Forget to pull out USB flash disk after using USB flash disk, so as to cause USB flash disk to be lost, especially surfed the Net in public computer or Internet bar.Cause
This, a kind of necessary USB flash disk that can encrypt the anti-loss of special and can of design.
The Application No. applied at present on rarely seen school colleague teacher Liu Qundi of report of anti-loss USB flash disk
201620299008.7《A kind of anti-loss USB flash disk》Utility model patent, and the application is improved on the basis of the patent
Upgrading.
The content of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model, which is to provide one kind, can carry out that specially to enjoy encryption special
The USB flash disk of the anti-loss of and can.
In order to realize above-mentioned technical purpose, the utility model embodiment provides a kind of USB flash disk, including USB flash disk body and USB flash disk connect
Mouthful and, the USB flash disk body is provided with memory cell and control unit, the USB flash disk interface and memory cell respectively with control unit
Connect, encrypting fingerprint module is additionally provided with the USB flash disk body, the encrypting fingerprint module includes fingerprint reader, fingerprint is deposited
Storage unit and fingerprint identification unit；The fingerprint identification unit is connected with control unit, and the finger reading unit and fingerprint are deposited
Storage unit is connected with fingerprint identification unit respectively.
Preferably, alarm module is additionally provided with the USB flash disk body, the alarm unit includes battery, LED and report
Alert device, the battery, LED and alarm are connected with control unit.
Preferably, the USB flash disk interface is USB interface.
Preferably, the USB flash disk also includes key-press module, and the key-press module is connected with control unit, the key-press module
For setting USB flash disk user fingerprints information and closing storage battery power supply.
Compared with prior art, the beneficial effect of technical solutions of the utility model is, USB flash disk described in the utility model can be real
Existing encrypting fingerprint, realizes that special messenger is special, even if someone borrow can also with other people can not fingerprint decryption borrowed for interface refusal, both
Do not seem stingy, and can is refused other people and borrowed well；Secondly because be additionally arranged encrypting fingerprint, even if they pick up USB flash disk also without
Method obtains internal data easily, and data are played a protective role；Last USB flash disk described in the utility model is additionally provided with alarm module, energy
After computer shutdown, triggering USB flash disk sends alarm, reminds user to pull out away USB flash disk.
Brief description of the drawings
Fig. 1 is the modular unit connection figure of USB flash disk described in the utility model embodiment.
In figure：1 control unit, 2 interface units, 3 memory cell, 4 fingerprint identification units, 5 fingerprint readers, 6 fingerprints
Memory cell, 7LED lamps, 8 batteries, 9 alarms, 10 key-press modules.
Embodiment
In order to become apparent from clear statement the technical solution of the utility model, have below in conjunction with the accompanying drawings to the utility model body
Embodiment is described in detail.
Referring to Fig. 1, present embodiments provide a kind of USB flash disk, including USB flash disk body and USB flash disk interface and, the USB flash disk body
Provided with memory cell and control unit, the USB flash disk interface and memory cell are connected with control unit respectively, in the USB flash disk body
Encrypting fingerprint module is additionally provided with, the encrypting fingerprint module includes fingerprint reader, fingerprint memory cell and fingerprint recognition
Unit；The fingerprint identification unit is connected with control unit, and the finger reading unit and fingerprint memory cell are known with fingerprint respectively
Other unit connection.Wherein USB flash disk interface unit is connected with computer, and rear USB flash disk is powered in connection, USB flash disk control unit triggering fingerprint recognition
Module carries out finger-mark check, after the fingerprint reader in fingerprint identification module reads the finger print information of user, by user fingerprints
For feedback of the information to fingerprint identification unit, fingerprint identification unit transfers the fingerprint letter of USB flash disk owner registration out of fingerprint memory cell again
Breath is compared, and after the fingerprint comparison of the fingerprint of reading and storage is correct, signal is transmitted to control unit by fingerprint identification unit, is made
Memory cell is connected with interface unit；If the fingerprint contrast failure of fingerprint identification module, memory cell can not with interface unit
Carry out data exchange.
In order to prevent from forgetting after computer is using complete shutdown pulling out away USB flash disk, the present embodiment has been carried out further for above-mentioned USB flash disk
Improvement, also have additional alarm module in the USB flash disk body, the alarm unit includes battery, LED and alarm,
The battery, LED and alarm are connected with control unit, and after USB flash disk connects computer, it is filled wherein battery
Electricity, until battery capacity is full of, and LED continues light yellow, if computer occurs shutting down or after USB flash disk pulls out, control unit excites
Battery is powered, and now control unit control LED progress is glittering, while control unit control alarm sends buzzing
Sound.
Preferably, the USB flash disk interface is USB interface.
The USB flash disk also includes key-press module, and the key-press module is connected with control unit, and the key-press module is used to set
USB flash disk user fingerprints information and closing storage battery power supply.Key-press module is connected with control unit, and its function is to set fingerprint
Finger print information in memory module, and trigger battery in power-off after computer shutdown or USB flash disk pull away computer for USB flash disk and supply
Electricity is artificially closed to battery, and long-press key-press module represents to reset the finger print information in fingerprint memory cell, if
Short-press key-press module during storage battery power supply, then it represents that storage battery power supply is closed, if when battery is not powered, short-press key-press module
USB flash disk does not produce any action.
The operation principle of USB flash disk described in the present embodiment is, when using USB flash disk for the first time, USB flash disk interface to be connected with computer, at USB flash disk
