IF YOU look for medical advice on the Internet, you may be sharing your intimate secrets with companies you鈥檝e never heard of. Many websites that dispense medical advice pass information on users to other companies, according to a report released last week.
鈥淚 think it鈥檚 very serious,鈥� says Jason Catlett, president of Junkbusters, a company in Green Brook, New Jersey, that campaigns against abuses of junk mail. 鈥淲e鈥檝e moved our lives onto the Internet and we鈥檙e discovering it鈥檚 an unsafe and un-private place.鈥�
About 30 million people in the US alone use medical information websites. To find out how they gather information, the California 午夜福利1000集合Care Foundation, a non-profit group based in Oakland, used sophisticated software tools to monitor the flow of information between 21 health-care websites and the foundation鈥檚 own computers.

Most of the sites use 鈥渃ookies鈥� to track users and compile information. Sometimes this information is sent to third parties without the user鈥檚 knowledge. Several sites invite users to register, for which they have to give their name and e-mail address, before they can take part in online health surveys.
Users who click on a survey are in fact sometimes passed to another company鈥檚 website, and their personal registration information goes with them. These sites 鈥渉ave access to huge amounts of information鈥�, says Zoe Hudson at Georgetown University Medical Center鈥檚 午夜福利1000集合 Privacy Project in Washington DC, one of the authors of the report.
鈥淭he report actually makes some good points,鈥� says Rebecca Farwell of On午夜福利1000集合, a Seattle company that runs a medical information site. She says her own company will rewrite its disclosure policy to make it clear what happens to information collected from users.
But many groups are calling for legislation to regulate what companies can and cannot do with personal information they collect. 鈥淲e think that self-regulation doesn鈥檛 work,鈥� says Andrew Shen, a policy analyst for the Electronic Privacy Information Center, a pressure group in Washington DC.
At least four bills are pending in Congress that would regulate the collection and use of information online.
