Embodiment
Below summary of the invention of the present invention and claim are described in further detail.
One, mobile terminal, attendance record terminal and work attendance server and the network architecture thereof
The relation that system of the present invention comprises mobile terminal, attendance record terminal and work attendance server as shown in Figure 1.Work attendance server 10 is connected by network 20 with mobile terminal 40; Mobile terminal 40 obtains Classroom Information by taking the two-dimension code image of being shown by attendance record terminal 30.
Mobile terminal is generally mobile phone or palm PC, is in particular smart mobile phone.General mobile phone, palm PC are all built-in with the display device such as network connection device (Wifi) and image-input device (camera) and display screen.The network connection device of mobile terminal is for establishing a communications link with work attendance server.Under the solution of the present invention, mobile terminal is generally privately owned by student.
Attendance record terminal can be mobile phone or palm PC, the mobile phone of holding such as the teacher that attends class.Attendance record terminal can be also fixing terminal device, such as the computer being arranged in information classroom.
Work attendance server is added to be provided with for preserving classroom register record and occurrences in human life Database Systems.
Two, Classroom Information
In the present invention, Classroom Information is to be generated and be sent to work attendance server by mobile terminal by attendance record terminal.Class offerings refers to the content being comprised of classroom ID, the content of attending class, class period, the classroom of attending class, the teacher that attends class etc.
Classroom Information can be class offerings.
Classroom Information can be also the informative abstract of class offerings.The informative abstract of class offerings, is indication Classroom Information summary of the present invention, refers to the Hash Value that class offerings obtains through hash function computing.Work attendance server finally receives after Classroom Information summary, finds out Classroom Information summary and the Classroom Information the receiving identical class offerings of making a summary from school timetable database.Here, school timetable database is for preserving the database of Classroom Information list.It will be appreciated by those skilled in the art that as accelerating the seek rate of " find out Classroom Information summary and the Classroom Information receiving make a summary identical class offerings " from school timetable database, can set up in advance the mapping table that class offerings and Classroom Information are made a summary.
In actual application, Classroom Information can also comprise the teacher's that attends class digital signature.Teacher's the digital signature of attending class is also the teacher's digital signature in claim, is that the private key by the teacher that attends class obtains class offerings combine digital signature algorithm.In the present invention, Classroom Information preferentially comprises Classroom Information summary and the teacher's that attends class digital signature.In Classroom Information, add the teacher's that attends class digital signature can prevent that student from forging Classroom Information.
Here, hash function is one-way hash function and claims again One-way Hash function.Adoptable algorithm is a lot, such as: MD5, SHA, CRC etc.In the present invention, the preferential < < SM3 cryptographic Hash algorithm > > adopting by national commercial cipher management office standard of hash function; Teacher's Digital Signature Algorithm preferentially adopts the Digital Signature Algorithm in the < < SM2 elliptic curve cryptography > > of national commercial cipher management office standard.
Three, student's characteristic information
In the present invention, student's characteristic information be the mobile terminal held by student be issued to work attendance server for identifying student's information.Work attendance server generates the final classroom record of registering according to student's characteristic information and aforesaid Classroom Information.
Student's characteristic information can be student information, such as student's name or student number etc.
Student's characteristic information also can comprise the feature identification code of mobile terminal.The feature identification code of mobile terminal is referred to as terminal feature code, for identifying the information of mobile terminal, such as phone number, MEID or IMSI etc.
Student's characteristic information can be only also the feature identification code of mobile terminal.In this case, need in work attendance server, set the corresponding table of the feature identification code of a mobile terminal and student's relation.By inquiring about the corresponding table of this relation, work attendance server can be found out student according to the feature identification code of the mobile terminal receiving, the record thereby register in generation classroom.
Student's characteristic information can be also student information, or the feature identification code of mobile terminal or both are in conjunction with the hashed value obtaining by one-way hash function computing (being also the Hash Value that the computing of hash function hash obtains).In this case, need in work attendance server, be provided with student's characteristic information and student's the corresponding table of relation.By inquiring about the corresponding table of this relation, work attendance server can be found out its corresponding student according to the student's characteristic information receiving, the record thereby register in generation classroom.
Middle school student's characteristic information of the present invention is preferably the Hash Value that the feature identification code by student information and mobile terminal mutually combines and obtains by after the computing of hash function hash, is provided with student's characteristic information and student's the corresponding table of relation in work attendance server.
Four, attendance record terminal
In the present invention, attendance record terminal is for generating the two-dimension code image of Classroom Information and showing two-dimension code image.
According to Classroom Information, generating two-dimension code image is prior art, is not repeated.
Attendance record terminal shows that two-dimension code image can have following approach:
1, attendance record terminal is shown two-dimension code image by the display screen of attendance record terminal.In suc scheme, attendance record terminal need to provide a display screen.
2, attendance record terminal prints two-dimension code image by printer.In suc scheme, attendance record terminal need to connect printer.
3,, in information classroom, attendance record terminal is sent to two-dimension code image on each computer, and by each computer display.
Five, mobile terminal
In the present invention, by the application program of installing on mobile terminal, realize the classroom of the present invention function of registering.The function that this application program mainly completes is:
