The WhatsApp application will allow users, in the coming weeks, to encrypt the backup copies of messages stored in the cloud, making them incomprehensible to anyone who might try to read them without a password.
“WhatsApp is the first global messaging service of this scale to offer end-to-end encryption for messages and backups,” said Facebook co-founder and CEO Mark Zuckerberg, quoted in the news.
Facebook’s platform has been encrypting communications between users for several years, so that only the sender and recipient can be the only ones to see the messages. “Getting to this point was a very difficult technical challenge that required a completely new framework for password and cloud storage across multiple operating systems,” added Mark Zuckerberg.
Now, the new security method will be available for backups that are kept on cloud storage services from companies like Google or Apple (Drive and iCloud, respectively).
According to WhatsApp, no intermediary or hacker will be able to access messages without permission. The measure will imply that, if the user chooses the new backup option, neither WhatsApp nor the companies providing cloud services (Google and Apple), not even the security forces will be able to read the messages without having a password to interpret them.
Using these unencrypted WhatsApp dialog backups on Google and Apple servers is one of the widely known ways in which security agencies around the world have been able to access the WhatsApp conversations of suspicious individuals.
WhatsApp, acquired by Facebook in 2014, has 2 billion users worldwide, making it the most used online messaging platform. The encryption option will appear, first, to iOS users and, shortly afterwards, to the rest in the coming days.
