From University Video Communications' catalog:"Dorothy Denning, professor and chair of computer science at Georgetown University, discusses how encryption hides information by transforming it so that the information cannot be read by someone who does not know a secret key. She makes the point that encryption can be used to both protect against criminal activity and to conceal criminal activities."
