The NSA whistleblower, Edward Snowden, has urged lawyers, journalists, doctors, accountants, priests and others with a duty to protect confidentiality to upgrade security in the wake of the spy surveillance revelations. Snowden said professionals were failing in their obligations to their clients, sources, patients and parishioners in what he described as a new and challenging world. What last year's revelations showed us was irrefutable evidence that unencrypted communications on the internet are no longer safe. Any communications should be encrypted by default," he said. Snowden's plea for the professions to tighten security came during an extensive and revealing interview with the Guardian in Moscow. During the seven hours of interview, Snowden: Said if he ended up in US detention in Guantnamo Bay he could live with it. Does not have any regrets. Said that ... he was independently secure, living on savings, and money from awards and speeches he has delivered online round the world. Made a startling claim that a culture exists within the NSA in which, during surveillance, nude photographs picked up of people in "sexually compromising" situations are routinely passed around. He works online late into the night; a solitary, digital existence not that dissimilar to his earlier life. He said he was using part of that time to work on the new focus for his technical skills, designing encryption tools to help professionals such as journalists protect sources and data. He is negotiating foundation funding for the project, a contribution to addressing the problem of professions wanting to protect client or patient data, and in this case journalistic sources.
