at the right time and they click it, we win.»

glasses to someone searching for binoculars
that you somehow infer is a woman.»

Privacy Problem
• Aggregation
• Distortion
• Exclusion
• Secondary Use
• Chilling Effect
Privacy Problem - Aggregation
• Creation of Super-profiles
Search by search, the profile and identity of user become "transparent" over
time.
«French mountains»
«ski vacation»
«Christmas deals»
«gift to grandchild»
«NY Paris flights»
«category D car rentals»
«five star hotels disabled access»
Privacy Problems – Distortion
• Information may be highly misleading
«assassinate US president»
• imply criminal intent?
• a student writing a history seminar?
«growing marijuana»
• teenager considering use of drugs?
• parent concerned with growing drug use?
Privacy Problems – Exclusion
• Identity – Anonymity
• 89% believe web searches private,
• 77% believe Google Web Search do not reveal their personal identities
• Misguide
• Privacy policy
• IP -> internet protocol address
• 4 Clicks to reveal what is a «Server Log»
Privacy Problems – Secondary Use
• Improve own services
• Mining - Use and Reuse of the data
• Future use of their data
• Breach of confidentiality
• betrayal of the user giving out information
• Ingress
• Expectation -> Real World Role Playing Game
• Reality -> Application to Improve Google’s Location Services
Privacy Problems - Chilling Effect
• Increased public awareness
• Decreased use of search engines (self-censorship)
• "free Taiwan" in China
• «Bin Laden 9/11.»
• Data mining in e-mail
• Personal usage?
• Professional usage?
• Indirect usage?
Conclusion
• “Perhaps the most difficult privacy issues in all of human history”
Edward Felten, a privacy expert at Princeton University
• Billions of queries stream
across Google’s servers each day.
“the aggregate thoughtstream of humankind, online.”
Conclusion
• Users may accept use of their personally identifiable information
by a company that offers an amazing service for no apparent cost.
• Huge Data Ocean
• Individual rights disapperead
• Protected and Unprotected Data
• Redraw the boundaries
