Intelligent active anti-virus U disk based on partition authentication and anti-virus method of U disk

Abstract

The invention discloses an intelligent active anti-virus U disk based on partition authentication. The U disk comprises a power supply, a main control chip with a universal serial bus (USB) interface, a memory chip connected with the main control chip, and a central processing unit (CPU), wherein the CPU is connected with the main control chip and comprises an identity authentication module; and the memory chip comprises an encrypted partition and an open partition. By the U disk and an anti-virus method thereof, a plurality of identity authentication processes are set, and data can be self-destructed after identity authentication error times reaches preset times; and in addition, the U disk cannot be used in an unauthorized computer, all operation logs are archived and recorded, and the data is encrypted and stored. By the anti-virus method, the confidentiality of the U disk can be obviously enhanced, a data self-destruction program can be immediately triggered after the U disk is used by a user who does not know an identity authentication password, and the data is prevented from being stolen to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of USB storage, in particular to an intelligent active epidemic prevention USB disk based on area authentication and an epidemic prevention method thereof. technical background [0002] As an external device of the computer, the USB flash drive has become an indispensable and important part of the computer system, and has been widely used for its portability, ease of use, large capacity and relative safety. However, people also have great concerns about this convenient data storage and exchange method, especially for individual users and enterprise users who have data confidentiality requirements, the security of U disk devices has become an important indicator of this product. For the party, government, government agencies and national core enterprises, the weak data security brought about by the convenience of ordinary U disk devices is a fatal flaw. [0003] The general U disk does not have the function ...

AI Technical Summary

Problems solved by technology

The encrypted USB flash drives sold on the market usually rely on the encrypted operation interface provided by the host operating system. Although certain protection is provided for the data in the USB flash drive, these data can still be accessed by any host, and It is even easier to obtain the password for user authentication after the host is infected by a virus / trojan horse; the encrypted U disk system with high confidentiality may directly replace the standard system underlying driver, and the protection of the data content in the U disk also depends on The software on the host side and the firmware of the U disk itself, but the U disk itself is still completely in a passive state, and can also be "physically accessed" at will, and often cannot meet specific needs in many occasions
