Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Among the figure: fingerprint sensor 1; Memory modules 2; Controller 3; Storage hard disk 4; Expansion slot 5; Hardware enciphering and deciphering engine 6; Memory interface 7; Memory interface 8; External interface 9; Memory modules public area 21; Memory modules closed security zone 22; Memory modules hidden area 23; Terminal system 10.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The encrypting fingerprint portable memory is made of following structure: storage hard disk 4 is used for data message is stored; Memory modules 2 is used for application storing, the data that need protection, finger print data, hardware enciphering and deciphering engine key, user basic information; Fingerprint sensor 1 according to the control of controller 3, grasps real-time finger print data, and transmits the finger print data that is grasped to controller 3; Controller 3, the data that are used between control store device, memory modules 2, fingerprint sensor 1 and the terminal system 10 transmit; Hardware enciphering and deciphering engine 6 is used to receive the key that controller 3 transmits, and the data that read and store is decrypted and encrypts.
Described storage hard disk 4 is connected to controller 3 by memory interface 7 after being connected to hardware enciphering and deciphering engine 6 by expansion slot 5 again; Memory modules 2 is connected to controller 3 by memory interface 8; Fingerprint sensor 1 is connected to controller 3 by winding displacement; The external interface 9 of encrypting fingerprint portable memory is USB (universal serial bus) (USB interface) or IEEE1394 interface, and described memory interface 7 is an ide interface.
Below the utility model principle of work is described.
Controller with key delivery to the hardware enciphering and deciphering engine; terminal system could see through hardware real-time encryption and decryption engine then; from closed security zone access data to be protected; and carry out encrypt/decrypt in real time; former hiding storage hard disk occurs on terminal system simultaneously; and come access data by hardware real-time encryption and decryption engine; fingerprint sensor is controlled by controller; to grasp real-time finger print data; terminal system compares the real-time finger print data that grasped and previous storage finger print data; so-called previous storage finger print data is to be the finger print data that the owner lands when using for the first time in memory modules, the benchmark of confirming with this finger print data comparison.If correct, then open the storer public area by controller control, use for the user.If incorrect, the person's that deposits the fingerprint in contact method then is provided, ask the other side to return original owner.In the middle of normal the use, original owner can change the finger print information in the flash disk.
Therefore controller coordinate the work between fingerprint sensor, memory modules, hardware enciphering and deciphering engine and the terminal system interface.
This fingerprint portable hard drive can be divided into two steps in the course of the work generally, by the reflection fingerprint authentication, obtains key to the hiding security interval of appointment.Key is write the hardware enciphering and deciphering engine, set up getting in touch between hard disk and the computer.
The memory modules place of safety of appointment is generally in flash memory, join the format software format flash memory of affair in the use standard after, in flash memory, write working procedure, set up between controller and the flash memory 1 pair 1 correspondence contact thus, that is to say, take flash memory separately away and can't obtain the interior correct data of flash memory, and by behind the fingerprint authentication, controller just can switch in the flash memory, just can read inner correct data, and this process need working procedure cooperation is finished, and after the flash memory concealed space obtained key, key was written in the hardware real-time encryption and decryption engine, then set up the contact between hard disk and the computer, in the process afterwards, the data that deposit in have all been passed through the encryption of 3DES standard, extract data and then carry out real time decrypting rapidly.
