The utility model has a plurality of protective functions, which makes the stored data more secure, convenient and faster.
Description
Technical field
The utility model belongs to the hardware of computer system, specially refers to a kind of memory storage that has fingerprint identification function.
Background technology
Along with development of electronic technology, the widespread use of computing machine, the information security of computing machine is maintained secrecy and more and more to be come into one's own, even move as the temporary transient of file, also usually needs a kind of reliable device to come data are carried out safekeeping in order to ensure the safety of file.At present, fingerprint identification technology has obtained extensive usefulness, for example: the Chinese patent publication number be open day of CN1314655 for September 26 calendar year 2001 denomination of invention be finger print hard disc, this application case discloses a kind of memory storage with Fingerprint Identification Unit and hard disk combination, utilize fingerprint to carry out identity and debate knowledge, having only me just can enter storage space operates, compared with modes such as traditional employing password or other keys, make the data of storage safer, but, this invention only depends on fingerprint identification technology still must unavoidably steal storage chip separately, and is solded on other storage chip control panel, steals the possibility of decoding.In addition, traditional USB flash disk, cap separates with housing, and cap is easy to lose, and uses also very inconvenient.
The utility model content
The purpose of this utility model is exactly the deficiency that prior art is existed, propose a kind of except that having finger print identification function, The data dynamic key encryption and decryption to storage splits storage with the bit level simultaneously, key separates with the ciphertext algorithm, makes it have the finger print safety storage U disk of multilayer defencive function;
Another purpose of the present utility model is to adopt fingerprint to drive built-in and a change page or leaf technology, makes authorized user enter usage space quickly and easily;
Another purpose of the present utility model is without the shell cap, the USB interface and the USB flash disk housing of USB flash disk can be placed in the groove of USB flash disk valve jacket, to avoid losing the inconvenience that brings to the user because of the shell cap.
The purpose of this utility model is achieved through the following technical solutions:
This utility model mainly comprises USB flash disk housing and the USB interface that is connected thereof, and controller, fingerprint sensor, memory storage are housed on the mainboard in the USB flash disk housing, and controller links to each other with USB interface, fingerprint sensor, memory storage by circuit respectively;
Wherein, USB interface: peg graft with the computing machine USB interface, in order to exchange message and accept operational order; Fingerprint sensor: mainly be to gather individual fingerprint characteristic information, be used for identification of fingerprint; Controller: mainly be the work of coordinating fingerprint sensor, memory storage and computing machine, realize safe and orderly information is handled, and the data on the usb bus are added, decipher; Memory storage: the method by reset file allocation table and self-built file memory format preferably becomes the memory storage scribing 3 districts, i.e. main program area, hidden area, private area with 2-4 district of memory storage scribing; Main program area: mainly deposit the fingerprint recognition program, and adopt fingerprint to drive built-in and a change page or leaf technology, make authorized user can just enter user's usage space more efficiently; The hidden area: the user is invisible, is mainly used to deposit the information of fingerprint feature point, and for cooperating network security to deposit capsule information such as pkI, program can be moved, but can not be replicated; Private area: be the space that authorized user uses, in the private area that authorized user uses, store and all will pass through the fingerprint recognition program when reading file, and through becoming a page technology, enter the authorized user usage space, simultaneously the secret key encryption and the deciphering that also will go out through the algorithm computation in controller; During data encryption, encryption key generates at random according to each finger print identifying unique point, be not kept in the flash, during deciphering according to the unique point code and the encrypt file condition code computing generating solution decryption key of storage; In addition, for guaranteeing the safety of data, can adopt encryption and bit level to split storage simultaneously to the data that deposit in, be about to each byte and split according to bit, the data after the fractionation are by specific hardware or software algorithm, and promptly zones of different or the plate that deposits storage chip in according to different address informations and file identification carries in the chip, and self-built new file allocation table, preserve the compression back, when reading numeral this algorithm deciphering back and decompress files allocation table is carried among the RAM to plate, realizes writing and reading of data.Therefore use the bit level to split algorithm, file is present on flash and the controller chip stored space, and only the data of flash inside are incomplete, and therefore adopting the reverse decoding of method of decompiling is invalid basically.As reading of data, also must carry out fingerprint authentication, and split the inverse operation deciphering of algorithm, thereby prevent that effectively stealing flash separately carries out the means that the USB flash disk internal data is obtained through the bit level.
The USB interface of this utility model USB flash disk is connected with the USB flash disk valve jacket by axle with the USB flash disk housing, USB interface and USB flash disk housing can be folded and placed in the USB flash disk housing groove, without the shell cap, can avoid the inconvenience that brings to the user of losing because of the shell cap.
The fingerprint sensor of this utility model, the push type capacitive transducer that adopts the semiconductor die chip technology to make; Memory storage is to adopt NAND type Flash storer; Controller is to adopt the microprocessor of 16 bit, and built-inly adds, decipher to patrol and make a bow with hands clasped, and supports NAND flash and USB high-speed communication, and realization adds in real time, decryption acts.
Because this utility model adopted fingerprint identification technology, make crack and usurp cryptographic means become impossible.Split the algorithm stores data to depositing The data dynamic key encryption and decryption in the Flash and bit level in, effectively prevented to steal the flash chip separately and be solded into the means of stealing the USB flash disk internal data on other the flash chip controls plate.Storage space is carried out scribing, help integrated management, and the program in the hidden area can not be replicated storage space and controller inner space.The data that authorized user is stored in the private area are safer, and simultaneously owing to adopt and become page or leaf technology and fingerprint and drive built-inly, USB interface and USB flash disk housing be collapsible to be placed in the groove of USB flash disk valve jacket, and it is more convenient that the user is used.
