Safer Internet: Talk and Chat Privately

Why?

  • chat systems+ Email does not provide end-to-end encryption, and might not be erased completely
  • + Apps can provide end-to-end encryption for text messaging, audio and/or video
  • - Not all apps / methods provide the same security or privacy.
  • - Both users usually need the same app -- unless standard protocols are used

  • Use less common apps (to avoid government monitoring?)
  • Block unwanted callers (across Phone, Messages, Facetime), e.g., in Contacts or via "i" button in Recent Calls
  • iOS: (contact) > Block this Caller

Intermediate

  • secure can[2] Consider using video (ideally) or audio instead of text -- more difficult to capture and analyze

Advanced
