Edward Felten, the director of the University’s Center for Information Technology Policy and a professor in the Wilson School and the computer science department, testified before the U.S. Senate Judiciary Committee on Tuesday.
Felten said that the phone records collected through surveillance by the National Security Agency could be more revealing about citizens’ personal lives than many people realize.
“Just by using new technologies such as smart phones and social media, we leave rich and revealing trails of metadata as we move through daily life. Many details of our lives can be gleaned by examining those trails,” Felten’s written testimony read. “It is no longer safe to assume that this ‘summary’ or ‘non-content’ information is less revealing or less sensitive than the contents it describes.”
The Judiciary Committee, along with a few other bodies, is investigating surveillance conducted by U.S. agencies, including the National Security Agency.
