< method example >
The embodiment provides a file content auditing method which is applied to a blockchain network.
In this embodiment, the blockchain network includes a management node, at least one audit node, a plurality of check nodes, and at least one computing node. In addition, as shown in fig. 3, the blockchain network provided in this embodiment may include a management node, an audit node 1, three check nodes, for example, a check node 1, a check node 2, and a check node 3, and three calculation nodes, for example, a calculation node 1, a calculation node 2, and a calculation node 3, and of course, other numbers of audit nodes, check nodes, and calculation nodes may be included in the blockchain network in this embodiment.
Fig. 2 is a flow chart of a method for auditing contents of a file according to an embodiment of the present disclosure, as shown in fig. 2, the method may include steps S2100 to S2400 as follows:
in step S2100, the first audit node extracts content feature information of the file and broadcasts a query message when receiving the file.
The first audit node may be audit node 1 in fig. 3, i.e. the audit node 1 may be deployed at audit authority a, i.e. the audit of the file content is completed by the audit authority a.
The files are typically media files such as, but not limited to, including video files, picture files, and audio files.
The content characteristic information of the file is information indicating the content characteristics of the file.
The query message at least carries content characteristic information of the file.
In this embodiment, when the first audit node in the step S2100 receives the file, the first audit node extracts the content feature information of the file, and broadcasts the query message may further include the following steps S2110 to S2120:
step S2110, a feature extraction algorithm configured by the management node and a first broadcast address are acquired.
In this step S2110, the management node configures a feature extraction algorithm list required for the auditing node, and the auditing result queries the broadcast address (first broadcast address), and after receiving the file, the auditing node may select a required feature extraction algorithm from the feature extraction list.
Illustratively, three feature extraction algorithms exist in the feature extraction algorithm list required by the management node to configure the auditing node 1, and the auditing node 1 may select one feature extraction algorithm from the three feature extraction algorithms for extracting content feature information of the file.
In step S2120, content feature information of the file is extracted based on the feature extraction algorithm.
In step S2130, the query message is broadcast via the first broadcast address.
In step S2130, after obtaining the content feature information of the file, the query message carrying the content feature information can be broadcast to the blockchain network through the first broadcast address.
The query message may carry content feature information of the file, may also carry file basic information of the file, and may of course also carry other information, for example, a feature extraction algorithm for extracting content feature information of the file, and the like.
In this embodiment, before the query message is broadcast by the first broadcast address in step S2130, the first audit node further obtains the digital certificate of the first audit node configured by the management node, and uses the digital certificate to digitally identify the query message, and then broadcasts the query message.
The digital certificate is a digital certificate for marking the identity information of each party in the communication of the blockchain network, and can be used for identifying the identity of the other party on the blockchain network.
The digital certificate of the first auditing node can be configured in advance by the management node so as to utilize the digital certificate to realize the identity authentication and mutual trust of all parties.
Here, the query message may carry content feature information of the file after the digital identifier, and may also carry basic information of the file after the digital identifier, and of course, may also carry other information, for example, a feature extraction algorithm for extracting content feature information of the file after the digital identifier.
Under the condition that the first check node receives the file, extracting the content characteristic information of the file, broadcasting the query message, and entering into:
step S2200, the first computing node receives the inquiry message, matches the content characteristic information, obtains the target content characteristic information, and broadcasts the verification message.
The first computing node may be any one of a plurality of computing nodes, for example, may be the computing node 1 in fig. 3, may be the computing node 2 shown in fig. 3, or may be the computing node 3 shown in fig. 3, that is, each computing node needs to match content feature information to obtain target content feature information matched with the content feature information.
In this embodiment, the first computing node in step S2200 receives the query message, matches the content feature information to obtain the target content feature information, and broadcasts the check message may further include steps S2210 to S2240 as follows:
step S2210, a feature matching algorithm configured by the management node and a second broadcast address are acquired.
In this step S2210, the management node configures a feature matching algorithm list required for the computing node, and verifies the broadcast address (the second broadcast address), and the computing node may select a required feature matching algorithm from the feature extraction list after receiving the query message.
The first broadcast address and the second broadcast address may be the same address or different addresses.
Illustratively, three feature matching algorithms exist in the feature matching algorithm list required by the management node to configure the computing node 1, and the computing node 1 may select one feature matching algorithm from the three feature matching algorithms for calculating the similarity between the content feature information and the content feature information stored locally by the computing node 1.
Three feature matching algorithms exist in the feature matching algorithm list required by the management node to configure the computing node 2, and the computing node 2 can select one feature matching algorithm from the three feature matching algorithms to be used for calculating the similarity between the content feature information and the content feature information stored locally by the computing node 2.
Three feature matching algorithms exist in the feature matching algorithm list required by the management node to configure the computing node 3, and the computing node 3 can select one feature matching algorithm from the three feature matching algorithms to be used for calculating the similarity between the content feature information and the content feature information stored locally by the computing node 3.
It will be appreciated that the feature matching algorithms selected by computing node 1, computing node 2 and computing node 3 may be the same or different.
It will be appreciated that the content characteristic information stored locally at computing node 1, the content characteristic information stored locally at computing node 2, and the content characteristic information stored locally at the computing node may be the same or different.
Step S2220 calculates the similarity between the content feature information and the content feature information stored locally at the first computing node, based on the feature matching algorithm.
Continuing with the example of step S2210 described above, the computing node 1 may calculate the similarity of the content feature information and the content feature information stored locally by the computing node 1. The computing node 2 may calculate the similarity of the content characteristic information and the content characteristic information stored locally at the computing node 2. The computing node 3 may calculate the similarity of the content characteristic information and the content characteristic information stored locally at the computing node 3.
Step S2230 obtains target content feature information from the content feature information stored locally at the first computing node according to the descending order of ordering for each similarity.
In this step S2230, the content feature information stored locally at the first computing node having a similarity with the content feature information exceeding the preset value may be used as the target content feature information. That is, the target feature information may be obtained in one or a plurality of pieces.
Continuing with the example of step S2220 described above, the target content feature information obtained by computing node 1, computing node 2, and computing node 3 may be the same or different.
The preset value may be a value set according to an actual application scenario and an actual requirement.
In step S2240, the check message is broadcast through the second broadcast address.
And the verification message at least carries the content characteristic information and the target content characteristic information.
Continuing with the example of step S2230 above, computing node 1 may broadcast a check message via the second broadcast address, computing node 2 may broadcast a check message via the second broadcast address, and computing node 3 may broadcast a check message via the second broadcast address.
Receiving the query message at the first computing node, matching the content characteristic information to obtain target content characteristic information, broadcasting the check message, and entering:
In step S2300, the first check node receives the check message, and checks the target content feature information and the content feature information according to the set check item, to obtain a check result.
The set check item may include a check item as to whether the target content feature information and the content feature information are authentic.
In this embodiment, the first check node in step S2300 receives the check message, and checks the target content feature information and the content feature information according to the set check item, and the obtaining of the check result may further include steps S2310 to S2330 as follows:
in step S2310, the first check node performs a check item on the target content feature data and the content feature data in case of receiving the check message.
Illustratively, the check node 1 performs a check item for the target content feature information and the content feature information in the check message in case of receiving the check message, i.e. checks whether the target content feature information and the content feature information are authentic, and performs step S2330 in case of passing the check.
In step S2320, the first check node initiates a check request to other check nodes of the blockchain network to execute check items on the target content feature information and the content feature information by the other check nodes if the target content feature and the content feature pass the check items.
And the verification request at least carries the content characteristic information and the target content characteristic information.
Illustratively, the check node 1 initiates a check request in the blockchain network in case the target content feature information and the content feature information are trusted. For example, after receiving the verification request, the verification node 2 may also perform a verification term on the target content feature information and the content feature information in the verification message, that is, verify whether the target content feature information and the content feature information are authentic, and in the case of verification passing, return a verification passing message to the verification node 1.
For another example, after receiving the verification request, the verification node 3 may also execute a verification term for the target content feature information and the content feature information in the verification message, that is, verify whether the target content feature information and the content feature information are trusted, and in the case of verification passing, return a verification passing message to the verification node 1.
In step S2230, the first check node obtains the target content feature information and the check result of the content feature information passing through the check item when receiving the check passing message returned by the at least two other check nodes in response to the check request.
Illustratively, check node 1 considers a pass setting check term if it receives a check pass message returned by check node 2 and check node 3.
Receiving a check message at a first check node, checking target content characteristic information and the content characteristic information according to a set check item, and entering after a check result is obtained:
in step S2400, if the verification result indicates that the target content feature information and the content feature information pass through the verification term, the first verification node determines that the content of the file is illegal content, and stores the illegal content in the blockchain network.
The illegal contents are contents which do not meet the set requirements, namely, the illegal contents are contents which are required to be removed by the auditing mechanism, and can be also understood as contents in a blacklist listed for the auditing mechanism.
In this embodiment, after the verification node verifies the target content feature information and the content feature information, the verification node determines that the content of the file is illegal after the verification is passed, so as to ensure that the data stored in the blockchain network is trusted.
According to the method, the blockchain network comprises the auditing node, the checking node and the calculating node, after the auditing node broadcasts the query message carrying the content characteristic information of the file, the calculating node searches the target content characteristic information matched with the content characteristic information, and the checking node further checks the target content characteristic information and the content characteristic information, so that the content of the file is determined to be illegal content under the condition that the checking is passed, namely, the sharing of the illegal content information which is audited and found by all auditing nodes is realized through the intelligent distributed auditing network, the fact that all auditing nodes repeatedly audit illegal content is avoided, and the auditing cost is reduced.
In one embodiment, the first check node checks whether the content of the file meets the set requirement or not by the first check node to obtain a content checking result under the condition that the check result indicates that the target content characteristic information and the content characteristic information do not pass through the check item.
The set requirement may be a requirement to meet offending content.
For example, when the verification result indicates that the target content feature information and the content feature information do not pass the verification term, the verification node 1 notifies the verification node 1, and after receiving a notification message indicating that the target content feature information and the content feature information do not pass the verification term, the verification node 1 verifies the content of the file, so as to obtain a content verification result, where the content verification result may be that the content of the file is illegal content or that the content of the file is not one of the illegal content.
In this embodiment, after obtaining the content auditing result, the method further includes: the first audit node acquires a third broadcast address configured by the management node; and broadcasting the content auditing result by the first auditing node through the third broadcasting address.
The broadcast address (third broadcast address) is typically uploaded by the management node for the audit result required by the audit node to be configured. The third broadcast address may be the same as or different from the first broadcast address and the second broadcast address.
Next, an example document content auditing method is shown, and referring to fig. 3, the document content auditing method may include the steps of:
step S1, an audit result query module of the audit node 1 extracts content characteristic information of the file, digital identification is carried out on the content characteristic information and the file basic information by using a digital certificate of the audit node 1, and a broadcast address broadcast query message is queried through the audit result.
And S2, after the computing node 1, the computing node 2 and the computing node 3 receive the query message, carrying out matching calculation on the content characteristic information and the content characteristic information locally stored in the computing node according to a characteristic matching algorithm.
Step S3, after any one of the computing nodes 1, 2 and 3 obtains the matched target content characteristic information, a verification message is broadcast through verification broadcast addresses, and the verification message carries the content characteristic information and the target content characteristic information.
Step S4, after receiving the verification message, the verification node 1 performs local verification on the content characteristic information and the target content characteristic information.
Step S5, the check node 1 sends a check request after the check is passed.
Step S6, after receiving the verification request, the verification node 2 performs local verification on the content characteristic information and the target content characteristic information.
Step S7, the check node 2 returns a message that the check passes after the check passes.
Step S8, after receiving the verification request, the verification node 3 performs local verification on the content characteristic information and the target content characteristic information.
Step S9, the check node 3 returns a check passing message when checking passing, and the check node 1 writes the verification result into the blockchain network when receiving the check passing messages returned by the check node 2 and the check node 3.
And step S10, the check node 1 informs the audit result inquiry module that the content of the file is illegal through the blockchain network, and the audit result inquiry is completed once.
