Privacy: Awareness not Paranoia "privacy paradox" = lack of awareness of the public nature of Internet

“Bob Arnold” “Dogs urinating on everything” “Landscapers in Liliburn, GA” “Homes sold in shadow lake subdivision gwinnet county”

Privacy concerns • • Legal still in its infancy, but courts do rule on new behavior • 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’ fourth amendment to the U.S. Constitution & legal decisions concerning privacy are not equipped to address social network sites

Security 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.)
