In the present embodiment, when user is traded every time, all can pass through this transaction of preset data library storage
Corresponding Transaction Information.Concrete, this Transaction Information may include that receipt type, transaction number, transaction
Date, payee's name, account, bank of deposit's title, requestee's title, account, bank of deposit's title, with
And currency type and the amount of money etc..
Step 103, signs to this Transaction Information according to default digital certificate, obtains digital signature.
In the present embodiment, for ensureing the effectiveness of electronic receipt, can be by digital certificate to Transaction Information
Sign.Particularly, for safe storage Transaction Information, it is also possible to directly preserve data signature.
Step 104, generates the Quick Response Code that Transaction Information is corresponding with digital signature.
In the present embodiment, step 104 can generate the Quick Response Code that Transaction Information is corresponding with digital signature；
Particularly, in order to reduce the information content of single image in 2 D code, to reduce the requirement of printing precision and to reduce
Identifying difficulty, this step 104 can also generate two Quick Response Codes that Transaction Information is corresponding with digital signature,
This is not restricted.
In the present embodiment, step 104 can directly generate the Quick Response Code that Transaction Information is corresponding；For reducing two
The data volume of dimension code, this step 104 may include that and is compressed compiling to Transaction Information by default compression storehouse
Code, obtains compression information；Generate the Quick Response Code that compression information is corresponding with digital signature.This presets compression storehouse can
To include the compressed encoding of the information such as mechanism, street, this compression storehouse can also need to be updated according to user,
This is no longer going to repeat them.
Step 105, is back to user terminal after generating the electronic receipt recording this Transaction Information and Quick Response Code.
In the present embodiment, the electronic receipt generated by step 105 can only record Transaction Information and two dimension
Code；In order to distinguish different transaction, and preventing receipt from reusing, this electronic receipt can also record electronics
Receipt number, concrete, this step 105 includes: obtain, according to preset rules, the electronics that this Transaction Information is corresponding
Receipt number；User it is back to eventually after generating the electronic receipt of record electronic receipt number, Transaction Information and Quick Response Code
End.
There is advantages that owing to digital certificate has act of law, therefore make digital certificate
The digital signature obtained of signing Transaction Information has act of law, i.e. records Transaction Information and numeral is signed
The electronic receipt of the Quick Response Code that name is corresponding is effective.The technical scheme that the embodiment of the present invention provides, it is only necessary at electronics
Receipt carries out signature by digital certificate before generating can ensure the effectiveness of electronic receipt, generates electronic receipt
During participate in without artificial, be difficult to forge, solving the seal of electronic receipt in prior art needs people
Work is added a cover, and not only wastes time and energy, and the problem being easier to forge.Additionally, the program makes user to lead to
Cross Quick Response Code the verity of electronic receipt is verified, simple to operate.
