Description
Technical Field
The invention discloses a block chain-based academic calendar and academic degree authentication method, and belongs to the technical field of academic calendar and academic degree authentication methods.
Background
In China, a academic certificate and a degree certificate are important certificates for proving the educational experience of an educated person, and most of the time, companies or deeply-built schools require the educational experience certificate to be provided when the applicant applies for the certificate, no matter whether the education experience is for work or the education is selected to be continuously deeply built. Therefore, various certificate counterfeiting behaviors appear in society, and the authentication work of academic calendars and academic certificates is more important due to the appearance of the behaviors. The certification of academic calendars and degree certificates is necessary in many cases, such as talent recruitment by units, college and university college researchers in China, and application of students abroad.
At present, the authentication of domestic academic calendars and academic certificates can be specifically divided into two types according to the places to be educated: internal academic records and academic degree certification and external academic records and academic degree certification.
For domestic academic records and academic degree certification, the application can be submitted on the internet, or the academic records and academic degree certification can be carried out at a designated place institution. However, in any application method, the authentication flow after application is the same, and after the authentication is finished, the applicant receives a written authentication report from the authentication institution, and at present, in addition to the written authentication report, the education department provides a diploma electronic registration inquiry service, but in many cases, the service can be used only in some informal occasions, and many overseas colleges and staff units still require the applicant or the applicant to provide the written authentication report.
For the foreign academic calendar and academic degree certification, the certification application is carried out at the academic department study service center, and the certification scope comprises the academic degree certificate obtained at foreign or foreign university or higher education institution, and the foreign academic calendar and academic degree certificate of the cooperative institution or project approved by the education administration department of the national institute. The applicant needs to submit the proof material such as the academic calendar, the academic certificate passport, etc., and the foreign language information needing to be translated in the application material also needs to be translated by a professional foreign translation agency.
The authentication process of the academic calendar and the academic certificate and the file management work of the colleges and universities are complementary. Colleges and universities first collect the files of students, then archive and group the files, classify the files, and finally provide a database which can be consulted. After the applicant provides the certification application to the academic calendar and academic institution, the certification institution sends the certification application to the school file management department, and then the school file management department receives the application, consults and verifies the file management database of the school, returns a certification result to the certification institution, and finally, the certification institution provides a written certification report to the applicant.
At present, the authentication process for academic calendars and academic certificates in or out of the country has certain inconvenience, as follows: 1. time, manpower, material resources cost: an accurate academic calendar and academic certification written report requires participation of multiple parties including, but not limited to, applicants, certification authorities, schools, and the need for the cooperation of many people. Especially, foreign academic calendars and academic degree certification also require work such as translation and material transportation. 2. Cost of school database: as described above, schools need to establish a huge database for storing the scholars and academic degree archive information of students, and the creation and operation and maintenance of the database need a cost of 3. the stability of data storage is not sufficient: a common problem with centralized databases is data storage, which is difficult to recover once the server storing the database is down.
In summary, at the present stage, the domestic academic calendar and academic degree authentication mode needs to simplify the process of the academic calendar and the academic degree authentication under the condition of ensuring the accuracy and safety of the authentication process, and the cost of the academic calendar and the academic degree authentication is reduced.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to solve the technical problems that: an improvement of a block chain-based academic calendar and academic degree authentication method is provided. The block chain technology is used for realizing the authentication of the academic calendar and the academic certificate by solving the existing problems of the academic calendar and the academic certificate.
In order to solve the technical problems, the invention adopts the technical scheme that: a block chain-based academic calendar and academic degree authentication method comprises the following steps:
the method comprises the following steps: colleges and universities register an Ether house account before issuing the electronic version files of the academic calendar and the academic degree certificates, then apply for authorization in an academic calendar/academic degree authentication system, and can issue the academic calendar and the academic degree certificates after obtaining the authorization;
step two: colleges and universities upload files of electronic version academic calendars and academic certificates to an academic calendar/academic certification system, then grant the electronic version academic calendars and academic certificates to students, and meanwhile disclose college Ether house account numbers;
step three: the academic calendar/academic degree authentication system calculates the hash value of the electronic version academic calendar and the academic degree certificate file at the interactive end, and records the hash value and the ether workshop account number of colleges and universities on the ether workshop;
step four: the student sends the electronic version academic calendar, the academic degree certificate and the address of the Ethenhouse account number of the colleges and universities to the authenticator;
step five: the authenticator uploads the received academic calendar, academic certificate and Ethenhouse account number of colleges and universities to an academic calendar/academic certification system;
step six: and the academic calendar/academic degree authentication system calculates the hashed values of the electronic version academic calendar and the academic degree certificate uploaded in the fifth step at the interactive end, and then refers to the record stored in the ether workshop to verify the authenticity of the electronic version academic calendar and the academic degree certificate.
The academic/academic certification system comprises an interaction end and a block link end, wherein all business logic of the block link end is realized by intelligent contracts on an Ethernet workshop;
the interactive end specifically adopts a webpage or a mobile end, the webpage is mainly realized by HTML, CSS and Web3.js, and the function of recording data on the block chain is realized directly by interaction of Web3.js and an intelligent contract on an Ethern;
the method is mainly realized by mobile application of an android terminal and a Java library of Web3j in a mobile terminal mode, and the file records are stored on the Ethernet workshop by calling an intelligent contract on the Ethernet workshop through Web3j in the android application.
The hash value in the third step and the sixth step is specifically calculated by using the MD5, SHA1, SHA256 or SHA512 hash algorithm, so as to obtain a hash value capable of determining that the hash value uniquely represents the certificate file, and the calculated hash value is different from the previous hash value once the file is tampered.
The specific process of the step one is as follows:
when the front end of the academic calendar/academic degree authentication system is presented in a webpage form, colleges and universities download a browser plug-in Metamask, the front end acquires the current Ethernet account information of the Metamask through Web3.js, then the colleges and universities submit authorization applications on the academic calendar/academic degree authentication system, and after receiving the applications, a system manager stores the account number of the colleges and universities into a list in an intelligent contract, wherein the list is specially used for storing the account number information of the colleges and universities.
The sixth specific process of the step is as follows:
the first front end uses Web3.js or the mobile end uses Web3j to obtain all event lists which are triggered by the intelligent contracts deployed on the Etherns;
then, the academic calendar/academic degree authentication system calculates the hash value of the electronic edition academic calendar and the academic degree certificate file uploaded in the step five at the front end;
then, whether an event exists in the list is consulted, the record of the event contains the calculated hash value, and the corresponding college ether house account number is also the same as the college ether house account number uploaded in the step five;
if the same event record exists, the academic calendar and the academic certificate uploaded in the step five are proved to be authentic and credible, and if the same event record does not exist, the academic calendar and the academic certificate are proved to be unreliable.
Compared with the prior art, the invention has the beneficial effects that:
1. the data is stored more safely and stably, and the database cost is reduced:
in the current-stage certificate authentication process of the academic calendar and the academic degree, the academic calendar and the academic degree files of students are stored by a centralized database maintained by colleges and universities, the centralized database is easily affected by single-point failures, once a database server goes down, the recovery of data is difficult, if the storage of the data is safer by adding redundancy, the cost for maintaining the database is increased. The technical scheme of the invention adopts the block chain to store the record of the academic calendar and the academic degree. Each node in the blockchain has a complete archive record, and most nodes in the blockchain network can still maintain the archive records normally even if the records of one or a few nodes are tampered or the nodes are down.
In addition, colleges and universities use centralized databases to store student record files, the creation and operation and maintenance of the databases require labor and server costs, ether workshops are selected as data storage platforms, and the colleges and universities can record data in the ether workshops only by paying a small amount of commission fees when uploading certificate files.
2. Certificate authentication no longer requires a third party certification authority, and the authentication process is simplified:
the certification applicant applies to a third-party certification authority, the third-party certification authority finds an application for the colleges and universities to submit a file for reference, the colleges and universities refer to the file and then feed results back to the third-party certification authority, the certification authority issues a certification report to the applicant, and finally the applicant submits the report to a relevant unit requiring academic degree certification.
In the scheme of the invention, a platform is built by using a block chain, and the requirements of students, colleges and universities and related units requiring academic calendars and academic degree certification can be realized by directly accessing the platform. Colleges and universities directly store the academic calendar and academic degree archive information in the system (namely on the Etheng adopted by the system), students and relevant units requiring academic calendar and academic degree authentication can directly upload certificate files in the system, and the system can verify the authenticity of uploaded academic calendars and academic degree certificates by looking up the archive information stored in the system.
3. The authentication mode and the mode of sharing the authentication result are simple and rapid:
as described in the above description of the technical contents, the electronic version academic calendar and academic degree certificate file can be directly used as a file for displaying the educational experience, and can also be used as a tool for authenticating the academic calendar and academic degree certificate file in the invention, so that students can refer to and verify the authenticity of the academic calendar and academic degree certificate only by sharing the certificate file when applying for employment or applying for deep construction. After the files are uploaded to the system of the invention from colleges and universities, students and other units (such as recruiters and college research institutes) requiring academic degree certification can directly upload academic calendars and academic degree certificate files, and after the files are uploaded, the uploaders can immediately obtain the certification results.
Drawings
The invention is further described below with reference to the accompanying drawings:
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the principle of the block chain-based academic calendar and academic degree authentication method provided by the present invention is to use a block chain technology to authenticate the academic calendar and academic degree certificate by solving the existing problem of the academic calendar and academic degree certificate.
The block chain is simply a decentralized distributed database ledger, no central node exists, each node in the block chain network can copy and synchronize the whole ledger, the ledger is of a chain structure and is composed of a plurality of blocks, ledger record data in the block chain network are stored in the blocks in the form of transaction information, the blocks are arranged according to the issuing time sequence and are connected in series through an encryption algorithm, and each block stores a ciphertext of the last issued block, so that the chain structure is formed. The structure and design of the blockchain enable the data storage of the blockchain to be distributed, stable and safe, and as the network nodes on each blockchain can copy and store a copy of the database, the blockchain cannot be affected by a single point of failure (the single point of failure: any single node is down or off-line, and cannot affect the storage and safety of the data), and even if the data of one or a few nodes is tampered, the safety of the account book can still be guaranteed because most nodes in the network maintain a real and credible account book. In addition, due to the special chain structure of the blockchain (i.e. the block holds the ciphertext of the previous block), it is confirmed that the issued block is difficult to be revoked or tampered, which makes the blockchain have the characteristic of being difficult to be tampered. From the above description, it can be also understood that the security of the blockchain also depends on the number of nodes in the blockchain network to some extent, and the greater the number of nodes, the greater the difficulty of tampering the ledger. Therefore, the system uses one of the blockchain networks with the largest number of nodes in the current network: ether house.
An etherhouse is an open-source, common blockchain platform with intelligent contract functionality, where an intelligent contract is an application or program that a developer deploys to run on a blockchain. Methods can be implemented in the intelligent contract, which mainly implement some operations of the blockchain end, such as recording data onto the blockchain, trading cryptocurrency, and the like, and the method in the intelligent contract can be called by the outside world through some special interfaces to implement the interaction between the front end and the blockchain. In the scheme, Web3.js is used as an interface for interaction between the front end and the intelligent contract.
Js is a library of JavaScript that encapsulates interfaces that can interact with smart contracts, e.g., JavaScript can be used to call methods in blockchains.
In the present invention, the implementation logic of the academic calendar and academic degree certification can be described as the following steps:
0. before describing the specific operation flow, the operation environment and some basic designs of the system will be described.
The user interaction end, namely the front end, of the system is presented in the form of a webpage and is mainly realized by HTML, CSS and Web3. js. All business logic at the end of a block is implemented in the intelligent contracts of the invention deployed on an ethernet bay. The front end directly interacts with an intelligent contract on an Etherhouse through Web3.js to realize the function of recording data on the blockchain.
FIG. 1 is a flow chart of the method of the present invention, illustrating the flow of the academic calendar and academic degree certificate from archival collection, archival storage, to certificate granting and certificate authentication in the system of the present invention. In the figure, a publisher represents a college issuing a academic calendar and a academic certificate, a system manager represents a role of management authorization to determine which account numbers can issue the academic calendar and the academic certificate on the platform of the invention, and a verifier represents a relevant unit (such as a talent unit for recruitment, a college for reading a researcher upon application, and the like) for requiring a student to submit the academic calendar and the academic certificate authentication report.
1. Colleges and universities need to register an Ether account before issuing the electronic version files of the academic calendar and the academic degree certificates, then apply for authorization in the system of the invention, and can issue the academic calendar and the academic degree certificates after obtaining the authorization.
The front end of the invention is presented in a webpage form, and colleges and universities can download a browser plug-in Metamask which is an Ethenhouse encrypted wallet application, so that the invention can be helped to create an Ethenhouse account number and manage the transaction of the invention on the Ethenhouse. The front end of the invention can also obtain the current Ethernet account information (account number) of Metamak through Web3.js, then colleges and universities can submit authorization applications on the system, and after receiving the applications, a system manager can store the account number of the colleges and universities into a list in an intelligent contract, wherein the list is specially used for storing the account number information of the colleges and universities.
2. Colleges and universities upload files of electronic version academic calendars and academic certificates to the system of the invention. And then, the electronic version academic degree certificate is granted to the student, and meanwhile, the Ethenhouse account number of the colleges and universities is disclosed.
When colleges grant the electronic version of the academic calendar and the academic degree certificate of students, the electronic version files of the academic calendar and the academic degree certificate are uploaded to the system, and the Ethengfang account number of the uploaded files is published for subsequent academic calendar and academic degree authentication.
3. The system of the invention calculates the MD5 value of the electronic version academic calendar and academic degree certificate file at the front end, and records the MD5 value and the Ether workshop account number of colleges and universities on the Ether workshop.
The method comprises the steps of calculating an MD5 value by an MD5 algorithm at the front end, calling a method for issuing a scholarly calendar and a scholarly degree certificate in an intelligent contract through Web3.js, triggering an event form by taking the MD5 value and an Etherhouse account number of colleges and universities as parameters, and recording the MD5 value of the scholarly calendar and the scholarly degree certificate and the Etherhouse account number of colleges and universities on the Etherhouses.
4. Students may send an electronic version of the scholarly calendar, a degree certificate, and the Etherhouse account address of colleges and universities to an institution (e.g., a human-using entity, applied student school) that requires them to provide a certification report, which is referred to herein as an authenticator.
The students share the electronic version scholarly calendar, the academic certificate file and the Etherhouse account number of the colleges and universities to the institution requiring the certification report. The subsequent institutions can directly check and verify the authenticity of the certificate through the electronic version academic calendar, the academic certificate and the Etherhouse account number of colleges and universities.
5. The authenticator uploads the received academic calendar, academic certificate and college Ethenhouse account number to the system of the invention.
The authenticator uploads the acquired academic calendar and academic degree certificate files to the system of the invention, and inputs the Ethenhouse account number of the colleges and universities corresponding to the certificate.
6. The system calculates the MD5 values of the electronic version academic calendar and the academic degree certificate uploaded in the step 5 at the front end, and then refers to the record stored in the ether workshop to verify the authenticity of the electronic version academic calendar and the academic degree certificate.
The head-end uses Web3.js to obtain all event lists which are triggered by the intelligent contracts deployed on the Etherns. Then, the system calculates the MD5 value of the electronic version academic calendar and academic degree certificate file uploaded in step 5 at the front end, and then the invention will look up whether there is an event in the list, whose record contains the MD5 value calculated by the invention, and its corresponding college ether house account number is the same as the college ether house account number uploaded in step 5. If there is such event record, then prove that the academic calendar, academic certificate uploaded in step 5 are true and authentic, otherwise prove that the academic calendar, academic certificate are not authentic.
In the scheme of the invention, a webpage form is adopted as a platform for front-end user interaction, and in fact, the method can also be made into android application of a mobile terminal. The method comprises the steps that a JavaScript library of Web3.js is adopted by an original webpage end to realize intelligent contract interaction between a front end and an Ether house, so that the purpose of storing archive records on the Ether house is realized, and if the method is to be made into mobile application of an android end, the method can use the Java library of Web3j to call the intelligent contracts on the Ether house to store the archive records on the Ether house through Web3j in the android application.
MD5 is a commonly used hashing algorithm that computes a certain 128-bit hash value (referred to herein as the MD5 value) each time a piece of data (e.g., a string or file) is entered, and the hash value changes if any change occurs in the entered data. In the scheme of the invention, the MD5 value of the file of the academic calendar and the academic degree certificate is uploaded to the EtherFang as the representation of the certificate file, and in fact, the invention can select other hash algorithms besides the MD5 value to calculate a hash value which can determine the unique representation of the certificate file. And requires that once the file is tampered with, the computed hash value is also different from before. For example, the present invention may also use secure hash algorithms such as SHA1, SHA256, SHA512, etc.
When an event is triggered, the parameters carried by the event are stored in a log of a transaction and then stored in a new block, so that the aim of recording data on the Ethermen is fulfilled. The logs of the trigger events are hooked with the contracts of the trigger events, and the invention can acquire the event list which specifies that the contracts are triggered once by determining the contracts.
The reason why the MD5 value of the electronic version academic calendar and academic degree certificate file is selected to be uploaded instead of the academic calendar and academic degree certificate file is that: one drawback of blockchains itself is the capacity problem. As described above, all nodes in the blockchain copy and synchronize a complete data account book in the network, the account book of the blockchain becomes huge with time, if the invention uploads a large number of certificate files, the size of the account book becomes too large, and the account book information is larger than the hard disk storage capacity of some nodes, at this time, the nodes cannot participate in the maintenance work of the account book.
The technical scheme of the invention has the following characteristics:
1. the invention adopts the form of directly uploading electronic version academic calendar and academic certificate files by colleges and universities to store the academic calendar and academic certificate records of students in the system of the invention. According to the invention, by setting the access authority for the function of issuing the academic calendar and the academic degree certificate file, only the institution authorized by the invention can issue the academic calendar and the academic degree certificate file, and finally the authenticity of the academic calendar and the academic degree certificate record stored in the system can be ensured. The operation avoids the complex flow of uploading files by students and auditing by education institutions, and really ensures the authenticity and reliability of student's academic calendar and academic certificate files uploaded to the system of the invention from the source. The student calendar and the student degree certificate file are directly used as the student calendar and the student degree file stored in the system, after the hash value of the student degree certificate file is uploaded and stored on the block chain, the student calendar and the student degree certificate file can be used as the certificate of authentication, students can share the certificate to the user unit in different texts when applying for employment or deep construction, and the user unit can directly use the student calendar and the student degree certificate file as the certificate of inquiry and authentication.
2. In the technical scheme of the invention, the electronic version academic calendar and academic degree certificate file can be used as a file for directly displaying the educational experience and also as a certificate for authenticating the academic calendar and academic degree certificate file, and students can refer to and verify the authenticity of the academic calendar and the academic degree certificate only by sharing the certificate file when applying for employment or applying for deep construction. The student's academic degree certificate is uploaded directly by the education institution, but not the student uploads the record, and then the record is published on the blockchain after the student finds the education institution to verify. The scheme of the invention ensures that the academic record and the academic certificate record uploaded to the system are real and feasible from the source by setting the access authority for the functions of issuing and learning the academic certificate of the system.
3. In the technical scheme of the invention, the authentication subject is a single electronic version academic calendar and academic degree certificate file, and the certificate states the related identity information of the certifier and the acquisition conditions of the academic calendar and the academic degree, so that the association between the certificate file and the certifier is established. If the content of the certificate file is modified, the certificate can be identified as false by the system, so that the invention can ensure the authenticity and reliability of the content of the certificate file. There is no third party certification authority, all the record of the archive is stored on the platform of the invention, and the function of looking up the certification can be realized by accessing the platform of the invention directly. From the collection of the files, the storage of the files to the review and examination of the files can be completed on the platform of the invention.
It should be noted that, regarding the specific structure of the present invention, the connection relationship between the modules adopted in the present invention is determined and can be realized, except for the specific description in the embodiment, the specific connection relationship can bring the corresponding technical effect, and the technical problem proposed by the present invention is solved on the premise of not depending on the execution of the corresponding software program.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
