Description of the drawings
It, below will be to specific in order to illustrate more clearly of the specific embodiment of the invention or technical solution in the prior art
Embodiment or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, in being described below
Attached drawing is some embodiments of the present invention, for those of ordinary skill in the art, before not making the creative labor
It puts, other drawings may also be obtained based on these drawings.
The electronic invoice stamped signature techniqueflow of Fig. 1 embodiment of the present invention；
The electronic invoice verification technique flow of Fig. 2 embodiment of the present invention；
The electronic invoice of Fig. 3 embodiment of the present invention submits an expense account techniqueflow.
Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, described embodiments are some of the embodiments of the present invention, rather than whole
Embodiment.
Fig. 1 is electronic invoice stamped signature techniqueflow according to the ... of the embodiment of the present invention, as shown in Figure 1, this method includes as follows
Step：
Step S101 selects electronic invoice format to issue invoice.
Specifically, the format of the electronic invoice includes document and picture format.In an alternative embodiment, document
Format uses PDF (Portable Document Format) or OFD (Open Fixed-layout Document) format,
Picture format uses JPG (Joint Photographic Expert Group) or BMP (Bit Map) format.Select electronics
After invoice format, carries out electronic invoice file and issue generation.
Step S102 calculates electronic invoice fileinfo abstract, with after private key encryption and being additional to electronic invoice file.
Specifically, the electronic invoice file generated informative abstract is used into asymmetric encryption using one-way Hash algorithm
After private cipher key pair described information abstract in technology is encrypted, invested in the electronic invoice file as additional information.
In an alternative embodiment, one-way Hash algorithm plucks electronic invoice file generated information using MD5 algorithms
It wants, the encryption of described information abstract is carried out using the private cipher key in the rivest, shamir, adelman of RSA or SM2.For PDF or
For the electronic invoice of OFD document formats, additional information exists as digital signature or remarks content.For JPG or BMP
For the electronic invoice of picture format, additional information is written using digital watermark technology, or will be written with Steganography
The comment field of picture.
The billing information of electronic invoice, informative abstract are uploaded to server-side by step S103.
Specifically, the billing information of the electronic invoice includes：The purchaser of the electronic invoice, seller, invoice generation
Code, invoice number, date of making out an invoice, service name, unit price, quantity, the amount of money, the tax rate, the amount of tax to be paid.Upload the bill letter of electronic invoice
Breath, informative abstract to server-side, server-side record the billing information and informative abstract of electronic invoice.
Fig. 2 is electronic invoice verification technique flow according to the ... of the embodiment of the present invention, as shown in Fig. 2, this method includes as follows
Step：
Step S201 extracts the additional information of electronic invoice.
Specifically, the digital signature or remarks content that the electronic invoice is extracted from document, extract institute from picture
State the digital watermarking of electronic invoice or with the embedded information of Steganography extraction.For the electricity of PDF OFD document formats
For sub- invoice, extraction additional information extracts digital signature or remarks content.For the electricity of JPG BMP picture formats
For sub- invoice, extraction additional information extracts content therein using digital watermark technology, or will be carried with Steganography
Take the comment field of picture.
Step S202 compares electronic invoice informative abstract with public key decryptions additional information.
Specifically, it decrypts the additional information using the Public Key in asymmetric encryption techniques and obtains the electronic invoice
Informative abstract compare the information of the extraction using one-way Hash algorithm by the electronic invoice file generated informative abstract
The informative abstract of abstract and the generation, the authentication failed if the two is inconsistent.If the electronic invoice authentication failed,
The failure information is fed back to purchaser, seller and the authentication of the electronic invoice.
In an alternative embodiment, it is added using the Public Key in the rivest, shamir, adelman of RSA or SM2
The decryption of information, the informative abstract extracted, using MD5 algorithms to electronic invoice file generated informative abstract, described in comparison
The informative abstract of the informative abstract of extraction and the generation, the authentication failed if the two is inconsistent.If the electronic invoice
The failure information is then fed back to purchaser, seller and the authentication of the electronic invoice by authentication failed.
Step S203 verifies the billing information correctness of electronic invoice in server-side.
Specifically, it if the informative abstract of the extraction is consistent with the informative abstract of the generation, is inquired in server-side
The billing information of the electronic invoice, it is described if the billing information of the electronic invoice is correct and there is no reimbursement information
Electronic invoice is verified, if the billing information of the electronic invoice is incorrect or there is reimbursement information, authentication failed；
The billing information that the server-side inquires the electronic invoice includes：The electricity is inquired by the informative abstract of the electronic invoice
The billing information of sub- invoice whether there is.
In an alternative embodiment, server-side uses the billing information of database purchase electronic invoice, informative abstract
It is recorded with reimbursement.In the information that server-side verifies electronic invoice whether correctly and with the presence or absence of reimbursement record, that is, pass through data
Library is indexed the above.
Fig. 3 is electronic invoice reimbursement techniqueflow according to the ... of the embodiment of the present invention, as shown in figure 3, this method includes as follows
Step：
Step S301 verifies electronic invoice.
Specifically, the verification of electronic invoice is carried out using the techniqueflow of Fig. 2.
Step S302 records the reimbursement information of electronic invoice in server-side.
Specifically, after the electronic invoice is verified, the reimbursement information that the invoice is recorded in server-side completes reimbursement.
In an alternative embodiment, server-side uses the reimbursement information of electronic invoice described in data-base recording.
