Description
Technical field
The present invention relates to encrypting fingerprint technical fields, the in particular to fingerprint encryption method of high security level.
Background technique
With network technology and information-based high speed development, for personal information and account safety also increasingly by people
Attention, in existing encryption technology, generally use biological characteristic identification and set secret signal identification two ways.
Wherein, it is identified using the biological characteristic of individual consumer, if fingerprint, face are as the methods of, iris, due to having only
One property and unchangeable property almost refer to as the synonym of living things feature recognition in electronic information equipment highly developed today
Line encryption has been widely used in mobile phone unlock, e-payment, file security, information security, access control, attendance management and card
All kinds of occasions for needing computer to carry out automatic identity authentication such as management.
However, the safety of encrypting fingerprint still faces under the trend that encrypting fingerprint gradually becomes mainstream manner of decryption
Larger challenge.Such as user when using fingerprint can on fingerprint collecting head fingerprints trace, and these fingerprint traces are deposited
A possibility that being used to duplication fingerprint；Offender usurps user fingerprints progress in the unconscious situation of user for another example
Illegal activity etc..
And it is identified using the secret signal of personal set, for example language, the character of setting of the text, setting that set are suitable
Sequence, time interval of setting etc., before the identification technology development of biological characteristic, most of identification method belongs to setting secret signal
Identification.
The advantages of this recognition methods is to set secret signal to belong to personal interior mind consciousness, it is not easy to is stolen, the disadvantage is that holding
It is easily cracked by certain algorithm, does not have uniqueness.
Therefore, it is necessary to be improved to existing encryption technology, the shortcomings that prior art can be overcome.
Summary of the invention
In view of the above drawbacks of the prior art, the present invention provides the fingerprint encryption method of high security level, the mesh of realization
First is that formulating the knowledge for both being provided simultaneously with advantage by the way that biological characteristic and setting two kinds of recognition methods of secret signal to be combined
Other method.
To achieve the above object, the invention discloses the fingerprint encryption method of high security level, including input/output module,
Fingerprint read module, finger print data coding module and data memory module；Steps are as follows：
A. the line read module reads one or more finger print informations of user's input and is transported to the fingerprint number
According to coding module；
B. the fingerprint number that the finger print data coding module is inputted according to the finger print information and the user is to finger
Line is encoded, and finger-print codes are obtained；And each finger print information and the corresponding finger-print codes are transported to the number
It is stored according to memory module；
What the preset password and the data memory module that c. the input/output module sets the user stored
Each finger print information and the corresponding finger-print codes are compared, and obtain preset fingerprint password, and be stored in the number
According to memory module, the setting of password is completed；
D. when user unlocks, the fingerprint read module includes one or more finger print informations by what is read
Unlock finger-print cipher, by each preset finger representated by collected sequencing and the preset fingerprint password
Line information compares, and nationality exports comparing result by the input/output module.
Preferably, in step c, the preset password of user's setting further includes preset interval time, described default
Interval time refers to the time difference between every two fingerprint input time, and the preset interval time information nationality is defeated by the input
Module is shown out.
Preferably, in the step d, during user's unlock, the fingerprint read module is collected
Interval time in the unlock finger-print cipher between every two finger print information is required to and the corresponding preset interval time
It compares.
Preferably, in the step c, the finger-print cipher is one group of finger-print codes corresponding with the finger print information.
Preferably, it is applied to mobile phone to unlock, the fingerprint read module reads the finger of ten fingers of the user
Line information, and nationality by the finger print data coding module by ten finger print informations be successively encoded to number 0 to number 9, and
It is stored in the data memory module.
Preferably, the input/output module chooses several numbers into number 9 in number 0 according to what is set according to user
The password that word is formed, obtains the finger-print cipher as corresponding to the password, and finger-print cipher is stored in the data and is deposited
Store up module.
Beneficial effects of the present invention：
Nationality of the present invention by " fingerprint " will be had chosen in biological characteristic, set secret signal in have chosen " character sequence " and " when
Between be spaced " several encrypted features are combined, biological characteristic and setting two kinds of recognition methods of secret signal are combined, formulated simultaneously
The recognition methods for having the two advantage.
The technical effect of design of the invention, specific structure and generation will be described further below, with fully
Solve the purpose of the present invention, feature and effect.
Specific embodiment
Embodiment
The fingerprint encryption method of high security level, the first purpose of realization be by by biological characteristic and setting two kinds of secret signal
Recognition methods is combined, and formulates the recognition methods for being provided simultaneously with the two advantage.
To achieve the above object, the invention discloses the fingerprint encryption method of high security level, including input/output module,
Fingerprint read module, finger print data coding module and data memory module；Steps are as follows：
A. line read module reads one or more finger print informations of user's input and is transported to finger print data coding mould
Block；
B. finger print data coding module encodes fingerprint according to the fingerprint number that finger print information and user input, and obtains
