operation state; the storage module, the network interface module, the USB interface module and the display module are respectively connected with the main control chip through corresponding lines; uSB flash disk data is filtered and screened through a built-in system program of the main control chip; the system program automatically detects and identifies the safety file of the white list and the virus file of the black list, the safety content on the white list is allowed to be connected with the PC through the local area network to be read and written, and once the system program scans the content on the black list, the corresponding content is immediately isolated and hidden, so that virus spreading caused by misoperation of a client is avoided.

Description

technical field [0001] The invention relates to the technical field of U disk virus isolation, in particular to a U disk virus isolator and a working method thereof. Background technique [0002] According to relevant data, many viruses are currently transmitted through mobile devices. In particular, the frequency of transmission through the U disk is relatively high. In particular, there will be a situation where the U disk scanning and killing is quarantined. This is because many people have not realized the importance of U disk antivirus. As a result, a lot of information and data were lost and lost, and even made the company fall into a situation where it was difficult to operate. [0003] The existing authorized patent (notification number: CN208172797U, announcement date: 2018-11-30) discloses a U disk isolator, the U disk isolator includes: read and write communication module, the read and write communication module includes: USB interface module, used for connect...

It even caused a lot of missing information and data, and even made the company fall into a situation where it is difficult to operate.

[0003] The existing authorized patent (notification number: CN208172797U, announcement date: 2018-11-30) discloses a U disk isolator, the U disk isolator includes: read and write communication module, the read and write communication module includes: USB interface module, used for connecting USB device; And network interface module, used for connecting host computer, and master controller, used for reading the hardware ID information of described USB device, and judge the described USB device of described reading Whether the hardware ID information is consistent with the hardware ID information of any one of the USB devices that allow access to the host computer, if the two are consistent, then control the USB device to be recognized by the host computer; The hardware ID information of the USB device connected to the host controls whether the USB device is recognized by the host, thereby realizing effective filtering of the USB device, thereby preventing the spread of virus files and improving data security; but the U disk disclosed in this patent The isolator mainly uses the hardware ID information to identify and match the host, so as to prevent unknown U disks from carrying virus infections, which has relatively large limitations and cannot fundamentally isolate the spread of viruses.
