Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.
In conjunction with Fig. 1, it should be noted that the first application scenarios of the invention can be：
When gripping mobile terminal is unlocked operation, unlock operation can be exemplified as：By touch screen 11 input password,
Face is placed in the image acquisition region of camera 12 of mobile terminal by pattern, is asked with initiating unlock to mobile terminal
It asks.For mobile terminal when receiving the unlocking request, acquisition user holds the gripping data of mobile terminal；Then, number will be held
According to preset data (and can be described as reference data, such as：The custom data of mobile terminal are held before user) it compares, if
It holds data with reference data to match, is then determined as that user holds the unlock operation that mobile terminal carries out, and control shifting
Dynamic terminal in response to the unlocking request judge password input by user, pattern or the facial characteristics of user with pre-set it is close
Can the matching degree of code, pattern or facial characteristics by verification, if so, unlock.If gripping data at this time and reference number
According to not matching that, then it is determined as the unlock operation that non-user hand-held mobile terminal carries out, and indicate that mobile terminal refusal is rung
It should unlocking request.
The present invention second of application scenarios can be：
Difference lies in when receiving the unlocking request, allow mobile whole this application scene with the first application scenarios
End matches password input by user, pattern or the facial characteristics of user, and obtains matched result.But obtaining use
Either the facial characteristics of user and the password, pattern or the facial characteristics that pre-set match for the password of family input, pattern, hold
Before row unlock, then data will be held by needing matches with reference data, and movement is held eventually to determine whether user
The unlock operation that end carries out, if so, being unlocked；If it is not, not unlocking then.
It is understandable to be, in this application scene, obtaining password input by user, pattern or the facial characteristics of user
When not matched that with the password, pattern or facial characteristics pre-seted, then be not necessarily to determine whether my hand-held mobile terminal into
Capable unlock operation, refusal unlock.
In above two application scenarios, the matching either facial characteristics of the matching of password and password, pattern and pattern with
The matching of facial characteristics is more mature technology, therefore, no longer it is repeated herein.

The technical solution provided below in conjunction with attached drawing, each embodiment that the present invention will be described in detail.
Embodiment 1
Fig. 2 is a kind of flow diagram for unlocking request response method that the embodiment of the present invention 1 provides, referring to Fig. 2, the party
Method can specifically include following steps：
Step 22, when detecting unlocking request, the gripping data that confirmly detect, wherein the gripping data are used for
The holding operation application main body that description characterization carries out the mobile terminal is exactly mobile terminal；
In conjunction with above application scene, it should be noted that the first realization method of step 22 can be：
When mobile terminal is in screen lock state, if face is placed in the image acquisition areas of the camera of mobile terminal by user
In domain, then camera acquires the face-image (or facial feature data) of user, and shifting is sent in the form of unlocking request
The processor of dynamic terminal.Processor reads using the unlocking request as trigger condition and holds inductor currently collected data, make
For for characterize user currently hold mobile terminal holding operation and describe grip features gripping data (such as：It holds
Position, gripping dynamics etc.).
Second of realization method of step 22 can be：
When mobile terminal is in screen lock state, user inputs unlocking pin/pattern by touch screen to mobile terminal, with
Unlocking request is initiated, the processor of mobile terminal reads gripping inductor and currently collect using unlocking request as trigger condition
Data, as describe grip features (such as：Position, dynamics etc.) gripping data.
Wherein, holding inductor, currently collected data can be directly to react user's grip position, hold dynamics
Data；Or the data based on certain parameter indirect reaction user grip positions, gripping dynamics.Such as：Pressure sensor
As the one kind for holding inductor, the pressure value detected can directly react gripping dynamics, and antenna is as gripping inductor
One kind, the parameter value of characterisitic parameter can be with indirect reaction grip position.
Step 24 judges whether the gripping data and preset data match；
If so, thening follow the steps 26；If it is not, it is then not responding to the unlocking request, and end step.
It should be noted that the first realization method of step 24 can be：
Custom before holding the user that data are obtained with training is held data (reference data) to match, judges two
Whether person matches, if so, determination is the unlocking request that the user carries out in gripping mobile terminal.
Second of realization method of step 24 can be：
Corresponding unlock type is determined based on unlocking request, such as：Face unlock, password unlock, pattern unlock, based on solution
Lock type finds out corresponding reference data from pre-established reference database, has unlock type in the reference database
Correspondence between reference data；Then, data will be held to match with corresponding reference data, and will be with both judgements
It is no to match.
It is understandable to be for second of realization method, when user is unlocked based on different unlock types, hold
Great changes have taken place for the mode possibility for the mobile terminal held, such as：When password unlocks, user may need to be inputted with thumb close
Code, therefore, thumb is discontiguous with mobile terminal；And when face unlock, user is without being manually entered password, therefore, generally
It is 5 finger righting mobile terminals to be directed at face.As it can be seen that password unlock gripping data corresponding with facial unlock exist
Therefore larger difference is highly desirable that corresponding reference data is arranged to different types of unlocking manner respectively, with further
Improve unlock precision and safety.
Step 26, the response unlocking request.
Understandable to be, when holding data and reference data matches, then judgement is that user holds movement eventually
The unlocking request initiated is held, therefore, mobile terminal carries out the operation of verification unlocking request in response to unlocking request, if by testing
Card, then unlock success.
In addition, when holding data and reference data does not match that, then judgement is that non-user holds mobile terminal hair
The unlocking request risen, mobile terminal refusal respond unlocking request.
As it can be seen that the present embodiment is by when detecting unlocking request, determining the gripping data for holding mobile terminal, and will hold
It holds data to be matched with reference data, to determine whether that user holds the mobile unlocking request initiated eventually, and true
Surely it is after user holds mobile terminal, mobile terminal responds the unlocking request, avoids the occurrence of the progress of non-user subjective desire
Malice unlock the case where, can realize improve unlock safety purpose.

Office can be each antenna in upper and lower, left and right, respective antenna B42, antenna A41, antenna C43, antenna D44.
It should be understood, of course, that either using the scheme of two antennas or the scheme of four antennas, even
The scheme of other antenna arrangement modes can realize the purpose of the present embodiment based on the principle in step 1, but in order to ensure to instruct
The hand-held custom data of the user practised have higher precision, use the scheme of each antenna in upper and lower, left and right herein.
It is corresponding, it is recorded as in the characterisitic parameter (standing wave, impedance etc.) of free state each antenna (under non-holding state)：
Antenna A：A0；
Antenna B：B0；
Antenna C：C0；
Antenna D：D0；
Antenna parameters are mapped as hand-held custom data：{ A0, B0, C0, D0 }
Step 3: determining hand-held custom data when user holds first position
It should be noted that user is holding mobile terminal so that camera energy normal photographing facial characteristics generate unlock letter
Breath or when payment information, since the size of its hand, the position held are relative to the source of each antenna and the difference of terminal position,
Therefore, different antenna characterization informations will be generated.Wherein, the source of antenna A41 and end are denoted as 411 and 412, antenna respectively
The source of B42 and end are denoted as 421 and 422 respectively, and the source of antenna C43 and end are denoted as 431 and 432 respectively, antenna D44's
Source and end are denoted as 441 and 442 respectively.
Fig. 4 b are participated in, when user holds mobile terminal close to source position (position on the lower side of terminal) of antenna A, C, D, institute
Switching antenna characterisitic parameter (standing wave, impedance etc.) is held to be recorded as：
Antenna A：A1；
Antenna B：B1；
Antenna C：C1；
Antenna D：D1；
The parameter value of antenna parameters is mapped as hand-held custom data：{ A1, B1, C1, D1 }.
Step 4: determining hand-held custom data when user holds the second position
Participate in Fig. 4 c, at centre position (centre of terminal) of user's grip position close to antenna C, D, held state
Antenna parameters (standing wave, impedance etc.) are recorded as：
Antenna A：A2；
Antenna B：B2；
Antenna C：C2；
Antenna D：D2；
The parameter value of antenna parameters is mapped as hand-held custom data：{ A2, B2, C2, D2 }.
Step 5: the step of determining hand-held custom data is repeated, and using determining hand-held custom data as sample
It is trained and tests
Based on the principle for the hand-held custom data of determination that step 3 and step 4 describe, scheduled duration/number is persistently recorded
Hand-held custom data；Then, by the hand-held custom data of part：{ A1, B1, C1, D1 }~{ Ax, Bx, Cx, Dx } is as training
Sample builds the second reference data based on scheduled training pattern.By the hand-held custom data of itself and part：{Ax1, Bx1, Cx1,
Dx1}、{Ax2, Bx2, Cx2, Dx2Or { Ax3, Bx3, Cx3, Dx3 } etc. be used as test sample, test the second reference data.
It trains and the first realization method for testing the second reference data can be：
Based on training sample { A1, B1, C1, D1 }~{ Ax, Bx, Cx, Dx }, the corresponding characterisitic parameter of each antenna is determined
Value range, such as：{ A2~A8, B3~B5, C1~C9, D11~D20 }, as the second reference data；Then, judge to test
Whether the parameter value of the characterisitic parameter in sample is located in value range, passes through verification according to what judging result determined test sample
Percent of pass, and based on percent of pass correct the second reference data.
It trains and second of realization method for testing the second reference data can be：
Based on training sample { A1, B1, C1, D1 }~{ Ax, Bx, Cx, Dx }, one group of higher data of the degree of polymerization, example are determined
Such as：{ A3, B5, C8, Dx }, as the second reference data；Then, the corresponding data of contrast test sample and the second reference data it

The second reference data is corrected in percent of pass.
In this realization method, the similarity calculation between the polymerizations of data, data and data belongs to more mature existing
Technology, details are not described herein again.
In addition, as preferred realization method, the present embodiment can also update the second reference data according into Mobile state, until
Data stabilization, to improve accuracy.Since the parameter collection during this, terminal training, terminal study are all on terminal backstage
It carries out, therefore, does not interfere with the normal use of user.
Step 6: the hand-held custom data that application training is good
Referring to Fig. 4 d, holds mobile terminal in non-owner and carry out malicious operation, so that user's face position mobile terminal
When image acquisition region, hold data inevitably can have more apparent difference with the hand-held custom data of user (owner),
Such as：The grip position that everyone holds mobile terminal has differences.
Such as：Non- owner holds mobile terminal close to the position of antenna A, B, C, D, the switching antenna characterisitic parameter (standing wave,
Impedance etc.) it is recorded as：
Antenna A：Afail；
Antenna B：Bfail；
Antenna C：Cfail；
Antenna D：Dfail；
Correspondingly, the hand-held custom data of the non-owner of mapping：{Afail, Bfail, Cfail, Dfail, as to be verified
One holds data, to characterize the grip position that non-owner holds mobile terminal.Data and second in step 5 are held by first
Reference data is compared, it is known that the two will have larger difference, hence it is evident that distinguishes over the hand-held custom of owner.
Second reference data and test in the realization method and step 5 of the first gripping data of comparison and the second reference data
The way of contrast of sample is similar, such as：The value range (A3~A8) for the corresponding standing waves of antenna A that training is completed, with gripping
The standing wave A that antenna A is detected in datafailIt is compared, determines AfailWhether (A3~A8) is belonged to, if so, determining the two phase
Matching.Similarly, other antennas can be corresponded to the value range of standing wave respectively with Bfail、Cfail、DfailIt is compared.If all phases
Match, it is determined that hold data and match with reference data.Optionally, if without all match and departure degree within a predetermined range,
It is also contemplated that the two matches.Therefore no longer it is repeated herein.
With it is above-mentioned similar about individual antenna characterisitic parameter-matching rule of standing wave, for mutiple antennas characterisitic parameter
Matching rule, briefly：The corresponding reference data of each antenna parameters can be first found out from the presets list,
Then the corresponding gripping data of each antenna parameters confirmly detected, and it is carried out one with the reference data found out
One comparison, to obtain the corresponding matching result of other each antenna parameters, and then can be from the dimension of multiple antennas characterisitic parameter
Determine whether hold data and reference data matches.
Example two, by inductor be pressure sensor for
Step 1: the layout of the pressure sensor of mobile terminal is described in detail
Layout type 1, referring to Fig. 5 a, mobile terminal includes a pressure sensor group, and the pressure in pressure sensor group passes
Sensor is set to the side of the mobile terminal, and left and right side, this is sentenced for left side.
Layout type 2, referring to Fig. 5 b, mobile terminal includes first pressure sensor group and second pressure sensor group,
Pressure sensor in one pressure sensor group is set to the first side (by taking left side as an example) of the mobile terminal, and second pressure passes
Pressure sensor in sensor group is set to the second side of the mobile terminal (by taking right side as an example).
For above two layout type, the quantity of pressure sensor is exemplified as：Each pressure sensor group has 21 pressures
Force snesor, correspondingly, the number of the pressure sensor in first pressure sensor group is once A1, A2 ... A21 from top to bottom,
The number of pressure sensor in second pressure sensor group is once B1, B2 ... B21 from top to bottom；Moreover, pressure sensor
The entire side for spreading all over mobile terminal is can be set to, empirical value can also be based on, pressure sensor is set to user's gripping
In the range of easy gripping is arrived when mobile terminal is unlocked operation.It is described in detail by taking layout type 2 as an example below：
Correspondingly, the records of values for two groups of pressure sensors being recorded under the non-holding state of free state is：
First group of pressure sensor：A10A20A30~A210
Second group of pressure sensor：B10B20B30~B210
In turn, pressure sensor is mapped as the hand-held custom data of user：{A10A20A30~A210, B10B20B30~
B210}。
Step 2: determining hand-held custom data when user holds first position
When user holds mobile terminal so that camera energy normal photographing facial characteristics generate unlocking information or payment information,
Since the size of its hand, institute's grip pressure force snesor position difference pressure sensor will obtain different pressures data.
When user is held in the first position shown in Fig. 5 c, each pressure sensor pressure value is recorded as：
Pressure sensor A：A11A21A31~A211
Pressure sensor B：B11B21B31~B211
In turn, mapping obtains the hand-held custom data of user：{A11A21A31~A211, B11B21B31~B211}。
Step 3: determining hand-held custom data when user holds the second position
When user is held in the second position (close to the middle and lower part of mobile terminal) shown in Fig. 5 d, each pressure sensor pressure
Force value is recorded as：
Pressure sensor A：A12A22A32~A212
Pressure sensor B：B12B22B32~B212
In turn, mapping obtains the hand-held custom data of user：{A12A22A32~A212, B12B22B32~B212}
Step 4: the step of determining hand-held custom data is repeated, and using determining hand-held custom data as sample
It is trained and tests
Based on the step 2 step similar with step 3, the pressure data of scheduled duration/number is acquired, and it is more to map acquisition
The hand-held custom data of group.Then, using some of hand-held custom data as training sample, one group of extent of polymerization is trained
Highest hand-held custom data, alternatively, build the corresponding pressure limit of each pressure sensor, as the first reference data, with
Grip position when position based on pressure sensor and the pressure value characterization user detected hold mobile terminal and curable grip
Degree, this process is similar to step 5 in example one, therefore, details are not described herein again.Then, made with the hand-held custom data of remainder
The reference data trained is tested for test sample, is corrected, until meeting scheduled measuring accuracy.
Step 6: the first reference data that application training is good
Mobile terminal is held in non-owner and carries out malicious operation, so that the image acquisition areas of user's face position mobile terminal
When domain, hold data inevitably can have more apparent difference with the hand-held custom data of user (owner).
Referring to Fig. 5 e, non-owner is recorded as in the third place, then held state pressure sensor：
Pressure sensor A：A1failA2failA3Fail~A21fail
Pressure sensor B：B1failB2failB3Fail~B21fail
In turn, to be verified second mapped out holds data：{A1failA2failA3Fail~A21fail,
B1failB2failB3Fail~B21fail, with based on pressure sensor position and pressure sensor detect pressure value characterization it is non-
Owner user holds the grip position and the dynamics of gripping when mobile terminal.
Second gripping data to be verified are compared with the first reference data, you can know that the two has larger difference
It is different, and then determine that this unlock operation is that non-owner initiates.
Wherein, the first realization method of the second gripping of comparison data and the first reference data can be：
Data are held by described second and first reference data compares, and are obtained described second and are held data and institute
State the similarity between the first reference data；Judge that described second holds the similarity between data and first reference data
Whether predetermined similarity threshold is met；If not, it is determined that it is described second gripping data and first reference data do not match that,
And then determine that this unlock operation is that non-owner initiates；If so, determining that described second holds data and first ginseng
Data match is examined, and then determines that this unlock operation is what owner initiated.
For the first realization method, it should be noted that second holds the comparison between data and the first reference data,
Prior art progress can be used due to specifically comparing scheme in comparison between actually one group of data and another group of data,
Therefore, no longer its concrete methods of realizing is defined herein.
Comparing second of realization method of the second gripping data and the first reference data can be：
Number based on pressure sensor holds the pressure that each pressure sensor carried in data detects by first
Value, the pressure limit of each pressure sensor corresponding with the first reference data is compared respectively；Determine whether each pressure
The pressure value that sensor detects is both fallen in corresponding pressure limit, alternatively, whether error is held within a predetermined range, if so,
It then determines that the two matches, and then determines that this unlock operation is owner's initiation.
Based on above two example, when opening face recognition, the detection of hand-held custom is added, as identification condition.With
Pressure inductor data learn the reference data to be formed with the above terminal when family operates, and do algorithm process and carry out matching comparison,
When in scheduled difference range, receive face recognition, not in this range when, then refuse face recognition, to avoid owner from existing
Under the person is limited or other non-autonomous unlock scenes, other people hand-held set master mobile terminals are stolen owner by face recognition and are believed
The case where breath or fund, improves the safety of face recognition unlock.
