Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Mobile terminal in the embodiment of the present invention can be the smart mobile phone, panel computer etc. with motion sensor.
In prior art, the identification of user identity is normally by account and cryptographic core pair, the authentication modes such as short-message verification message realize, but due to the opening of network, the maximum drawback of this mode is exactly that password is easily revealed, especially when password is fairly simple, familiar people even can guess out, and therefore account or password are often had generation by situation about illegally usurping.In order to ensure safety, usually needing multiple password to protect simultaneously, adding the complexity of subscriber authentication.
Biometrics uses physiological characteristic specific to everyone (as fingerprint, palmmprint, face, iris etc.) or behavioural characteristic (as person's handwriting due to it, keystroke etc.), and these features have uniqueness and non-imitability to a great extent, considerably reduce user by the risk acted as fraudulent substitute for a person.
Due to whippings different during different people Wrist-sport custom and the difference of personal character, make everyone all define the motion mode of oneself uniqueness when wrist whipping, therefore the motion feature of mobile phone can representative of consumer identity.The description to mobile phone motion feature that the embodiment of the present invention exports based on motion sensor in mobile terminal, provides a kind of User reliability authentication method,
Embodiments provide a kind of User reliability authentication method, as shown in Figure 1, method can comprise the steps: the flow process of the method
First movement locus of S101, acquisition mobile terminal, described first movement locus is the track that user holds that described mobile terminal does regular motion;
S102, by described first movement locus with preset checking movement locus compare, if the similarity of described first movement locus and described checking movement locus exceedes first threshold, then judge that described user is credible.
Because the hand of different people and wrist are when carrying out action of writing, custom is firmly different, therefore mobile terminal movement locus in space has specific motion feature, the motion feature that different people is write is different, and the movement locus of mobile terminal therefore can be utilized as the foundation differentiating different user.
In the embodiment of the present invention, when needing to carry out certification to the confidence level of mobile phone users, require that user holds mobile terminal and does regular motion, as the letter of regulation write by single-hand handling & mobile phone.Obtain the track of regular motion, and using this track as the first movement locus, compare with the checking movement locus preset, checking movement locus is that the trusted users of mobile terminal creates and stores, if the first movement locus exceedes first threshold with the similarity of checking movement locus, then judge that this user and trusted users are same persons, namely this user is credible, can carry out subsequent operation.In the embodiment of the present invention, be using the writing feature of user self as according to carrying out confidence level certification, avoid password in prior art and easily reveal and the potential safety hazard that exists.And user is when certification, only need hold mobile terminal carries out a regular motion, convenient and swift, avoids the complicated processes needing to input multiple password.In addition, owing to all there is motion sensor in existing most mobile terminal, the authentication method of the embodiment of the present invention can be supported, therefore not need additionally to increase apparatus module, reduce cost, there is versatility.
Checking movement locus in step S102 can obtain in the following manner:
Obtain at least twice second movement locus of described mobile terminal, described second movement locus is the track that user holds that described mobile terminal does described regular motion;
Described at least twice second movement locus is compared, if the similarity of described at least twice second movement locus exceedes Second Threshold, then using arbitrary second movement locus in described at least twice second movement locus as preset checking movement locus.
Namely before step S101, user holds the regular motion that mobile terminal carries out at least twice, and the track of this at least twice regular motion is compared, if the track compared similarity between any two all meets the demands, then will wherein as checking movement locus, namely preserve as the whether believable foundation of authentication of users by arbitrary movement locus.
Carried out contrasting by movement locus and mainly contrasted by the movement locus of turning point in movement locus, because different user is when hand-held mobile terminal is write, the feature of the movement locus of stroke turning point is more distinct.If the action of being write by everyone handheld mobile phone is amplified, can find that everyone movement locus in stroke turning point can not be absolute straight line, but the curve of different radian, as in Fig. 2 letter " N " from " | " to " " track, be linked to be by the curve of certain radian.Process this feature inconsistent of different people transition location, can distinguish different user as foundation.
Therefore, in the embodiment of the present invention, in the following manner twice movement locus is compared, comprising:
Obtain the radian of the first movement locus of described mobile terminal;
If there is the movement locus that radian is greater than the 3rd threshold value in described first movement locus, then determine there is turnover in described first movement locus;
The movement locus of turning point corresponding with described checking movement locus for the movement locus of the turning point of described first movement locus is compared.
Specifically, in the embodiment of the present invention, regular motion need comprise and be no less than 5 turnovers, and as specified, regular motion is user's cell phone, as shown in the track in Fig. 2, aloft writes " NZ ", then obtains 5 turnovers in " NZ " track.
It should be noted that, when user aloft writes " NZ ", the writing style of different users is likely different, than if any user writing " N " time, the first stroke " | " for by down on write, some users are for from top to bottom to write; The finishing touch of user writing " N " also had and the first stroke of " Z " are coherent, and some users are incoherent.Regardless of the writing style of user, motion sensor all can identify the movement locus of turning point when this mobile phone moves aloft, and the movement locus of same user writing is identical, therefore can as the foundation of authenticating user identification.
That user's handheld mobile phone writes out is " NZ ", but in the mobile phone movement locus that motion sensor identifies, the finishing touch of " N " and the first stroke of " Z " are coherent in fact, as shown in the dotted line in 03 circle of Fig. 2, as seen from Figure 2, this movement locus comprises 01-05 totally 5 turnovers.According to the radian of the movement locus that motion sensor is measured, the position of turnover that what radian was larger be, compares the movement locus of the movement locus of 5 turning points with 5 turning points of the checking movement locus " NZ " prestored.In addition, if the writing style of user is the first stroke " | " writing " N " from top to bottom, so user writing " N " second " " time, mobile phone need be moved to the top position of " | " from the lower position of " | ", then bottom right tiltedly below is mobile.Thus motion sensor can measure two turnovers in the process, add 4 turnovers below, one is 6 turnovers, meets the condition of at least 5 turnovers.Now just the movement locus of the movement locus of these 6 turning points with 6 turning points of the checking prestored movement locus can be compared.By parity of reasoning, and regardless of the custom of user writing " NZ ", the turnover that motion sensor is measured all is more than or equal to 5.Writing style due to user is constant, therefore, and can by the track foundation as a comparison of a turning point, at least 5 in movement locus.
Further, the similarity between the first movement locus and checking movement locus is determined by with under type:
At least one first orbit segment is determined from described first movement locus, and at least one second orbit segment is determined from described checking movement locus, wherein each described first orbit segment is the movement locus of turning point, and each described second orbit segment is the movement locus of turning point;
First orbit segment and the second orbit segment divide into groups by the position according to place movement locus, wherein often have first orbit segment and second orbit segment in group, the first orbit segment in a group is identical in the position of described checking movement locus with the second orbit segment in the position of described first movement locus;
The first orbit segment in every group and the second orbit segment are contrasted respectively, determine the quantity of similarity more than the group of the 4th threshold value, and using the similarity of the ratio of the quantity of the quantity determined and the first orbit segment as described first movement locus and described checking movement locus.
Specifically, in the first movement locus, determine N number of orbit segment, this N number of orbit segment is all arranged in the turning point of the first movement locus, is designated as the first orbit segment; In checking movement locus, also determine N number of orbit segment, be also arranged in the turning point of checking movement locus, be designated as the second orbit segment.N number of first orbit segment and N number of second orbit segment are contrasted similarity, with the second orbit segment, the position of the first orbit segment wherein compared in the first movement locus is verifying that the position in track is identical, contrast by the 1st the first orbit segment and the 1st the second orbit segment, the 2nd the first orbit segment and the 2nd the second orbit segment contrast ... N number of first orbit segment and N number of second orbit segment contrast.Contrast in the N number of similarity drawn, there is M similarity more than the 4th threshold value, then M/N is the first movement locus and the similarity verifying movement locus, namely the quantity of orbit segment that similarity meets the demands accounts for the ratio of the quantity of total orbit segment, it is the similarity of two movement locus, wherein, the quantity of N is larger, and result is more accurate.
Because the orbit segment carrying out contrasting is positioned at the turning point of movement locus, therefore, the method obtaining the first orbit segment is, described first movement locus is divided into multiple orbit segment; According to the radian of each orbit segment divided, from multiple orbit segment, determine the first orbit segment.In like manner, the method obtaining the second orbit segment is, described checking movement locus is divided into multiple orbit segment; According to the radian of each orbit segment divided, from multiple orbit segment, determine the second orbit segment.
Specifically, be divided into P orbit segment by the first movement locus, in order to make result more accurate, the quantity of division can be tried one's best many when conditions permit, namely P is larger, and result is more accurate, but amount of calculation is also larger.In P orbit segment, determine turning point N number of orbit segment, the movement locus due to turning point is camber line, therefore, can according to the radian of each orbit segment, namely radian is greater than the orbit segment of certain certain value is the first orbit segment, can obtain N number of first orbit segment thus.In like manner, N number of second orbit segment can be determined.
In order to prevent mobile-terminal simulator from carrying out information stealth to forge mobile terminal, because do not have motion sensor in simulator, therefore, the embodiment of the present invention also comprised before step S101: the gyroscope model obtaining described mobile terminal; According to the gyroscope model of described mobile terminal, generate terminal iidentification; Described terminal iidentification is identified with the checking preset and compares, if unanimously, then perform the step of the first movement locus obtaining mobile terminal.Can find out, if obtain the success of gyroscope model, then illustrate that mobile terminal is not simulator, can subsequent operation be proceeded; Otherwise, think that this mobile terminal is dangerous.Gyrostatic model can be converted to hexadecimal character string, after this character string is made a summary, generate terminal iidentification.
Further, the embodiment of the present invention is while the gyroscope model obtaining mobile terminal, also obtain IMEI (the mobile device international identity code of mobile terminal, InternationalMobileEquipmentIdentity), the information such as model of manufacturer, model, linear acceleration sensors, similar to the processing mode of gyroscope model, above-mentioned information and gyro sensor model are arranged by regulation order, and be converted to hexadecimal character string, generate the ID of this mobile terminal after this character string is made a summary.By the ID of generation compared with the ID prestored, if unanimously, then illustrate that the confidence level of this mobile terminal is comparatively large, can subsequent operation be carried out; Otherwise, think that the fail safe of this mobile terminal is less.
In the embodiment of the present invention, the coefficient in equation, for setting up coordinate system, by the Representation Equation different tracks section, then compares, using the foundation of the result of index contrast as judgement two orbit segment similarity degrees by the method compared by two orbit segments of employing.Be described in detail for smart mobile phone below.
Specifically, acquisition and the contrast of movement locus can be carried out in the following manner:
1, on mobile phone, user is guided to operate.
1.1, point out user by the long limit reversion of mobile phone, make mobile phone perpendicular to ground.
1.2, point out user only to use any position of a finger contact handset touch panel, normally thumb, and record user and point the position of pressing.
1.3, user's handheld mobile phone is pointed out to write " NZ " aloft.
2, the data that in mobile phone motion process, motion sensor is measured are collected.
Motion sensor in smart mobile phone is divided into linear acceleration sensors and gyro sensor, can experience acceleration and convert usable output signal to.
2.1, coordinate system is set up: point centered by the position of pressing on handset touch panel by user, because mobile phone is moving perpendicular in the plane on ground, the direction of ground side-to-side movement is parallel to for X-axis with mobile phone, the direction moved up and down perpendicular to ground is Y-axis, direction perpendicular to mobile phone plane of movement is Z axis, set up coordinate system, as shown in Figure 3.
2.2, Data Collection sampling: with the tracing point on certain frequency determination movement locus for sampled point, and measured the exercise data of each sampled point by motion sensor.In the embodiment of the present invention, linear acceleration sensors is utilized to measure the acceleration of the XY axial plane of each sampled point, gyro sensor measures the acceleration of XZ axial plane and the radian of each sampled point, wherein, because the acceleration of gravity of each region is different, therefore all acceleration do not comprise acceleration of gravity, avoid the error that acceleration of gravity causes.
Specifically, the acceleration along X-axis that linear acceleration sensors is measured is L
x, the acceleration along Y-axis is L
y; The acceleration along X-axis that gyro sensor is measured is A
x, the acceleration along Z axis is A
z, the unit of above-mentioned acceleration is m/s
2.Meanwhile, the sampling time T of each sampled point is obtained.
3, data analysis.
3.1 sampled points choosing turning point: according to the radian of each sampled point that gyro sensor is measured, judge whether this sampled point is positioned at turning point, sampled point radian being greater than threshold value takes out, and carries out computational analysis.
3.2, the line segment equation between neighbouring sample point is set up:
For XY axis coordinate system, project in the plane at XY axle place by movement locus, get two adjacent sampled point a and sampled point b, then the coordinate of sampled point b in XY axis coordinate system is respectively:

Represent the similarity degree of two movement locus with 0 ~ 1,1 represents that two movement locus are identical, and 0 represents that two movement locus are completely different.By numerical value S within the specific limits
pcorresponding orbit segment is defined as effective orbit segment, such as, by the S of numerical value between 95% to 105%
pbe designated as S
effectivelythe ratio of the quantity of effective orbit segment of some turning points and the sum of the orbit segment of this turning point in first movement locus, be the movement locus of this turning point of the first movement locus and the similarity of the movement locus of the corresponding turning point of checking movement locus, that is: similarity=S
effectively÷ S
sum(5).
First movement locus and the similarity of checking movement locus are the mean value of the movement locus similarity of all turning points.
In like manner, movement locus projects in the plane at XZ axle place, and namely in XZ axis coordinate system, the first movement locus also calculates according to such as above-mentioned identical mode with the similarity of checking movement locus.
Only have the first movement locus all to meet the demands in the similarity of two planes with checking movement locus, could judge that the first movement locus meets the demands with the similarity of checking movement locus, namely be verified.Such as, the first movement locus is all greater than 95% with checking movement locus in the similarity of two planes, then judge to be verified.
In like manner, if user creates the checking movement locus preset, then need to hold mobile terminal and write at least twice " NZ ".As regulation need be write three times " NZ ", this movement locus write for three times similarity each other all higher than 90%, then thinks that checking movement locus creates successfully, times to get a movement locus and preserves as default checking movement locus.
In order to more clearly understand the present invention, with instantiation, above-mentioned flow process is described in detail below.Flow process described by this instantiation as shown in Figure 4, can comprise following components: I, preliminary identification; II, judge; III, checking movement locus is created; IV, authentication of users confidence level.
