Description
Technical field
The present invention relates to Internet technical fields, and in particular to a kind of learning records method and dress based on block chain technology
It sets.
Background technique
Current many schools have begun use information tutoring system and impart knowledge to students, and Informalized teaching system teaches tradition
Scientific principle is read and is combined with information technology.Teacher is imparted knowledge to students using Informalized teaching system, can be substantially reduced labor intensity, be mentioned
High teaching efficiency.However, existing tutoring system often can not be grasped and be tracked to the learning behavior of student, it can not be timely
The study situation data of student are conducted further analysis and recorded.HireRight has found that there are about 86% in an investigation
Company pass through educational background there are job hunter and fake and obtain interview or even the case where employed.False evidence, false credentials are spread unchecked, and are made
False at low cost, several hundred pieces can customize a university diploma, know people's employment to enterprise and cause serious puzzlement, low quality people
It just adulterates and baneful influence also is caused to elite school's reputation, and the civil order for praising highly fair competition is brought and is chosen
War, such as once there is the people of educational level of primary school to make Tsinghua University's diploma and applied for top managers and passed through interview and examined
It looks into, is just penetrated in the trial period, economic loss and bad social influence are caused to enterprise, we value the strength of the talent
But sincere trampleed on must not be allowed.
In Informalized teaching system or teaching management practice before this, the learning records of usual each learner are dispersions
It saves, some are stored in the archives of learner, are responsible for safeguarding by each school oneself and be taken care of.Due to learner
It practises record to be dispersed in different schools, there are school administrator's carelessness, and archives of paper quality to be caused to be lost or school's server
The possibility for causing electronic data to be lost by attack.In addition, many on-line study, vocational trainings etc. all can not be recorded effectively.Cause
This is recorded now for the incomplete student of these dispersions, and learner is very inconvenient in access or use.
It is new by looking into, 1 patent related to the present invention is retrieved, it is a kind of base of Chinese patent CN108121498A-
In the method and apparatus that the learning records of block chain technology save, the specific method is as follows disclosed in it in above-mentioned patent: obtaining
At least one learning records in the study stage of learner；First Hash operation generation is carried out to learning records obtained
Corresponding first cryptographic Hash；Encryption is carried out to first cryptographic Hash using preset private key and generates corresponding signature；To described
Signature carries out the second Hash operation and generates corresponding second cryptographic Hash；Second cryptographic Hash and learning records obtained are protected
It is stored in current block.
According to it is above-mentioned look into it is new, existing method the problem is that: block chain is temporally established for learner, all records are not
It on the same chain, is runed counter to mainstream block chain technology, and single chain is too short, data tampering easy to accomplish fails to embody block
The advantage of chain technology.
Summary of the invention
The object of the present invention is to overcome the problems of the prior art, provides a kind of study note based on block chain technology
Recording method and device realize the whole learning records for saving learner's whole life cycle, and ensure that learner learns note
The safety of record can not be distorted and can not be forged.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme:
A kind of learning records method and apparatus based on block chain technology, method includes the following steps:

Step 2 Peer node verifies learning records LR by intelligent contract respectively, participates in the Peer node endorsed for implementing result
Return to application program；
Step 3) record initiator's application program collects endorsement result and Orderer service node is submitted in result broadcast；
Step 4) Orderer service node executes common recognition process and generates the new data block with learning records LR, confirmation
Learn block chain on the block of recording areas afterwards, Peer node is distributed to by message channel；
Step 5) Peer node is respectively verified after learning records LR and is submitted in local account book, entire block chain network
Practise the record same the end of the step of data.
Further, the certificate authorization center CA in the step 0) includes responsible educational institution and educational institution, described
Responsible educational institution is the Ministry of Education or Bureau of Education, and the educational institution is school, online education mechanism or non-online education mechanism.
