This messaging platform has 2 billion users worldwide, making it the most widely used application of its kind.
Popular instant messaging platform WhatsApp announced this Friday that in the coming weeks it will allow users to encrypt backup copies of messages stored in the cloud.
The Facebook-owned application has already encrypted communication between individuals for years, so that only the sender and receiver can see the message and no intermediary or hacker can read it, even if they manage to access it.
This security technology will now also be available for backups that are kept in cloud storage services from companies such as Google or Apple (Drive and iCloud, respectively), making them incomprehensible to those without Excuse Me. gain access to.
This means that, if the user chooses this option for their backup, neither the WhatsApp application itself, nor the companies that provide cloud services (Google and Apple), even the security forces, will be able to access them. Cannot read messages, do not have a key to interpret them.
Highly valued by activists in favor of the privacy of Internet users, this type of encryption has received much criticism from police forces and counter-terrorism organizations, as it makes it impossible for them to access suspects’ communications, even with a court order. ..
“WhatsApp is the first global messaging service of its size to offer end-to-end encryption for messages and backups,” Facebook CEO and co-founder Mark Zuckerberg said in a statement at the announcement.
“Getting to this point has been a very difficult technical challenge that requires an entirely new framework for keying and cloud storage across different operating systems,” said the social network’s head.
