Privacy: Awareness not Paranoia
"privacy paradox" = lack
of awareness of the public
nature of Internet
“Dogs urinating on everything”
“Landscapers in Liliburn, GA”
“Bob Arnold”
“Homes sold in shadow lake
subdivision gwinnet county”
• Legal still in its infancy, but courts do rule on new behavior
• fourth amendment to the U.S. Constitution & legal decisions concerning privacy are not equipped to address social network sites
• e.g., do police officers have the right to access content posted to Facebook without a warrant?
• Truthfulness of personal profiles has become a subject of debate
• Privacy hard to understand (few read Terms) and misinterpret ‘Friends’
Privacy concerns
security from people (sex offenders)
security of computers and data
With enormous numbers of users and enormous amounts of data, sites are natural targets of spammers, and phishing and malware attacks (‘new friend malware’, ‘twitter spam’ etc.)
