USBKey one kind of Mobile Data Based Security

The present invention discloses a mobile data application USBKey security system and a method based on the present invention, by the network security management data distribution USBKey machine, the need to carry data files stored in a mobile USBKey hidden partition, and the data through USBKey authentication information using the read-only partition for personnel authentication, security control for mobile usage behavior data files by running the control program startup drive partition, and the entire course of conduct safety audits, need to be used up after USBKey the next time write-off and recovery for distribution. The present invention, by the authentication data file transparent encryption and decryption can be prevented after USBKey loss or outgoing service by data recovery data information leakage caused; through a system message hook and a disk control program prevents the user USBKey the data file by copying or Save for the other operation, the data stored in other media.
