Technology: Whatsapp adds end-to-end encryption; Viber to by-pass blockage |

e says Viber does not “have the capability to listen to conversations”. Messages are stored, for two weeks or until they are opened by the recipient, whichever is shorter. Around 80% are deleted in less than a second. The messages are encrypted, and Marco says he has never handed the encryption key to any government. “We have been asked if we would co-operate. We never provided anybody with anything that will let them listen to conversations or messages on Viber. I do believe people should take notice of the fact that the Saudi government has threatened three companies with shutdown of service – us, Skype and Whatsapp. Only one company was shut down. Users should ask themselves why the other companies were not shut down.
