Also it can return to whether audit log is successfully stored the response message on block chain to log audit server 11.Log audit
After server 11 receives the response message, for the audit log that success stores, the corresponding audit log in log library 110
Cochain pass flag is made at entry.In other embodiments, it can also be not provided with log library 110, but only by audit log
It is stored on the block chain of the creation of block chain network 121.
Audit user 13 be audit movement user and the client of log audit server 11.Audit user
13 points are two classes：Administrator and ordinary user, administrator are the administrators of auditing system, he can also audit all applications examine
Count log.The groundwork of administrator have creation access log audit server 11 application (for application create access key with
Secret), the permission of the audit log of distributing user access application creates and safeguards that necessary audit action lists are (such as fixed
Adopted series of standards movement：Creation, access, update, deletion etc.).And common log audit user may only check administrator
The audit log of the application of distribution.
When the user 13 that audits audits to audit log, user 13 is audited first from log audit server 11
Inquiry log list in log library 110 can pass through the filter conditions such as inputting date, keyword, Apply Names, action behavior
To position specific log.If the entry of the audit log of inquiry has cochain pass flag, illustrate the audit of the entry

Analysis, it can be determined that whether user has permission to access audit log to be checked.After determining that user has permission, just carry out down
The step 205 in face.
Step S205 is corresponding with step S202 and an optional step.After receiving the second request of user,
In step S205, audit log to be checked is read from log library based on characteristic information.For example, according to keyword, the date,
The characteristic informations such as Apply Names, action behavior position specific log recording in log library.
In step S206, audit log to be checked is also read from block chain based on characteristic information.Specifically,
The standard interface that audit log intelligence contract is called based on the relevant characteristic information of audit log, from audit log intelligence
The audit log is inquired in block chain where contract.
In addition, this method can also comprise the steps of although being not shown in Fig. 2：
After receiving audit log in step s 201, to the signature in audit log (as described referring to Fig.1 above
, signed by application) it is verified.In this way, determining that the audit log is true log recording.Also, to signature
Verification pass through in the case where, just carry out step S202 and step S203.
In addition, can also receive indicates whether audit log is successfully stored in block chain after step S203
Response message.If the response message instruction audit log received is successfully stored in block chain, right in log library
Corresponding Audit Journal entries make cochain pass flag.
