When physically together, users can view photos jointly on a device such as a smartphone, tablet, smart TV, etc. During such a session, inadvertent disclosure of photos not shared jointly with all viewers can happen. This disclosure describes techniques to automatically set photo visibility on a device being viewed by multiple users. With user permission, the front-facing camera of the device is used to capture an image of all viewers. The viewers are mapped to user identifiers and access control techniques are implemented to select photos that are viewable by all viewers. All other photos are set to protected mode and can only be viewed with specific action by the device owner. The techniques improve the user experience of joint photo viewing while preventing inadvertent exposure of private photos.
