What does URLChecker do?
Conventional URL blocking software relies on a list of URLs to block access. This list needs to be constantly updated to ensure that new sites containing pornographic material are blocked. The problems with keeping the list up-to-date are locating new websites and ii) checking whether they are pornographic or not. The first problem is handled by storing all URLs being accessed from within the community being protected. The majority of URLs accessed will not be new and are easily identified through comparison with the list of previously accessed URLs. The second problem is solved by URLChecker which automatically classifies URLs as being pornographic or not. URLChecker improves productivity in maintaining lists of pornographic URLs by over 1,000%.
