Abstract

The invention discloses an office system for preventing data from being divulged. The office system comprises a local area network consisting of a plurality of computers, mobile storage equipment, a universal serial bus (USB) encryption and decryption bridge connector and USB key equipment, wherein one end of the USB encryption and decryption bridge connector is connected with a south bridge chipon a mainboard of the computer and the other end of the USB encryption and decryption bridge connector is used as a main interface of exposed USB storage equipment; the USB encryption and decryption bridge connector further comprises a USB device 1 connected with the south bridge of the computer, a USB host, a data storage area, a first encryption and decryption module, a first flash memory module and a USB data transmission management module; and the USB key equipment further comprises a USB device 2, a second encryption and decryption module and a second flash memory module. In the office system, working areas can be set randomly, rights management efficiency is improved and data in the working areas can be effectively prevented from being divulged.

Description

technical field [0001] The invention relates to an office system for preventing data leakage, which belongs to the application field of safe storage. Background technique [0002] 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 losses to the enterprise or individual. Therefore, data security has become an important part of information security. Using the USB data stream encryption and decryption techn...
