Joan Feigenbaum. (cover story)

An interview with Joan Feigenbaum, Grace Murray Hopper professor of Computer Science in the U.S., is presented. When asked on access controls and encryption incapable of protecting privacy, he said that people who expressed desire for privacy do not mean they want their sensitive information hidden. He asserted that the challenge is to support appropriate use of sensitive information, not to prevent all use by preventing disclosure. He expressed his views in the controversy over Net neutrality.
