With the problem that is difficult to find and analyze the target objects due to no sufficient recorded information and loose relativity among records in traditional audit-log model of databases, the changed information of object value are added into the audit log, and a session-tree is used to indicate the relations between operations and sessions. The improved model can improve the efficiency and accuracy for ascertaining the liabilities, and efficiently detect the roles conflict latently or security events in large time-span.
