<p>A processor has a recording medium, an extraction section, and a judgment section. The recording medium contains storage information including suspicious person image data for identifying a suspicious person. The extraction section extracts image data on the face part of the user from the image data of a security camera as extracted image data only when the result of the authentication of an authentication device shows a "failure." The judgment section judges whether or not the user is a suspicious person by searching whether or not specific image data which is identified to be identical to the extracted image data is present as the suspicious person image data in the storage information. Furthermore, the judgment section records the extracted image data as the suspicious person image data on the recording medium when the presence of the specific image data is denied. When the judgment section judges the user to be a suspicious person, an alarm device issues a warning.</p> |
