The block chain-based data processing system 20 is described in detail as follows:
(1) the data acquisition module 201: the data acquiring module 201 is used for acquiring target data.
This part is the same as the above-described part of the data acquisition module 101 in fig. 1, and is not described again here.
The target data may be original data, or may be metadata, and the target data may be business data, target data, or resource data, or target data, or may be other types of data, which is not limited specifically.
Specifically, the data acquisition module 101 may be divided into a data acquisition module, an original data module, and a metadata module, where the data acquisition module acquires data written by a user, where the data may be processed data, and stores corresponding original data in the original data module, and stores metadata in the original data in the metadata module.
(2) The audit rule obtaining module 202: the audit rule obtaining module 202 is configured to obtain an audit rule. The audit rule may include at least one constraint condition of data generation, multi-party control protocol, rule, and flow defined by the blockchain, which is not specifically limited.
Here, the block chain is used to realize consensus on the basis of identity authentication and tamper resistance based on cryptography, block byzantine attacks of a few nodes, and realize a definable data update mechanism through contracts, so that access control of data writing can be realized in an open environment, and responsibility, obligation and flow of each party can be defined, that is, an audit rule can be formed as required.
(3) The uplink auditing module 203: the uplink auditing module 203 is used for performing uplink auditing on the target data according to the auditing rule to obtain an auditing result; and if the audit result is that the audit is passed, obtaining first data according to the target data uplink. In addition, if the audit result is that the audit is not passed, the uplink is prohibited according to the fact that the uplink audit of the target data is determined to be failed, and further, corresponding prompt information can be generated and output according to the reason of the audit failure.
Obviously, if the target data meets the constraint of the audit rule, the target data is determined to be approved, and if the target data does not meet the constraint of the audit rule, the target data is determined to be approved.
For example, the auditing rule includes that the monthly income of the user is determined as the privacy data, and when the user is acquired for a month, the monthly income can be jointly uplink after the user identity authentication is passed, and if the user identity authentication is not passed, the uplink audit is determined to be failed, and the uplink is forbidden.
For example, the audit rule may restrict the qualification of the user for uplink on the target data, and when the user performing uplink on the target data does not satisfy the agreed conditions, it is determined that the uplink audit fails, and uplink is prohibited.
Therefore, the cochain audit is performed before the cochain, and the authenticity and credibility of the data are ensured.
(4) The demand determination module 204: the demand determination module 204 is configured to determine a current demand according to the target data.
The corresponding relation between the demand and the target data can be set by a user.
For example, the demand amount and the target data correspond to each other in such a way that the value of the demand amount is equal to a times of the data magnitude of the target data, where a is a positive number greater than 0.
For example, the corresponding relationship between the demand amount and the target data is that when the data size of the target data is greater than or equal to b, the value of the demand amount is a fixed value c, and when the data size of the target data is less than b, the value of the demand amount is a fixed value d, c is greater than d, and c and d are not limited in particular.
(5) Target data uplink module 205: the target data uplink module 205 is configured to uplink the target data to obtain the first data when the current demand is greater than a preset demand.
The preset demand can be set together with the corresponding relation between the demand and the target data, and in an actual application scene, the preset demand can be different and set as required.
(6) Target data hash uplink module 206: the target data hash uplink module 206 is configured to hash uplink the target data to obtain the first data when the current demand is less than or equal to a preset demand.
(7) The data uploading module 207: the data uploading module 207 is configured to upload the target data to a data center station to obtain second data.
It should be noted that a secure channel is provided between the data uploading module 207 and the data center station, and the data is uploaded to the data center station through the secure channel, so that the data is actually and effectively uploaded to the data center station.
(8) Audit rules chaining module 208: the audit rule uplink module 208 is configured to uplink the audit rule after obtaining the audit rule.
It should be understood that the block chain based data processing system 20 chains the audit rule through the audit rule chain module 208, which ensures the transparency and publicity of the rule, and further ensures the trueness and credibility of the data.
(9) Tamper-proof collation module 209: the tamper-proof checking module 209 checks the first data and the second data to obtain a checking result; and if the checking result is that the first data and the second data are different, determining that the first data is tampered. In addition, if the checking result is that the first data and the second data are the same, it is determined that the first data is not tampered.
Therefore, the anti-tampering checking module can check the first data on the chain with the second data of the data center station, and the authenticity and credibility of the data on the chain can be improved.
(10) The tampered object determination module 210: the tampered object determining module 210 is configured to determine the tampered object according to the monitoring data obtained by monitoring the uplink process of the target data after determining that the first data is tampered.
And determining the tampered object so that a user can conveniently make a coping strategy according to the tampered object. The tampered object may be the data processing system 20 itself based on the blockchain, and the tampered object may also be a user of malicious intrusion, which is not limited in particular.
(11) The on-chain data control module 211: the on-chain data control module 211 is configured to delete or identify the first data through the blockchain network after determining that the first data is tampered with.
Deleting or identifying the first data through a blockchain network to improve the authenticity of the data on the chain.
(12) And the monitoring module: and the monitoring module is used for carrying out whole-process monitoring on the first data obtained according to the target data chaining to obtain monitoring data.
The monitoring module monitors the uplink process of the target data to obtain the monitoring data.
