What do we mean by privacy?• Louis Brandeis (1890)– “right to be left alone”– protection from institutional threat:

government, press

• Alan Westin (1967)– “right to control, edit, manage, and

delete information about themselves and decide when, how, and to what extent information is communicated to others”

Privacy vs. security

• Security helps enforce privacy policies• Can be at odds with each other– e.g., invasive screening to make us

more “secure” against terrorism

Privacy: what information goes where?

Security: protection against unauthorized access

Privacy-sensitive information

• Identity– name, address, SSN

• Location• Activity– web history, contact history, online purchases

• Health records• …and more
