WhatsApp already has this new functionality enabled that allows the recipient to see the photo they receive only once. In this way, WhatsApp works on the security of all users who many times, without being aware of it, pass photos of their bank or personal details that are then left in the receiver's image gallery.
Activating the "single view" mode also discourages "sextortion" defined as extortion of the person for having sexual photos or videos of the person.
Some of the features of the functionality:
- End-to-end encryption of both photos and videos sent
- The files under this functionality are not saved neither in the photos section nor in the Gallery of the person who received them.
- The receiver can see the photo only once.
- Photos or videos sent under this functionality cannot be shared, saved or any other option other than viewing only.
- Files last 14 days in chat for the recipient to see; after that period of time the photo or video disappears.
