File-sharing realities for families
You may have heard terms like "file-sharing," "music-downloading," peer-to-peer" ("P2P" for short). If you haven't, you must not have an online music fan at your house. If not, the only reason why you might want to keep reading is to find out what all the fuss is about - thousands of recording-industry lawsuits and lots of news about musicians' rights and music piracy.
If there are digital music fans at your house, you might want to read on. There are legal, financial, ethical, PC-security, and sometimes children's-well-being risks involved in using the Internet's file-sharing networks.
First, some parents might want to know exactly what this P2P thing is. For one thing, it's huge: now one of the most common online activities[1], with more than a billion music files downloaded each week. In fact Internet service providers are scrambling to deal with all the file-sharing traffic passing through their servers - it uses more bandwidth than Web traffic, sometimes doubling it.[2] For young people, file-sharing is right up there with instant-messaging and gaming in the Top 5 tech activities. Even back in 2003, half of all 12-to-22-year-olds had done some file-sharing.
The simple reason: music. People of all ages have always loved to share music, and - just as with digital photography - the Internet has made it extremely easy to share tunes with friends, wherever they are.
How does it work?
Each file-sharing service is a little different, but basically...
A would-be file-sharer goes to a P2P Web site and downloads its software onto the family computer. That software turns your computer into a node or part of that P2P service's network, opening it up to fellow file-sharers on it (other people who've downloaded the software).
With older P2P technology like Kazaa's, the software creates a "shared media" folder on your computer, to which s/he downloads tunes and from which other people on the network can select and take songs. In some such software programs, you can disallow sharing so that users at your house can download music but nobody else can find and grab tunes from your computer. In other words, you're downloading but not sharing (for P2P history, see, the site of 18-year-old specialist in "Computing, Psychology and Music Technology" Rob Wright in the UK).
Newer file-sharing technology like BitTorrent doesn't give the file-sharer that option. While you're downloading you're also sharing - but only the song, movie, game, etc. you request. (In BitTorrent's case, you download fragments of songs and other files from many computers all at once, which makes it much faster, thus its phenomenal growth and popularity among sharers of large media files.)
The ultimate effect is an instantly accessible, global music library available to anybody connected to the Net anywhere - another very attractive proposition, but not at all attractive to media companies who stand to lose a great deal because of this giant "public library."
Which brings us to the risks....
Legal risk. The International Federation of the Phonographic Industry (the umbrella organization for recording industry trade associations worldwide) says in its Web site that "unauthorised copying and dissemination of copyrighted works is theft."[3] Note the pairing of "copying and dissemination." When file-sharers both download and share, they - and, if they're minors, their parents - are at risk of being sued.
An article in the New York Times focusing on legal music adds some clarity: "Downloading music from the Internet is not illegal. Plenty of music available online is not just free but also easily available, legal and - most important - worth hearing. That fact may come as a surprise after highly publicized lawsuits by the Recording Industry Association of America.... But the fine print of those lawsuits makes clear that fans are being sued not for downloading but for unauthorized distribution: leaving music in a shared folder for other peer-to-peer users to take."[4] In other words, there is currently little legal risk for music downloaders who configure their file-sharing software not to allow sharing. A lot of file-sharing software programs make this an option. But this is not always an option, for example with BitTorrent - something all file-sharers need to check out in the preferences or options of the P2P software.
That's the risk question, then there's the purely legal one. All the legal ins and outs - from burning CDs for friends to the difference between listening to and downloading online music - are addressed in a FAQ written by cyberlawyer Parry Aftab of Wired Safety. Childnet International in London provides both UK and US perspectives, as well as "Young People, Music, & the Internet," a Web site and an educational leaflet for parents that is being printed in eight languages and distributed in 19 countries. As for file-sharers themselves, Microsoft's WebSafeCrackers, designed by and for youth, has a whole section on P2P called Nick-star.
Of course there are ethical questions too: e.g., is it ethical for somebody's entire music collection to have been free, with no compensation to the copyright owners? What happens to songwriters and bands when this part of their income is taken away? A New York Times article, "No Fears: Laptop D.J.'s Have a Feast," points to many spots on the Web where music is free and legal, artists get compensated, and where the sound quality of the music is even reliable. And of course there are some great pay-per-tune sites - lists hundreds of online music retailers by region of the world and other music destinations on the Web.
Porn in P2P. The file-sharing services allow for sharing photos and videos, as well as music, software, games, and text documents. Some of those images and videos are pornographic. Studies have shown that porn is being widely shared on the P2P networks, even more than music on some.[5] [WinMX, for example, is "full of porn," an experienced file-sharer told me, "but by default it only searches for music so you don't get porn unless you're looking for it."] Children can download porn by mistake because in some cases the descriptive labels that identify these files aren't accurate. And standard filtering software rarely blocks porn on P2P networks. Filters are generally designed to detect and block URLs, or Web addresses, and keywords on Web pages, not P2P file descriptors, especially if they merely use a celebrity's name. Even files named with characters such as Winnie the Pooh or Pokemon have been found to be pornographic. Kazaa, however, has a "Family Filter" (described in its Parents' Guide) that you can configure to block images and videos altogether.
Family Privacy. This is a less well-known but well-documented risk, and parents need to know about it so they can protect what's on the family computer. File-sharers are inadvertently making a lot more than music available to the millions of people on the P2P networks. Emails, medical records, and family financial information have been shared during file-sharing. The services themselves don't do a good job of telling users that they have to be careful about what folders on their hard drive they open up to the file-sharing public. A 2002 study of Kazaa at HP Labs in California found "the majority of the users in our study were unable to tell what files they were sharing, and sometimes incorrectly assumed they were not sharing any files when in fact they were sharing all files on their hard drive."[6] Congress later held hearings on this problem to get the word out.[7] Recent testimony in a FTC workshop on P2P[8] indicated that Kazaa "had significantly improved" in this area, and "other software, such as eDonkey, did a good job of clearly indicating to users exactly which files are being shared." BitTorrent represents "virtually no risk" where inadvertent file-sharing's concerned.
Spyware. The biggest pest plaguing the P2P networks is spyware - little software programs that are downloaded with music and other files or "bundled" with the file-sharing software some of these services provide. The least threatening sort slows your family PC down by loading it up with little Web-tracking programs that follow your movements around the Web. Too many can eventually disable the computer. Kazaa, for example, is reportedly loaded with spyware[9]. But now even BitTorrent users are downloading it (see my 6/24/05 issue). Some of these little software surprises are even more intrusive - the kind that logs your keystrokes and provides the person who controls it with passwords, credit card numbers, and other confidential information on the computer. This too can be inadvertently downloaded from other people's computers on the file-sharing networks.
Viruses. Remember that the P2P services are actually huge networks of individual machines linked together by the software they provide. These days, viruses and worms rarely do real damage to individual PCs. Now they're more likely to install "trojan" software that allows your PC to be controlled by someone else - such as spammers who want to make money by using thousands of "zombie" PCs to send ads about low-cost mortgages and cheap drugs. Because standard anti-virus software doesn't detect viruses downloaded via P2P, file-sharers' computers are vulnerable to the viruses on other machines on the P2P networks and to the people controlling them. If your child downloads Kazaa, your PC could be used, among other things, as a porn spam distributor. One US study found that nearly half of the files on Kazaa contained viruses or other malicious code.[10] "In my opinion," a file-sharer confided, "the FastTrack network [of which Kazaa is a part] is slowly dying; now it's so full of viruses it's unusable."
Hard-drive clogging. Computers' storage capacity is certainly growing, but - besides spyware - nothing loads up and slows down a computer more than media, game, and software files, exactly what's traded on the P2P networks. If your family PC has been performing slowly, file-sharing is very likely to be the culprit. See below for information on software that can tell you what media files and P2P software are on your system.
Chat. Many file-sharing networks are associated with online chat, and most parents know the potential, here, for children to be contacted by strangers. This is definitely not the biggest risk in file-sharing (a P2P ueser recently told me file-sharers generally don't chat because they like to stay anonymous), but it'd be good to include this in any family discussion on file-sharing. If chat's allowed, a good rule would be never to discuss anything but the content being shared and don't let any online relationships with strangers develop from those conversations. Don't miss for all the information a family would need on this online-safety risk.
Talk about file-sharing together. A lot of parents don't have any idea what's happening on the family computer where file-sharing is concerned. A family discussion is always the best first step. See what your kids will tell you, ask them to show you how it works, and - before you make any decisions about stopping or allowing household file-sharing - find out what everybody's thinking about the ethics and legalities involved, whether porn's been stumbled upon, how the PC's performing, whether there's spyware protection, etc.
Configure the software with your child. If you allow file-sharing, at least make sure everybody's clear that the preferences and options in each P2P program are configured for maximum PC and child security - whether or not you actually sit down and configure the software with older teens. If you allow sharing, make sure nothing but media files are shared. Check to see if the program has a "private sharing" feature (allowing sharing only with designated friends, like a "buddy list") and consider choosing that option if available. If Kazaa is the P2P service of choice, check out its "Family Filter" and - to minimize kids' exposure to porn - consider using its feature that blocks all image and video files. Also visit the site where the P2P software is downloaded (e.g.,, LimeWire, or and see if they provide any tips for parents, care-givers, and other PC owners for safe use.
P2P parental controls. File-sharers probably won't like this option, but there is software that gives parents some control over P2P activity on the PC. One option is SmartGuard, Inc.'s Blockster, which monitors and blocks file-sharing software, giving parents an unhackable override password for all such programs on the system - anything that allows the transfer, or sharing, of files from that PC, including IRC chat. Some file-sharing services themselves are now offering parental controls
P2P monitoring. links to free P2P-detection software available for the downloading at the International Federation of the Phonographic Industry's site. The US's film industry trade association (the MPAA) recently made similar software available for free at With this software, parents can find out what file-sharing programs and media files (music, photos, movies, etc.) are on the PC and choose whether or not to delete them.[11]
Possible family P2P policies
Here are several ways to go for musically minded families (customize them for your family!):
  • Send the message: "Download legal music only" (see this New York Times article or's listings for sources) and - if file-sharing services are used, disable the sharing part of the program or allow only private sharing, if the software has these features. Rules that might go with this policy: Keep it legal; download only music (not photos, videos, TV shows, films); have an anti-spyware app installed and scan and delete spyware at least weekly; tell us if you happen to download anything strange. Risk: that kids will accidentally download viruses and, if sharing's enabled, distribute them.
  • Don't allow "traditional" file-sharing services. As a family, develop a list of free-and-legal music download sites; set a family budget for downloading at pay-per-tune sites like iTunes, MSN Music, Napster, etc.; allow a service like for file-sharing among friends and relatives and/or the new legal file-sharing services ( and iRate radio - see "Legal alternative" below") good for finding new music and not-yet-discovered musicians. [For more on the Grouper and other evidence of the growing "private file-sharing" phenomenon, see "File-sharers gone underground" in my 10/15/04 issue.]
  • Establish a policy or set of rules for online music that may include some of the above points - whether or not you allow file-sharing - and install software like Blockster as a deterrent or negotiating tool. Remember this works only on computers over which you have control - not the ones at libraries, friends' houses, etc. The Net is getting increasingly mobile, for kids and everybody else!

  • Online music update, 4/6/06. Music file-sharing hasn't been on US media radar screens much in recent months, but it certainly was across The Pond this week. File-sharers face what the BBC called a "legal onslaught," as the IFPI, the international umbrella for recording industry associations like the US's RIAA, announced it was suing nearly 2,000 P2P service users in 10 countries. Reuters added that the IFPI released data showing it had lost 1 billion pounds ($1.8 billion) in the past three years, due to file-sharing. Meanwhile, if you're looking for legal ("podsafe") music to enhance your homemade videos (so they won't get deleted from because the copyright owners complained to the Webmaster), PCWorld has some sources (and explains "fair use" in these days of self-published media). Finally, the Associated Press updates us on the argument between Apple and the record labels on pricing of legal online music.
  • Record label helps family. Canadian record label Nettwerk Music Group is helping a Texas family fight a file-sharing lawsuit from the RIAA, MTV reported 1/27/06. Nettwerk said it would pay all legal fees and any fines for the family if it loses, according to MTV. The RIAA is demanding that the parents, whose 15-year-old daughter allegedly shared 600 songs, pay $9,000 to settle, or half that if they comply with its settlement agreement. Nettwerk gave two reasons for supporting the Greubels: 1) because a song by one of its artists, "Sk8er Boi" by Avril Lavigne, was among the nine songs named in the lawsuit and 2) because "suing music fans is not the solution, it's the problem."
  • BitTorrent in deal with film industry. Bram Cohen, who wrote the BitTorrent P2P software, has agreed with the MPAA (Motion Picture Association of America) to stop providing links to copyrighted films on his Web site, British tech-news service VNUNET reported 11/24/05, "and hopes to be able to license movies and TV programmes that could be downloaded for a fee." BitTorrent reportedly has been downloaded 45 million times, and VNUNET adds that the software "accounts for 33-50% of all Internet traffic in Asia partly because it increases the speed of file sharing 15 to 20 times over conventional services.
  • P2P history at a glance. See the sidebar at the bottom of this 10/15/05 Wall Street Journal profile of "DVD Jon," "the 21-year-old Norwegian who defied Hollywood to help the world copy DVDs."
  • IFPI releases free P2P-detection software for home computers (see our 9/30/05 issue for details).
  • P2P services going "legit", following the US Supreme Court decision in late June. "At least five online file-sharing companies have started trying to reach an accord with the music industry to convert the free trading of copyrighted music on their networks to paid services," the New York Times reports, citing Grokster (which had the title role in the Supreme Court case), eDonkey, Morpheus, LimeWire, and iMesh. Grokster, furthest along in discussions, has agreed in principle to be acquired by MashBoxx. The latter, which is backed by Sony and says it'll be up and running by the end of the year, will use technology developed by Shawn Fanning (founder of the original Napster) - a "system of digital fingerprinting to track songs," USATODAY reports. There was also news this week in late September of P2P services shutting down. It'll be interesting to see what new tools file-sharers will develop, because work-arounds are known to happen on the Net.
  • Kazaa decision. On 9/5/05 an Australian federal court ordered Kazaa to modify its software to reduce the copyright infringement happening file-sharers using its service, ZDNET Australia reported. The court said Kazaa could remain in operation if it complied.
  • Video surpasses music: In an 8/11/05 report, cited a new study by UK P2P traffic researchers at CacheLogic showing that "video content now makes up almost 62% of all traffic on the four largest P2P networks - BitTorrent, eDonkey, Gnutella and Fastrack, the network used by Kazaa." Audio now represents just 11% of all P2P traffic, with "the remaining 27% being dedicated to 'other' content, such as games and software."
  • eDonkey the new No. 1: It has surpassed BitTorrent as file-sharers' favorite means of swapping movies, music, games, software, etc., CNET reported 8/28/05 . That's according to the latest P2P traffic-measurement study by UK firm CacheLogic. A year ago CacheLogic found that BitTorrent file-sharing accounted for half of all file-sharing activity, and file-sharing accounted for 50-70% of all "data traffic on ISP networks," surpassing even Web use. New No. 1 eDonkey is "a rival with more power to search for content," but with "speedy download features" similar to BitTorrent's. Edonkey "has been translated into local languages in many countries around the world, aiding its spread overseas," CNET adds. The Good Morning Silicon Valley blog pointed out that lawsuits do seem to cause migration from one P2P technology to another (Gnutella, once considered dead, is back in the running).
  • Open-source downloads unabated. "Millions of people a week [emphasis mine] are downloading and using those independent [P2P software] programs" like Azureus (a BitTorrent application that also runs on Macs) and Shareaza, CNET reports in a 7/15/05 article that surveys the scene since the US Supreme Court's MGM V. Grokster decision in June. "Azureus has been downloaded more than 78 million times, and more than 2.4 million times in the last week alone," CNET says. Meanwhile, commercial providers like LimeWire and MetaMachine (which markets eDonkey) are taking a hard look at their businesses.
  • Legal alternative: The Los Angeles Times describes two programs, Indy and iRate radio, which help digital-music fans find new tunes. How it works: The software downloads to your computer "a number of songs that artists have agreed to distribute for free online. Each time the programs run, they download more songs for users to play and rate on a scale from one to five stars." The really interesting part is "collaborative filtering," which is more about humans than technology but uses both. "The ratings help the software match each user to others who have parallel likes and dislikes." It's legal file-sharing. [Tip for parents: Ask your kid(s) if the computer can handle all the music being downloaded. Maybe they'd like to try this instead of file-sharing?]

A 2002 US Government Accountability Office study (cited in a 2005 FTC report on file-sharing) found that, in a search of popular singers, actors, and cartoon characters on Kazaa, 49% contained "some form of pornography." A 2003 corporate-funded study found that porn accounted for more than 40% of the traffic on the Gnutella network, which connects P2P services like Morpheus, LimeWire and BearShare, and the illegal form of it - child pornography - 6%. Some pedophile rings actually use the P2P networks as their distribution channels. Here's 2003 CNET coverage of a US House of Representatives subcommittee report on porn on P2P networks.

You find pornography on your child's computer.
Pornography is often used in the sexual victimization of children. Sex offenders often supply their potential victims with pornography as a means of opening sexual discussions and for seduction. Child pornography may be used to show the child victim that sex between children and adults is "normal." Parents should be conscious of the fact that a child may hide the pornographic files on diskettes from them. This may be especially true if the computer is used by other family members.
