By describing the technology contents of technical scheme, structural feature in detail, realizing purpose and effect, below in conjunction with concrete reality
Apply example and coordinate accompanying drawing to be explained in detail.
Fig. 1 to Fig. 2 is referred to, the present embodiment provides a kind of date storage method based on mobile fingerprint, is applied to mobile phone
205th, on server 207, computer 201 and removable storage device 203, specifically, can apply in the system 200 such as Fig. 2
Face.Mobile phone includes mobile phone radio frequency module, fingerprint module and the first near-field communication module, and mobile phone can be with by mobile phone radio frequency module
It is attached with base station, such that it is able to surfing the Net and being connected with server.Removable storage device includes the second near-field communication mould
Block, specifically, removable storage device also includes processing module and memory module, processing module respectively with memory module, second
Near-field communication module and USB interface connection, removable storage device are connected with computer by USB interface, and processing module can be right
Realize that the hardware to memory module data is encrypted, it is to avoid directly read the data of memory module.Removable storage device only has
Second near-field communication module, memory module and processing module, cost can be very low, and head can be made thin little, without the need for power supply, its
Power supply has USB interface to power, and can carry with, easy to carry.
This method comprises the steps：Whether step S101 computer detection removable storage device inserts USB interface, S102
Judge after detecting insertion whether removable storage device is stored with finger print data；Here judgement can be that computer sends an inquiry
Instruction is asked to removable storage device, removable storage device reads memory module, judges whether the finger print data that is stored with, then
By result feedback to the computer, it is to avoid computer directly reads the finger print data and causes the problem that data may reveal.
If not storing finger print data, S103 fingerprints and device password initialization step is entered, step to be initiated is complete
Into laggard checking procedure S104；If being stored with finger print data, checking procedure S104 is directly entered.Fingerprint and device password are all
It is used to the necessary condition of removable storage device.Fingerprint and device password initialization step are exactly by fingerprint and device password
It is placed in the memory module of removable storage device.
When having fingerprint inside memory module, need to use removable storage device, then will be verified.Verification step
Suddenly comprise the steps：S104 computers obtain user input equipment code data and are dealt into removable storage device, and mobile phone passes through
Fingerprint module obtains finger print data and is dealt into removable storage device by the first near-field communication module, and removable storage device is obtained
After getting finger print data and device password data, and it is compared with the data in removable storage device, i.e. step S105, such as
Fruit all passes through then to continue below step.Otherwise enter step S106 this method to terminate.Here checking will be carried out after receiving simultaneously
Checking, rather than verified one by one, it thus is avoided that disabled user is cracked one by one.As long as checking has one simultaneously
Mistake be exactly not all right, and disabled user do not know that error, increased and crack difficulty, simultaneously because verification process is being moved
Carry out inside formula storage device, this equipment does not have autgmentability, and for computer, this equipment is difficult to invade and breaks
Solution.
It is verified, represents user and there is the right for using the removable storage device, then enters step S107,
Step S107 computer judges whether removable storage device has username and password information；Here computer why is needed to sentence
Disconnected, it is could to be interacted with people due to computer, but computer is only to obtain a result, the process of judgement also needs to moving
In dynamic formula storage device.
Removable storage device does not have username and password information, enters step S108 username and password initialization step
Suddenly, after the completion for the treatment of user name and cryptographic initialization step, server generation the first encryption rule related to user name, second add
Close rule corresponding with the first encryption rule first decrypts rule the second decryption rule corresponding with the second encryption rule, returns
First encryption rule and the second decryption rule enter data storing steps S109 and S110 to removable storage device；Portable
Storage device has username and password information, is directly put into data storing steps S109 and step S110.User name and close
Code is logged on the key of server because user name password can be unique, but finger print data according to sampled point not
With, it is likely that it is not unique.If sampled point is little, then the finger print data of different fingerprints is possible to occur identical.Such as
Fruit is directly logged in using finger print data, then when user's radix is very big, it is likely that have one or two finger print data
It is the same, can so causes data obfuscation.This is absolutely not allowed in data security arts.User name cryptographic initialization
Afterwards, be just stored with removable storage device username and password.But during use below, avoid the need for again
Input username and password, it is to avoid the leakage of username and password.
Data storing steps comprise the steps：Including the step of reading service device file and uploading files to server
Step.Before upload should first reading service device file file directory, so under the catalogue that specifies, i.e., file can be stored
The fileinfo of the application can be file directory information, it is also possible to be directly file, be so equal to and download from a server text
Part.Wherein, include the step of reading service device file：Computer sends file and reads instruction, and removable storage device receives text
Part read instruction after, password is encrypted using the first encryption rule, by near-field communication module by file read instruction and
Password after user name and encryption is sent to mobile phone, mobile phone send user name, encrypt by mobile phone radio frequency module after password and
File reads instruction and arrives server, and server obtains the first decryption rule decrypted user name and password according to user name and verifies logical
Later, the fileinfo to reading is encrypted using the second encryption rule, and returns the fileinfo after encryption to mobile phone, hand
Machine sends the information after encrypting to removable storage device by near-field communication module, and removable storage device enters to fileinfo
Row decryption is simultaneously sent to computer, and computer shows the fileinfo for reading.
Here the encryption to password is using random the first encryption rule related to user name for generating when initialized
Then, this first encryption rule is stored in removable storage device, and is associated with user name, then corresponding first solution
Close rule storage is on the server.The encryption of the fileinfo of server adopts the second encryption rule, equally and user name
Association, then corresponding second decryption are stored in removable storage device and fileinfo can be decrypted.Movable type is deposited
The data that storage equipment is gone out can be encrypted using the first encryption rule except user name, and the data that server is returned all may be used
To be encrypted using the second encryption rule, i.e., these information are not transmission in plain text, thus considerably increase security.
Simultaneously because being associated using user name, the user name of each removable storage device is different, even if user name is identical, by
Different in being generated only when initialized at random, the removable storage device of such the past will fail, and so exist
When removable storage device is lost, it is only necessary to be updated by a new removable storage device again.So i.e.
Disabled user is made to have cracked the encryption and decryption rule of some removable storage device, also will not be to other removable storage devices
Threat is produced, the Information Security between different removable storage devices is substantially increased.
The step of uploading files to server includes：Computer detection is to after files passe operation.Upload operation can be inspection
The file for surveying user drags to upload frame operation, detects the fileinfo of the file that user drags, as the fileinfo for uploading.
Then computer sends the fileinfo for uploading and arrives removable storage device, and removable storage device generation random number, and to random
Number and fileinfo are encrypted.The encryption of file can be adopted and user name password the first encryption rule of identical, and adopt
First encryption rule is encrypted to password.The password after user name and encryption, file are believed by the second near-field communication module
Breath is sent to mobile phone, and password and fileinfo of the mobile phone after mobile phone radio frequency module sends user name, encrypts are to server, clothes
After business device is decrypted and verifies that username and password passes through, decryption obtains random number and fileinfo, and storage file information is to user
Under the corresponding file of name.
The transmission of data is carried out using random number here, and the fileinfo that can be allowed after encrypting is more chaotic, because with
Machine number is unique, and is to change always.Accordingly even when being identical file, its data after encrypting is also different
, it is to avoid disabled user reversely decrypting encryption rule, is increased and cracks difficulty by file constantly using variable quantity very little
Degree, it is ensured that security.Simultaneously because the passage of this programme data transfer is not through computer, so, computer need not be networked,
On the computer of some concerning security matters, just there is no the possibility for being cracked and shooting, it is ensured that the safety of computer data.By mobile phone radio frequency
Module is directly connected with base station, the possibility that also there is no monitoring.Mobile phone is also without data storage, removable storage device
Without data storage, the two all lost, and also not result in the problem of loss of data.Even if removable storage device is lost
, without fingerprint and corresponding device password, also have no idea to use removable storage device.And even with movable type
Storage device, and the username and password of inside cannot be got, because username and password will be used, portable storage
Equipment will be encrypted to which.The user discover that removable storage device lost, it is only necessary to user is changed on server
The password of name just because removable storage device will be cracked will need certainly for a period of time, even and if having cracked movement
Formula storage device, as username and password cannot pass through checking, is also otiose.Data safety is so substantially increased
Property, without the problem that concern of data is lost.
The change of password can also be like above step carry out, user first goes to buy a blank portable storage and sets
Standby, finger print data and device password is initialized then, then initialising subscriber name and password, then can be carried out more to password
Change, computer sends the password after a change directive, user name before, password and change, issues removable storage device,
Removable storage device, will be taken after user name, password before server verification pass through to being sent to server after these encryptions
After the password modification of business device storage, then the password after changing is returned to removable storage device, removable storage device by mobile phone
More new password.Certainly, in order to prevent Brute Force password, the intensity of password can be required, and such as want upper and lower case letter to add
Upper numeral, digit can be more than 10 etc..And if username and password checking is not by default number of times in one day,
Just no longer by the checking of the user name, it is to avoid Brute Force.
Specifically, the fingerprint and device password initialization step include：Computer sends acquisition fingerprint prompting, and movable type is deposited
Storage equipment waits fingerprint module to get finger print data, and after getting finger print data, removable storage device informs computer, computer
Acquisition device password prompting is sent, after waiting the keyboard of computer to get device password data, computer sends device password to shifting
Dynamic formula storage device, such removable storage device just store finger print data and device password data in, and enter verification step
Suddenly.
User name cryptographic initialization is similar with line and device password initialization, username and password initialization step include as
Lower step：Computer pop-up dialogue box points out user input username and password, after computer gets user name password, by near field
User name, password and finger print data are sent to mobile phone by communication module, then are sent to server by the mobile phone radio frequency module of mobile phone,
Whether, by checking, server is generated after being verified and user famous prime minister for server detection user name, password and finger print data
The first encryption rule, the second encryption rule the first decryption rule corresponding with the first encryption rule and the second encryption rule for closing
Corresponding second decryption rule, and the result, the first encryption rule and the second decryption rule are dealt into mobile phone, mobile phone is by near
Field communication module is forwarded to removable storage device, and removable storage device stores the first encryption rule and the second decryption is regular simultaneously
The result is forwarded to computer, computer judges to result that after the result is received judged result is by then
User name password storage in removable storage device, and data storing steps are entered, judged result is not used by then prompting
The username and password mistake of its input of family, this method terminate.
Further, data storing steps include following delete step：Computer detection is deleted after instruction to file, portable
After storage device receives file deletion instruction, password is encrypted using the first encryption rule, by near-field communication module
The password that file is deleted after instruction and user name and encryption is sent to mobile phone, mobile phone sends user by mobile phone radio frequency module
Password and file after name, encryption is deleted instruction and arrives server, and server obtains the first decryption rule decryption according to user name and uses
Name in an account book and password after being verified, delete file and delete the corresponding file of instruction.It is achieved thereby that the browsing and download of file, on
