Public Library funding stalled on questions of Internet filtering software effectiveness

Public library funding may be stalled due to questions on Internet filtering software effectiveness.

A committee in the Virginia State Senate rejected by a tie vote a bill that would cut off state funds to public libraries unless they install software to block Web sites depicting subject matter defined as “obscene” under Virginia law.

Opponents of the bill, including the Virginia chapter of the ACLU, say so-called   “filtering” software programs usually fail to block all Internet   sites being targeted while they often succeed in blocking other sites that are   not sexually oriented, such as gay or safer sex-related sites aimed at preventing   the spread of AIDS.

Unlike the Law, Internet Filtering Software Can Be Updated Instantly

"[Internet software] filters also may be more effective [than COPA] because they can be applied to all forms of Internet communication, including e-mail, not just the World Wide Web." - From Computerworld.com

Best of Breed Internet Filters

What is Internet Filtering?
Web or Internet filtering services are developed to provide organizations with advanced web filtering technology to limit exposure to security risks such as viruses and adware, while increasing productivity and ensuring bandwidth for business related activities. The vast majority of current web filtering solutions rely on allow/disallow URL lists (first generation filters) or keyword tracking filters (second generation filters).  Best of breed Internet filtering solutions use third generation Active Filtering Technology.

What's At Stake?
The primary issue with URL list based filtering technologies is an inherent reactive nature in the  filtering technique. The URL list filter cannot accept any blocking action until each individual site or domain is added to the block list. New or “stealth” sites are not blocked regardless of content. The process of finding target sites is a time intensive-extensive process. Whereas, best of breed Internet filters use Active Filtering Technology that relies on a complex set of predictive modeling rules which  read and understand content in real time. These rules have learned to distinguish subtle differences in content, creating higher accuracy without tremendous ongoing overhead.

Pornography as a web content category is a prime example of the reactive weakness in URL list filtering. The pornography industry introduces thousands of new pornographic sites every day. Therefore, the rapid environmental changes overwhelm URL list based filters, creating gaps in the block lists, leaving the filter with marginally accurate filtering and easy circumvention. Moreoever, keyword filters are the antithesis to URL lists in there reliance on static meanings of words. Any use of an inappropriate word will create a block page. This creates tremendous over-blocking of legitimate information. For instance, local governments and educational institutions have been victims of this type of filtering. The solution for overcoming these issues is through implementation of third generation Active Filtering Technology.

Active Filtering is accomplished through leveraging highly advanced Artificial Intelligence to evaluate any web page request. This technology understands web page content in a fashion similar to human comprehension. A web page is analyzed by many proprietary metrics that include the size of a page, number of images, page links, and URL name and content. Once all needed information is “harvested” by the system, the information is fed in to an expert system (AI based decision generator), which then uses precompiled rules (knowledge base) to identify the web page type and whether a web user can/cannot view the requested web page. As a result, this filtering mechanism achieves filtering results far superior to URL list based filters and keyword blocking filters.
