Description
Technical field
The invention belongs to financial field electronic certificate technical field, in particular to a kind of electronic certificate digital signature and verifying
Method and system.
Background technique
With the fast development of Internet technology, the papery transaction certificate of various industries gradually turns to the direction of electronization
Become.And in financial industry, due to the particularity of industry, at present in bank outlets' transacting business, various business transactions
Voucher is very more, agreement, application, business voucher etc., often completes a business, various papery vouchers few then two or three
, more then five or six.This papery voucher both not environmentally, was also not easy to take care of.When subsequent client has objection to transaction, warp
Often cause to handle unfavorable status in the legal dispute of client and interbank due to lacking original business voucher.Simultaneously because paper
The keeping of matter voucher is difficult, and the content on papery voucher is easy distortion after a long time, while papery voucher is easy to be tampered forgery,
It is created great difficulties to law evidence obtaining.
In internet+epoch, internet has all been docked in the various consumption of daily life, and people are increasingly accustomed to electronics
Change office, everybody also increasingly accepts daily various businesses voucher electronization, such as electronic invoice, electronic bill payment bill
Deng.
Bank outlets' intellectualized reconstruction has been the mainstream transition direction in current industry, and intellectualized reconstruction is mainly site
High cube container is removed, gradually the business handled on sales counter originally is transferred on intelligent equipment and is handled.Business is handled by original
Manually handle and be changed to intelligent equipment and handle, this inevitable requirement must be made using electronic certificate to say when substituting original transacting business
Papery voucher can provide more friendly business experience to client in this way.
Business voucher is the voucher with legal effect of client's transacting business, substitution of the electronic certificate as papery voucher
Product, with same legal effect, this requires electronic certificate content generated must be complete, at the same have it is anti-tamper, prevent
It denies, it may be verified that the features such as.
Summary of the invention
