Do Web filters protect your child?

Last modified: January 24, 2006 9:29 AM PST

update Millions of parents around the country rely on Web filtering software to shield their children from the nasty side of the Internet--porn, predators and other unseemly phenomena.

But according to the U.S. Justice Department, Web filters are not enough to protect minors. The agency voiced its concern about the technology last week as it geared up to defend an antiporn law that's under attack from civil liberties advocates.

The case, which deals with the 1998 Child Online Protection Act, grabbed attention Thursday after the department subpoenaed Internet search companies, including Google and Yahoo, for millions of search records.

Prosecutors said they need the records to understand the behavior of Web users and how frequently they encounter pornography. Internet addresses obtained from the search engines could be tested against filtering programs to evaluate their effectiveness, the agency said in a court filing.

Casting doubt on the usefulness of Web filters should put American families on edge. More than half of U.S. families with online teens use filtering programs, with more than 12 million copies of such software in use, according to a study conducted last year by the Pew Internet and American Life Project. The report indicated that use of filters in U.S. homes grew 65 percent from four years earlier, as children logged on to the Web in ever greater numbers and the online porn industry continued to flourish.

So just how well do such tools really work? Experts say the technology is not flawless but that it's become more sophisticated in recent years. For instance, developers of filters have learned to thwart some of the more common devices designed to disable them and have added more customization features that give parents greater control over the type of material that can be blocked.

"They're not perfect, and it's hard to see how they ever really would be," said Amanda Lenhardt, a researcher at the Pew Internet and American Life Project. "But they are relatively effective. They do a reasonably good job."

The Consumers Union, which publishes Consumer Reports, agrees. The company re-evaluated 11 products in June, concluding that filtering software has improved since a previous report in 2001 but that the products are "still fallible."

"Filters keep most, but not all, porn out," the group writes in an online overview of the report.

The products that scored highest in the Consumers Union's evaluation were Safe Eyes from SafeBrowse.com, Microsoft's Parental Controls, CyberPatrol from SurfControl, Symantec's Norton Internet Security and McAfee's Privacy Service. Most took just minutes to set up, the group said.

"We've come a long way from the days when searching on 'Little Bo Peep' would yield adult sites for the first 20 listings," said Ray Everett Church, a privacy consultant at PrivacyClue, a research firm.

Web filtering software blocks access to objectionable material through a variety of methods, including blacklists, keyword lists, content rating systems and white lists. Blacklists consist of a predetermined set of Web addresses and will not let users visit specific Web pages.

A keyword list actually scans Web sites for undesirable text and, in some cases, images. If it finds a match, the browser refuses to render the site or pops up a warning. White lists, considered the most restrictive method, block access to all sites except those selected by the filter company. Some filters also work in conjunction with Web site ratings, a voluntary system that relies on Web developers providing an honest description of their content.

Some Internet service providers, including AOL, also try to do their part. Twenty-five percent of AOL's 20 million members sign on under parentally controlled screen names.

"It is a robust and multileveled set of controls to help ensure kids don't have access to inappropriate content and do have access to useful and appropriate content," said AOL spokesman Andrew Weinstein.

As advanced as some of these programs have become, Internet

Take responsibility for your children
by rcrusoe January 24, 2006 6:01 AM PST
Some filters are better than others, but the best solution for protecting children online is parental supervision.

Don't let your child have a computer in their room, put it in a public area in your home. Teach them how to avoid the dark/dangerous areas of the net, and only allow them to use the computer when a parent or guardian is at home.

If you don't know how to do the above - Learn.

The government is good at some things. Controlling content on the Internet, a global entity mostly outside the reach of U.S. laws, is not one of them.

Who cares? Like the guy said, who's ever been permanently harmed by accidently coming across porn when they were young?

The Government is smoke screening
by bemenaker January 24, 2006 7:03 AM PST
The government's intent here is not just limiting the access of pornography to kids. If that was their intent they would be taking a totally different approach on this subject. The current administration is trying to launch an outright attack on pornography in general.

If the government really wanted to make pornography easy to filter out so that you could simply protect you kids, they would not have opposed the .xxx high level domain. In fact, they would have embraced it, and put a caveat in there that all pornography MUST be in the .xxx domain.

The government refusing to accept and embrace the .xxx domain shows that they have no interest in actually working to rectify the problem, and allow pornography on the internet, and make an easy way to filter it out for kids. This tatic shows that they have one intent, and one intent only, to remove pornography from the internet. (Like that is possible)

This is incredibly easy to fix
by Erik the Beige January 24, 2006 7:13 AM PST
This problem has such an easy fix I'm not in the least bit surprised someone hasn't thought of it.
The .XXX domain name. Get it going. If a site is to be pornographic, it MUST be labeled with .XXX domains. Then, to block porn, simply block all .XXX domains.
If someone is caught hosting/making a pornographic site that is not .XXX, then massive fines and jail/prison time occurs.
This can't be that hard to figure out. And I'm sure other countries will jump on this idea. It can also be applied to gambling sites (.GAM) or... ok, now I'm drawing a blank as to what other sites people want to block. But there is no reason this simple idea won't work... other than it being too easy for any government to catch on to.

Yes changes have to made
by Sure Thing January 24, 2006 10:46 AM PST
Its complete chaos on the web right now. You will hit porn sites whether you intended or not that is guaranteed. I wanted to go to dilbert.com and typed dilber.com by mistake and it took me to a porn site and that was at WORK!! Also one time in college I was looking for the legend of Zelda and typed zelda.com and it was a porn site (that site was later sued by Nintendo). Point is porn sites are competing for customers and they're trying to take advantage of any keywords even those usually used by kids (like game name) and also using typos which any one can make. If adults who are not looking for porn will stumble on it, imagine what happens with kids?

...Which makes the .xxx domain USELESS!
by gefitz January 24, 2006 12:25 PM PST
None of the international nations involved in the discussion have bought into the idea of forcing "porn" to register as a .xxx domain. Unless this happens, it makes no sense at all to bother legislation in the US that porn sites must do this or that or the other thing. The point is that doing this a) will simply force porn sites the "home" in a country other than the US.

At this point, I think a large percentage of what the US considers "web-porn" is probably hosted out of US jurisdiction. So, a monolithic move to force the .xxx domain would be pointless unless other countries agree to do it as well.

Which brings up...how are all those countries going to agree on what "porn" is?

ALL A POINTLESS ENDEAVOR!
