Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
It is described in detail to one step, it is clear that the described embodiments are only some of the embodiments of the present invention, rather than whole implementation
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
All other embodiment, shall fall within the protection scope of the present invention.
Mobile terminal in the embodiment of the present invention can be smart phone, tablet computer etc. with motion sensor.
In the prior art, the identification of user identity is usually to pass through account and password check, the certification such as short-message verification message
What mode was realized, but due to the opening of network, the maximum drawback of this mode is exactly that password is easy leakage, especially works as password
When fairly simple, the case where known people can even guess out, therefore account or password are illegally usurped, is often occurred.In order to protect
Card safety, it is often necessary to which multiple passwords are protected simultaneously, increase the complexity of subscriber authentication.
Biometrics use physiological characteristic (such as fingerprint, palmmprint, face, iris) specific to everyone as it
Or behavioural characteristic (such as person's handwriting, keystroke etc.), and these features largely have uniqueness and non-imitability, greatly
Reduce the risk that user is acted as fraudulent substitute for a person.
The difference of different whippings habit and personal character when due to different people Wrist-sport, so that everyone gets rid of in wrist
Oneself unique motion mode is respectively formed when dynamic, therefore the motion feature of mobile phone can represent user identity.The embodiment of the present invention
Based on the description to mobile phone motion feature that motion sensor in mobile terminal exports, a kind of User reliability authenticating party is provided
Method,
The embodiment of the invention provides a kind of User reliability authentication methods, and the process of this method is as shown in Figure 1, method can
To include the following steps：
S101, the first motion profile for obtaining mobile terminal, first motion profile are that user holds the mobile terminal
Do the track of regular motion；
S102, first motion profile and preset verifying motion profile are compared, if first motion profile
Similarity with the verifying motion profile is more than first threshold, then judges that the user is credible.
Since the hand and wrist of different people are when carrying out action of writing, habit firmly is different, therefore mobile terminal is in sky
Between in motion profile there is specific motion feature, the motion feature of different person writings is different, thus can use it is mobile eventually
The motion profile at end is as the foundation for differentiating different user.
In the embodiment of the present invention, when needing the confidence level to mobile terminal user to authenticate, it is desirable that user holds movement
Terminal does regular motion, the letter as defined in the writing of single-hand handling & mobile phone.The track of regular motion is obtained, and using the track as the
One motion profile compares with preset verifying motion profile, and verifying motion profile is that the trusted users of mobile terminal create simultaneously
Storage, if the similarity of the first motion profile and verifying motion profile more than first threshold, judges the user and can credit
Family is the same person, i.e., the user is credible, can carry out subsequent operation.It is with the writing of user itself in the embodiment of the present invention
Feature is used as according to confidence level certification is carried out, and is avoided password in the prior art and is easy to reveal and existing security risk.And it uses
Family need to only hold mobile terminal and carry out a regular motion in certification, convenient and efficient, avoid the need for inputting a variety of passwords
Complicated processes.Further, since all having motion sensor in existing overwhelming majority mobile terminal, can support of the invention real
The authentication method of example is applied, therefore is not required to additionally increase apparatus module, is reduced costs, there is versatility.
Verifying motion profile in step S102 can obtain in the following manner：
The second motion profile at least twice of the mobile terminal is obtained, second motion profile is that user holds the shifting
Dynamic terminal does the track of the regular motion；
Second motion profile at least twice is compared, if the similarity of second motion profile at least twice is super
Second threshold is crossed, then is moved any second motion profile in second motion profile at least twice as preset verifying
Track.
I.e. before step S101, user holds the regular motion of mobile terminal progress at least twice, and at least twice by this
The track of regular motion compares, will be any if the similarity of the track being compared between any two is all satisfied requirement
Motion profile is saved as verifying motion profile as the verifying whether believable foundation of user.
Motion profile is compared and mainly compares the motion profile of turning point in motion profile, because different
For user when hand-held mobile terminal is write, the feature of the motion profile of stroke turning point is more distinct.If by everyone
The amplification action that hand-held mobile phone is write, it is found that everyone motion profile in stroke turning point is impossible to be absolute straight
Line, but the curve of different radian, as " N " alphabetical in Fig. 2 from " | " to " " track, be to be linked to be by the curve of certain radian
's.This inconsistent feature of the processing of different people transition location can be used as foundation to distinguish different user.
Therefore, it in the embodiment of the present invention, motion profile will compare twice in the following manner, including：
Obtain the radian of the first motion profile of the mobile terminal；
If there are the motion profiles that radian is greater than third threshold value in first motion profile, it is determined that first movement
There is turnover in track；
By the motion profile of the turning point of first motion profile turning point corresponding with the verifying motion profile
Motion profile compares.
Specifically, regular motion need to include no less than 5 turnovers in the embodiment of the present invention, such as can specify that regular motion
" NZ " is write in the sky as shown in the track in Fig. 2 for user's cell phone, then obtains 5 turnovers in the track " NZ ".
It should be noted that the writing style of different users is possible to different when user writes " NZ " in the sky, such as
When some users write " N ", the first stroke " | " is by down toward upper writing, some users are from top to bottom to write；User's book also
The first stroke of the finishing touch of writing " N " and " Z " be it is coherent, user be incoherent.No matter the writing style of user such as
What, motion sensor can recognize that the motion profile of turning point when the mobile phone moves in the sky, and the same user writes
Motion profile is identical, therefore can be used as the foundation of user identity authentication.
That user holds that mobile phone writes out is " NZ ", but in the mobile phone motion profile that identifies of motion sensor, " N's " is last
The first stroke of one and " Z " be in fact it is coherent, as Fig. 2 03 circle in dotted line shown in, as seen from Figure 2, the movement rail
Mark includes 01-05 totally 5 turnovers.According to the radian for the motion profile that motion sensor is measured, biggish radian is turnover
Position, the motion profile of 5 turning points is opposite with the motion profile of 5 turning points of the verifying motion profile " NZ " prestored
Than.In addition, if the writing style of user is the first stroke " | " for writing " N " from top to bottom, then user writes second of " N "
" " when, mobile phone need to be moved to the top position of " | ", then the movement of lower right obliquely downward from the lower position of " | ".To which movement passes
Sensor can measure two turnovers in the process, and along with subsequent 4 turnovers, one is 6 turnovers, meet at least five and turn
The condition of folding.It at this time can be by the fortune of the motion profile of this 6 turning points and 6 turning points of the verifying prestored motion profile
Dynamic rail mark compares.By parity of reasoning, the habit regardless of user's writing " NZ ", and the turnover that motion sensor is measured is both greater than etc.
In 5.Due to the writing style of user be it is constant, the track of at least five turning point in motion profile can be made
For the foundation of comparison.
Further, the similarity between the first motion profile and verifying motion profile is determined by following manner：
At least one first orbit segment is determined from first motion profile, and from the verifying motion profile
Determine at least one second orbit segment, wherein each first orbit segment is the motion profile of turning point, each described
Two orbit segments are the motion profile of turning point；
The first orbit segment and the second orbit segment are grouped according to the position of place motion profile, wherein having one in every group
A first orbit segment and second orbit segment, the first orbit segment in a group is in the position and the of first motion profile
Two orbit segments are identical in the position of the verifying motion profile；
The first orbit segment in every group is compared respectively with the second orbit segment, determines that similarity is more than the group of the 4th threshold value
Quantity, and moved the ratio of determining quantity and the quantity of the first orbit segment as first motion profile and the verifying
The similarity of track.
Specifically, determine that N number of orbit segment, N number of orbit segment are respectively positioned on the first motion profile in the first motion profile
In turning point, be denoted as the first orbit segment；N number of orbit segment is also determined in verifying motion profile, also is located at verifying motion profile
In turning point, be denoted as the second orbit segment.N number of first orbit segment and N number of second orbit segment are compared into similarity, wherein comparing
The first orbit segment it is identical in position of position and the second orbit segment in the first motion profile in verifying track, i.e., by the 1st
A first orbit segment and the 1st the second orbit segment compare, the 2nd the first orbit segment and the 2nd the second orbit segment comparison ... N
A first orbit segment and the second orbit segment of n-th compare.It compares in the N number of similarity obtained, having M similarity is more than the 4th threshold
Value, then M/N is the similarity of the first motion profile and verifying motion profile, i.e. the quantity of orbit segment that meets the requirements of similarity
The ratio of the quantity of total orbit segment is accounted for, is the similarity of two motion profiles, wherein the quantity of N is bigger, as a result more accurate.
Since the orbit segment compared is located at the turning point of motion profile, the method for obtaining the first orbit segment is,
First motion profile is divided into multiple orbit segments；According to the radian of each orbit segment of division, from multiple orbit segments
Determine the first orbit segment.Similarly, the method for obtaining the second orbit segment is that the verifying motion profile is divided into multiple tracks
Section；According to the radian of each orbit segment of division, the second orbit segment is determined from multiple orbit segments.
Specifically, i.e., the first motion profile is divided into P orbit segment, in order to keep result more acurrate, the quantity of division
Can be more as far as possible when conditions permit, i.e., P is bigger, and it is as a result more accurate, but calculation amount is also bigger.In P orbit segment
In, determine N number of orbit segment of turning point, since the motion profile of turning point is camber line, can be according to each orbit segment
Radian, i.e., radian be greater than certain certain value orbit segment be the first orbit segment, thus can get N number of first orbit segment.Similarly, may be used
To determine N number of second orbit segment.
Mobile-terminal simulator carries out information stealth to forge mobile terminal in order to prevent, because not moving in simulator
Sensor, therefore, the embodiment of the present invention further includes before step S101：Obtain the gyroscope model of the mobile terminal；Root
According to the gyroscope model of the mobile terminal, terminal iidentification is generated；The terminal iidentification and preset verifying mark are compared,
If consistent, the step of executing the first motion profile for obtaining mobile terminal.The success of gyroscope model is obtained if can be seen that,
Then illustrate that mobile terminal is not simulator, subsequent operation can be continued；Otherwise it is assumed that the mobile terminal is dangerous.It can be with
The model of gyroscope is converted into hexadecimal character string, generates terminal iidentification after making a summary to the character string.
Further, the embodiment of the present invention also obtains mobile terminal while obtaining the gyroscope model of mobile terminal

Number, the information such as the model of linear acceleration sensors, it is similar to the processing mode of gyroscope model, by above- mentioned information and gyroscope
Sensor model number is arranged by regulation sequence, and is converted to hexadecimal character string, and generating after making a summary to the character string should
The ID of mobile terminal.The ID of generation is compared with pre-stored ID, if unanimously, illustrate the confidence level of the mobile terminal compared with
Greatly, subsequent operation can be carried out；Otherwise it is assumed that the safety of the mobile terminal is smaller.
In the embodiment of the present invention, the method that two orbit segments compare used is indicated to establish coordinate system with equation
Different tracks section, then the coefficient in equation is compared, using the result of index contrast as judging two orbit segment similarity degrees
Foundation.It is described in detail by taking smart phone as an example below.
Specifically, the acquisition and comparison of motion profile can be carried out in the following manner：
1, user is guided to operate on mobile phone.
1.1, prompt user inverts the long side of mobile phone, makes mobile phone perpendicular to ground.
1.2, prompt user only uses any position of a finger contact handset touch panel, usually thumb, and records
The position that lower user's finger is pressed.
1.3, prompt user holds mobile phone and writes " NZ " in the sky.
2, the data of motion sensor measurement in mobile phone motion process are collected.
Motion sensor in smart phone is divided into linear acceleration sensors and gyro sensor, can experience acceleration
It spends and is converted into usable output signal.
2.1, coordinate system is established：Centered on the position that user's finger is pressed on handset touch panel because mobile phone be
Perpendicular to moving in the plane on ground, the direction for being parallel to ground side-to-side movement using mobile phone moves up and down as X-axis perpendicular to ground
Direction be Y-axis, perpendicular to mobile phone plane of movement direction be Z axis, establish coordinate system, as shown in Figure 3.
2.2, data collection sampling：Determine that the tracing point on motion profile as sampled point, and passes through fortune using certain frequency
The exercise data of the dynamic each sampled point of sensor measurement.In the embodiment of the present invention, measured using linear acceleration sensors each
The acceleration of the XY axial plane of sampled point, gyro sensor measure the acceleration of XZ axial plane and the arc of each sampled point
Degree, wherein because the acceleration of gravity of each region is different, therefore all acceleration do not include acceleration of gravity, avoid weight
Error caused by power acceleration.
Specifically, the acceleration along X-axis that linear acceleration sensors are measured is LX, the acceleration along Y-axis is LY；Top
The acceleration along X-axis that spiral shell instrument sensor is measured is AX, the acceleration along Z axis is AZ, the unit of above-mentioned acceleration is m/s2。
Meanwhile obtaining the sampling time T of each sampled point.
3, data are analyzed.
3.1 choose the sampled point of turning point：According to the radian for each sampled point that gyro sensor is measured, judge that this is adopted
Whether sampling point is located at turning point, and the sampled point that radian is greater than threshold value is taken out, calculating analysis is carried out.
3.2, the line segment equation between neighbouring sample point is established：
By taking XY axis coordinate system as an example, i.e., motion profile is projected in the plane where XY axis, take two adjacent samplings
Point a and sampled point b, then coordinate of the sampled point b in XY axis coordinate system be respectively：
Xb=Xa+LXa(Tb-Ta)2... ... ... ... ... ... ... ... ... formula (1)
Yb=Ya+LYa(Tb-Ta)2... ... ... ... ... ... ... ... ... ... formula (2)
Wherein, XaAnd YaX axis coordinate and Y axis coordinate of the respectively a point in XY axis coordinate system, XbAnd YbRespectively b point exists

The acceleration for the b point that property acceleration transducer is measured, TaFor the sampling time of a point, TbFor the sampling time of b point.
According to formula 1 and formula 2, the coordinate of all sampled points can be calculated in motion profile.Due in motion profile
Sampled point quantity it is very big, therefore the line between two sampled points of arbitrary neighborhood can be approximated to be straight line, therefore, can be according to adjacent
The coordinate of two sampled points establishes the linear equation between sampled point, and each motion profile can establish P straight line side as a result,
Journey is denoted as Y=kQ× X (3), wherein kQTherefore P coefficient k can be calculated for the coefficient of the Q linear equation.
P coefficient k in first motion profile is divided by with P coefficient k in verifying motion profile, is denoted as SP=kiP÷
kjP(4), wherein kiPFor the coefficient of the linear equation of each orbit segment in the first motion profile, kjPIt is each in verifying motion profile
The coefficient of the linear equation of a orbit segment, SPFor the P rail in the P orbit segment in the first motion profile and verifying motion profile
The similarity of mark section.
The similarity degree for indicating two motion profiles with 0~1,1 indicates that two motion profiles are identical, and 0 indicates two
Motion profile is entirely different.By the S of numerical value in a certain rangePCorresponding orbit segment is determined as effective orbit segment, for example, will count
The S being worth between 95% to 105%PIt is denoted as SEffectively, in the first motion profile the quantity of effective orbit segment of some turning point with
The ratio of the sum of the orbit segment of the turning point, the as motion profile of the turning point of the first motion profile and verifying movement rail
The similarity of the motion profile of the corresponding turning point of mark, i.e.,：Similarity=SEffectively÷SSum(5)。
The similarity of first motion profile and verifying motion profile is being averaged for the motion profile similarity of all turning points
Value.
Similarly, motion profile projects in the plane where XZ axis, i.e., in XZ axis coordinate system, the first motion profile with test
The similarity of card motion profile is also calculated according to such as above-mentioned identical mode.
Only the first motion profile and verifying motion profile in the similarity of two planes are all satisfied requirement, just can determine that the
The similarity of one motion profile and verifying motion profile is met the requirements, that is, is verified.For example, the first motion profile and verifying are transported
Dynamic rail mark is all larger than 95% in the similarity of two planes, then judgement is verified.
Similarly, it if user is the preset verifying motion profile of creation, needs to hold mobile terminal writing at least twice " NZ ".Such as
Regulation need to write " NZ " three times, and the mutual similarity of this motion profile for writing three times is above 90%, then it is assumed that verifying
Motion profile creates successfully, appoints and a motion profile is taken to be saved as preset verifying motion profile.
For a clearer understanding of the present invention, above-mentioned process is described in detail with specific example below.The specific reality
