In this embodiment, after confirming that the content, format and various types of chapters in the to-be-verified and polled license are correct, the terminal of the auditor may add information of the auditor to the to-be-verified and polled license, for example, add a official chapter of the auditor (for example, a official chapter of a financial institution), a signature, a time for the auditor to pass the audit of the to-be-verified and polled license, and so on, thereby obtaining the verified and polled license.
Optionally, if the terminal of the auditor confirms that the content, the format and at least one of the various types of chapters in the to-be-audited inquiry function have errors, the terminal of the auditor can directly link and broadcast the message which is not audited by the to-be-audited inquiry function without adding information of the auditor to the to-be-audited inquiry function.
S204, encrypting the checked and verified inquiry letters to obtain inquiry letter ciphertext, and carrying out associated uplink storage on the inquiry letter ciphertext and the check and verification letters to be checked for inquiry by a check and requirement party.
The check ciphertext is ciphertext obtained after the checked check is encrypted.
Optionally, in order to ensure the security of the checked and verified license stored on the blockchain, in this embodiment, the terminal of the checking party may encrypt the checked and verified license, and the obtained encrypted and corresponding check ciphertext of the checked and verified license. Optionally, the verified verification letter can be encrypted by adopting a privacy certification method, and the obtained verification letter ciphertext corresponding to the encrypted verified verification letter can be obtained.
In order to facilitate the subsequent search of the block comprising the check ciphertext in the blockchain network, in this real-time example, an association relationship between the check ciphertext and the check to be verified can be established, the check ciphertext, the check to be verified and the association relationship between the check ciphertext and the check to be verified are stored together in the blockchain network, so that the subsequent verification demander can conveniently search the check ciphertext in the blockchain network based on the check to be verified.
Optionally, an association relation between the query function ciphertext and the identification of the to-be-checked query function can be established, the query function ciphertext, the identification of the to-be-checked query function and the association relation are stored in the blockchain network together, and a follow-up checking demander can conveniently search the query function ciphertext in the blockchain network based on the identification of the to-be-checked query function.
According to the verification method of the verification function, firstly, the verification request of the verification function sent by the verification demand party is responded to, and the verification function to be verified is obtained; checking the check letter to be checked; if the verification passes, adding the information of the auditor to the to-be-verified and verified certificate, and obtaining the verified and verified certificate; and encrypting the checked and verified inquiry letters to obtain inquiry letter ciphertext, and carrying out associated uplink storage on the inquiry letter ciphertext and the check and verification letters to be checked for inquiry by a check and requirement party. Obviously, the security of the checked and verified check is ensured by encrypting the checked and verified check, and the check of the checked and verified check is carried out on line, so that the check process of the check is carried out in a mode of manually mailing the check or a parent check mode, the labor cost and the audit time can be reduced, and the audit efficiency is improved. In addition, the application carries out the associated uplink storage of the query ciphertext and the query to be checked, can facilitate the subsequent tracing, can prevent the query ciphertext and the query to be checked from being tampered, and ensures the security of the query ciphertext and the query to be checked.
Based on the above embodiment, this embodiment provides an alternative implementation manner of obtaining the checked and verified certificate, specifically as shown in fig. 3, including the following steps:
And S301, signing the inquiry function to be audited according to the private key of the auditor to obtain the digital signature of the auditor.
The digital signature is a section of digital string which is obtained by encrypting information data by an auditor and cannot be forged by other people, the section of digital string is an effective proof for the authenticity of information sent by the auditor, and the digital signature is similar to a common physical signature of a paper version.
Alternatively, a private key refers to a key that is owned by itself, which is typically used to encrypt a session key, verify a digital signature, or encrypt data that can be decrypted with a corresponding public key.
In this embodiment, a private key of an auditing party may be used to encrypt specific content or all content in a to-be-audited certificate, so as to obtain a digital string related to the content, and the digital string is used as a digital signature of the auditing party, where the specific content may include a official seal and an asset of an audited object.
S302, the digital signature and the verification passing time of the auditor are used as auditor information to be added into the to-be-verified verification function, and the verified verification function is obtained.
The auditing passing time refers to the time when an auditing party audits and passes the inquiry function to be audited.
In the embodiment, after confirming that the verification of the to-be-verified and inquired letter passes, the terminal of the auditor adds a corresponding time stamp and a corresponding digital signature for the to-be-verified and inquired letter based on the verification passing time and the digital signature, and further obtains the checked and inquired letter.
Obviously, in the embodiment, the private key of the auditing party is adopted to encrypt the to-be-audited inquiry certificate, so as to obtain the digital signature of the auditing party, and the corresponding time stamp and the digital signature are added for the to-be-audited inquiry certificate to pass the auditing, so that the checked inquiry certificate is obtained. The digital signature of the auditor is added to the checked and verified certificate and the corresponding time stamp is passed, so that the security and the non-tamper property of the checked and verified certificate are ensured.
Based on the above embodiment, as shown in fig. 4, this embodiment provides an alternative implementation manner for obtaining the check text, which specifically includes the following steps:
s401, searching a public key of the auditing requirement party from the blockchain network.
The public key of the auditing requirement party corresponds to the private key of the auditing party, and is used for decrypting the data encrypted by the private key of the auditing party.
Alternatively, the public key of the auditing demander may be queried from the blockchain network. Specifically, the auditing requirement party can broadcast its own public key to the blockchain in advance for uplink storage. Optionally, an association storage relationship between the identification information of the auditing requirement party and the public key of the auditing requirement party may be pre-established, and the association storage relationship between the identification information of the auditing requirement party and the public key of the auditing requirement party is broadcasted to the blockchain for uplink storage, where the identification information of the auditing requirement party may be the number, the ID, etc. of the auditing requirement party, and the identification information of the auditing requirement party and the public key of the auditing requirement party are in one-to-one correspondence in the association storage relationship.
In this embodiment, since the terminal of the auditing party belongs to the blockchain node, the terminal of the auditing party may query the public key of the auditing party corresponding to the identification information of the auditing party from the blockchain network based on the relationship between the identification information of the auditing party and the public key of the auditing party.
S402, encrypting the checked check-up letter based on the public key of the checking-up demand party to obtain a check-up letter ciphertext.
Optionally, after the terminal of the auditing party obtains the public key of the auditing party, the public key of the auditing party can encrypt the verified and inquired letter, thereby obtaining the inquired letter ciphertext corresponding to the verified and inquired letter.
In this embodiment, a public key of the auditing requirement party is obtained, and the authenticated inquiry function is encrypted based on the public key of the auditing requirement party, so as to obtain an inquiry function ciphertext. The public key of the auditing requirement party is used for encrypting the audited inquiry function, so that the safety of the audited inquiry function is ensured, and the subsequent auditing requirement party can conveniently decrypt the audited inquiry function from the inquiry function ciphertext based on the private key of the follow-up auditing requirement party.
On the basis of the embodiment, after the related uplink storage of the query ciphertext and the to-be-checked query, the method further comprises: and adjusting the state information of the to-be-checked evidence inquiry function to pass verification so that the checking requirement party can send an inquiry function inquiry request to the checking party by taking the to-be-checked evidence inquiry function as the to-be-checked evidence inquiry function after detecting that the state information of the to-be-checked evidence inquiry function passes verification.
The state information of the check-up letter refers to the check state of the check-up letter, and optionally, the state information of the check-up letter comprises the state of the check-up letter received, the state of failed verification and the state of passed verification. The inquiry function to be inquired refers to a request for inquiring the inquiry function to be inquired, which is sent to a terminal of an auditor when the auditor has the requirement for inquiring the inquiry function to be inquired. The inquiry request of the inquiry function refers to a request for inquiring the inquiry function to be inquired, which is sent by an auditing party in the direction of auditing the demand, wherein the request can comprise the inquiry function to be inquired or the identification of the inquiry function to be inquired. The to-be-queried query function can be a to-be-checked query function, and the to-be-queried query function identifier can be a to-be-checked query function identifier.
In this embodiment, after the query ciphertext and the query to be checked are stored in a linked manner, the terminal of the auditor changes the state information of the query to be checked into a verification passing state, so that after the subsequent audit requirement party determines that the state information of the query to be checked is the verification passing state, the audit requirement party can use the query to be checked as the query to be queried (i.e. the query to be queried), and sends a request for querying the query to the auditor.
Obviously, in the embodiment, after the terminal of the auditing party changes the state information of the to-be-audited inquiry function into the verification passing state, the auditing party can send a request for inquiring the to-be-inquired inquiry function to the auditing party without waiting for manually mailing the audited inquiry function, so that the labor cost and auditing time can be reduced, and the auditing efficiency is improved.
On the basis of carrying out associated uplink storage on the ciphertext of the query and the query to be checked, the embodiment provides an alternative implementation mode for obtaining the checked query corresponding to the query to be checked, and specifically as shown in fig. 5, the method comprises the following steps:
s501, responding to a query request of the query function sent by the auditing requirement party, and determining the query function to be queried.
The inquiry function to be inquired can be the same as or different from the inquiry function to be checked.
In this embodiment, after detecting that the state information of the to-be-checked and verified letters is a verified state, the checking requiring party uses the to-be-checked and verified letters as the letters to be queried (i.e. the to-be-queried letters to be queried), sends a request for querying the to-be-queried letters to the checking party, and the terminal of the checking party receives the request for querying the to-be-queried letters sent by the checking requiring party, and determines the to-be-queried letters to be queried based on the query request of the letters to be queried. Optionally, if the query request includes the query to be performed (i.e., the query to be checked), the query to be performed (i.e., the query to be checked) may be directly obtained from the query request.
S502, searching a query function ciphertext corresponding to the query function to be queried from the blockchain network.
Optionally, the to-be-checked query function is taken as the to-be-checked query function, and the association relationship between the query function ciphertext and the to-be-checked query function is established before the terminal of the auditor, so that the query function ciphertext corresponding to the to-be-checked query function (i.e. the to-be-checked query function) can be determined according to the association relationship and the to-be-checked query function.
Or, because the terminal of the auditor has previously established the association between the query ciphertext and the identification of the query to be audited, the query ciphertext corresponding to the identification of the query to be audited can be determined based on the association between the query ciphertext established before the terminal of the auditor and the identification of the query to be audited.
And S503, feeding back the query cipher text corresponding to the query to the auditing requirement party for the auditing requirement party to decrypt the checked query corresponding to the query from the query cipher text corresponding to the query to be queried based on the private key of the auditing requirement party.
