A new mobile app for Apple devices called Wickr lets people exchange files and messages without leaving digital traces that could be examined by law enforcement or cyberspies. San Francisco-based Wickr offers a system that is based on heavy encryption, no log files and a robust data destruction system to ensure data stays secret forever. The only real way to see something sent to a Wickr user would be to steal the person’s phone. A free version of Wickr is available in Apple’s App Store, and an Android application is under development.”]
