Conventional wisdom holds that in a post-Edward Snowden world, app users have started worrying government surveillance of their lives and are crying out for technologies that guarantee privacy.
End-to-end encryption (with forward secrecy and user verification), licensed from Open Whisper Systems in 2014, does this because the keys used to encrypt data are generated by mobile devices and are never stored on Whats App servers.
Crucially – and this is the bit to pay attention to – law enforcement agencies who turn up at its offices can’t either. End-to-end encryption helps make communication via Whats App private, sort of like a face-to-face conversation.” In addition to video calls, Whats App users now enjoy this security feature for messaging and phone calls too.Voices can be hard to recognise reliably on poor-quality links, and video may be unrecognisable.
