After logging in the database, the first party and the second party acquire the transaction order stored in the database, and then locate the corresponding privacy data of the transaction data in the transaction order, wherein the privacy data is the information of the settlement person and the settlement time of the settlement parties, and the privacy data is set to be in an inaccessible state.
6. The blockchain-based settlement data processing method of claim 5, wherein the process of acquiring the transaction data and defining transaction feedback information, and analyzing the transaction feedback information to determine whether to reach the current transaction comprises:
when the transaction order is generated, the transaction order corresponding settlement funds are paid to a set third party, the third party is used for storing the settlement funds instead, the two settlement parties are associated with corresponding mobile equipment ends, an identity verification form is built in the mobile equipment ends, the identity verification form records the allowed IDs of equipment login verification of the two settlement parties, the equipment login IDs of the two settlement parties are obtained, whether the equipment login IDs are consistent with the allowed IDs or not is judged, if yes, the mobile equipment ends are logged in, the database is logged in through the mobile equipment ends, transaction data are obtained, and if not, the mobile equipment ends are forbidden to log in;
After the transaction data are obtained by the settlement parties, judging whether the transaction data conform to expected transaction data formulated in advance by the settlement parties, and defining transaction feedback information corresponding to the settlement parties according to a judging result, wherein the transaction feedback information comprises 'conform to expectation, allow a third party to carry out settlement fund transaction payment' and 'not conform to expectation, prohibit the third party from carrying out settlement fund transaction payment';
And sending the transaction feedback information to a third party, and when the third party receives that the transaction feedback information sent by both settlement parties is ' in accordance with expectations ' and the third party is allowed to carry out settlement fund transaction payment ', carrying out the transaction payment of settlement fund so as to achieve the transaction, otherwise, prohibiting the transaction.
7. A blockchain-based settlement data processing system for implementing the settlement data processing method according to any one of claims 1 to 6, characterized by comprising the following modules:
The settlement preparation module is used for acquiring settlement data of both parties of settlement, storing the settlement data into the blockchain, distributing transaction blockchains by the blockchain, and defining corresponding settlement logic for the transaction blockchains;
The verification processing module is used for verifying the settlement data of both settlement parties after the transaction block chain acquires the settlement logic, generating transaction data according to the settlement data after the verification is passed, carrying out cooperative interaction processing on the transaction data, and submitting the transaction data to a preset database for storage;
the settlement determining module is used for setting the login permission of the database, performing privacy protection operation on the database, logging in the database through the mobile equipment terminals of the settlement parties to acquire transaction data and define transaction feedback information, and analyzing the transaction feedback information to determine whether the transaction is completed.
