Overview
One of the most common issues with e-mail today is that even with most stringent e-mail policies in place, it is very difficult to effectively control the content of image and movie attachments: most messages with silly jokes, offensive or pornographic attachments do not include any keywords in the message body that would allow easy identification by keyword scan. Surely, the network administrator can quarantine all movie clips and review their content on a regular basis before allowing them through. But it is a considerably time consuming and manual process that only partially solves the problem.


What about JPEG and GIF and other image attachments? With so many legitimate messages today containing company logos, signatures or other legitimate business graphics, control of visual e-mail content proves to be an unwelcome chore for many IT managers.


Omniquad ImageTrap, a complete e-mail visual content management system will address all these issues and save yourself a great deal of time. This server-based plug-in is integrated into Omniquad Mailwall e-mail content security framework and is compatible with most mail
servers; it looks for image and movie attachments in inbound/outbound mail and intercepts them, allowing messages through or stops them depending on the content of attached images / movie clips.


ImageTrap classifies image/movie attachments into:

- neutral content (company logos, technical drawings, family photos, landscapes
etc)
- jokes (anything that makes you laugh but is unlikely to cause offence)
- offensive/shocking (pictures sent to shock, provoke or offend the viewer for example
images depicting women in derogatory manner etc. )
- partial nudity (partially exposed body parts, bikinis etc)
- pornography

A unique fingerprint is generated for each image/movie clip and the master Image Bank is queried to get the content classification for the attachment itself. If the image content is not known, a thumbnail is uploaded to the Image Bank server for categorisation where an automated intelligent process links it with a similar series already classified or a human researcher in the operations centre will enter correct classification. Only thumbnails are sent without any sender/recipient information. Once your local ImageTrap gets assigned a category for an image, it is stored in a local cache and does not query the ImageBank again when the same image is intercepted the next time.
