Specifically, when judging the account After checking whether the request is an account first information request (ie, step S101 ), steps S201 to S203 are further included.

In step S201, if it is not the account first request information, continue to judge whether the account inquiry request is the account second information request, if it is the account second information request, execute step S202, otherwise end the process.

In step S202, verify whether the account public key, account first private key, account second private key and signature information in the user account query request are respectively the account public key, The first private key of the account, the second private key of the account, and the signature information are all consistent. If they are consistent, step S203 is performed. Otherwise, the process is ended and feedback is sent to the user for re-verification.

Wherein, the second account information includes basic user information of the pension account, basic pension information, account amount and account transaction information. Further, in addition to all the information contained in the first account information, the second account information also includes account amount, monthly account details and other information related to amount transactions.

In step S203, the second account information is provided to the user, and the process ends.

After the above verification is completed in this embodiment, it means that the user who initiates the account inquiry request has the authority to inquire about the second account information, and the blockchain can provide the first account information to the user who initiates the account inquiry request.

Further, after providing the user with the second account information (ie, step S202), the following steps are also included:

modifying the account's second private key; and,

Broadcast the modified account second private key in the blockchain.

In this embodiment, since the second account information involves private information such as amount transactions, in order to improve the verification security of the second account information, this embodiment changes the second private key of the account in real time. After each query, the block The smart contract platform of the chain modifies the second private key and broadcasts it in the blockchain. Specifically, the second private key is modified based on the current timestamp and the hash value of the current data block. It can be understood that the data block A data block for storing pension accounts.
