(Android), Windows Phone etc..
It should be noted that species, shape, size to the display screen in terminal etc. is not limited, it is exemplary, eventually
Display screen on end can be LCDs etc..
In the first embodiment of the invention, the display screen of above-mentioned record is used for the interface for providing a user man-machine interaction,
When the mobile terminal of above-mentioned record is mobile phone, Fig. 3 is the front view for the mobile terminal being related in first embodiment of the invention, Fig. 4
For the rearview for the mobile terminal being related in first embodiment of the invention.
Fig. 5 is the flow chart of the first embodiment of the method for fingerprint recognition of the present invention, as shown in figure 5, this method includes step
Rapid 500 arrive step 503.
Step 500：Contact area when fingerprint recognition region is contacted by user is obtained, the fingerprint recognition region is located at eventually
The back side at end.
When user operates terminal screen, the terminal back side is just into vision dead zone, and therefore, the operation to the terminal back side is present
It is difficult.As shown in figure 4, the fingerprint recognition region of the embodiment of the present invention is located at the back side of terminal, can also be according to when actually implementing
According to position of the user using the habituation design fingerprint recognition region of mobile terminal.
Step 501：When the contact area is more than or equal to area threshold, fingerprinting operation cue is generated；Institute
Stating fingerprinting operation cue is used to point out user to input fingerprint recognition data.
In this step, trigger signal is generated when the contact area is more than area threshold, to trigger controlled motor generation
Fingerprinting operation cue；The fingerprinting operation cue includes following at least one：Optical signal, acoustical signal, vibration signal.
Here, area threshold is the minimum fingerprint image area that terminal can be recognized when carrying out fingerprint recognition operation, area
Threshold value can be minimum value of the user when inputting fingerprint recognition data with the contact area in fingerprint recognition region, and area threshold can
To carry out the modification of adaptability according to the operating habit of different user.For example, the area for the fingerprint image that terminal is collected is at least
For 9 square centimeters when terminal can just obtain enough finger print informations, further identify current fingerprint image.
It is understood that when terminal bonnet is designed to smooth flat, being now placed in the fingerprint identification area at the terminal back side
The top in domain does not have any indicative mark, to help user to be accurately positioned fingerprint identification area when that can not observe the terminal back side
Domain, therefore in order to solve the problem of fingerprint recognition region is positioned, when user's finger contacts are to fingerprint recognition region, it should first sentence
Whether the operation of disconnected active user is fingerprint recognition operation, and basis for estimation is：User and the contact area in fingerprint recognition region are
It is no to be more than or equal to area threshold.When contact area is less than area threshold, the operation for illustrating now is probably the mistake of user
Touching or other non-fingerprint recognition operations；Trigger signal is generated when contact area is more than or equal to area threshold, to touch
Send out controlled motor generation fingerprinting operation cue.
It is exemplary, given birth to when the fingerprint recognition region at the mobile phone back side and the contact area of user's finger are more than area threshold
Into trigger signal, to trigger the work of the linear motor on mobile phone, linear motor can drive mobile phone vibrations (i.e. generation vibrations when working
Signal), to remind the position that user currently contacts to carry out fingerprint recognition operation (i.e. fingerprint recognition region positioning is completed).
, can also be by triggering the other equipment on mobile phone, to produce optical signal, acoustical signal or various promptings letter during actual implementation
Number combination come remind user fingerprints identification region positioning completion, can start perform fingerprint recognition operation.
Step 502：Obtain the fingerprint recognition data collected when the fingerprint recognition region is currently contacted by user.
Preferably, fingerprint recognition data can include it is following at least one：Finger print data, pressure value；Finger print data is used for
The fingerprint image collected is represented, pressure value is used to represent the pressure size that fingerprint recognition region is applied in.
It is understood that after the completion of being positioned in fingerprint recognition region, user applies in the region currently determined to terminal
Certain pressing dynamics operates to perform fingerprint recognition, and terminal obtains the fingerprint collected when fingerprint recognition region is contacted by user
Identification data, judges whether current operation is default fingerprint fingerprint recognition operation for further.
Finger print data can be acquired by image acquiring sensor, and pressure value can pass through fingerprint identification area configuration of territory
Pressure sensor be acquired, then the finger print data collected and pressure value are passed to the central processing unit of terminal
(Central Processing Unit, CPU) is handled and analyzed.
Step 503：When the fingerprint recognition data meet default fingerprinting operation condition, corresponding operation is performed.
Preferably, default fingerprinting operation condition can include：The fingerprint number that finger print data is prestored with terminal
According to sample matches, and pressure value is more than pressure threshold；
Or, default fingerprinting operation condition can include：The finger print data that finger print data is prestored with terminal
Sample matches；When the fingerprint recognition data meet default fingerprinting operation condition, corresponding operation is performed, including：Referring to
When line identification data meets default fingerprinting operation condition, control terminal is obtained when fingerprint recognition region is currently contacted by user
Pressure value, when pressure value is more than pressure threshold, performs corresponding operation.Optionally, meet default in fingerprint recognition data
During fingerprinting operation condition, the pressure when pressure sensor collection fingerprint recognition region in control terminal is currently contacted by user
Value, then judge whether pressure value is more than pressure threshold.
Or, default fingerprinting operation condition includes：Pressure value is more than pressure threshold；Met in the fingerprint recognition data
During default fingerprinting operation condition, corresponding operation is performed, including：Default fingerprinting operation condition is met in fingerprint recognition data
When, control terminal obtains finger print data when fingerprint recognition region is currently contacted by user, is deposited in advance with terminal in finger print data
During one finger print data sample matches of storage, corresponding operation is performed.Optionally, default fingerprint is met in fingerprint recognition data
During operating condition, the fingerprint number when image acquiring sensor collection fingerprint recognition region in control terminal is currently contacted by user
According to, then judge finger print data whether a finger print data sample with being prestored in terminal matches.
When actually implementing, terminal prestores at least one finger print data sample before fingerprint recognition operation, and terminal passes through
" fingerprint management " gathers and preserved at least one finger print data sample.For example, when user's input right hand thumb, forefinger, in
Refer to and left hand middle finger fingerprint image as finger print data sample when, then user can only could be realized pair by this four fingers
Terminal fingerprints identification operation.Here, all finger print data samples can correspond to identical executive mode, or each fingerprint
Sample data corresponds to different executive modes respectively.
Exemplary, when the fingerprint recognition region of terminal is pressed by the right hand forefinger of user, terminal judges current obtain
Fingerprint recognition data whether meet default fingerprinting operation condition, the fingerprint image that will currently obtain and stored in terminal
Right hand thumb, forefinger, the fingerprint image of middle finger and left hand middle finger are matched one by one, and the fingerprint currently obtained is found after matching
The match is successful for the fingerprint image of image and right hand forefinger, and current right hand forefinger is more than pressure to the pressing dynamics in fingerprint recognition region
Force threshold, determines the corresponding executive mode of right hand forefinger, performs corresponding operation.
Here, maloperation caused by progress pressure value is relatively in order to avoid being touched due to the false touch of user's finger, due to
When finger encounters fingerprint recognition region by mistake, general finger is smaller to the pressing dynamics in the region, and the pressure value collected is less than pressure
Force threshold, therefore can judge whether current operation is that user touches operation by mistake by pressure value.Pressure threshold can be used
The pressing dynamics minimum value or user that family applies in input pressure data sample to fingerprint recognition region are often carried out
The average value of the pressing dynamics applied when fingerprint recognition is operated to fingerprint recognition region, pressure threshold can also be inputted according to user
Fingerprint recognition data optimize, to improve the accuracy of fingerprint recognition.
It can also include in this step：When the fingerprint recognition data meet default maloperation condition, ignore correspondence
Operation.
Preferably, default maloperation condition can include：The fingerprint recognition data of continuous acquisition to n times are satisfied by presetting
Fingerprinting operation condition, and finger print data all points to same finger, and n is more than or equal to frequency threshold value；N takes whole more than 1
Number.
It is understood that in user's handheld terminal (such as：Mobile phone, IPAD etc.), the pressing that finger may continue is whole
Hold the back side fingerprint recognition region, and now continuous collecting to fingerprint recognition data be satisfied by default fingerprinting operation condition,
If terminal performs corresponding operation only according to whether default fingerprinting operation condition is met, lasting maloperation can be caused.
In order to avoid this lasting maloperation, it can be come by judging whether fingerprint recognition data meet default maloperation condition
Judge terminal whether by user's finger Continued depression.Here, it is pressed if fingerprint recognition region is lasting, terminal can be in fixation
The current fingerprint recognition data of time interval continuous acquisition, the fingerprint recognition data currently obtained when terminal with it is last (i.e.
Before Fixed Time Interval) the fingerprint recognition data that obtain are satisfied by default fingerprinting operation condition, and finger print data is all pointed to together
One finger, n values increase by 1, when n values are more than or equal to frequency threshold value, determines that terminal, by user's finger Continued depression, is ignored
Corresponding operation.When actually implementing, when terminal is restarted, n values are set to 0；The current finger print identification data that terminal is obtained is unsatisfactory for
Default fingerprinting operation condition, or current finger print data are not directed to same finger with the last finger print data collected
When, n values are set to 0.
Exemplary, frequency threshold value takes 5 in default maloperation condition, when fingerprint recognition region is persistently pressed, eventually
End gathers a fingerprint recognition data every 1s, when terminal the 1st second, the fingerprint recognition data that collect for the 2nd second to the 5th second it is equal
Meet default fingerprinting operation condition, and finger print data, when all pointing to same finger, n values are equal to 5, now fingerprint recognition data
Meet default maloperation condition, the corresponding executive mode of terminal disregards current finger print identification operation.
The method of fingerprint recognition disclosed in the embodiment of the present invention can also include：For each execution fingerprint recognition operation
Finger sets corresponding executive mode respectively.
Correspondingly, after fingerprint recognition data meet default fingerprinting operation condition, in addition to：It is determined that currently performing fingerprint
The finger of operation is recognized, based on the current finger for performing fingerprint recognition operation, corresponding operation is performed.
When actually implementing, identical executive mode can be set for the finger of all typing finger print datas of user；Such as：With
Family in advance stores the finger print data of the thumb, forefinger and middle finger of oneself right hand into terminal, and thumb, forefinger and middle finger are equal
The operation of correspondence first corresponds to the second operation.Difference can also be set for the finger of all typing finger print datas of user respectively
Executive mode.For example, thumb, the first operation of forefinger and middle finger difference counterpart terminal, the second operation and the 3rd operation.This
In, first operation, second operation, the 3rd operation can by User Defined or terminal profile default action, such as：
First operation counterpart expenditure operation, the second operation correspondence unblock operation, the 3rd operation correspondence wake operation.
In this step, when the finger of all typing finger print datas of user sets different executive modes respectively, refer to currently
Line identification data is met after default fingerprinting operation condition, further to determine the current finger for performing fingerprint recognition operation, base
In the finger for currently performing fingerprint recognition operation, corresponding operation is performed.For example, in user using right hand forefinger to the terminal back side
Fingerprint recognition region when performing fingerprint recognition operation, can also be according to collection after the operation of correct fingerprint recognition is defined as
The fingerprint image arrived determines that the current finger for performing operation is right hand forefinger, so as to perform the corresponding unblock operation of forefinger.
In order to be able to more embody the purpose of the present invention, on the basis of first embodiment of the invention, such scheme is carried out
It is further to illustrate.
