The document access authorization violation detection apparatus detects, for each of documents, whether or not there is any violation in access authorization to access the document, by using statistical values calculated from duty position levels, which represents height levels of corresponding official positions of users who are authorized to access the document, or inter-organization distances, which are obtained by digitizing inter-organization positional removes from respective groups, to which the users belong, to a group whose member number is larger than any other one of the groups. As a result, the document access authorization violation detection apparatus makes it possible to efficiently detect whether or not there is any violation in access authorization with respect to each of documents. |
