One of the world’s most popular means of communication, Facebook's WhatsApp, is adding fully encrypted video calling to its messaging app on Monday, a move that comes as privacy advocates worry about the potential for stepped-up government surveillance under a Trump administration.
WhatsApp, which boasts more than a billion users worldwide, adopted end-to-end encryption early this year, making it technically impossible for the company or government authorities to read messages or listen to calls.
The new video calling service will thus provide another means for people to communicate without fear of eavesdropping though WhatsApp does retain other data such as an individual's list of contacts.
WhatsApp co-founder Jan Koum said in an interview that video calls will be rolled out to 180 countries within hours after the feature is introduced at an event in India.
“We obviously try to be in tune with what our users want,” Koum said at the company’s unmarked Mountain View, California headquarters building. “We’re obsessed with making sure that voice and video work well even on low-end phones.”
Koum told Reuters that improvements in phone cameras, battery life and bandwidth had made the service viable for a significant proportion of WhatsApp users, even those using inexpensive smartphones.
