As far as I know currently there is no privilege defined for setting up
window to fullscreen. (I checked on
https://wiki.tizen.org/wiki/Security:Tizen_3.0_Core_Privileges)
The closest privilege to this functionality is:
"http://tizen.org/privilege/window.priority.set"; controlling "Displaying
windows on top of other applications and screens".
As long as there is no privilege Tizen won't block any application to do
this.
If this is functionality that should be privileged we should:
* add a privilege to Tizen 3.0 privilege list;
* find service responsible for making app window fullscreen;
* use cynara in that service to control access to this functionality for
different apps;
* use privilege in manifests of application that are privileged to be
run in fullscreen mode.
Best wishes

Hi all,
I have a question about Cynara or Tizen security mechanism.
Currently, _Crosswalk_ <https://crosswalk-project.org/> of Tizen has
implemented its WebAPI "requestFullscreen" based on the
"SetFullScreen" function of Tizen native window.
Assuming Crosswalk is "untrusted", means, some malicious App can
workaround Crosswalk's permission check to invoke this function
eventually, will the system security block this invoking if the app
have not right permission label?
Thank you very much.
Peter Wang
