Conventional USB flash drive cannot meet user's demand to the unicity function of data storage.Along with enterprise secret is revealed, customer data is stolen and network on the taking place frequently of the case such as all kinds of " door events ", the security of data has also been pushed to the teeth of the storm thereupon, consumer improves rapidly the protection consciousness of data message.Individual privacy in flash disk and the safety of classified papers receive people's concern day by day.In order to protect better the safety of information in user's USB flash disk, be badly in need of developing the encryption USB memory disc with display screen.
Summary of the invention
The object of the invention is to solve and prevent that USB flash disk from surprisingly losing or accessed the data disclosure risk of bringing and a kind of secret USB memory disc and the method for controlling security thereof with display screen with cipher protection function providing by illegal possessor; simultaneously in order to prevent that user from being peeped in the time that computor-keyboard is inputted password; in USB flash disk external body, display screen and control are set, input password and identifying code by miniature display screen and control.
The object of the present invention is achieved like this:
With a secret USB memory disc for display screen, it is characterized in that: comprising:
Flash encryption chip, carries out safe encryption memory function for realizing to user profile, and the data of storage are to leave in Flash with the form of ciphertext, key produces at random, is placed on chip internal, even if obtain the data in Flash, there is no key, is equally the mess code of failing to understand;
With the safety chip of USB interface, be used for carrying out data transmission between Flash encryption chip, simultaneously also for user is verified by the PIN code of button and display screen input, this PIN code passes to safety chip by gsm module, if success produces an identifying code, sends to gsm module, if mistake, points out user to re-enter, safety chip is compared to the verification code information of user's input, correctly normally starts USB memory disc, otherwise prompting user re-enters;
Gsm module, for sending to user mobile phone by the identifying code receiving from safety chip.
Safety chip is further used for that user is set inputs the thresholding of security pin code number of times, if the number of times of authentication error exceedes described thresholding, carries out mistake and processes.
Gsm module uses note form that identifying code is sent to user mobile phone.
Described identifying code is random number.
A kind of secret USB memory disc with display screen, comprise Flash encryption chip, memory interface, safety chip, USB interface, gsm module, button and display screen, it is characterized in that: wherein Flash encryption chip is connected with safety chip by memory interface, gsm module is connected and carries out data interaction respectively with between safety chip and button and display screen by I/O port, and USB interface is connected with safety chip by 4 edge joint lines.
The button of the control of described secret USB memory disc is divided into up and down and five operating keys of OK, has the key of oneself under each button, and each key is connected with English module with the digital module in safety chip, and digital module comprises 0-9 totally ten arabic numeral; English module comprises capitalization A-Z totally 26 English alphabets.
A method of controlling security for secret USB memory disc with display screen, is characterized in that:
Step 1, when described USB memory disc access terminal equipment, system can point out user to input security pin code, and user has inputted and has waited for;
Step 2, verifies the PIN code of user's input, if success produces an identifying code, described identifying code is sent on user mobile phone, if mistake points out user to re-enter;
Step 3, sends to the identifying code of mobile phone and input validation code information in system described in user checks;
Step 4, contrasts the verification code information of user's input, correctly normally starts USB memory disc; Otherwise prompting user re-enters.
In step 2, user be set input the thresholding of security pin code number of times, if the number of times of authentication error exceedes described thresholding, carry out mistake and process.
In step 2, use note form that identifying code is sent to user mobile phone.
Described identifying code is random number.
Feature of the present invention and good effect are as follows: add the operation of user to miniature control by rigorous password and identifying code protection, ensured the use safety of individual USB flash disk from inside and outside two aspects.Encryption USB memory disc with display screen and control not only possesses the memory function of common U disk, but also has the cipher protection function of USB flash disk.Its characteristic is that external miniature display screen and the control of its novelty operate password, can guarantee that user's password in the time of input password is not easy to be peeped, and operates more careful, safer with respect to traditional at computor-keyboard; Its built-in password and identifying code protection simultaneously verified USB flash disk user identity, thus the safety of guarantee USB flash disk information.
