Problems solved by technology

The above verification methods can only be verified online, and the electronic certificate issuer can only be identified by a unique code, so there is a suspicion that the illegal electronic certificate issuer steals other people's codes for invoicing
In addition, there is no verification of the identity of the tax authority, and there are certain loopholes in the phenomenon of posing as a tax authority to issue invoices.

Embodiment 1

[0189] figure 1 It is a flow chart of the method for generating a blank electronic certificate provided in the first embodiment of the present invention. The method for generating a blank electronic certificate provided in this embodiment is used to generate a blank electronic certificate, such as figure 1 As shown, the method includes:

[0190] Steps for generating blank electronic credential identification information (step 101 to step 103):

[0191] Step 101: Generate first electronic certificate information based on at least the electronic certificate face information among the preset electronic certificate face information, electronic certificate face information, electronic certificate issuer public key, and electronic certificate issuer name;

[0192] The electronic voucher face information includes one or any combination of two or more of the following information:

[0193] Electronic certificate code, electronic certificate number, electronic certificate type, name ...

Embodiment approach

[0220] The step 103 further includes: generating a blank electronic certificate together with the first electronic certificate information, the public key of the electronic certificate issuing authority, the signature of the issuing authority, and the public key of the issuing party of the electronic certificate;

[0221] The electronic credential authority public key is a valid public key corresponding to the private key issued by any authority. The generation and issuance of the public and private keys of the electronic certificate authority and the public and private key of the electronic certificate issuer can be completed by the electronic certificate authority itself, or can be entrusted to a trusted third-party organization.

[0222]It can be seen that in this embodiment, the blank electronic certificate is any combination of the first electronic certificate information, the public key of the electronic certificate issuing authority, the signature of the issuing authorit...

Embodiment 2

[0236] figure 2 It is a flow chart of the method for generating a valid electronic credential provided in the second embodiment of the present invention. The method for generating an electronic credential provided in this embodiment is used to generate a valid electronic credential, such as figure 2 As shown, the method includes:

[0237] Step 201: The electronic certificate issuer generates second electronic certificate information for describing the specific content of the electronic certificate;

[0238] The second electronic credential information is used to describe the specific content of the electronic credential, including but not limited to the time when the electronic credential was issued, the buyer’s name, the buyer’s identification number, the buyer’s address, the buyer’s phone number, the buyer’s bank, and the buyer’s account number , product name, labor service name, service name, specification model, unit, quantity, unit price, amount, tax rate, tax amount, ...

Abstract

The invention discloses an electronic evidence generation and public verification method, device and system. The electronic evidence generation method comprises a valid electronic evidence identification information generation step, a fourth electronic evidence information generation step, a fourth electronic evidence information verification step, a fifth electronic evidence information generation step, an issuing authority second signature generation step and a valid electronic evidence generation step. According to the method, after an issuing authority is utilized to verify all information, a new signature is made to replace a previous signature, therefore, anti-falsification, sharing prevention and incompliant usage prevention of electronic evidence are improved, the public verification process is simplified, and only the signature of the issuing authority needs to be verified. Through the method, the anti-falsification of the electronic evidence is enhanced, the defects that in the prior art, someone pretends to be the issuing authority to issue the electronic evidence, different electronic evidence issuers share the electronic evidence, and the electronic evidence is used incompliantly are overcome, and the verification difficulty of the electronic evidence is lowered.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method, device and system for generating and publically verifying electronic credentials. Background technique [0002] With the development of Internet electronic transactions, financial auditing, and enterprise informatization, it has become a trend to use paperless electronic vouchers for payment, settlement and accounting in the process of business data transfer, and electronic vouchers are gradually replacing traditional paper vouchers. , the application is more and more extensive. Electronic certificates are based on computers and modern communication technologies, store information in the computer system in the form of data, and realize the functions of traditional paper certificates through network transmission. [0003] At present, there are many kinds of vouchers in circulation, such as invoices (ordinary invoices, value-added tax invoices, and quota invoices is...
