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

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.

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)
Also, surely children accessing images of violence is going to harm them a lot more.
Another foolish left-wing conspiracy theory. Your xxx domain example is just horrible. The government knows that publishing content under .com, .net, .org, etc, is a right, and they did not interfere with the industry's ability to publish content under any domain they choose. You see, they were PROTECTING the rights of the adult entertainment industry. You really have it backwards.
And now, they are doing a STUDY to determine which methods best accomplish the goal of upholding the adult-content distribution problem, and they were careful to ask for data that would not violate any person's rights.
The governmetn is working to address everybody's concerns in this matter while protecting our freedoms. Your loony conspiracy theory is... just that. Loony.
I have to buy my essentials because it infringes on my rights as not respecting me being a religous person. The same applies to putting pictures on cosmetic products which show partial nudity or billboard adverts. In other words freedom and respect go hand in hand. Otherwise you have anarchy. What I am saying is consider the feelings of religous people as well even if you may not have the same beliefs as them.That is what a multicultural society and democracy is all about.

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.
My point here is that it takes active monitoring, and there is no infrastructure in place at this time to do so outside of filtering applications.
Secondly, you are proposing to take away a freedom/right... A company can buy whatever unclaimed domain they can think up... and publish the content that they choose to publish. This is a freedom. Now you want to tell everybody in the country what domain extensions they must use, and what content belongs under which domain extension... never going to work. How do you police THAT?? Subpeona more records from Google, I suppose........

Do people still randomly type in www.????.com? I thought people clued into this a long time ago. If not...now you know! :)

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!

- I love tecnology and cnet is my source of news too, I do not however, believe that an intrest in this portrayal of human sexuality is a very good one at all. Thus, I believe that wanting and desiring to see it online is not a good indication of 'intrest in it'. I am however not in favor of personal webfilters, I believe that they only widen the chasm between the parents and their children. This is because normally children are presented a picture of trust until the trust is broken and a premptive action such as this does not agree with that. I think that the possible psychological side effects far outway the need for a personal webfilter. Finally webfilters are relatively easy to get past anyhow as stated in the article.
