摘要
The present invention provides an injustice detecting system enabling detection of an injustice that is performed through an operation that cannot be distinguished from normal operation. This injustice detecting system is provided with: a history recording unit for recording operation history information of a monitored device; an audit information disclosure unit for disclosing audit information including at least information indicating that an audit for detecting an injustice is to be implemented; and an injustice detecting unit for detecting the injustice on the basis of pre-disclosure operation history information which is operation history information generated before the audit information is disclosed, and post-disclosure operation history information, which is operation history information generated after the audit information is disclosed.
