OEIPL, developers of the popular content filtering software – SafeSquid, recently released a new version of SafeSquid Business Edition for Windows. The highlight of this release is its capability to block pornographic images from almost any source in real-time. Image Filter does not take into consideration the source of the image, not the application used to view it. It could be a web page accessed from a browser, or an email accessed from a web-mail application.
SafeSquid forwards all images that are being accessed through it, to the Pornographic Image Filter module, which then analyzes the graphic content of images, like skin tones, contours, etc. and allocates a score to the images. The score ranges from -10.00 to +10.00. An image is very likely to be pornographic if it scores higher, and less likely if it scores lower. SafeSquid administrators can define a threshold score, and the images that score higher than the threshold score are then blocked by SafeSquid. Depending on user profiles, administrators can even define a different threshold limit for different users or groups of users.
Although Pornographic Image Filter is about 90% accurate, with about 10% false positives and negatives, it acts as a good deterrent. Image Filter could be very useful, especially in education institutes. With image filter in place, administrators could make sure that even if users manage to bypass filters like Keyword Filter, URL Filter and URL Blacklist, they would still not be able to view unwanted images. Such images will get blocked even when they are served from hosts that would usually allowed access to.
