Referring to fig. 4, the service information specifically includes department information and transaction information. Referring to fig. 5, the certificate selected by the user node specifically includes an identity card and a driving license.
And step three, selecting corresponding certificates and confirming submission by the user node based on the selection of the user.
And the user selects the certificate to be submitted according to the service information, clicks a confirmation submission button, and submits the corresponding certificate to the office node through the user node.
And step four, the office node determines the certificate selected by the user node.
After the user node submits the certificate, the transaction department determines that the certificate selected by the user is correct and handles the corresponding matters.
The transaction department node prompts the certificate required by the transaction material to the user through the transaction item information in the service information, so that a plurality of certificates can be submitted at one time, the probability of selecting wrong certificates by the user is reduced, and the working efficiency of service transaction is improved.
In the embodiment of the application, different office department nodes have reading authorities for different certificates, and when a user node selects a certificate which does not belong to the authority range of the office department, the office department node has no authority to read the certificate which exceeds the authority range. Therefore, firstly, the office nodes need to determine the intelligent contracts pre-deployed on the blockchain platform; and determining the reading authority of the office node on the license information submitted by the user node according to the pre-deployed intelligent contract, and judging that the user node submits an error certificate when the office node has no reading authority on the license information submitted by the user node, so that the office node sends prompt information for reselecting the certificate to the user node. According to the embodiment of the application, the reading permission of different workers for the license information is set, so that the user can be reminded in time when the user selects wrong license information, the efficiency of handling the service is improved, and the risk that other license information of the user is leaked is avoided.
In the embodiment of the application, after the office node sends the service information to the user node based on the license authorization code, in order to improve the security of the service handling process, the identity of a service handling person can be identified. Then, the office node sends an authentication request to the user node according to a preset identification mode to determine the identity of the user. The preset identification mode comprises face identification, fingerprint identification and voice identification.
In the embodiment of the application, after the user identity authentication is successful, the user node selects necessary materials for transacting the business by default according to the business item information, and the user selects more electronic certificates according to the requirements of other materials required by transacting the item information and clicks to submit the electronic certificates.
In the embodiment of the application, in order to improve the safety of the business handling process, the business handling department nodes set different identification modes aiming at different levels of the license. Therefore, the office node first needs to determine the security level of the required certificate in the transaction information according to the preset level correspondence table, and then selects a corresponding identification mode to verify the identity of the user according to the security level of the certificate, so as to ensure that the transactor is the user himself. Wherein, the level correspondence table specifies different security levels corresponding to different certificates.
According to the embodiment of the application, different user identification modes are set for the security levels of different certificates, so that the protection degree of important certificates can be greatly improved.
S103: and receiving a first password generated by the user node based on the service information.
After the user node submits the corresponding certificate, a corresponding password group is generated according to the service information, the password group comprises a first password and a second password, the first password in the password group is sent to the office department node, the second password in the password group is sent to the preset certificate base by the user node, and then the office department node receives the first password generated and sent by the user node according to the service information and is used for obtaining the certificate information from the preset certificate base.
Wherein the first password and the second password of the password group correspond to each other. The password group can be preset with valid time, and the password group beyond the preset time is invalid. Therefore, the office node needs to pair the first password and the second password within the valid time, otherwise, the password group is invalid, so that the first password and the second password cannot be mutually verified. The effective time can be specifically set according to needs, and the application does not limit the effective time. The embodiment of the application further strengthens the safety of the license information transmission process by generating the two encrypted passwords.
S104: and matching the first password with a second password of a preset license library, and calling corresponding user license information in the preset license library according to a matching result.
S105: and writing the certificate information and the service information into the block chain platform in a correlation manner.
And the office department node pairs the first password of the office department node with the second password of the preset license library, and calls the user license information corresponding to the service information in the preset license library according to the successful pairing result. The preset certificate library is used for storing various certificate information of the user.
And finally, associating the license information with the service information by the office door node, and writing the license information into the block chain platform.
In the embodiment of the application, the office department node sends a first password of the office department node to a verification interface of a preset license library, the authentication interface is paired with a second password received by the preset license library, and if the pairing is successful, the request for calling the user license information is accepted after the first password and the second password are proved to be correct password groups; and if the pairing fails, the first password and the second password are proved to be wrong password groups, or the password groups are failed, and a prompt message of the pairing failure is returned.
Important information in a certificate may change greatly over time, so that the certificate is generally provided with a validity period. When the service is transacted, the certificate exceeds the validity period, so that the service transaction fails.
In the embodiment of the application, after the corresponding user license information in the preset license library is called by the office department node, the residual validity period of the user license information is determined according to the user license information, and when the residual validity period of the user license information is lower than the preset value, a prompt that the license is about to fail is returned to the user node.
The preset value can be specifically set according to needs, and the preset value is not limited in the application. According to the embodiment of the application, the residual validity period of the user license information is determined through the user license information, so that the user can be timely reminded when the license information is about to fail, the situation that the service is transacted due to the fact that the user forgets the residual validity period of the license information and cannot transact the service according to the failed license information is avoided, and the service efficiency is reduced.
In the embodiment of the application, the staff corresponding to the business handled by the user can be conveniently searched, and meanwhile, the error in the business handling process can be tracked. Therefore, the office department node associates the license information of the user with the corresponding service information and writes the license information into the block chain platform.
