Description

Block chain-based student integrity management system and method

Technical Field

The invention relates to the field of integrity management systems, in particular to an on-school student integrity management system and method based on a block chain.

Background

Educational institutions of the school type typically provide school students with services other than teaching, such as libraries for borrowing books from school students, check-in devices for check-in of students during class, and the like. As school students utilize these services, their behavior reflects the degree of integrity accordingly (e.g., borrowing books for return in time, attending class on time, etc.). In order to encourage the honesty of students at school, some schools have provided a honesty reward system, for example, recording the honesty and giving corresponding points, giving rewards (e.g., lengthening the loan time of books, increasing the borrowable amount) further according to the points, and the like. Furthermore, some service organizations outside the school also give corresponding rewards, such as diet discount and telephone fee discount, according to the honesty degree of the students.

In the above-mentioned loyalty award system, the points need to be recorded in correspondence with student information (such as student numbers). One method is to record these pieces of information in a card and perform integration addition and subtraction operations by a card reader/writer. In this case, since the card is the only recording medium, the point can be changed at will by operating the card reading/writing device, so that the recording of the point has a large operability, and it is difficult to reflect the integrity of the student truly, and there is a possibility that an illegal act of tampering the point to earn a reward may be propagated. Another method is to store and manage points with an information management device used by a student management department, but when the information management device fails, the points are lost, and in addition, the form of point management only by the student management department lacks authority, disclosure and fairness, so that the point system is difficult to extend to a service institution outside the school and has no practical significance.

Upon receiving a predetermined number of block confirmation information, the service-side block generation section 27 adds a completion time stamp (i.e., a time stamp indicating the operation completion time) to the currently operated block section under the control of the service-side block control section 31, thereby forming an operated block section. In the present embodiment, the predetermined number of the block acknowledgement messages is half of the total number of the communication nodes in the communication network 4, i.e., half of the total number of the information management apparatus 1, the service terminal 2, and the student terminal 3.

The service-side score operation part 28 is used for performing score operation on the integrity score recorded by the score block part in the integrity blocks. That is, the loyalty score is divided up or down depending on whether the current action is to divide up or down. In addition, there may be a case where the score is not added and not subtracted in the current operation, and in this case, the service-side score operating unit 28 also performs the score operation, but actually the integrity score does not change.

The service-side block recording section 29 is used for recording the integrity block, and the specific configuration and recording rule thereof are the same as those of the management-side block recording section 17, and will not be described again.

The service-side block searching unit 30 is configured to search for the honest blocks, and specifically includes: and analyzing the academic number information contained in the block label in each honest block, and searching the corresponding honest block according to the academic number.

The service-side block control section 31 controls operations of the components related to the block in the service terminal 2, and includes: the control behavior determination unit 24 determines the behavior integrity of the student who receives the service item based on the service item; the control service side retrieval obtaining part 26 retrieves the score operation storage part 25 according to the behavior integrity to obtain the corresponding score operation as the current operation; the control service-side block generating section 27 generates a current operation block section containing the current operation; the control service side communication unit 32 broadcasts the current operation block unit through the communication network 4, and allows the communication units of the other service terminals 2, the student terminals 3 and the information management device 1 to confirm the current operation block unit and send back corresponding block confirmation information; when the service-side communication section 32 receives the predetermined number of pieces of block confirmation information, the control service-side block search section 30 searches the service-side block recording section 29 for an authentic block having a block mark containing the school number, based on the school number; the control service side score operating part 28 performs corresponding score operation on the honest scores recorded by the score block parts in the honest blocks according to the current operation; the control service-side block generation section 27 adds a time stamp indicating the operation completion time to the current operation block section to form an operated block section; the control service-side block recording section 29 adds the operated block section to the corresponding honest block and records it; the control service side communication unit 32 broadcasts the added integrity block through the communication network 4.

Fig. 5 is a schematic diagram of the configuration of the student terminal according to the embodiment of the present invention.

As shown in fig. 5, the student terminal 3 includes a student side screen storage section 41, a student side input display section 42, a student side block recording section 43, a student side block analyzing section 44, a student side block generating section 45, a student side block searching section 46, a student side section value operating section 47, a student side block control section 48, a student side communication section 49, and a student side control section 50.

The student side communication unit 49 is used for transmitting information between the student terminal 3 and other communication nodes on the communication network 4 and between the internal components of the student terminal 3, and the student side control unit 50 is used for controlling and coordinating the operations of the components of the student terminal 3.

The student-side screen storage unit 41 stores screens for allowing students using the student terminals 3 to perform human-computer interaction with each other, including a login screen and a point value transfer screen. The login screen has a login name input field, a password input field, and an information viewing section for allowing the student who enters the login name and the password to acquire and view corresponding information (such as a school code, personal information, etc.) via the information management apparatus 1; the point transfer screen has a point display section for displaying the current honesty points of students and a point transfer operation section for allowing the students to select point transfer. The point assignment operation section has a transfer-to-the-law number input field and an assignment point input field.

The student-side input display unit 42 is used to display the point value transfer screen stored in the student-side screen storage unit 41, and thereby allows students at school to perform appropriate human-computer interaction.

The student-side block recording section 43 records the integrity blocks, and the configuration and operation principle thereof are the same as those of the service-side block recording section 29 and the management-side block recording section 17, and will not be described again.

The student-side block analysis section 44 is configured to analyze the contents of the integrity block corresponding to the holding student number of the student terminal 3, including the current integrity score information included in the score block section and the information of each score operation included in each operated block section, so that the student at school can view these information through the score display section.

The student-side block generation section 45 is used to generate a block section and a new honest block. Unlike the service-side block generating section 27, the student-side block generating section 45 performs two operations at a time: generating two corresponding current operation block parts, namely a current operation block part for performing a division reduction operation on a departure party and a current block operation part for performing a division addition operation on a departure party according to the score transfer information input by the students through the score transfer picture; generating operated block parts formed by the confirmed two current operated block parts respectively; and adding corresponding operated block parts to the corresponding integrity blocks of the transferring-in party and the transferring-out party respectively so as to form new integrity blocks of the transferring-in party and the transferring-out party.

The student side block search unit 46 is configured to search for a corresponding honest block according to the student number. That is, the corresponding honest blocks are found according to the school number of the student at school (i.e., the roll-out party) using the student terminal 3, and the corresponding honest blocks are found according to the school number of the roll-in party.

The student side score operating part 47 is configured to perform score operation on the credit score recorded in the credit block part in the credit block according to the score transfer operation selected by the school student, that is, perform a score reduction operation on the score block part in the credit block of the transferring-out party according to the inputted transfer score, and perform a score addition operation on the score block part in the credit block of the transferring-in party according to the transfer score and the inputted school number of the transferring-in party.

The student-side block control section 48 is for controlling the respective functional units of the student-side block generating section 45, the student-side communication section 49, the student-side score operation section 47, and the student-side block recording section 43. The operation of the integrity management system 100 of the present embodiment will be described with reference to the drawings.

When a student enters the school, the school gives a corresponding school number and distributes the student card. Meanwhile, a manager of the student management department needs to create new student information items at the school, that is, personal information of each newly-enrolled student is entered through the student information entry screen, and the card numbers assigned to the newly-enrolled students are sequentially read by the management-side card reading section 14.

After the entry of the information of the newly entered student is completed, the management-side control unit 20 controls the information storage unit 11 to store the input personal information and the read card number in association with the student number. At the same time, the management-side control unit 20 controls the management-side tile generation unit 16 to generate initial tiles, controls the management-side tile recording unit 17 to record the initial tiles, and further controls the management-side communication unit 19 to broadcast the initial tiles through the communication network 4 so that the tile recording units (including the student-side tile recording unit 43 and the service-side tile recording unit 29) of the other terminals record the initial tiles correspondingly.

FIG. 6 is a flow chart illustrating integrity score management during a service process according to an embodiment of the present invention.

As shown in fig. 6, in the integrity management system 100 of this embodiment, when a student holds a corresponding student card to a service institution to receive a service, the integrity score management process includes the following steps:

in step S1-1, the service-side input display unit 22 displays a service screen to allow the service person to select a service item to be performed and to select a card reading operation, and the service person selects the service item and reads the card number of the student card through the service-side card reading unit 23, and then the process proceeds to step S1-2.

In step S1-2, the service-side communication unit 32 transmits the card number and a school number acquisition request to the information management apparatus 1, and the process proceeds to step S1-3.

In step S1-3, the management-side communication unit 19 receives the card number and the school number acquisition request, and then proceeds to step S1-4.

In step S1-4, the management-side search acquisition unit 15 searches the information storage unit 11 based on the received card number to acquire the school number corresponding to the card number, and then proceeds to step S1-5.

In step S1-5, the management-side communicator 19 returns the acquired school number to the service terminal 2, and then proceeds to step S1-6.

In step S1-6, the service-side communicator 32 receives the school number, and then proceeds to step S1-7.

In step S1-7, the service-side tile controller 31 controls the behavior determiner 24 to determine the plausibility of the student at school who received the service item based on the service item and other related information, and then proceeds to step S1-8.

In step S1-8, the service-side block control section 31 controls the service-side search acquisition section 26 to search the point operation storage section 25 according to the behavioral integrity, acquires the corresponding point operation as the current operation, and then proceeds to step S1-9.

In step S1-9, the service-side block control section 31 controls the service-side block generation section 27 to generate a current operation-block section containing the current operation, and then proceeds to step S1-10.

In step S1-10, the service-side block control unit 31 controls the service-side communication unit 32 to broadcast the current operation block through the communication network 4, and allows the communication units of other terminals and devices (including the service-side communication unit 32 of the other service terminal 2, the student-side communication unit 49 of the student terminal 3, and the management-side communication unit 19 of the information management device 1) to confirm the current operation block and return corresponding block confirmation information, and the process proceeds to step S1-11.

In step S1-11, when the service-side block communication unit 32 receives the predetermined number of pieces of tile confirmation information, the service-side block control unit 31 controls the service-side block search unit 30 to search for an authentic block having a block mark including the school number in the service-side block recording unit 29 based on the school number, and then proceeds to step S1-12.

In step S1-12, the service-side block control unit 31 controls the service-side score operation unit 28 to perform a score operation corresponding to the integrity score recorded in the score block unit of the found integrity block according to the current operation, and then proceeds to step S1-13.

In step S1-13, the service-side block control section 31 controls the service-side block generation section 27 to attach a time stamp indicating the operation completion time to the current operation block section to form an operated block section, and then proceeds to step S1-14.

In step S1-14, the service-side block control section 31 controls the service-side block recording section 29 to add and record the operated block section to the corresponding loyalty block, and then proceeds to step S1-15.

In step S1-15, the service-side block control unit 31 controls the service-side communication unit 32 to broadcast the integrity block formed by the addition via the communication network 4 so that the block recording unit of the other terminal and device (including the service-side block recording unit 29 of the other service terminal 2, the student-side block recording unit 43 of the student terminal 3, and the management-side block recording unit 17 of the information management device 1) records the integrity block, and then enters the end state.

Through the process, the integrity scores of students at school are correspondingly changed. After students perform more integrity behaviors, the integrity scores of the students can be accumulated to a larger numerical value, and each service mechanism can set different service preferential rules aiming at the integrity scores according to actual conditions; accordingly, the service terminal 2 may be provided with a service-side block analysis section, so that when the service person only needs to know the integrity score and does not need to change the integrity score, the service-side block analysis section may analyze the integrity score after the service-side block search section 30 searches for the corresponding integrity block, so that the service person may set the current service benefit according to the integrity score, or may automatically set the service terminal 2 (for example, the service terminal 2 may be provided with a benefit determination section that automatically determines the type of the benefit that should be given according to the integrity score). In addition, the service-side block analysis part can also obtain the current honesty scores (obtained by analyzing the score block part) or the historical honesty scores (obtained by sequentially analyzing each operated block part) according to the actual situation; since the integrity score may be reduced by consumption (e.g., when the service has released a service such as integrity score deduction) or by transfer (e.g., when a school student transfers a portion of the current integrity score to another student), the historical integrity score is more reflective of the school student's past integrity and the current integrity score is more suitable for use in a service that has performed score deduction. The service organization can set the service side block analysis part to analyze the current honesty value or the historical honesty value according to different preferential rules.

As described above, in this embodiment, the school may allow students at the school to transfer a portion of the current integrity score to other students, so that the current integrity score is more fluid and practical.

Fig. 7 is a point transfer flow chart of the embodiment of the present invention.

As shown in fig. 7, the process of assigning a point value to students at school includes the following steps:

in step S2-1, the student side input display unit 42 displays a login screen to allow the student to input a login name and a password, and proceeds to step S2-2 after the input is completed.

In step S2-2, the student side communication unit 49 transmits the entered login name and password to the information management apparatus 1, and the process proceeds to step S2-3.

In step S2-3, the management-side communication unit 19 receives the login name and the password transmitted, and then proceeds to step S2-4.

In step S2-4, the management-side search judging unit 18 searches the information storage unit 11 for the corresponding password based on the received login name, judges whether the searched password matches the received password, returns a password-free message to the student terminal 3 when judged to match and proceeds to step S2-5, and returns a password-error message to the student terminal 3 when judged to not match and proceeds to the end state.

In step S2-5, after the student side communication unit 49 receives the password-error-free information, the student side block control unit 48 controls the student side block analysis unit 44 to analyze the contents of the integrity block corresponding to the student number, and controls the student side input display unit 42 to display the point assignment screen, so that the student at school can view the current integrity point and input the transferee student number and the transference point, and the process proceeds to step S2-6 after the input is completed.

In step S2-6, the student-side block control section 48 controls the student-side block generation section 45 to use the current student number of the user of the student terminal 3 as the number of the transfer-out party, generates the current operation block section for performing the operation of subtracting the transfer-out party and the current operation block section for performing the operation of adding the transfer-in party based on the number of the transfer-out party, the input number of the transfer-in party, and the transfer score, and then proceeds to step S2-7.

In step S2-7, the student side block controller 48 controls the student side communicator 49 to broadcast the two currently operated blocks generated in step S2-6 via the communication network 4, and allows the other terminal and the other communication unit (including the service side communicator 32 of the service terminal 2, the student side communicator 49 of the other student terminal 3, and the management side communicator 19 of the information management device 1) to check the two currently operated blocks and return corresponding block check information, and the process then proceeds to step S2-8.

In step S2-8, when the student side communication unit 49 receives the predetermined number of pieces of block confirmation information, the student side block control unit 48 controls the student side block search unit 46 to search for the corresponding honest blocks based on the study numbers of the roll-in party and the roll-in party, respectively, and then proceeds to step S2-9.

In step S2-9, the student side block control unit 48 controls the student side score operation unit 47 to perform corresponding score operations on the integrity scores recorded in the score block units in the found integrity blocks according to the current operation, and then the process proceeds to step S2-10.

In step S2-10, the student side block control section 48 controls the student side block generation section 45 to attach time stamps indicating the operation completion times to the two current operation block sections, respectively, to form operated block sections, and then proceeds to step S2-11.

In step S2-11, the student side block control section 48 controls the student side block recording section 43 to add and record the operated block portions to the corresponding honest blocks, respectively, and then proceeds to step S2-12.

In step S2-12, the student-side block control section 48 controls the student-side communication section 49 to broadcast the integrity block formed by the addition through the communication network 4 so that the block recording section of the other terminal and device (including the service-side block recording section 29 of the service terminal 2, the student-side block recording section 43 of the other student terminal 3, and the management-side block recording section 17 of the information management device 1) records the integrity block, and then enters the end state.

Examples effects and effects

According to the integrity management system provided by the embodiment, the behavior determination unit can determine the behavior integrity of the student at school, and the service-side search acquisition unit can acquire the corresponding score operation according to the behavior integrity search, so that the student at school can acquire different score operations (i.e., score increase or score decrease) according to different states of the student when receiving the service item, and the operation of adding or subtracting the integrity score can better reflect the behavior integrity of the student at school. The service-side block generating part can generate a current operation block part containing current operation, and the service-side communication part broadcasts the current operation block part and receives a predetermined number of block confirmation information, and then the service-side score operation part performs corresponding score operation, so that each score operation is performed after each communication node in the communication network confirms, thereby avoiding score operation performed by the service terminal under an offline condition, avoiding the score from being tampered privately, and improving the reliability of the system of the embodiment. Furthermore, the current operation block unit is formed into an operated block by the service-side block generating unit after being confirmed and operated, and is broadcast by the service-side communication unit, receives the confirmation information of the predetermined number of blocks, and then is added to the corresponding integrity block.

In addition, the integrity block of the embodiment has a block mark corresponding to the school number and a score block part which is independent from each operated block part, so that the search of each integrity block is more convenient, the score block can be distinguished from each score operation, the score operation which is performed when the current integrity score information is obtained is not required to be traced, and the obtaining process of the current integrity score information is simplified.

In the embodiment, the student terminal is also provided with a student side block recording part, so that each integrity block is recorded in the student terminal, the number of communication nodes in a communication network can be expanded to increase the reliability of the system, and students can conveniently check and transfer scores through the student terminal.

The student terminal is provided with the student side block generating part and the student side score operating part, so that assignment operation can be carried out according to the transfer-in student number and the assignment score input by the students at school, and the integrity score has liquidity and practical significance. Meanwhile, the transfer operation can be only carried out after login, and the current user of the student terminal is directly used as a transfer party, so that the transfer operation is carried out by the user, the operator cannot transfer other people with integrity scores, and the occurrence of malicious transfer behaviors can be avoided. Meanwhile, the working principle of the components associated with the current operation block part, the operated block part and the point operation, such as the student side block generation part and the student side point operation part, is similar to that of the service terminal, so that each transfer operation is performed after being confirmed by each terminal and device, and each operation leaves a record in the block recording part of each terminal and device, and therefore, the reliability of the system of the embodiment can be further improved.

The above embodiments are only used to illustrate specific embodiments of the present invention, and the block chain based student integrity management system of the present invention is not limited to the form described in the above embodiments.

For example, in the integrity management system of the above embodiment, students at a school can transfer integrity points through student terminals. However, in other embodiments, in order to make the integrity score reflect the integrity situation more strictly, the credit score transfer behavior may not be allowed, that is, the relevant component for score transfer is not set in the student terminal, so that the student terminal can only perform the action of information and score viewing.

In the above embodiment, the initial block and each block portion are generated in a form of data packing according to a general data packing rule, and this form makes transmission and reception of data simpler, and makes system operation more efficient, but is not favorable for information security, and thus is suitable for a more closed campus network. However, in the present invention, the initial block and each block part may be generated in an asymmetric encryption manner, that is, the initial block or the block part is encrypted by using a public key, and the public key of the information management apparatus that generates the initial block or the public key of the terminal that generates the block part is broadcasted at the same time, so that each other communication node can decrypt the information by using the previously stored private keys corresponding to each different public key, thereby obtaining the contained information. The asymmetric encryption is complex in form, corresponding public keys and private keys need to be distributed when a network is built or a communication node is newly added, but information transmission is safer, so that the asymmetric encryption is more suitable for an open network.

In the above embodiment, the information storage unit further stores a login name and a password corresponding to the school number, so that the school student can use a login method when using the student terminal. However, in the present invention, the student terminal may be provided with the student-side card reading unit instead of the login name and the password, and the student approaches the card reading unit to read the card number when the student uses the student terminal to perform the checking or transferring operation, and the student-side communication unit may transmit the card number to the information management device, and may perform the same operation as that performed after the student logs in by the login name password in the embodiment after receiving the corresponding student number.

While the present invention has been described in detail with reference to the preferred embodiments, it should be understood that the above description should not be taken as limiting the invention. Various modifications and alterations to this invention will become apparent to those skilled in the art upon reading the foregoing description.
