Description
Technical field
The present invention relates to computer data access technique, more in particular to a kind of for electronic signature account data is concentrated to the method and system of access.
Background technology
Electronic signature is the electronization of traditional seal image, in modern bank business, the seal image on papery signature card is extracted by image processing algorithm, forms electronic image data and preserves.
Utilize image processing algorithm that the seal in bill image and reserved electronic signature are veritified automatically, or indirect labor veritifies, judge seal authenticity, examine for paying the object that foundation is provided thereby reach, this process is electronics print test.
At present, in electronics stamp checking system, seal account data has mainly comprised account essential information and seal electronic data.Wherein, account essential information comprises account, name in an account book, seal card number, enables the date, seal combination etc., exists with character string, date, digital format, takies storage space less; It is larger that seal electronic data takies storage space, mainly comprises: just block/vice card JPEG of seal image, electronic signature are encrypted other image datas (as combination request slip or combination explanation allonge JPEG image) of DAT data, electronic signature BMP figure, seal account etc.Existing electronics stamp checking system is distinguished access to these two classes data, unified being stored in relevant database.Particularly, in existing electronics stamp checking system, the function that relates to seal electronic data with and read-write motion mainly comprise:
One, seal management
Seal is just blocking the extraction for die.Obtain seal by scanner and just blocking JPEG image, just blocking JPEG image from seal and extract electronic signature and encrypt DAT data, electronic signature BMP figure by carrying modulo n arithmetic, again above-mentioned data are stored, be generally stored in relevant database with BLOB or CLOB form.Some stamp checking system can first compress JPEG image, then stores.
Combination request slip or combination explanation allonge describe for the complicated seal combination to account.The combination of seal in electronic signature account is after setting completed, and in order to reduce the storage overhead and transport overhead, existing stamp checking system is not stored these two kinds of images.This step can only the retention of combination request slip or combination explanation allonge geological material carry out.
Whether seal vice card is extracted correct for checking the seal just blocking.Existing stamp checking system obtains seal vice card JPEG image by scanner, read by network the seal of having stored and encrypt DAT data, utilize print test algorithm to carry out the consistance of these two kinds of data of comparison, confirm that whether seal extracts correct, do not preserve the JPEG image of vice card after print test.This step can only the retention of signature card vice card geological material carry out.
