Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The method as shown in Figure 1, a kind of classroom of multi-modal authentication proposed by the present invention is registered, overall flow include:
Step 1, design classroom instruction are registered screen locking process；
Step 2 is established and is based on GPS, two dimensional code, sound wave and the multi-modal Authentication mechanism of recognition of face；
Step 3, design ensure the mobile phone screen locking mechanism of classroom instruction.
The present invention proposes two kinds of embodiments, if then used in the classroom for having the end PC and projector " GPS --- two
Dimension code --- recognition of face --- completion of registering locks screen automatically " technology of registering；If in outdoor or without the class at the end PC
On, then use the technology of registering of " completion of registering locks screen automatically GPS --- sound wave identification --- ".
Embodiment one:
1) teacher starts instruction of registering by smart phone publication, and sets origin reference location.
The class period is closed on, teacher's selection is registered, determine oneself position, as shown in Fig. 2, method particularly includes: teacher passes through
Smart phone obtains current course, judges whether current course is empty, is to register unsuccessfully, and otherwise teacher clicks publication and registers
Instruction obtains GPS positioning information dt and is uploaded to server end, and server end sets origin reference location.
2) each student replys instruction of registering by smart phone, judges student's GPS positioning data and origin reference location data
Whether within error range, it is to go to step 3), otherwise registers unsuccessfully.
As shown in figure 3, student obtains current course by smart phone, judge whether current course is empty, is to register
Failure, otherwise judges whether current course obtains instruction of registering, otherwise registers unsuccessfully, be, obtains GPS positioning information ds upload
To server end.
Server end obtains the point dt and ds of teacher end and student side in GPS positioning, develops for present design
Application software in, by means of the API of Baidu map, by accessing Baidu map API, the flat of GPS positioning may be implemented
Equal error k≤40 meter, and actually in class tested by application software in teacher, correlation data judges student's GPS positioning
Whether data and origin reference location data are within error range.It has been determined teacher end anchor point dt's and student side anchor point ds
Range error d [ds~dt] is that less than 100 meters authentication authorization and accountings of radius r are that GPS registers success by both centers of circle distance of dt.
Student's smart phone will open GPS background service on backstage and monitor student current location in real time after registering successfully, often
A data are sent to server every a period of time such as 30s, judge whether it leaves classroom range during class hours.
3) two-dimensional barcode information information is issued, student scans the two-dimensional code information by smart phone and registers, server end
Verifying information of acoustic wave simultaneously records information of registering.The end PC announce two dimensional code, teacher sweep mobile terminal two dimensional code be added Classroom Information and
Artificial number, student side sweeps two dimensional code, and decoded information completion consistent with Classroom Information and teacher's work number is registered.
Two dimensional code need to be by the PC end projection to classroom large screen of classroom, it is contemplated that classroom computer is not necessarily mutual with network
Connection, it is meant that it is consistent with network time not can guarantee its system time.Therefore, it is necessary to record the time of computer on two dimensional code,
And primary (tf is the two dimensional code update cycle) is synchronized every tf.When verifying, the publication of teacher elder generation barcode scanning is registered, this in the process can
Time and the generation of classroom end PC at this time two that rear server-side receives teacher's two-dimensional code data are scanned the two-dimensional code to obtain teacher side
The time difference for tieing up the code time is denoted as poor Δ t1 at the first time, obtains student side and scans the two-dimensional code rear server-side reception student side two
The time for tieing up code data generates the time difference of two dimensional code time with classroom end PC at this time, is denoted as the second time difference Δ t2, establishes mould
Type:
Δ t1=tt1-tt0
Δ t2=ts1-ts0
Δt2-Δt1<tf+c
Wherein, tt1 indicate teacher's two-dimensional code data in time, tt0 be server-side receive teacher's two-dimensional code data when
Between, ts1 is the time in student's two-dimensional code data, and ts0 is the time that server-side receives student's end data, and tf is two dimensional code
Update cycle, c are the time-consuming error of two dimensional code transmission twice.By test, c=10000 is taken, unit is millisecond.That is (student
Classroom machine time when classroom machine time-teacher's barcode scanning when barcode scanning)-(server-side receives two-dimensional code data after student's barcode scanning
When m- teacher's barcode scanning after server-side receive time of two-dimensional code data).It is equally student's barcode scanning and religion in first bracket
The interval time that two behaviors of teacher's barcode scanning occur, worst error are the update cycle of two dimensional code.Second bracket is swept for student
The interval time that code occurs with two behaviors of teacher's barcode scanning, error are the error of network transmission time-consuming twice.So two
Bracket makees difference certainly less than tf+c.
For decoding scheme in decoding, teacher calls smart phone rear camera to obtain image in 2 D code, flat using system
Platform official two-dimensional code decoder can be obtained the two-dimensional code data of setting.After getting two-dimensional code data, set when according to coding
Separator "-" obtain work number substring number2, teacher's work number number of itself and current class hour are compared, if number=
Number2 then verifies the errorless upload of work number.Teacher's barcode scanning is registered the class hour after uploading becomes function publication, and student can start to sweep
Code is registered.
Two-dimentional code scheme will make two dimensional code have actual verifying performance, need to guarantee two dimensional code coded data
Uniqueness and timeliness.In uniqueness, coded number is added in unique identification that each teacher is had --- work number number
According to.In timeliness, the millisecond time of current time is indicated coded data is added, while teacher being allowed to set this time
The update cycle tf of string.The update cycle tf of teacher's setting can also be added in coded data, in addition a network delay
Error c is exactly the error for verifying two dimensional code timeliness.
4) student carries out recognition of face by smart phone camera, and server end is verified recognition result and recorded and registers
Information.
As shown in figure 4, student opens front camera and carries out human face scanning after the completion of two dimensional code is registered, verify whether
For my login, system prestores everyone facial head portrait, when carrying out recognition of face, system according to the eyes of each human face,
These three main features of nose, mouth and the overall profile of each face are analysed and compared, it is determined that one identification
Similarity similarity, if meet similarity >=85% be successful match, be proved to be successful open system lock
Screen, authentication failed then need to register again.
5) Intelligence of Students mobile phone is by screen locking, automatic unlocking after End-of-Course.
After screen locking, the display screen of mobile phone will be disabled, and all touch key-press can not use, and remember since screen locking
The active state of mobile phone is recorded, if student, which will be recorded data using mobile phone by danger button pressure, is uploaded to server.
Time started of attending class is more than three minutes or more, and student registers success, then record is late and is uploaded to server.On
During class, student side keeps the primary real-time positioning of verifying in 30 seconds to press if will be denoted as and leave early not in range for continuous five minutes
Teacher's setting, which is taken off, usually to divide；It registers after screen locking, in automatic unlocking after class, is incited somebody to action if class period student unlocks by force manually
It is recorded undisciplined, is taken off and usually divided by teacher's setting, teacher side can check and eliminate this undisciplined information；Student terminates at school
It does not register to be denoted as yet afterwards and cut classes, take off by teacher's setting and usually divide.
Embodiment two:
The difference of embodiment two and embodiment one is only that step 3), other steps are consistent with embodiment, repeat no more.
3) information of acoustic wave is issued, student identifies that information of acoustic wave is registered by smart phone, and server end verifies sound wave
Information simultaneously records information of registering.
31) frequency of sound wave function is set, every sonic data sound duration is 100ms, after starting sounding, generator
The sound wave f 1 for having fixed frequency after loop play is encoded defaults the time character in every 10s update first encoding data
String will be automatically stopped for three minutes after opening sounding；
32) student identifies that information of acoustic wave is registered by smart phone, and student side receives identification sound wave and obtains frequency
F2, f2=f1 are to identify successfully, then verify whenever recognizing primary complete valid data, are then stopped immediately by verification
Identification, does standardization processing to inspection data, retransmits to server-side and carries out timeliness verifying, the verifying of server end timeliness
By success of then registering, this step is otherwise repeated.
Sound wave identifies that Technology application of registering combines the characteristics of current cell phone can receive and dispatch sound wave, and encoding scheme exists
It is similar with two dimensional code coding when acoustic coded, it is also desirable to which that coded data has uniqueness and timeliness, since sound wave is vulnerable to dry
A period is disturbed and spans, therefore compared with two dimensional code coded data, acoustic coded data demand data are simplified as far as possible to improve
Communication speed, setting check bit are to improve the precision of communication, setting starts identifier and guarantees to confirm the validity data in communication
Beginning and end.Coded data is indicated with following model: it is current coded data: to start symbol first+ work number substring number+
Time millisecond indicates rear six timeNumber+check bit checkNumber of string；Valid data: work number substring number+
Six timeNumber after timestamp, when work number is greater than four: four after work number substring number=work number, otherwise: work
Work song string number=work number；Check bit checkNumber=(valid data length length+ valid data each
EachLength), after coded data determines, sound wave function, sound wave function are passed into the generator of system platform official offer
For a SIN function y (z, t)=A (z, t) sin (kz-wt+ φ), z is the time in formula, and k is wave number, and t is the time, then A
(z, t) indicates amplitude, and φ is phase.Sometime, the waveform of sound wave is sinusoidal waveform, and equation is expressed as y=Asin
(wt+ φ), A is amplitude in formula, and w is angular speed, and φ is initial phase.The frequency of sound wave function is set according to following code book: being compiled
Code book:--2000HZ ", -0-2300HZ ", -1-2600HZ " ... -9-5000HZ " wherein-- " be start to identify
Accord with first.According to setting, bits per inch is 100ms according to sound duration.After starting sounding, after generator encodes loop play
Sound wave defaults the time character string in every 10s update first encoding data.It will be automatically stopped within three minutes after opening sounding, teacher
It can be shut down manually according to situation of registering.
It is measured by experiment, in the phonation time of 100ms, sounding number average out to that smart phone decoder recognizes
It 22 and keeps restraining.For this purpose, recognition result is recorded as original character string, continuous character recognition processing is done to it: continuous identification
It regards as 0-33 times as the sounding of a 100ms, regards as 2 sounding ... 99-110 and regard as 5 sounding 110 for 33-55 times
The above are 6 sounding, are then split according to beginning identifier to original character string, are once completely had whenever recognizing
Effect data then verify immediately.By verification then stop identifying, standardization processing is done to inspection data, retransmit to server-side into
The verifying of row timeliness.Timeliness is verified success of registering, and otherwise needs to re-recognize.
