WebSense Patents Censorware System

Matthew Skala writes "As reported in SiliconValley.internet.com, filtering-software vendor Websense has received US Patent 6,606,659 on a "System and method for controlling access to internet sites". The new features in the patented system seem to revolve around using time limits instead of filtering sites out entirely; offering users a choice of viewing a site and having it logged, or not viewing it; and a scheme for automatically categorizing sites that looks very much like the "Bayesian filters" we've heard so much about in recent weeks. You may be interested in the filtering company's press release about their patent, or my own view."
