Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, wherein certainly
Begin to same or similar label eventually represent same or similar element or there is the unit of same or like function
Part.The embodiment described below with reference to accompanying drawing is exemplary, is only used for explaining the present invention, and can not
It is interpreted as limitation of the present invention.On the contrary, embodiments of the invention include falling into attached claims
All changes, amendment and equivalent in the range of spirit and intension.
Fig. 1 is the schematic flow sheet of the biological information certifying method that one embodiment of the invention proposes.The present embodiment
It is configured in biological information authentication device illustrate with this biological information certifying method.The reality of the present invention
Execute example can apply when user uses the biometric information authentication function of mobile terminal.Wherein, mobile terminal can
To be the hardware with various operating system such as smart mobile phone, panel computer, personal digital assistant, e-book
Equipment.Biometric information authentication function can during the screen of mobile terminal is unlocked by such as user,
The bio information needing input coupling can be unlocked the function of operation, or, it is also possible to such as user
Carrying out other function of mobile terminal in the middle of the arranging of password locking, this is not restricted by the embodiment of the present invention.
Seeing Fig. 1, this biological information certifying method includes following several step:
S11: when determining the first biological characteristic authentication failure to user, the biological characteristic of Resurvey user
Obtain the second biological characteristic.
User is during using mobile terminal at present, can use the biometric information authentication function of mobile terminal
Mobile terminal is unlocked or wakes up up, such as, user use mobile terminal move payment time,
Biometrics password can be pre-set, before paying, by mobile terminal side typing biological characteristic, by moving
The biological characteristic collected is mated by dynamic terminal built-in program with the biological characteristic prestored, when fitting through,
Trigger mobile terminal and carry out delivery operation.
In an embodiment of the present invention, the first biological characteristic is the bio information that mobile terminal gathers user first
The biological characteristic obtained, the second biological characteristic is the life that the bio information of mobile terminal Resurvey user obtains
Thing feature.
Wherein, appointing during bio information is iris information, face information, acoustic information, and heart rate information
A kind of.
Such as, when bio information is iris information, the first biological characteristic can be the iris picture of user；
When bio information is face information, the first biological characteristic can be the face picture of user；Work as bio information
During for acoustic information, the first biological characteristic can be the voice data of user；When bio information is heart rate information
Time, the first biological characteristic can be the heart rate data of user, owing to bio information can uniquely identify user's
Identity information, first biological characteristic of different users is different.
In an embodiment of the present invention, when mobile terminal collects first biological characteristic of user, can be by first
The 3rd biological characteristic that biological characteristic prestores with mobile terminal side mates, and wherein, the 3rd biology is characterized as
The biological characteristic that user prestores at mobile terminal side, in the first biological characteristic and the success of the 3rd biometric matches
After, mobile terminal can identify and pass through the user authentication belonging to the first biological characteristic, and triggering following is to mobile whole
End unblock or wake up up wait operate.
It is understood that when biological characteristic to user each time is authenticated, certification all can be there is and loses
Losing rate, authentification failure rate for example, 3%, the unsuccessful factor of certification can such as include: mobile terminal collection
To the mass fraction of biological characteristic of user be not up to preset fraction threshold value, or, in the matter of biological characteristic
When amount mark reaches preset fraction threshold value, the first biological characteristic and the error of the 3rd biometric matches.
In an embodiment of the present invention, can be when determining the first biological characteristic authentication failure to user, weight
The new biological characteristic gathering user obtains the second biological characteristic.
S12: the 3rd biological characteristic prestored with mobile terminal side by the second biological characteristic mates, with to
Second biological characteristic at family is authenticated.
Such as, the 3rd biological characteristic that the second biological characteristic prestores with dynamic end side is mated, with to
Second biological characteristic at family is authenticated.
Such as, if the second biological characteristic and the 3rd biological characteristic are consistent in range of error, then can sentence
Fixed second biological characteristic authentication is passed through, can be unlocked afterwards, the operation such as payment, otherwise, to the
Two biological characteristic authentications do not pass through, and refuse associative operation.
In the embodiment of the present invention, when determining the first biological characteristic authentication failure to user, Resurvey is used
The biological characteristic at family obtains the second biological characteristic, is authenticated with the second biological characteristic to user, due to
When biological characteristic to user is authenticated each time, (authentification failure rate is such as all to there is authentification failure rate
It is 3%), therefore, the embodiment of the present invention re-starts certification, double probate to second biological characteristic of user
The most failed probability can be 3% × 3%, is 0.09%, owing to 3% much larger than 0.09%, can effectively reduce
Biometric information authentication mortality, i.e. promotes biometric information authentication success rate.
In the present embodiment, by when determining the first biological characteristic authentication failure to user, Resurvey is used
The biological characteristic at family obtains the second biological characteristic, is authenticated with the second biological characteristic to user, wherein,
First biological characteristic and the biological information that the second biological characteristic is the user that different time node collects,
Biometric information authentication success rate can be effectively improved.
