The various protection measures in hardware and in software are utilized in the method in order to prevent the hacker's intruding and protect the safety of the data on the hard disc. In the software, the computer is allowed to start up only the fingerprint authentication is passed or the IC card is utilized. The authentication is done before the computer starts up. In the hardware, the safety of the data on the hardware is protected by use of the encryption/decryption cards and the micro switch on the case. The system at least includes the computer main board, the processor, the north bridge chip, the south chip, the I/O control chip, the keyboard, the card reader, the fingerprint scanner, the hardware, the encryption/decryption card and the case.
Description
Technical field
The present invention is relevant a kind of system and method for guaranteeing computer host safety, particularly utilizes the protected mode of hardware and software simultaneously, to guarantee the safety of host computer.
Background technology
Application along with individual privacy and financial sector, though its convenience is popular, but its security is worrying also, especially will dominate the capital construction of whole application in future network identification and payment system, therefore before being extensive use of, must analyze the safety factor of existing system equipment, otherwise once host computer suffers that the illegal production mode is invaded or hard disk is stolen, will make all data exposures or even distorted.
Protect the identifying procedure of computer host safety traditionally; utilize operating system (OS) to do authentication after being generally start; or in start process, utilize basic input/output system (BIOS) to do authentication; yet these authentication methods are started shooting because of main frame; so can't stop the invasion of hacker (hacker) entirely; therefore the present invention could start shooting after need proposing authentication to pass through, but not just does the invention of authentication after the start.In addition; above-mentioned protected mode only has software mode, if the hard disk that stores data directly is stolen, these with software protection mode will be to make a futile effort; therefore the inventor uses the mode of protection hard disk and data thereof simultaneously again, to reach tight security protection.
Content of the present invention
Fundamental purpose of the present invention is to utilize the protected mode of hardware and software simultaneously, to guarantee the safety of host computer.
Another object of the present invention is to utilize authentication modes such as IC-card and identification of fingerprint, the user need authenticate by after just can make host computer start, but not just do authentication after the start.
Another purpose of the present invention be utilize on an enciphering/deciphering card and the shell microswitch with the protection hardware resources safety.
For achieving the above object, the present invention proposes a kind of system that guarantees computer host safety, and it comprises at least:
One computer motherboard, it comprises at least: a processor (Processor); One north bridge wafer (NorthBridge) is connected with processor, is as the flow management between processor and bus-bar, makes processor one operating system and an identification of fingerprint software be arranged in this storer to the access of devices such as storer; One south bridge wafer (South Bridge) is gone into control wafer with north bridge wafer and output and is connected, and is the bridge as USB interface and peripheral device data input processor; And one output go into control wafer, be connected with the south bridge wafer, this is exported and starts computer after control wafer receives only keyboard input proper password;
One keyboard is gone into control wafer with card reader and output and is connected, and just starts keyboard after this card reader authentication is finished and inputs password for the user;
One card reader, it utilizes operation circuit to be connected to above-mentioned computer motherboard, this card reader can be done authentication to IC-card, if legal user, then start-up control circuit, make the computer normal operation, if remove above-mentioned IC-card before above-mentioned computer normal boot-strap, this card reader starts computer and suspends (suspend) function, stops all and exports into action, and, can't restart above-mentioned computer as not authentication again;
One fingerprint scanner, it is connected with above-mentioned computer motherboard, and this fingerprint scanner is to accept the user to import fingerprint data;
One hard disk, it is connected with above-mentioned computer motherboard, and this hard disk is in order to store data;
One enciphering/deciphering card, it is connected with above-mentioned computer motherboard, this enciphering/deciphering card is to be stored to above-mentioned hard disk more earlier this data is done encryption when storing data after, and read again after when above-mentioned hard disk reads data, earlier this data being done decryption processing, the key of this enciphering/deciphering card is stored on the flash memory of this enciphering/deciphering card; And
One shell, it surrounds above-mentioned computer motherboard, card reader, fingerprint scanner, hard disk and enciphering/deciphering card, this shell comprises a microswitch, can start this microswitch when shell is opened, and removes the key in the flash memory that is stored in above-mentioned enciphering/deciphering card.
Cooperate above-mentioned system, the present invention proposes a kind of method of guaranteeing computer host safety, and it comprises following steps:
A. insert IC-card,, start computer by the IC-card identifying procedure;
B. start the operating system, read fingerprint data from hard disk simultaneously;
C. the user imports fingerprint by fingerprint scanner;
Whether d. identification of fingerprint software is compared above-mentioned fingerprint correct; If not, resumes step (c); If continue next step;
E. login operating system;
F. read/store the data of hard disk by the enciphering/deciphering card; This enciphering/deciphering card is to be stored to above-mentioned hard disk more earlier this data is done encryption when storing data after, and read again after when above-mentioned hard disk reads data, earlier this data being done decryption processing, the key of this enciphering/deciphering card is stored on the flash memory of this enciphering/deciphering card, on the shell microswitch is arranged simultaneously, when shell is opened, can start this microswitch, and remove the key in the flash memory that is stored in above-mentioned enciphering/deciphering card; And
G. check that this IC-card is whether still in card reader; If, but normal shutdown then; If not, then this card reader starts the computer pause function, stops all and exports into action, and display message is notified the user simultaneously.
