Health Websites are NOT Confidential!

Beware of using health websites as a new study (reported in Money, April, p. 20) reports that many health websites "leak information about your health concerns."  The study was conducted by a doctoral student at the University of Pennsylvania who found that on 91% of the websites third parties could access information on users! 70% of the websites revealed information that could be used by data brokers who sell information to marketers. To thwart this breach of confidentiality, use browser extensions such as Ghostery and Adblock Plus.
