Security or Privacy?

Written by Cara J. Hayden



The tenuous line between what people can keep private and what people must reveal for national security purposes is tricky to draw. This spring, Pitt alumna Mary Ellen Callahan (A&S ’90) was appointed chief privacy officer with the U.S. Department of Homeland Security to manage how the department addresses public versus private issues. An attorney, Callahan has specialized in privacy, security, data protection, consumer protection, and e-commerce law for more than a decade. She’s also cochair of the Online Privacy Alliance, a self-regulatory group of corporations and associations that fosters the protection of individuals’ privacy online.
