step 203: determining private data sets of vehicle purchase tax service corresponding to the identification from the private data sets corresponding to the preset multiple services;
step 204: determining a designated service side node corresponding to the vehicle purchase tax authorization data based on the determined private data set of the vehicle purchase tax service;
step 205: and storing the vehicle purchase tax authorization data into a database corresponding to the designated service party node so that the designated service party node can acquire the vehicle purchase tax authorization data.
Therefore, the service authority nodes in the block chain store the stored vehicle tax authorization data to the database of the appointed service party node, so that the fact that only the appointed service party node can acquire the vehicle tax authorization data from the database is realized, other nodes cannot acquire the vehicle tax authorization data, and therefore the safety of user privacy data is ensured.
In order to enable other nodes to synchronize the transaction and ensure the security of the vehicle purchase tax authorization data, after step 205 is performed, in one embodiment, the vehicle purchase tax authorization data is encrypted to obtain encrypted vehicle purchase tax authorization data; and storing the encrypted vehicle purchase tax authorization data into a public account book of the blockchain, so that other nodes except the appointed business party in the blockchain can acquire the encrypted vehicle purchase tax authorization data.
And processing the vehicle purchase tax authorization data by utilizing a hash function to obtain the encrypted vehicle purchase tax authorization data.
Therefore, the encrypted vehicle purchase tax authorization data is stored in the public account book of the blockchain, so that other nodes can synchronize the transaction, and the safety of the vehicle purchase tax authorization data is further ensured.
In one embodiment, step 205 may be implemented as: and if the vehicle purchase tax authorization data is determined not to be the designated service side node, the vehicle purchase tax authorization data is stored in a database corresponding to the designated service side node.
For example, if the node 1 determines that the self node is a designated service party node, the vehicle purchase tax authorization data is stored in a database of the self node, and if the node 1 determines that the self node is not the designated service party node, the vehicle purchase tax authorization data is stored in the database corresponding to the designated service party node. Therefore, the vehicle purchase tax authorization data can be stored in a corresponding database.
In order to save storage space, in one embodiment, a data deletion request from a service initiator node in a blockchain is received, wherein the data deletion request comprises a target vehicle purchase tax authorization data identifier and a private data set identifier; determining a private data set corresponding to the private data set identifier from a plurality of preset private data sets; and deleting the target vehicle purchase tax authorization data from the determined private data set based on the target vehicle purchase tax authorization data identifier.
For example, the private data set 1 is determined according to the private data set identifier in the data deletion request. The private data set 1 comprises vehicle purchase tax authorization data 1, vehicle purchase tax authorization data 2, vehicle purchase tax authorization data 3 and vehicle purchase tax authorization data 4. And if the data to be deleted is determined to be the vehicle purchase tax authorized data 3 according to the target data identifier of the data deleting request, deleting the vehicle purchase tax authorized data 3 from the private data set 1. Therefore, the storage space is saved, and the security of the private data is further ensured.
For further understanding of the technical solution of the present disclosure, the following detailed description with reference to fig. 3 may include the following steps:
step 301: receiving vehicle purchase tax service application information sent by a service initiator node in a block chain, wherein the vehicle purchase tax service application information comprises vehicle purchase tax service and node information of the service initiator node;
step 302: determining vehicle purchase tax authorization data corresponding to the node information from stored vehicle purchase tax authorization data according to the node information of the service initiator node; and determining the identification of the private data set corresponding to the vehicle tax purchase service;
step 303: determining private data sets of vehicle purchase tax service corresponding to the identification from the private data sets corresponding to the preset multiple services;
step 304: determining a designated service side node corresponding to the vehicle purchase tax authorization data based on the determined private data set of the vehicle purchase tax service;
step 305: storing the vehicle purchase tax authorization data into a database corresponding to the designated service party node so that the designated service party node can acquire the vehicle purchase tax authorization data;
step 306: encrypting the vehicle purchase tax authorization data to obtain encrypted vehicle purchase tax authorization data;
step 307: and storing the encrypted vehicle purchase tax authorization data into a public account book of the blockchain, so that other nodes except the appointed business party in the blockchain can acquire the encrypted vehicle purchase tax authorization data.
