Facebook is supposedly dealing with enabling encrypted video and audio employ Messenger.
App scientist and enthusiast Jane Wong learnt about the unreleased function. They shared through Twitter a screenshot of a Secret Discussion with audio and video call icons on the top corner. It also states the calls will be "end-to-end encrypted across all your active mobile devices."
The encrypted video and audio call function will be an extended ability of the secret conversations released in 2016.
Messages sent in "secret conversations" are end-to-end encrypted. It means that only the sender and the receiver have access to the messages. Not even Facebook can see them. Furthermore, the messages will just be offered on chosen devices. Users can also set timers that will make the messages vanish after the indicated period.
The secret discussion feature of Messenger utilizes the same procedure as Signal, an open-source privacy-focused messaging app developed by Open Whisper Systems.
Facebook presented this function to secure users when talking about personal details, which might be associated with health issues, diseases, or when sending financial details. With the addition of encrypted audio and video calls, the function will have more use cases.
However, it is still unclear if and when the extended capability of the secret discussion function will be launched.
