Description
Technical field
It can avoid leaking other people moneys by block chain technology the present invention relates to one kind, and can verify that the electronic document true and false
And label originator identity, and investigated using the universal electric file using block chain that electronic document Hash Value searches stamped signature person
System and method.
Background technique
In general, electronic document is because being easy duplication and altering, it is more difficult to file label originator status is confirmed, so that being permitted
More open files proved of such as diploma, vocational certificate, contract document, visa etc. tool all or with hard copy print and add
Chapter voucher affix one's seal to give by card person or contract to making, but hard copy certificate is with high costs, can not transmit quickly like electronic document,
Also because being limited to a money protection, publisher can not reveal a money by card person, cause the third party to check difficult, so that pseudo-
Certificate event is made still to emerge one after another so far.Such as diploma, after organ, school authorizes diploma to graduate, graduate
When interviewing to company's line number and its diploma is provided, interviews unit and can not understand the true and false for investigating its diploma, and face
If trying organ, unit direct access inquiry school, organ, school can not reveal for fear of a money protection correlation method rule.
Therefore Bian You school releases the technology distinguished using block chain technology as the certificate true and false, but block chain card at present
Book system all belongs to dedicated closed system, and other unit is not available, if main cause is that will not have can by other unit verifying
Reliability.For example, the block chain diploma system of Culture University is only able to verify that the academic certificate of Culture University, it is not able to verify that American South
The academic certificate of increasing, the academic certificate of Southern Canada are not that Culture University is signed and issued, and verification result is certainly insincere.Therefore A
University system is only able to verify that the certificate of A university, and the system that B university is not available A university will allow third party examination person to believe that B is big
Certificate, it is necessary to be the block catenary system of B university exploitation.Again or a Bureau of Education, counties and cities system, the school of other counties and cities
Be not available, and or the Ministry of Education academic block catenary system, can not verify traffic unit driving license, row shine authenticity, and or
The academic block catenary system of one Ministry of Education of the state, the Ministry of Education of other countries are not available simultaneously.Such block chain diploma system
Because can not be general, constituent parts must be set up a set of one's own system, but only global up to ten million school just needs
Up to ten million block chain diploma systems is built, the license of the public and private unit distribution of more let alone the other points will form the serious consumption of resource
Take.Furthermore block chain data checking technology at present, it is necessary to submit block chain transaction serial number just to find, if only submitting electronics
File simultaneously can not find out block chain data, but serial number of trading has the risk of loss to find out stamped signature originally once losing and write
The block chain data entered, like looking for a sand marine greatly, as a consequence it is hardly possible to.Even if there is the certificate of electronic document at this time, because
It can not check, equal to having lost certificate.
When having multidigit stamped signature person for a identical electronic document, technology just must to check block chain data at present
Multiple transaction serial numbers must be obtained, then search stamped signature person one by one, efficiency is extremely low, can not also be confirmed whether all stamped signature persons
It is all complete, computer is bought for example, purchasing by group contract and arranging ten people in certain time limit, then 5,000 yuan are made a price reduction for every, even if having really
Ten people stamped signature and are written in block chain within the time limit, but forget to submit transaction serial number after people's stamped signature because having, and the time limit is then only
Nine people's stamped signatures are can confirm that, it is invalid to lead to purchase by group contract, causes antipodal as a result, certainly will cause Transaction Disputes.
Therefore, a kind of new technical solution is needed to solve the above problems in the prior art.
