Description

Academic achievement pre-publishing table and right authentication system and method based on block chain

Technical Field

The invention relates to an academic achievement pre-publishing table and right authentication system and method, in particular to an academic achievement pre-publishing table and right authentication system and method based on a block chain, and belongs to the technical field of block chain application.

Background

The significance of the release of academic achievements lies in better promoting the progress of the academic, and on the basis that the inventor approves the achievements in the research field, the essence is absorbed, the innovation is developed, and the waste of time and energy cost of repeated academic research is avoided. However, with the exposure of academic misbehavior during the course of one-time academic hacking and fund project application, people are made aware of the importance of enhancing the protection and correcting the academic attitude of academic achievements.

Typically, a paper takes anywhere from a few months to a year from submission to release. During this period, the editing of the publications transfers the academic achievement of the contributor to the colleagues in the academic world for review, and the contributor needs to modify his/her contribution repeatedly until the colleagues can not find out the fault. Even with the tremendous efforts of the contributors, there is still a significant chance of being rejected. At this time, it is necessary to replace a publication and repeat the lengthy and difficult posting process. The traditional contribution process has another big disadvantage: the research result of A is delivered to peer reviews, the time required by the peer reviews is uncertain, and the official publication can take one or two years. If during this period B completes and issues the study at a faster rate, the outcome of the study may not be that of A. There is even the possibility of: after seeing the manuscript, the manuscript reader of A feels good thinking, changes the thought from the original one by one, and places are changed to give out the result of A in advance. This is not uncommon in academia.

Therefore, the time required for disclosing the achievement is shortened, the probability of repeatedly researching the same problem by different students is reduced, and malicious competition such as plagiarism at innovation point, paper emergency issue and the like is reduced, so that the method becomes a problem which is highly concerned and needs to be solved urgently. Just like other intellectual property rights, how to prove the integrity, legitimacy and time of production of an academic achievement, to protect the legitimate interests of a party from infringement, this has resulted in methods such as digital signatures, time stamping services, etc., but these methods, without exception, require the involvement of authentication by a third party trusted authority, which, if hacked, or the legitimate interests of the party will be infringed by the voluntary tampering action of the third party authority, in 2008, the blockchain technology accompanied with the appearance of bitcoin realizes decentralized service from the aspect of mathematics and cryptography for the first time, does not need the participation of a third party organization, reliably and safely realizes the generation and transaction of the currency, the lack of trust in third party agencies, has led to an increasing demand for decentered services, however, no services are available that provide proof and assurance of the decentralised academic achievement.

Aiming at the defects and the block chain in the existing academic achievement release process, the method has the characteristics of centralization, distributed collective maintenance, data time sequence, high safety and reliability. How to use the block chain to perform the operation of right confirming and authorization on the academic achievement is the subject to be solved by the field.

The following presents a simplified summary of the basic concepts and embodiments of the invention in a simplified form to provide a basic understanding of some concepts in a more detailed description that follows. This summary is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.

In order to achieve the purpose, the invention adopts the following technical scheme:

the first scheme is as follows: a block chain based academic achievement pre-publishing and right authentication system comprises a user interaction module, a feature extraction module, an original detection module, an Algorand public block chain interaction module and a work storage module;

the user interaction module is used for managing users, registering accounts of unregistered users, distinguishing common users and administrators through different authorities, providing a visual operation interface for the users, and uploading academic works;

the feature extraction module is used for compressing the academic works through a feature extraction algorithm, then converting the compressed academic works into character strings for hash operation to obtain a fixed-length hash value, and transmitting the hash value to the block chain;

the originality detection module extracts the academic works and the related works, compares the similarity, judges whether the academic works are original according to the similarity, rejects the uplink of the works which do not pass the examination and automatically replies the reason why the user rejected the works;

the Algorand public block chain interaction module is used for designing intelligent contracts with different mechanisms according to requirements, a user protects own academic works through a protocol established on the block chain, and the academic works audited by the original detection module are automatically recorded in the block chain;

and the work storage module is used for storing the academic works audited by the original detection module into the distributed database.

Further: the system also comprises a task management module, which is used for tracking the processing progress and the process of the task and is responsible for the full life cycle from creation to beginning to end of the task.

Further, the method comprises the following steps: the system also comprises a right management module which is responsible for generating and managing the whole life cycle of the certificate storage, including the processes of establishing the certificate storage, updating the certificate storage and failing to store the certificate.

Scheme II: a academic achievement promulgation and right authentication method based on a block chain is realized based on a scheme I, a user registers in a real-name system, and user account password data is stored in a local database; after logging in, the user links up his work by clicking to upload; compressing the works by a feature extraction algorithm, then converting the compressed works into character strings for hash operation to obtain a fixed-length hash value, transmitting the hash value to a block chain, simultaneously storing original works into a database, checking the weight in the uploading process, checking whether the uploaded works are stored by the chain, determining that the uploaded works are not required to be protected or are similar to the works in the database, and preventing plagiarism piracy; if the works do not pass the system audit, the uplink is rejected, and the reason for rejection is returned to the user; and the works are automatically linked up through checking and reviewing, and an electronic certificate is issued to the user.

Further, the method comprises the following steps: the academic achievement pre-publishing table and right authentication method based on the block chain comprises the following specific steps:

step 1: establishing a decentralization academic achievement right authentication system facing the user learner by utilizing an Algorand public block chain platform; designing protocols with different mechanisms according to requirements, and protecting the academic works of the users through the established protocols on the block chain network;

step 2: the user performs real-name registration through the user interaction module, data such as user account passwords and the like are stored in a local database, and after login, the user can browse academic works of other users on the platform and upload and register own academic works_；

Step 3: after uploading the academic works to a background, a user carries out feature extraction through a feature extraction module, firstly, an original academic work is processed through a SimHash algorithm, and finally, a file is converted into a 64-bit Hash value which is a unique feature value corresponding to the academic works;

step 4: checking whether the characteristic value exists in the existing certificate through an original detection module, if the characteristic value does not exist repeatedly, determining that the work is not repeatedly uploaded, storing academic work information to a chain, and then storing a returned transaction ID as an index; rejecting uplink if similar characteristic values are found;

step 5: and after the academic work information is stored in the block chain, the academic work original elements are stored in the server without compression, so that the academic work information can be used as evidence.

Further, the method comprises the following steps: an interplanetary file system IPFS is adopted, and meanwhile, specific information and remarks of academic works are stored, and the IPFS generates a unique address for each work for access; IPFS is a decentralized peer-to-peer hypermedia distribution protocol, which provides a different hash value for each uploaded academic work, and then addresses the academic works stored on the network according to the hash value, wherein the hash value is generated according to the content of the academic works by using a cryptographic hash algorithm. This unique hash value eliminates redundancy in the network, ensuring that no identical files are uploaded a second time. By using IPFS, the size of the information stored on the blockchain is saved a lot.

Further: the protocol comprises an entitlement registration protocol and an entitlement query protocol, and after the entitlement information registration is effective, the index of the entitlement and the stored block number information are stored in a database so as to facilitate subsequent searching and searching.

The invention achieves the following effects:

firstly, by utilizing the characteristic that the block chain is based on internet access, the academic achievement can be linked up immediately when being formed, and the problem of time delay of the traditional academic achievement release is solved, so that the first release right of the academic achievement is put into place, and the right attribution problem of the academic achievement is greatly reduced.

And secondly, by utilizing the characteristic of decentralized block chain, the influence of human factors in the academic work publishing and disclosing process is eliminated, the risk of academic plagiarism or result leakage in the reviewing process is eliminated, the problem of distrustment to a third-party platform is solved, and the pureness of work publishing is ensured.

And thirdly, by utilizing the characteristics of incapability of tampering, openness and transparency of the block chain and the like, the permanent retention and incapability of tampering of the cochain process of the academic works are ensured, and the problem of credibility of data is solved.

And fourthly, compared with the traditional public chain bitcoin network and EtherFang, the selected public chain Algorand has more outstanding advantages. The Algorand adopts a consensus algorithm combining the Byzantine protocol and the rights and interests certification, adopts a randomized verification mode to generate blocks, ensures the security and is irrelevant to the computing resources owned by the nodes, so that a large amount of computing waste is not needed, and the power resources are saved.

Because the Algorand adopts the rights and interests certification and drawing mode, even if the Algorand has more money, the Algorand can be diluted by the following people, compared with the improvement of worthless computing power, the Algorand block chain system has higher stability of decentralization, and the lower maintenance cost ensures the sustainable development of the community.

The Algorand protocol has no miners, all users have the opportunity to participate in the generation of new blocks, a new block can be generated every ten seconds, and only one honest block can be generated due to drawing, so that the bifurcation problem is successfully avoided.

And fifthly, the storage scheme adopted by the application has better safety performance. A distributed and networked file system is adopted to meet the requirement that any node on a network can be connected with the storage system to form a unified decentralized whole when block chain application and intelligent contracts are further constructed in the later period.

Sixth, the work file is saved by an interplanetary file system (IPFS). IPFS is a file system based on content storage, and it uses a hash value of content as an address, and verifies whether the hash value matches the address when the content is fetched, so that file data is strongly tamper-resistant when using IPFS. In addition, the intelligent contract stores the address of the IPFS of the file and the hash value of the file, and can verify the authenticity of the data of the file again after the data is taken out from the IPFS, so that the security of file storage is guaranteed by preventing the file from being tampered by a background administrator.

For the convenience of understanding of the embodiments of the present invention, the following detailed description will be given by way of example with reference to the accompanying drawings, and the embodiments are not limited to the embodiments of the present invention. Those of ordinary skill in the art will understand that: the figures are schematic representations of one embodiment, and the blocks or processes shown in the figures are not necessarily required to practice the present invention.

Example 1: the academic achievement pre-publishing and right authentication system based on the block chain comprises a user interaction module, a feature extraction module, an original detection module, an Algorand public block chain interaction module, a work storage module, a task management module and a right management module;

the user interaction module is used for managing users, registering account numbers of unregistered users, distinguishing common users and managers through different authorities, providing visual operation interfaces for the users, and uploading academic works;

the characteristic extraction module compresses the academic works through a characteristic extraction algorithm, converts the compressed academic works into character strings for Hash operation to obtain a fixed-length Hash value, and transmits the Hash value to the block chain;

the Algorand public block chain interaction module is used for designing intelligent contracts with different mechanisms according to requirements, protecting the academic works of a user through a protocol established on the block chain by the user, and automatically recording the academic works audited by the original detection module to the block chain;

the work storage module is used for storing the academic works audited by the original detection module into a distributed database;

the task management module is used for tracking the processing progress and process of the task and is responsible for the full life cycle of the task from creation to beginning to end;

the right management module is responsible for generating and managing the whole life cycle of the certificate storage, including the processes of establishing the certificate storage, updating the certificate storage and failing to store the certificate.

Example 2: the academic achievement pre-publishing table and right authentication method based on the block chain comprises the following specific steps:

step 1: the academic achievement pre-release and right authentication system based on the block chain is characterized in that a public chain block chain platform is utilized, if the building operation of the system can be carried out through Algorand, the academic achievement pre-release and right authentication system based on the block chain comprises a user interaction module, a feature extraction module, a block chain interaction module, an original detection module and a work storage module.

Step 2: the user performs real-name registration through the user interaction system, data such as user account passwords and the like are stored in a local database, and after login, the user can browse academic works of other users on the platform and upload and register own academic works.

Step 3: after a user uploads a file to a background, feature extraction is carried out through a feature extraction module, the original file is firstly processed through a SimHash algorithm, and finally the file is converted into a 64-bit Hash value which is the unique feature value corresponding to the work.

Step 4: after the characteristics of the new works are extracted as hash values, whether the characteristic values exist in the existing storage certificates is checked through an original detection module, if the characteristics do not exist repeatedly, the works are determined to be non-repeatedly uploaded, the information of the works is stored on a chain, and then the returned transaction ID is stored as an index; and rejecting the uplink if the similar characteristic value is found.

Step 5: after the information of the work is stored in the blockchain, original pieces of the work must be stored in a server without compression so as to be used as evidence. The invention adopts an interplanetary file system IPFS, stores the specific information and remarks of the works, and generates a unique address for each work for access. IPFS is a decentralized peer-to-peer hypermedia distribution protocol that is also referred to as content addressable by providing a distinct hash value for each file that is uploaded, and then addressing the files stored on its network according to the hash value, i.e., the hash value is generated from the file content using a cryptographic hash algorithm. This unique hash value eliminates redundancy in the network, ensuring that no identical files are uploaded a second time. By using IPFS, the size of the information stored on the blockchain is saved a lot.

After the user submits the evidence-storing task to the system, the task management module tracks the processing progress and process of the task and is mainly responsible for the whole life cycle of the task from creation to beginning to ending. And after monitoring that the uplink task is processed, sending a message to the authority management module to create a new deposit certificate and sending a completion prompt to the front end. The right management module is responsible for generating and managing the whole life cycle of the deposit certificate, such as the processes of creating the deposit certificate, updating the deposit certificate, losing the deposit certificate and the like.

The functions of querying and registering works used by the user are realized through the self-designed protocol of the invention. The set of protocols are upper-layer applications which are operated on the blockchain network and are constructed based on the blockchain operation rule, and a set of protection and application protocols for academic works is established based on the blockchain network and the characteristics, the structure and the like of the blockchain network, and the protection and application protocols comprise an entitlement registration protocol and an entitlement query protocol.

Referring to the rights registration protocol, the following is a description of the rights generation process for a new work: firstly, a user submits a work original with user information to an agreement, then the agreement extracts fingerprint information of the work according to the work original, and the fingerprint information is combined to form a JSON character string containing the work, author information, work effective time and agreement type. And submitting the uplink service to package and send the user work information to a block chain in a transaction form, then creating a new transaction by using the API of Algorand according to the protocol, setting the transaction type as Transfer, setting the sender and the receiver of the Transfer as a fixed protocol preset address, and fixing the Transfer amount to 0 Algo. Thus, the transaction can be waited for confirmation only by paying the confirmed handling fee, and the confirmation process is the process of examining the work by the system. After the system confirms that the work is qualified, the JSON character string is packaged to a Note field of the transaction, and therefore a block chain transaction containing evidence storage information is formed.

And after the transaction is generated, the transaction is sent to a block chain, and the transaction is packaged into a transaction list by a certain block and then confirmed. When the block is formally confirmed to be valid, the right information of the certificate in the protocol is valid at the same time. The process flow for submitting uplink services is shown in fig. 1.

For works that have been certified for registration on the Algorand blockchain, it is usually possible to find their index directly in a database outside the blockchain and then extract this blockchain certification record from the index. But for other applications that require a lookup directly on the blockchain, a search is required over the entire blockchain network.

According to the requirement, an entitlement query protocol is designed: the query process is as shown in fig. 2, the content to be queried submitted by the user is received at the beginning of the protocol, which may be user account information or work fingerprint information, and these values can be obtained by performing a second search in the database. After the protocol obtains the information to be checked, the protocol requests the block chain network for the current newest block, namely the block pointed by the current head pointer, and the block content is obtained according to the hash pointer. The block is mainly transaction lists Transactions, and the Note information fields are extracted one by one in each transaction by traversing the lists. Since the Algorand block chain is a public chain, the Note information of each transaction thereof is stored with information that may be filled out by many other persons. Therefore, in the matching process, whether the address comes from the protocol is judged according to the Sender field and the Receiver field, and the Application field can also be used for verifying whether the address is the deposit content submitted by the protocol. If the protocol content is confirmed, then the Signature or the user field is obtained from the protocol content for matching, and if the protocol content is consistent, the query result is returned.

If all the blocks are searched until the searched record is not matched, the record for verifying the work does not exist on the whole block chain.

Compared with the traditional public chain bitcoin network and Ethengfang, the public chain Algorand selected by the application has more outstanding advantages. The Algorand adopts a consensus algorithm combining the Byzantine protocol and the rights and interests certification, adopts a randomized verification mode to generate blocks, ensures the security and is irrelevant to the computing resources owned by the nodes, so that a large amount of computing waste is not needed, and the power resources are saved.

The conventional block chain system has poor expansibility, one block is generated by a bit coin in ten minutes, only 3-4 transactions can be processed per second, and the actual requirement cannot be met. Because the calculation result is uncertain, the traditional block chain system has higher bifurcation probability and slow transaction confirmation. The Algorand protocol has no miners, all users have the opportunity to participate in the generation of new blocks, a new block can be generated every ten seconds, and only one honest block can be generated due to drawing lots, so that the bifurcation problem is successfully avoided, no bifurcation accident occurs until the operation is finished, and the bifurcation risk is low as proved by a mathematical model. This is why we chose Algorand as the underlying platform for this study.

The storage scheme adopted by the application has better safety performance. The existing copyright protection systems directly realize the storage mode of uploaded works on a server or a specially built local storage system thereof. This approach results in cumbersome local directory management and takes up server space. Due to the requirement of a system constructed by a distributed network such as a block chain, the distributed and networked file system is adopted, so that the requirement that any node on the network can be connected with the storage system to form a unified decentralized whole when block chain application and intelligent contracts are further constructed in the later period is met. In this scenario, the present application employs an interplanetary file system (IPFS) to store the work file. IPFS is a file system based on content storage, and uses a hash value of content as an address, and verifies whether the hash value matches the address when the content is fetched. In addition, the intelligent contract stores the address of the IPFS of the file and the hash value of the file, and can verify the authenticity of the data of the file again after the data is taken out from the IPFS, so that the security of file storage is guaranteed by preventing the file from being tampered by a background administrator.

From the above description of the embodiments, it is clear to those skilled in the art that the present invention can be implemented by software plus necessary general hardware platform. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which may be stored in a storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the method according to the embodiments or some parts of the embodiments.
