Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Example 1:
the embodiment provides a data auditing method for a blockchain.
Referring to fig. 1, it is shown that the method includes step S100, step S200, step S300 and step S400.
S100, obtaining audit task information, wherein the audit task information comprises a service identifier of a target audit service and a node identifier corresponding to the service identifier. The audit task information may be generated automatically by the current node after the current service department reports the information of the target audit service to the current node, or may be obtained directly by the current node, for example, an auditor issues the audit task information corresponding to the target audit service to the current node. The audit task information is used for indicating the current node to start the audit task, one audit task is corresponding to audit business of a project mark, and each project mark audit business has a unique corresponding business identifier. The project mark auditing service is not only related to the current service department, but also related to other service departments, and the node identification which is carried by the auditing task information and is related to the target auditing service comprises but is not limited to the node identification of the current node.
It is understood that step S100 is preceded by steps S90, S91, S92 and S93, wherein:
s90, responding to a request message indicating auditing of the target auditing service, wherein the request message comprises a service identifier of the target auditing service and a corresponding node identifier;
s91, acquiring an audit business model of a business department corresponding to the current node, wherein the audit business model comprises a business identifier and business description information of a business to be audited;
it should be noted that S91 includes S910, S911, S912, and S913 thereafter, where:
s910, obtaining audit data corresponding to the audit service model according to the audit service model; after the service department reports the related information, the current node is triggered to audit the corresponding service, so that the problem that an auditor cannot know the suspicious audit service is solved, and the audit cost for finding the suspicious audit service through data analysis is saved.
S911, creating an intelligent contract according to a bilinear arithmetic algorithm, wherein the intelligent contract comprises a data calling interface;
s912, calling an intelligent contract under the condition of running an audit service model;
s913, calculating the audit service model through the data call interface to obtain service operation data of the current node.
S92, acquiring service operation data corresponding to the service identification from the current node, and matching the audit service model with the service operation data;
and S93, generating audit task information according to the obtained matching result.
S200, acquiring service data of the service identifier corresponding to the node identifier according to the at least one node identifier.
It can be understood that, in this step, assuming that the node identifier carried in the audit task information is only the node identifier of the current node, the current node searches and acquires the service data associated with the service identifier from the local built-in database, and searches and acquires the service operation data associated with the service identifier from the federation block chain. The service operation data is stored in the federation block chain according to the uplink rule, and the service operation data is data used for operating the service data, for example, SQL including any one or a combination of more than one of add, delete and change instructions.
S300, acquiring first information, wherein the first information comprises business operation data corresponding to the business identification acquired from the block chain cluster.
It is understood that step S300 is preceded by steps S290, S291, S292, and S293, wherein:
s290, storing the service data into a specified file system; user behavior data is generated when a database client uses a database server. The user behavior data includes, but is not limited to, data obtained by monitoring at least one operation of login, access, read-write, deletion, modification and the like of the database server by the database client. The audit server can use all the operation data of login, access, read-write, deletion and modification as the audit information, and can use only the abnormal operation data as the audit information. For example, data which does not change the operation of data content, such as login, access, read data, etc., is not used as audit information; and data, such as write data, delete data, modify data, update data, and the like, which relate to an operation of changing the contents of the database, is used as audit information.
S291, calculating to obtain abstract information of the service data according to a Hash algorithm;
s292, storing the summary information and the file information related to the summary information into the block chain cluster according to a block chain storage rule; after the audit information is obtained from the audit server, hash operation can be carried out on the audit information, and the obtained hash value is sent to the block chain cluster for storage. After the block chain receives the hash value of the audit information, the received hash value can be stored in a certain block of the block chain firstly and then issued to the whole network.
S293, judge whether the block in the block chain cluster is full, if not, store the hash value and file information of the business data in the Mercker tree of the new block.
If the storage space of the new block is not full, the hash value of the received audit information may be saved in a leaf node of the Mercker tree of the new block. Characteristics of the mercker tree include: the leaf node N1 stores summary information of the original data such as the above-mentioned audit information; calculating and storing the hash value of the data block of the leaf node by the child node at the upper layer of the leaf node N1; and the upper-layer child node calculates and stores the hash value of the data of the lower-layer child node connected with the upper-layer child node, and the root node calculates and stores the hash value of the data of the child node connected with the root node. According to the characteristics of the Mercker tree, when the hash value of new audit information is added to the leaf node of the Mercker tree of a new block every time, the hash values stored in all levels of child nodes and root nodes related to the newly added leaf node in the Mercker tree are recalculated.
It should be noted that S300 includes S301, S302, S303, S304, S305, and S306, where:
s301, obtaining a hash value of audit task information;
s302, sending the hash value to a block chain and storing the hash value on the latest block of the block chain;
s303, taking the hash value on the latest block as a main key, acquiring a storage address of the hash value on a block chain, and taking the storage address as an initial value;
s304, calculating and generating a key value pair corresponding to the audit task information according to the storage address;
s305, receiving second information, wherein the second information comprises a data query request sent by a data verification end, and the query request is queried according to service operation data corresponding to a service identifier in audit task information;
s306, judging whether the hash value in the query request can be matched with the key value pair or not according to the second information.
Specifically, for example, when a user requests to delete some entries in the database, behavior data corresponding to user deletion operations, such as a user name of the user, a location of the deleted entry, and a deletion number, may be recorded. The behavior data corresponding to each user deletion operation can be used as audit information, and the behavior data corresponding to the abnormal deletion operation can also be used as audit information when abnormal deletion is monitored. For example, if the number of items deleted by a certain username at one time is large, such as more than 1000, the username, the deleted location, the deleted number, and the like may be recorded.
After generating audit log and other audit information, the audit server can generate an audit report according to the audit log. The block chain is a distributed database which is decentralized and distrusted, and recorded information can be effectively prevented from being tampered by a consensus mechanism and an encryption algorithm. And can be traced back to any time. Database audit information may also be stored in other specified file systems. Such as a local distributed file system or a cloud distributed file system. And then, storing the summary information of the database audit information and the file information of the database audit information stored in the specified file system into the block chain cluster. The file information may include ID of the database audit information in the specified file system, timestamp, file size, etc. And the file system can find the storage position of the database audit information according to the ID. The summary information and the file information of the database audit information are stored in the block chain cluster, so that the database audit information (such as user login, database access and operation information) can be guaranteed to be incapable of being tampered once being recorded, and traceability is achieved. Therefore, the summary information of the audit information is stored in the block chain cluster, and the subsequently generated audit report is more real and reliable.
The audit task information end can actively acquire or passively receive original data, hash processing is carried out on the audit task information by the audit task information end through a hash algorithm to obtain a hash value, wherein the hash algorithm can be one or a combination of algorithms such as MD5, SHA-1 and SHA 256.
In practical application, the sensor, the industrial personal computer and the like can transmit the original data in the JSON format, the character string format or the binary array format to the original data terminal through communication modes such as wired, wifi, ZigBee and the like.
And then, sending the hash value to a block chain network, after receiving the hash value aiming at the original data sent by the second information, the block chain network newly generates a latest block on the block chain after the consensus authentication of each block node in the block chain, storing the hash value on the latest block of the block chain, enabling a data auditing end to generate a key value pair corresponding to the hash value of the original data, and auditing whether the target data corresponding to the original data is consistent with the original data according to the key value pair. The blockchain may be a public chain, a private chain, or a federation chain.
Further, after receiving the hash value of the original data, the block chain may compare all hash values stored in the block chain, and generate a latest block on the block chain if the hash values identical to the hash value of the original data are not compared. When the hash value identical to the hash value of the original data is compared, the hash value identical to the hash value of the original data is used as a value, and the address of the block storing the hash value identical to the hash value of the original data is used as a main key.
S400, generating operation information of the target audit service according to the service data and the service operation data, and auditing the target audit service according to the operation information. According to the service data and the service operation data, an activity path of the service data flowing from the starting end to the tail end can be presented to restore the historical activity track of the target audit service, and the historical operation information of the target audit service is obtained.
It is understood that step S400 is followed by steps S401, S402 and S403, wherein:
s401, determining that the service to be audited is an abnormal auditing service;
s402, extracting missing data in the abnormal audit service, and sending a message for indicating to submit the missing data to a service department corresponding to the current node;
s403, judging whether the business department corresponding to the current node submits the missing data determined according to the matching result, if not, requiring the business department to reinitiate a request for submitting the missing data.
For example, when the audit service model and the service operation data are not matched, it can be directly determined that the service to be audited is the suspicious audit service. In order to solve the problem, when a business operation data record which cannot be matched with any submitted audit business model appears during specific implementation, an urging alarm message is generated to prompt an audited business department to submit the missing data. By the arrangement, data loss caused by network transmission problems or human errors can be avoided, and the opportunity of resubmitting the audit service model is given to a service department.
