Snowden co-designs a surveillance-proof phone case - UPI.com
UPI reports: "Infamous whistleblower Edward Snowden has co-designed a smartphone case that can help people elude surveillance. [...] The case is called "the introspection engine," and it would alert the user whenever the smartphone's radio signals are being sent, something that can happen even if your phone is on 'airplane mode.'"

Comment: Missionaries and human rights workers operating in repressive countries might want to look into this tech when it becomes available.
