ABSTRACT
The World Wide Web presents a vast sea of information. Since the Internet first came online in late 1969, the number of users has grown to more than 600 million worldwide. The challenge facing the user is to find the best possible resources to meet his or her specific needs. An added complication is the fact that some of what is offered via the Internet can be less than authoritative, offensive, or even dangerous, and regulations that govern other resources are lacking. This is a matter of particular concern to adults who are worried about the access children may gain to pornography, hate materials, or just plain erroneous information. One solution to this dilemma has been information filtering devices. Strictly speaking, an Internet filter is an application that accepts information as input and changes or transforms it to meet certain specifications.
