(54) Title: SHARING PROTECTION FOR A SCREEN SHARING EXPERIENCE (57) : Techniques for sharing protection for a screen sharing experience are described. In at least some embodiments, a screen sharing experience involves a user sharing portions of their display screen with other users as part of a com- munication session. According to various embodiments, a user that is sharing their screen with other devices as part of a screen sharing experience can protect a por- tion of the screen from being shared by designating the portion as sharing protect- ed. Thus, content from the identified portion of the user's screen is encrypted to prevent other devices that are unable to decrypt the content from viewing the con- tent. According to one or more embodiments, a user can be designated as sharing privileged such that the user is permitted access to an encryption key to decrypt and view sharing protected as part of a screen sharing experience.
