Description
Technical field
The present invention relates to block chain security technology areas, in particular to one kind for based on block chain verifying number
The method and system of certificate.
Background technique
As the diversification and information relevant to financial transaction of financial trade method and channel are used for various fields,
Many certificates such as balance of deposits proves that acknowledgment of a debt, bank gurantee, transactions history, financial information statement, mail credit etc. is usually
It is issued by financial institution.
However, client has to go to actual location and requests certificate, this is trouble and time-consuming.
In order to solve this problem, it is provided with the device for receiving the information about requested certificate, including class in the prior art
Type, purpose, client extract at least one certificate corresponding with the information of requested certificate from specific classification account or database
The means of information, creation and storage include the means electronic document bank of the electronic document of certificate information, and by that will be stored in
Digital certificates in library are sent to terminal to issue the means of certificate.
Using the system, the terminal real-time reception certificate at remote location is can be used in client, without physical access
Financial institution.
In general, the seal of financial institution supervisor, embossing seal or seal etc. are used to prove that the certificate of distribution not to be to forge.
Obviously, traditional digital certificates publishing system cannot provide such as seal, emboss official's print of seal or seal etc.
Chapter can determine that issued certificate is true or forges.
However, the problem is solved by the file distribution using conventional watermark technology with Verification System.
In detail, being provided using the document publication of conventional watermark technology and Verification System can issue with insertion watermark
The service of online certificate, and mechanism or company verify the integrality of the online certificate submitted from client and true by extracting
Property.Use the watermark in watermark extraction algorithm insertion certificate.
However, only whether being embedded in by watermark in the case where document publication and Verification System utilize conventional watermark technology
The fact into certificate determines therefore the forgery of document if being embedded in watermark after the certificate of publication, is forged, then
This certificate forged is considered as true certificate, this can bring the problem for keeping system useless.
Summary of the invention
The invention proposes it is a kind of based on block chain verifying digital certificate method the following steps are included:
