Abstract

The invention discloses an office system for improving data security; the office system comprises a local area network, a removable storage device, a universal serial bus (USB) encryption and decryption bridge and a USB key device, wherein the local area network comprises a plurality of computers; one end of the USB encryption and decryption bridge is connected with a south bridge chip on a computer mainboard, and the other end of the USB encryption and decryption bridge is taken as a main interface for an exposed USB storage device; the USB encryption and decryption bridge comprises a USB encryption and decryption bridge function management module, wherein the USB encryption and decryption bridge function management module is located between the USB encryption and decryption bridge and the USB key device and used for responding an instruction of the USB key device, thereby configuring functions of the USB encryption and decryption bridge; the USB encryption and decryption bridge further comprises a first USB slave interface module, a USB main interface module, a data storage area, a first encryption and decryption module, a first flash storage module and a USB data transmission management module; and the USB key device further comprises a second USB slave interface module, a second encryption and decryption module and a second flash storage module. According to the office system, a working area can be set freely, thereby facilitating authority management efficiency and effectively preventing leakage of the data in the working area.

Description

[0001] The original application number is 201110020320X, the application date is January 18, 2011, and the title of the invention is: office system for improving data security. technical field [0002] The invention relates to an office system for improving data security, which belongs to the application field of safe storage. Background technique [0003] At present, USB storage devices are the most widely used mobile storage devices, including U disks and mobile hard disks. More and more enterprises and institutions use USB storage devices as a tool for exchanging information on a daily basis. In the process of using them, there are two risks: on the one hand, the important business data and internal information stored on the internal computers of enterprises and institutions may be Leakage through the USB port; on the other hand, similar information on the USB storage device may also be leaked when the device is lost. Once these data are leaked, it will cause significant...
