Online Ads vs. Privacy
The "New York Times" describes the difficulty of tailoring online advertisement to individuals without infringing on their privacy. Director of the Center for Internet and Society Jennifer Granick is quoted:
"But there are huge costs, and many dangers, warns Jennifer Granick, the executive director for the Stanford Law School Center for Internet and Society (wired.com). To approach individuals with customized advertising, you have to know who they are. Or at least, you have to gather enough personal information about them that their identity could be easily figured out."
"... Last fall, Ms. Granick notes, the Center for Digital Democracy filed a complaint with the Federal Trade Commission calling for 'injunctive relief' and detailing how the combination of user profiling, data mining and targeted advertising threaten privacy (democraticmedia.org)."
