There is provided a combination of software components forming a dynamic, "smart" system for limiting access to inappropriate content available in a public computer or communications network such as the WWW. An access control mechanism having a variable sensitivity is originally set to a nominal sensitivity but may relax if the user does not attempt to access inappropriate material. If, however, a user attempts to access inappropriate material, the sensitivity of the filter is adjusted to a more restrictive sensitivity. Attempts to access inappropriate material are recorded and a temporal map is formed. Statistical analysis is performed, based on the temporal map, to predict future patterns of access attempts by a user. The sensitivity of the access control mechanism is raised and relaxed based upon a user's pattern of attempts to access inappropriate material.
