Danny Yadron:

Silicon Valley’s leading companies – including Facebook, Google and Snapchat – are working on their own increased privacy technology as Apple fights the US government over encryption, the Guardian has learned.

The projects could antagonize authorities just as much as Apple’s more secure iPhones, which are currently at the center of the San Bernardino shooting investigation. They also indicate the industry may be willing to back up their public support for Apple with concrete action.

Within weeks, Facebook’s messaging service WhatsApp plans to expand its secure messaging service so that voice calls are also encrypted, in addition to its existing privacy features. The service has some one billion monthly users. Facebook is also considering beefing up security of its own Messenger tool.

Snapchat, the popular ephemeral messaging service, is also working on a secure messaging system and Google is exploring extra uses for the technology behind a long-in-the-works encrypted email project.

At this point in time I would like to see more action from the other tech companies — this is obviously a delicate situation, but too much is at stake.
