Blocking all explicit material impossible, library official says
The Pittsburgh Post Gazette takes a Look At Filtering. A computer expert yesterday told a County Council subcommittee that is considering legislation to block all pornographic material in Allegheny County's 44 public libraries that even the most sophisticated filters will let images through.
"Most filtering systems are very good at blocking texts and [specific Internet addresses]," said Dan Jude, chief executive officer of Security Software Systems, a Texas-based company. Unfortunately, he said, no technology is available to block sexually explicit graphics and photos.
