Referring to Fig. 1, Fig. 1 is the flow diagram of the method for fingerprint authentication provided by the embodiments of the present application, flow can be with
Including：
In step S101, when needing to carry out fingerprint authentication, the predetermined inductive region on terminal screen is monitored.
Many significant datas of user are stored with terminal, such as photo, file, bank account information and payment cipher
Deng.In general, user can carry out safeguard protection by the way of certain to terminal, to prevent significant data from revealing.Such as user
Can the typing finger print information in terminal in advance, when needing to operate significant data, terminal can require user to carry out
Fingerprint authentication.Only when fingerprint authentication by when, terminal can just allow user to operate significant data.
However, in life, there is also stolen possibility for the fingerprint of user.Such as user hand can and it is various
Thing contact, this causes the fingerprint of user to stay on the thing contacted.This leaves and can multiply to unauthorized person such as hacker
Machine, hacker only need with clay make a fingerprint reverse mould, it is possible to usurp the finger print information of user.That is, in correlation technique,
Fingerprint recognition still has loophole in terms of security.
In the step S101 of the embodiment of the present application, when needing to carry out fingerprint authentication, than if desired for use fingerprint authentication pair
When terminal screen is unlocked operation, terminal first can be monitored the predetermined inductive region on screen, default to detect this
Whether the electric signal of induction region changes.
If detect that the electric signal in the predetermined inductive region does not change, then terminal can suspend fingerprint authentication behaviour
Make, until the electric signal in predetermined inductive region changes, then carry out corresponding fingerprint authentication.
If detect that the electric signal in the predetermined inductive region changes, then enter step S102.
In step s 102, if detecting, the electric signal in the predetermined inductive region changes, and records the predetermined inductive
Electric signal changed first moment in region.
For example terminal detects that predetermined inductive region causes the electricity in the predetermined inductive region because being pressed by the finger of user
Signal is changed, and terminal can record electric signal changed first moment in the predetermined inductive region at this time.
For example, because user's finger has pressed the screen in predetermined inductive region, cause the screen backlight in the predetermined inductive region
In layer the numerical value of built-in test using capacitance sensor to electric current and/or voltage is changed, i.e. the predetermined inductive region
Electric signal changes, and terminal can record capacitive sensing built-in in the screen back photosphere in the predetermined inductive region at this time
The time when electric current of device and/or the numerical value of voltage change, i.e. the first moment.
In step s 103, the finger print information of active user is gathered, and records the second moment for collecting the finger print information.
For example after it recorded for the first moment, terminal can gather the finger of active user by fingerprint Identification sensor
Line information, and record time when collecting the finger print information of the active user, i.e. the second moment.
In step S104, if detecting, first moment and second moment meet preset condition, and basis collects
The finger print information carry out fingerprint authentication.
For example after it recorded the first moment and the second moment, terminal can detect first moment and the second moment
Whether preset condition is met.
If detect that first moment and the second moment meet preset condition, then terminal can be according to passing through finger before
The finger print information for the active user that line identification sensor collects carries out fingerprint authentication.For example, detect first moment and
In the case that second moment met preset condition, terminal will can prestore in the finger print information for the active user that collected and terminal
Target fingerprint information be compared.If determine that active user is validated user by fingerprint comparison, then terminal can be right
Screen is unlocked operation, so that active user can be with this terminal of normal use.If determine currently to use by fingerprint comparison
Family is not validated user, then terminal can not be unlocked screen, etc..
If detect that first moment and the second moment are unsatisfactory for preset condition, then terminal can be without follow-up
Fingerprint verification operation.
It is understood that in the embodiment of the present application, execution condition is provided with for fingerprint verification operation, which is
First moment and the second moment meet certain preset condition.Wherein, which is the predetermined inductive region of terminal screen
Electric signal at the time of change, second moment collected for fingerprint Identification sensor the finger print information of active user when
Carve.Only in the case where the execution condition is satisfied, terminal can just allow to carry out fingerprint verification operation.Therefore, the application is real
The security of fingerprint authentication can be strengthened by applying example, even if fingerprint is stolen, as long as appropriator does not know the execution of fingerprint verification operation
Condition, then appropriator still can not steal the information preserved in terminal by fingerprint authentication.
Referring to Fig. 2, Fig. 2 is another flow diagram of the method for fingerprint authentication provided by the embodiments of the present application, flow
It can include：
In step s 201, terminal obtains user and knows from the predetermined inductive region touched on the terminal screen to fingerprint is touched
The multiple sample values for the duration that the process of individual sensor is spent.
In step S202, terminal calculates the average value of the plurality of sample value, and determines preset duration according to the average value.
For example step S201 and S202 can include：
Terminal can select one piece of region on the screen as predetermined inductive region in advance.Referring to Fig. 3, with terminal screen
Exemplified by display area 10 and non-display area 20, display area 10 is the region for showing the pictures such as word, image, non-
Display area 20 is for placing front camera, receiver, ambient light sensor, proximity sensor and fingerprint Identification sensor
Region.Terminal by 10 bottom of display area on screen and can account for the region of a quarter of display area area in advance
It is set as predetermined inductive region 30.Fingerprint Identification sensor is arranged on the non-display area 20 of terminal screen bottom.
In one embodiment, initial phase being configured, user can enter " setting " interface of terminal, and
First clicked on according to terminal notifying or flicking or again by the predetermined inductive region on screen, then press fingerprint Identification sensor, at the same time
Terminal can record the time point that user's finger touches predetermined inductive region, and user's finger presses fingerprint Identification sensor
Time point.Then, terminal can calculate the time interval at above-mentioned two time point, which is that user is default from touching
One sample value of the duration that induction region is spent to the process for touching fingerprint Identification sensor.It is understood that user
Aforesaid operations can be repeated several times, such terminal can get multiple sample values.
After multiple sample values are got, terminal can calculate the average value of the plurality of sample value.Then, terminal can be with
One preset duration is determined according to the average value.The preset duration can represent that user feels from touch is default under normal circumstances
Region is answered to the duration for touching the required cost of this process of fingerprint Identification sensor.
For example terminal can obtain 5 sample values, and the average value of this 5 sample values is calculated, it is then flat further according to this
Average determines preset duration.For example, the average value can be determined as preset duration by terminal, alternatively, terminal can also be at this
Certain time length is increased or decreased on the basis of average value, obtains target duration, and the target duration is determined as preset duration.
It is understood that step S201 and S202 are the step of predefining out preset duration.
In step S203, when needing to carry out fingerprint authentication, the predetermined inductive region on terminal-pair screen is monitored.
For example user is pre-set and the screen in screen lock state is unlocked using fingerprint authentication.When needs pair
Terminal screen is unlocked, that is, when needing to carry out fingerprint authentication, terminal can be monitored the predetermined inductive region on screen,
To detect whether the electric signal in the predetermined inductive region changes.
For example, terminal screen is the screen with pressure sensitive.The built-in condenser type biography in the backlight layer below screen
Sensor, the capacitance type sensor are able to detect that the slight change of pressure between screen skin glass and backlight layer, that is, work as user
When finger is pressed against on the screen with pressure sensitive, capacitance type sensor can detect the change of electric current and magnitude of voltage.When
When user's finger presses screen, terminal system aspect can be according to the electric current and magnitude of voltage that these test using capacitance sensors arrive
Change, responds the pressing operation of user's finger.
Therefore, when needing to be unlocked the screen in screen lock state using fingerprint authentication, terminal can detect this
Whether built-in capacitance type sensor detects that the numerical value of electric current and/or voltage occurs in the screen back photosphere in predetermined inductive region
Change.
If capacitance type sensor is not detected by its electric current and/or the numerical value of voltage changes, i.e. predetermined inductive region
Electric signal do not change, then terminal can suspend fingerprint verification operation, until predetermined inductive region electric signal occur
Change, is carrying out corresponding fingerprint authentication.
If the numerical value of test using capacitance sensor to its electric current and/or voltage changes, i.e. predetermined inductive region
Electric signal changes, then enters step S204.
In step S204, if detecting, the electric signal in the predetermined inductive region changes, and it is default that terminal records this
Electric signal changed first moment of induction region.
For example because user's finger has pressed the screen in predetermined inductive region, cause the screen backlight in the predetermined inductive region
The numerical value of built-in test using capacitance sensor to its electric current and/or voltage is changed in layer, i.e. the predetermined inductive region
Electric signal change, terminal can record condenser type built-in in the screen back photosphere in the predetermined inductive region and pass at this time
The time when electric current of sensor and/or the numerical value of voltage change, i.e. the first moment.
In step S205, terminal gathers the finger print information of active user, and records and collect the second of the finger print information
Moment.
For example after it recorded for the first moment, terminal can gather the finger of active user by fingerprint Identification sensor
Line information, and record time when collecting the finger print information of the active user, i.e. the second moment.
In step S206, terminal calculates the time interval at first moment and second moment.
For example after the first moment and the second moment is got, terminal can calculate first moment and the second moment
Time interval.
Then, when whether terminal can detect the time interval at first moment and the second moment less than or equal to presetting
It is long.
If detect that the time interval at first moment and the second moment is more than preset duration, then it is considered that first
Moment and the second moment are unsatisfactory for default condition, and terminal can be without follow-up fingerprint verification operation at this time.
If detect that the time interval at first moment and the second moment is less than or equal to preset duration, then enter step
Rapid S207.
In step S207, if detecting, the time interval is less than or equal to preset duration, terminal determine this first when
Carve and second moment meets preset condition, and fingerprint authentication is carried out according to the finger print information collected.
For example preset duration is 1 second.Terminal detects that the time interval at first moment and the second moment is less than 1 second
Clock, then terminal can determine that first moment and the second moment meet default condition.In this case, terminal can root
Corresponding fingerprint authentication is carried out according to the finger print information of the active user collected before.
For example, terminal can be by the fingerprint of the owner prestored in the finger print information of the active user collected and terminal
Information is compared.If determine that active user is owner by fingerprint comparison, then terminal can be unlocked screen behaviour
Make, so that active user can be with this terminal of normal use.If determine that active user is not owner by fingerprint comparison, then
Terminal can not be unlocked screen, etc..
In one embodiment, if being detected in S204, the electric signal in the predetermined inductive region changes, terminal
The step of recording electric signal changed first moment in the predetermined inductive region, can include：
If detecting, the electric signal in the predetermined inductive region changes, and terminal obtains user's finger and presses the default sense
Answer the pressure value in region；
If detecting, the pressure value is in preset range, and the electric signal that terminal records the predetermined inductive region becomes
The first moment changed.
For example the screen of terminal is the screen with pressure sensitive, can perceive user's finger dub, flicking and again by
The difference of screen.In this case, the predetermined inductive region on user's finger pressing screen, causes predetermined inductive region
In screen back photosphere built-in test using capacitance sensor to electric current and magnitude of voltage change when, terminal can obtain use at the same time
Family finger presses the pressure value in the predetermined inductive region.
Then, terminal can detect whether the pressure value is in preset range.If so, then terminal can record the default sense
Answer electric signal changed first moment in region.If it is not, then terminal can be without fingerprint authentication.
For example, range of pressure values when above-mentioned preset range corresponds to user's finger flicking screen.That is, fingerprint authentication is held
Row condition is exactly the screen in requirement user elder generation flicking predetermined inductive region.That is, only when terminal detects user's flicking
During the screen in predetermined inductive region, terminal can just record electric signal changed first moment in the predetermined inductive region.Such as
Fruit terminal detects that user dubs or again by the screen in predetermined inductive region, then terminal can not record the predetermined inductive region
Electric signal changed first moment, i.e. terminal will be without fingerprint authentication.
In another embodiment, terminal can also determine to be used to judge the first moment and second as follows
Whether the moment meets the preset duration of preset condition：
Terminal obtains the facial image of user；
Terminal determines the age value of the user according to the facial image；
Terminal obtains target duration, and the target duration is determined as preset duration according to the age value.
For example terminal does not get the sufficient amount of from predetermined inductive region is touched to touch fingerprint recognition sensing of user
The sample value for the duration that the process of device is spent, as terminal only gets 1 sample value, then terminal will be unable to according to sample value
Average value determine preset duration.In this case, terminal can also obtain the facial image of user, and according to the face figure
As the age value of prediction the user.Then, terminal can according to predict come age value, obtain a target duration, and will
The target duration is determined as preset duration.
For example terminal can set corresponding duration for different age values in advance, and generate on age value and duration
Mapping table.So, after the age value of the user is determined according to the facial image of user, terminal can inquire about this
Mapping table, and target duration corresponding with the age value of the user is therefrom obtained, then the target duration is determined as presetting
Duration.
For example, age value 1~10 when a length of 1.5 seconds, age value 11~40 when a length of 1 second, age value is 40
More than when a length of 1.3 seconds, etc..
Fig. 4 to Fig. 8 is referred to, Fig. 4 to Fig. 8 is the scene signal of the method for fingerprint authentication provided by the embodiments of the present application
Figure.
For example as shown in figure 4, terminal is in screen lock state.Wherein, which will be located at display area bottom on screen in advance
Portion simultaneously accounts for the region of a quarter of display area area and is set as predetermined inductive region.Fingerprint Identification sensor is arranged on terminal
The non-display area of screen bottom.The terminal screen is the screen with pressure sensitive.It is built-in in the backlight layer below screen
Capacitance type sensor, the capacitance type sensor are able to detect that the trickle change of pressure between screen skin glass and backlight layer
Change, i.e., when user's finger is pressed against on the screen with pressure sensitive, capacitance type sensor can detect electric current and voltage
The change of value.User, which pre-sets, is unlocked the screen in screen lock state using fingerprint authentication.
When needing that terminal screen is unlocked, that is, when needing to carry out fingerprint authentication, terminal can be to default on screen
Induction region is monitored, to detect whether the electric signal in the predetermined inductive region changes.
For example, as shown in figure 5, terminal detects that user's finger has pressed the screen in predetermined inductive region, cause this default
The numerical value of built-in test using capacitance sensor to electric current and/or voltage is changed in the screen back photosphere of induction region,
That is the electric signal in the predetermined inductive region changes, and terminal can record the screen back photosphere in the predetermined inductive region at this time
In the first moment of the built-in electric current of capacitance type sensor and/or the numerical value of voltage when changing.
Then, as shown in the direction of arrow in Fig. 5, user's finger is from pressing position quick sliding to fingerprint Identification sensor
On.As shown in fig. 6, terminal gathers the finger print information of active user by fingerprint Identification sensor, and record and collect the fingerprint
The second moment during information.
After the first moment and the second moment is got, terminal can calculate the time at first moment and the second moment
Interval.Then, terminal can detect first moment and whether the time interval at the second moment is less than or equal to preset duration.
For example, preset duration is 1 second.And terminal detects that the time interval at first moment and the second moment is less than 1
Second, then terminal can determine that first moment and the second moment meet default condition.In this case, terminal can be with
The finger print information of the owner prestored in the finger print information of the active user collected and terminal is compared.It is for example, logical
Cross fingerprint comparison and determine that active user is owner, then terminal can be unlocked screen operation, so that active user
Can be with this terminal of normal use.As shown in fig. 7, entering application interface after terminal screen unlock, extremely L is applied including application A.
In some embodiments, if the time interval at the first moment and the second moment is more than preset duration, or pass through
Fingerprint comparison determines that active user is not owner, then terminal can not be unlocked screen, etc..For example terminal can
With pop-up dialogue box, unlock failure, or return unlock interface prompting user is prompted to input password and be unlocked.In addition, terminal
The number of unlock failure can also be recorded.When the number of unlock failure reaches preset times, terminal can send alarm sound,
To improve the security of terminal.
In other embodiments, user's finger can be operated as follows：First flicking screen, slide again
Move, finally press fingerprint Identification sensor, so that terminal can collect finger print information.As shown in figure 8, for example, user's finger
Movement locus direction can as shown by arrow a, i.e., user's finger first presses a certain position in the predetermined inductive region upper left corner, then
Fingerprint Identification sensor is slided into the lower right corner.Alternatively, as shown by the arrowb, i.e., user's finger is first pressed in predetermined inductive region
Between a certain position, slide into fingerprint Identification sensor still further below.Alternatively, as indicated by arrow c, i.e., user's finger first presses default
The a certain position in the induction region upper right corner, then inferior horn slides into fingerprint Identification sensor to the left.
In addition, user can also combine mode of operation and period.For example, user can be set in advance in currently
Time is in 12:In the case of before 00, fingerprint authentication is carried out using the mode in Fig. 8 shown in arrow a, i.e. terminal need to detect
The sliding trace direction of user's finger is to slide into fingerprint Identification sensor, and user to lower right corner direction from pressing screen position
The time interval at the second moment that the first moment of finger pressing screen collects user fingerprints with fingerprint Identification sensor is less than
Or during equal to preset duration, just carry out fingerprint authentication.12 are in current time:00 to 18:When 00, arrow b institutes in Fig. 8 are used
The mode shown carries out fingerprint authentication, i.e. terminal need to detect that the sliding trace direction of user's finger is downward from pressing screen position
Fingerprint Identification sensor is slid into, and the first moment of user's finger pressing screen collects user with fingerprint Identification sensor and refers to
When the time interval at the second moment of line is less than or equal to preset duration, fingerprint authentication is just carried out.18 are in current time:00
To 24:When 00, fingerprint authentication is carried out using the mode in Fig. 8 shown in arrow c, i.e. terminal need to detect the slip rail of user's finger
Mark direction is to slide into fingerprint Identification sensor in angular direction to left down from pressing screen position, and the of user's finger pressing screen
When the time interval at the second moment that one moment collected user fingerprints with fingerprint Identification sensor is less than or equal to preset duration,
Just carry out fingerprint authentication.
It is understood that the present embodiment can not only strengthen the security of fingerprint authentication, but also the execution of fingerprint authentication

For example, the machine that authentication module 304 will can prestore in the finger print information for the active user that collected and terminal
Main finger print information is compared.If determine that active user is owner by fingerprint comparison, then authentication module 304 can be right
Screen is unlocked operation, so that active user can be with this terminal of normal use.If determine currently to use by fingerprint comparison
Family is not owner, then authentication module 304 can not be unlocked screen, etc..
In one embodiment, the logging modle 302 can be used for：
If detecting, the electric signal in the predetermined inductive region changes, and obtains user's finger and presses the default sense
Answer the pressure value in region；
If detecting, the pressure value is in preset range, and the electric signal for recording the predetermined inductive region becomes
The first moment changed.
For example the screen of terminal is the screen with pressure sensitive, can perceive user's finger dub, flicking and again by
The difference of screen.In this case, the predetermined inductive region on user's finger pressing screen, causes predetermined inductive region
In screen back photosphere built-in test using capacitance sensor to electric current and magnitude of voltage change when, logging modle 302 can be same
When obtain user's finger and press the pressure value in the predetermined inductive region.
Then, logging modle 302 can detect whether the pressure value is in preset range.If so, then logging modle 302 can
To record the electric signal in the predetermined inductive region changed first moment.If it is not, then logging modle 302 can be without referring to
Line is verified.
For example, range of pressure values when above-mentioned preset range corresponds to user's finger flicking screen.That is, fingerprint authentication is held
Row condition is exactly the screen in requirement user elder generation flicking predetermined inductive region.That is, only when terminal detects user's flicking
During the screen in predetermined inductive region, logging modle 302 can just record the electric signal changed first in the predetermined inductive region
Moment.If a terminal detects that user dubs or again by the screen in predetermined inductive region, then it is default that terminal can not record this
Electric signal changed first moment of induction region, i.e. terminal will be without fingerprint authentication.

Exemplified by screen is held including display area 10 and non-display area 20, display area 10 is for showing the pictures such as word, image
Region, non-display area 20 are to know for placing front camera, receiver, ambient light sensor, proximity sensor and fingerprint
The region of individual sensor.Terminal can in advance by 10 bottom of display area on screen and account for display area area four/
One region is set as predetermined inductive region.Fingerprint Identification sensor is arranged on the non-display area 20 of terminal screen bottom.
In one embodiment, initial phase being configured, user can enter " setting " interface of terminal, and
First clicked on according to terminal notifying or flicking or again by the predetermined inductive region on screen, then press fingerprint Identification sensor, at the same time
Terminal can record the time point that user's finger touches predetermined inductive region, and user's finger presses fingerprint Identification sensor
Time point.Then, terminal can calculate the time interval at above-mentioned two time point, which is that user is default from touching
One sample value of the duration that induction region is spent to the process for touching fingerprint Identification sensor.It is understood that user
Aforesaid operations can be repeated several times, such determining module 305 can get multiple sample values.
After multiple sample values are got, determining module 305 can calculate the average value of the plurality of sample value.Then,
Determining module 305 can determine a preset duration according to the average value.The preset duration can represent under normal circumstances
User is from predetermined inductive region is touched to touching the duration that is spent required for fingerprint Identification sensor this process.
For example determining module 305 can obtain 5 sample values, and calculate the average value of this 5 sample values, Ran Houzai
Preset duration is determined according to the average value.For example, the average value can be determined as preset duration by determining module 305, alternatively,
Determining module 305 can also increase or decrease certain time length on the basis of the average value, obtain target duration, and by the target
Duration is determined as preset duration.
In another embodiment, the determining module 305 can be also used for：Obtain the facial image of user；According to
The facial image determines the age value of the user；According to the age value, target duration is obtained, and by the target duration
It is determined as preset duration.
For example determining module 305 does not get the sufficient amount of from predetermined inductive region is touched to touch fingerprint of user
The sample value for the duration that the process of identification sensor is spent, as determining module 305 only gets 1 sample value, then terminal
It will be unable to determine preset duration according to the average value of sample value.In this case, determining module 305 can also obtain user's
Facial image, and predict according to the facial image age value of the user.Then, it is determined that module 305 can according to predict come
Age value, obtain a target duration, and the target duration be determined as preset duration.
For example terminal can set corresponding duration for different age values in advance, and generate on age value and duration
Mapping table.So, after the age value of the user is determined according to the facial image of user, determining module 305 can
To inquire about the mapping table, and target duration corresponding with the age value of the user is therefrom obtained, then the target duration is true
It is set to preset duration.
For example, age value 1~10 when a length of 1.5 seconds, age value 11~40 when a length of 1 second, age value is 40
More than when a length of 1.3 seconds, etc..
