Description
Technical field
The present invention relates to computer data access technique, more particularly, it is related to a kind of be used for electronic signature account
The method and system accessed in data set.
Background technology
Electronic signature is the electronization of traditional seal image, in modern bank business, by the seal on papery signature card
Image is extracted by image processing algorithm, is formed electrical image data and is preserved.
The seal in bill image and reserved electronic signature are veritified automatically using image processing algorithm, or auxiliary
It is artificial to veritify, judge seal authenticity, so as to reach to pay the purpose that examination ＆ verification provides foundation, this process is electronics print test.
At present, seal account data mainly contains account essential information and seal electronization number in electronics stamp checking system
According to.Wherein, account essential information include account, name in an account book, seal card number, enable the date, seal combination etc., with character string, day
Phase, number format are present, and it is smaller to take memory space；Seal electronic data occupancy memory space is larger, mainly includes：Seal
Positive card/vice card JPEG images, electronic signature encryption DAT data, electronic signature BMP figures, other image datas of seal account（Such as
Combine request slip or combination explanation allonge JPEG images）Deng.Existing electronics stamp checking system is not deposited to this two classes data as differentiation
Take, be uniformly stored in relevant database.Specifically, in existing electronics stamp checking system, it is related to seal electronization number
According to function and its read-write motion mainly include：
First, seal management
Seal is just blocking the extraction for stamp.Seal is obtained by scanner and is just blocking JPEG images, by carry modulo n arithmetic from
Seal, which is just blocking, extracts electronic signature encryption DAT data, electronic signature BMP figures on JPEG images, then above-mentioned data storage is got up,
Relevant database is typically stored in BLOB or CLOB forms.Some stamp checking systems first can be compressed to JPEG images, then
Storage.
The complicated seal combination that combination request slip or combination explanation allonge are used for account illustrates.In electronic signature account
After seal combination settings in family finish, in order to reduce the storage overhead and transport overhead, existing stamp checking system is not to this
Two kinds of images are stored.The step is carried out in which can only illustrate the retention of allonge geological material in combination request slip or combination.
Whether the seal extraction that seal vice card is used to check on positive card is correct.Existing stamp checking system is printed by scanner
Reflected vice card JPEG images, and the seal stored is read by network and encrypts DAT data, compares both numbers using print test algorithm
According to uniformity, confirm seal extraction it is whether correct, the JPEG images of vice card are not preserved after print test.The step can only print
Carry out to the retention of mirror card vice card geological material.
2nd, bill is veritified
During bill is veritified, the seal stored is obtained by network transmission and encrypts DAT data, is calculated using print test
Method veritifies the true and false of seal on bill.
